玉溪一中高2014届高三下学期5月月考英语试卷总分120分，考试时间100分钟第I卷（选择题：共70分）第一部分：阅读理解（共两节，满分40分）第一节：（共15小题，每小题2分，满分30分）阅读下面的短文，从每题所给的四个选项（ABCD）中，选出最佳选项。
AAs a boy，Tim was much influenced by books about the sea，but in fact by the age of fifteen he had decided to become a doctor rather than a sailor．His father was a dentist and as a result, Tim had the opportunity of meeting many doctors either at home or elsewhere．When he was fourteen he was already hanging around the clinic of a local doctor where he was supposed to be helping to wrap up medicine bottles，but was actually trying to listen to the conversations taking place between the doctor and his patients in the next room．During the war Tim served in the Navy as a surgeon(外科医生)．“That wa s the happiest time of my life. I was dealing with very real suffering and on the whole making a success of it．”In California he taught the country people simple facts about medicine．He saw himself as a life-saver．He had proved his skills to himself and his ability to make decisions．Thus，while he was able to tell them what to do，he could feel he was serving them．After the war，he got married and chose to be a doctor in the countryside，working under an old doctor who was popular in the area，but who hated the sight of blood and believed that the secret of medicine was faith．This gave the young man many opportunities to go on working as a life-saver．1．Tim decided to become a doctor at fifteen mainly because．A．his father wanted him to be soB．his father was a surgeon himselfC．he had read many books about medicineD．he had chances to know about doctors through his father2．Which of the following is true according to the passage？A．Tim got married to the old doctor's daughter．B．Tim continued working as a surgeon after the war．C．Before the war，Tim worked as a doctor at a local clinicD．While working in California, Tim taught life-saving to the patients．3．From the passage we can infer that TimA．was sent to Europe during the war.B．worked as a surgeon during the war.C．was not afraid of seeing blood.D．decided to give up medicine for faith.B“Tear them apart！”“Kill the fool！”“Murder the referee(裁判)！”These are common remarks one may hear at various sporting events．At the time they are made，they may seem innocent enough．But let's not kid ourselves．They have been known to influence behavior in such a way as to lead to real violence．Books have been written about the way words affect us．It has been shown that words having certain meanings may cause us to react in ways quite foreign to what we consider to be our usual behavior．I see the term “opponent”as one of those words．Perhaps the time has come to delete it from sports terms．The dictionary meaning of the term “opponent” is “enemy”，or “one who opposes your interests．”Thus，when a player meets an opponent，he or she may tend to treat that opponent as an enemy，I remember an incident in a handball game when a referee refused a player's request for a time out for a glove change because he did not consider them wet enough．The player went away to rub(摩擦)his gloves across his wet T-shirt and then screamed “Are they wet enough now?”In the heat of battle，players have been observed to throw themselves across the court without considering the effect that such a move might have on anyone in their way．I have also witnessed a player reacting to his opponent's intentional and illegal blocking by hitting him with the ball as hard as he could during the course of play．Off the court，they are good friends．Does that make any sense？It certainly gives proof of a court attitude which differs from normal behavior． Therefore，I believe it is time we elevated(提升)the game to the level where it belongs setting an example to the rest of the sporting world. Replacing the term “opponent” with “associate” could be a good way to start．The dictionary meaning of the term “associate”is “friend”or “companion．”You may soon see and possibly feel the difference in your reaction to the term “associate” rather than “opponent”．4．What did the handball player do when be was not allowed to change his gloves？ A．He refused to continue the game．B．He angrily hit the referee with a ball．C．He insisted that the referee was unfair．D．He wet his gloves by rubbing them across his T-shirt．5．According to the passage，players in a game may．A．throw the ball illegally at the opponent blocking their wayB．keep on screaming and shouting throughout the gameC．1ie down on the ground as an act of protectionD．kick the ball across the court with force6．What is the fourth paragraph mainly about？A．The player's eagerness to winB．The player's bad behaviorC．The player's attitudes towards the game．D．The player's totally different behavior on and off the court7．What can be concluded from the passage？A．Players should be educated to respect referees on the court．B．Replacing the present terms on the court can help reduce violence．C．Raising the referee's sense of responsibility can help reduce violence． D．Changing the attitude of players on the sports field can help reduce violence．CWhen we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are near-sighted can only see things that are very close to their eyes, and everything else seems blurry (=unclear). Many people who do a lot of work, such as writing, reading and sewing become near—sighted.People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the objec t’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.8. When things far away seem indistinct(模糊不清) , one is probably____.A. near-sightedB. far-sightedC. astigmaticD. suffering from cataracts9. We may read this passage on the _________ column of a newspaperA. fashionB. guidebookC. biologyD. science10. Having two eyes instead of one is particularly useful for______.A. seeing at nightB. seeing objects far awayC. looking over a wide areaD. judging distances11. People who suffer from astigmatism have______.A. one eye bigger than the otherB. eyes that are not exactly the right shapeC. a difficulty that can be corrected by an operationD. an eye difficulty that cannot be corrected by glassesDIt is common and usual to see people freak out when they face challenges in their life. We all pass in different life problems and challenges. No one is free of life problems. Only a dead man faces no problem. As long as you are alive, challenges are everywhere.How do you face problems and challenges in your life? Problems and challenges are the building blocks of your personality. They make you who you are. Besides, whether what happened in your life builds or destructs you depends on how you look at it. If you take your problems as troubles, they will be troubles and may cause destruction. If you take them as constructive tools, you are going to be built up on them.Problems are everywhere. No one can avoid them. And they are good too. They open up a different look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as well as bad sides. Focus on the good one. Look at the bright side.Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right beside you who can turn everything into your best if you are willing to turn to them. No matter what happens, they will be there to help you. Trust them and they will never let you down. All you need to know is that you are loved wherever you are.12. What’s the meaning of the underlined phrase “freak out” in Paragraph 1?A. Feel shy.B. Stay calm.C. Keep up.D. Feel upset.13. In Paragraph 2, the writer implies that ______.A. problems cause troublesB. attitude is everythingC. challenges can be avoidedD. personalities are built on failures14. According to the last paragraph, when we’re in trouble, we ______.A. can only depend on our parentsB. are not aloneC. should only believe ourselvesD. are not confident15. What’s the writer’s purpose to write the passage?A. To encourage.B. To compare.C. To prove.D. To explain.第二节（共5小题，每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
