At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were   36   to show that we all have “a body clock”   37    us, which controls the   38   and fall of our body energies,   39   us different from one day one to the next.

The   40   of “a body clock” should not be too   41   since the lives of most living things are controlled   42   the 24 hour night-and-day cycle. We feel   43   and fall asleep at night and become   44   and energetic during the day. If the 24 hour-cycle is   45   , most people experience unpleasant   46   . For example, people who are not   47   to working at night can find that   48   of sleep causes them to   49   badly at work.

解析:

36 B

 上文提到本世紀(jì)初，科學(xué)家們就已經(jīng)發(fā)現(xiàn)人體不僅有血肉組成，還有時(shí)間。因此，根據(jù)這個(gè)發(fā)現(xiàn)，他們能夠證明在人體內(nèi)存在生物鐘。be anxious to do渴望做某事，此處沒有強(qiáng)調(diào)科學(xué)家的心理活動(dòng)，故排除。

37 A

 根據(jù)常識(shí)及文中第一句we’re built not just of flesh and blood but also of time.可知答案。

38 D

 空格上所缺詞應(yīng)與and后面的fall 構(gòu)成互補(bǔ)關(guān)系，才能較全面的概括人的活動(dòng)。

39 C

 結(jié)合前一句話中的controls可知，生物鐘能使我們每天的表現(xiàn)不一樣。show 證明，展示，指示；treat對(duì)待；change使改變。如選change就意為使我們發(fā)生變化,與上下文意思不符。

40 D

  “生物鐘”只是科學(xué)家經(jīng)過研究而得出的一種結(jié)論或觀點(diǎn)。

41 C

 根據(jù)空格后面的原因狀語從句可知答案。

42 B

 大部分有生命的動(dòng)物都受到日夜輪回這個(gè)時(shí)間循環(huán)的控制。

43 B

 結(jié)合常識(shí)可知，人工作一天,到晚上應(yīng)是比較勞累。另外，后面的fall asleep 應(yīng)是由勞累引起的。dreamy多夢(mèng)的，不應(yīng)出現(xiàn)在fall asleep之前。

44 C

 人休息了一晚上，第二天又充滿了生機(jī)、活力。

45 A

 如果時(shí)間循環(huán)被打亂，大部分人就會(huì)不舒服。

46 B

 結(jié)合下一句的例子可知，此處應(yīng)為人感到不舒服。

47  D

 be used to doing something習(xí)慣于……。上文中提到人的生物鐘如被打亂，可能會(huì)感到不舒服。所以，如果不習(xí)慣于在晚上工作的人如果晚上工作，工作就會(huì)做不好。

48 C

 lack此處為名詞，在從句中做主語，lack of…缺乏……。

49 A

 perform工作；表現(xiàn)。

50 B    

 根據(jù)后面的also可得知答案。

51 D

 人類的日夜循環(huán)分為兩段時(shí)間：即睡眠時(shí)的時(shí)間和醒著的時(shí)間。

52 C

 根據(jù)后面的longer than one day 可知，此處last意為持續(xù)。

53 A

 大部分人都有這種體驗(yàn)，都同意這種看法。

54 D

 上文提到了some days與之相對(duì)應(yīng)的是other days即others。

55 A

 此處just用于否定句中表強(qiáng)調(diào),它們根本就不存在。

One day, a poor boy who was trying to pay his way through school by sending newspapers door to door, was so hungry that he decided to beg for a meal at the next house.
However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?”
“You don’t owe me anything,” she replied. “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.
Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.
At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words:
“Paid in full with a glass of milk, Dr. Howard Kelly.”
Tear of joy flooded her eyes.

D

It is the season for long lines and frayed (緊張的) nerves. Here’s how to deal.

Lighten up

Do youreslf a favor and ship(運(yùn)送) your presents. Nearly every U.S. airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.

Weigh your options

Now knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.

Leave amateurs（不熟練者） in the dust

Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced fliers, and it’s a hard walking. Plus, if you decide to cut it close, you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.

Take it public

The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories(地產(chǎn)) have increased dramatically. True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.

Say no to bumper cars

Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX, now feature this sensible choice.

68.Airlines have reduced flights to_________.

A. deal with crisis                         B. reduce the time for leave

C. lower the cost                          D. provide more job chances

69. We can learn from the passage that____      .

A. taking a taxi at the airport is expensive

B. taxis stay at the airport free of charge

C. cars can park at the airport for free

D. JFK encourages people to take a taxi

70. What’s the best title for the passage?

A. 5 Ways to Survey a Holiday Flight.             B. Good Seasons for Flight

C. Cars at the Airport                     D. How to Board a Flight

I will never forget what my old headmaster taught me. Normally when you are only 15          years of age you do not remember most of the things that are taught by your teachers. But this particular story is one such lesson that I will never forget. Every time I drift off course, I get reminded of this story.

It was a normal Monday morning, and he was making a speech to the students on important things in life and about devoting ourselves to what is important to us. This is how the story went:

An old man lived in a certain part of London, and he would wake up every morning and go to the subway. He would get the train right to Central London, and then sit at the street corner and beg. He would do this every single day of his life. He sat at the same street corner and begged for almost 20 years. His house was dirty, and a stench(惡臭)came out of the house and it smelled horrible. The neighbors could not stand the smell any more, so they asked the police officers to clear the place. The officers knocked down the door and cleaned the house. There were small bags of money all over the house that he had collected over the years.

The police counted the money, and they soon realized that the old man was a millionaire. They waited outside his house to tell the good news to him. When he arrived home that evening, he was met by one of the officers who told him that there was no need for him to beg any more as he was a rich man now, a millionaire. He said nothing at all; he went into his house and locked the door. The next morning he woke up as usual, went to the subway, got into the train, and sat at the street corner and continued to beg. Obviously, this old man had no great plans, dreams or anything important for his life. We learn nothing from this story other than staying focused on the things we enjoy doing.

59. The headmaster told the story to the students to__________.

A. make the students relaxed in the lesson             B. remind the students to think deeply

C. show how poor the old man was                            D. encourage the students to become rich

60. After hearing what the officer said, the old man_________.

A. believed the officer was playing a joke on him. B. didn't know many people respected him a lot.

C. was very angry to find his house broken into.     D. was not so excited as the officer had expected.

61. What did the author learn from the story?

A . One should devote himself to his dream.            B. The old man was foolish not to stop begging.

C. What the headmaster taught was very important.

D. People must have a plan before taking action.

62. Which word can best describe the author's attitude towards the old man?

A. Pity.           B. Disappointment.                 C. Respect.          D. Anger.

63. We know from the passage that ___________________.

the author had a big dream at the age of 15.         

B. the headmaster was popular with the students.

the old man begged every day without stopping.  

D. the neighbors took great pity on the old man.
