It's time you started eating sensibly. Experts at the first Chinese Students Nutrition and Health Festival in Kunming last week listed eight bad eating habits.

    ●Watching television while having meals or snacks.

    Doing this means you don't pay attention to your food, forget how full you are, and so overeat. It can also cause digestion (消化) diseases. One way to avoid this is only to eat in certain areas of your home.

    ● Replacing meals with snacks.

    Many students think that eating small snacks can help them diet. But it often results in overeating and health problems related to a lack of vegetables, carbohydrates (碳水化合物),proteins and vitamins. Snacking only works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt.

●Having drinks rather than water.

Fizzy (有气泡的) drinks and fruit juice are usually high in calories and sugar, which can

cause weight problems. Water is important in making your brain cells and every organ in your body work properly. For your body to burn fat, it needs at least eight glasses of pure water a day. Liquids like soda and coffee actually take water away from your body.

●Refusing to drink milk.

Milk is the best natural food—it provides you with protein, which makes your bones strong and teeth healthy.

    ● Choosing meat and certain vegetables over others.

    Different foods provide different kinds of nutrition. If you don't have a balanced diet, this can result in malnutrition (营养失调) and a weaker body.

●Eating in front of the computer and staying there after meals.

Take a walk after eating and it helps your stomach digest the meal.

●Buying from roadside snack bars.

If you shop at these places, be careful—many are not clean enough.

    ● Eating throat tablets as if they were sweets.

    If you eat throat tablets when you have no throat disease, they may affect the bacteria in your mouth and cause real throat problems.

______ can possibly cause digestion problem.

A. Eating while sitting in front of TV or computer

B. Eating throat tablets as if they were sweets.

C. Choosing certain kinds of food over others.

D. Buying from roadside snack bars.

Why can't soft drinks be drunk in place of water when you feel thirsty?

A. They help brain cells work properly.      B. They make your body sick.

C. They take water away from your body.    D. They supply energy for your body.

Which of the following is NOT the habit that will possibly result in a lack of nutrition?

A. Often eating small snacks.            B. Never drinking milk.

C. Always eating the same kinds of food.   D. Staying in front of a computer after the meal.

Bad teeth can be painful — and worse. They can even be deadly. Infections (感染）of the gums (牙龈）and the teeth can cause bacteria (细菌）to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk. For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿 保健）he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物）to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (法琅质)， the hard surface on teeth, to help prevent holes from forming.
31.According to the passage, bad teeth can be ____________.
A.painful  B. deadly  C.preventive  D.incurable

33. What's the main idea of paragraph 4 and 5?
A. How to develop babies' teeth.           B. Why to protect babies' teeth
C. How to keep babies' teeth clean         D. Why to keep babies' teeth clean
34. The passage tells us that _______.
A. Enamel is most widely used to protect teeth in the world
B. Bad teeth may affect the health of adults and the young
C. Breast milk can cure babies' bad teeth
D. Babies' teeth should be brushed once per day
35.Which of the following can be used as the title of the passage?
A. Concerns for Healthy Teeth of the Young  B. Importance of Healthy Teeth of All

C.O.P.D(慢性障碍性肺病) blocks air flow through the lungs. It makes breathing difficult. The leading cause of C.O.P.D. is cigarette smoking. Experts at the National Institutes of Health in the United States say there is no cure to the damage to the lungs.

Dawn Demeo is an assistant professor at Harvard Medical School in Boston, Massachusetts. She said, “By 2020, C.O.P.D. may be the third leading cause of death across the world.”

C.O.P.D. is a new name for emphysema（肺气肿） and chronic bronchitis（慢性支气管炎）. These are the two most common forms of the disease. Many people with C.O.P.D. have both of them. And Doctor Demeo says more women than men now die from the disease.

She is the lead author of a study by a team from Harvard’s Brigham and Women’s Hospital and the University of Bergen in Norway. The new study adds to findings that women may be more at risk than men from the damaging effects of smoking.

The team examined results from a Norwegian study of 954 people with C.O.P.D. Inga-Cecilie Soerheim co-wrote the team’s findings. Doctor Soerheim says they show that women suffered the same level of C.O.P.D.as men. But the female smokers were younger and had smoked a lot less.

The team also looked at two groups among the people in the study. These were people under the age of 60 and those who had smoked for less than 20 years. In both cases, women had more serious C.O.P.D. and a greater loss of lung function (功能）than men.

1.Which of the following statements about C.O.P.D is NOT true ______.

A. Cigarette smoking is likely to cause C.O.P.D.

B. C.O.P.D. makes it hard for a person to breathe

C. C.O.P.D will be one of the most life-threatening diseases.

D. Many people with C.O.P.D. have either emphysema or chronic bronchitis.

2.It can be known from the study that_____.

A. female smokers die faster than male ones.  

B. women are more likely to suffer from the damaging effects of smoking than men.

C. women who suffer the same level of C.O.P.D as men were older and weaker.

D. in the group of people under the age of 60, men suffered more from C.O.P.D than women.

3.Which of the following can be the best title for the passage?

A .Smoking Kills

B. Smoking Triggers Diseases

C. The Leading Causes of C.O.P.D.

D. Women Suffers More from C.O.P.D. than Men  

4.In which part of a newspaper would you most probably read this passage?

When you run, you put force that is equal to three times your body weight on your feet. The human foot contains twenty muscles. This means that there is a lot that can go wrong when you run.

Most sports have some kind of running or jumping So experts at many shoe companies work hard to design good sport shoes. First, a designer enters a plan for a shoe into a computer .Engineers then improve the design. A second computer designs a model for the shoe. Then a few pairs are made. Next, the shoe is tested.

Different kinds of sports shoes are made for different uses. Some are made to help marathon(马拉松) runners save energy during a race. Some are made for the stop-and-go kind of running tennis players. But all sport shoes have one thing in common: they are designed to help people’s feet comfortable during sports. Today, nearly every sport has its own special shoe designed for just the kind of running that sport needs.

1.The first in making a new shoe is to ________.

A．make a computer                       B．put a design plan into a computer

C．design a shoe model                     D．test several pairs

2.Why are good sport shoes welcome to people?

A．Because they are comfortable to wear.

An important scientific report announced “irrefutable（不能反驳的） proof” that climate change is happening and it’s all our fault. How long has it been before people are against the global warming idea? But here’s a funny thing. Last year there was a very bad hurricane season in the Caribbean when, among other disasters, New Orleans was all but wiped off the map. We were wisely informed by the experts at the time that this was owing to global warming.

I remember watching a BBC science programme and hearing a learned professor with a beard tell us, “The increased frequency and strength of hurricanes is what we shall have to learn to expect given global warming.”

This year there have been far fewer hurricanes and those there have been were relatively mild. Why？Global warming again of course. Professor Bjorn Lomborg, author of The Skeptical Environmentalist, writes, “In the constant media reports of possible greenhouse related disasters, almost any event is now linked to climate change.” He adds, “We should not spend vast amounts of money to cut a tiny slice of the global temperature increase when this leads to a poor use of resources and when we could probably use these funds far more effectively in the developing world.” For saying this, Lomborg has had death threats.

Other scientists who do not toe the global warming-is-happening-and-it’s-all-our-fault line have received the same. There are plenty of people who count against global warming. A world of senior climatologists and meteorologists wrote to the Times last year to complain that they couldn’t get their research findings published — because they disagreed to it. We have had a warm autumn. The experts,  fanatics（狂热者） all of them, put it down to global warming. If we have an extra cold winter, they will tell us it’s a result of global warming. If my big toe feels cold or hurts badly, it will be owing to global warming.

52. The purpose of this passage may be to ____.

A. support the idea of global warming  

B. organize a debate about global warming

C. speak out against the global warming idea

D. encourage people to use money effectively

53. What happened to New Orleans last year?

A. It was badly destroyed.                          B. It disappeared in the world.

C. It witnessed global warming.               D. It experienced several disasters.

54. From the passage, we can infer that ____.

A. people are taking too many efforts to stop global warming

B. people have realized the side effect of development

C. a different idea sometimes may cost one his life

D. the majority usually stand for the correct opinion

55. The main idea of the last paragraph may be ____.

A. global warming may lead to toe’s catching cold in a sense

B. the Times refuses to publish articles on global warming

C. a warming autumn is not related to global warming at all

D. it is certainly incorrect to owe everything to global warming
