The reasons for a person’s becoming an alcoholic have often been debated by psychologists and other scientists. But recent studies suggest that the problem of alcoholism(酒精中毒) should also be the focus of investigation by biologists.
While such things as hard jobs, boredom, and unhappiness can lead to alcoholism, researchers at a prominent university have found that there may also be a genetic factor involved in alcoholism. In the study, children of alcoholic parents were surveyed. The result showed that the children of alcoholic parents were more likely to become alcoholics themselves than were children of non-drinking parents.
This evidence in itself is not conclusive(令人確信的)about anything. After all, it may be the constant exposure(接觸)and easy access to alcohol that cause the children of alcoholics to become alcoholics themselves. But there is more evidence. The study found that children born of alcoholic parents but raised by non-drinking foster(撫養(yǎng)的)parents also were susceptible to alcoholism. This group of offspring(后代)was more likely to take up drinking than youngsters who were born of and raised by non-drinking parents.
Other evidence found in the study suggests that environment does not play as important a role in the development of alcoholism as had been previously thought. The study found that the likelihood of alcoholism was better predicted from the characteristics of the parents than from such environmental characteristics as type of job or level of income.
63. What is the main point of the passage?
A. To describe the environment in the development of alcoholism.                                
B. To study the psychological factor in the development of alcoholism.
C. To describe how the children of alcoholic parents become alcoholics themselves.        
D. To describe the close link between genetic make-up and alcoholism.
64. According to the passage, what can bring about alcoholism?
A. Biologists’ investigation.                       B. Non-drinking parents.
C. Hard jobs, boredom and unhappiness.             D. Foster parents’ raising.
65. According to the findings of the study, who would be the most likely to become an alcoholic?  
A. A person who had a hard job.
B. A person who was born of alcoholic parents.
C. A person who was raised by drinking foster parents.
D. A person who was born of and raised by non-drinking parents.
66. According to the passage, what should the problem of alcoholism be treated as?
A. A psychological problem.
B. An environmental problem.
C. A biological problem.
D. An educational problem.

There are thousands of products of all colors and shapes in a supermarket, making you believe that they are worth a try. How? Packaging (包裝)is the silent but persuading salesman.
There on the shelves, each bottle, can, box, and jar has been carefully designed and measured to speak to the inner self of the consumer(消費者), so that is buying not only a product but also his belief in life. Scientists have studied consumer behavior recently and found that the look of the package has a great effect on the “quality” of the product and on how well it sells, because “Consumers generally cannot tell between a product and its package. Many products are packages and many packages are products,” as Louis Cheskin, the first social scientist studying consumers’ feeling for packaging, noticed.
Colors are one of the best tools in packaging. Studies of eye movement have shown that colors draw human attention quickly. Take V8 for example. For many years, the bright red color of tomatoes and carrots on the thin bottle makes you feel that it is very good for your body. And the word “green” today can keep food prices going up.
Shapes are another attraction. Circles often suggest happiness and peacefulness, because these shapes are pleasing to both the eye and the heart. That’s why the round yellow M signs of McDonald’s are inviting to both young and old.
This new consumer response(反應(yīng))to the colors and shapes of packages reminds producers and sellers that people buy to satisfy both body and soul.
60.According to the passage, ______ seems to be able to persuade a consumer to buy the product.
A.the pleasing color of the package    B.the special taste of the product
C.the strange shape of the package     D.the belief in the product
61.If a package or a product is round in shape, it can ________.
A.bring excitement to the consumers  B.a(chǎn)ttract the consumers’ attention
C.catch the eye movement of the consumers   D.produce a happy and peaceful feeling
62. “And the word ‘green’ today can keep food prices going up.” This sentence suggests that consumers today are ________.
A.starting to notice the importance of new food
B.enjoying the beauty of nature more than before
C.beginning to like green vegetables
D.paying more attention to their healthy
63.It can be inferred from the passage that V8 is a kind of ________.
A.vegetable dish  B.healthy juice    C.iced drink D.red vegetable

For many young people, the dream of a lifetime is to travel the world, explore different cultures and landscapes, taste new foods and flavors, and listen to the distinctive sounds of international music and languages.
Unfortunately, few young people have the money or freedom to make this dream come true. But if you can't go out into the world, surely second best is to let the world come to you. And, this year's Shanghai World Expo is exactly where that's happening.
From May 1 to October 31, there will be 194 countries and 50 international organizations on display at the 5-square-km Expo site. Seventy million domestic and international visitors are expected to visit it by the end of October. So, if you can go, you'll be surrounded by people with a wide range of backgrounds, nations, and cultures.
The Expo's theme is "Better City, Better Life". The United Nations estimates that, this year, 55 of the world's people will live in urban settings. This poses a dilemma (困境) for the world's cities: How can they accommodate such a large number of people in a sustainable (可持續(xù)的) way? Can they remain places of natural beauty and cultural importance?
Well, that's the challenge the 2010 Expo participants are confronting in a variety of ways. Japan will show off an "eco-breathing" structure to power its building with natural energy like sunlight, rainwater and wind. Germany's pavilion is named "Balancity", which is described as a "balance between innovation (創(chuàng)新) and nature, society and its individuals, work and recreation" (娛樂)
The first themed Expo was held in 1933, and since that time World Expos have featured a participatory and interactive style. The Shanghai Expo is no exception. Young people will have the opportunity to take part in forums to discuss themes like new technology, green energy and conservation.
A trip to the Expo is guaranteed to be much less expensive than a trip around the world. Still, the costs can add up. However, young people can save money by purchasing group or student tickets, which may be available at reduced rates. Many of the participating pavilions offer free samples and treats for the visitors. In addition to handing out free chocolates, the Belgian pavilion will give away a free diamond each week to a visitor who can answer questions related to Belgium.
If you're planning to head to the Shanghai Expo between May and October, don't forget to bring a camera, a notebook, and an open mind (and comfortable shoes). For nearly six months, representatives of the world are coming together to share their best and latest ideas for the future. It's sure to be a memorable experience.

C.
“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated (脫水)at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
63. We need _____for a healthy diet.
A. fibre        B. food       C. water    D. Water and different foods
64. From the text, we know water can carry_________.
A.energy and fibre in our bodies     
B.fruit, vegetables and fish in our bodies
C.sugar and fat out of our bodies
D.poisons and waste out of our bodies
65. Lack of water caused people to put on weight too much because_______.
A.they think they are hungry and eat too much
B.they think they are thirsty and eat less
C.water has no calories
D.it makes them hungry
66. Which of the following isn’t mentioned in the passage?
A.Fruit provides us with energy and fibre.
B.Some healthy problems start because of a lack of water.
C.Drinking more water may stop people from overeating.
D.The amount of water a person should drink in a day.

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入,攝入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增強) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units(IU)a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
61. According to the passage, people are advised to take more Vitamin D, because__.
A. it is nutritious             B. it can‘t harm people’s health
C. it can lower cancer risk      D. it is not taken enough every day
62. Which of the following can not help people get more Vitamin D?
A. Have some sunshine        B. Have more meat
C. Have more fortified cheese   D. Have a vitamin supplement
63.Who can Garland probably be?
A. A health researcher        B. A doctor   
C. A scientist               D. A public health official
64.Which of the following food can lower people‘s chance of getting cancer?
A. Milk                    B. Fortified orange juice
C. Fortified yogurt           D. All of the above
65.People from which area should take more Vitamin D according to the passage?
A. Asian people               B. African people 
C. American people            D. European people

The beet (甜菜) is a tasty root vegetable that does not require much work to grow. People think of beets as being always dark red,but they can also be pink,yellow or white. Beets are high in nutrients,and both the root and the tops can be eaten. The leaves make good salads when the plants are young,and the greens can be cooked when the plants are older. Beets grow best in full sun and in loose soil that is not too wet.
Remove stones from the soil while preparing the ground,and test it before adding fertilizer Beet seeds can be planted as soon as the soil can be worked at the start of the growing season. Planting them every two or three weeks will provide a continuous harvest into the fall. A beet seed is a fruit containing several seeds. Overcrowding the plants will mean that the roots cannot spread out and grow,so thin the beets by removing the smaller ones and using them as greens.
A specialist named Cindy Haynes says little or no fertilizer is needed in rich soils. Once the seeds are planted,however,she suggests covering the soil to protect it from the rain and during dry periods. She also suggests putting a fence around the plants to keep away rabbits and deer. She says the only work beets need once they have been thinned is weeding and, when the weather is dry,a weekly watering. For best results,beets should be picked when the roots are two and one-half centimeters around. Larger beets can be tough,and have to be cooked for a long time. Beets can be eaten in many ways.
60.What is the second paragraph mainly about?
A. How to test the soil.           B. How to plant beets
C. When to harvest beets.          D. When to plant beets.
61.Smaller beets are often removed in order to       .
A. give other beets space to grow    B. add more fertilizer to the soil
C. plant new seeds                D. use the green,young leaves in salads
62.What may the next part of the last paragraph be about?
A. When to pick beets.             B. How to eat beets.
C. The uses of beets.              D. The taste of larger beets.

D        
"In only six days I lost seven pounds of weight. "
"Two full inches in the first three days!"
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration )can require proof (證明) under the Food, Drug, and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health. FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律訴訟),and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
71. It can be inferred that the ads mentioned in the text are        .
A. objective    B. costly    C. unreliable    D. illegal
72. Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.
D. The promoters usually just care about profits.
73. FDA can ask for the proof of safety and effectiveness of a product        .
A. if it is a drug      
B. if it is a device
C. if its consumers make complaints
D. if its distributors challenge FDA's authority
74. The Relaxacisor is mentioned as        .
A. a product which was designed to produce electricity
B. a product whose distributor was involved in a legal case
C. a successful advertisement of a beauty product
D. an example of a quality beauty product
75. The author intends to        .
A. make consumers aware of the promoters' false promises

E
Some recent reports on the death penalty have brought some interesting responses from
readers all over the country. Although I really don’t like to make fun of people who oppose the
death penalty because they are so sincere, I wish they would come up with some new arguments to
replace the worn-out ones.
For example, many said something like this : “Wouldn’t it be better to keep the killers alive so
psychiatrists(精神科醫(yī)生)can study them in order to find out what makes them the way they are?”
It takes the average psychiatrist about five years to figure why a guy wants to stop for two drinks after work and won’t quit smoking. So how long do you think it will take him to determine why somebody with an IQ of 92 decided to murder the little old lady who lives next door? Besides, we have a huge number of killers in our prisons—more than enough to keep all the nation’s psychiatrists busy for the next 20 years.
Another standard is: “The purpose of the law should be to protect society, not to give cruel punishment, such as the death penalty.”
In that case ,we should tear down all the prisons and let all the criminals go because most people would consider a long period in prison to be cruel punishment--especially those who are locked up. Even 30 days in the Cook County Prison is no picnic.
And: “What gives society the right to take a life if an individual can’t?” The individuals who make up society give it that right. Societies perform many functions that individuals can’t. We can’t carry guns and shoot people, but we give that right to police.
Words can not explain the suffering the families of murder victim are left to live with. The families suffer a terrible loss, and they live with terrible memories. The knowledge that the killers are alive and will probably remain alive and cared for you by society is extremely painful. Probably, people who oppose the death penalty should try explaining to these people how cruel it is to kill someone.
72.What’s the writer’s attitude towards death penalty?
A.Death penalty is a must.
B.Death penalty doesn’t solve all the problems.
C.Death penalty should be practiced more carefully.
D.Death penalty should only be used on murderers.
73.How many arguments against death penalty are discussed in the passage?
A.Two  B.Three       C.Four  D.Five
74.What does the last sentence of the text suggest?
A.It’s cruel to use death penalty to kill someone.
B.Murder victims need more comfort from the society.
C.Opponents of death penalty should offer explanations.
D.Murderers should be put to death as the punishment.
75.The author develops the passage by         .
A.providing typical examples of death penalty
B.following the natural time order
C.presenting and analyzing ideas
D.comparing opinions from different fields
