Life is to be enjoyed. There's no point in giving up something you enjoy unless you get something back that's even better. When people eat more healthfully, exercise, quit smoking, and manage stress better, they find that they feel so much better that it reconstructs the reason for making these changes from fear of dying to joy of living. The latest studies show that when you exercise and eat right: YOUR BRAIN receives more blood flow and oxygen, so you become smarter, think more clearly, have more energy, and need less sleep. Two studies showed that just walking for three hours per week for only three months caused so many new neurons to grow that it actually increased the size of people's brains! YOUR FACE receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, chronic emotional stress and smoking reduce blood flow to your face so you age more quickly. Smoking accelerates aging because nicotine causes your arteries to narrow down, which decreases blood flow to your face and makes it wrinkle earlier. This is why smokers look years older than they really are. YOUR GENES change. In May, a study was published in the Proceedings of the National Academy of Sciences showing that changing your lifestyle changes your genes. YOUR TELOMERES get longer. Telomeres are the ends of our chromosomes that control how long we live. As telomeres become shorter, then cells age more quickly, thus shortening your life. Besides, one of the most interesting findings in the study was that the mothers' awareness of stress was more important than what was really occurring in their lives. The researchers gave the women a questionnaire and asked them to rate on a three-point scale how stressed they felt each day, and how out of control their lives felt to them. The women who were aware that they were under heavy stress had significantly shortened and damaged telomeres compared with those who felt more relaxed. On the contrary, some of the women... The best title for the passage would be _ . A) Eat better, live better B) Feel better, live longer C) Less stress, fewer diseases D) Smoke more, age sooner

Smoggy weather has become common in China. But these days, air pollution levels in the north eastern city of Harbin surpassed the previous record levels. The city was essentially shut down after PM2. 5, fine Particulate pollution that is considered hazardous . reached levels of 1000 micrograms per cubic meter-40 times the safety level remended by the World Health Organization.

Lucky is the man who has no "skeleton in his closet." When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a "skeleton in his closet." Some people may have more than one skeleton. As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England. Before 1832, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse of an executed criminal. But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices. We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor keep his skeleton in some dark corner where it could not be seen, or hide it in a closet. After a time, people began to suspect every doctor of hiding a skeleton in the closet. From this suspicion, the phrase"a skeleton in the closet"took on a broader, more general meaning: to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory. One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man's guess is as good as another. But this sounds like a story by the great French novelist, Balzac. Balzac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly... Which of the following situations is now suitable for using the phrase "skeleton in the closet"? A) You have stolen something precious and hide them in the closet. B) You are a doctor and have to keep a skeleton for research. C) If you have cut open a dead human body for scientific examination you should keep the skeleton secret. D) You have done a crime or done something foolish, but you want to keep others from discovering it.
