AWhen Jake Olson isn‟t playing football or golf for his high school, he‟s often offering inspiration through his new book about his own life.These activities might be too much for the average 16-year-old to deal with, but Jake is blind. When people ask him how he can possibly play golf without being able to see the ball, he says he is thankful for his father‟s guidance.It seems apparent that his early experience playing sports as a person with sight and muscle memory—repeating behaviors over and over until they become second nature — have also enabled Jake to hit the ball quite well.Jake was born with a rare kind of eye cancer that took away the vision from his left eye when he was a very young child and eventually his right eye, in 2009, when he was 12 years old. Rather than letting the disease hold him back, Jake used his loss of sight and his faith as sources of motivation.“If I was going to sit on the couch all day feeling sorry for myself, I wasn‟t going to do anything. I decided r ight then and there that I wasn‟t going to let it stop me and that I was going to go out and persevere (坚持不懈),”he said.It was with that mind-set that the student from Orange Lutheran High School in California was able to write his first book, Open Your Eyes: 10 Uncommon Lessons to Discover a Happier Life. “It‟s about opening the readers‟eyes to their true potential in life and making sure that they use all the abilities that they have,” Jake said.Jake‟s father, Brian Olson, said the family is impressed w ith what he has done with his life, including showing people that they can get through hardships. “Your darkest hour can soon become your brightest, and with every setback, there‟s a setup,” Jake said. “In every one of us, there‟s more potential than we ca nA. how to become a golf masterB. how to become a successful writerC. how to cure the teenager‟s eye diseaseD. how a teenager overcome many difficulties and manage to do lots of things.2. The purpose of the book mentioned in the passage is to .A. discuss good approaches to get along with disabled peopleB. help people come up with better life goalsC. encourage people to discover and use their potential abilitiesD. explain different definitions of “a happier life”3. What can we know from the passage?A. Jake lost his right eyesight in his twelfth year.B. The vision of Jake‟s left eye was taken away in a traffic accident.C. He was blind in both eyes at the age of three.D. While Jake had a common eye disease, he lost his vision unluckily.4. What made Jake play golf without being able to see it?A. H is father‟s encouragement.B. His experience in his teenage time.C. His early experience of playing sports and the instruction of his father.D. His desire of being a golf master.BYears ago a John Hopkins professor gave a group of graduate students this task: Go to the slums(贫民窟), Take 200 boys, between the ages of 12 and 16, and investigate their background and environment, then predict their chances for the future.The students, after consulting social statistics, talking to the boys, and collecting much data,concluded that 90 percent of the boys would spend some time in prison.Twenty-five years later another group of graduate students was given the job of testing the prediction. They went back to the same area. Some of the boys -- by then men -- were still there, a few had died, some had moved away, but they came into contact with 180 of the original 200. They found that only four of the group had ever been sent to prison.Why was it that these men, who had lived in a breeding place of crime, had such a surprisingly good record? The researchers were continually told, “Well, there was a teacher…”They pressed(追问)further, and found that in 75 percent of the cases it was the same woman. The researchers went to this teacher, now living in a home for retired teachers. How had she had this remarkable influence on that group of children? Could she give them any reason why these boys should have remembered her?“No,”she said,“No,I really couldn‟t.”And then, thinking back over the years, she said musingly(沉思地), more to herself than to her questioners,“Iloved those boys…”5. How many people did the students lose touch with when they test the prediction?A. 180.B. 90.C. 20.D.75.6. According to this passage, which of the following is TRUE?A. 90 percent of the boys were sent to prison.B. Most of the boys were influenced by the teacher.C. The graduate students‟ prediction was proved to be right.D. The boys lived in an environment of no crime.7. We can learn from the last paragraph that______.A. love can create miraclesB. action speaks louder than wordsC. students should ask more questionsD. stop and think before action8. What would be the best title for this passage?A. An amazing teacherB. The s tudents‟ taskC. A surprising storyD. A remarkable interviewCDon‟t you just love ice skating every winter? Don‟t you want to impress your friends with your new trick on how to ice skate backwards with the help of these tips. Follow the steps given below and you will be able to skate backwards in no time.Stand straightThe first thing that you need to do is stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don‟t worry; this happens to all.Maintain speedNow the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling(滑浆), that is, keep pushing yourself backwards with an outwards stroke(滑动). Now bring the skate which you were using to scull, and repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.Increase your speed nowOnce you are confident that you can scull with either foot, the next thing that you have to do is increasing your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.Scull and be awareWhile you keep one foot straight, keep sculling with the other. You can do that simultaneously with both feet. Concentrate on what you are doing but don‟t see where you are doing. If you are not watching your back, you might just bang against something or someone.9. Which is the right order of ice skating backwards?a. Increasing your speed.b. Being able to stand straight.c. Trying some different tricks.d. Being able to scull with one foot.A. b-d-a-cB. c-b-d-aC. c-b-a-dD. b-a-d-c10. When you learn to maintain speed, you should .A. put most of your weight on the skate which you are scullingB. roll in a straight line with two skatesC. keep pushing yourself forward with an outwards strokeD. practise the process again and again11. The underlined word “simultaneously” in last paragraph refers to “”.A. on the contraryB. in the same wayC. at the same timeD. in the past12. What‟s the purpose of this passage?A. To explain advantages of ice skatingB. To give tips on learning ice skatingC. To introduce the history of ice skatingD. To persuade people to buy ice-skating toolsDAccording to the recent survey, one in every five fish sold was caught illegally. It threatens(威胁) food security and hurts the environment. Officials are using new observational technology to fight illegal fishing.“Thank you for taking the time to join us here in Harwell (UK) in the Operations Center to what we call …Proje ct Eyes on the Seas.‟”says Tony Long, who leads the Ending Illegal Fishing program for Pew Charitable Trusts. The group created Project Eyes on the Seas. Large three-dimensional images of a globe can be seen on a video.“It looks different from what you m ight expect because this globe only shows you the boats that are coming into this system from a live automated information system or AIS.”The screen shows 120,000 fishing boats have AIS. They are required to have the technology. But those who are fishing illegally often turn it off. The technology does not tell observers when that happens.Mr. Long says that permits researchers to understand exactly where the fishing boats are operating. The Pew team gives the information it gathers to port officials to help them decide if they should take action against a ship. Tony Long says he would like to be able to provide port officials all over the world with clear lists. They would inform the officials about ships to inspect, ships to bar from entrance, and ships to permit entrance for trade activities.The Pacific island nation of Palau was an early user of the technology. Palau has one of the richest fishing areas in the world. Last year, it announced a plan to ban commercial fishing in a 630,000 square kilometer area. K.B. Sakuma is a special adviser to the president of Palau. He says Palau is trying to deal with a recent increase in illegal, unsupervised(无人监管的)and unreported fishing.Mr. Sakuma hopes the information from the project will help Palau fight fishing piracy.13. According to the passage, what is the percentage of legal fishing?A. 20%.B. 5%.C. 40%.D.80%.14. Which of the following is TRUE according to the passage?A. When the fishermen turn off the AIS, the inspector will know the situation.B. Tony Long is in charge of the Ending Illegal Fishing program.C. Only Palau has the richest fishing areas in the world.D. Palau has solved a recent increase in illegal, unsupervised and unreported fishing.15. Where does the passage probably come from?A. Newspaper.B. Physical textbook.C. An advertisement.D. Travel magazine.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。

AWhen Jake Olson isn’t playing football or golf for his high school, he’s often offering inspiration through his new book about his own life.These activities might be too much for the average 16-year-old to deal with, but Jake is blind. When people askhim how he can possibly play golf without being able to see the ball, he says he is thankful for his father’s guidance.It seems apparent that his early experience playing sports as a person with sight and muscle memory—repeating behaviors over and over until they become second nature —have also enabled Jake to hit the ball quite well.Jake was born with a rare kind of eye cancer that took away the vision from his left eye when he was a very young child and eventually his right eye, in 2009, when he was 12 years old. Rather than letting the disease hold him back, Jake used his loss of sight and his faith as sources of motivation.‚If I was going to sit on the couch all day feeling sorry for myself, I wasn’t going to do anything. I decided r ight then and there that I wasn’t going to let it stop me and that I was going to go out and persevere (坚持不懈),‛ he said.It was with that mind-set that the student from Orange Lutheran High School in California was able to write his first book, Open Your Eyes: 10 Uncommon Lessons to Discover a Happier Life. ‚It’s about opening the readers’eyes to their true potential in life and making sure that they useall the abilities that they have,‛ Jake said.Jake’s father, Brian Olson, said the family is impressed with what he has done with his life, including showing people that they can get through hardships. ‚Your darkest hour can soon become your brightest, and with every setback, there’s a setup,‛ Jake said. ‚In every one of us, there’s more potential than we can ever imagine, and it really is a choice.‛A. how to become a golf masterB. how to become a successful writerC. how to cure the teenager’s eye diseaseD. how a teenager overcome many difficulties and manage to do lots of things.2. The purpose of the book mentioned in the passage is to .A. discuss good approaches to get along with disabled peopleB. help people come up with better life goalsC. encourage people to discover and use their potential abilitiesD. explain different definitions of ‚a happier life‛3. What can we know from the passage?A. Jake lost his right eyesight in his twelfth year.B. The vision of Jake’s left eye was taken away in a traffic accident.C. He was blind in both eyes at the age of three.D. While Jake had a common eye disease, he lost his vision unluckily.4. What made Jake play golf without being able to see it?A. H is father’s encouragement.B. His experience in his teenage time.C. His early experience of playing sports and the instruction of his father.D. His desire of being a golf master.BYears ago a John Hopkins professor gave a group of graduate students this task: Go to the slums(贫民窟), Take 200 boys, between the ages of 12 and 16, and investigate their background and environment, then predict their chances for the future.The students, after consulting social statistics, talking to the boys, and collecting much data, concluded that 90 percent of the boys would spend some time in prison.Twenty-five years later another group of graduate students was given the job of testing the prediction. They went back to the same area. Some of the boys -- by then men -- were still there, a few had died, some had moved away, but they came into contact with 180 of the original 200. They found that only four of the group had ever been sent to prison.Why was it that these men, who had lived in a breeding place of crime, had such a surprisingly good record? The researchers were continually told, ‚Well, there was a teacher…‛They pressed(追问)further, and found that in 75 percent of the cases it was the same woman. The researchers went to this teacher, now living in a home for retired teachers. How had she had this remarkable influence on that group of children? Could she give them any reason why these boys should have remembered her?‚No,‛she said,‚No,I really couldn’t.‛And then, thinking back over the years, she said musingly(沉思地), more toherself than to her questioners,‚Iloved those boys (5)How many people did the students lose touch with when they t est the prediction?A.180.B.90.C.20.D.75.6. According to this passage, which of the following is TRUE?A. 90 percent of the boys were sent to prison.B. Most of the boys were influenced by the teacher.C. The graduate students’ prediction was proved to be right.D. The boys lived in an environment of no crime.7. We can learn from the last paragraph that______.A. love can create miraclesB. action speaks louder than wordsC. students should ask more questionsD. stop and think before action8. What would be the best title for this passage?A. An amazing teacherB. The students’ taskC. A surprising storyD. Aremarkable interviewCDon’t you just love ice skating every winter? Don’t you want to impress your friends with your new trick on how to ice skate backwards with the help of these tips. Follow the steps given below and you will be able to skate backwards in no time.Stand straightThe first thing that you need to do is stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don’t worry; this happens to all.Maintain speedNow the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling (滑浆), that is, keep pushing yourself backwards with an outwards stroke(滑动). Now bring the skate which you were using to scull, and repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doingthis till you are confident enough.Increase your speed nowOnce you are confident that you can scull with either foot,the next thing that you have to do is increasing your speed.Try some of your own tricks now. Scull with either foot orwith both at the same time.Scull and be awareWhile you keep one foot straight, keep sculling with the other. You can do that simultaneously with both feet. Concentrate on what you are doing but don’t see where youare doing. If you are not watching your back, you might just bang against something or someone.9. Which is the right order of ice skating backwards?a. Increasing your speed.b. Being able to stand straight.c. Trying some different tricks.d. Being ableto scull with one foot.A. b-d-a-cB. c-b-d-aC. c-b-a-dD. b-a-d-c10. When you learn to maintain speed, you should .A. put most of your weight on the skate which you arescullingB. roll in a straight line with two skatesC. keep pushing yourself forward with an outwards strokeD. practise the process again and again11. The underlined word ‚simultaneously‛in last paragraphrefers to ‚‛.A. on the contraryB. in the same wayC. atthe same time D. in the past12. What’s the purpose of this passage?A. To explain advantages of ice skatingB.To give tips on learning ice skatingC. To introduce the history of ice skatingD. To persuade people to buy ice-skating toolsDAccording to the recent survey, one in every five fish soldwas caught illegally. It threatens(威胁) food security andhurts the environment. Officials are using new observational technology to fight illegal fishing.‚Thank you for t aking the time to join us here in Harwell (UK) in the Operations Center to what we call ‘Project Eyeson the Seas.’‛says Tony Long, who leads the Ending IllegalFishing program for Pew Charitable Trusts. The group created Project Eyes on the Seas. Large three-dimensional images of a globe can be seen on a video.‚It looks different from what you might expect because this globe only shows you the boats that are coming into this system from a live automated information system or AIS.‛The screen shows 120,000 fishing boats have AIS. They are required to have the technology. But those who are fishing illegally often turn it off. The technology does not tell observers when that happens.Mr. Long says that permits researchers to understand exactly where the fishing boats are operating. The Pew team gives the information it gathers to port officials to help them decide if they should take action against a ship. Tony Long says he would like to be able to provide port officials all over the world with clear lists. They would inform the officials about ships to inspect, ships to bar from entrance, and ships to permit entrance for trade activities.The Pacific island nation of Palau was an early user of the technology. Palau has one of the richest fishing areas in the world. Last year, it announced a plan to ban commercialfishing in a 630,000 square kilometer area. K.B. Sakuma isa special adviser to the president of Palau. He says Palauis trying to deal with a recent increase in illegal, unsupervised(无人监管的)and unreported fishing.Mr. Sakuma hopes the information from the project will help Palau fight fishing piracy.13. According to the passage, what is the percentage of legal fishing?A. 20%.B. 5%.C. 40%.D.80%.14. Which of the following is TRUE according to the passage?A. When the fishermen turn off the AIS, the inspector will know the situation.B. Tony Long is in charge of the Ending Illegal Fishing program.C. Only Palau has the richest fishing areas in the world.D. Palau has solved a recent increase in illegal, unsupervised and unreported fishing.15. Where does the passage probably come from?A. Newspaper.B. Physical textbook.C. An advertisement.D. Travel magazine.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。

第I卷阅读题甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1-3题官话与国语张鸣当今的普通话,追根溯源,跟中国最后一个王朝是满人统治,的确有那么点关系。

满人入关之前,其实很多人都会说汉语,但说的大抵是那时的东北方言。

所谓东北方言,就是融合了众多北方话形成的,很接近今天的普通话。

当然,满人也说满语,这个满语,经过努尔哈赤引入蒙文,制成满文,已经成了满人的“国语”,或者叫清语。

入主中原之后,满人统治者一度要求做官的人,无论满汉,一律要学清语,不仅识满文,而且会说满语。

就像在全国推行剃发一样,实行征服者的文化改造。

然而,清语的推广,却不了了之。

原因是满人自己,包括皇帝也不喜欢“自己的语言”。

因为这样的文字,仅仅是最高层出于政治目的生造出来的,没有多少群众基础。

这个文字里,没有传说,没有诗歌,更没有故事。

相形之下,汉语里什么都有,特别是有满人极其喜爱的《三国演义》。

在没入关之前,满人就是双语并用。

入关之后,论武力,他们是征服者,论文化,他们则是被征服者。

皇帝从小读书,就是只重汉文,不重满文,教满文的谙达,根本没有地位。

皇帝尚且如此,时间一长,别说汉臣不能说清语,就连满人大臣也不会说了。

大家都在说官话,所谓的官话,就是今天东北话和北京话的混合体。

清朝是满人当家,只能如此,进入民国,北洋政府时代也如此,定都南京的国民党政府,高层大多为南方人,还是如此,那时的国语,跟现在的普通话,基本差不多。
