Aspirin may be the most familiar drug in the world — but its power to heal goes far beyond the usual aches and pains. Exciting new studies suggest that aspirin can help fight a wide range of serious illnesses. "It now seems to be a benefit in so many areas of health," says Dr Debra Judelson, medical director of the Women's Heart Institute in Beverly Hills, California. "I advise most of my patients, as long as they aren't allergic to aspirin and don't have bleeding problems, to take low-dose aspirin."

These who have a passion【C1】______climbing high and difficult mountains are often【C2】______with astonishment. Why are men and women【C3】______to suffer cold and hardship, and to【C4】______on high mountains？ This astonishment is caused, probably, by the difference between mountaineering and other forms of activity【C5】______which men give their leisure. Mountaineering is a sport and not a game. There are no man-made rules, as there are for【C6】______games as golf and football. There are, of course, rules of different kinds which it would be dangerous to【C7】______, but it is this freedom from man-made rules【C8】______makes mountaineering attractive to many people.

E.J. Masicampo and Roy Baumeister of Florida State University discovered this by doing some experiments on that most popular of laboratory animals, the impoverished undergraduate. They asked 121 psychology students who had volunteered for the experiment to watch a silent video of a woman being interviewed that had random words appearing in bold black letters every ten seconds along the perimeter of the video. This was the part of the experiment intended to be mentally taxing. Half of the students were told to focus on the woman, to try to understand what she was saying, and to ignore the words along the perimeter. The other half were given no instructions. Those that had to focus were exerting considerable serf-control not to look at the random words. When the video was over, haft of each group was given a glass of lemonade with sugar in it and half was given a glass of lemonade with sugar substitute. Twelve minutes later, when the glucose from the lemonade with sugar in it had had time to enter the students' blood, the researchers administered a decision-making task that was designed to determine if the participant was using intuition or reason to make up his mind. The students were asked to think about where they wanted to live in the coming year and given three accommodation options that varied both in size and distance from the university campus. Two of the options were good, but in different ways: one was far from the campus, but very large; the other was close to campus, but smaller. The third option was a decoy, similar to ope of the good options, but obviously not quite as good. ff it was close to campus and small, it was not quite as close as the good close option and slightly smaller, if it was far from campus and large, it was slightly smaller than the good large option and slightly farther away. Psychologists have known for a long time that having a decoy option in a decision-making task draws people to choose a reasonable option that is similar to the decoy. Dr. Masicampo and Dr. Baumeister suspected that students who had been asked to work hard during the video and then been given a drink without any sugar in it would be more likely to rely on intuition when making this decision than those from the other three groups. And that is what happened; 64% of them were swayed by the decoy. Those who had either not had to exert mental energy during the showing of the video or had been given glucose in their lemonade, used mason in their decision-making task and were less likely to be swayed by the decoy. It is not clear why intuition is independent of glucose. It could be that humans inherited a default nervous system from other mammals that was similar to intuition, and that could make snap decisions about whether to fight or flee regardless of how much glucose was in the body. Whatever the reason, the upshot seems to be that thinking is, indeed, hard work. And important decisions should not be made on an empty stomach.

Families share many activities. Homes have spaces for people to be together. Families have meals together in the kitchen or dining room. They play games, watch TV, or talk with friends in the living room. Every family's home is special. People can decorate their homes with things they like. They put the furniture the way they want it. They use colors they like. The children often fix up a space with their own things. They hang posters or art projects from school over their beds. They have a place for things they collect. Their homes tell about them. 1)、People often go to the cinema when they want to be alone. A.T B.F 2)、Families have meals together in their dining-room.
