13．Recently there was a major discovery in the scientific research-the mapping of all DNA in a human gene（基因） is complete．Couple of years ago，this seems an impossible task for scientist to accomplish．All this progress in science leads us to believe that the day，when the human being will be cloned，is not far away．Human cloning has always been a topic of argument，in terms of morality or religion．
    Taking a look at why cloning might be beneficial，among many cases，it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning．If the clone was free of genetic limitations．then the other clone would be as well．The latter could foe inserted in the woman and allowed to ripen to term．Moreover，cloning would enable women，who can't get pregnant，to have children of their own．
    Cloning humans would also mean that organs could be cloned，so it would be a source of perfect transfer organs．This，surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single （or more） organ （s）．It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists．
    Arguments against cloning are also on a perfectly practical side．Primarily，I believe that cloning would step in the normal"cycle"of life．There would be a large number of same genes，which reduce the chances of improvement，and，in turn，development-the fundamental reason how living things naturally adapt to the ever-changing environment．Life processes failing to do so might result in untimely disappearance．Furthermore，cloning would make the uniqueness that each one of us possesses disappear．Thus，leading to creation of genetically engineered groups of people for specific purposes and，chances are，that those individuals would be regarded as"objects"rather than people in the society．
    Scientists haven't 100 per cent．guaranteed that the first cloned humans will be normal．Thus this could result in introduction of additional limitations in the human"gene-pool"．
    Regarding such arguable topics in"black or white"approach seems very innocent to me personally．We should rather try to look at all"shades"of it．I believe that cloning is only legal if its purpose is for cloning organs； not humans．Then we could regard this as for"saving life"instead of"creating life"．I believe cloning humans is morally and socially unacceptable．
67．Which of the following is true according to the passage？C
A．Genetic limitation will be beneficial for some women．
B．A large number of genes will prevent us from developing．         
C．Prohibition of cloning might limit the freedom of scientists．
D．First cloned humans might be normal according to scientists．
68．What's the author's opinion on cloning？D
A．Cloning should be entirely banned．
B．Cloning should be used in creating life．
C．Cloning will take away the right to reproduce．
D．Cloning is acceptable if it is used for cloning organs．
69．Where can you read this article？B
A．In a story book．        
B．In a magazine．
C．In a science fiction．   
D．In a brochure．
70．Which of the following shows the structure of the passage？A．

分析 本文是一篇科教类阅读，主要讲的是近来科研中的一项重要发现--人类基因中所有的DNA测绘都是完整的．

解答 67-70．CDBA
67题答案：C考查细节推理，根据原文第三段的It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists．有证据表明克隆的禁令是不符合法律的而且也会剥夺人们繁殖的权利并且会限制科学家的自由．可知本题答案为C选项．
68题答案：D考查细节推理，根据文章最后一段的I believe that cloning is only legal if its purpose is for cloning organs； not humans．我认为只有在目的是为克隆器官而不是人类时克隆才是合法的．可知本题答案为D选项．
69题答案：B考查细节推理，本文是一篇科学文章，故有可能出现在科学杂志中；因此本题答案为B选项．
70题答案：A考查主旨大意，文章的结构是：引出论点（第1段，人类的克隆是一个争论的话题，这涉及到道德与宗教）--围绕论点分别指出支持方（2、3段）与反对方（4、5段）--提出个人见解（第六段）．故本题答案为A选项．

点评 本文是一篇科教类阅读，题目涉及多道细节理解题，做题时结合原文和题目有针对 性找出相关语句进行仔细分析，结合选项选出正确答案．推理判断也是要在抓住关键句子的基础上合理的分析才能得出正确的答案．

3．As you are probably aware，the latest job market news isn't good．Unemployment is still more than 9percent，and new job growth has fallen close to zero．That's bad for the economy，of course．And it may be especially （61）discouraging（discourage） if you happen（62）to be looking （ look） for a job or hoping to change careers right now．But it actually shouldn't matter to you nearly as much as you think．
That's because job growth numbers don't matter to job（63）hunters （hunt） as much as job turnover （人员更替） data．After all，existing jobs open up every day due to promotions，resignations，firings and retirements．In both good times and bad，turnover creates more openings than economic growth （64）does．
I don't mean to suggest that overall job growth doesn't have an impact on one's ability to land a job．
But  （65）what often distinguishes those who land jobs from those who don't is their ability to stay motivated．They're willing to do the hard work of identifying their valuable skills； be （66）creative   （create） about where and how to look； learn how to present （67）themselves to potential employers； and keep （68）going （ go），even after repeated rejections．
So don't let the headlines fool you into giving up．Four million people get  （69）hired （ hire） every month in the U．S．You can be （70）one of them．
4．Do you know Australia？Australia is the largest island in the world．It is a little smaller than China．It is in the south of the earth．Australia is big，but its population is not large．The population of Australia is nearly as large as that of Shanghai．
The government has made enough laws to fight pollution．The cities in Australia have got little air or water pollution．The sky is blue and the water is clean．You can clearly see fish swimming in the rivers．Plants grow very well．
Last month we visited Perth，the biggest city in Western Australia，and went to a wild flowers'exhibition．There we saw a large number of wild flowers we had never seen before．We had a wonderful time．Perth is famous for its beautiful wild flowers．In spring every year Perth has the wild flowers'exhibition．After visiting Perth，we spent the day in the countryside．We sat down and had a rest near a path at the foot of a hill．It was quiet and we enjoyed ourselves．Suddenly we heard bells ringing at the top of the hill．What we saw made us pick up all our things and run back to the car as quickly as we could．There were about three hundred sheep coming towards us down the path．
Australia is famous for its sheep and kangaroos（袋鼠）．After a short drive from any town，you will find yourself in the middle of white sheep．Sheep，sheep，everywhere are sheep．

1．None of our early ancestors could digest milk as adults because their bodies never had to----milk drinking simply wasn't an option．As people began to extract milk from animals，though，some people developed the ability to keep drinking it throughout their lives．
Scientists now know of a milk-related mutation （ 变异） in our genes--the chemical instructions for life that we carry in almost every cell in our bodies．People who have a mutated form of one particular gene can drink milk just fine．People without the mutation tend to get sick from milk．
To figure out where，and possibly why，milk drinking started，some scientists have been looking at who has the milk-digesting mutation today．Patterns are striking．
Most adults in Northern and Central Europe are able to digest milk--and they do．Cheese and butter and other dairy products are popular in countries such as Sweden，Denmark，Germany and England．Because European settlers dominated North America，most people here can handle milk just fine，as well．That may explain why ice cream is such a popular dessert in the United States．
In much of Africa，Asia and South America，on the other hand，people tend to avoid dairy products because they lead to diarrhea （腹泻） and other stomach problems．（That's why you won't typically find cheese on the menu at a Chinese，Japanese or Ethiopian restaurant．） Native
Americans are also unable to digest milk．
Based on these genetic patterns，scientists have long thought that-milk drinking started inNorthern Europe，where dairy is an institution and the milk-digesting mutation is everywhere．
A recent study painted a different picture．With a computer medal，Thomas and colleagues looked at the spread of the milk-drinking mutation，farming and other related factor．Working backward，the scientists concluded that the first milk-thinkers lived in Central Europe around what's now Hungary about 7，500years ago．The practice didn't start farther north，as scientists had thought before．

66．Which of the following is the proper order of events according to the passage？C
a．Their children were able to digest milk as adults．
b．They got sick from the milk．
c．Some people got a mutation in their genes．
d．Some people tried drinking milk from animals．
e．Some people started to drink milk from animals on a regular basis．
A．c→d→b→e→a     B．d→e→b→c→a    C．d→b→e→c→a     D．e→d→b→c→a
67．Most people in the USA can digest milk becauseB．
A．they have strong stomachs                  B．their ancestors were Europeans
C．that's where milk drinking stinted        D．farmers raise a lot of cows there
68．Which of the following is LEAST likely to appear on the menu in a Japanese restaurant？A

8．It might have been a really bad stressful day，feeling trapped inside by the cold and snow which surrounded us．My husband was the first to shift his consciousness．He dressed accordingly and announced that he was going outside to build a giant snowman．
At first he stood alone，piling massive amounts of snow．Soon after a neighbor joined in my husband's quest to embrace the opportunity the winter presented．Maintaining less than desirable attitudes，we reluctantly put on our snow gear（用具） and headed outside．It wasn't long before we were smiling and enjoying the abundance of snow that Mother Nature had provided．Others came to our yard one by one to give a hand in the making of our giant snowman．
In the end we all stood back and marveled at what we had created．He was eleven feet high，twenty-five feet around at the base and decorated with many household items supplied by various families．There he stood，our glorious，gigantic （巨人般的） snowman．
People drove by and smiled．Some even stopped to enjoy his existence．The spirit that went into creating him seemed to catch on and we all enjoyed it while the cold temperatures allowed．
With the passing of time，the spring made its way back into our yard and the snowman changed form considerably．In a final effort to save what we created for just a little bit longer somebody stopped by and changed the snowman's remains to look like a rabbit．
As I prepared for the start of another week，I decided to check my email before going to bed．I found a curious message that contained the subject line：enjoy the snowman．I decided to read the message even though I did not recognize who sent it．The words it contained melted my heart．
The email said：…your neighbor looks on in disbelief!I am sure you people are enjoying the sounds and smells，along with sights of spring．The energy displayed in Mr．Snowman or Ms，is filled with vigor and joyous energy．You and your family keep it up，as this is what the world needs now．Love sweet love．More power to you and your loved ones，keep sharing with the world around．
Perhaps it was more than snowman we built that day．I'd like to agree that it was．The message seems clear．Our circumstances will turn out to be what we make of them．The possibilities are endless and the choice is ours．

66．How did the author plan to spend that cold day at first？B
A．By having a busy day．   B．By staying at home．
C．By building a snowman．  D．By visiting neighbors．
67．The reason for her husband to make a snowman was thatC．
A．he had to please his neighbors
B．he was better at it than others
C．he wanted to cheer himself up
D．he must get the last chance before spring
68．From the passage we can know that the snowmanB．
A．was built only by the author's family
B．was surprisingly big in size
C．made people more forgiving
D．made building snowman popular
69．Which of the following statements on the email is not true？B
A．It was probably form a neighbor who didn't build the snowman that day
B．It was mainly written to share joys for the coming of spring
C．The writer of the email encouraged the author to keep being vigorous and joyous．
D．The author was deeply touched and inspired by its words．
70．According to the author，D．
A．there are many chances in our life
B．choices are more practical than possibilities
C．we must have our own ideas about our decision
D．we can determine our way of life through our choice．
18．Apparently，we are safe neither at home nor in the business office．We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects．These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one's house．They are released（set free）from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines．As the water is moving．these chemicals are released into the air and then breathed in．Once inside our bodies，they start to affect our health．
         Does this mean we should stop bathing？No，say the scientists，but we should put all pollution into perspective．Activities at home such as the burning of coal，cooking oil，or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic．New tugs，bedding，and even clothing give off that"new smell，"which is a sure sign of chemicals．In the office，newly applied paint，newly purchased telephones and other telecommunications equipment，and computers release polluting chemicals，too．As offices and homes often have inadequate ventilation （通风），these chemicals can build up to become health problems．Their poisonous effects are only now being slowly recognized．
         These facts suggest that，at a minimum，proper airing of newly purchased goods with an obvious chemical smell is a wise warning．Home and office windows should be opened during good weather．Even one's car needs to be ventilated as well while in the garage．
         We need further research to understand better other potential health dangers，too．For example，the effects of overcrowding of schools （carbon dioxide build-up ），the factory work environment （ an endless list of potentially dangerous substances ），and even home heating and cooling （the air conditioner may be our enemies，not our friends） have only recently started to come to light．Until we understand the effects of our new technological environment better，we can only hope that"there is no place like home．"
64．What is the main idea of the first paragraph？B
A．The air we breathe in is harmful．
B．The water in everyday use is unsafe．
C．Chemicals are added to the drinking water．
D．Chemicals are released in the running water．
65．In Paragraph 2，the underlined sentence means thatC．
A．bathing should be done with caution
B．homes and offices should be aired often
C．any pollution should be taken into consideration
D．we should prevent any pollution from doing harm to us
66．What is the purpose of the passage？C
A．To call on us to guard our water．
B．To show us that no place is like home．
C．To make us aware of the pollution around us．
D．To argue that neither homes nor offices are safe．
5．Someday a stranger will read your e-mail without your permission or scan the websites you've visited．Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits．
If fact，it's likely that some of these things have already happened to you．Who would watch you without your permission？It might be a spouse，a girlfriend，a marketing company，a boss，a cup or a criminal．Whoever it is，they will see you in a way you never intended to be seen-21st century is the equal of being caught naked．
Psychologists tell us boundaries（dividing line） are healthy，and that it's important to reveal yourself to friends，family and lovers in stages，at appropriate times．But few boundaries remain．The digital bread pieces you leave everywhere make it easy for strangers to reconstruct who you are，where you are and what you like．In some cases，a simple Google search can reveal what you think．Like it or not，increasingly  we live in a world where you simply cannot keep a secret．The key question is：Does that matter？
When opinion polls（民意测验）ask Americans about privacy，most say they are concerned about losing it．a survey found an overwhelming（very large）pessimism about privacy，with 60percent of respondents saying they feel their privacy is"slipping away，and that bothers me．"
But people say one thing and do another．Only a tiny part of Americans change any behaviors in an effort t protect their privacy．Few people turn down a tollbooths（收费站）to avoid using the EZ-Pass system that can track automobile movements．And few turn down supermarket loyalty cards．Privacy economist Alissanfro Acquisti has a series of tests that reveal that people will give personal information like Social Security numbers just to get their hands on a pitiful 50-cent-off coupon（优惠券）．
But privacy does matter-at least sometimes．It's like health； when you have it，you don't notice it．Only when it's gone do you wish you'd done more to protect it．

63．What would psychologists advise on the relationship between friends？C
A．Friends should open their hearts to each other．
B．Friends should always be faithful to each other
C．There should be a distance even between friends
D．There should be fewer quarrels between friends．
64．Why does the author say"we live in a world where you simply cannot keep a secret"？B
A．Modern society has finally developed into an open society
B．People leave traces around when using modern technology
C．There are always people who are curious about other's affairs
D．Many search engines profit by revealing people's identities
65．What do most Americans do about privacy protection？D
A．They change behaviors that might disclose their identity
B．They use various loyalty cards for business deals．
C．They rely more and more on electronic devices
D．They talk a lot but hardly do anything about it．
66．According to the passage，privacy is like health becauseD．
A．people will make every effort to keep it
B．its importance is rarely understood
C．it is something that can easily be lost
D．people don't value it until they lose it．
2．Two new studies suggest that modern running shoes could increase the risk of injuries to runners．
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week．The runners were observed on a treadmill machine．Sometimes they wore running shoes．Other times they ran barefoot．
Researchers from the JKM Technologies Company in Virginia，the University of Virginia and the University of Colorado did the study．
They found that running shoes create more stress that could damage knees，hips and ankle joints than running barefoot．They observed that the effect was even greater than the effect reported earlier for walking in high heels．
The study appeared in the official scientific journal of the American Academy of Physical Medicine．
The other study appeared in the journal Nature．It compared runners in the United States and Kenya．The researchers were from Harvard University in Massachusetts，Moi University in Kenya and the University of Glasgow in Scotland．
They divided the runners into three groups．One group had always run shoeless．Another group had always run with shoes．And the third group had changed to shoeless running．
Runners who wear shoes usually come down heel first．That puts great force on the back of the foot．But the study found that barefoot runners generally land on the front or middle of their foot．That way they ease into their landing and avoid striking their heel．
Harvard's Daniel Lieberman led the study．He says the way most running shoes are designed may explain why those who wear them land on their heels．The heel of the shoe is bigger and heavier than other parts of the shoe，so it would seem more likely to come down first．Also，the heel generally has thick material under it to soften landings．

64．How many organizations are involved in the two studies？D
A．Three．          B．Four．
C．Five．           D．Six．
65．Why do running shoes increase the risk of injuries to runners？C
A．They create more stress．
B．They're too big and heavy．
C．They can affect the way the runners run．
D．Their heels can soften landings．
66．What can we learn from the text？A
A．Most running shoes are designed improperly．
B．The design of high heels is better than that of running shoes．
C．No one will run with running shoes in the future．
D．Both of the studies are done in America．
67．How did the researchers do the two studies？B
A．By practising．       B．By comparing．
C．By questioning．      D．By reasoning．
3．Trains with the first letter D or Z can run __________ a speed of more than 200kilometers an hour when it travels __________ the desert．（　　）
A．with； crossB．in； throughC．at； acrossD．for； in
