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 labor through your work you may say that you are“hot”. That’s true. The time of day when you feel most energetic（精力充沛的）is when your cycle of body temperature is at this peak（高峰）. For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so，but it leads to such familiar words as：“Get up，John！You’ll be late for work again！”The possible explanation to the trouble is he 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 it better. Habit can help，Dr. Kleitaman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract（对抗）your cycle to some extent by habitually（习惯性地）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 steam and work better at your low point.

Get off to a slow start，which saves your energy. Get up with a leisurely yawn（呵欠）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 for your sharper hours.

1．According to the passage，family quarrels may result from _____________.

A．unawareness of different energy cycles

B．the same energy cycle of family members

C．failing to get up early in the morning

D．knowledge of energy cycles

2．If you are used to getting up late in the morning，you are likely to be most energetic __________.

A．in the morning 　 B．at noon　 C． in the evening　 D．in the afternoon

3．What’s the likely relationship between energy cycle and body temperature？

A．Energy cycle and body temperature are the same things.

B．The higher your temperature is，the less energetic you are.

C．There is no direct relation between them.

D．The higher your temperature is，the more energetic you are

4．Which of the following statements is not true？

A．One can change his energy cycle once he makes up his mind.

B．We still don’t know why people have different energy cycles.

C．Habits will help to make our life fit energy cycles better.

D．If you rise earlier than usual，you will be more efficient at your low point in the morning.

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。

　　Without most people realizing it, there has been a revolution in office work over the last ten years．Before that time, large computers were only used by large, rich companies that could afford the investment．With the advancement of technology, small computers have come onto the market, which are capable of doing the work that used to be done by much larger and expensive computers, so now most smaller companies can use them

　　The main development in small computers has been in the field of word processors(处理器), or WPS as they are often called．40% of British offices are now estimated to have a word processor and this percentage is growing fast．

　　There are many advantages in using a word processor for both secretary and manager．The secretary is freed from a lot of daily work, such as re-typing letters and storing papers．He or she can use this time to do other more interesting work for the boss．From a manager’s point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours．

　　But is it all good？If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed．Another worry is the increasing medical problems related to work with visual display units(显示器)．The case of a slow loss of sight among people using word processors seems to have risen greatly．It is also feared that if a woman works at a VDU for long hours, the unborn child in her body might be killed．Safety screens to put over a VDU have been invented but few companies in England bother to buy them．

　　Whatever the arguments for and against word processor, they are a key feature(特征)of this revolution in office practice．

(1)

[　　]

It can be concluded from the passage that ________．
[　　]

As soon as the complainer was out of the store，my grandmother would call me to stand in front of her.Then she would say the same thing she had said at least a thousand times，it seemed to me.“Jane，did you hear what so－and－so complained about？”And I would nod.Grandmother would continue，“Jane，there are people who went to sleep all over the world last night，poor and rich and black and white，but they will never wake again.Those dead people would give anything，anything at all for just five minutes of this weather that person was complaining about.So you watch yourself about complaining，Jane.What you're supposed to do when you don't like a thing is change it.If you can't change it，change the way you think about it.Don't complain.”

You're lost in the world of dreams and sleep. You roll over, smiling as you come across a swimming pool filled with chocolate. And then, your wonderful dream becomes a nightmare(噩梦) when someone is screaming, “Get up！” It's just what every teenager goes through each morning!

Now, there seems to be one school that finally understands that requiring teens to show up at 9 am is not just cruel but also harmful to both the kids and the school.

Monkseaton High School in North Tyneside, Britain, recently decided to experiment to see if there is any difference in student behavior if they just pushed back the start of their day by one hour, from 9 am to 10 am. And the results are surprising.

Since carrying out the later start, Monkseaton has seen a 28% drop in truancy,_even hardly any lateness, and best of all, higher test scores. One of the reasons is that the teenagers are much happier to have the extra hour of sleep, but there is also a scientific reason behind why they need the extra sleep.

The school's decision to push back the time was based on the research done by Oxford Professor Russell Foster, who pointed out that teenagers and adults have different sleep cycles，explaining why teenagers go to bed late and wake up late.

While adults are wide awake and ready at 8 am, teenagers are not fully awake until 10 am, sometimes even noon. Teachers may argue that their students perform better in the morning, but in fact, it is because they are in the zone while their students are still sleepy, making the students easier to control.Memory tests prove that the more difficult classes should be in the afternoon when teenagers are most wide awake.

The Monkseaton school officials are encouraged by the results and plan on voting to make it a permanent change.

36．What's the meaning of the underlined word “truancy”？

A．Grades. B．Classes.

C．Absence. D．Practice.

37．What can we learn from the passage?

A．Teenagers and adults have the same sleep cycle.

B．Teenagers are fully awake at 10 am as a whole.

C．Teenagers are much happier to sleep than study.

D．Teenagers need the extra sleep also for a scientific reason.

38．Which of the following statements is NOT true according to the passage?

A．Monkseaton High School is satisfied with the result of the experiment.

B．It is very cruel for the teenagers to show up in class at 9 am every day.

C．Monkseaton High School plans to change the school time forever.

D．In fact, teenagers perform better in the morning than in the afternoon.

39．What's the best title for this passage?

A．Get up early, teenagers!

B．Finally, a school understands teenagers

C．Why do teenagers stay up late?

D．Differences between teens and adults
