3．Now scientists believe that global warming affects hibernating animals，causing them to wake up earlier．While this may seem a little concern，it is in fact a serious environmental problem．The shortened hibernation period could actually lead to significant decreases in the population of several species．
Some of the first evidence of the problem came from Colorado，where researchers at the Rocky Mountain Biological Lab have been observing marmot （旱獭） hibernation behavior since the 1970s．In the early days of their studies，marmots generally hibernated several weeks into the month of May．Nowadays，however，temperatures in the area have risen by 2.5degrees Fahrenheit，and the marmots wake up about a month earlier．
At least the marmots are still hibernating．Several other animals have not been hibernating at all recently．Brown bears in the Spanish Cantabrian Mountains did not hibernate last year．Chipmunks （花鼠） in the US and some snakes in Australia also skipped the hibernation period．The bears seem to have survived without losing many individuals．The chipmunks and snakes，however，were not so lucky．Many of the animals died of starvation during the winter．
The problem with animals waking up early，or skipping hibernation altogether，lies with the creatures'metabolism （新陈代谢）．When the animals hibernate，their metabolism drops significantly．The animals'heart rate slows，and they require very little energy to live．When the animals awake in the spring，their metabolism returns to normal．
But while their metabolism may be as active as it was before hibernation，food sources aren't as available as they were before．A marmot may wake up when temperatures get warmer，thinking it's spring，but plants will not have got the amount of sun they need to grow．So until the plants grow，the marmots have no reliable food source．
Many scientists believe the problem will continue to get worse．For many biologists，that's a scary prospect．Terry Root，an animal expert at Stanford University，said，"I do think what we will be facing is the extinction of many species．"

32．What is the viewpoint of the writer？B
A．Global warming will continue to get worse as time goes on．
B．Waking up early in spring may lead to the extinction of some animals．
C．Shortened hibernation will definitely decrease the population of animals．
D．Animals which do not hibernate die of starvation．
33．The writer sets the example of the marmot in order toA．
A．indicate that global warming influences animals'hibernation
B．explain that the weather gets warmer and warmer now
C．show that the weather in the United States is quite different
D．say some animals do not hibernate now due to warm weather
34．Judging from recent observation，which of the following animals suffered the LEAST from shortened hibernation？A
A．Brown bears．
B．Marmots．
C．Some snakes in Australia．
D．Chipmunks in the US．
35．Why can't marmots find enough food when they wake up？D
A．Because there are too many marmots in the wild now．
B．Because more and more animal species skip hibernation now．
C．Because winter days end much earlier than before．
D．Because plants haven't received enough sunlight for spring growth．

1．At the age of sixteen，I joined a volunteer group with my dad．I went on my first volunteer project in West Virginia．On the night we arrived，we discovered that"our family"was living in a trailer （拖车） that was in poor condition．Some people had been working on it for two weeks，but every time they finished one problem，another appeared．
We decided the only reasonable solution was to build a new house-something unusual but necessary under these circumstances．The family was overjoyed with their house that was twenty by thirty feet with three bedrooms，a bath and a kitchen．
On Tuesday of that week，while we ate lunch together，I asked the family's three boys，Josh，Eric and Ryan，"What do you want for your new room？"Expecting toys that children usually ask for，we were astonished when Josh responded，"I just want a bed．"
The boys had never slept in a bed!They were used to plastic mats （垫子）．That night we had a meeting and decided that beds would be the perfect gift．On Thursday night，a few adults in our group drove to the newest city and bought beds and new bedding．
When we saw the delivery truck coming，we told the family about the surprise．We could hardly contain ourselves．It was like watching excited children on Christmas morning．
That afternoon，as we fitted the parts of the beds together，Eric ran into the house to watch us and observed with wide-eyed enthusiasm from the doorway．As my father put a pillowcase （枕套） onto one of the pillows，Eric asked，"What is that？"
"A pillow，"he replied．
"What do you do with it？"Eric continued to ask．
"When you go to sleep，you put your head on it，"I answered softly．Tears came to my eyes as my father handed Eric the pillow．
"Oh…that's soft，"he said，hugging it tightly．
Now，when my sister and I start to ask for something that seems urgent，my dad gently asks，"Do you have a pillow？"
We know exactly what he means．

21．The writer's first volunteer project wasB．
A．working on a poor trailer
B．helping a poor family
C．donating beds and bedding

B．he expected to get some toys
C．he didn't know what a bed was
D．the boys had no bed to sleep in
23．From the passage，we can learn that Eric had never seenC before．
A．a trailer  B．a truckC．a pillow  D．a house
24．By saying"Do you have a pillow？"，the writer's father means thatA．
A．what they want to get may be unnecessary
B．they should not waste money on small things
C．they should do more volunteer work for the poor

17．Emily：My colleagues say I should get health insurance．（61）Whatdo you think of this suggestion，Paul？
Paul：I think it's really necessary，Emily．Though you have to spend some money，it saves money in the long term．（62）Besides，we may fall ill at times．I will give you my insurance agent's business card if you want．
Emily：In Germany，we have a national program，（63）providing（provide） all citizens with free health insurance．But here you have nothing．
Paul：Yes，I know．Many countries have national health insurance．America doesn't．
Emily：Why？As（64）faras I know，the US is the richest and （65）most powerful（powerful） country in the world，isn't it？
Paul：Well，（66）influenced（influence） by America culture，we think private companies can do things better（67）thanthe government．So we rely on private companies for insurance．
Emily：But isn't that expensive？
Paul：You're right．The health system（68）has been criticized（criticize） by many people over the years．They say it is not fair to poor people．
Emily：But what's your opinion？
Paul：Personally，a good body is more reliable than health indurance．That's（69）whyI set aside some time for exercise every day，（70）howeverbusy I am．

16．To live a long life，we've been told to eat well，exercise and manage stress．Now an eight-decade study indicates that is only part of the story．Health scientists Friedman explains some secrets to longevity（长寿） in the Longevity Project．
Friedman drew upon the work of Stanford University psychologist Lewis Terman，who began the study in 1921．Terman selected about 1，500 of the brightest boys and girls that he could find and tracked them throughout their lives．He died in 1956，but the project was carried on by others．Friedman took over the work in 1990 and used the data gathered for decades to better understand health and longevity．
"Genetic factors offer part of the explanation for why about one third of the people are more exposed to diseases and live shorter lives，"says Friedman．"But there's much more to that．"
Take character for example．Cheerful and optimistic children are actually less likely to live long lives．"The most cheerful and optimistic kids grew up to take more risks，"explains Friedman．"They tended to be smokers or heavier drinkers，and their hobbies were riskier．"
Often，with responsibility come stress．But some stress is not necessarily a bad thing，says Friedman．Actually，when the participants found meaning in their stressful jobs，they were committed to them and stress didn't hurt them．They thrived（茁壮成长） in spite of---or perhaps with the aid of---it．
Friedman also found that the conventional wisdom about fitness isn't quite right．If we try too hard to push ourselves into exercise，it can fail．Physical activity is important，they found，but it's more about doing what you love than sticking filmly to a certain fitness program．
And for adults who have fallen into long-sitting lifestyles，it's not too late．"if you can pick up an activity that you like---you don't have to go to the gym every morning---that really has a big impact on the rest of your life，"says Friedman．
33．Which of the following is NOT true about the Longevity Project？A
A．It has lasted for eight decades．
B．It was started by Terman in 1921．
C．It paused for a while after Terman's death．
D．About 1，500 boys and girls took part in the study．
34．If you want to join a fitness program，you'd betterD
A．stick firmly to it
B．try to exercise as hard as you can
C．ask other people to do it with you
D．choose whatever you really enjoy
35．Accoding to Friedman，D．
A．cheerful and optimistic children tend to live longer
B．taking up stressful jobs is always bad for people's longevity
C．it's impossible for adults with long-sitting lifestyles to live longer
D．genetic factors are not the only reason for people's getting diseases．

15．Here is an amusing story between a teacher and his student．The teacher（61）teaching（teach）math to his five-year-old student asked him，"If I give you one apple and one apple and one apple，how many apples will you have？"Within a few seconds，the student （62）replied（reply）confidently，"Four!"The teacher had expected a correct answer，（63）butshe was disppointed．She repeated the question，but the student still made the wrong answer after calculating on（64）hisfinger．
The（65）disappointment（disppoint） stayed on the teacher's face．She remembered that this student liked the stawberry．She asked，"If I give you one stawberry and one stawberry and one stawberry，how many will you have？"
The boy calculated carefully again，There was no press on him，but a little on his teacher（66）witha smile，the student said，"Three．"The teacher now had a（67）satisfied（satisfy）smile．So once again，she asked him，"Now，if I give you one apple and one apple and one apple，how many will you have？"
The student answered，"Four!"
The teacher became impatient，"Why my boy，why？"
In a low voice，the young student replied，"（68）BecauseIalready have one apple in my bag．"
When someone gives you an answer（69）that/whichis different from what you expet，don't think they are wrong．There may be an angle that you have not understood（70）atall．Therefore，you will have to listen and understand．

14．Most children now chat daily either online or through their mobile phones．They are connecting to a huge number of other children all over the world．Some are shy"in real life"but are confident to communicate with others online； others find support from people of their own age on relationship issues，or problems at home．
    Sometimes the online world，just like the real world，can introduce problems，such as arguments．Going online is great fun，but there are also a few people who use the Internet for offensive （冒犯性的） or illegal aims．Children must be made aware of both the good things and the dangers．
    To keep children safe your management must cover the family computer．Just as you decide which TV programs are suitable，you need to do the same for the websites and chat rooms your children visit．Remind your children that online friends are still strangers．Reminding them of the risks will keep them alert （警惕）．
    Computer studies are part of schoolwork now，so it's likely that your children may know more than you do．We get left behind when it comes to the latest gadgets and the interactive areas of websites，like chat rooms and message boards，which are especially strange．The language of chat is strange to many parents，too．Chatters love to use abbreviations （缩写） such as：atb-all the best，bbfn-bye bye for now，cul8er-see you later，gr8-great，Idk-I don't know，imbl-it must be love，kit-keep in touch，paw-parents are watching，lol-laugh out loud，xlnt-excellent!
