The scientists say that the human body has changed very little since human first appeared on earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes（中风） are examples of such diseases.
Scientists noted that early stone-age people used very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and life today.
Stone-age people hunted wild animals for their meat, which had much less fat than farm animals. They also ate a lot of fresh wild vegetables, and fruits. They did not use milk and other dairy products, and they made very little use of grains. But today, we eat a large amount of dairy products and grain foods. We eat six times more salt than stone-age people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
People today probably do not want to live as people thousands of years ago did, but scientists say that we would be much healthier if we ate as those ancient people did, cutting the amount of fatty, salty and sweet foods.

| A．more foods as humans living 10,000 years ago did |
| B．as humans living 10,000 years ago ate |
| C．more kinds of food eaten by people living over 10,000 years ago |
| D．more of the same kinds of foods eaten by people over 10,000 years ago |
| A．the human body has changed compared with human first appearing on earth |
| B．the way we live has changed a little |
| C．our body can’t deal with the changes in life style |
| D．the way we live today are improper for the human body |
| A．Ancient people did a great deal of physical exercise. |
| B．People today have a lot of alcohol. |
| C．People today have more tobacco. |
| D．Food is quite different between life today and life in ancient times. |

Mothers, doctors and nurse alike have no idea of where a baby"s blood sugar level lies. All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.
It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night. I"ve never heard anything so ridiculous. Baby feeding shouldn"t follow a timetable set by the mum. What is important is feeding a baby in the best way, though it may cause some inconvenience in the first few weeks.
Well, at last we have copper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding . The research finds out that babies who are fed on demand do better at school at age 5, 7 , 11 and 14, than babies fed according to the clock. By the age of 8, their IQ（智商）scores are four to five percent higher than babies fed by a rigid timetable. This research comes from Oxford and Essex University using a sample（样本）of 10,419 children born in the early 1990s,taking account of parental education, family income, a child"s sex and age, the mother"s health and feeling style. These results don"t surprise me. Feeling according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels.
I hope this research will put an end to advocating strictly timed baby feeling practices.
小题1:What does the author think about Dr King?
| A．He is strict |
| B．He is unkind |
| C．He has the wrong idea. |
| D．He sets a timetable for mothers |
| A．basic | B．reliable | C．surprising | D．interesting |
| A．The baby will sleep well. |
| B．The baby will have its brain harmed. |
| C．The baby will have a low blood sugar level. |
| D．The baby will grow to be wiser by the age of 8. |
| A．in the night |
| B．every four hours |
| C．whenever it wants food |
| D．according to its blood sugar level |
Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack (缺乏) of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth.
Drinking carrot juice is thought to be extremely helpful to the liver (肝脏), because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time.
Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.
How can you make carrot juice? Wash some carrots well in cold water. Scrape (刮) them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin.
小题1:Lack of vitamin A can lead to _____.
| A．skin dryness | B．broken bones |
| C．complete blindness | D．liver cancer |
| A．is popular because it is a magic cure for many diseases |
| B．does a lot of good to the teeth and other parts of the body |
| C．can wash away the waste from the body |
| D．may be harmful to the body if it’s drunk too much |
| A．drinking carrot juice helps to protect your eyesight |
| B．driving cars at night may lead to night blindness |
| C．walking from a bright room into a dark room may lead to night blindness |
| D．you will find it easy to get used to the change of light if you lack vitamin A |
| A．Tips on How to Make Carrot Juice |
| B．The Way to Keep Good Health |
| C．The Great Benefits of Carrot Juice |
| D．A Healthy Diet for Patients |
Now I don"t expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I"m glad to cook traditional meals of meat and potatoes for them. I really can"t be too upset with the kids because most adults aren"t careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can"t eat hot dogs, with all those preservatives（防腐剂）, and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don"t want the world to change because of me, but I think people should realize that there are alternatives(选择) to eating meat. They always tell me that I probably don"t get my essential(必要的) proteins. I feel better than ever and I"m sure that it"s because I"m a vegetarian(素食主义者). I would really like to see more television advertisements which show the benefits of good, healthy, natural food.
小题1:According to the passage, it seems that ______.
| A．canned food is the only one that the kids enjoy most. |
| B．the children like to have fried chicken only. |
| C．the kids prefer to have cold drinks, not junk food |
| D．the children like nothing better than junk food: cookies and chips |
| A．Television influences children’s food choice |
| B．The author is not single and he eats meats |
| C．Though the author is a vegetarian, he feels very healthy |
| D．It is certain that beans and spinach are not junk food |
| A．why he goes to the party | B．whether he gets enough proteins |
| C．whether he allows his children to eat meat | D．whether he is healthy and strong |
Even people who spent just a few hours a week on the Internet experienced more depression(沮丧) and loneliness than those who used Internet less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling.
Researchers are puzzled by the results, which were completely the opposite to their experiences. They expected that the Net would prove socially healthier than television, since the Net allows users to choose the information and to communicate with others.
The fact that Internet use reduces time available for family and friends may explain the drop in well-being, researchers supposed. Faceless, bodiless “virtual” communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that knowing the wider world via the Net makes users less satisfied with their lives.
“But it’s important to remember this is not about the technology; it’s about how it is used,” says psychologist Christine Riley of Intel, one of the study founders. “It really points to the need for considering social factors in terms of how you design applications(应用) and services for technology.”
小题1:The best title of the passage probably is .
| A．Internet May Cause Depression |
B．The Danger of Internet  |
| C．Communication with Others by Internet |
| D．Puzzled by the Results |
| A．People could choose their information through Internet. |
| B．They had expected the opposite results. |
| C．People can communicate with others. |
| D．They had thought Internet was much healthier. |
| A．Net users found their living conditions bad. |
| B．Net users already had mental problems. |
| C．Deep relationships were formed through Internet. |
| D．Net users had less time to communicate with other people. |
| A．social factors must be considered while using technology |
| B．technology was to blame for depression |
| C．the problem doesn’t lie in technology |
| D．applications and services for technology must be designed |
People have strange ideas about food. For example, the tomato is a kind of very delicious vegetable. It is one of useful plants that can be prepared in many ways. It has rich nutrition and vitamin in it. But in the 18th century, Americans never ate tomatoes. They grew them in their gardens because tomato plants are so pretty. But they thought the vegetable was poisonous (有毒的). They called tomatoes “poison apples.”
President Thomas Jefferson, however, knew that tomatoes were good to eat. He was a learned man. He had been to Paris, where he learned to love the taste of tomatoes. He grew many kinds of tomatoes in his garden. The President taught his cook a way for a cream of tomato soup. This beautiful pink soup was served at the President’s party. The guests thought the soup tasted really good. They never thought their president would serve his honored guests poison apples. Jefferson never spoke to his honored (忠实的) guests about the fact.
