17．Many teenagers feel that the most important people in their lives are their friends．They believe that their family members，especially their parents，don't know them as well as their friends do．In large families，it is often for brothers and sisters to fight with each other and then they can only go to their friends for advice．It is very important for teenagers to have one good friend or many friends．Even when they are not with their friends，they usually spend a lot of time talking among themselves on the phone．This communication is very important in children's growing up，because friends can discuss something difficult to say to their family members．
However，parents often try to choose their children's friends for them．Some parents may even stop their children from meeting their good friends．The question of"choice"is an interesting one．Have you ever thought of the following questions？
Who choose your friends？
Do you choose your friends or your friends choose you？
Have you got a good friend your parents don't like？
Your answers are welcome．

分析 文章講述了青少年要擁有自己的朋友這是很重要的，朋友間彼此了解，可以互相討論事情，作為父母應(yīng)該要了解孩子們．

解答 29-----31 ADC
29  A．細(xì)節(jié)理解題．文章的第1句 Many teenagers（青少年） feel that the most important people in their lives are their friends 告訴我們，青少年認(rèn)為對(duì)他們而言最重要的人是朋友，即選項(xiàng) A 所說(shuō)的內(nèi)容． 
30  D．細(xì)節(jié)理解題．由第2段的第2句 Even when they are not with their friends，they usually spend a lot of time talking among themselves on the phone 可知，青少年即使獨(dú)處，也會(huì)打電話與朋友交流，因此選 D．
31  C  推理判斷題．根據(jù)全文我們可以推斷出青少年對(duì)朋友的依賴太重，而與父母相處的時(shí)間太少，因此文章建議父母應(yīng)多了解子女，所以選項(xiàng) C 最符合題意．

點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．

8．Scientists fear rising energy bills may lead to an increase in obesity （肥胖） after discovering a link between poorly-heated homes and higher body-fat．
Researchers from the University of Stirling's Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter．Instead，the team found that people who live in well-heated homes are more likely to have low body mass index （體重指數(shù)） levels while those who keep their heating turned down or off tend to be heavier．
Dr Michael Daly，behavioral scientist and senior lecturer，said："We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy．In fact，the research suggests people may eat less and burn more energy when in a warmer indoor environment．
The 13-year study，published in the journal Obesity，involved more than 100，000adults across England．
Researchers found reduced weight levels among people living in homes heated to above 23°C（73F），which involved about 15，000of the households studied．
Dr Daly said："As national gas bills continue to rise faster than the rate of inflation，this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs．"
This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods，exercise classes and sporting activities，and therefore finding it easier to maintain a low BMI level．The study took age，sex，social class and other factors into account．
"The comfortable temperature of 20°C-23°C is where we feel comfortable in our clothes and are neither hot nor cold．At temperatures above this，we use more energy and we eat less because our appetite is affected．"

29．The findings of the research can be described asB．
A．horrible  B．surprising  C．funny  D．encouraging
30．According to the passage，with rising gas bills，people may turn down or off their heating toC．
A．stay in shape    B．maintain a low BMI level
C．save money       D．a(chǎn)void eating more
31．Which of the following can be the best title for the passage？A
A．Obesity links to poorly-heated homes
B．Well-heated home's contribute to obesity
C．Obesity---A weighty problem in England
D．Rising energy bills help maintain a healthy weight．

12．HAVE you ever gotten a song kept in your head？You sing it all the time-on your way to school，before sleep，even when you're sitting on the toilet．You want to forget it，but the music just keeps sounding in your head．
Some people call these annoying songs"earworms"because they are just like parasites（寄生蟲(chóng)）-they"live"in your ears and refuse to leave even when you tell them to．
But why do some songs become earworms and not others？According to Ira Hyman，a music psychologist at Western Washington University，people are more likely to remember songs that are simple and repetitive，especially ones with that type of music．"Choruses tend to get stuck in your head because they are the bit we know best，"Hyman told The Tele-graph．
If you've got an earworm，you can suffer an attack without even hearing it．Seeing words from the song or hearing someone mention it could both cause the domino effect that starts the song running．
Scientists have been trying to find a solution to deal with earworms．They say the best way is to fill your mind with something else．But here is the tricky part：the task you do should be neither too hard nor too easy．The harder you try not to think about the music，the more you won't be able to help it．On the contrary，a task like jogging which is too easy won't keep your brain busy enough，and that could allow the song to come back．
"The key is to find something that will give the right level of challenge．"said Hymen．Reading a difficult book or a good novel could count．

21．What can we 1earn from the passage？A
A．People may sing earworms everywhere．
B．You can suffer an attack of an earworm on hearing it．
C．You can forget the melody by trying hard not to think about it．
D．Hearing someone sing the song can't start the song running in your head．
22．What kinds of songs will probably become earworms？C
A．Classical songs．
B．Songs we 1ike best．
C．Simple and repetitive songs．
D．Songs that are unfinished．
23．According to the article，if you want to get rid of earworms，you shouldC．
A．Listen to a new song
B．Try not to think of the song
C．Read an interesting novel
D．Do some exercise like jogging．

2．A．Cosmetics were used in different countries a long time ago．
B．The most widely used cosmetic is probably lipstick
C．Cosmetics were made most use of in Indian．
D．At one time，some cosmetics were not safe．
E．Some people even have cosmetic surgery．
F．The Romans also used cosmetics．

Millions of women use cosmetics，often called‘make-up'．The cosmetics industry is one of the biggest in the world．Most large stores sell cosmetics，and there are always shops at airports selling them cheaply．
The word‘cosmetics'refers to anything that people put on their faces to make them look better．Lipstick，face powder and cream，and eye make-up are the most popular．Although more women than men use cosmetics，there are cosmetics for men as well as women．
（61）E In order to make their faces look different．They have the shape of their noses and eyes changed．
（62）B Many women who do not wear any other make-up will often put on a little lipstick．Lipstick is made by mixing together different oils and colors．This mixture is then allowed to get hard and is cut into the shape of a small pencil．When a woman presses the lipstick to her lips，the end of it becomes soft，and some of it sticks to her lips，giving them extra color．
（63）A Cosmetics were probably first used in India，but it was the Egyptians，six thousand years ago，who made the most use of them．Rich Egyptian women painted their eyes green and black．They used a red color to paint pretty designs on their fingernails，the palms of their hands and the soles of their feet．Pictures of Cleopatra always show her wearing a lot of make-up．
（64）F They liked to make their skin very white and to paint their eyes．They also used a kind of lipstick．
In England at one time，very rich women had baths in milk to make their skin beautiful．They also used a lot of sweet-smelling powder to stop people smelling their bodies，which were often very dirty because they did not wash very often or change their clothes．
（65）D They were bad for the skin，and some of the lipsticks and powders that people used were even poisonous．Nowadays，people in the cosmetics industry take great care to make sure that everything they use is completely safe．

9．High school in the United States starts too early．Given teenagers'sleep patterns，the ideal school start time could be as late as 11：30 a．m．-when many high school students have already finished half a school day and are eating lunch．
Researchers from Harvard and Oxford wrote about this new finding in a recent article in the journal Learning，Media，and Technology．In the article，Paul Kelley argued that，given when kids and teenagers are biologically conditioned to wake up，10-year-olds should start school at 8 a．m．，16-year-olds should start between 10 a．m．a(chǎn)nd 10：30 a．m．，and 18-year-olds should start between 11 a．m．a(chǎn)nd 11：30 a．m．
There's been lots of research done on sleep and performance in school-but this article argues that school should start even later than most proposals for a later start time call for．Teens aren't lazy-adults need to adjust．This isn't laziness-sleep patterns are a biological necessity．Reviewi ng evidence from studies around the world，the researchers argue that starting school later would help students learn more，perform better on tests，and even make teenagers less annoyed．When the Minneapolis Public Schools moved their start time from 7：15 a．m．to 8：40 a．m．，students liked the change and reported that"attendance，achievement，behavior，and mood improved．"
Parents were positive，too.92 percent said they liked the change，and parents reported that their kids were easier to live with when they weren't getting up so early．At the US Air Force Academy，where students were randomly assigned（分配；指派）to classes with earlier and later start times，students who started earlier performed worse all day long on those days．
The researchers argue that this is partly cultural，and that getting up early is still seen as a virtue．That's wrong，They write："A common belief is that adolescents are tired because they choose to stay up too late，or are difficult to wake in the morning because they are lazy．Educators tend to think that adolescents learn best in the morning and if they simply went to sleep earlier，it would improve their concentration．The truth is that adults need to be educated．"
61．What does the passage mainly argue about？A
A．The time to start high school．
B．The performance of teenagers．
C．The sleep patterns of the teenagers．
D．The common belief of adolescents．
62．From Paul Kelley's research，pe ople can concludeB．
A．the earlier the children get up，the cleverer they will become
B．the elder the children are，the later they should start learning
C．the more time children spend learning，the better they will be
D．the later children wake up，the more knowledge they can get
63．Which is NOT the benefit of starting school later in Paragraph3？D
A．Gaining more knowledge．
B．Getting higher marks．
C．Making mood better．
D．Attending school later．
64．How did the parents think of starting late？C
A．The students are losing a virtue．
B．The adults need to be taught．
C．The students benefit from that．
D．The adults become lazier．
65．What should the students do to perform well in school，according to the educators？D

6．Life on land probably began about 430million years ago，thought it had existed in the water for perhaps as long as 3，000million years．When we think of the first life on land，we probably think of strange animals coming out of the oceans，but，in fact，no animals could have been living if plants had not been on land first．Plants had to be on land before animals arrived．They supplied the first land animals with food necessary to live，since they-the plants are the only form of life that is able to get and store energy．
