Why do smokers tend to weigh less than nonsmokers and gain weight when they
give up the habit?
Contrary to “common knowledge”, nonsmokers do not generally eat more than
smokers, nor do they exercise less, studies find. Research performed on smokers at
rest indicates that nicotine (尼古丁) itself can increase basal metabolic (新陈代谢的)
rates, meaning smokers burn more energy than nonsmokers during periods of
inactivity. But surveys suggest most smokers smoke not while completely at rest, but
while performing light activities such as desk work that can increase metabolic rates
by two or three times. Unless nicotine’s
metabolic effects increase proportionally
with metabolic rates, its influence on weight might be insignificant.
ffects on body-fuel consumption indeed increase
Now a study shows that nicotine’s e
proportionally with increases in activity. “These results indicate that the metabolic
effect of nicotine may play a greater part in accounting for body-weight differences
between smokers and nonsmokers than w as previously believed,” says Kenneth A.
Perkins and his colleagues at the University of Pittsburgh School of Medicine.
The researchers gave a nicotine nose spray to individuals performing light work — in
this case riding an exercise bicycle modified to allow easy riding while subjects
remain seated in a comfortable armchair. The activity raised resting metabolic rates
two to three times.
By analyzing air breathed out, the researchers calculated energy consumption in the
armchair bicyclists before and after giving the nose spray and compared the relative
changes with subjects in the control group given placebo (（试验药物用的）无效对
照剂) nose sprays. Relative to their baseline bicycle expenditures, individuals in the
nicotine group expended considerably more energy than did those in control group
while doing the same amount of work. With nicotine, Perkins says, “It’s as if the is becoming much less efficient in using its stored energy.”
While the results may seem discouraging to smokers who’d like to quit without
gaining weight, Perkins notes that walking an extra mile a day should make up for
the difference in metabolic efficiency. And he says smokers would have to gain “more than 50 pounds” to counterbalance the health risks of continued smoking.
1. What might “common knowledge” say about smokers and nonsmokers?
A) Smokers eat more and exercise more than nonsmokers.
B) Smokers eat less and exercise less than nonsmokers.
C) Smokers eat less and exercise more than nonsmokers.

You will have 15 minutes to go over the passage quickly and decide whether each of the statements is true or false, or that the information is not given in the passage. Then mark the answer on the Answer Sheet. Renewable Energy How does energy use affect the environment? All forms of electricity generation have some level of environmental impact. However, clean energy technologies, including renewable energy and combined heat and power, have fewer impacts than other sources of electricity generation. To learn about the environmental impacts of electricity generation technologies, click on an energy source below. How clean is the electricity I use? In the United States, electricity is generated in many different ways, with a wide variation in environmental impact. Traditional methods of electricity production contribute to air quality problems and the risk of global climate change. With the advent of electric customer choice, many electricity customers can now choose the source of their electricity. In fact, you might now have the option of choosing cleaner, more environmentally friendly sources of energy. How can I make a difference? The energy decisions we make every day can encourage the development of new power sources, save natural resources, and help ensure that the quality of our environment is preserved. In many parts of the country, consumers now have the opportunity to choose the source of the power that is delivered to their home or business—including energy derived from renewable sources. "Renewable energy" generally refers to electricity supplied from renewable energy sources, such as wind and solar power (energy supplied by the sun), geothermal (energy created from the extreme heat contained in liquid rock—called magma（岩浆）—within the Earth's core), hydropower (energy derived from the movement of water as it flows downstream), and various forms of biomass (fuel from sources such as trees, wood and agricultural wastes and fuel crops). These energy sources are considered renewable because they are continuously replenished on the Earth. In addition, mobile sources of air pollution—such as cars, trucks, trains and lawnmowers—also contribute to air pollution nationwide and are an important source of air pollution in many urban areas. Hydrogen Energy Using hydrogen energy could help address many concerns facing our nation and our world. We believe hydrogen can contribute to resolving these issues for these reasons:

Unit 1 Education: A Transformation of the Soul 3 I went on to college, of course, as everyone told me to do. College is how you become an earner, they told me. My major that first semester was International Relations. I liked the woman I envisioned myself as in this field – a diplomat, a savvy citizen of the world. But gradually I began to realize that this person was not someone I bore any resemblance to. She was, rather, a clone of the well-educated, well-moneyed ideal my teacher had presented to me years ago. This woman had earning potential; she was smart and worldly. But she was not someone I would become. She had

大学英语B 阅读理解答案
阅读理解 B 42、Martin Luther King was a black minister, who became a great leader of the civil rights movement in the 1950s and 1960s. King was born on January 15, 1929 in Atlanta, Georgia. When he was young, he was strongly influenced by Thoreau and Indian leader Mahatma Gandhi's idea of non-violent resistance. Having received a Ph. D (Doctor of Philosophy) from Boston University, he became a political and religious leader of the non-violent civil relights movement in 1955. On August 28, 1963, he led over 250,000 Americans on a march in Washington D.C. to fight for the Civil Rights Law to guarantee equality for all people, and delivered his best known speech "I Have a Dream" before the Lincoln Memorial. The "dream" is a dream of brotherly love and equality for the Black and White. Thus, he was awarded the Nobel Prize for peace in 1964, but he was murdered four years later. Though he died, he was greatly respected and loved by the Americans, both the white and the black. By vote of Congress in 1968, the third Monday of every January is now a federal holiday in Luther King's honor. He lives in people's hearts forever. (1)、Martin Luther King was murdered when he was 39 years old. A：T B：F 答案：A (2)、Martin Luther King was a black minister only. A：T B：F 答案：B (3)、Martin Luther King's Day has been a federal holiday for more than 40 years. A：T B：F 答案：A (4)、The underlined word "delivered" in the second paragraph could be replaced by "gave".

He is going to sell it because it is haunted (闹鬼的). He told me that he could not go to sleep one night because he heard a strange noise coming from the bar. The next morning, he found that the doors had been blocked by chairs and the furniture had been moved. Though Mr. James had turned the lights off before he went to bed, they were on in the morning. He also said that he had found five empty whisky bottles which the ghost (鬼) must have drunk the night before. When I suggested that some villagers must have come in for a free drink, he shook his head. The villagers have told him that they will not accept it even if he gives it away.

A：T B：F 答案：B 44、Great changes have been made in family life because of science and industry. In the past, when more Americans lived on farms, the typical family had many children. In a farm family, parents and their children often lived with grandparents. Often, too, uncles and aunts lived nearby. But when industry became more important than agriculture in American life, families became smaller because industry requires workers who are ready and able to move off the land and to move again whenever necessary. And large families can not be moved from place to place as smaller families can. So, at present people tend to have smaller families. In the future, because of industrialization, a typical family will be required to move even more often than now, so families will be even smaller. The typical family may remain childless and consists only of a man and a woman. A small number of families may take child raising as their chief work. At the same time they may also raise other people's children, leaving those families free to move from job to job. (1)、The passage discusses influence of science and industry on American families. A：T B：F 答案：A (2)、Families of the past, the present and the future are described in the passage. A：T B：F 答案：A (3)、People no longer want to have children. A：T B：F 答案：B (4)、Grandparents will take the chief responsibility of raising children in the future. A：T B：F 答案：B (5)、Large families cannot fit in with a highly industrialized society. A：T B：F 答案：A 45、My husband had just bought a new washing machine for me. I decided to use it and I washed a lot of things. Everything worked well, but I found one of my husband's socks missing. I looked everywhere for it, but I couldn't find it anywhere. The next morning, I got ready for school as usual. When the bell rang, the students came in. I greeted them first and then told them what we were going to do that day. When I turned around to write on the blackboard, the class broke out a roar! They laughed and laughed. They laughed so much, in fact, that I was afraid the headmaster would be into seeing all this. I asked the class to stop, but the more I talked, the more they laughed. I decided to pay no attention to them and I continued to write on the blackboard. When I did this, they roared even more. Finally, the teacher who had the room next to mine came in to see what all the laughter was about. When he came in, he started laughing, too!

大学英语口语考试试题及答案
以下为爱麟霖/(Curlylin)倾情奉献，需要的朋友可以参考一下 7. Friendship (Listening and Speaking Course, Unit 3; Integrated Course, Unit 2) 1) Do you have many friends? What kind of people do you want to make friends with? Why? Yes. I’d like to make friends with loyal people. In my opinion,a friend is a person who can share his/hers happiness with you, who can lend you a shoulder when you cry,who can give you a hand when you are in trouble without asking for anything in return. In a word,a friend in need is a friend indeed, I think a loyal people can do the things which were mentioned above for his/hers true friend. So I prefer to make friends with loyal people, and I also believe I am a loyal people who you can make friends with. 2) How do you make friends? Please comment on “a friend you buy isn’t worth the price”. First,I’d like to talk to him to find out whether we have the same interest with each other. If the answer is YES,then we have the foundation to develop a friendship. The next days, all we need to do is to treat each other by heart and soul. 3) How valuable is friendship in a person’s life? How can we keep friendship alive? As for me, I regard friendship as a very important part in my life.Just imagine a life,there’s no one to be your friend. What life could be if you had no friend to talk to , no friend to comfore you and cheer you up when you were having a hard time,no friend to lend you a hand when you needed help …… Life without friends is unthinkable ... We have to do hard work to build up and sustain our friendship. First, let your friends know that you really care about them.It’s important to give some cues to your friends. Be sure your friend knows that she is cared about.Second,try to be with your friends when they are in trouble when they need you. Keeping friendship alive is not only to say some sweet words,but need some real action. 4) What does friendship mean to you? What kind of friends do you think are true friends? It's a fantastic experience in whole of my life. Friendship to me is what water to fish.I can't live without a real friend. 2问见（1） 5) How can we get along well with other people? To begin with, we need to be honest with others and always say what we mean. Lies will surely make people stay far away from us in the long run. After all,honesty is the best policy. Second, we have to be humble enough. If we are proud in public, we can hardly win other's respect, not to mention "friendship" . Finally, we must not be selfish. We should learn how to show concern for others. As long as we abide[?'ba?d] by what is mentioned above, we will find it easy to get along well with others.

Unit 1 Education: A Transformation of the Soul 1On my first day of high school, my teacher showed the class a Power Point presentation entitled The Value of Education. The first slide read simply this: ―Education = $‖. I felt uncomfortable, not knowing exactly why. 2 Education, throughout my high school experience, continued to be described to me like this: college means a diploma. A diploma means a better job. A better job means more money. More money means a good life. But I wondered who had decided the criteria for a ―better‖ job and a ―good‖ life. It all seemed so mathematical. Education was presented to me as an equation equaling a person I had not chosen to be. 重点单词的句子翻译： 1.她读了一首题为《想起你》的诗。(entitle) 2.他给这本书取名为《野性的爱》。(entitle) 3.教育的关键在于激励和享受，而不是一所学校或一个大学文凭。(diploma) 4.那青年用了3 年的时间取得研究生文凭。(diploma) 5.我自己成功的标准是能够努力工作和快乐生活。(criteria) 3 I went on to college, of course, as everyone told me to do. College is how you become an earner, they told me. My major that first semester was International Relations.

大学英语一阅读理解 一、阅读理解（共505题,共101分） 1. Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled—to $1. 01 per pack—smokers have jammed telephone “quit lines” acro ss the country seeking to kick the habit. This is not a surprise to public health advocates. They’ve studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase. The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely. In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost ＄10.06 at one drugstore Wednesday. Charleston, S, C., where the 7-cent-a-pack tax is the lowest in the nation. The price was $4. 78. The influence is obvious. In New York, high school smoking hit a new low in the latest surveys—13.8%, far below the national average. By comparison, 26% of high school students smoke in Kentucky, Other low-tax states have similarly depressing teen-smoking records. Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans “who choose to smoke.” That’s true, But there is more reason in keeping future generations of low-income workers from getting hooked in the first place, As for today’s adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better. （1分） (1) The text is mainly about___________. （0.2分） A.the price of cigarettes B.the rate of teen smoking C.the effect of tobacco tax increase D.the differences in tobacco tax rate 标准答案：C (2) What does the author think is a surprise? （0.2分） A.Teen smokers are price sensitive.
