1、U. S. to Start $3. 2 Billion Child Health Study in January
A study that will cost $3. 2 billion and last more than two decades to track the health of100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.
Officials from the U. S. government＇s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.
The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.
Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.
Officials said more than $200 million has been spent already and the study is projected to cost$3. 2 billion.
"We anticipate that in the long term , what we learn from the study will result in a significant savings in the nation＇s health care costs," Dr. Duane Alexander, who heads the NIH＇s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.
The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.
Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheid of the NIH, who heads the study.
The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.
It is expected that through the study the nation＇s health care costs____.【单选题】

A.will be lowered in the long run.

B.will be significantly increased.

答案解析:短文的第6段说到，预计从长远的角度讲，此项研究将有利于国家卫生保健费用开支的节约。

2、Indian＇s Names
Each Indian was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.
The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-of-a Horse. So an Indian＇s name told his record or described the kind of man he was.
A man was given many chances to improve his name, however, if in a later battle he was brave in fighting against the enemy, he was given a better name. Some of our great fighters had as many as twelve names, all good and each better than the last.
An Indian＇s names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.
Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed. I know of only three or four times when this happened. It is the rarest honor for a person -the honor of assuming his father＇s name.
An Indian could be given the second name by____.【单选题】

A.his father

B.the enemy

C.the chief of the tribe

D.his childhood friends

正确答案:D

答案解析:birth name是出生时就取的，而且应该保留直到大了以后可以自己赢得一个名字。但是儿时的玩伴会给他一个a name of their own，因此选D。

3、Electric Backpack
Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don＇t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.
Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack＇s electricity-generating feature could dramatically reduce the amount of a wearer＇s load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9, Science.
The backpack＇s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer＇s back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7. 4 watts.
Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack＇s oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.
The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren＇t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!
What is the most important feature of the backpack invented by Lawrence C. Rome and his colleagues?【单选题】

A.It produces electricity for electronic devices while the wearer walks.

B.It can be used as cell phones, GPS in the military actions or field studies.

C.It is small and convenient.

D.It is light and easy to carry.

正确答案:A

答案解析:第2段的第1句说，Lawrence C. Rome及其同事们发明的这种背包，当背着背包走路时，会有电能产生。该段最后一句告诉我们，背包的这种性能可减少背包的重量，因为不必携带备用电池。

4、Shopping at Second - hand Clothing Stores
When 33 years old Pete Barth was in college, shopping at second - hand clothing stores was just something he did－"like changing the tires on his car." He looked at his budget and decided he could save a lot of money by shopping for clothes at thrift shops.
"Even new clothes are fairly disposable (用后即丢掉的) and wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."
Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons for shopping for second - hand clothing. Some people, like him, shop to save money. Some shop for a crazy - looking shirt. And some shop as a means of conserving energy and helping the environment.
Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, for her, shopping at thrift shops is a way to help the environment.
"When my daughter was little, we looked at it as recycling," Akins said: "Also, why pay 30 dollars for a new coat when you can get another one for a lot less?"
Akins said that the SA has shops all over the US－"some as big as department stores". All of the clothes are donated (捐赠), and when they have a surplus (盈余), they＇ll have "stuff a bag" specials, where customers can fill a grocery sack with clothes for only 5 or 10 dollars.
Julia Stocum, 22, points out, however, that the huge amount of second - hand clothing in the US is the result of American wastefulness.
"I＇d say that second - hand stores are the result of our wasteful, materialistic culture," said Slocum, who works for a pro - conservation organization, the center of a New American Dream. "Thrift shops prevent waste from going to landfills (垃圾填埋场), They give clothing a second life and provide cheaper clothing for those who can＇t afford to buy new ones and generate (创造) income for charities. They also provide a way for the wealthy and middle classes to shed (摆脱) the guilt for their level of consumption."
What does Akins do? ____【单选题】

A.She is a soldier.

B.She is an accountant.

C.She is a saleswoman.

D.She is a road sweeper.

正确答案:B

答案解析:本题难度不大，答案依据不难找到。带着题干信息到文章定位，认真阅读文章第四段。第四段第一句话谈到，“Akins是旧货店的一名会计”，所以答案是B。

5、Stop Eating Too much
"Clean your plate!"and" Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent or grandparent. Often, it＇s accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of saying "clean the plate", perhaps we should save some food for tomorrow.
According to news reports, US restaurants are partly to blame for the growing bellies(肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.
Barbara Rolls, a nutrition (营养) professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline(腰围) began to expand.
Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can＇t afford fine dining still prefer large portions. Seventy percent of those earn at least $ 150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25, 000 want smaller.
It＇s not that working class Americans don＇t want to eat healthy. It＇s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money for next year＇s Christmas presents.(2008年)
Why do American restaurants serve large portions?
【单选题】

A.Because Americans have big bellies.

B.Because Americans associate quantity with value.

C.Because Americans are good eaters.

D.Because Americans are too weak.

正确答案:B

答案解析:题干问“为什么美国餐馆提供的食物量大”。参见文章第二段，传统上美国人把东西值不值跟数量联系在一起，因此餐厅给的食物分量大，乐于让顾客们抱怨饭菜给得太多而不乐于让他们抱怨饭菜给得太少。故正确答案为B。
