"Freshman fifteen" is a term which means fifteen pounds, or about seven kilograms— the wei

ght students might expect to gain in their first year of college. People used to talk about the "freshman ten." Before that, it was the "freshman five." Are freshman more inflated, or just the expression？ The fact is, many young men and women do put on extra weight when they start college. Some schools that have done research on the issue including Cornell University in Ithaca, New York, have found that freshmen gain an average of four pounds during their first twelve weeks, the equivalent of two kilograms. If weight gain continues at this rate, how long before they put on fifteen pounds？ The answer is forty-five weeks, or almost a year. The next question is, why do so many freshmen gain weight？ The answers listed by experts are not so surprising. One is poor diet: College students often eat foods high in fat and sugar and starch with no parents around to say no to junk food. Students may also miss meals. They could be in class or studying or just ... busy. In any case, those who miss meals are more likely to overeat when they do have food. Also, freshmen often use food to put their mind at ease. They have college pressures to deal with. Not only that, many are living away from home for the first time. Another reason college students gain weight is that they often do not get enough exercise. Finally, there is something else that can add up to the "freshman five" or ten or fifteen, alcohol. Alcohol is high in calories and this is especially true of beer. And, no, freshmen are not supposed to be drinking, not unless they are twenty-one, the legal drinking age in America. For many college students, the extra weight they put on in their freshman year can be as hard to escape as term papers and final exams.

Paragraph 1 is centered on______.

A．why freshmen put on weight in college

B．why freshmen worry about their weight

C．how the "freshman fifteen" gets its name

D．how the "freshman fifteen" amazes freshmen

Do you find it very difficult and painful to get up in the morning? This might be call

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 your 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 quarrelling 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 if 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 you have an important 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 requiring more energy or concentration for your sharper hours.

21.If a person finds getting up early a problem, most probably ________.

A.he is a lazy person.

B.he refuses to follow his own energy cycle.

C.he is not sure when his energy is low.

D.he is at his peak in the afternoon or evening.

22.Which of the following may lead to family quarrels according to the passage？

A.Unawareness of energy cycles.

B.Familiar monologues.

C.A change in a family member’s energy cycle.

D.Attempts to control the energy cycle of other family members.

23.If one wants to work efficiently at his low point in the morning, he should __________.

A.change his energy cycle
