单选题Do you find it very difficult and painful to get up in the morning? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labor through your work you may say that you're "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as: "Get up, Peter! You'll be late for work again!" The possible explanation to the trouble is that Peter is at his temperature-and-energy peak in the evening. Much family quarrel ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning, but yon have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point. Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

单选题 {{B}} Text{{/B}} After 20 years of marriage, a husband may still not understand his wife. How is it that she is never at a {{U}}(26) {{/U}} for words? How can she {{U}}(27) {{/U}} the names of a couple they met on {{U}}(28) {{/U}} years ago? Now we know {{U}}(29) {{/U}} to tell him: It's her brain. Although there are obviously cultural {{U}}(30) {{/U}} for the differences in emotions and behavior, {{U}}(31) {{/U}} breakthrough research reveals that the {{U}}(32) {{/U}} of many puzzling differences between men and women may {{U}}(33) {{/U}} in the head. Men's and women's brains {{U}}(34) {{/U}} much in common, but they are definitely not the same {{U}}(35) {{/U}} size, structure or insight. Broadly speaking, a woman's brain, like her body, is ten to fifteen percent smaller than a man's, {{U}}(36) {{/U}} the regions dedicated to the language may be more densely {{U}}(37) {{/U}} with brain cells.

At every age, women's memories {{U}}(40) {{/U}} men's. They have a greater ability to {{U}}(41) {{/U}} names with faces than men do, and they are {{U}}(42) {{/U}} at recalling list. The events people remember best are those that an emotion is attached to. {{U}}(43) {{/U}} women use more of their right brains, which {{U}}(44) {{/U}} emotions, they may do this automatically. While we don't yet know what all these findings imply, one thing is {{U}}(45) {{/U}} : Male and female brains do the same things, but they do them differently.

单选题 Questions 22-25 are based on a conversation you are going to hear.

单选题Fishing adds only about one percent to the global economy, but on a regional basis it can contribute extremely to human survival. Marine fisheries contribute more to the world''s supply of protein than beef, poultry or any other animal source. 　　Fishing typically does not need land ownership, and because it remains, generally, open to all, it is often the employer of last resort in the developing world―an occupation when there are no other choices. Worldwide, about 200 million people rely on fishing for their livelihoods. Within Southeast Asia alone, over five million people fish full-time. In northern Chile forty percent of the population lives off the ocean. In Newfoundland most employment came from fishing or servicing that industry ― until the collapse of the cod fisheries in the early 1990s left tens of thousands of people out of work. 　　Though debates over the conservation of natural resources are often cast as a conflict between jobs and the environment, the restoration of fish populations would in fact boost employment. Michael P. Sissenwine and Andrew A. Rosenberg of the U. S. National Marine Fisheries Service have estimated that if depleted species were allowed to rebuild to their long-term potential, their sustainable use would add about ＄ 8 billion to the U. S. gross domestic product ― and provide about 300 000 jobs. If fish populations were restored and properly managed, about twenty million metric tons could be added to the world''s annual catch. But restoration of ecological balance, fiscal profitability and economic security will require a continual reduction in the capacity of the commercial fishing industry so that wild populations can recover. 　　The necessary reductions in fishing workforce need not come at the expense of jobs. Governments could increase employment and reduce the pressure on fish populations by guiding subsidies away from highly mechanised ships. For each ＄ 1 million of investment, industrial-scale fishing operations　require only one to five people, while small-scale fisheries would employ between 60 and 3 000. Industrial fishing itself threatens tens of millions of fishermen working on a small scale by depleting the fish on which they depend for subsistence.
