Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.
But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.
Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.The first paragraph is mainly about .

More American people take their troubles with them on holiday, according to a new survey. Although 40 percent said that the main reason for going away is to escape pressure (压力) from work, almost all said they worry more than they do at home. Only four in every 100 said that they are happy and free of care.
The most common worry is burglary ( 入室盗窃), with four out of 10 worrying about their homes being broken into while they’re abroad. More than a quarter fear they will feel crazy with some other noisy and rough holiday-makers and 22 percent worry they may be attacked or their possessions will be missing. One in five think the car may break down; and the same number worry about the chances of bad weather.
The survey also showed that the stay-at-home Americans are no more. Three out of every five want to have a holiday abroad, a great increase from the figures only three years ago. The hotel holiday is still a winner, with about one third of all Americana preferring to go on a self-catering ( 自助 ) holiday.

Shopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand （品牌） of product on the shelf.
Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged （包装）in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver.
When some kind of pain killer was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm.
The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.
It is believed that the better-known companies spend, on average, 70 per cent of the total cost of the product itself on packaging!
The most successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote （推销） their goods, came to the conclusion: “Any fool can make soap, but it takes a genius （天才） to sell it.”

Since many of you are planning to study at a college or university in this country, you may be curious to know what you usually do in a typical week, how you can get along with your fellow students, and so on. These are the questions I want to discuss with you today.
First, let’s talk about what your weekly schedule will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lectures. Lectures are usually in very large rooms because some courses such as introduction to sociology or economics often have as many as two or three hundred students, especially at large universities. In lectures, it’s very important for you to take notes on what the professor says because the information a lecture is often different from the information in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn’t enough to just read your textbooks; you have to attend lectures as well. In a typical week you will also have a couple of hours of discussion for every class you take. The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students, called teaching assistants, usually direct discussion sections.
If your major is chemistry, or physics, or another science, you’ll also have to spend several hours a week in the lab, or laboratory, doing experiments. This means that science majors spend more time in the classroom than non science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do.
59. The main purpose of this text is .
A. to help the students to learn about university life
B. to persuade the students to attend lectures
C. to encourage the students to take part in discussions
D. to advise the students to choose proper majors
60. We can learn from the passage that university professors .
A. spend about 5 hours on lectures each week
B. must join the students in the discussion sections
C. prefer to use textbooks in their lectures
D. require the students to read beyond the textbooks
61. A discussion section does NOT include .
A. working under the guidance of university professors
B. talking over what the students have read about the courses
C. discussing the problems related to the students’ homework
D. raising questions about what a professor has said in a lecture
62. According to the author, science majors .
A. have to work harder than non science majors
B. spend less time on their studies than non science majors
C. consider experiments more important than discussions
D. read and write less than non science majors
Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about drinking is the key to critical（判断性的）thinking. When you think critically, you take control of your thinking processes（过程）. Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.
The word “critical” here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen-beyond the pictures on TV, the untrue reports in the newspapers, and the faulty reasoning.
Critical thinking is an attitude as much as an activity. If you are curious about life and desire to dig deeper into it, you are a critical thinker. If you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker.
Activities of the mind and higher-order reasoning are processes of deep and careful consideration. They take time, and do not go hand in hand with the fast speed in today’s world: fast foods, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure of intelligence（智力）, you may learn something new from a story about Albert Einstein. The first time Banesh Hoffman, a scientist, was to discuss his work with Albert Einstein. Hoffman was too nervous to speak. But Einstein immediately put Hoffman at ease by saying, “Please go slowly. I don’t understand things quickly.”
72．Critical thinking is important to us because if we do not think critically, _______.
A．it will be hard for us to think naturally and fast
B．we might be controlled by other people’s ideas
C．we will follow the ideas of others naturally
D．we might be footed by other people’s ideas
73．If you are a critical thinker, you will ________.
A．think deeply about different ideas B．trust the reports in the newspapers
C．take one view against another view D．criticize other people for their mistakes
74．In the last paragraph, “something new” suggests that ________.
A．the smarter you are, the faster you do things
B．the faster you do things, the smarter you become
C．speed can improve intelligence
D．intelligence is not decided by speed
75．What would be the best title for the passage?
A．Thinking and Critical Thinking. B．Understanding Critical Thinking.
C．Thinking Is Natural and Human. D．Thinking Fast Means Intelligence.
There are thousands of products of all colors and shapes in a supermarket, making you believe that they are worth a try. How? Packaging （包装）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（消费者）, 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（反应）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．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
