PALO ALTO, California------"Switching off the television may help prevent children from getting fatter------ even if they do not change their diet or increase the amount they exercise," US researchers said last week.
　　A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet.
　　"The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician(兒科專家) at Stanford University.
　　"American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said.
　　In the study, presented this week to the Pediatric Academic Societies‘ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
　　Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
　　"One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said.
　　"Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said.
小題1:The author tries to tell us in the first two paragraphs that ________.
A．children will get fatter if they eat too much

閱讀下面的短文，并根據(jù)短文后的要求答題（請注意問題后的字?jǐn)?shù)要求）。
[1] I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day. But I became invisible, absent from the conversation.
[2] The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Recently I was in a car with three friends. The driver told us to be quiet because he could not hear the person on the other end of his cell phone. There we were, four friends going down the highway, unable to talk to one another because of a tool designed to make communication easier.
[3]Why is it that the more connected we get, ________________________ ? Every advance in communications technology is a hurt to the closeness of human interaction (互動). With e-mail and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone.
[4] More and more, l find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up because I didn’t really have time to talk. The industry devoted to helping me keep in touch is making me lonelier.
[5] So I've put myself on technology restriction: no instant messaging with people who live near me, no cell-phoning in the presence of friends, no letting the voice mail pick up when I' m home.

A lazy Susan is an addition to a table, which is designed to assist in moving food from one person to another while dining. This is accomplished through the use of a turntable(轉(zhuǎn)盤), which usually moves the food in a circle when pushed by those at table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place as the lazy Susan is turned about.
A lazy Susan may also be a part of a kitchen cabinet. One may spin the lazy Susan in order to find certain goods stored in it. From the outside, a lazy Susan appears to be two cabinets. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
Whether the lazy Susan is on a tabletop or within a cabinet, it can be made of a variety of materials. Most commonly, a lazy Susan is made of either plastic, wood or glass. Some people believe that Thomas Jefferson invented the lazy Susan, though it was referred to as a dumb waiter(上菜升降架) at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph(留聲機(jī)), which later developed into the lazy Susan.
Regardless of who invented it, it wasn’t until 1917 that the term lazy Susan was created in an advertisement for the invention. In Britain, however, the term dumb waiter is still used rather than the term lazy Susan. The reason for the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.
小題1: According to the passage, a lazy Susan _____.
A．is a person who serves food at table
B．is a waitress who helps move dinner tables
C．is an additional round table in a dining room
D．is a turntable that passes food around the table
小題2:Which of the following is NOT true of the lazy Susan?
A．On a tabletop, it is convenient for people to have dinner.
B．Within a cupboard, it is easy for people to see what is inside.
C．The turntable was invented in 1917.
D．It can be made of many kinds of materials.
小題3:Why did Jefferson’s daughter complain she was served last when having meals?
A．Because she was too lazy.
B．Because she was the youngest.
C．Because the table was too tall for her.
D．Because the table couldn’t move food for her.
小題4: From the passage, we can know that _____.
A．the lazy Susan was invented earlier than the phonograph
B．Susan was the name of Jefferson’s and Edison’s daughter
C．Jefferson and Edison invented the lazy Susan at the same time
D．When people talk about a lazy waitress they use the term “Susan”
小題5:What is the main idea of the passage?
A．What is a lazy Susan?
B．When was the lazy Susan created?
C．Why do inventions come from the daily life?
D．How was “dumb waiter” replaced by “l(fā)azy Susan”?

Do you think it is ever a good idea for a teenager to have a credit card?
My kids watch closely as I swipe the card through the register．They’ve seen me do it hundreds, thousands of times．Cool．They are itching to swipe it through the machine themselves． When we walk out of the store with our groceries or pet food, or whatever, it’s almost as though money has not changed hands, painless, easy．
So it shouldn’t be shocking to discover that teenagers are becoming card carrying consumers in their own right．The question is, should they?
While some argue it’s best to teach kids how to use a credit card while still living under the family roof, not everyone agrees． Dave Ramsey, financial expert says getting a credit card for your teenager is actually, “an excellent way to teach him or her to be financially irresponsible．”
Now parents are required to co-sign on credit cards for children under 21．“If their name is on the credit card, then the parent may say, ‘Hey, my name is on this．Don’t get me into trouble,” says Mary Beth Pinto, a marketing professor．“When parents were the co-obligors（共同借貸人），the children caused less debt．If the parents are the co-obligors, the tendency is that the parents were explaining how to use the cards．” Still, Pinto believes parents should start the process much earlier．“Yes, there has to be teaching going on and it has to start when they’re younger． You’re not going to get rid of credit cards．They are here to stay． You have to have them． You can’t fight progress,” Pinto said．
Ramsey, however, disagrees．“Throwing teens into a pool of （credit）sharks is a sure way to guarantee a life-time of heartache,” he said．“You can make online purchases and rent a car with a credit card．Of course, you must have money in your bank account before you can make a purchase with a credit card．But paying for things with money is what you are supposed to do．”
小題1:The author mentioned her experience in Para 2 mainly to______．
A．prove the convenience of using credit cards
B．tell what impression credit cards leave on kids
C．give advice on using credit cards wisely
D．explain the pleasure credit cards bring to customers
小題2:The underlined word in Para 2 can be replaced by __________．
A．eagerB．a(chǎn)fraidC．embarrassedD．thankful
小題3:What’s Ramsey’s attitude towards teens’ using credit cards?
A．He feels it is worth a try
B．He is very supportive
C．He is strongly against it
D．He considers it as a pleasant experience
小題4:Pinto will most likely agree that __________．
A．parents should let teens own their credit cards earlier
B．you shouldn’t be in control of credit cards
C．it is never good for anyone to get a credit card
D．learning to use credit cards is practical

Scientists made a great break through this year in England when the first "test tube" baby was born．The birth was the result of many years of research by doctors．The doctors did the research in groups to help the women who cannot conceive a baby in the normal way．
What happened when the baby was born "from a test tube"? Well, the baby did not literally grow in a test tube．The first stage of the process was that the egg from the woman and the sperm from the man were put together in the test tube．After all, the embryo was put into the womb of a woman．This process was difficult．But it was successful, so the baby was eventually born, like any other, from a woman, only the woman wasn't the baby's real mother, but a sort of "carrier" of a baby produced by another couple．
Obviously, this method is to help to couples who can't have children because of physical problems in the woman．But very difficult moral problems arise in the kind of situation．Take it for instance, a case that happened this year．A couple who wanted a baby advertised for a woman to have a child by the father of the couple．They offered the woman a lot of money．The woman was made pregnant by artificial insemination; in this case, the woman "employed" to bear the child was its real mother．When the baby was born, the woman refused to give it back to the couple．But, in the eyes of the law, the woman had a right to keep the children because she was its biological mother．
You could argue that we should change the law to deal with this kind of situation．In earlier times, there were always healthy babies needing adoption, because family planning methods were not so effective as they are now．These days, however, most of the children who can be adopted are over six years old, often handicapped in some way．So a couple who want a young healthy baby cannot always adopt one, this is why the "test tube" baby is in demand．But is it normally right to use this method? Should we temper with nature in this way? Even if we change the law, would this be the right step to take ?
小題1:The birth of the first "test-tube" baby is a great advance _____．
A．on medical science
B．in birth control
C．on the research for babies
D．in the lives of married women
小題2:When we say a baby was born "from a test-tube", we mean_____ ．
A．the baby didn't develop in the womb of a woman
B．the baby has no biological parents
C．the embryo was formed in the test tube
D．the baby grew in the test-tube before it was born
小題3:According to the law, who has right to keep the baby produced by the artificial method?
A．The couple who want a baby．
B．The biological mother of the child．
C．The person who pays the money to the real mother．
D．The father who advertises for a biological mother．
小題4:According to the passage, people need "test-tube baby" because_____ ．
A．family planning methods are not effective．
B．they can't always adopt a young healthy baby
C．they are unwilling to adopt a child．
D．there are so many babies needing adoption．

With the development of society and economy, animals and their habitats are getting pushed aside as households decrease in size and increase in number.
Small numbers of people per household on average use more energy and goods per person. Greater numbers of households require more natural resources for construction. The possible result of this problem may be insufficient natural resources to meet consumer demand without endangering habitats important to biodiversity.
Personal freedom and social choice may come at huge environmental cost. Direct costs include visible damage to animal habitats and plant life. Indirect costs include the release of more greenhouse gases.
The effects of such “personal freedom and social choice” have already surfaced in south-west China’s Wolong Nature Reserve. In Wolong, they found that a reduced average household size was directly tied to an increase in homes, and thus an increase in the amount of firewood consumed for cooking and heating. The rise in wood fuel use has contributed to disappearance of forests and to the loss of habitats for giant pandas. 
Curious about whether other parts of the world were experiencing similar phenomena, they got the support of a team of researchers including Stanford’s Paul Ehrlich, well-known for his population studies, to find out the household dynamics in 141 countries between 1985 and 2000. Their study proved that the difficult choice of Wolong is part of a global trend.
In the 76 countries considered biodiversity “hotspots”, such as the United States, Brazil, Australia, and Kenya, the number of households grew by 3.1% every year, while the population increased just 1.8%. Meanwhile, the number of people per home dropped from 4.7 to 4.0. The decline in household size has resulted in 155 million additional households in hotspot countries, almost always limiting biodiversity.
In the 10 non-hotspot countries — those without high-density areas of animal and plant species — similar results were found, though on a lesser scale. Even in countries experiencing population decline, such as New Zealand, the number of households still increased because of a reduction in household size.
小題1:What does the underlined word “insufficient” mean?
A．Plenty of.B．Not enough.C．Abundant.D．Little.
小題2:It can be learned from the passage that China’s Wolong Nature Reserve_____
A．is facing the same threat as many other parts of the world
B．sets a good example in protecting animals
C．is a place where giant pandas and their habitats are not affected
D．is a place where animals and their habitats are seriously damaged
小題3:Which of the following is best supported by the last two paragraphs?
A．Biodiversity is better kept in countries with smaller populations.
B．Biodiversity is better kept in hotspot countries.
C．The threat to nature from reduction in household size is a worldwide problem.
D．Both hotspot countries and non-hotspot countries face the threat of the same scale.
小題4: What does the passage mainly talk about?
A．Reduced household size leads to an increase in household number.
B．Modern homes consume more natural resources.
C．How to meet consumer demand without endangering animals and their habitats.
D．Reduction in household size as well as increase in household number threatens nature.
