科目:高中英語 來源: 題型:閱讀理解

The Olympic Games are seen as the greatest test of an athlete’s ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began.

       In the early years, athletes ate mushrooms(蘑菇)and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping(服用興奮劑).

       Just last month, Britain’s top sprinter(賽跑選手) Dwain Chambers and several American athletes tested positive(呈陽性)for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how ho test for it.

       “We’re like cops(警察)chasing criminals—athletes are always adapting and looking for areas we haven’t investigated,” said Jacquew de Ceaurriz, a French anti-doping expert.

       Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson.

He broke the 100 meters world record in winning gold at the 1988 Seoul(漢城)Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action—only to be found positive again and banned forever.

China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes—seven of them swimmers—tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again.

Experts are also worried that doping can damage a person’s health. It is believed to increase the risk of liver and kidney(肝腎)diseases, and women may experience reproductive(生育) problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene(基因)technology.

“For the moment, genetic doping does not exist,” said de Ceaurriz. “Even in 10 or 15 years it will not be done easily—the scientific community(界)will not let it happen.”

Which of the following is not the way that some athletes cheat to their better sports achievements?

A. Eating mushrooms.    B. Taking drug THG. 

C. Taking genetic doping.   D. Eating plant seeds.

How many countries are mentioned in the passage in which there were athletes doping?

A. Two.                 B. Four.                C. Sic.                  D. Eight.

We can infer from the passage that ____.

A. scientists get a lot of information about drugs before the athletes take doping

B. taking doping will never happen again because of the serious test

C. few athletes used drug cheats before the first drugs test was carried out at the 1968 Olympics

D. problems with drug cheats are still serious though they are severely tested

Which statement of the following is true?

A. Many police are sent to chase criminals of taking doping during the Olympic Games.

B. The drug test was carried out until the 1968 Olympics.

C. There is the possibility that women athletes taking doping will give no birth to a child.

D. Ben Johnson was banned from sports forever for being tested positive for drug use at the 1988 Seoul Olympics.

下面是幾則寓言小故事:

An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, aiming at the dove. The ant, perceiving his design, stung him in the foot. In pain the birdcatcher shouted, and the noise made the dove take wing.

Two men were travelling together, when a bear suddenly met them on their path. One of them climbed up quickly into a tree and hid himself in the branches. The other, seeing that he must be attacked, fell flat on the ground, and when the bear came up and felt him with his snout, and smelt him all over, he held his breath, and pretended to be dead as much as he could. The bear soon left him, for he will not touch a dead body. When he disappeared, the other traveller descended from the tree, and asked his friend what it was the bear had whispered in his ear. “He gave me this advice,” his companion replied. “Never travel with a friend who deserts you at the approach of danger.”

A prince had some monkeys trained to dance. Being naturally good at learning, they showed themselves excellent pupils, and in their rich clothes and masks, they danced as well as any of the courtiers. Their performance was often repeated with great applause, till on one occasion a courtier, bent on mischief, took from his pocket a handful of nuts and threw them upon the stage. The monkeys at the sight of the nuts forgot their dancing and became (as indeed they were) monkeys instead of actors. Pulling off their masks and tearing their robes, they fought with one another for the nuts. The dancing spectacle thus came to an end in the laughter and ridicule of the audience.

A cock was once strutting up and down the farmyard among the hens when suddenly he noticed something shining in the straw. "Ho! ho!" said he, "that’s for me," and soon rooted it out from beneath the straw. It turned out to be a pearl that by some chance had been lost in the yard. “You may be a treasure,” signed the cock, “to man, but for me I would rather have a single barley-corn.”

An old man on the point of death summoned his sons around him to give them some parting advice. He ordered his servants to bring in a bunch of sticks, and said to his eldest son: "Break it." The son tried hard, but with all his efforts was unable to break the bundle. The other sons also tried, but none of them was successful. “Untie it,” said the father, “and each of you take a stick.” When they had done so, he called out to them: “Now, break,” and each stick was easily broken.

請(qǐng)閱讀下面的故事寓意,然后匹配與之對(duì)應(yīng)的小故事。

A. Not everything you see is what it appears to be.

B. One man’s pleasure may be another’s pain. / One man’s meat is another’s poison,

D. One good turn deserves another.

E. Union gives strength.

科目:高中英語 來源:2011年浙江普通高等學(xué)校招生全國(guó)統(tǒng)一考試英語試卷 題型:閱讀理解

One evening in February 2007 . a student named Paula Ceely brought her car to a stop on a remote in Wales . She got out to open a metal gate that blocked her path . That's when she heard the whistle sounded by the driver of a train.Her Renault Clio parked across a railway line. Second later,she watched  the train drag her car almost a kilometre down the railway tracks.
Ceely's near miss  made the news because she blamed it on her GPS device(導(dǎo)航儀).She had never driven the route before .It was dark and raining heavily . Ceely was relying on her GPS. But it made no mention of the crossing ."I put my complete trust in the device and it led me right into the path of a speeding train ,"she told the BBC.
W ho is to blame here ? Rick Stevenson ,who tells Ceely's story in his book When Machines Fail US, finger at the limitations of technology. We put our faith in digital devices, he says,
but our digital helpers are too often not up to the job. They are filled with small  problems. And it’s not just GPS devices: Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless key boards.
The problem with his argument in the book is that it’s  not clear why he only focuses digital technology,while  there may be a number of other possible  causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the CPS equipment. But Stevenson doesn’t say.
It’s a problem that runs through the book. In a section on cars, Stevenson gives an accout of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once once again not all new locks have proved reliable. Perhaps, but maybe it’s also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors .
The game between humans and their smart devices  is complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be  way a wiser use of technology.   
If there is such a way, it should involve more than just  an awareness of the shortcomings of our machines. After all, we have lived with them for thousands  of years. They have probably been fooling us for just as long .
【小題1】
What did Paula Ceely think was the cause of her accident?           

A.Shewasnotfamiliarwiththeroad.
B.Itwasdarkandrainingheavilythen.
C.The railway works failed to give the signal.
D.Her GPS device didn’t tell her about the crossing
【小題2】
The phrase”near miss” (paragraph 2 ) can best be replaced by _______.    
A.closebitB.heavylossC.narrow escapeD.bigmistake
【小題3】
Which of the following would Rick Stevenson most probably agree with?          
A.Moderntechnologyiswhatwe can’tlivewithout.
B.Digitaltechnologyoftenfalls shortofoutexpectation.
C.Digitaldevicesaremore reliablethantheyusedtobe.
D.GPSerrorisnottheonly causeforCelery’saccident.
【小題4】
In the writer’s opinion, Stevenson’s argument is________.
A.one-sidedB.reasonableC.puzzlingD.well-based
【小題5】
What is the real concern of the writer of this article?
A.The major causes of traffic accidents and car thefts.
B.The relationship between humans and technology
C.Theshortcomingsofdigital devicesweuse.
D.Thehuman unawarenessoftechnicalproblems.

科目:高中英語 來源:2011-2012學(xué)年廣東省高三高考模擬英語試卷(解析版) 題型:閱讀理解

Outside our hotel in Ho Chi Minh City, Vietnam, a seemingly ancient woman waited beside the door with her hand outstretched. Every day I put my hand in hers as our eyes met. She never failed to return my smile, my grasp, and my greeting.

    On the last day of our visit, I found myself alone on a busy corner across the street from our hotel. Bicycles and motorbikes rushed in front of me. As I hesitated on the sidewalk, I felt a hand on my elbow and looked down to see the smile of my small beggar friend looking up at me. She nodded her head toward the street, indicating that she would take me across. Together, we moved slowly into the chaos.

    Then we moved on toward the sidewalk, where she pulled my face down to hers, kissed me on both cheeks, and then left, still smiling and waving back to me.

Traveling in poorer nations, I have witnessed a variety of ways to deal with beggars. The most common response of tourists faced with the poverty-stricken is to ignore them and focus their eyes elsewhere. I have seen people push away an outstretched hand in angry annoyance. A few may drop a few coins into the hand in a hurry, hoping that other ragged pursuers won’t immediately appear on the scene.

For many reasons, giving money is not the best response to an outstretched hand. Many world travelers have discovered that the greatest gift they can give is their time and respect. Everyone needs recognition, to be seen as worthy of being known, to feel appreciated and loved. And I believe that everyone is worthy and worth knowing.

1.The woman beggars helped the author go across the busy street because __________.

A.the author gave her material assistance

B.the author treated her kindly and friendly

C.the author would help her as a reward

D.the author was a foreigner

2.From the story, what position of the beggars in the author’s mind might be?

    A.equal                B.superior      C.lower          D.valuable

3.In common cases, people will do the following things to the beggars EXCEPT for ________.

    A.pretending to see nothing

B.handing out some money

    C.refusing them angrily

D.greeting them normally

4.According to the author, the most important things beggars really need are _________.

    A.mercy and pity  B.money and food

C.smile and greeting  D.a(chǎn)ttention and respect

5.The purpose of the passage is to _________.

    A.show how poor the beggars are in Vietnam

    B.offer some advice on dealing with begging

    C.express what we should offer the beggars

    D.describe an experience with a beggar
