题目

阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项 Most people think that regular (有规律的) exercise does health wonders for people, but what exactly are its health benefits (益处)? To start with, research suggests regular exercise can help make people's body strong. It helps cut down on the number of different diseases people face each year. Regular exercise throughout the year helps the working quality of people's heart become better and lower blood pressure. During exercise, people's heart must work harder so that it can make blood go throughout the body. This extra effort makes it grow stronger over the long term. At the same time, as little as 30 minutes per day can help to lower blood pressure. It helps move away things that are all linked to having high blood pressure. Exercise has a good effect on people's mind and spirit too. If you are suffering from stress and sadness, regular gentle exercise is one way to improve your full sense of happiness. The way that exercise improves people's mental state is by moving away the bad effect of stress that swims into their bodies, helping them find deep calm. Some studies even show that exercise keeps people's skin fit. Exercise helps keep skin cells alive and healthy by increasing blood flow. Blood carries oxygen and nutrients to working cells throughout the body, including the skin. In addition to providing oxygen, blood flow also helps carry away waste products. You can think of it just like cleaning your skin from the inside. However, we should know that when suffering from an illness, try not to finish all your plan for exercise. The body needs time to recover. Strong exercise can be harmful to the immune system (免疫系统) when it is already under pressure. Instead, take a gentle walk when falling ill to help recovery.
