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’re “hot”. That’s true. The time of day when you feel the 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 (自言自語) as John talks to himself: “Get up, John! You’ll be late for work again!” The possible explanation for 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 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. Adjust your cycle to some extent by 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 (打起精神) and work better at your low point.

Begin with a slow start which saves your energy. Get up with a slow 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 usual work in the afternoon and spend time doing important work for your high peak hours.

1.According to Dr. Kleitman if you don’t want to get up in the morning ____________.

A. you must be a lazy person

B. you must catch a cold

C. your energy cycle must be low

D. you should stay in bed

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

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

B. Familiar monologues.

C. Unawareness of energy cycles.

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

3.If one wants to work better at his low point in the morning, he should ____________.

A. change his energy cycle

B. go to bed earlier

C. overcome his laziness

D. get up earlier than usual

4.You are advised to rise with a yawn and stretch because it will _________________.

A. help you to control your temper early in the day

B. help to keep your energy for the day’s work

C. enable you to concentrate on your routine work

D. keep your energy cycle under control all day

Like many new graduates, I left university full of hope but with no real idea of what I wanted to do. My degree, with honors, in English literature had not really prepared me for anything practical. I knew I wanted to make a difference in the world somehow, but I had no idea how to do that. That’s when I learned about the Lighthouse project.

I started my journey as a Lighthouse Project volunteer by reading as much as I could about the experiences of previous volunteers. I knew it would be a lot of hard work, and that I would be away from my family and friends for a very long time. In short, I did not take my decision to apply for the Lighthouse Project lightly, neither did my family.

Finally, however, I won the support of my family, and I sent in all the paperwork needed for the application (申請). After countless interviews and presentations, I managed to stand out among the candidates and survive the test alone. Several months later, I received a call asking me to report for duty. I would be going to a small village near Abuja, Nigeria.

After completing my training, I was sent to the village that was small and greatly in need of proper accommodation. Though the local villagers were poor, they offered their homes and food as if I were their own family. I was asked to lead a small team of local people in building a new schoolhouse. For the next year or so, I taught in it. But I sometimes think I learned more from my students than they did from me.

Sometimes during that period, I realized that all those things that had seemed so strange or unusual to me no longer did, though I did not get anywhere with the local language, and I returned to the USA a different man. The Lighthouse Project had changed my life forever.

D. attended special training to finish difficult tasks.

3.The underlined word “accommodation” in paragraph 4 means ________________.

B. English teachers.

C. living places and food

D. teaching buildings.

4.What can we infer from the author’s experiences In Nigeria?

A. He was chosen as the best teacher by his students.

C. He had learned to communicate in the local language.

D. He had overcome all his weakness before he left for home.
