12．A single night of taking the drug Ecstasy （搖頭丸） can cause serious brain damage and speed up the start of Parkinson's disease，scientists say．Just two or three Ecstasy tablets can permanently destroy brain cells that affect movement and reasoning，according to American research that links the drug to Parkinson's for the first time．
A study by a team at Johns Hopkins University in Baltimore，Maryland，involving squirrel monkeys and baboons （狒狒） found that both species suffered permanent damage to key cells，which are lost in Parkinson's，after receiving three low doses（劑量）of Ecstasy at three-hour periods．
The study is particularly important because baboons are one of the best animal models for the human brain．George Ricaurte，who led the research，said that the widespread abuse of drug might have caused severe damage．"The most troubling result is that young adults using Ecstasy may be increasing their risk of developing Parkinsonism as they get older．"
Alan Leshner，a former director of the US National Institute on Drug Abuse，said，"This study emphasizes the multi-aspect damage that Ecstasy causes to users．We've long known that repeated use damages brain cells．But this study shows that even very occasional use can have long-lasting effects on many different brain systems．It sends an important message to young people：don't experiment with your own brain．"
Janet Betts，a mother whose teenage daughter Leah died after a single Ecstasy tablet in 1995，said，"This comes as no surprise．But people can't see the effects at first，and they say it won't happen to them．We'll see the symptoms later，just as we have with smoking．"

A．explain the bad effects of drugs on people's health
B．warn young people of the risk of taking the drug Ecstasy
C．persuade people out of such bad habits as smoking and using drugs
D．tell us the links between the drug Ecstasy and Parkinson's disease

A．won't cause serious brain damage
B．can permanently destroy one's brain cells
C．will result in immediate symptoms
D．may bring on Parkinson's at once
65．Why are squirrel monkeys and baboons involved in the experiments？A
A．Because their brain is similar to human being's．
B．Because these animals usually take drugs．
C．Because these animals will soon get well after the experiment．
D．Because there is a model in the animals'brains．

A．Leah died after a single Ecstasy tablet in 1995
B．taking drug has the same symptoms as smoking
C．occasional use of the drug can have long-lasting effects on the brain systems
D．people have long known that repeated use of the drug damages brain cells．

11．One Monday morning，the class were excited about the rumor that the science room was on fire over the weekend．Mr．Johnson，my fifth grade teacher（36）Cnd explained that science class would be cancelled due to the （37）AHe also warned us not to go near the room（38）Bit could be dangerous．

10．A．Don't assume that the sticker price is the purchase price．
To get the lowest price，go in with a starting price that's based not on the sticker price but on how much the dealer paid for the vehicle．A reasonable price to start negotiations is either 4 to 8 percent over what the dealer paid or the CR Wholesale Price，depending on the demand for the model．
B．Do your homework．
Thoroughly research your choices．Read a variety of reviews．Check the reliability，safety，fuel economy，and pricing of any models you're considering．And don't wait until the day you plan to buy to test drive the vehicles．If you have a trade-in，know its approximate worth．That will depend on the vehicle's age，condition，mileage，and equipment，as well as where you trade it in．
C．Negotiate one thing at one time．
        Make clear that you want the lowest possible mark-up over your starting price．Add that you intend to visit other dealerships selling the same vehicle and will buy from the dealer with the best price．Only after you've settled on the price should you discuss financing，leasing，or a trade-in，as necessary．Negotiate each item individually．Remember，you're in charge and can leave at any time．Heading for the door can sometimes jump-start a slow-moving negotiation or bring a lower offer．
D．Don't pay for extras you don't need．
        Don't accept those unnecessary services and fees．If the items are on the bill of sale，put a line through them．Vehicle bodies are already coated to protect against rust．And CR reliability survey show that rust is not a major problem with modern cars．You can treat upholstery and apply paint protectant yourself with good off-the-shelf products．You can do your own VN etching with a kit that costs about $25．
E．Other costs．
In addition to the vehicle price，you need to consider other costs，including：Sales tax； Registration fees； Insurance premiums Taxes and registration fees can increase your out-of-pocket cost by as much as 10 percent or more，and driving a car that's worth more than your current one will cost more to insure．Be sure to check with your insurance agent or get insurance quotes online so you understand what you're getting into．
F．Arrange financing in advance．
Compare interest rates at several banks，credit unions，and loan organizations before checking the dealer's rates．If pre-approved for a loan（貸款），you can keep financial arrangements out of the negotiations．Automakers may offer attractive financing terms，but make sure you qualify for them．
 
請結(jié)合以上建議，與下面的情形進(jìn)行匹配．
46．Many dealerships prey on the unprepared．Going into a showroom"cold"--without having gathered key facts and preliminary（初步的） pricing figures--gives the salesperson too much control over the buying process．B
47．The dealer invoice price is commonly available on Web sites and in pricing guides．But the invoice price isn't necessarily what the dealer paid．There are often behind-the-scenes bonuses（幕后紅利），such as dealer incentives（獎(jiǎng)勵(lì)） and holdbacks，that give the dealer more profit margin（空間）．A
48．Salespeople like to mix financing，leasing，and trade-in negotiations together，often asking you to negotiate around a monthly payment figure．This tactic（策略） gives the dealer more latitude to offer you a favorable figure in one area while inflating（抬高）figures in another．C
49．The salesperson may try to sign you up for a higher interest rate than you could get elsewhere．F
50．Dealers often try to sellyou extras such as rust proofing，fabric protection，and paint protection or push etching your Vehicle Identification Number on windows to deter thieves．D．

（71）BPeople traveled in search of food and shelter or in order to flee from their enemies．Sometimes they were looking for gold or silver in order to become rich．On other occasions they were searching for rich farmland．
This is not to say that no one ever traveled just for fun．Even in ancient times，some pleasure travel occurred．During a typical season，700，000 tourists would crowd into the ancient city of Rome，where animals performed and magicians entertained them．（72）E
（73）F International tourist arrivals alone reached as many as 546 million in 1994 and are forecast to rise to 937 million in 2010，according to the World Trade Organization．
（74）AProbably the most common reason for traveling is related to our physical well-being．Actually，traveling to sports events is one of the fastest growing types of travel．In our fast developing society where stress has become part of people's life，people can rest and relax by having a change of environment and activities．
（75）G No one seems to doubt that travel broadens the mind．In 18 th century Europe，young men would go on a Grand Tour to various countries in order to complete their education．Today the desire to travel to different countries is encouraged by modern mass media．People who travel to other countries can at the same time learn more about their own country and culture．

A．But why do people like traveling so much？
B．Throughout history，most travel was not for pleasure．
C．So they travel to a lake for a swim or to a park for a hike．
D．The improvement in transportation has also encouraged people to travel．
E．People had appeal to their lives in the past．
F．The growth of tourism has become a modern phenomenon experienced by all countries in the world．
G．Another important reason for traveling is to satisfy our curiosity about different places and cultures．

8．

A．Train conflict-management B．Teach mutual respect C．Guide children by personal examples D．Recognize the existence of sibling conflict E．Show appreciation for who your child is F．Do not play favorites

76．Sibling conflict is as old as Cain and Abel，as legendary as Cinderella and her stepsisters and can be as deadly as the daughters of King Lear．Parents should know the battles are inevitable and must prepare their kids to defuse potentially ugly situations．And there will be times when parents must come to a child's defense and say，"We are family，and we will not say anything that doesn't build up one another．We will respect each other．"Use following tips for encouraging kindness in the home：D
77．Do not allow your children to insult one another．Words are extremely powerful，and snide comments can damage deeply．Experts say every negative comment needs at least five positive remarks to even out．Teach your children to be kind and to appreciate each other．Encourage your  kids to see each other's talents．Through recognizing these unique strengths，they will be able to work together well．B
78．Sibling rivalry usually originates from a child feeling that the other sibling is loved more，and in some cases when parents are being substantively unfair or show favoritism toward one child，this indeed may be the problem．In Genesis，we see the damage done by Jacob's favoritism of Joseph．Remember that all children are created equal，but not all children are the same．Recognize and praise each child's individual skills，strengths and accomplishments without implying that one child is somehow better．Be sure each child receives adequate parental interest and quality time．F
79．Do not deny your child's feelings，but help him learn to express emotions in an appropriate way．If you see your child acting jealously，encourage him to identify the emotion by saying，"I understand that you feel bad because…"or"I know you hurt because…"Helping your children figure out the causes of their actions will help them learn how to deal with problems in the future．A
80．Most parents realize children imitate what they see，so look at the example you set．Do you compete with your siblings？Or do you consistently show kindness to your brothers and sisters？By checking your actions，you can be better prepared to show your children how to emerge the best of friends following the inevitability of a little sibling conflict．C．

7．Several years ago，while attending a communication course，I experienced a most unusual process．The instructor asked us to （36）B anything in our past that we felt （37）Aof，regretted or incomplete about and read our lists aloud．
This seemed like a very （38）Aprocess，but there's always some （39）Dsoul in the crowd who will volunteer．The （40）Cthen suggested that we find ways to （41）Cto people，or take some action to right any wrong doings．
Then the man （42）Ame raised his hand and volunteered this story：
"There was a sheriff（治安官） （43）Cof us kids liked．One night，my two friends and I decided to play a （44）Con him
"After drinking a few beers，we climbed the tall water tank in the middle of the town，and （45）Bin bright red paint：SHERIFF BROWN IS A S．O.0．B．（畜生）．The next day，almost the whole （46）Bsaw our"glorious sign．Within two hours，Sheriff Brown had us in his office．My friends told the truth but I （47）D．No one ever found out．
"Nearly 20years later，Sheriff Brown's （48）Aappeared on my list．I didn't even know if he was still （49）D．Last weekend，I managed （50）Bto him by phone and said，‘I want you to know that I did it．'
"‘I knew it!'he yelled back．
"We had a good （51）Dand a lively discussion．His dosing words were：‘Jimmy，I always felt （52）Dfor you because your friends got it off their chest，（53）Ayou were carrying it around all these years．'"
Jimmy inspired me to （54）Call the 22items on my list within two years'and I al-ways remember what I learned from the （55）C：It's never too late to right the past wrongdoings．

C．Do a good workout．
D．Keep a good memory．
E．Use logic and reasoning skills．
F．Build up language skills．

Many men are devoted to exercise to build up their bodies，but the phrase"use it or lose it"applies to more than just the muscle in our bodies-it also applies to our brains．Here are 5tips that can help our brains stay sharp．
（76）D
It plays an important role in all cognitive activities，including reading，reasoning and mental calculation．There are several types of its work in the brain．Taken together，these are the cognitive skills we may notice most when they begin to fail．To keep a good memory，you need to train for it，which can be easier than you think．Listening to music is enjoyable．By choosing a song you don't know and memorizing the lyrics，you improve your memory skills．
（77）B
It is necessary in nearly all daily tasks and it enables you to focus despite noise and to think about several things at once．We can improve the skill by simply changing our routines．Change your course to work or reorganize your desk-both will force your brain to wake up and pay attention again．
（78）F
It will increase your ability to recognize，remember and understand words．With regular practice，you can expand your knowledge of new words and more easily think of words to say because they will come to you more naturally．For example，if you usually only read the sports section，try reading a few business articles．You'll learn new words，and by using them you can also exercise your brain．
（79）A
You can also exercise your brain by taking advantage of your environment．Try walking into a room and picking out five items and their locations．When you exit the room，try to remember all five items and where they are located．Too easy？Wait two hours and try to remember those items and their locations．Analyzing what you saw will force you to use your memory and train your brain to focus on your surroundings．
（80）E
It helps you make decisions，build up hypotheses and consider the possible consequences of your actions．Activities in which you must define a strategy to reach a desired outcome and calculate the right moves to reach the solution in the shortest possible time are actually fun activities you can do daily．For example，playing video games requires you to come up with a strategy so as to advance to the next level．

A．The future cars and environmental protection B．Driving experience in electronic control C．The functions of self-driving system D．Ways of better safety in the future E．The combination of computing and communications in future cars F．Wireless communications

76．E
Today，the Internet is in a few cars； tomorrow，broadband （寬帶） will be in all of them．Any capability a personal computer has，a car will have，including two-way wireless communications for receiving e-mail，music，and movies．When you're crossing the lonely place，the kids can watch TV if they're bored．Every passenger will have a video feed．
77．C
Every car will have a self-driving system linked to GPS satellites．Radar sensors （傳感器） will track nearby cars．On the freeway，they'll slow your car when the car ahead of you slows； in town，they'll help you park without hitting other cars．At rush hour，you'll get the routes around traffic jams and accidents．The self-driving system in a car makes it possible for the car to drive itself，though some scientists say that's 30to 40years off．
78．A
Motor vehicles today represent 20to 30percent of the world's energy use．In the near future，a small gasoline engine and an electric motor will be brought together．Drivers will use electricity in a storage battery for short distances．Longer term，cars might burn hydrogen or use a fuel cell that converts a fuel like hydrogen and combines it with oxygen to create power．Then the waste will be pure water．
79．B
You'll use the voice control："Make it a bit cooler"or"find me country music"．Lighter，more reliable electronic controls replace mechanical controls．Fiber optics （光纖） replace electrical wires and light bulbs．Seats will be air-conditioned．The car will travel with one side higher than the other when turning，just as an airplane does now．
80．D
Cars will avoid some accidents by maintaining safe following distances，and by sensing sleepy or drunk drivers．Air bags will adapt for every passenger according to their size，weight，and position in case accidents happen．

A．What does the Olympic Motto mean？ B．Research on individual styles improves performance． C．Research holds the key to success． D．Personalized programs will help． E．New equipment has made a difference． F．Is there a limit to record-breaking？

76．F
A world record is every athlete's dream，but the hard-won records of a few years ago are mostly just today's qualifying times．Roger Bannister's famous four-minute mile of 1956has been beaten by nearly 15seconds，while almost an hour and twenty minutes has been taken off the women's marathon since.1953．‘Faster，higher，stronger'，is the Olympic motto，and today's competitors continue to push back the boundaries of what the body can achieve．But one wonders if this can continue．
77．E
The last forty years have seen many important technological advances．For example，since the introduction of strong flexible，fiberglass poles，over a meter has been added to the pole vault record．There have also been important developments in the design of the running shoe．And while a shoe won't actually make someone run faster，modern shoes do mean many more miles of comfortable，injury-free training．
78．C
Pushing back the limits now depends more on science，technology and medicine than anything else．Athletic technique，training programmes and diets are all being studied to find ways of taking a few more seconds off or adding a few more centimetres to that elusive world record．It seems that natural ability and hard work are no longer enough．
79．B
The research to find more efficient ways of moving goes on．Analysis of an athlete's style is particularly useful for events like jumping and throwing．Studies show that long jumpers need to concentrate not on the speed of approach，as once thought，but on the angle their bodies make with the ground as they take off．However，the rules governing each sport limit advances achieved by new styles．For instance only one-footed takeoffs are allowed in the high jump．

In the future，it should be possible to develop a more individual approach to training programmes．Athletes will keep detailed diaries and collect data to help predict the point when training becomes overtraining，the cause of many injuries．If athletes feed all their information into a database，it may then be possible to predict patterns and to advise them individually when they should cut．

3．The Entropia Universe
The Entropia Universe is a virtual world on the Internet，which seems very like our real life．It is set in a distant future and based on a planet called Calypso．Entropia was the brainchild of a group of Swedish computer lovers who decided to see if they could create a three dimensional （維度的） virtual world that could be placed on the Internet．They did manage after they received the financial backing they needed．
The game can be played for free，but nearly all in-game activities require personal resources that you have available to use．Although there are various activities to keep you busy on Calypso，what most people do first is to find themselves a profession，such as hunting the fierce animals on Calypso，mining the precious minerals and making tools．Then they can think about buying their virtual house or paying a visit to a virtual nightclub or doing any of the other activities that make life bearable．
Entropia has its very own economy （經(jīng)濟(jì)） and its own currency，the PED （Project Entropia Dollars）．Players move real world money into PED which they then use to pay for their life on Calypso．However，the virtual things inside Entropia do have a real value in the outside world，and careful business deals mean that players can actually make real money there．PED can be changed into dollars any time at a rate of 10PED to 1US﹩．
What's so impressive about The Entropia Universe is the number of players； currently more than 600，000 representing over 220 countries from planet Earth．A number of players insist that it's a good way to make money．However，the reality of Entropia's economic system is that most people end up paying more than they earn and it's not uncommon to find players who are paying up to﹩200 a month into their PED account．This might not be the most economical way of spending one's free time．However，some people say that for them the fact that they can escape the realities of the earthbound life and become a different person with a completely different life for a few hours every week is worth the use of money，even if they don't get any interest rates on it．
