If you have to miss a meal a day, which meal will cause you fewest health problems if you don"t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast. However, many experts in the field of health consider breakfast ( the meal which "break" you "fast" ) to be the most important t meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (营养) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we ignore the importance of breakfast? One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12 to 83. The results showed that if a person eats an adequate breakfast, he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person"s work involves mental(脑力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate (集中)on their lessons for a longer period of time than if their breakfast is inadequate. The study also showed that contrary to what people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals. |

A. a good breakfast breaks you down fast B. you"ll lose weight quickly if you skip breakfast C. breakfast provides what a person needs to work D. after a long night, you"ll feel very hungry |

A.school-children will be quick and attentive all day if they eat breakfast B.a proper breakfast will make mental workers more efficient C.fruit, eggs, bread and milk are the best breakfast for mental workers D.school-children who have breakfast are much brighter than those who don"t |

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can"t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain. Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain. Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys" blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys" brains. When the brain"s temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them. |
1. The biggest difficulty in operating on the damaged brain is that _______. |
A. the time is too short for doctors B. the patients are often too nervous C. the damage is extremely hard to fix D. the blood-cooling machine might break down |
2. The brain operation was made possible mainly by _______. |
A. taking the blood out of the brain B. trying the operation on monkeys first C. having the blood go through a machine D. lowering the brain"s temperature |
3. With Dr. White"s new idea, the operation on the damaged brain _______. |
A. can last as long as 30 minutes B. can keep the brain"s blood warm C. can keep the patient"s brain healthy D. can help monkeys do different jobs |
4. What is the right order of the steps in the operation? a. send the cooled blood back to the brain b. stop the blood to the brain c. have the blood cooled down d. operate on the brain |
A. a, b, c, d B. c, a, b, d C. c, b, d, a D. b, c, d, |

Putting in water fountains (饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal Pediatrics. The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutritionist(营养学家) at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage consumption(饮料消费量). At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains. At the beginning of the study, there were no big differences in the number of overweight children in the different groups. But by the end of the school year, children in the schools with water fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged. Children in the schools with fountains increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said. The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite (食欲). |

A. may cover the subject of the health of children B. mainly deals with the water drinking problem C. is mainly about the mental health of kids D. must be a journal entitled by a school |

1970 was World Conservation(自然保护)Year. The United Nations wanted everyone to know that the world is in danger. They hoped that people would act quickly in order to conserve nature(大 自然). Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man. It is said that there are tens of thousands of kinds of animals in the world, but now many have died out(绝种). We are changing the earth, the air and water, and everything that grows and lives. We can"t live without these things. If we continue like this, we shall destroy ourselves. What will happen in the future?Perhaps it is more important to ask"What must we do now?"The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conservation through a record called"No one"s going to change our world."It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals. |
1. "No one"s going to change our world"was___________ . |
A. an important book published in 1970 B. an idea that nobody would accept(接受) C. a record calling on people to conserve nature D. a newspaper report in 1970 |
2. What"s the most important thing for us to do to save our world? |
A. We should know what will happen in the future. B. We should plant more trees and flowers. C. We should clean the banks of our rivers. D. We must do what we must do to save our world. |
3. What"s the main idea of the passage? |
A. 1970 was World Conservation Year. B. The United Nations wanted everyone to know that the world is in danger. C. Conservation is necessary. D. Young people are helping to save our world. |

Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment (营养).The old saying "An apple a day keeps the doctor away "is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form, believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn"t need or use extra vitamins, so why waste money on them? In the modern western world, many people are too busy to bother about eating properly. They throw anything into their stomachs, eating hurriedly and carelessly.
