15．我們可以循環(huán)使用課本，以達到節(jié)約和減少污染的目的．（recycle； so as to）We can recycle our textbooks so as to save and reduce/cut down pollution．

分析 我們可以循環(huán)使用課本，以達到節(jié)約和減少污染的目的．

解答 答案：We can recycle our textbooks so as to save and reduce/cut down pollution．
解析：根據(jù)所給英文提示可知，"達到節(jié)約和減少污染的目的"可以表達為：so as to save and reduce/cut down pollution（為了節(jié)約和減少污染）；需要注意的是so as to這個結構中，to之后要用動詞原形．

點評 本題考查句子翻譯，做此類題目時一定要根據(jù)中文及英文題干確定需要翻譯的成分，再找出與之對應的英文并考慮各成分是否有形式的改變．

5．Spending as little as  5a day on someone else could significantly（較大地） boost happiness，the team at the University of British Columbia found．
Their experiments on more than 630Americans showed they were measurably （可測量出） happier when they spent money on others-even if they thought spending the money on themselves would make them happier．
"We wanted to test our theory that how people spend their money is at least as important as how much money they earn，"said Elizabeth Dunn，a psychologist（心理學家） at the University of British Columbia．They asked their 600volunteers first to rate （評估） their general happiness，report their annual income （年收入） and detail their monthly spending including bills，gifts for themselves，gifts for others and donations to charity．
"No matter how much income each person made，those who spent money on others reported greater happiness，while those who spent more on themselves did not，"Dunn said in a statement．
Dunn's team also surveyed 16employees at a company in Boston before and after they received an annual profit sharing bonus（紅利）of between  3，000and  8，000．"Employees who devoted more of their bonus to prosocial （支持社會） spending experienced greater happiness after receiving the bonus，and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself，"they wrote in their report，published in the journal Science．
They gave their volunteers  5or  20and half and clear instructions on how to spend it．Those who spent the money on someone or something else reported feeling happier about it．
"These findings suggest that very minor changes in spending allocations （津貼）-as little as $ 5-may be enough to produce real gains in happiness on a given day，"Dunn said．
32．What is the general idea of the passage？D
A．The more you earn，the greater happiness you will get．
B．Spending more money on yourself will make you happier．
C．You can spend only  5a day on someone else to get happiness．
D．If you spend money on someone else，you will feel happier．
33．The underlined word"boost"in the first paragraph probably meansB．
A．help to find    B．help to increase  C．help to bring  D．help to get
34．Which of the following statements is NOT true according to the passage？C
A．Very small changes in spending your money may be enough to gain happiness．
B．People usually think spending money on themselves will make them happier．
C．Those who spend more money on others can get much more bonus．
D．Researchers think that how people spend their money is at least as important as how much money they earn．
35．Dunn isA．
A．a(chǎn) psychologist at a university      
B． an employee in a company
C．a(chǎn) reporter in a journal            
D．a(chǎn) volunteer in the experiment．

20．He has millions of students from all around the world．They listen to his classes online but never see his face on the screen．Salman Khan，39，from the US，is the founder of the learning website Khan Academy．
Unlike other online courses that film teachers giving classes，Khan's videos only use his voice and a digital blackboard for writing．He says he doesn't want a human face to distract students．Khan also makes his classes as short as 10to 15minutes so students don't lose interest．They can also earn （獲得） points from taking these classes．
The courses are translated into more than 36different languages including Chinese．About 80teachers from the world's top universities are now also teaching on the website．But all this started nine years ago with just one man-Salman Khan．υThese kinds of special courses make Khan Academy one of the world's most popular online education websites．
In 2006，Khan made homemade videos to help his seventh grade cousin with math．He posted the videos online and got thousands of views．This encouraged Khan to make more videos and create his own website Khan Academy．
As a Bangladeshi-American （孟加拉裔美國人），Khan understands that many kids，especially those in developing countries，cannot get a good education．He himself has three degrees （學位） from Massachusetts Institute of Technology and one from Harvard．He wants to use his knowledge to help more people．Thus，his courses are all offered for free．"Our mission （任務） is to provide a free，world-class education for anyone，anywhere，"he said．
Khan's website has not only become very popular worldwide but has also won a lot of respect．Even Bill Gates，the founder of Microsoft，is one of his fans．Gates donated over $1.5million （9.6million yuan） to support Khan and named him the"teacher to the world"．

28．From Paragraphs 1-2，we learn thatB．

4．t seems that nowadays all the world are concerned about genetically modified foods （GM foods）．GM foods develop from genetically modified organisms，which have had specific changes introduced into their DNA by genetic engineering techniques．These techniques are much more precise where an organism is exposed to chemicals to create a non-specific but stable change．For many people，the high-tech production raises all kinds of environmental，health and safety problems．Particularly in countries with long farming traditions，the idea seems against nature．
In fact，GM foods are already very much a part of our lives．They were first put on the market in 1996．A third of the corn and more than half the cotton grown in the US last year was the product of biotechnology，according to the Department of Agriculture．More than 65 million acres of genetically modified crops will be planted in the US this year．The genetic genie is out of the bottle．
However，like any new product entering the food chain，GM foods must be subjec ted to careful testing．In wealthy countries，the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from，and a supply that goes beyond the needs．In developing countries desperate to feed fast-growing and underfed populations，the matter is simpler and much more urgent：do the benefits of biotech outweigh the risks？
The statistics on population growth and hunger are disturbing．Last year the world's population reached 6 billion．The UN states that nearly 800 million people around the world are unhealthy．About 400 million women of childbearing age don't have enough iron，which means their babies are exposed to various birth defects．As many as 100 million children suffer from vitamin A deficiency，a leading cause of blindness．
How can biotech help？Genetic engineering is widely used to produce plants and animals with better nutritional values．Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops．Biotech can also improve farming productivity in places where food shortage is caused by crop damage attributable to drought，poor soil and crop viruses．
32．The passage mainly talks aboutC．
A．the world's food problem                    B．the development in biotech
C．the genetically modified foods               D．the way to solve food shortage
33．According to the passage，GM foodsB．
A．a(chǎn)re not cared about in wealthy countries at all．
B．may help solve the problem of poor nutrition
C．a(chǎn)re better than naturally grown foods in some ways．
D．can cause serious trouble in developing countries
34．The underlined sentence"The genetic genie is out of the bottle．"in paragraph 2 probably means thatC．
A．GM foods are available everywhere
B．the technology in producing GM foods is advanced
C．genetic technology has been into markets．
D．genetic technology may have uncontrollable powers
35．In countries with long farming traditions，people's attitude towards GM foods seemsC．
A．Optimistic．B．Approving．C．Disapproving．D．Unbelievable．
