All of us have felt pain, which can take complete control of our body and mind, making it impossible to move and even to think. Yet we need pain, without which we wouldn't know if we have hurt ourselves. It is our body's warning system, which tells us that we are injured and should do something about it.

    Pain is the most common reason we go to a doctor or other healer. It is the most common reason we take medicine. Until recently, however, most doctors knew of only a few drugs that stopped some pains. They knew little about the process of pain itself, about which, however, new knowledge is helping them learn to control pain better.

    Scientists have learned that the sense of pain is made up of both chemical and electrical signals, which travel from nerve cells (神经细胞) in the injured area, up the central nervous system to the brain. And back down again. Scientists also have learned that the nervous system sends two different kinds of pain message to the brain, one very fast, and the other slow.

    The first message is warning signal, which moves at a speed of 30 meters a second, and which travels to the middle part of the brain, and then to the outer part. In less than a second, the brain understands what part of our body is hurt and how badly it is injured. At a speed of only one meter a second moves the other message, which is the first step in the healing process, in which an important part is played by a very powerful material called prostaglandin, which are produced in almost every part of our body when needed. Scientists say prostaglandin raise and lower blood pressure, and also cause fever. When we hurt ourselves, the injured part produces a chemical that changes into prostaglandin, which cause the injured part to become red and swollen. and send the second, slower message of pain to the brain, which tells us not to use the injured part until it heals.

1In your opinion, the word “healer” in the passage refers to someone who isn't a _____________but much like him or her.

    A. nurse

    B. patient

    C. doctor

    D. chemist

2The English “________ ” in the passage can be translated into the Chinese “中枢神经系统”.

    A. central nervous system

    B. a powerful material

    C. the nervous system

    D. body's warning system

3Why does the brain know very well that we have hurt ourselves, and even what part of our body is hurt and even how it is injured, in less than a second? Because as soon as we hurt ourselves the warning signals will travel at once, at a speed of________ from nerve cells in the injured areas, up our central nervous systems to the middle and then to the outer part of our brains.

    A. 180 kilometers an hour

    B. 180 meters a minute

    C. 108 kilometers an hour

    D. 108 meters a minute

4Which of the following is true according to this passage?

    A. All doctors can take complete control of pain in different ways.

    B. Pain can control our body and mind completely.

    C. Prostaglandin, the most common drug, is known everywhere.

    D. Our injured parts can be used freely until they heal.

5Which of the following has the same meaning as “when needed” in the passage?

    A. In need of.

    B. If it needs.

    C. As it needed.

    D. If necessary.

 

答案:1C2A3C4B5D
解析:

1.    “Pain is the most common reason we go to a doctor or other healer.” 根据这句可知,本题选C。

2.    A是“中枢神经系统”的意思。

3.    根据短文,Warning signals的速度是30米/秒,换算过来即是C。

4.    信息句为 “All of us have felt pain, which can take complete control of our body and mind, making it impossible to move and even to think.”

A

One stormy night many years ago, an elderly man and his wife entered the hall of a small hotel in Philadelphia. Trying to get out of the rain, they came to the front desk hoping to get some shelter for the night.

“Could you possibly give us a room here?” the husband asked.

The clerk, a friendly man with a winning smile, looked at the couple and explained that there were three conventions in town.“All of our rooms are taken,” the clerk said.“But I can’t send a nice couple like you out into the rain at one o’clock in the morning. Would you perhaps be willing to sleep in my room? It’s not exactly a suite, but it will be good enough to make you folks comfortable for the night.”

When the couple declined, the young man pressed on.“Don’t worry about me; I’ll make out just fine.” the clerk told them. So the couple agreed.

As he paid his bill the next morning, the elderly man said to the clerk,“You are the kind of manager who should be the boss of the best hotel in the United States. Maybe someday I’ll build one for you.” The clerk looked at them and smiled. The three of them had a good laugh. As they drove away, the elderly couple agreed that the helpful clerk was indeed exceptional, as finding people who are both friendly and helpful isn’t easy.

Two years passed. The clerk had almost forgotten the incident when he received a letter from the old man. It recalled that stormy night and enclosed a round—trip ticket to New York, asking the young man to pay them a visit.

The old man met him in New York, and led him to the corner of Fifth Avenue and 34th street. He then pointed to a great new building there, a pale reddish stone, with turrets and watchtowers thrusting up to the sky.“That,” said the older man,“is the hotel I have just built for you to manage.”“You must be joking,” the young man said.“I can assure you I am not,” said the older man, a sly smile playing around his mouth.

The older man’s name was William Waldorf Astor, and that magnificent structure was the original Waldorf—Astoria Hotel. The young clerk who became its first manager was George C.Boldt. This young clerk never foresaw the turn of events that would lead him to become the manager of one of the world’s most glamorous hotels.

51.The purpose of the author writing this story is to_______.

A.give people a good laugh                         B.cover some facts

C.promote the business of Waldorf—Astoria Hotel       D.deliver a lesson

52.Which of the statements about the story is NOT true?

A.The story took place at about one a.m..

B.The old couple was too poor to afford a luxurious room.

C.The clerk was willing to help those in need.

D.The clerk received an unexpected invitation from the old man.

53.The underlined word “conventions” in Para.3 can be replaced by_______?

A.rooms       B.suites            C.meetings         D.hotels

54.Which of the following proverbs suits the story the best?

A.Every little thing helps.                                           B.Make hay while the sun shines.

C.Man proposes; God disposes(处理,决定).                   D.One good turn deserves another.
