8．（1）A one-person solar car that can be transformed into an electric moped （ 助力車 ），a door light powered by opening and closing a door and a cloak （披風） of invisibility are three innovative inventions recently created by college students．
     Here comes the sun
（2）The 100-kilogram blue solar car invented by 10 students at Southwest University's College of Engineering and Technology in Chongqing has a top with four solar panels that charge the battery that powers the auto．"The car is easy to drive．A person without any driving experiences could learn to use it in several minutes．It fits for campus and the golf course，"He Daijie，the leader of the invention team and a senior at the college，told the Global Times．"Or if one prefers it can be turned into an electric moped，"he said．
     Seeing the light
     （3）Four students at Shenyang University of Technology in Liaoning Province invented a door light  powered by electric energy produced by opening and closing a door．
    （4）When people open or close a door，tlie door produces mechanical energy that could be turned into  electric energy．After numerous tests for several months，the students fixed a joint lever （liE^ff） above  the door that connects the door and a speeding gear case to drive a generator attached to the door and  send energy to storage cells．The storage cells provide ______ for the light．
    Invisibility cloak
（5）Many people daydream of an invisibility cloak like Harry Potter's and three graduate students in  optics （光學） from Nanjing University of Aeronautics and Astronautics （航空航天） have actually  nvented  one．Special Ferro-electric （鐵電體） materials on the cloak reduce the scattering of light of an object  wrapped with the cloak，and thus making the object"invisible，"according to Li Peining，one of the three  students．Li said he is confident about the future of the cloaks．"With the appearance and application of new meta-materials，the cloak could be used in military battles and communications，"he said．
76．What is the main idea of the passage？It introduces three innovative inventions created by college students． 
77．Fill in the blank in Paragraph 4 with proper words．（no more than 3 words）electric energy/electricity
78．Which invention do you think is environmentally friendly？Why？（no more than 15 words）."Seeing the light"/"The door light"．Because it can save much electricity．Or"Here comes the sun"/"The solar car"．Because it can make use of solar power and save gas． 
79．What does the underlined word"it"in para 2 mean？（no more than 5 words）The solar car．/The one-person solar car． 
80．In which fields are invisibility cloaks used？（no more than 10 words）In military battles and communications．．

分析 本文主要介紹了大學生的三種新的發(fā)明．

解答 76．It introduces three innovative inventions created by college students
77．electric energy/electricity
78．"Seeing the light"/"The door light"．Because it can save much electricity．
Or"Here comes the sun"/"The solar car"．Because it can make use of solar power and save gas．
79．The solar car/The one-person solar car．
80．In military battles and communications．
76  It introduces three innovative inventions created by college students．主旨大意題．  開頭指出"three innovative inventions recently created by college students"，下文分別是對這三種發(fā)明的詳細介紹，故主旨為：It introduces three innovative inventions created by college students．
77  electric energy/electricity   細節(jié)題．  本段指出人們開關門的動能可以轉化為電能儲存、備用，"…the door produces mechanical energy that could be turned into electric energ"說明了這一點．由此可知 electric energy/electricity  符合題意，存儲電池能夠為燈提供電力． 
78  Seeing the light"/"The door light"．Because it can save much electricity．Or"Here comes the sun"/"The solar car"．Because it can make use of solar power and save gas．細節(jié)題．"Seeing the light"這種發(fā)明將開關門的動能轉化為電能備用，能夠節(jié)約電力，是環(huán)境友好型產品． 故此處答案為："Seeing the light"/"The door light"．Because it can save much electricity．
79  The solar car．/The one-person solar car．猜測詞義題．  文中第二段均在介紹 the 100-kilogram blue solar car，段末"Or if one prefers it can be turned into an electric moped"指出這種車可以當作電動助力車，承接前文"The car is easy to drive…"，it 指的仍為 The solar car．
80  In military battles and communications．細節(jié)題．根據(jù)文章最后一段．"With the appearance and application of new meta-materials，the cloak could be used in military battles and communications，"he said．可知隱形斗篷可用于軍事斗爭和通訊．

點評 做閱讀表達題時，理清文章的脈絡、掌握文章的主旨大意，并能運用簡潔的語言表達．回答要有針對性觀點要明確．不要摘抄文章原句．

18．Scientists have made sure that most of the overweight people who try to lose weight by cutting calories or exercising will return to their former size．Fewer than 10percent of the 12million British people who go on a diet each year succeed in losing significant amounts of weight and most of those who do put on all weight again within a year． The study of 25，000people provides further evidence of the popularity of‘yo-yo dieting'where people on a diet get into a cycle of losing weight and regaining it．The scientists，from the Medical Research Council's National Survey of Health and Development，have concluded it is better to avoid getting fat at the beginning．They followed 5，362men and women from their birth in 1946and 20，000from birth in 1958，measuring their weight and blood pressure and judging their lifestyles．The researchers found both groups began gaining weight in the 1980s and have steadily increased in size ever since．
Dr Rebecca Hardy，the council's programme leader on body size，said："Once people become overweight，they continue upwards．They hardly ever go back down．They may lose some weight but very few get back to normal．The best policy is to prevent people becoming overweight．For men weight goes up steadily through life．For women it starts slowly and accelerates in the mid-thirties．"
But the findings of the study do not mean dieting is pointless，as eating less and taking more exercise can increase fitness and lower blood pressure．In 2009，a quarter of adults and 14percent of children were obese（過度肥胖的），according to the Department of Health's latest Health Survey for England．It has been predicted that 60percent of us will be obese by 2050，leading to even more cases of diabetes，heart disease and cancer．Experts said we are programmed to put on weight rather than lose it．Dieting can make this tendency worse as decreasing calorie intake causes the body to go into starvation mode and reduce the amount of energy it naturally expends，making it even harder to lose weight．
60．According to Dr Rebecca Hardy，which of the following is TRUE？B
A．It is easier for men to lose weight than women．′
B．Never to become fat is the best way of keeping a good shape．
C．Once people lose weight，they never put on weight again．
D．The fact that fat people keep their weight upwards is unusual．
61．The author says"the study's findings do not mean dieting is pointless"becauseD．
A．the study lacks believable facts
B．obese people are confident in losing weight
C．dieting can never make a few people lose weight
D．dieting and sports help to keep people free from some diseases
62．From the last paragraph，we can learn thatC．
A．being overweight is a lasting problem through the human history
B．the idea that people lose weight with mechanisms is practical
C．decreasing calorie intake makes it even harder to lose weight
D．by 2050more and more people will have got unfit because of losing weight
63．Which of the following can serve as the best title of the passage？A
A．Fat people can't really keep the weight off．
B．Which is better：cutting calories or exercising？
C．A new study on people's health．

3．How to Succeed in Science
To succeed in science，you need a lot more than luck．In my view，you have to combine intelligence with a willingness not to follow conventions when they block your path forward．Thus，these have come to be my rules for success．
1（36）E
That might sound proud，but the fact is that you must always turn to people who are brighter than yourself．It's like playing any game．Even as a child，I never wanted to play games with anyone who was as bad as I was．If you win，it gives you no pleasure．And in the game of science  or life，the highest goal isn't simply to win； it's to win at something really difficult．（37）C
2．Take risks
To make a huge success，a scientist has to be prepared to get into deep trouble．If you are going to make a huge jump in science，you will very likely be unqualified to succeed by definition．（38）G  This can be more than personally upsetting．
3．Never do anything that bores you．
My experience in science is that someone is always telling you to do things，and then leave you alone．I'm not good enough to do well in something I dislike．（39）F
It's very hard to succeed if you don't want to be with other scientists-you have to go to key meetings where you spot key facts that would have escaped you．And you have to chat with your competitors，even if you find them objectionable．
So my final rule is：（40）B

A．Meet challenges with great courage．
B．If you can't stand to be with your real peers，get out of science．
C．Put another way，it's to go somewhere beyond your ability and come out on top．
D．Be sure you always have someone to save you from a deep mess．
E．Avoid foolish people．
F．In fact，I find it hard to do well in something I like．
G．Besides，you even have to be prepared to disbelieve your scientific heroes．

20．Over 500dogs being delivered to a butcher house were saved by a Chinese animal protection organization．The incident then triggered debate among Chinese netizens about the necessity of pouring so much money and efforts into saving dogs．
On Friday，a truck loaded with over 500dogs were stopped by volunteers from animal protection organization on Jingha Expressway Beijing section．
Beijing Times reported these dogs were being delivered to slaughter houses in the city of Changchun，northeast Jilin Province and would be eventually served on dinner tables．
After negotiations with the truck driver，pet service provider Leepet Holding Corp．and a philanthropic foundation，Shang shan Foundation purchased these dogs，each paying 50，000yuan．Dogs were then delivered to the headquarter of China Small Animal Protection Association （CSAPA），being taken care of and waiting for adoption．
After the"dog saving mission"was reported，Chinese net users debate over whether saving dogs worth so much efforts and money while there are still many poor and needy people in China lacking assistance．
Some net users argue the"dog saving mission"is placing overt attention to animals while lots of needy people are still left unattended．
A microblogger"Xiaowulaitajie"said on China's twitter like website，weibo．com，"Dogs are saved，adopted and they attracted media spotlight．We'd better spend such money and take such efforts in helping the needy people．"
Another microblogger，Liluping，said"We poured such huge sum of money into saving dogs．I would rather the money be spent on disaster relief．"
Some applaud volunteers'actions and show eagerness of offering their helping hands to those saved dogs．
Still many disapprove those"saving dogs"critics，but they argue that such act nonetheless promotes social progress．
A microblogger named"broken bridge"said，saving dogs does not run counter to taking care of people．Such enthusiasm in public affairs will help raise social awareness in helping the needy．
I think people and animals are created equal．Attention should be paid to people as well as animals．

68．Where did the article come from？C
A．A storybook．  B．A novel．  C．Internet．  D．A magazine．
69．Which one has the similar meaning to the underlined phrase"run counter to"in the last but one paragraph？B
A．meet with       B．go against     C．agree with     D．come across
70．Whose opinion is closest to the writer's？B
A．Some net users'．
B．Broken bridge's．
C．Liluping's．
D．Xiaowulaitajie's．
71．The following statements are TRUE exceptC．
A．All the people don't think it right to save these dogs with so much money．
B．More than 25，000，000yuan was given to the truck driver to purchase these dogs．
C．These dogs were finally saved and sent back to their owners．
D．Some people think it better to spend the money in helping the needy people．
