13．Eat healthier．Exercise twice a week．Read more books．Lose weight．We make the same resolutions（决心） every year，but most of us fail，dying out after only a few days or，at best，weeks．Even the most successful among us crash and burn when it comes to personal change．President-elect Barack Obama struggles to remove his cigarette habit．
Professionals who help people make changes in their lives suggest the change is determined not by one's surroundings，but one's mind．Beginning with small goals or steps usually leads to a bigger payoff later，they say．But they caution that the experience is different for everyone．
"People are more likely to make positive changes in their lives not only when their friends do，but when their friends of friends do，and when their friends of friends of friends do，"said Nicholas Christakis，a professor of medical sociology at Harvard University．"People are better able to make changes in their lives-lose weight，quit smoking，become happy-when they do this with a large number of other people，and so taking advantage of your social network ties can result in a magnification of your own efforts．"
Jhonny Augustin understands that well．His resolution for 2008 was to shed 30 pounds from his 237-pound frame．But the change didn't come easily．He said，"I'm a huge procrastinator，I kept putting it off until tomorrow．I didn't get to do it until the summer．"However，Augustin got inspired when he saw his older brother working out．Today，Augustin weighs 190 pounds．
"Of course，change can happen only if people don't set their expectations too high or try to tackle too many changes at once； one of the biggest mistakes we make is setting unrealistic goals，"said Dalia Llera，a psychologist and associate professor of counseling and psychology at Lesley University．"You can't accomplish in a few weeks what you haven't accomplished in a few years，"said Llera．
46．From the first paragraph we can infer that．A
A．change for a person is challenging
B．famous people have great determination
C．most people don't want to change themselves
D．personal change is beyond belief
47．It is known from Nicholas christkis that．B
A．making a change is easier with support from a cheerful group of friends
B．social networks have great effect on one's change
C．people who have the same attitude often get together
D．people's mood can contribute to their efforts
48．The word"procrastinator"in Paragraph 4 refers to those who．C
A．have great determination to make a change
B．have no desire to do something great
C．put off work especially because of laziness
D．have habitual carelessness and laziness
49．According to the passage，Dalia Liera suggested that．D
A．people should understand their goals well
B．people should try their best to change themselves
C．people should have confidence and positive habits
D．people should start with setting small goals to meet
50．The passage is mainly about．D
A．the reason why losing weight is so hard
B．the effect of the positive change
C．the attitudes towards change in life
D．the ways of making a change．

分析本文为科教类论说文，文章首先分析日常生活中我们常常下决心，但是这个决心很难坚持下去，由此引出"改变难"；然后通过具体的事例和专家的分析说明应该怎样去做才能改变：利用社交网络，和很多人一起做，这能使自己的改变努力产生巨大的结果；起初设定小目标和小步伐才能最终通往最终的大目标．

解答 46．答案是A．推断题；由第一段中"Even the most successful among us crash and burn when it comes to personal change．（当涉及到个人的改变时，即使我们中最成功的人也会失败）"可以推断，改变很难，故选A．
47．答案是B．细节理解题；根据第三段中 Nicholas christkis 说的话"People are better able to make changes in their lives-lose weight，quit smoking，become happy-when they do this with a large number of other people，and so taking advantage of your social network ties can result in a magnification of your own efforts．"可知，当和很多人一起做时人们更容易改变；所有他建议"利用社交网络能使自己的努力产生巨大的结果"，故选B．
48．答案是C．词汇猜测题；由下一句"I kept putting it off until tomorrow．（我喜欢把事件推迟动明天）"推测 Jhonny Augustin 认为自己是严重的拖延症者，喜欢put off（推迟），故选C．
49．答案是D．细节理解题；根据最后一段中Dalia Llera说讲的话，特别是"change can happen only if people don't set their expectations too high or try to tackle too many changes at once（只有当人们设定的期望值不是太高，或不要一下子处理太多的改变的情况下，改变才会发生；）"可以判断，Dalia Liera 建议设定小目标；故选D．
50．答案是D．主旨大意题；文章首先分析日常生活中我们常常下决心，但是这个决心很难坚持下去，由此引出"改变难"；然后通过具体的事例和专家的分析说明应该怎样去做才能改变，故本文主要分析如何改变，答案选D．

点评阅读要在整体理解文章的基础上，在做细节题时根据题干定位细节，在语境中正确理解原句，然后对照选项做出合理的判断；必要的时候要进行推理，透过句子表面看作者的真正意图．如果是主旨大意的判断要把握文章整体，避免以偏概全．

4．

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．
80．D
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．

8．

We've used the wind as an energy source for a long time．The Babylonians and Chinese were using wind power to pump water for irrigating crops 4，000 years ago，and sailing boats were around long before that．Wind power was used in the Middle Ages，in Europe，to grind（磨碎） corn，which is where the term"windmill"comes from．
We can use the energy in the wind by building a tall tower，with a large propellor on the top．The wind blows the propellor round，which turns a generator to produce electricity．We tend to build many of these towers together，to make a"wind farm"and produce more electricity．The more towers，the more wind，and the larger the propellors，the more electricity we can make．It's only worth building wind farms in places that have strong，steady winds，although boats and caravans（大篷车）increasingly have small wind generators to help keep their batteries charged．
The best places for wind farms are in coastal areas，at the tops of rounded hills，open plains and gaps in mountains-places where the wind is strong and reliable．Some are offshore．To be worthwhile，you need an average wind speed of around 25 km/h．Most wind farms in the UK are in Cornwall or Wales．Isolated places such as farms may have their own wind generators．In California，several"wind farms"supply electricity to homes around Los Angeles．
The propellors are large，to obtain energy from the largest possible volume of air．The blades can be angled to cope with varying wind speeds．Some designs use vertical turbines（垂直涡轮机），which don't need to be turned to face the wind．The towers are tall，to get the propellors as high as possible，up to where the wind is stronger．This means that the land beneath can still be used for farming．
66．The first paragraph aims to introduce to usD．
A．the function of wind power
B．the source of wind power
C．the nations using wind power
D．the history of using wind power
67．How does a wind power work？D
A．The generator turns the propeller blades and produce electricity．
B．The tall tower helps turn the energy in the air into electricity．
C．Warm air rises and makes the propellor move round．
D．The propellor blown round by wind turns the generator to produce electricity．
68．The best places for building the wind farm are places whereD．
A．boats and caravans can often be seen
B．isolated farms don't have enough electricity
C．there are less human activities
D．the wind is strong and reliable
69．We can infer from the passage thatB．
A．wind farms will not take up too much farming land
B．wind farms need no fuel because wind is free
C．the blades can be angled to turn to face the wind wherever it comes from
D．the higher and larger the towers are，the stronger the wind is
70．What can be a suitable title for the passage？B
A．Where to build a wind farm．
B．ABC of the using of wind energy．
C．How to make best use of wind．
D．Wind energy is the best energy．

18．It is one of the greatest mysteries of nature．In case you haven't noticed，all living things follow very definite，individual rhythms，all as regular as a clock，but what makes them regular？
    Though many scientists maintain that these rhythms are the result of some outside force like gravity or radiation or both，the results of most scientific researches agree with other scientists who believe that each living thing has its own built-in biological"time clock．"
    Take the mystery of migration for example．Scientists can't really explain why many species of birds migrate in the autumn even though the temperature is still summery．The birds just seem to snub the comfortable weather that they are having．When a certain time comes，they travel south by the thousand．In spring time，they migrate northwards even though there probably is snow still covering the ground when they finally arrive．Something said"go，"and they did．
    Animals that hibernate （冬眠） are obeying individual time clocks，too．When their clock indicates the time to take a winter's nap，they do，and nothing can stop them．At a certain time in the spring，they wake up and come out regardless of the weather outside．
    Plants appear to have yearly rhythms，such as the sprouting of seeds，and they also have daily rhythms．Notice sometimes that plants raise their leaves in daylight and lower them at night．
    If you live along the California coast，you can easily observe a demonstration of this mysterious clock functioning regularly．There，from February to September，the highest tides occur exactly every fourteen and four-fifths days，and during these high tides，but at no other time，small silvery fish called grunions surf-ride a wave to the beach．There the female deposits her eggs in the sand and the male fertilizes them； then both hitch a wave-ride back to the sea．Exactly fourteen and four-fifths days later，never before or after，the tiny eggs hatch，and the high tide carries the new babies out to sea．

72．According to the passage，the mysterious rhythms result fromD．
   A．the influence of gravity on living species
   B．the effect of radiation on living species
   C．the influence of a mysterious outer force on living species
   D．the internal mechanism inside the living species
73．The underlined word"snub"in the third paragraph probably meansB．
   A．fight          B．ignore          C．symbolize         D．criticize
74．Which of the following statements is NOT TRUE？D
   A．Hibernating animals are obeying an internal time clock．
   B．The positioning of the leaves of some plants is due to the daily rhythms．
   C．The internal clock functioning is demonstrated in the reproducing habits of grunions．
   D．The yearly hibernation is more because of the weather influence than the biological functioning．
75．The passage is mainly aboutA．
   A．the rhythms of life
   B．the reasons of mysterious hibernation
   C．strange behaviors of species
   D．the timing for different events in the world of species．

5．Some people may be born happy，while others are genetically negative，scientists have suggested in a study published late February in a British journal．
Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter （神经传递素） serotonin works within the brain．Serotonin，a hormone （荷尔蒙），passes chemical messages between nerve cells．It has been closely linked to mood．Several anti-depressant （抗抑郁） drugs regulate serotonin levels．
Scientists had also identified three variants （变体） of the gene．Two so-called"short"variants were linked to a higher risk of depression and suicide （自杀） attempts．Unlike the two"short"variants，the"long"variant of 5-HTTLPR showed a clear dislike of negative images，such as fierce animals，and a clear liking for positive ones，such as flowers．
Researchers from the University of Essex in Britain showed participants a series of images，which were divided into three kinds：negative ones aimed at inspiring fear or stress such as a snake or person about to commit suicide，pleasant ones and neutral （中性的） ones．
The participants who had the long variant of the 5-HTTLPR gene"showed a clear dislike of negative material alongside a careful attention for positive material，"the researchers found．They paid close attention to the pretty pictures，and ignored the frightening ones．On the other hand，the short variant groups had the opposite reaction．
In January，the Australian government organized"happiness workshops"，teaching government staff how to be happy．The department that held the"happiness workshops"said unhappy staff weren't productive staff．
Australian political opposition parties have argued that the"happiness workshops"are probably a waste of money and couldn't increase productivity as intended．However，whether the workshop will have a happy or disappointing result，we will have to wait and see．

71．Various kinds of images were shown to the participants toC．
A．draw their attention
B．cater to their different tastes
C．find out about their reactions
D．teach them to improve their artistic appreciation
72．The"short"variants of 5-HTTLPR differ from the"long"variants of 5-HTTLPR in thatB．
A．the former is connected with positive mood while the latter negative
B．the former is connected with negative mood while the latter positive
C．the former has a greater effect on one's mood than the latter
D．the latter has a greater effect on one's mood than the former
73．Which of the following statements is true about"happiness workshops"？D
A．Most people believe that they are a waste of money．
B．They will be beneficial in the long run．
C．The purpose of"happiness workshops"is to teach all Australians to be happy．
D．They are organized in the belief that happy staff can work more efficiently．
74．It can be learned from the article thatA．
A．drugs can be used to control people's serotonin levels
B．happiness is more important than sadness
C．nothing can affect our mood
D．people with the short variant of 5-HTTLPR prefer a flower to a snake
75．The article is mainly aboutB．
A．the reason for the foundation of"happiness workshops"
B．the link between people's mood and their gene
C．the study on people's likes and dislikes
D．the differences in people's attitude towards life．

2．I'm usually fairly doubtful about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50years ago．While any of these statements might be true，they are practically impossible to prove scientifically．Still，I was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s．In fact，the analysis showed，normal children aged 9to 17exhibit a higher level of anxiety today than children who were treated for mental illness 50years ago．
Why are America's kids so stressed？According to the report there are two main causes：increasing loneliness─brought on by high divorce rates and little communication with society，among other things─and a growing perception that the world is a more dangerous place．
Given that we can't turn the clock back，adults can still do plenty to help the next generation handle such difficulties．At the top of the list is giving children a better appreciation of the limits of individualism （个人主义）．No child is an island．Strengthening social ties helps protect individuals against stress．To help kids build stronger connections with others，you can pull the plug on TVs and computers．Your family will thank you later．They will have more time for face-to-face relationships，and they will get more sleep．
Limit the amount of virtual  violence your children are exposed to．It's not just video games and movies； children see a lot of murder and crime on the local news．Keep your expectations for your children reasonable．Many highly successful people never attended Harvard or Yale．Make exercise part of your daily routine．It will help you deal with your own anxieties and provide a good model for your kids．Sometimes anxiety is unavoidable．But it doesn't have to ruin your life．

125．The author thinks that the conclusions of any research comparing people's state of mind today with people's state of mind in the past areD．
A．surprising           B．confusing
C．interesting          D．questionable
126．What does the author mean when he says，"we can't turn the clock back"（Paragraph 3）？B
A．It's impossible to slow down the pace of change．
B．The social reality children are facing cannot be changed．
C．Lessons learned from the past should not be forgotten．
D．It's impossible to forget the past．
127．According to the analysis，compared with normal children today，children treated as mentally ill 50years agoC．
A．had little communication with friends
B．were probably less self-centered
C．probably suffered less from anxiety
D．were considered less individualistic
128．The first and most important thing parents should do to help their children isC．
A．to provide the children with a safer environment
B．to lower their expectations for the children
C．to get the children more active socially
D．to set an example for the children to follow
129．What conclusion can be drawn from the passage？A
A．Anxiety，though unavoidable，can be dealt with．
B．Children's anxiety has been taken too seriously．
C．Children's anxiety can disappear with more parental care．
D．Anxiety，if properly controlled，may help children become mature．
