Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain Cases, harmful.
In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pennsylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins (毒素) better, improves skin, and helps reduce weight.
Dr Goldfarb and Dr Negoianu say that they found little proof to support the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they found little proof of harm in drinking 8 glasses of water every day.
It is widely believed that in some cases — such as athletes, people who live in hot, dry environments, and those with certain medical conditions — drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines. com reports.
The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, “but the difference in the number of headaches was so small between the two groups as to be considered unimportant.”
The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each day.
The website medheadlines. com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur.
1. What’s the key message delivered in the passage?
A. Drinking too much water might bring harm.
B. Whether to drink enough water makes no difference.
C. Drinking too much water may cause headaches.
D. Average, healthy people should drink more water.
2. We can learn from the passage that 8 glasses of water every day ________.
A. proves good for the body B. has scientific proof of harm
C. is sure to reduce headaches D. is generally considered necessary
3. Who may agree that drinking lots of water helps to lose weight?

A. the website medheadlines. com is developed by an Indian doctor

Things have changed much recently and now raising pets has become a popular pastime , resulting in a successful pet care industry .
Pet food is sold in almost all supermarkets and many special stores for pet needs have been set up .
Animal hospitals provide various medical services for sick dogs and cats , and pet exchange fairs are held regularly .
At the China International Pet Show which took place recently in Beijing , more than 100 factories from across the country exhibited their products . Thousands of dealers and pet owners went to the show.
“People’s swollen pockets make it possible for many to raise pets , a hobby that used to be enjoyed only by the wealthy ,” said Wang Wei , who works with the National Kennel Association of China .
Wang Yuyan , vice president of the Small Animals Protection Association , agreed , “ In many films and novels , having a pet is used as a symbol of wealth . That’s not a complete picture . ” Wang added that pets are friends in a real sense of the word , not just playthings . “ Anyone with a loving nature can raise pets . ”
Still the high cost of keeping a pet is something many people have to think about .
“I like dogs and cats , but I have neither time nor money to raise them , ”said Li Jun , in her 40’s , a civil servant from Beijing .
The cost of raising a dog is high in Beijing , where registration (登记) is a must for all dogs and costs 5,000 yuan for each animal . In addition , pet owners must pay for regular injection of vaccines (疫苗). Most of all , dog food is quite expensive .
Unlike his mother , Li Jun’s 10-year-old son, Li Qiyu, dreams of the day he will have his own pet . “I hope I can have a dog in my house , ” he said .

Will it matter if you don’t take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains, if a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to what many people believe, if you don’t eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
77. The results of the test show that ______
A. breakfast has great effect on work and studies.
B. breakfast has much to do with people’s health.
C. a person will work better if he has simple breakfast
D. breakfast only affects those who work with their brains.
78. The passage mentions that many people believe that if you don’t eat breakfast, you will____.
A. not lose weight B. be healthier
C. gain weight D. lose weight
79. We can infer from the passage that _____
A. one can work better without breakfast.
B. morning diet will do good to your health.
C. reducing lunch and supper will help lose weight.
D. breakfast is more important than lunch and supper.
80. What is the best title for this passage?
A. Good Breakfast B. Why Eating Breakfast?
C. No eating, No gaining D. What is breakfast |
The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.
A multitude of factors, both inherited and environmental, influence the development of health related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Grapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.
68．The concept of personal choice concerning health is important because ____.
A．personal health choice helps cure most illness
B．it helps raise the level of our medical knowledge
C．it is essential to personal freedom in American society
D．wrong decisions could lead to poor health
69．To “live a completely sedentary life style”(L7,Para.1)in the passage means____.
A．to “live an inactive life” B．to “live a decent life”
C．to “live a life with complete freedom” D．to “live a life of vice”
70．Sound personal health choice is often difficult to make because ____.
A．current medical knowledge is still insufficient
B．there are many factors influencing our decisions
C．few people are willing to trade the quality of life for the quantity of life
D．people are usually influenced by the behavior of their friends

第一节：阅读理解（共15小题，每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
What is a creepy crawly?
A few years ago, I was on a bicycle trip when I got off my bike for a rest. I sat down on the grass. A few seconds later, I was covered in ants. They were swarming all over me so I got up and brushed them off. It was a strange experience but I soon forgot about it.
A couple of years later, I was living in Jordan. I had just moved into a modern flat and was unpacking plates when I saw something move out of the corner of my eye. I looked over at the kitchen drawer and there was a cockroach crawling out of it. I screamed. Then I grabbed a can of insecticide and sprayed it on the cockroach. He ran under the nearby bathroom door. It took me three days before I found the courage to open the bathroom door to see if he was still alive. He wasn’t.
Why did I react so violently to one lone insect when a closer encounter with hundreds of ants hardly affected me? The answer is easy: because cockroaches are creepy crawlies and ants aren’t. Creepy crawlies are those little bugs which provoke feelings such as uneasiness, anxiety or dislike – they make your skin crawl.
Did you know that some people feel such a fear of bugs that it becomes a phobia? Psychologists have offered many explanations. Some say we associate them with dirt and disease. Or that these are life forms that are so alien to us, that we find them repulsive(令人厌恶的) for their dissimilarity.
Insects, however, don’t follow our rules – they just do what they want and invade our space. Unfortunately, although insects and bugs have been a successful animal species up to now, many of them, like many other species nowadays, are under threat of extinction. Entomologists warn that this could upset entire ecosystems and lead to all kinds of disastrous consequences.
So my plea to you is: the next time you feel the urge to stamp on, splatter or spray a creepy crawly, give a thought to the planet and stop.
