It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”

You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不見(jiàn)的) blanket.

Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

In Japan, “what’s your type?” is much more than small talk; it can be a more important question in everything from matchmaking to getting a job. By type, the Japanese mean blood type, and no amount of scientific debunking (揭穿) can kill a widely held belief that blood tells all.

In the year that just ended, four of Japan’s top 10 best-sellers were about how blood type determines personality, according to Japan’s largest book distributor, Tohan Co. Taku Kabeya, chief editor at Bungeisha, thinks the appeal comes from having one’s self-image confirmed; readers discover the definition of their blood type and “It’s like ‘Yes, that’s me!’“

As defined by the books, type As are sensitive perfectionists but overanxious; type Bs am cheerful but weird and selfish; Os are curious, generous but stubborn; and Abs are arty but mysterious and unpredictable. All that may sound like a horoscope(占星), but the public doesn’t seem to care. Nowadays matchmaking agencies provide blood-type compatibility (兼容性) tests, and some companies make decisions about assignments based on employees’ blood types. Children at some kindergartens are divided up by blood type, and the women’s softball team that won gold at the Beijing Olympics used the theory to customize each player’s training.

Blood types, determined by the proteins in the blood, have nothing to do with personality, said Satoru Kikuchi, associate professor of psychology at Shinshu University. “It’s simply false science, “he said, “The idea encourages people to judge others by the blood types, without trying to understand them as human beings. It’s like racism.” This use of blood-typing has disreputable (名聲不好的) roots. The theory was imported from Nazi race ideologues (空談家) and adopted by Japan’s militarist government in the 1930s to breed better soldiers. The idea was abandoned years later and the craze faded. It resurfaced in the 1970s, however, as Masahiko Nomi, a supporter with no medical background, gave the theory mass appeal. His son, Toshitaka now promotes it through a private group, the Human Science ABO Center, saying it’s not intended to rank or judge people but to smooth relationships and help make the best of one’s talents.

1. That many Japan’s best-sellers were about blood type implies ____________.

A. this topic is used by many people in small talks

B. Japanese attach great importance to blood type

C. people don’t want to have confirmed self-image

D. the definition of blood type leads to arguments

2. According to the passage, ________ may face more pressure while performing a task.

A. type As   B. type Bs    C. type Os    D. type ABs

3. Kikuchi compared blood type determinism to racism because ______________.

A. both blood type and race are determined by the proteins in the blood

B. neither blood type nor race is related to our character and personality

C. both of them judge people without considering their individualities

D. blood type determinism believes human abilities are decided by race

4. Who introduced the blood type theory to Japan?

A. Nazis from Germany.                                  B. Japan’s militarist government.

C. A supporter called Masahiko Nomi.         D. Human Science ABO Center.

【小題1】 In most scientists’ opinion, the global warming is mainly caused by ________.

It may not be news to parents of teenage girls, but researchers have confirmed that no one can stop their 16-year-old daughter from deciding how the family spends its money.

The willpower and determination of teenage girls give them a big say in how a family’s money is spent on everything from food and meals to mobile phones, and, of course, clothes. Teenage boys did not show up at all in the analysis, which was designed to find out the influence of young people on household spending.

The findings on the spending power of teenage girls were calculated from Office for National Statistics records of family spending during the 1980s and 1990s. Researchers examined how much money went on services and leisure goods in different kinds of homes. They checked spending on food, restaurant meals, alcohol, tobacco, services, heating, transport, clothes and sports in 2,745 British families.

They found that teenage girls in the UK typically played an active role in family decisions about the allocation（分配）of household resources. But older children— those over the age of 21 who are still living with their parents—appear to have no say in household decisions.

They also tried to calculate to what extent the bargaining power of a teenager affected family budgets. “Every parent knows that children, even at a very early age, have their own preferences with regard to consumption, researchers said. “But children are only interested in a limited range of goods—mainly sweets and toys—and parents are able to use punishment to reduce their children’s bargaining power or remove it.”  When they become teenagers, however, girls are much more independent and they are capable of earning their own money, which improves their bargaining power in family decisions.

The researchers could not explain why girls have more influence over spending while the evidence for boys is much less conclusive. However, this study could be of great significance to market research and how marketers target children.

1. From the passage we can learn that            .

2.What does the underlined part “give them a big say” in the second paragraph mean?

3.It appears that household decisions are NOT affected by        .

4.How can parents reduce children’s bargaining power?

Exposure to environmental tobacco smoke (ETS)-also called “second-hand smoke” and “passive smoking” contains over 4 000 chemicals, including over 50 known carcinogens (致癌物) and many poisonous things. No safe level of ETS exposure has been proved. Nor is there any expectation that further research will identify such a level.

Several recent reviews have confirmed the serious risks to health and life associated with passive smoking. Long time exposure to second-hand smoke has been proved as a cause of many of the same diseases caused by active smoking, including lung cancer, cardiovascular (心臟血管的) disease, and childhood disease.

Living with a smoker has been shown to increase the risk of coronary heart disease (冠心病) among non-smokers by 25-30% (a recent study indicates that this figure may actually be higher). There is also growing evidence that passive smoking is causally linked to stroke in non-smokers, although further research is needed to estimate the risk.

Second-hand smoke is especially dangerous for young children and infants, being associated with sudden infant death, pneumonia, bronchitis (支氣管炎), asthma (哮喘) and respiratory symptoms as well as middle ear disease. ETS exposure in pregnant women can cause lower birth weight, foetal (胎兒的) death and preterm delivery.

Most of the adverse health outcomes brought about by ETS show that the risk increases steadily with increasing exposure. The level of individual risk is lower compared to active smoking. Nevertheless, the fact that large numbers of people are exposed results in a substantial burden of disease.

    Action on smoke-free environments would not only protect people from the harm of ETS exposure but also contribute to the reduction of tobacco consumption in the whole population. The health effects of reduced passive and active smoking would include reduced illness and death from major disease types-in particular lung cancer, coronary heart disease, and stroke-and increased life expectancy.

51. Which of the following statements is true? _______

  A. Although ETS contains many harmful things, it is not unsafe.

  B. The fact that second-hand smoke is safe has been recently found.

  C. It is expected that further research will be done to test the level of ETS.

  D. By far the safe level of ETS has not been found and will not in the future.

52. Cardiovascular disease can be caused by _______.

   A. long time passive smoking    B. accidental active smoking

   B. occasional passive smoking   D. short term active smoking

53. According to the article, the statements about the risk of coronary heart disease are wrong EXCEPT that________

A. if you smoke, the risk of this disease will increase by 25-30%. 

B. the non-smokers exposed to smoke will increase the risk of this disease by 25-30%.

C. for the smokers, the risk of getting this disease is higher than that of the non-smokers.

D. the non-smokers exposed to smoke will be more easily to get this disease than the smokers.

54. What does the underlined word “delivery” mean? ________.

   A. Transferring to another     B. Giving birth   C. Throwing away   D. Giving out

55. What’s the author’s main purpose in writing this passage? ______

   A. To introduce what is ETS.

   B. To tell the readers how to avoid ETS.

   C. To call for the action against ETS.

   D. To warn the readers against smoking.

Iodine (碘）– rich salt was the hottest item on Chinese shelves Thursday, being snapped up (搶購(gòu)) by shoppers after rumors spread that iodine intake could help protect one’s body from radiation damage, although the authorities have confirmed that the nuclear crisis in Japan had not affected China.
Rumors also spread about radioactive substances being leaked into ocean water that could pollute Chinese coasts.
The crazy buying has occurred nationwide, from the supposedly easily – harmed eastern coastal provinces to regions far – inland such as Xinjiang.
Supermarkets and convenience stores began reporting the lack of salt stocks from early Wednesday, with all salt sold out at many Carrefour and Wal – Mart stores. Some online clothes stores have begun offering salt as a bonus to customers.
Relevant government departments were trying hard to stop this round of panic – buying.
The Ministry of Health deniedthe rumor that eating more iodine – rich salt could repair damage from radiation, saying that it is technically impossible to absorb enough iodine for radiation prevention from eating salt.
The government urges the local market authorities to keep all salt sellers in check and to prevent storing and overpricing.
Also the spokesman of the government said that China’s seawater, as a source of salt, would not be affected by the nuclear crisis, as it would be impossible for radioactive substances to reach Chinese waters via the eastward ocean current.
“Reasons behind the salt rush include unclear information on the development of the nuclear crisis and terrifying media reports of the severity of a possible complete meltdown. If the fear of a Chernobyl – like catastrophe cannot be ended, the crazy buying will likely continue,” said a professor from Beijing University.
Beijing urged Tokyo Thursday to better release information at the Fukushima plant.

Mars Was Not Always Bitterly Cold
Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today.  The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented.
The Caltech scientists say carbonate（碳酸鹽） minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite（隕石） that had its beginnings near the Martian surface.
Today, the average temperature on Mars is sixty-three degrees below zero Celsius.
The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information.
Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth.
The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home."
【小題1】 The underlined word “establish” in Paragraph 1 probably means “___________”.

Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming. Countless recent reports from the world’s leading scientific bodies have said the same thing. For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity.”
The idea that humans could change the planet’s climate may be counter-intuitive(與直覺(jué)不符的), but the basic science is well understood. Each year, human activity causes billions of tons of greenhouse gases to be released（釋放）into the atmosphere. As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.
Of course, the planet’s climate has always been changing thanks to “natural” factors(因素) such as changes in solar or volcanic（火山的）activity, or cycles relating the Earth’s going around the sun. According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question. As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide（二氧化碳）and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

Exposure to environmental tobacco smoke (ETS)-also called “second-hand smoke” and “passive smoking” contains over 4 000 chemicals, including over 50 known carcinogens (致癌物) and many poisonous things. No safe level of ETS exposure has been proved. Nor is there any expectation that further research will identify such a level.
Several recent reviews have confirmed the serious risks to health and life associated with passive smoking. Long time exposure to second-hand smoke has been proved as a cause of many of the same diseases caused by active smoking, including lung cancer, cardiovascular (心臟血管的) disease, and childhood disease.
Living with a smoker has been shown to increase the risk of coronary heart disease (冠心病) among non-smokers by 25-30% (a recent study indicates that this figure may actually be higher). There is also growing evidence that passive smoking is causally linked to stroke in non-smokers, although further research is needed to estimate the risk.
Second-hand smoke is especially dangerous for young children and infants, being associated with sudden infant death, pneumonia, bronchitis (支氣管炎), asthma (哮喘) and respiratory symptoms as well as middle ear disease. ETS exposure in pregnant women can cause lower birth weight, foetal (胎兒的) death and preterm delivery.
Most of the adverse health outcomes brought about by ETS show that the risk increases steadily with increasing exposure. The level of individual risk is lower compared to active smoking. Nevertheless, the fact that large numbers of people are exposed results in a substantial burden of disease.
Action on smoke-free environments would not only protect people from the harm of ETS exposure but also contribute to the reduction of tobacco consumption in the whole population. The health effects of reduced passive and active smoking would include reduced illness and death from major disease types-in particular lung cancer, coronary heart disease, and stroke-and increased life expectancy.
