There is an English saying: “ 1. .” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body.   2. 

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise.   3. . If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐) the pain for the longest time was the group which listened to a funny program. 4. 

__5.__. They have found that even if their patients do not really feel like laughing, making them smile

is enough to produce beneficial effects similar to those caused by laughter.

A．Laughter can prolong one’s life.

B．As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients’ condition by encouraging them to laugh.

C．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.

D．It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in

the face, the stomach and even the feet.

E. Although laughter helps cure the disease, doctors still can not put this theory into clinic practice.

F. Laughter is the best medicine.

G. They have found that laughter really can improve people’s health.

 

 “BANG!” the door caused a reverberation (回声)．It was just standing there, with Father standing on one side, and I on the other side．

We were both in great anger．“Never set foot in this house again!” stormed Father．With tears welling up in my eyes, I rushed out of the flat and ran along the street．

The street lights were shining rather desolately(凄凉的)．I wandered aimlessly．

A young father who held a child in his arms walked past me．I felt as if I saw my childhood from another space: happy and harmonious．

But now… I don’t know whether it is because I have grown up or because dad is getting old．We differ in our ways of thinking．He always imposes his opinions and codes of behavior on me．Whenever I do something wrong, he never admits it．We are just like two people coming from two different worlds．It feels like there is an iron door between us that can never be opened．

I wandered the streets, without a destination in mind．My heart was frozen on this hot summer night．As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company．When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on．

In fact, it was nothing．Perhaps, dad was throwing away some of his old stamps．Perhaps he thought they were useless．I never had the courage to tell him that I liked collecting stamps．I can’t stand his outrageous(蛮横的) words: “ I can throw you away, let alone these old papers．”

All the lights were off except father’s．

Dad was always like this．Maybe he didn’t know how to express himself．After shouting at me, he never showed any mercy or any moments of regret．After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers．

This was how he always was．He has been a leader for so long that telling everyone else what to do has become his second nature．

The light was still on．“Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been．At last, I decided to open the door．As soon as I opened the door, tears ran down my cheeks．I suddenly realized that the iron door that I had imagined between us did not exist at all．Love – is second to none．

1.Decide which is the best order of the following according to what happened in the passage．

a．I opened the door and entered the house．

b．Sadly I ran out into the street．

c．I reached the place where I lived and saw my house still brightly lit．

d．I thought of my father’s kindness towards me．

e．I walked about in the street without any aim．

A．b, e, d, c, a                 B．b, e, c, d, a                 C．b, e, a, c, d                 D．b, e, c, a, d

2.What made the writer think of his childhood?

A．The sight of the desolate street lights．

B．The sight of the empty street．

C．The sight of a father with a child in his arms．

D．The sight of light in his own house．

3.Why do you think the father often shouts at his son?

A．Perhaps the father is getting older and older．

B．Perhaps the son has already grown up．

C．Perhaps they never agree with each other．

D．Perhaps the father has got used to doing that．

4.What conclusion can you draw after reading the passage?

A．The father is actually kind to his son．

B．The father treats his son in an unfair way．

C．The father is neither kind nor cruel to his son．

D．The father is always finding fault with his son．

 

There is an endless supply of stories about sleepwalkers (梦游者). People have been said to climb on roofs, solve mathematical problems, write music, walk through windows, and do murder in their sleep.

       In Revere, Massachusetts, a hundred policemen searched for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there.

       At the University of Lowa, WWW.K**S*858$$U.COMa student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Lowa River. He would take a swim and then go back to his room to bed.

       An American expert on sleep claims (声称) that he has never seen a sleepwalker. He is said to know more about sleep than any other living man, and during the last thirty-five years he has lost a lot of sleep watching people sleep. He says, “Of course, I know that there are sleepwalkers because I have read about them in the newspapers. But none of my sleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, I doubt whether I would get many takers (应征者).”

       Sleepwalking, however, is a scientific reality. It is one of those strange things that sometimes look quite fantastic (怪诞的). Doctors say that sleepwalking is much more common than is generally supposed. Many sleepwalkers do not try to find help and their sleepwalking is never recorded.

Generally speaking, sleepwalkers are people who ________.

      A. climb on roofs                                B. walk through windows

       D. was searched for by policemen when he lost his way

There was a college student who got into the habit of ________.

      A. getting up in the middle of the night and walking down to the river

       B. walking three-quarters of a mile every day

       C. swimming in the Lowa River before going to bed

       D. walking about before he went to bed

Why do people think sleepwalking is nothing but a fantastic thing which doesn’t have any explanation?

      A. It is so common that it needn’t be recorded.

       B. Scientists take no interest in it.

       C. Most sleepwalkers do not seek help for their problem.

       D. No records about it have been made.

You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.

  When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

  In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the back of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.

  Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can resist massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

1.What does the author say about the black box?

A. It ensures the normal functioning of an airplane.

B. The idea for its design comes from a comic book.

C. Its ability to resist disasters is incredible.

D. It is an indispensable device on an airplane.

2. What information could be found from the black box on the Yemeni airliner?

A. Data for analyzing the cause of the crash.

B. The total number of passengers on board.

C. The scene of the crash and extent of the damage.

D. Homing signals sent by the pilot before the crash.

3.Why was the black box redesigned in 1965?

A. New materials became available by that time.

B. Too much space was needed for its installation.

C. The early models often got damaged in the crash.

D. The early models didn't provide the needed data.

4. Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?

A. To distinguish them from the colour of the plane.

B. To caution people to handle them with care.

C. To make them easily identifiable.

D. To conform to international standards.

5.What do we know about the black boxes from Air France Flight 447?

A. There is still a good chance of their being recovered.

B. There is an urgent need for them to be reconstructed.

C. They have stopped sending homing signals.

D. They were destroyed somewhere near Brazil.

 

 

The other day I heard a few local musicians talking, "I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm (韵律).""Nobody wants to pay musicians anything. I’m sick of all the people who want you to play without paying you.” One younger musician said, "There are a couple of clubs who want me to play for a few nights a month, and I’m trying to find other places to play. I’m also planning to join in several summer festivals this year." I really liked what the younger musician said so I made friends with him.

Attitudes are important. Whether they’re positive or negative (消极的), they’re all rubbing off on you. If you’re around people who are always complaining(抱怨) or blaming (责备) others, it is possible that you will start doing the same as well. If you spend lots of time with people who don’t support your dreams, it is time to take a look at the people you call "friends".

There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don’t become friends with people who fall below that standard. The choice is always yours to make. Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream.
