Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.

Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.

Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.

Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

1.According to the passage,_________.

2.In order to keep good health, ___________ .

Gene therapy (基因治疗) is a revolutionary new technique for treating people with health problems. Up until very recently, the most commonly available methods for treating patients were either through drugs or operations. Gene therapy provides a third option for treatment by transforming or replacing cells with new genetic materials and instructions. Scientists can be very precise in the kinds of changes they make in patients.

Gene therapy works by using a delivery system, such as a virus, to enter a patient's body. Once inside the body, the virus combines with a host cell and delivers the new DNA. The proteins then begin to repair the affected cells. New techniques have focused on removing cells from the patients and transforming them outside the body before reintroducing them to the patients.

The two types of gene therapy are called somatic and germline. Somatic therapy refers to changing or replacing a body cell. In this case, the treatment is restricted to the patient only. This will not affect the patient's future children because the patient's germ (生殖) cells are unaffected. In germline therapy, the patient germ cells are treated, which may affect the patient's future generation.This is highly controversial (有争议的) because it is not clear exactly how this might affect them and further generations. For this reason, many countries have passed laws that prohibit this kind of treatment.

Despite the promise of gene therapy, there are still many barriers that need to be overcome before it comes into widespread use. One of the issues is that the use of viruses to deliver DNA may actually cause unexpected problems in patients if the virus grows and attacks the body. Another problem is the nature of many diseases is very complex and spread throughout multiple genes. The use of gene therapy to change a single gene in the body would probably not be sufficient as a cure. Finally, the costs of gene therapy are high. Some gene therapy procedures may cost over$1 million to undertake and require specialized doctors and equipment.

1.What does the underlined word ''them'' in paragraph 2 refer to?

A.Techniques. B.Cells. C.Patients. D.Proteins.

2.What can we learn about gene therapy?

A.Gene therapy has been put into practice widely.

B.The cells of patients are developed in healthy people.

C.Viruses entering the body can mix with host cells and form new DNA.

D.Both somatic and germline therapy have side effects on later generations.

3.What's the last paragraph mainly about?

A.The disadvantages of gene therapy.

B.The promising future of gene therapy.

C.The high costs of treatment procedures.

D.The issues related to viruses and complex genes.

4.What can be a suitable title for the text?

A.Why Gene Therapy Procedures Are Extremely Expensive

B.Gene Therapy: A Dangerous New After-operation Treatment

C.Gene Therapy: A Contemporary Progressive Treating Method

D.Scientists Are Accurate in Performing the Categories of Surgery

Many people take it for granted that black is a color of bad things while white should always mean something good．This may be because, in their opinion, black is related to darkness and white to purity．However, that is not always the case．Did you know that the same one color may mean something differently in different places of the world?

In the English-speaking world, black is the color of mourning—people wear black at the funeral．Red is concerned with danger or bloodshed（伤亡）．Yellow is the word for fear．If you are afraid, you are yellow．Yet none of these sayings is true outside the English-speaking world．In China and Korea white is the color of mourning．In Russia, China and some other countries, red stands for beauty, life and excellence．In Italy and Germany, you are yellow with anger, not with fear．

One does not have to cross an area to find color differences．Would you rather be red-blooded or a blue-blooded?

When people argue about whether coffee is good for health, they’re usually thinking of the health of the coffee drinker. Is it good for your heart? Does it increase blood pressure?

Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.

Traditionally, coffee bushes are planted under the canopy (树荫）of taller trees. However， more and more fanners in Latin America are deforesting the land to grow full-sun coffee. At first, this increases production because more coffee bushes can be planted if there aren5t any trees. With increased production come increased profits.

Unfortunately, deforesting for coffee production immediately decreases the local wildlife habitat, because native birds nest and hide from predators(捕食者）on the tall trees and migrating birds rest there.

Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides(杀虫剂)are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plants, and then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.

Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as “shade-grown” and ‘"bird-friendly”. Sure, these varieties might cost a little more. But we’re paying for the health of the birds, the land, ourselves, and the planet. I think it’s worth it.

1.How do farmers get more land to grow full-sun coffee?

A. They move to other countries.

B. They cut down trees.

C. They turn grassland into farmland.

D. They buy more land from other farmers.

2.Compared with the traditional method, what advantage does the full-sun method have?

A. It can increase the production of coffee.　　 B. It can promote peopled health.

C. It can provide more nests for birds.　　 D. It can protect the ecosystem.

3.Which opinion does the author agree with?

A. People should buy full-sun coffee.

B. Farmers should change the places to grow coffee.

C. Shade-grown coffee should be supported.

D. Pesticides should be forbidden in coffee planting.

4.What can we learn from the passage?

A. It is quite worthwhile to buy shade-grown coffee at any cost.

B. Farmers all have realized the importance of protecting the environment now.

C. The full-sun method does good to the health of human beings in the long run.

D. South American farmers are taking action to plant coffee bushes in the traditional way.
