A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.
The rates of change that we’re noticing are much higher than expected. If these rates continue, it is not likely that Greenland could shrink by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.
Greenland is the world’s largest island, covering area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.
Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past years, its trip to the sea has sped up from about 70 feet per day to nearly 110.
The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit(華氏溫度) in the last ten years. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen any time soon.

Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer.
This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended (混合) with flexible electronic materials to create intelligent clothing. The results are electronic garments.
If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-­free, soft to touch and washable! Like any electronic device, these high-­tech clothes have to be powered. Currently, a tiny nine-­volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100% shock ­proof, they say.
The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These “l(fā)ap-­tap” gadgets (器具)are all set to take over laptop computers!
Another useful garment is the shirt­-cum-­mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(風(fēng)帽) and the electronic ski jacket with a built-­in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.
Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
【小題1】The electronic garments are similar to other electronic devices in that________.

A．they use electricity to generate power

B．they feel smooth and soft

C．they can be washed in water

D．they are made from flexible materials

【小題2】How will researchers improve these high­-tech clothes?

A．A tiny nine­-volt battery will work.

B．The wearer will not get shocked.

C． Body heat will be used to generate electricity

D．They will get charged automatically.

Here is some news of the future.
March 20, 2035
There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would like forever, but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly, the life expectancy for seniors hasn't improved that much. Basically, you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So, do the anti-aging drugs work? Well，it is too early to tell. But the sales so far are very good.
April 19, 2035
Of the total US population of 378 million, people over 65 years of age now make up 20% for the first time. The senior ratio of only 4.1% by year 1900, and 12.4% 30 years ago.
The number of people above 65 compared to those of what is considered working ages, between 15 and 64, is currently 33.7%. This is up from 18.5% since year 2005, which means that for every retired person there are now two workers, compared to four workers 30 years ago. The number of people above the age of 80 has grown to 23.8 million, making them 6.3% of the total population compared to 3.6% in 2005.
April 12, 2040
Although introduced in the market only five years ago, 10% of all hydrogen fuel now sold in the US is of the environmentally friendly Re-Hydro label, produced through eletrolysis(電解) based on a source of 100% renewable energy. Several producers have turned to producing Re-Hydro, mainly because of lower tax, which also keeps the price of Re-Hydro on the same level as regular hydrogen. Most analysts believe that Re-Hydro will be the dominating fuel in the future.
【小題1】According to News 1 we know that the life extension drugs ____.

A．were first sold in the year 2025.

B．a(chǎn)re made to make people live forever.

C．should be taken when people are young.

D．have greatly increased the life expectancy rate at birth.

【小題2】The sales of the life extension drugs so far clearly show that_____.

A．people have no faith in them

B．people want to give them a try

C．they work very well for seniors

D．they have no effect on people’s health

【小題3】What can we learn from News 2?

A．Many Americans will find it hard to find a job.

B．It’s very hard for seniors to pass the age of 80.

C．The US population has been increasing rapidly since 2005.

D．The US population has been aging rapidly since 2005.

【小題4】We can know from the passage that the fuel of the Re-Hydro label is ______.

A．expensive

B．cheap

C．green

D．dangerous

【小題5】What can we infer from News 3?

A．Re-Hydro will be widely used in the future.

B．The government discourages the production of Re-Hydro.

C．Producers are not interested in producing Re-Hydro.

D．Re-Hydro is more expensive than regular hydrogen.

Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help?
Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind.
Consider your emotions. You might think that emotions are the enemy of decision-making, but in fact they are a part of it. Whenever you make up your mind, your brain’s emotional centre is active. University of Southern California scientist, Antonio Damasia, has studied people with damage to only the emotional parts of their brains, and found that they were unable to make basic choices about what to wear or eat. Damasia thinks this may be because our brains store emotional memories of past choice, which we use to help the present decision-making.
However, making choices under the influence of an emotion can greatly affect the result. Take anger for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems that anger can lead us to make quick decisions without much thinking.
All emotions affect our thinking and motivation，so it may be best to avoid making important decisions under their influence. Yet strangely there is one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world.
【小題1】What does the underlined word “central” mean?

A．in the middle

B．easy to reach

C．important

D．having power

【小題2】Damasia’s study suggests that ________.

A．emotions are the enemy of decision-making.

B．our brain has nothing to do with decision-making.

C．people with physical damage find it hard to make up their minds.

D．our emotional memories of past choices can affect present decisions.

【小題3】 According to the text, what may help us make better decisions?

A．To think about happy times.	B．To make many decisions at a time.
C．To stop feeling regretful about the past.	D．To learn about the process of decision-making.

【小題4】 Why are angry shoppers more likely to choose the first thing they are offered?

A．They often forget their past choices.	B．They make decisions without much thinking.
C．They tend to save time when shopping.	D．They are too angry to bargain.

【小題5】What do we learn from the text?

A．Emotions are a part of decision-making.

B．Sad people always make worse choices.

C．No emotion seems to help us make good choices.

D．Only sad feelings affect our thinking and motivation.

Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.
A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.
One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.
The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).
【小題1】What’s the main idea of the first paragraph?

A．Explaining why there is a lack of rain at times.

B．Introducing several different patterns of rainfall.

C．Telling us how to avoid problems caused by rain.

D．Giving the idea that there are ways to manage rain water.

【小題2】According to the second paragraph, “Rain Gardens" are likely to _____.

A．harm the environment in the short run

B．become popular over the next few years

C．be turned down by most new developments

D．be too expensive for common people to accept

【小題3】We can learn from the third paragraph that _____.

A．floods are often the results of small rains

B．a(chǎn) heavy rain is less difficult for plants to absorb

C．the rain garden helps send rainwater back into the air

D．larger amounts of rainwater flow straight off in city environments

【小題4】According to the last paragraph, what does the rain garden help to clean?

A．The plants

B．The ground.

C．The water.

D．The street.

B
What happens inside the skull of a soccer player when repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (腦震蕩) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外傷的) brain injury”, like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.
【小題1】The passage is most probably a ________.

You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.
【小題1】You can see the book because_______.

A．your eyes are close to it	B．it reflects some of the sunlight
C．it has light of its own	D．your eyesight can get to it

【小題2】The underlined word “l(fā)uminous” means_______.

A．visible

B．a(chǎn)ll colors

C．giving off light

D．sunlight

【小題3】________ have light of their own.

A．The sun and the moon	B．The stars and the earth
C．The sun and the stars	D．The moon and the earth

【小題4】Which of the following is true?

A．All the things you can see give off light.

B．Light from the book is much shorter than that from the moon.

C．The moment you open your eyes the light from the book travels to your eyes.

D．Light travels so fast that there is no time for you to read.

【小題5】This article is probably from _________ .

A．a(chǎn) science magazine	B．a(chǎn) medical magazine
C．a(chǎn) biography	D．a(chǎn) story book.

We use an average of 158 liters of water a day in Britain, for which we pay a bargain price of 28p a liter, but much of this is just cash down the drain, according to water companies.
Most are campaigning to cut the amount we use. And the frontline weapon in their campaign is the water meter (計(jì)量器). They want us all to have one and one company is seeking powers to make this compulsory.
The Government is anxious for us to use less water, too. Elliot Morley, the Environment Minister, says he is impressed by the savings when a meter is installed. In most homes, consumption drops by 20 percent.
He also thinks consumers get a good deal from meters. He said, “Most people would find that they would either be exactly the same or better off with water meters and it is a fairer way of paying for water.”
At present, only 25% of households have meters and most of those are in East Anglia. They are installed by water companies, and households then have about ￡43 added to each bill to cover the cost of installing and reading the meter.
Barrie Clarke, a spokesman for Water UK, said, “We want everyone to be more water wise—to think about the amount of water they use. But with our climate change and different weather patterns, over time it will make economic and environmental sense to think how we use water. This may mean meters.”
Mr. Clarke believes the easiest way to save water is to use less in the garden. In one hour, a sprinkler uses the same amount of water as the average family of four uses in a day—about 632 liters. He said that gardeners should water in the evening so that it dose not evaporate in the heat of the day and that every household should have a water butt to collect rainwater for use in the garden.
【小題1】Which of the following is NOT the advantage of installing water meters?

A．Water consumption drops.

B．It’s fairer to pay for water.

C．They’re installed for free.

D．People are more water wise.

【小題2】The passage implies that ________.

A．water meters are welcome by British people

B．people will be better off with water meters

C．everyone has become wiser to use water now

D．saving water is both good to economy and environment

【小題3】How many liters of water does an average family of four use in a day after installing a meter in Britain?

A．a(chǎn)bout 126 liters	B．a(chǎn)bout 158 liters
C．a(chǎn)bout 506 liters	D．a(chǎn)bout 632 liters

【小題4】The underlined word “evaporate” in the last paragraph means _________.

A．change into steam and disappears

B．a(chǎn)bsorb the heat of the day

C．sink into the soil

D．turn into ice

【小題5】According to Mr. Clarke, some good ways to save water are as follows EXCEPT ________.

A．using less on the garden

B．using a sprinkler

C．watering in the evening

D．gathering rainfall for garden use

Across countryside, non-food crops are growing alongside wheat．Some are used in new alternatives to plastics and other materials, but others will simply be burned．
Burning crops is becoming more popular because it is good for the planet．Doing so is also cheaper than burning fossil fuels．As more land is devoted to non-food crop production, the economics of crops for fuel are likely to become even more favorable．
Humans have been burning such biomass—organic materials from plants or animals— since they discovered fire．But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion．
Even allowing for emissions (排放) of carbon dioxide from fuel used in planting, harvesting, processing and transporting biomass fuel, replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90 percent．
Power stations around the world are experimenting with forms of biomass to add to their coal or oil, with encouraging results．Indeed, power companies could profit by turning to biomass, especially when the subsidies (補(bǔ)助) many governments offer for using renewable energy are taken into account．
Farmers can benefit from growing biomass．In Europe, the reduction of subsidies for certain crops is exposing farmers to market forces．Instead of being paid for whatever they produce, farmers must seek a clear demand for their product．Many believe that the demand for alternatives to fossil fuels could be just such a driver．
But while biomass offers a variety of potential alternatives, the world's infrastructure (基礎(chǔ)設(shè)施） has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted．
Also, there are problems with using biomass．Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment, few are built to run on biomass alone．Burning some forms of biomass also causes environmental problems．Oils and waste can be smelly, while wood produces smoke unless burned properly．
The supply chains for fossil fuels are set up well, but those for biomass are just the beginning. Sources of supply for biomass rely on farm production and can therefore be less reliable. They are necessarily limited and it wouldn't make sense to turn a very large amount of valuable agricultural land away from food crops．But as the world adjusts to the need to control greenhouse gas emissions, these problems may receive more attention．
【小題1】What do we know about biomass?

A．It is a useful way of burning crops．

B．It is plant and animal matter used to provide power．

C．It is a new alternative to be used widely．

D．It is a popular approach to fighting against pollution．

【小題2】What are the advantages of using biomass?
a．It gives off less greenhouse gases．
b．It helps farmers receive subsidies for what they produce．
c．It has met the clear demand for energy．
d．It has brought subsidies for some power companies．
e．It is cheaper than burning fossil fuels．

A．a(chǎn), b, c

B．b, c, d

C．c, d, e

D．a(chǎn), d, e

【小題3】For coal-fired power stations, ______．

A．more effective ways to use biomass have been tried

B．using renewable energy has become their daily task

C．burning biomass alone would require considerable changes

D．setting up dependable supply channels needs governments' support

【小題4】What is the author's attitude towards biomass fuels?

A．Defensive．

B．Doubtful．

C．Negative．

D．Objective

Back those photos up
The images were striking．Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions．
If that doesn't move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos．
Here is a brochure (手冊) on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad．
Scanning
The first step for those old photos is to scan them and save them to a digital format (格式)．Most，printers come with scanners these days, so that's an easy but extremely time-consuming step．
Storing the photos
With your scans in place, import the photos into your computer, and back them up．
You could make multiple copies of the disks and spread them to loved ones．Or you could choose external (外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer．
Online backup
If you need lots of space, look at a pure online backup service, Caronite．
Caronite backs up 300 million files daily．Once you sign up, it starts to pick up everything you have on your hard drive．But photo collection on your computer's main hard drive charges for $ 59 a year．
Cloud Storage
For folks who don't need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft's SkyDrive let you store files online by yourself, share and instantly access them．All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive．But if you want more, you need to pay．
Bottom Line
The hard drive or flash drive is the cheapest and easiest．But drives can fail．Online services are more expensive, but more secure．With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are．
【小題1】What can we know from the passage?

A．Scanning photos takes little time but costs a lot．

B．The hard drive or flash drive is the cheapest and safest．

C．Google Drive offers unlimited free photo storage on line．

D．Caronite charges for backing up photos from hard drive．

【小題2】Which of the following allows storing files automatically?

A．Caronite．

B．Dropbox．

C．SkyDrive．

D．Flash drive.

【小題3】The main purpose of the passage is to ______．

A．tell real stories about storage services

B．introduce some of the storage services

C．describe the functions of storage services

D．a(chǎn)rgue about the advantage of storage services
