东大大学英语（统考）在线练习题7(客观题)答案满分答案
1. Do you find getting up in the morning so difficult that it's painful? 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 work, you may say that you’re hot. That’s true. The time of day when you feel most energetic（有活力的）is when your cycle of body temperature is at its peak（高峰）. 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（自言自语）as: “Get up, John! You’ll be late for work again!” the possible explanation to the trouble is that John is at his temperature-and- energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these 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, maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract（对抗）your cycle by habitually staying up later than you want to. If your energy is low in the morning but you 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 and work better at your low point.
Get off to a slow start that saves your energy. Get up with a free yawn（哈欠） and stretch（伸展）. Sit on 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. 1). If a person finds getting up early a problem, most probably _______.
A. he is a lazy person

2. The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.
Sometimes advertising is intentionally misleading. A few years ago a brand of bread was offered to dieters（节食者）with the message that there were fewer calories（热量单位，大卡）in every slice. It turned out that the bread was not dietetic（适合于节食的）, but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.
On the positive side, emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.
