At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious(明显的) to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, don't worry about them. Just continue as if nothing happened.Even if you do make an obvious mistake during a speech, that doesn't really matter. If you have ever listened to Martin Luther King's famous speech---"I have a Dream", you may notice that he stumbles(结巴) over his words twice during the speech. Most likely, however, you don't remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making.People care a lot about making a mistake in a speech because they regard speech-making as a kind of performance rather than as an act of communication(交流). They feel the listeners are like judges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performer. They are looking for a well-thought-out speech that expresses the speaker's ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker's attractiveness by making him more human.As you work on your speech, don't worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.25. The underlined part in the first paragraph means that no one will ______.A. be smarter than youB. notice your mistakesC. do better than youD. know what you are talking about26. You don't remember obvious mistakes in a speech because ______.A. your attention is on the contentB. you don't fully understand the speechC. you don't know what the speaker plans to sayD. you find the way of speech-making more important27. It can be inferred from the passage that ______.A. giving a speech is like giving a performanceB. one or two mistakes in a speech may not be badC. the listeners should pay more attention to how a speech is madeD. the more mistakes a speaker makes, the more attractive he will be.28. What would be the best title for the passage?A. How to Be a Perfect SpeakerB. How to Make a Perfect SpeechC. Don't Expect a Perfect SpeechD. Don't Expect Mistakes in a SpeechCThe Indian government may use 3D paintings as virtual speed breakers（减速带）on major highways and roads, in order to check speeding and careless driving, and finally make its deadly roads a little safer. "We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers," India's transport minister Nitin Gadkari wrote.The optical illusions(视觉错觉) are supposed to encourage drivers to slow down automatically. Earlier, India had ordered the removal of all speed breakers from highways, which are considered to be a safety hazard for high-speed vehicles. India has the highest number of road accident deaths in the world. According to the World Health Organisation, over 200,000 people are killed by road accidents.The use of optical illusions as speed breakers was first pioneered in the American city of Philadelphia in 2008, as part of a campaign against speeding motorists. The technique has also been tried out in China to create floating 3D crossings. In India, cities such as Ahmedabad and Chennai have already experimented with 3D zebra crossings in the last one year. In Ahmedabad for instance, a mother and her daughter, both artists, have painted 3D crosswalks in the first few months of 2016. The artists say their motto is "to increase the attention of drivers", and that the concept has been successfully tested in accident-prone zones on a highway.However, critics argue that once drivers know that these speed breakers are visual illusions, they may ignore them. Others also point out that India's decision does not consider the safety of a large number of pedestrians. In the end, the new policy may be just one step towards improving road safety.29. Why are 3D paintings used on main highways and roads?A.To make the surroundings more beautiful.B.To attract the attention of tourists.C.To reduce the rate of traffic accidents.D.To show the advanced technology.30. Which of the following words is closest to the meaning of “hazard” in paragraph 2?A.ReminderB.ThreatC.RegulationD.Theory31. What can we learn from Paragraph 3 and 4?A.Philadelphia, the U.S.A is th second place to use virtual speed breakers in theworld.B.The idea tested in Ahmedabad recently has been a failure.C.The new policy of 3D zebra crossings must be carried out smoothly.D.The use of optical illusions as speed breakers is controversial in India.32. What do we know about 3D zebra crossings from the passage?A.They can vastly lower the death rate in India.B.They have been widely used in India so far.C.They are designed to increase drivers’ attention.D.They are welcomed by both drivers and pedestrians.DI used to believe courtesy was a thing of the past. Very seldom have I encountereda courteous human being in this modern era.Recently, I had to change my thinking, when I came face to face with just such a human being in a coffee place, with my two daughters. The place was crowded as usual and we had to climb steep stairs in order to find an empty table. After enjoying coffee and snacks, we went down the narrow stairs, where there was hardly any space for another person to either climb up or come down.Just as I was in the middle of the stairs, a gentleman entered the main entrance of the restaurant which was right in front of the staircase. I was sure I would be pushed roughly by this man going up. I kept coming down as fast as I could. My daughters were already down, looking up at me worriedly, hoping I would reach them before the stranger started walking up the stairs, knowing I was a nervous sort.Nearly reaching them, I noticed the man still standing near the door. I reached my daughters and passed the stranger at the entrance door which he kept holding open. I looked back thinking he was still at the door, deciding whether to go in or find another less crowded place. I saw him going up the stairs, two at a time. I told my daughters about it and all three of us felt bad that we did not even thank the courteous gentleman who was actually holding the door open for us ladies to pass through before going up.Such well mannered people are hard to find these days, when pushing is very common in our advanced but aggressive society. We applauded for his chivalry(骑士精神).33. What did the author think of the man at the first sight of him?A. He was in a hurry.B. He would wait for her.C. He would cross her rudely.D. He was a man with good manners.34. Why did the author’s daughters worry about her?A. She was too old to walk fast.B. She was easy to be disturbed.C. She took up too much space.D. She focused too much on the man.35. What can we learn about the man from Paragraph 4?A. He might be a waiter of the café.B. He might have an urgent business to do.C. He fell in love with one of the author’s daughters.D. He would hold the door open for all.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。

辽宁省朝阳市三校协作体2017-2018学年高三一模考试英语试卷（带解析）一、阅读理解（共4小题）1.When Armida Armato’s daughter, Alexia, came home from school one day last year keen to go on a school trip to Ecuador, she wasn’t too sure how to feel. She was happy that her daughter could experience something she never did as a teen but was fearful of letting her travel to such a remote part of the world.Alexia was 16 at the time, a student at Westwood High School. The school sponsored a humanitarian trip for 26 students and two teachers to spend 18 days living in a mountain village to build a one-room school. Even though Armato trusted her daughter, the other students and the teachers, she was worried about the side effects from the travel vaccines, possible accidents, and medical care.Now th at Alexia was home, Armato said she saw her daughter’s new maturity, greater confidence and independence. “This is the best thing I ever did,” Alexia said. “The experience was so eye-opening and life-changing. You’re with people who are not as lucky as you are. They live in very poor conditions but they’re so happy and outgoing. You say, ‘My God. I’m taking everything for granted back home.’”She said they built a one-room school from scratch with no mechanical cement mixers. They used their hands, shovels and basic tools. She and another student lived with a local family in a small village about eight hours outside the capital, Quito. Despite the initial strangeness and knowing only basic Spanish, she said they grew very close and felt like a family.Every year, groups of students at Montreal High School like Alexia pack their bags and fly off with classmates and teachers to developing countries where they volunteer for a variety of projects.“Armato’s worries are very common among parents,” says Bill Nevin, a teacher at St. George’s High School. He organizes a humanitarian rip to India to the Sheela Bal Bhavan orphanage and says the three biggest fears families have are health, security and contact. 1．When hearing the news that her daughter would go on a school trip to Ecuador, Armato was _______.A．proud and happyB．supportive but concernedC．fearful and nervousD．excited but puzzled2．The underlined phrase “from scratch” in Paragraph 4 probably means “______”.A．having great helpB．using high technologyC．ending up in failureD．starting from the beginning3．What would be the best title for the text?A．V olunteering helps students grow and develop.B．School trips make parents worried about their children.C．Ecuador is the most attractive travel destination in the world.D．Brave Alexia dreams to work in Ecuador one day.2.Homestay UK/Great BritainHere you will find a selection of homestay hosts and host families in the UK．If you want to learn more about the British host family of your choice, please click on information at www．Homestaybooking．Com．You will then see a personal introduction of the UK homestay host．If you don’t want to search yourself, just register for free and receive our matching recommendations．Chika and Tara from London, the United KingdomInformation about the homestay hostChika is 28 years old．She is away from home most of the time．Tara is 18 years old．She is at home every day．They both speak English．Chika and Tara’s guests can stay for at least 5 ni ghts and up to a maximum of 365 nights．Chika and Tara have no children living at home．It is a non-smoking residence(住宅)．No pets live in this household．Information about the homestay accommodationThe accommodation is in London．The name of the neighborhood is Greenwich．The distance to the city center is 1．6km．The next access point to public transport is at 15 m distance．Three guests can stay in Tara and Chika’s house at the same time．The following accommodation is generally available:Single room with shared use of the family bathroom*Size: 12．0 ㎡*Facilities: desk, Internet access, mirror, hairdryer and wardrobe(衣橱)*Price per night per person: ￡20．00 per night(one single)Twin room with shared use of the family bathroom*Size: 15．0 ㎡*Facilities: TV, desk, Internet access, mirror, hairdryer and wordrobe*Price per night per person:￡20．00 per night(one guest)￡17．00 per night(two guests)The room charge includes the following services: Internet access, regular room cleaning, breakfast, free use of the washing machine．Additional available service at an extra charge: Pick-up service(￡60．00 one-way);

Let’s face it．Thinking our life is good enough doesn’t come naturally to many people．When we have high expectations of everything in life we will run into disappointment．Only when we are aware that needs are different from desires can we live with satisfaction．Here are a few ideas to help you be happier with what you have and who you are．Focus on what you are thankful for．Most people want things to be better than they are, or when things are going well, we forget to appreciate what we have．Learn to reflect on how much better things are than they could be．Focus on what you are thankful for．Write down 5 things you are grateful for right now．When we hold onto regrets from decisions we have made, it can really poison our well-being．Many people regret something they can no longer change, which ends up holding them back from moving forward in a more positive manner．What happened in the past is done and gone, so work to stay present and be mindful of the current moment to find more joy and fulfillment．When we use other people as the measuring stick for our personal success and quality of life we are likely to be less satisfied．Social comparisons can provide useful information when we try to learn from others, but they also hold our perspective in a discontented position．Compare yourself less with others so you can be satisfied more．When you are focused on your big ambitions and future goals you might elide the daily pleasures that surround you．Learn to slow down and absorb the wonder and beauty around you．Stay present and focus on the task you’re undertaking at the moment．Don’t let the life pass you by because you’re always on the go and distracted by ambition．Practice looking at life through the lens of contentment and it will become more natural．1．How can we live with contentment?A．To change our lifestyle．B．To have a motivation in life．C．To give less attention to what we are grateful for．D．To realize the difference between needs and desires．2．What’s the main idea of Paragraph 3?A．Make wise decisionsB．Know the present situationC．Let go of regretsD．Remember the past3．The underlined word “elide”(in Paragraph 5) probably means “______”．A．enjoy B．change C．create D．neglect4．What should you do to put yourself in a good mood?A．Make time for simple pleasures．B．Learn from successful people．C．Focus on your future goals．D．Create chance to learn more．二、信息匹配（共1小题）5.Mary is digging in the ground for a photo, when along comes John．Seeing that there is no one in sight, John starts to scream．John’s angry mother rushes over and drives Mary away．Once his m um has gone, John helps himself to Mary’s potato．We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him．But Mary and John are not humans．They’re African baboons(狒狒)．___1___John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later seen playing the same tricks on others．___2___Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated．___3___ An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting．When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day．”Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal．A zoo worker describes how an ape dealt with an enemy．“He slowly stole up behind the other ape, walking on tiptoe．When he got close to his enemy, he pushed him violently in the back, then ran indoors．” Wild apes do not normally walk on tiptoe．____4___ But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying．It seems that trickery does play an important part in ape societies．____5___ Studying the intelligence of our closest relative could be the way to understand the development of human intelligence．A．In most cases the animal probably doesn’t know it is cheating．B．An amusing example of this comes from a psychologist working in Tanzania．C．And playing tricks is as much a part of monkey behavior as it is of human behavior．D．So the psychologists asked his colleagues if they had noticed this kind of trickery．E．The ability of animals to cheat may be a better measure of their intelligence than their use of toolsF．This use of a third individual to achieve a goal is only one of the many tricks commonly used by baboons．G．Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why．三、完形填空（共1小题）6.I am a mom of two young children whom we home-school．This 1 that they are with me almost constantly．Whenever possible I will 2 random acts of kindness;

Personally, I think the reform has between advantages and disadvantages．O n the one hand, it can reduce students’ learn burden and enable English to return back to its true function．On the other hand, it will cause students to spend less time on studying English and to attached less importance to English．If so, students will not have a good knowledge of English．What’s more, if students don’t have so a good ability, they will not be able to broaden our horizon and meet the future challenges．六、书面表达（共1小题）9.假设你是李华，你的英国笔友Bob将于九月到你所在城市的建新华文学校学中文，来信请你在学校附近为他找一套住房。

At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious(明显的) to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, don't worry about them. Just continue as if nothing happened.Even if you do make an obvious mistake during a speech, that doesn't really matter. If you have ever listened to Martin Luther King's famous speech---"I have a Dream", you may notice that he stumbles(结巴) over his words twice during the speech. Most likely, however, you don't remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making.People care a lot about making a mistake in a speech because they regard speech-making as a kind of performance rather than as an act of communication(交流). They feel the listeners are like judges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performer. They are looking for a well-thought-out speech that expresses the speaker's ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker's attractiveness by making him more human.As you work on your speech, don't worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.25. The underlined part in the first paragraph means that no one will ______.A. be smarter than youB. notice your mistakesC. do better than youD. know what you are talking about26. You don't remember obvious mistakes in a speech because ______.A. your attention is on the contentB. you don't fully understand the speechC. you don't know what the speaker plans to sayD. you find the way of speech-making more important27. It can be inferred from the passage that ______.A. giving a speech is like giving a performanceB. one or two mistakes in a speech may not be badC. the listeners should pay more attention to how a speech is madeD. the more mistakes a speaker makes, the more attractive he will be.28. What would be the best title for the passage?A. How to Be a Perfect SpeakerB. How to Make a Perfect SpeechC. Don't Expect a Perfect SpeechD. Don't Expect Mistakes in a SpeechCThe Indian government may use 3D paintings as virtual speed breakers（减速带）on major highways and roads, in order to check speeding and careless driving, and finally make its deadly roads a little safer. "We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers," India's transport minister Nitin Gadkari wrote.The optical illusions(视觉错觉) are supposed to encourage drivers to slow down automatically. Earlier, India had ordered the removal of all speed breakers from highways, which are considered to be a safety hazard for high-speed vehicles. India has the highest number of road accident deaths in the world. According to the World Health Organisation, over 200,000 people are killed by road accidents.The use of optical illusions as speed breakers was first pioneered in the American city of Philadelphia in 2008, as part of a campaign against speeding motorists. The technique has also been tried out in China to create floating 3D crossings. In India, cities such as Ahmedabad and Chennai have already experimented with 3D zebra crossings in the last one year. In Ahmedabad for instance, a mother and her daughter, both artists, have painted 3D crosswalks in the first few months of 2016. The artists say their motto is "to increase the attention of drivers", and that the concept has been successfully tested in accident-prone zones on a highway.However, critics argue that once drivers know that these speed breakers are visual illusions, they may ignore them. Others also point out that India's decision does not consider the safety of a large number of pedestrians. In the end, the new policy may be just one step towards improving road safety.29. Why are 3D paintings used on main highways and roads?A.To make the surroundings more beautiful.B.To attract the attention of tourists.C.To reduce the rate of traffic accidents.D.To show the advanced technology.30. Which of the following words is closest t o the meaning of “hazard” in paragraph 2?A.ReminderB.ThreatC.RegulationD.Theory31. What can we learn from Paragraph 3 and 4?A.Philadelphia, the U.S.A is th second place to use virtual speed breakers in theworld.B.The idea tested in Ahmedabad recently has been a failure.C.The new policy of 3D zebra crossings must be carried out smoothly.D.The use of optical illusions as speed breakers is controversial in India.32. What do we know about 3D zebra crossings from the passage?A.They can vastly lower the death rate in India.B.They have been widely used in India so far.C.They are designed to increase drivers’ attention.D.They are welcomed by both drivers and pedestrians.DI used to believe courtesy was a thing of the past. Very seldom have I encountereda courteous human being in this modern era.Recently, I had to change my thinking, when I came face to face with just such a human being in a coffee place, with my two daughters. The place was crowded as usual and we had to climb steep stairs in order to find an empty table. After enjoying coffee and snacks, we went down the narrow stairs, where there was hardly any space for another person to either climb up or come down.Just as I was in the middle of the stairs, a gentleman entered the main entrance of the restaurant which was right in front of the staircase. I was sure I would be pushed roughly by this man going up. I kept coming down as fast as I could. My daughters were already down, looking up at me worriedly, hoping I would reach them before the stranger started walking up the stairs, knowing I was a nervous sort.Nearly reaching them, I noticed the man still standing near the door. I reached my daughters and passed the stranger at the entrance door which he kept holding open. I looked back thinking he was still at the door, deciding whether to go in or find another less crowded place. I saw him going up the stairs, two at a time. I told my daughters about it and all three of us felt bad that we did not even thank the courteous gentleman who was actually holding the door open for us ladies to pass through before going up.Such well mannered people are hard to find these days, when pushing is very common in our advanced but aggressive society. We applauded for his chivalry(骑士精神).33. What did the author think of the man at the first sight of him?A. He was in a hurry.B. He would wait for her.C. He would cross her rudely.D. He was a man with good manners.34. Why did the author’s daug hters worry about her?A. She was too old to walk fast.B. She was easy to be disturbed.C. She took up too much space.D. She focused too much on the man.35. What can we learn about the man from Paragraph 4?A. He might be a waiter of the café.B. He might have an urgent business to do.C. He fell in love with one of the author’s daughters.D. He would hold the door open for all.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。

AFor a long time being happy was considered something that just happened, and there was nothing special about it. Now we know that getting along with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything from our friends. Another way is to look for good points, not bad ones in other people. It is surprising how successful this treasure hunt can be.You don’t have to be spineless(没有骨气的) in order to be popular. In fact, you will be liked and respected if you are not afraid to stand up for your rights. But do it politely and pleasantly. Being friendly and polite to your group, to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character.You can not expect to be perfect, and you must learn not to be unhappy when you make mistakes. Everyone makes mistakes, and no one is to be blamed unless he refuses to learn from them. Many young people become discouraged when they know in themselves qualities that they do not like—selfishness, laziness, and other unpleasant qualities. Just remember that we all have some of these faults and have to fight against them.At the same time, it is important to remember that, while you are probably no worse than others, the best way to be happy is to think yourself above other people. When something is wrong, it is good sense to try to make it right. Perhaps you don’t like a teacher or a classmate. Try to see why and look at yourself, too, to be sure that you are not doing anything to make that person dislike you. Some day, things may turn out all right and then you will have to learn to get along the best with situation, without thinking too much about it. Worrying never helps in a situation you can’t change.21. According to the passage, if one wants to be popular he has to _____.A. be polite and friendlyB. give up some rightsC. avoid arguing with other peopleD. be ready to change his or her character22.The passage shows that there is no perfect person but everyone should be blamed if he _____.A. is no better than othersB. is selfish and lazyC. does not draw a lesson from his own faultD. is very happy about his unpleasant quality23.The passage implies that in order to be a happy person, one should consider oneself _____.A. no better than othersB. not the same as othersC. as having something better than othersD. as having better chances than others24.The purpose for the writer to write the passage is to _____.A. train you to be perfectB. show you the way to be happyC. tell you how to act when you dislike a personD. teach you how to be popular among your friendsBDo you want to go out of town for a bit of rest and relaxation?

Is teamwork out of date？Why is it so hard to effectively conduct teamwork in those days?One way we employ teamwork in everyday lives is by becoming a parent. It is parents’ job to teach their children the basic skills and give them the knowledge they need to be successful in life. This，to me，requires teamwork. For example，the mother teaches her children manners and good health skills，while the father teaches them how to catch a ball or drive a car. However，in today’s society，we find that more and more parents are feeling that this teamwork is a one­sided thing. According to a report，there are 13.7 million single parents raising their children in the US and this could be due to the fact that parents don’t take responsibility for their children，so they leave one parent to do it alone. This is a sad fact，and it reflects that effective teamwork is losing ground in the parenting aspect of our everyday lives.Another place where teamwork affects us greatly is in our jobs. It doesn’t matter if you have a small company or a large company：if you have at least one employee and yourself，then teamwork works. I have noticed that with the current economic recession(衰退)，people are racing to grab jobs but the quality of people’s work has gone down greatly. It just appears to me that people do not take pride in their work any more. They get to work as fast as they can，just to receive the paycheck，but their quality standards fly right out of the windows. So I think teamwork is losing ground in the workforce.As you can see，we run into the aspects of teamwork in just about everything we do. Do you believe teamwork is really losing ground in today’s society？I think it is.28．Why does teamwork disappear in the parenting aspect of our daily life?A．Parents have no time to spare for their children.B．Parents have no chances to teach their children about it.C．Many children are often brought up by a single parent.D．Many children are independent to deal with their matters.29．Teamwork is losing ground in the workforce mainly because .A．workers don’t like to work together with othersB．workers’ sense is affected by economic recessionC．workers want to prove they are more capableD．fewer workers are employed to save money30．The author wants us to believe his opinion by .A．listing some dataB．giving some examplesC．asking some questionsD．analyzing some cases31．The underlined phrase “fly right out of the windows” in Paragraph 3 means “”．A．disappear B．Improve C．increase D．matterDAround four years ago，I received a call from the principal of our school as to the “Parents View” talk the next morning. He asked me to speak to the group. After the call，my whole body became feverish and panicky. The time from his call to the next morning seemed like years. The whole night，I could not sleep with many ominous apprehensions in mind. One of them was to call the principal with regret and tell him that I could not come. Finally，I gathered some courage. I thought，“If I miss this opportunity，surely the school will never invite me again to any of their programs.”I reached the school in time. Before my turn came，my whole body was trembling. When my turn came and I started speaking，my heartbeat increased and my mouth went dry. I wasn’t even able to read the written speech properly. I was not aware of where I was standing and what I was reading. That was the day when I realized my biggest weakness：Public Speaking.After my speech，I met with the principal and explained what happened to me. He told me that this happens to everyone. Even great speakers faced the same things when they started. He suggested that I come again next time.Around one month later，I was invited to refer to a topic on motivation. This time I was feeling comfortable. My speech was appreciated by the principal as well as the teachers，because I was able to get my idea across to them. They encouraged me and praised my efforts.After delivering it successfully，I became more confident. I said to myself，“If I can speak in front of such a learned audience，like the principal who educates others，I can now speak in front of others too.”I started delivering lectures on various topics like Self Motivation，Personality Development，Personal Excellence，Spoken English and Presentation Skills. This has become a passion for me. I have learned that everything is possible if we have the courage to take the first step. 32．Which of the following is the best title for the passage?A．Practice Makes a Man a Better SpeechmakerB．Public Speaking Makes a Man EmbarrassedC．Principals Provide the Best ChancesD．Spoken English Develops in Making Speeches33．The author had bad feelings before the speech because .A．he disliked the idea of giving a lectureB．he had got a high fever before thatC．he regretted accepting the invitationD．he feared he couldn’t perform it properly34．What does the underlined part “ominous apprehensions” in the first paragraph mean?A．Unlucky opportunities. B．Negative ideas.C．Curious views. D．Happy comments.35．What can we conclude from the passage?A．Nothing is to be got without pains but poverty.B．Knowledge makes humble；ignorance makes proud.C．A journey of a thousand miles begins with a single step.D．Necessity is the mother of invention.第二节；（共5小题；每题2分，总分值10分）依照短文内容，从短文后的选项当选出能填入空白处的最正确选项，选项中有两项是多余项。
