2.(-∞,1) 3.2π3 4.-513 5.126.9 7.-148.5 9.c <a <b 10.1 11.3 12.4 13.(0,13)∪(3,+∞) 14.(0,14) 二、解答题:本大题共6小题,共90分.15. 解:(1)因为sin α+cos αsin α-2cos α=2,化简得sin α=5cos α. ……………………………2分 当cos α=0时不符合题意,所以cos α≠0,所以tan α=5. ………………………………………………6分(2)cos(π2-α)·cos(-π+α)=-sin αcos α ……………………………8分 =-sin α·cos αsin 2α+cos 2α=-tan αtan 2α+1…………………………………………12分 =- 526. ……………………………………………14分 16.解:(1)因为a =(-2,1),b =(3,-4),所以a +b =(1,-3),2a -b =(-7,6), ……………………4分所以(a +b )·(2a -b )=1×(-7)+(-3)×6=-25. ……………………6分(2)由(1)可知a +b =(1,-3),且a =(-2,1),所以|a |=5,|a +b |=10,a ·(a +b )=-5. ……………………9分设向量a 与a +b 的夹角为θ,则cos θ=a ·(a +b )|a |·|a +b |=-22. ……………………11分 因为θ∈[0,π],所以θ=3π4,即向量a 与a +b 的夹角为3π4. ……………………14分 17.解:(1)依题意,y =x (a -2x )(2a -2x ),x ∈(0,1]. ………………………………4分(2)y =V (x )x=(a -2x )(2a -2x ) …………………………………6分 =4x 2-6ax +2a 2.因为对称轴x =34a ,且a >2 ,所以x =34a >32>1, …………………………8分 所以当x =1,y min =4-6a +2a 2. ………………………12分答:当x =1时,y 最小,最小值为4-6a +2a 2. …………………………14分18. 解:(1)由T =2πω,得2πω=π,所以ω=2. 因为点P (π6,2)是该函数图象的一个最高点,且A >0,所以A =2.…………2分 此时f (x )=2sin(2x +φ).又将点P (π6,2)的坐标代入f (x )=2sin(2x +φ), 得2sin(π3+φ)=2,即sin(π3+φ)=1, 所以π3+φ=2k π+π2,k ∈Z ,即φ=2k π+π6,k ∈Z . ………………………4分 又因为|φ|<π2,所以φ=π6. 综上,f (x )=2sin(2x +π6). ………………………6分 (2) 因为x ∈[-π2,0],所以2x +π6∈[-5π6,π6], ………………………8分 所以sin(2x +π6)∈[-1,12],即2sin(2x +π6)∈[-2,1], 所以函数y =f (x )的值域为[-2,1]. ………………………10分(3)y =g (x )=2sin[2(x -θ)+π6]=2sin(2x -2θ+π6). ………………………12分 因为0≤x ≤π4,所以π6-2θ≤2x -2θ+π6≤2π3-2θ, 所以⎩⎨⎧π6-2θ≥2k π-π2,2π3-2θ≤2k π+π2,k ∈Z , 解得-k π+π12≤θ≤-k π+π3,k ∈Z . ………………………14分 因为0<θ<π2,所以k =0,所以π12≤θ≤π3. ………………………16分 19.解:(1)因为AB →=CB →-CA →, ………………………2分所以AB →2=(CB →-CA →)2=CB →2-2CB →·CA →+CA →2=22-2×2×1×12+12=3, 所以|AB →|=3. ………………………4分(2)解法1:①当λ=12时,AE →=12CB →-CA →,CD →=12(CB →+CA →). ……………………6分 所以AE →·CD →=(12CB →-CA →)·12(CB →+CA →)=12×(12CB →2-12CB →·CA →-CA →2) =12×(12×22-12×2×1×12-12)=14. …………………8分 ②假设存在非零实数λ,使得AE →⊥CD →.因为BE →=λBC →,所以AE →=CE →-CA →=(1-λ)CB →-CA →. …………………10分因为AD →=λAB →,所以CD →=CA →+AD →=CA →+λAB →=CA →+λ(CB →-CA →)=λCB →+(1-λ)CA →. ……………………12分所以AE →·CD →=[(1-λ)CB →-CA →]·[λCB →+(1-λ)CA →]=λ(1-λ)CB →2+(λ2-3λ+1)CB →·CA →-(1-λ)CA →2=λ(1-λ)×22+(λ2-3λ+1)×2×1×12-(1-λ)×12 =-3λ2+2λ=0. ………………………14分解得λ=23或λ=0. 因为点在三角形的边上,所以λ∈[0,1],故存在非零实数λ=23,使得AE →⊥CD →. ………………………16分 解法2:由(1)得CA =1,CB =2,AB =3,满足CB 2=AB 2+CA 2, 所以∠CAB =90︒.如图,以A 原点,AB 边所在直线为x 轴,AC 边所在的直线为y 轴,建立平面直角坐标系,则A (0,0),B (3,0),C (0,1). ……………6分 ①当λ=12时,AE →=(32,12),CD →=(32,-1), 则AE →·CD →=14. ………………………10分 ②假设存在非零实数λ,使得AE →⊥CD →.因为AE →=(3(1-λ), λ),CD →=(3λ,-1),所以AE →·CD →=-3λ2+2λ=0, ………………………14分解得λ=0或λ=23. 因为点在三角形的边上,所以λ∈[0,1],所以存在非零实数λ=23,使得AE →⊥CD →. ………………………16分 20.解:(1)F (x )=f (x )-g (x )=x -a -a |x |.①当a =12时,由F (x )=0,得x -12-12|x |=0. 当x ≥0时,x -12-12x =0,解得x =1,满足条件. 当x <0时,x -12+12x =0,解得x =13,不满足条件. 综上,函数y =F (x )的零点是1. ………………………2分②F (x )=0,则x -a -a |x |=0,即a (1+|x |)=x .因为1+|x |≠0,所以a =x 1+|x |. ………………………4分 设φ(x )=x 1+|x |, 当x >0时,φ(x )=x 1+x =1-11+x,所以φ(x )∈(0,1). ………………………6分 因为φ(-x )=-φ(x ),所以φ(x )是奇函数,所以当x <0时,φ(x )∈(-1,0).又因为φ(0)=0,所以当x ∈R ,φ(x )∈(-1,1),所以a ∈(-1,1). ………………………8分(2)设函数h (x )的最大值和最小值分别是M ,N .因为对任意x 1,x 2∈[-2,2],| h (x 1)-h (x 2)|≤6成立,所以M -N ≤6. ………………………10分解法1:因为h (x )=f (x )+g (x )=x -a +a |x |,x ∈[-2,2],所以h (x )=x -a +a |x |=⎩⎨⎧(a +1)x -a ,x ≥0,(1-a )x -a ,x <0.①当a >1时,因为a +1>0,所以h (x )在(0,+∞)单调增;因为1-a <0,所以h (x )在(-∞,0)单调减.因为h (2)=a +2,h (-2)=a -2,所以h (2)>h (-2),所以M =h (x )max =h (2)=a +2,N =h (x )min =h (0)=-a ,所以a +2-(-a )≤6,解得a ≤2.又因为a >1,所以1<a ≤2. ………………………12分②当a =1时,h (x )=⎩⎨⎧2x -1,x ≥0,-1, x <0,所以M =h (x )max =h (2)=3,N =h (x )min =-1,所以3-(-1)≤6恒成立,所以 a =1符合题意.③当-1<a <1时,因为a +1>0,所以h (x )在(0,+∞)单调增;因为1-a >0,所以h (x )在(-∞,0)单调增.所以M =h (x )max =h (2)=a +2,N =h (x )min =h (-2)=a -2,所以(a +2)-(a -2)=4≤6恒成立,所以-1<a <1符合题意.④当a =-1时,h (x )=⎩⎨⎧1, x ≥0,2x +1,x <0,所以M =h (x )max =1,N =h (x )min =h (-2)=-3,所以1-(-3) =4≤6恒成立,所以a =-1符合题意. ……………………14分⑤当a <-1时,因为a +1<0,所以h (x )在(0,+∞)单调减;因为1-a >0,所以h (x )在(-∞,0)单调增.所以M =h (x )max =h (0)=-a ,因为h (2)=a +2,h (-2)=a -2,所以h (2)>h (-2) ,所以N =h (x )min =h (-2)=a -2,所以-a -(a -2)≤6,解得a ≥-2.又因为a <-1,所以-2≤a <-1.综上,a 的取值范围为[-2,2]. ……………………16分解法2:因为h (x )=f (x )+g (x )=x -a +a |x |,x ∈[-2,2],所以h (x )=x -a +a |x |=⎩⎨⎧(a +1)x -a ,x ≥0,(1-a )x -a ,x <0.可知函数的图象是由两条折线段构成.所以函数的M 和N 分别为h (-2)=-2+a ,h (0)=-a ,h (2)=2+a 三个值当中的两个. 显然2+a >-2+a .当a ≤-1时,2+a ≤-a ;当a >-1时,2+a >-a .当a ≤1时,-2+a ≤-a ;当a >1时,-2+a >-a .所以,①当a >1时,M =2+a ,N =-a ,M -N =2+2a ,因为M -N ≤6,所以a ≤2.又因为a >1,所以1<a ≤2. …………………12分②当-1<a ≤1时,M =2+a ,N =-2+a ,M -N =4.因为M -N ≤6恒成立,所以-1<a ≤1满足条件. …………………14分③当a ≤-1时,M =-a ,N =-2+a ,M -N =2-2a .因为M -N ≤6,所以a ≥-2.又因为a ≤-1,所以-2≤a ≤-1.综上,a 的取值范围为[-2,2]. ………………………16分解法3:因为h (x )=f (x )+g (x )=x -a +a |x |,x ∈[-2,2],所以h (x )=x -a +a |x |=⎩⎨⎧(a +1)x -a ,x ≥0,(1-a )x -a ,x <0.①当0≤x≤2,h(x)=(1+a)x-a.若a>-1,则1+a>0,所以h(x)=(1+a)x-a是增函数.所以h(x)max=h(2)=2+a,h(x)min=h(0)=-a.若a<-1,则1+a<0,所以h(x)=(1+a)x-a是减函数.所以h(x)max=h(0)=-a,h(x)min=h(2)=2+a.若a=-1,h(x)=1,所以h(x)max=h(x)min=1.②当-2≤x<0,h(x)=(1-a)x-a.若a<1,则1-a>0,所以h(x)=(1-a)x-a是增函数.所以h(x)<h(0)=-a,h(x)min=h(-2)=-2+a.若a>1,则1-a<0,所以h(x)=(1-a)x-a是减函数.所以h(x)max=h(-2)=-2+a,h(x)>h(0)=-a.若a=1,h(x)=-1,所以h(x)max=h(x)min=-1.………………12分显然2+a>-2+a.因为当a≤-1时,2+a≤-a;当a>-1时,2+a>-a;当a≤1时,-2+a≤-a;当a>1时,-2+a>-a.………………………14分所以,(Ⅰ)当a>1时,M=2+a,N=-a,M-N=2+2a.因为M-N≤6,所以a≤2.又因为a>1,所以1<a≤2.(Ⅱ)当-1<a≤1时,M=2+a,N=-2+a,M-N=4.因为M-N≤6恒成立,所以-1<a≤1满足条件.(Ⅲ)当a≤-1时,M=-a,N=-2+a,M-N=2-2a.因为M-N≤6,所以a≥-2.又因为a≤-1,所以-2≤a≤-1.综上,a的取值范围为[-2,2].………………………16分。

When you go out into the world, 26 traffic, hold hands and stick together. The root goes 27 and the plant goes up and 28 really knows how or why, but we are all like that.And then 29 the book about Dick and Jane and the first 30 you learned, the biggest word of all:Look. Everything you 31 is in there somewhere.32 what a better world it would be if we all—the whole world—had cookies and milk about 3 o’clock every afternoon and then 33 down with our blankets for a nap. 34 if we had a basic policy in our countries to always put things back where you found them and cleaned up our own messes. And it is still true. No matter how 35 you are, when you go out into the world, it is better to hold hands and stick together.21. A. Master B. Make C. Take D. Share22.

A. wise B. old C. energetic D. goodBAs we all know, English is nowadays more and more important and popular around the world. But 36 English is a language with so many confusing rules may be a question to many people. So let’s look back upon the 37 of it, which may be divided into three part s——Old English, Middle English and Modern English.As for Old English, three Germanic groups from the 38 mainland——the Angles, the Saxons and the Jutes——invaded (侵略) Britain. They 39 had their own language and Angles-Saxon developed from 40 these languages with Celtic which 41 before the middle of the 5th century. At the end of the 9th century, the Vikings began to invade Britain, and brought 42 them their languages, which also mixed with Angle-Saxon and 43 what we now call Old English. This language different from the English we speak nowadays 44 made up of an Angle-Saxon base plus words from the language of Denmark and Norway.Middle English is the name 45 to the English used from around the 12th and 16th century. Many factors 46 the development of this new type of English. French had an 47 on the English language, which created even more pairs of similar words like “reply” and “answer”.Modern English began during the Renaissance(文艺复兴)in the 16th century. 48 this, Modern English includes many Latin and Greek words. Pronunciation also experienced huge changes during this period The question of 49 English will continue changing in the future is easy to answer. Even today, if a person from the south of England goes to the north, he or she may find it difficult 50 what people there are saying because English is still changing.36.

There is often wasted space when they store watermelons, because round watermelons do not sit nicely on shelves. So some clever farmers have solved the watermelon problem. They make their watermelons grow in square glass boxes so the watermelons become square. The only problem now is the price. The square watermelons cost about 80 dollars each.Many people know the saying “Roses are red, violets are blue, sugar is sweet and so are you”. Well, today the poem needs to change to “Roses are red, roses are blue”! Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose, they can create a nearly 100% blue rose. Some of science’s inventions are beautiful, not just useful!Since the mid-1990s, many Chinese farmers have had amazing rice harvests. For many years Chinese scientists have been working on developing new kinds of stronger rice and now they have produced a new kind, called super rice. Super rice not only can protect itself against insects and diseases, but it also produces more than any other kind of rice. Today farmers can grow almost one and a half times more rice than they could grow in the past.Doctors might be able to use vegetables to fight cancer now. US scientists have discovered a way to put a chemical into tomato plants while they are growing. When cancer patients eat the tomatoes, the tomatoes will fight the cancer in their bodies. These cancer-fighting vegetables are not yet for sale, because scientists have not finished testing them. If study finds no problems with the tomatoes, then patients can begin to use this easy and delicious new treatment.51. The square watermelons look like ____________.A. C. D.52. Which of the following is true?A. Super rice can keep itself from insects.B. Blue roses are more beautiful than red ones.C. The tomatoes can fight many kinds of diseases.D. The square watermelons cost less than ordinary ones.53. The main idea of this passage is ____________. A. how scientists discover new plantsB. how science makes plants produce moreC. how science has changed plants and people’s livesD. how technology makes our world more beautifulBFor most of us, Hawaii begins to show her charm little by little. A friend describes a sunset of Waikiki. We hear the twang (弹拨) of a guitar. We see golden beaches and golden people; we see sun, sand, sea, and surf…or somewhere between the blue skies and the palm trees. We’re completely attracted.The Hawaiian Islands are one of the most beautiful places on the earth. The weather is friendly. The temperature changes from 60-90 degrees all year long. It’s a little warmer in summer, and a little cooler in winter, but every day is a beach day for somebody.The environment is friendly. The beauty of Hawaii is almost unparalleled. Amazing mountains were created millions of years ago by volcanic activity that pushed these islands three miles away from the ocean floor. Wave action created coral reefs (珊瑚礁) and then broke them to create miles of white sand beach. The position (地理位置) at the center of the Pacific Ocean made sure that almost every plant and animal that would find a home here would come as an invited visitor.There are no strangers in Paradise. Perhaps the most beautiful part of Hawaii is the sincere warmth of our people. We call it the spirit of Aloha. It has allowed people from all over the world to find common ground, and a new home, in this most gentle place.54. What is the best title for the passage?A. The beauty of Hawaii.B. Friendly people in Hawaii.C. Hawaii —our paradise.D. Everyday is a beach day.55. The underlined word “unparalleled” probably means “________’’.A. unmatchedB. unnoticedC. uncomfortableD. unimportant56. What is implied (暗示) but not described is that________.A. the people in Hawaii are very friendlyB. the writer’s friend has been to HawaiiC. the weather is very pleasant hereD. Hawaii is at the center of Pacific57. The underlined sentence means________.A. the strangers aren’t allowed to come hereB. people in Hawaii know each other very wellC. Hawaii makes people feel at homeD. the strangers find it hard to live in HawaiiCAn American exploration company, the Nauticos Corporation, has found the wreck(残骸) of an ancient (古代的)Greek ship in a very deep area of the Mediterranean Sea. It may be the deepest ancient shipwreck ever found. The discovery questions a long-held idea that ancient sailors didn’t have skills needed to guide ships in open seas.The ancient ship lay more than 3000 meters below the surface of the Mediterranean. The wreck was more than 489 kilometers from the Island of Corsica. Scientists believe the ship is about 2300 years old.The company was looking for an Israeli submarine(潜水艇) that had disappeared more than thirty years ago. Nauticos official Thomas Dettweiler said two company ships were searching for the Israeli submarine. He supervised(监督)the operation from a ship with sonar equipment. A sonar system uses sound waves to find and identify objects under the water. A second ship carried a vehicle for deep-sea searches.During the search, one ship’s sonar began making strange sounds. Mr. Dettweiler thought this meant they had found the lost submarine. He ordered the other ship to send down the deep-sea vehicle to search.But a video camera on the vehicle did not show a submarine. Instead, it showed many large clay containers lying on the bottom of the sea. These containers are called amphoras(古罗马和希腊的两耳细颈酒罐). Mr. Dettweiler was excited. He says he knew that the 2000 amphoras they had found meant they had discovered an important shipwreck. In ancient times such containers held wine, olive oil and other goods.Nauticos and the scientists hope to do more research in the area soon. Mr. Dettweiler believes four other ancient ships may be nearby. He says finding shipwrecks from different time periods could be especially important. It could be the first evidence of continued open-sea trading in the ancient world.58. Which of the following is NOT true?A. It is still believed that ancient sailors didn’t know how to guide ships in open sea.B. The ancient ship was discovered by an American exploration company.C. The ancient ship was found by chance.D. Four other ancient ships may be nearby.59. A sonar system __________.A. helps people to find any objectB. can only be used to look for shipsC. is a technology related to sea wavesD. can only be used under the water60. How did they know they had found an ancient shipwreck?A. The sonar system began to make sounds.B. The video camera showed the picture of a wrecked ship.C. They found amphoras.D. They found wine, olive oil and other products under the sea.61. Mr. Dettweiler hopes to find more ancient ships because _____.A. the ancient ships are usefulB. these ancient ships show the importance of open-sea tradingC. they are important in the Greek historyD. they may prove there was open-sea trading in ancient times.DLooking back on my childhood, I am sure that naturalists are born and not made. Although we were all brought up in the same way, my brothers and sisters soon left their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental arithmetic (心算).Before World War I we spent our summer holidays in Hungary. I don’t have a clear memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.I am a naturalist, not a scientist. I have a strong love of the natural world and my love had led me into different observations (观察). I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my mind. Suddenly you think you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.But curiosity, keen eyes, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the excellent and essential qualities required is self-discipline (自律), a quality I don’t have. A scientist, up to a certain point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.62. The first paragraph tells us the writer ______.A. was interested in flowers and insects in his childhoodB. lost his hearing when he was a childC. didn’t like his brothers and sistersD. was born into a naturalist’s family63. The writer can’t remember his relatives clearly because _______.A. he didn’t live very long with themB. the family was too largeC. he was too young when he lived with themD. he was fully busy observing nature64. It can be implied from the passage that the writer was _______.A. a scientist as well as a naturalistB. a naturalist but not a scientistC. no more than a born naturalistD. first of all a scientist65. The writer says that he is a naturalist rather than a scientist probably because he thinks he _______.A. has a great deal of trouble doing mental arithmeticB. doesn’t have some of the qualities required of a scientistC. just reads about other people’s observations and discoveriesD. thinks of how to solve problems in a most natural way第II卷非选择题(共20分)IV. 单词拼写(共10题,每小题0.5分,满分5分)根据所给汉语或首字母写出相应的单词,注意形式变化,每空限填一词66. Just as the old saying goes “don’t judge a book by its cover”, we shouldn’t judge a person by his/ her a__________.67. The President of the United States p____________ the heroes in World War II with medals.68. The ___________ (惊讶)look on his face showed that he knew nothing about the birthday party for him.69. Panda and other endangered animals need p__________ by all the people in China.70. More Hope Schools have been built with the money d_________ by people across the country.71.

There I would 16 the peace and quiet, watch the water rush 17 and listen to the singing of birds and the rustling of 18 in the trees. I would also watch the bamboo trees 19 under pressure from the wind and watch them 20 gracefully to their original position after the wind had 21 .When I think about the bamboo tree's ability to bounce back to its original position, the word "resilience"(恢复能力)comes to mind.

He moved there a few years ago, and I was eager to see his new place and meet his friends.My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him. He seemed unhappy with me if I didn’t got straight A’s and u nhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to try hard to think out things to say, feeling on guard.On the first day of my visit, we went out with one of my father’s fr iends for lunch at anoutdoor cafe. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.36. Why did the author feel bitter(痛苦) about her father as a young adult?A. He was silent most of the time.B. He was too proud of himself.C. He didn’t love his children.D. He expected too much of her.37. When the author went out with her father on weekends, she would feel ________.A. nervousB. sorryC. tiredD. safe38. What does the author think of her father after her visit to Tucson?A. More critical.B. More humorous.C. Easy-going and friendly.D. Strict and hard-working.39. The underlined words in the last paragraph refer to ________.A. the author’s sonB. the author’s fatherC. the friend of the author’s fatherD. the cafe owner40. We can infer from the passage that ________.A. the writer's father used to be strict with her when he was a childB. the writer's father worked hard but cared less for his familyC. it was possibly the first time that the writer had visited her father's new homeD. as a child, the writer loved her fatherBEveryone has got two personalities—the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sle eping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.If you go to sleep on your back, you’re a very open person. You normally trust people and y ou are easily influenced by fashion or new ideas. You don’t like to upset people, so you never express your real feelings. You’re quite shy and you aren’t very confident.If you sleep on your stomach, you are a rather secretive(不坦率的)person. You worry a lot and you’re always easily upset. You’re very stubborn(顽固的), but you aren’t very ambitious. You’re usually live for today not for tomorrow. This means that you enjoy having a good time.If you sleep curled up (卷曲),you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel anxious, but you don’t often get depressed. You always say what y ou think even if it annoys people.41. According to the writer, you naturally show your secret and real personality .A. only in a normal nightB. only when you go to sleepC. only when you refuse to show yourself to the wordD. only when you change sleeping position42. Which is NOT mentioned in the second paragraph about a person’s personality?A. He or she is always open with others.B. He or she always likes new ideas earlier than others.C. He or she is always easily upset.D. He or she tends to believe in others.43. Point out which sentence is used to show the personality of a person who is used to sleeping on his or her stomach?A. He or she is careful not to offend others.B. He or she doesn’t want to stick to his or her opinion.C. He or she can’t be successful in any business.D. He or she likes to bring others happiness.44. Which of the following may be the reason for you not to make friends with a person who sleeps curled up?.A. He or she would rather be alone than communicate with you.B. He or she is rarely ready to help you.C. He or she prefers staying at home to going out.D. He or she wouldn’t like to get help from you.45. It appears that the writer tends to think highly of the person who sleeps on one side because .A. he or she always shows sympathy for peopleB. he or she is confident, but not stubbornC. he or she has more strengths than weaknessesD. he or she often considers annoying peopleCFirst of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult (侮辱). For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn't in the sandwich, but in the way students deal with the conflict.Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution (解决) stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words, name-calling, and accusation only add fuel to the emotional fir On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control.After both sides have calmed down, they can use another key strategy for conflict resolution; listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non-threatening questions to clarify the speaker's position. Then the two people should change roles.Finally, students need to consider what they are hearing. This doesn't mean trying to figure out what's wrong with the other person. It means understanding what the real issue is and what both sides are trying to accomplish. For example, a shouting match over a peanut butter sandwich might happen because one person thinks the other person is unwilling to try new things. Students need to ask themselves questions such as these: How did this start? What do I really want? Whatam I afraid of? As the issue becomes clearer, the conflict often simply becomes smaller. Even if it doesn't, careful thought helps both sides figure out a mutual solution.There will always be conflict in schools, but that doesn't mean there needs to be violence. After students in Atlanta started a conflict resolution program, according to Educators for Social Responsibility, "64 percent of the teachers reported less physical violence in the classroom; 75 percent of the teachers reported an increase in student cooperation; and 92 percent of the students felt better about themselves". Learning to resolve conflicts can help students deal with friends,. teachers. parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country.46. This article is mainly about__________.A. the lives of school childrenB. the cause of arguments in schoolsC. how to analyze youth violenceD. how to deal with school conflicts47. From Paragraph 2 we can learn that________ .A. violence is more likely to occur at lunchtimeB. a small conflict can lead to violenceC. students tend to lose their temper easilyD. the eating habit of a student is often the cause of a fight48. Why do students need to ask themselves the questions stated in Paragraph 5?A. To find out who to blame.B. To get ready to buy new things.C. To make clear what the real issue is.D. To figure out how to stop the shouting match.49. After the conflict resolution program was started in Atlanta, it was found that______.A. there was a decrease in classroom violenceB. there was less student cooperation in the classroomC. more teachers fell better about themselves in schoolsD. the teacher-student relationship greatly improved50. The writer’s purpose for writing this article is to_______.A. complain about problems in school educationB. teach students different strategies for school lifeC. advocate teaching conflict management in schoolsD. inform teachers of the latest studies on school violence第II卷非选择题(共35 分)IV. 单词拼写(共10小题;每小题1分,满分10分)根据所给首字母或汉语,写出相应的单词。

的长,根据AC的方程,求出点B到直线AC的距离,从而求出三角形ABC的面积即可.【解答】解:(1)因为点B(4,6),C(0,8),则k BC==﹣,因为l⊥BC,则l的斜率为2.又直线l过点A,所以直线l的方程为y=2(x﹣3),即2x﹣y﹣6=0.(2)因为点A(3,0),C(0,8),则|AC|==,又直线AC的方程为+=1,即8x+3y﹣24=0,则点B到直线AC的距离d==,所以△ABC的面积S=|AC|×d=13.16.已知圆C经过A(﹣2,1),B(5,0)两点,且圆心C在直线y=2x上.(1)求圆C的标准方程;(2)设动直线l:(m+2)x+(2m+1)y﹣7m﹣8=0与圆C相交于P,Q两点,求|PQ|的最小值.【考点】圆的一般方程.【分析】(1)设圆C的方程为x2+y2+Dx+Ey+F=0,建立方程组,即可求圆C的标准方程;(2)直线l过定点M(3,2).由圆的几何性质可知,当l⊥CM时,弦长|PQ|最短.【解答】解:(1)设圆C的方程为x2+y2+Dx+Ey+F=0,则,解得D=﹣4,E=﹣8,F=﹣5.所以圆C的方程是x2+y2﹣4x﹣8y﹣5=0,即(x﹣2)2+(y﹣4)2=25.(2)直线l的方程化为(2x+y﹣8)+m(x+2y﹣7)=0.令,得x=3,y=2,所以直线l过定点M(3,2).由圆的几何性质可知,当l⊥CM时,弦长|PQ|最短.因为|CM|==则|PQ|min=2=417.如图,在三棱柱ABC﹣A1B1C1中,A1A⊥平面ABC,AB⊥AC,AB=AC=AA1,D为BC的中点.(1)证明:A1B⊥平面AB1C;(2)求直线A1D与平面AB1C所成的角的大小.【考点】直线与平面所成的角;直线与平面垂直的判定.【分析】(1)证明A1A⊥AC.AC⊥A1B.推出AB1⊥A1B.即可证明A1B⊥平面AB1C.(2)连结A1C,设AB1∩A1B=O,连CO,交A1D于G.说明G为△A1BC的重心.推出∠A1GO是A1D与平面AB1C所成的角.设AB=AC=AA1=1,在Rt△A1OG中,求解直线A1D与平面AB1C所成的角为60°.【解答】(1)证明:图1所示,因为A1A⊥平面ABC,则A1A⊥AC.又AC⊥AB,则AC⊥平面AA1B1B,所以AC⊥A1B.由已知,侧面AA1B1B是正方形,则AB1⊥A1B.因为AB1∩AC=A,所以A1B⊥平面AB1C.(2)解:图2所示,连结A1C,设AB1∩A1B=O,连CO,交A1D 于G.因为O为A1B的中点,D为BC的中点,则G为△A1BC的重心.因为A1O⊥平面AB1C,则∠A1GO是A1D与平面AB1C所成的角.设AB=AC=AA1=1,则A1B=BC=A1C=.得A1O=,A1G=A1D=sin 60°=,在Rt△A1OG中,sin∠A1GO=,则∠A1GO=60°.所以直线A1D与平面AB1C所成的角为60°..一、本大题共2个小题,每小题5分,共12分.18.已知集合,则N∩∁R M= [0,2].【考点】交、并、补集的混合运算.【分析】先分别求出集合M和N,由此能求出N∩∁R M.【解答】解:集合,∴M=(﹣∞,0)∪(2,+∞),N=[0,+∞),∴N∩C R

(x)的图象关于原点对称,即f(x)为奇函数.由f(t2﹣2t)+f(﹣3)>0,得f(t2﹣2t)>﹣f(﹣3)=f(3),因为f(x)在R上是减函数,则t2﹣2t<3,即t2﹣2t﹣3<0,得﹣1<t<3.因为y==1+;在区间(﹣1,3)上是减函数,则.故选:B.二、本大题共3个大题,共38分.20.如图,四棱锥S﹣ABCD的底面是正方形,每条侧棱的长都是底面边长的倍,P为侧棱SD上的点.(Ⅰ)求证:AC⊥SD;(Ⅱ)若SD⊥平面PAC,则侧棱SC上是否存在一点E,使得BE∥平面PAC.若存在,求SE:EC的值;若不存在,试说明理由.【考点】直线与平面垂直的性质;直线与平面平行的判定.【分析】(Ⅰ)先证明AC⊥面SBD,然后利用线面垂直的性质证明AC⊥SD;(Ⅱ)利用线面平行的性质定理确定E的位置,然后求出SE:EC的值.【解答】解:(Ⅰ)连BD,设AC交BD于O,由题意SO⊥AC,在正方形ABCD中,AC⊥BD,所以AC⊥面SBD,所以AC⊥SD.(Ⅱ)若SD⊥平面PAC,则SD⊥OP,设正方形ABCD的边长为a,则SD=,OD=,则OD2=P D•SD,可得PD==,故可在SP上取一点N,使PN=PD,过N作PC的平行线与SC的交点即为E,连BN.在△BDN中知BN∥PO,又由于NE∥PC,故平面BEN∥面PAC,得BE∥面PAC,由于SN:NP=2:1,故SE:EC=2:1.21.设函数f(x)=mx2﹣mx﹣1,g(x)=.(1)若对任意x∈[1,3],不等式f(x)<5﹣m恒成立,求实数m 的取值范围;(2)当m=﹣时,确定函数g(x)在区间(3,+∞)上的单调性.【考点】函数恒成立问题.【分析】(1)利用f(x)<5﹣m,推出m<,设h(x)=,则当x∈[1,3]时,m<h(x)恒成立.利用二次函数的单调性求解m的取值范围.(2)推出g(x)=﹣(+).设x1>x2>3,则g(x1)﹣g(x2)=(x1﹣x2)(﹣),利用函数的单调性的定义证明即可.【解答】解:(1)由f(x)<5﹣m,得mx2﹣mx﹣1<5﹣m,即m (x2﹣x+1)<6.因为x2﹣x+1=(x﹣)2+>0,则m<.设h(x)=,则当x∈[1,3]时,m<h(x)恒成立.因为y=x2﹣x+1在区间[1,3]上是增函数,则h(x)在区间[1,3]上是减函数,h(x)min=h(3)=,所以m的取值范围是(﹣∞,).(2)因为f(x)=mx(x﹣1)﹣1,则g(x)=mx﹣.当m=﹣时,g(x)=﹣(+).设x1>x2>3,则g(x1)﹣g(x2)=﹣﹣==(x1﹣x2)(﹣)因为x1﹣1>x2﹣1>2,则(x1﹣1)(x2﹣1)>4,得<,又x1﹣x2>0,则g(x1)﹣g(x2)<0,即g(x1)<g(x2),所以g(x)在区间(3,+∞)上是减函数.22.已知圆C:(x﹣a)2+(y﹣a﹣2)2=9,其中a为实常数.(1)若直线l:x+y﹣4=0被圆C截得的弦长为2,求a的值;(2)设点A(3,0),O为坐标原点,若圆C上存在点M,使|MA|=2|MO|,求a的取值范围.【考点】直线与圆的位置关系.【分析】(1)利用圆心到直线的距离公式,结合直线l:x+y﹣3=0被圆C截得的弦长为2,利用勾股定理,可求a的值;(2)求出M在圆心为D(﹣1,0),半径为2的圆上,根据点M在圆C上,可得圆C与圆D有公共点,从而可得不等式,解不等式,即可求a的取值范围.【解答】解:(1)由圆方程知,圆C的圆心为C(a,a+2),半径为3.设圆心C到直线l的距离为d,因为直线l被圆C截得的弦长为2,则d2+1=9,即d=2.所以即|a﹣1|=2,所以a=﹣1或a=3.(2)设点M(x,y),由|MA|=2|MO|,化简得x2+y2+2x﹣3=0.所以点M在圆D:(x+1)2+y2=4上.其圆心为D(﹣1,0),半径为2.因为点M在圆C上,则圆C与圆D有公共点,即1≤|CD|≤5.所以1≤≤5,解得﹣5≤a≤﹣2或﹣1≤a≤2.故a的取值范围是[﹣5,﹣2]∪[﹣1,2].2017年2月23日。
