Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.

In fact, medical experts warn that taking too many of some vitamins can be harmful. For

example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.

Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.

Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.

In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.

5. Vitamin supplements are popular with people because ________. 

A. people mistakenly think that they are good for their health

B. they contain more vitamins than the foods people eat

C. food does not provide enough vitamins people need

D. people fear that a lack of vitamins will lead to disease

6. From the passage, we can learn that medical experts advise people _________.

A. never to take any vitamin supplements  

B. to depend only on food for their vitamins

C. not to take any vitamins together with medicines

D. to consult doctors before taking vitamin supplements

7. For people who lack Vitamin B-twelve, they can eat more from _______.

A. sweet potatoes   B. pork products   C. green leafy vegetables   D. eggs

8. What would be the best title of the passage?

A. Getting enough vitamins through a balanced diet.

B. Vitamin supplements do harm to our health.

C. Vitamins are important to our health.

D. Lacking vitamins can cause many diseases.

There is an English saying, “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health. Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes

people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.

As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A. Laughter is good for health.         

B. Laughter can make you become old quickly.

C. Laughter helps to reduce pain.    

D. Laughter, just like physical exercise, is good for our body.

10. The underlined word “diminishes” in the third paragraph means “          ”.  

A. delays         B. prevents         C. increases        D. reduces

11. Why do doctors hold laughter clinics? 

A. Because they want to earn more money.     

B. Because they think they will help the patients recover from illnesses.

C. Because they want to improve their patients’ health.

D. Because they want their patients to laugh more.            

12. What would be the best title for this passage?  

A. Both laughter and physical exercise are good for health.

B. Laughter clinics can help patients improve their condition.

C. Laughter can reduce the effect of pain.         

D. Laughter is the best medicine.

In Canada you can find dogs, cats, horses, etc．in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to animal hospitals to give them injections（注射）so that they won’t carry disease.
