世迅早Blondin was a very famous acrobat(杂技师) in the 19th century. He used to walk on a tight--rope across the Niagara Falls(瀑布). On September 8th, 1860, a crowd of about 300,000 people gathered at Niagara to watch Blondin carry a man across! Three men had offered to go with him, but they falled to appear, so Blondin asked his manager, Mr. Colcord, to climb on his back, Colcord agreed to go this so as not to disappoint the crowd, but he was terrified. The crossing was very difficult because Colcord was heavier than Blondin thought. After he had gone a short way, Blondin had to stop in order to rest. He asked Colcord to get down. At first Colcord refused, but at last he had to. He clung to (紧紧握住) Blondin’s leg and the rope in order not to fall, Blondin had to stop six times during the crossing so as to rest.

I’m a Chinese student studying in Canada. I have been a boarder(寄宿生) with the Carsons for more than a year and a half.
The Carsons live in their own house, which has four bedrooms including the one in the basement(底层) which I live in. Judy does all the work in the house and Andrew is responsible for the work in the garden. When they go out in they evening, they often ask me to look after their children.
Judy’s parents, Mr. and Mrs. Morris, lived in another city. Judy was their only child and naturally they doted on(溺爱) Judy’s children. They often sent the children presents.
Last April Mr. Morris died. Now that Mrs. Morris was quite alone, I expected that Judy would want her to come and live with them. One day, Margaret told me grandma was coming to live with them and her daddy and mummy would want my room back. The news didn’t surprise me and the next day I went to Judy and asked her about it. I said I couldn’t think of living in their basement room any longer if it was needed for Mrs. Morris. Judy seemed surprised at first. Then she told me there was no deed for me to move, for they hadn’t yet come to any decision about her mother coming to live with them. “Naturally I’m worried about my mother. She has been in poor health.” She smiled sadly and added. “To be honest, Andrew and my mother have never got on well. We’ll wait a bit and see what happens. Perhaps Moter will be all right living herself, of perhaps they will both change their minds.”
That was six months ago. During this time I’ve heard that Mrs. Morris has had two illnesses and that her health has got worse. A nursing home was mentioned once but Mrs. Morris refused to go there. So up to now she’s still living alone and I’m still living in the basement room.
1. What is the relationship between the speaker and the Carsons?
A. He is a brother of Andrew Carson.
B. He is a close friend of the Carsons.
C. He is a student of Judy Carson.
D. He is a student who pays to live and have meals at the Carsons’ house.
2. Why did the speaker expect Mrs. Morris to come to live with her daughter?
A. Because Mr. Morris was dead.

C. Because Mrs. Morris lived all by herself.
D. Because of all the reasons mentioned in A, B and C.
3. Which of the following statements is NOT true according to the passage?
A. Mrs. Morris was coming to live with the Carsons, so they asked the speaker to move.
B. Judy had no brothers or sisters to look after her mother.
C. Mrs. Morris loved her grandchildren very much.
D. The Carsons once suggested that Mrs. Morris go to live in a nursing home.
4. Why didn’t Mrs. Morris come to live with her daughter’s family?
A. Because the speaker lived in the basement room and there was no other room for her to live in.

In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The ―spider story‖ is often told. Robert Bruce, leader of the Scots in the 13th century, was hiding in a cave from the English. He watched a spider spinning a web(蜘蛛织网). The spider tried to reach across a rough place in the rock. He tried six times without success. On the seventh time he made it and went on to spin his web. Bruce is said to have taken heart and to have gone on to defeat the English„ Edison, the inventor of the light bulb, made hundreds of models that failed before he found the right way to make one.
So what? First, always think about your failure. What caused it? Were conditions right? Were you in top from yourself? What can you change so things will go right next time?
Second, is the goal(目标)you're trying to reach the right one? Try to do some thinking about what your real goals may be. Think about his question, “If I do succeed in this, where will it get me?”伍渣祥腔搏This may help you prevent failure in things you shouldn't be doing anyway.

2017高考英语真题分类汇编阅读理解真题及答案二
In sport the sexes(性别)are separate. Women and men do not run or swim in the same races. Women are less strong than men. That at least is what people say. Women are called the weaker sex, or, if men want to please them, the fair sex. But boys and girls are taught together at schools and universities. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men . A European woman can expect to live until the age of 74, a man only until he is 68.Are women's bodies really weaker?

Conditions are very different now and sport is much more serious. It is so serious that some women athletes are given hormone (荷尔蒙)injections(注射).

2017高考英语真题分类汇编阅读理解真题及答案三
People bury treasure to stop other people from taking it. They choose a quiet place, dig a deep hole and bury the treasure in it. Then they make a map of where the treasure is or write down other clues(线索)that will help them or someone else to find it again.
In Britain a few years ago; a writer wrote about some treasure that he had buried. He put clues in the story to help readers find it. Thousands of people hunted for the treasure. They dug holes all over Britain, hoping to find it.
One of the most popular adventure stories ever written is Robert Louis Stephenson's ‗Treasured Island‘, an exciting story about a young boy, Jim Hawkins, who is captured by pirates and later finds some buried treasure.
Then there is the true story about a man who had to travel overseas for a year. He did not trust banks, so he buried his life savings in a park. Then he went away. On his return, he went straight to the park. But the park was no longer there. In its place there was a huge building.
And then there was the man who buried his savings, all in bank notes, in a waterproof(防水的) bag. When he dug it up years later, there was nothing left. Worms and insects had eaten the bag and everything in it.
And of course, these are stories about people who bury things and either forget where they have buried them or lose the map.
Although it is true that people sometimes lose their money because a bank fails, banks are still the safest place to keep our savings and treasures.
1.People who bury treasure usually
A.do not trust banks
B.have a little money .
C.want to live in a quiet place.
D.expect to lose it
2.The writer in Britain

3.―Treasure Island‖
A.is a story about pirates.
B.is about the adventures of Jim Hawkins.
C.is the most popular story ever written
D.is a well-known fairy tale.
4.The man who buried his money in a park
A.thought his money was safer there than in a bank.
B.travelled on the sea for a year.
C.got his life savings back again.
D.stayed away longer than he expected.

When it was brought, the nobleman took a spoonful, but the soup was so hot that he burned his mouth and tears came to his eyes, The merchant asked him why he was weeping. The nobleman was ashamed to admit (承认) that he had burned his mouth and answered, “Sir, I once had a brother who committed a great crime (犯罪), for which he was hanged. I was thinking of his death, and that made me weep.” The merchant believed this story and began to eat his soup. He too burned his mouth, so that he had tears in his eyes.

In a very real sense, people who have read good literature have lived more than people who cannot or will not read. To have read Gulliver’s Travels is to have had the experience of listening to Jonathan Swift, of learning about man’s inhumanity (残酷) to man. To read Huckleberry Finn is to feel what it is like to drift (漂流) down the Mississippi River on a raft (木排). To have read Byron is to have suffered his rebellions with him and to have enjoyed his nose—thumbing at (对……的蔑视) society. To have read Native Son is to know how it feels to be frustrated (受挫折) in the particular way in which Blacks in Chicago are frustrated. This is effective communication (交流). It enables us to feel how others felt about life, even if they lived thousands of miles away and centuries age. It is not true that “We have only one life to live.” If we read, we can live as many more lives and as many kinds of lives as we wish.
1. The sentence “People who have read good literature have lived more than people who cannot or will not read” suggests that ______.

高考英语阅读理解题【3】
When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation (住所). I suggested that they should stay at ‘bed and breakfast’ houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.
“We didn’t stay at bed and breakfast houses,” they said, “because we found that most families were away on holiday.”
I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought ‘VACANCIES’ meant ‘holidays’, because the Spanish word for ‘holidays” is ‘vacaciones’. So they did not go to house where the sign outside said ‘VACANCLES’, which in English means there are free rooms. Then my friends went to house where the sign said ‘NO VACANCLES’, because they thought this meant the people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels!
We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word ‘DIVERSION’ means fun. In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word ‘DIVERSION’ on a road sign, they thought they were going to have fun. Instead, the road ended in a large hold.
English people have problems too when they learn foreign languages. Once in Paris. when someone offered me some more. coffee, I said ‘Thank you’ in French. I meant that I would like some more, However , to my surprise the coffee pot was taken away! Later I found out that ‘Thank you’ in French means ‘Mo, thank you.’
1. My Spanish friends wanted advice about ______.
A. learning English B. finding places to stay in England
C. driving their car on English roads D. going to England by car
2. I suggested that they stay at bed and breakfast houses because ______.
A. they would be able to practise their English
B. it would be much cheaper than staying in hotels
C. it would be convenient for them to have dinner
D. there would be no problem about finding accommodation there
3. “NO VACANCIES” in English means ______.
A. no free rooms B. free rooms C. not away on holiday D. holidays
4. If you see a road sign that says ‘Diversion’, you will ______.
A. fall into a hole
B. have a lot of fun and enjoy yourself
C. find that the road is blocked by crowds of people
D. have to take a different road
5. When someone offered me more coffee and I said ‘Thank you’ in French, I ______.
A didn’t really want any more coffee B. wanted them to take the coffee pot away
C. really wanted some more coffee D. wanted to express my politeness
6. I was surprised when the coffee pot was taken away because I ______.

Mr. Peter Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route --- through the boot(行李箱).
Mr. Johnson's car had finished up in a ditch (沟渠) at Romney Marsin, Kent after skidding on ice and hitting a bank. "Fortunately, the water began to come in only slowly," Mr. Johnson said. "I couldn't force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in."
Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape.
Later he said, "It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came."
It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench and began to work on the boot lock. Fifteen minutes passed by. "It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled clear as the car filled up."
His hands and arms cut and bruised (擦伤), Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer's wife, Mrs. Lucy Bates. Trembling in a blanket, he said, "That thirty minutes seemed like hours." Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.
21. What is the best title for this newspaper article?
A. The Story of Mr. Johnson, a Sweet Salesman
B. Car Boot Can Serve as the Best Escape Route
C. Driver Escapes through Car Boot
D. The Driver Survived a Terrible Car Accident
22. The underlined sentence in Paragraph 5 “Finally it gave” means that _______.
A. luckily the door was torn away in the end
B. at last the wrench went broken
C. the lock came open after all his efforts
D. the chance was lost at the last minute
23. It can be inferred from the passage that _______.
A. the ditch was along a quiet country road
B. the accident happened on a clear warm day
C. the police helped Mr. Johnson get out of the ditch
D. Mr. Johnson had a tender wife and was well attended
B
It’s easy to think of the selfless reasons to listen. People want you to listen to them. By listening, you can help someone with a problem, or help them come up with new ideas. But listening also has selfish benefits that make it worth the investment.
The biggest selfish benefit is that you learn more with your mouth closed. You’ll learn more about other people, and often, about yourself, if you stop talking. Those ideas are useful if you want to improve yourself.
Listening also helps you think. When you’re truly listening, not just waiting for your turn to speak, you can chew over your ideas more. You can mull on points of the conversation longer. In the end, you’ll appear a lot wiser if you explain a fully-digested point of view, than if you just speak out the first response that comes to mind. Building the listening habit also makes better friends than trying to be an impressive conversationalist. People like the guy who listens more than the guy with the best jokes. Be interested, rather than interesting.
If the person you’re talking with doesn’t feel too chatty, bait (启发) them with a comment. Throw something at them which will make it easy for them to talk. A better strategy to listen is to master the short anecdote. This is a 2-3 sentence comment on something that the other person has said. If they are telling a long explanation of their work as an accountant, you could comment on someone you know that does accounting or something you know about accounting.
24. The following are talked about EXCEPT ______.
A. the ways of being a good listener
B. the benefits of building the listening habit
C. the ways of being a good speaker
D. the strategies to inspire others to speak
25. According to the passage, which kind of person is most probably popular with people?
A. The one who is good at telling jokes.
B. The one who has no speaking ability.
C. The one who is good at public speaking.
D. The one who is good at listening to others.
26. The underlined phrase “mull on” in the third paragraph means ______.
A. think over B. agree with C. disagree with D. put forward
C
New York’s long awaited bike share program, which arranged the distribution of 10,000 bicycles along some of the city’s busiest street, will be sponsored by Citi financial group, Mayor Michael Bloomberg announced on Monday.
Citi Bike will be the largest public bike share system in the US, with bikes placed in 600 stations in Manhattan and Brooklyn. The program will be operated by Alta bicycle share, which runs similar projects in Washington D.C. and Boston.
“The idea behind bike share is simple: give people one more way to get around the town,” Bloomberg said in a restaurant. “The new Citi Bikes will be an affordable transportation network that will help New Yorkers get where they’re going faster. When the walk seems a little far, New Yorkers can choose to skip the hike, and take a bike.”
The program was announced in September 2011, and the department of transport has spent the last eight months planning locations for the stations. Full details on the locations have not been released yet, but they will include Times Square, Penn Station and close to Central Park.
Annual membership of the program will cost $95, which entitles (授权) users to free journeys up to 45 minutes. For those unwilling to commit to a year’s cycling, seven-day subscriptions are available for $25 or 24-hour access for $9.95, with the first 30 minutes of any journey free. The official website for the program – citibikenyc – says the pricing strategy is likely to ensure that riders keep their trips short. Although short journeys are free, anyone wanting to take a bike for the day will face very high charges. People who do not sign up to an annual membership – tourists, for example, would pay $49 for a three-hour ride, plus the $9.95 24-hour access fee, making a total of $59.
The department of transport said the bikes and stations, which will begin to be fixed from “late July”, will be the same as in London, Montreal and Minneapolis; however, in one sense Bloomberg will be hoping the New York program differs from that of London. While the London program has ended up losing money since it launched in 2010, the mayor said New York City would “split system profits with the operator”, creating a potential new income program.
27. According to the passage, the main purpose of setting up New York’s bike share system is to ________.
A. make profits from the bike users
B. discourage people from going hiking
C. reduce people’s expenses on transportation
D. help people travel around the city more easily
28. According to the passage, which of the following locations is NOT available for the Citi Bike service?
A. Central Park B. Time Square
C. Brooklyn Botanic Garden D. Penn Station
29. What can be learned from Paragraph 5?
A. It is wise of people to use the bikes for short trips.
B. Anyone can use the bike free of charge for 45 minutes.
C. Most people are unwilling to pay for the annual membership.
D. Tourists are charged more for the use of bikes than local people.
30. In what sense does Bloomberg hope the New York program differs from that of London?
A. Better accepted. B. Better operated.
C. More profitable. D. More widespread.

切线的倾斜角为0°或90°,由f′(x)=6x2-x=0可得x=0或x=,故选C.
易错点拨:常见函数的切线的斜率都是存在的,所以倾斜角不会是90°.
2.设函数f(x)=则满足f(x)≤2的x的取值范围是()
A.[-1,2] B.[0,2]
C.[1,+∞) D.[0,+∞)
答案:D命题立意:本题考查分段函数的相关知识,求解时可分为x≤1和x>1两种情况进行求解,再对所求结果求并集即得最终结果.
解题思路:若x≤1,则21-x≤2,解得0≤x≤1;若x>1,则1-log2 x≤2,解得x>1,综上可知,x≥0.故选D.
3.函数y=x-2sin x,x的大致图象是()
答案:D解析思路:因为函数为奇函数,所以图象关于原点对称,排除A,B.函数的导数为f′(x)=1-2cos x,由f′(x)=1-2cos x=0,得cos x=,所以x=.当00,函数单调递增,所以当x=时,函数取得极小值.故选D.
4.已知函数f(x)满足竖宏:当x≥4时,f(x)=2x;当x<4时,f(x)=f(x+1),则f=()
A. B. C.12 D.24
答案:D命题立意:本题考查指数式的运算,难度中等.
解题思路:利用指数式的运算法则求解.因为2+log =2+log2 3(3,4),所以f=f=f(3+log2 3)=23+log2 3=8×3=24.
5.已知函数f(x)=若关于x的方程f2(x)-af(x)=0恰好有5个不同的实数解,则a的取值范围是()
A.(0,1) B.(0,2) C.(1,2) D.(0,3)
答案:
A解题思路:设t=f(x),则方程为t2-at=0,解得t=0或t=a,
即f(x)=0或衡伍f(x)=a.
如图,作出函数的图象,
由函数图象可知,f(x)=0的解有两个,
故要使方程f2(x)-af(x)=0恰有5个不同的解,则方程f(x)=a的解必有三个,此时0
6.若R上的奇函数y=f(x)的图象关于直线x=1对称,且当0
A.4 020 B.4 022 C.4 024 D.4 026
答案:B命题立意:本题考查函数性质的应用及数形结合思想,考查推理与转化能力,难度中等.
解题思路:由于函数图象关于直线x=1对称,故有f(-x)=f(2+x),又函数为奇函数,故-f(x)=f(2+x),从而得-f(x+2)=f(x+4)=f(x),即函数以4为周期,据题意其在一个周期内的图象如图所示.
又函数为定义在R上的奇函数,故f(0)=0,因此f(x)=+f(0)=,因此在区间(2 010,2 012)内的函数图象可由区间(-2,0)内的图象向右平移2 012个单位得到,此时两根关于直线x=2 011对称,故x1+x2=4 022.
7.已知函数满足f(x)=2f,当x[1,3]时,f(x)=ln x,若在区间内,函数g(x)=f(x)-ax有三个不同零点,则实数a的取值范围是()
A. B.
C. D.
答案:A思路点拨:当x∈时,则1<≤3,
f(x)=2f=2ln=-2ln x.
f(x)=
g(x)=f(x)-ax在区间内有三个不同零点,即函数y=与y=a的图象在上有三个不同的交点.
当x∈时,y=-,
y′=<0,
y=-在上递减,
y∈(0,6ln 3).
当x[1,3]时,y=,
y′=,
y=在[1,e]上递增,在[e,3]上递减.
结合图象,所以y=与y=a的图象有三个交点时,a的取值范围为.
8.若函数f(x)=loga有最小值,则实数a的取值余拦册范围是()
A.(0,1) B.(0,1)(1,)
C.(1,) D.[,+∞)
答案:C解题思路:设t=x2-ax+,由二次函数的性质可知,t有最小值t=-a×+=-,根据题意,f(x)有最小值,故必有解得1
9.已知函数f(x)=若函数g(x)=f(x)-m有三个不同的零点,则实数m的取值范围为()
A. B.
C. D.
答案:
C命题立意:本题考查函数与方程以及数形结合思想的应用,难度中等.
解题思路:由g(x)=f(x)-m=0得f(x)=m,作出函数y=f(x)的图象,当x>0时,f(x)=x2-x=2-≥-,所以要使函数g(x)=f(x)-m有三个不同的零点,只需直线y=m与函数y=f(x)的图象有三个交点即可,如图.只需-
10.在实数集R中定义一种运算“*”,对任意给定的a,bR,a*b为确定的实数,且具有性质:
(1)对任意a,bR,a*b=b*a;
(2)对任意aR,a*0=a;
(3)对任意a,bR,(a*b)*c=c*(ab)+(a*c)+(c*b)-2c.
关于函数f(x)=(3x)*的性质,有如下说法:函数f(x)的最小值为3;函数f(x)为奇函数;函数f(x)的单调递增区间为,.其中所有正确说法的个数为()
A.0 B.1 C.2 D.3
答案:B解题思路:f(x)=f(x)*0=*0=0]3x×+[(3x)*0]+)-2×0=3x×+3x+=3x++1.
当x=-1时,f(x)0,得x>或x<-,因此函数f(x)的单调递增区间为,,即正确.
二、填空题
11.已知f(x)=若f[f(0)]=4a,则实数a=________.
答案:2命题立意:本题考查了分段函数及复合函数的相关知识,对复合函数求解时,要从内到外逐步运算求解.
解题思路:因为f(0)=2,f(2)=4+2a,所以4+2a=4a,解得a=2.
12.设f(x)是定义在R上的奇函数,在(-∞,0)上有2xf′(2x)+f(2x)<0且f(-2)=0,则不等式xf(2x)<0的解集为________.
答案:(-1,0)(0,1)命题立意:本题考查函数的奇偶性与单调性的应用,难度中等.
解题思路:[xf(2x)]′=2xf′(2x)+f(2x)<0,故函数F(x)=xf(2x)在区间(-∞,0)上为减函数,又由f(x)为奇函数可得F(x)=xf(2x)为偶函数,且F(-1)=F(1)=0,故xf(2x)<0F(x)<0,当x0时,不等式解集为(0,1),故原不等式解集为(-1,0)(0,1).
13.函数f(x)=|x-1|+2cos πx(-2≤x≤4)的所有零点之和为________.
答案:6命题立意:本题考查数形结合及函数与方程思想的应用,充分利用已知函数的对称性是解答本题的关键,难度中等.
解题思路:由于函数f(x)=|x-1|+2cos πx的零点等价于函数g(x)=-|x-1|,h(x)=2cos πx的图象在区间[-2,4]内交点的横坐标.由于两函数图象均关于直线x=1对称,且函数h(x)=2cos πx的周期为2,结合图象可知两函数图象在一个周期内有2个交点且关于直线x=1对称,故其在三个周期[-2,4]内所有零点之和为3×2=6.
14.已知函数f(x)=ln ,若f(a)+f(b)=0,且0
答案:命题立意:本题主要考查对数函数的运算,函数的值域,考查运算求解能力,难度中等.
解题思路:由题意可知,ln +ln =0,
即ln=0,从而×=1,
化简得a+b=1,
故ab=a(1-a)=-a2+a=-2+,
又0
故0<-2+<.
B组

1.已知偶函数f(x)在区间[0,+∞)单调递减,则满足不等式f(2x-1)>f成立的x取值范围是()
A. B.
C. D.
答案:B解析思路:因为偶函数的图象关于y轴对称,在区间[0,+∞)单调递减,所以f(x)在(-∞,0]上单调递增,若f(2x-1)>f,则-<2x-1<,
