Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr White, an officer of forty, was strict with them and he hardly let them leave the camp.Once Mr White was ill in bed. He couldn’t work and a young officer, Mr Hunt began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when MrHunt decided to go to the town and see what was happening to the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they drank wine. Of course they found the officer was angry.“I’m sorry, sir,”said the first soldier. “I left the town on time. But something was wrong with my bus on my way here. I had to buy a horse and made it run fast. Bad luck! It died and I had to run back.”And the other seven soldiers said they were late for the same reasons. It was the last soldier’s turn. He said, “I’m sorry, sir. I got on a bus on time, but…”Having heard this, the officer became even angrier and stopped him at once. He called out, “If you say something was wrong with your bus, I’ll punish you at once!”“No, no, sir,”said the young man. “My bus was all right, but the horse died!”56. The military camp was built in the village to______ .A. stop the soldiers from going to townsB. stop the soldiers from meeting their friendsC. train the new soldiersD. make the young men live quietly57. Mr Hunt let the nine soldiers have a holiday because _____ .A. he was kind to themB. they felt lonelyC. they had something important to doD. they were the best of all58. The young officer was worried because ________ .A. a traffic accident had happenedB. he was afraid something happened to the nine soldiersC. the nine soldiers would come backD. the nine soldiers drank too much in the town59. The nine soldiers returned to the camp late because ________ .A. something was wrong with their busesB. their horses died on the return wayC. it took them much time to run backD. they all drank much in the townBHarry is eighteen now. He studies in a middle school. His parents like him very much and hope he can become a famous man. So they often tell him to study hard and they do all for him. They call him at six in the morning. After breakfast his father takes him to school in a car and in the afternoon, as soon as the young man comes back, the supper is ready. Of course, he never washes his clothes or goes to buy something in the shops.Once Harry’s father was sent to London on business. He would stay there for half a year. Before leaving, he told his wife to take good care of their son. The woman had to get up earlier and did all that her husband did before. And two months later she was so tired that she was ill in bed. Now the young man got into trouble. He couldn’t do any housework. He had to do as his mother told him. Even he didn’t know where to get on the bus!Yesterday Harry’s mother found his shoes were worn out and told him to buy a new pair in the shop. But he didn’t know how to choose. The woman had a sigh(叹息) and gave him a shoe pattern(鞋样) and told him to buy a pair of shoes himself. It’s Saturday today and Harry doesn’t go to school. With a policeman’s help, he found a shop. The shopkeeper was friendly to him. The man brought a lot of shoes and asked him to choose. When he was trying on a pair, suddenly he remembered something and took them off. The man was surprised and asked, “What’s the matter, young man?”“I’m sorry. I’ve left the shoe pattern at home!”60.Harry’s parents do all instead of him because _______.A. he’s too youngB. he has poor healthC. he’s busy with his studiesD. they hope he spends all time on studies61. _______ always does some housework in the morning.A. Harry’s fatherB. Harry’s motherC. HarryD. Nobody62. When the man was in London, _______.A. Harry had to stay at homeB.Harry fell behind in his classC. Harry couldn’t find the bus stopD. Harry wouldn’t go to school63. We can infer from the passage that _______.A. Harry wanted his mother to buy shoes for himB. Harry didn’t believe himselfC. Harry wouldn’t listen to his motherD. Harry was strong enough to buy shoes for himselfCMarch, April and May are months full of festivals and events all over the world. Here are some wonderful festivals around the world that happen in spring.SongKran--ThailandDates: 13th-15th, AprilIn Thailand, it’s time to celebrate the coming monsoon season, which will bring the rain many people have been looking forward to. They celebrate it with a festivalcalled Songkran,when people head out to the streets with water guns to spray(喷,洒)everyone who walks past. If you walk on the streets where the festival is celebrated, prepare to get soaked!Naghol--VanuatuDates: Every Saturday from April to MayEvery year, villagers come together to celebrate the harvest of yams, an important part in the people’s diet in Vanuatu. The festival is most famous for its “land diving ceremony”. During the ceremony men and boys dive to the ground from high wooden towers with only two thin vines(藤条) attached(附于)to their ankles(脚踝). The divers’heads have to lightly touch the ground when they jump---something very dangerous if the vines are not measured(测量)properly.Cherry Blossom Viewing ---JapanDates: The cherry blossom season is different from year to year depending on the weather forecast.The cherry blossom season has huge importance to the people of Japan, who celebrate the days when the flowers finally blossom. Only a few days later, the petals(花瓣)fall to the ground, like pink snowflakes. This is one of the most beautiful things to see. In Japan, almost everyone has picnics in the parks to view the flowers.Sinhalese New Year--Sri LankaDates: 13th or 14th, AprilJust like in many other countries in South an South East Asia, this is the time when the Sinhalese celebrate the traditional New Year, an ancient celebration which marks the end of the harvest season and is one of two times of the year when the sun is straight above Sri Lanka. There are a lot of delicious foods during the celebration.64. What does the underlined word “soaked”in Paragraph 2 probably mean?A.tiredB. wetC. crazyD. interested65. The writer thinks that the “land diving ceremony”can be dangerous for the divers because ___________.A. the divers may fall onto the ground if the thin vines breakB.the divers may bump into (撞在…上)the wooden tower on the way downC.the divers’ankles may get injured if the vines are tied too tightlyD.the divers may injure their heads if the vines aren’t measured properly66. We can learn from the passage that__________________.A. the Cherry Blossom Celebration usually lasts a long time in JapanB. the Cherry Blossom Celebration is the most important festival in JapanC. the time for the Cherry Blossom Celebration in Japan can be different yearlyD. people usually stay at home for celebration during the cherry blossom seasonDAl Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They asked him many questions, hoping to find an answer. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.Herpin died at the age of 94.67. The doctors came to Herpin’s home in order to ______.A. treat him for his illnessB. find the reason why some old people didn’t need any sleepC. get some proof to show his sleeplessness was not really trueD. help him to have a rest in some day68. After watching him closely, the doctors came to believe that Al Herpin ______.A. needed some kind of sleepB. needed no sleep at allC. was too old to need any sleepD. often slept in a chair69. The word “puzzle”in this passage probably refers to “______”.A. make you think a lot because you do not understand itB. make you worry a lot because you cannot sleep wellC. make you sad because something unusual has happenedD. make you fear because something terrible has happened70. The main idea of this passage is that ______.A. large numbers of people do not need sleepB. everyone needs some sleep to stay aliveC. people can live longer by trying not to sleep at allD. a person was found who actually didn’t need any sleep七选五:根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。

3=1∶2∶3,故选D 正确.2.解析: v a -v b =v a 0+at -(v b 0+at )=v a 0-v b 0,可见(v a -v b )为一定值,选项B 正确. 3.解析: 当a 的方向与v 0方向相同时,物体一定做加速直线运动.若a 一定,则为匀加速直线运动;当a 的方向与v 0的方向相反时,物体一定做减速直线运动.若a 一定,则为匀减速直线运动.4.解析: 设前后两段的加速度分别为a 1、a 2,开始刹车时汽车速度为v ,则a 1=vt 1,a 2=vt 2,所以a 1∶a 2=t 2∶t 1=1∶2.5.解析: 在这段时间内,由速度的表达式可知,火箭的速度均匀增大,故火箭做匀加速直线运动,选项D 错误;由匀变速直线运动的速度公式v =v 0+at 知,在这段时间内火箭的初速度v 0=4 m/s ,加速度a =2 m/s 2,选项A 、B 正确;将时间t =3 s 代入得v 3=10 m/s ,选项C 错误.6.答案: BC7.解析: 由题意知t 1=1 s 时,v 1=6 m/s ;t 2=2 s 时,v 2=8 m/s.由v 2=v 1+a (t 2-t 1)知,物体的加速度a =8-62-1 m/s 2=2 m/s 2.因为物体做匀加速运动,所以任何1 s 内速度的变化量都为Δv =a Δt =2×1 m/s =2 m/s.故B 、C 正确.由v 1=v 0+at 得,零时刻的速度v 0=v 1-at =6 m/s -2×1 m/s =4 m/s ,故A 不正确.第1 s 内的平均速度大于4 m/s ,小于6 m/s ,故D 不正确.8.解析: 解答本题的突破口是T ~2T 时间内的加速度跟0~T2时间内的加速度大小相等,方向相反,从而排除选项A 、B 、C ,本题选D.9.解析: 列车的加速度大小a =Δv Δt =50150 m/s 2=13 m/s 2,减速时,加速度方向与速度方向相反,a ′=-13 m/s 2,故A 、B 两项都正确.列车减速时,v -t 图象中图线依然在时间轴t 轴的上方,C 项错.由v =at 可得v =13×60 m/s =20 m/s ,D 项对.10.解析: 前80 s 内,乙车的位移大小是甲车位移大小的2倍,故乙车平均速度是甲车平均速度的2倍,A 项错;由图象知,70 s 末甲、乙两车的加速度大小相等、方向相反,B 项错;80 s 末两车相距最远,C 项错、D 项正确.11.解析: 物体朝一个方向运动,故x 不断增大,只有B 对. 12.解析: 图线与坐标轴围成图形的“面积”,即为位移大小.13.解析: 匀变速直线运动的位移与时间关系式为x =v 0t +12at 2,对比x =4t +2t 2,得出v 0=4 m/s ,a =4 m/s 2,B 正确.14.解析: 用v =v 0+at ,x =v 0t +12at 2求解,注意矢量的方向.15.解析: 乌龟一直做匀速运动,兔子先是没动,T 1时刻开始匀速前,T 2到T 4时间内又停止,T 4后又开始前进,A 错;兔子和乌龟都是从原点出发,B 对;兔子虽在T 4时刻发现落后奋力追赶,跑得比乌龟快,但由于时间太晚,还是让乌龟先到达预定位置x 3,C 错;在T 2~T 4,兔子停止不动,乌龟一直前进,D 错.16. 解析:17. 解析: 汽车运动时间t =v a =4 s <5 s ,则x =12at 2=12×5×42 m =40 m ,故C 对.18. 解析: 根据x -t 图象的物理意义可以判断选项A 在t =2 s 内物体的位移是0,根据v -t 图象与时间轴所围图形的面积在数值上等于物体的位移可以判断,选项C 、D 在t =2 s 内物体的位移是0,而B 选项在t =2 s 内物体的位移大于0,所以t =2 s 内物体位移最大的是B 选项.19.解析: 汽车从刹车到静止用时t 刹=v 0a =205 s =4 s ,故刹车后2 s 和6 s 内汽车的位移分别为x 1=x 0t -12at 2=⎝⎛⎭⎫20×2-12×5×22 m =30 m ,x 2=v 0t 刹-12at 2刹=⎝⎛⎭⎫20×4-12×5×42m =40 m ,x 1∶x 2=3∶4,D 选项正确.20.解析: 由图象可知0~2 s 时间内物体做匀加速直线运动,其加速度大小等于图线斜率大小即a =ΔvΔt =1.5 m/s 2,A 错误;3~7 s 时间内物体做匀减速直线运动.其加速度大小为a =ΔvΔt =0.75 m/s 2,B 正确;图线与t 轴围成的面积等于物体所发生的位移,故第3 s内的位移x =3.0×1 m =3.0 m ,C 正确;加速过程的位移x =12×2×3.0 m =3.0 m ,减速过程的位移x =12×4×3.0 m =6.0 m ,故D 正确.21.解析: 由v -t 图象知前8 s 内位移为Δx =x 1+x 2=12×3×2 m -12×(8-3)×2 m =-2m 负号表示位移方向与正方向相反,即水平向左.由平均速度公式得v =Δx Δt =-2 m8 s=-0.25 m/s 负号表示平均速度方向与正方向相反,即水平向左.故答案为A.22.解析: 由x =-5t 2+40t 变形得x =40t +12×(-10)t 2,故v 0=40 m/s ,a =-10 m/s 2,质点做匀减速直线运动,由数学知识知,当t 0=4 s 时,位移最大为x 0=80 m ,A 正确,B 、C 错误.t =4 s 时,v =40 m/s -10 m/s 2×4 s =0,D 正确.答案:

Dr. Aiken studied a number of couples who had been married for at least twenty-five years. Each couple provided four photographs—one photo of each partner at the time of their marriage and another photo to remove any clues. The photos were then displayed in groups: a random(随意的)grouping of the persons at the time of their marriage and another random grouping of the same persons who took photographs later. Some judges were asked to pick out the partners. They failed totally with the first group. Their judgments were no better than chance. But with the photos taken twenty-five or more years after the marriage, the judges were quite successful at deciding who was married to whom. They were particularly successful with the most happily-married couples.Dr. Aiken believes there are several reasons why couples grow alike. One reason has something to do with imitation. One person tends to copy or do the same as someone else without knowing it. He says human beings copy the expressions of the faces of their loved ones. Another possible reason, he says, is the common experience of the couples. There is a tendency for people who have the same life experience to change their faces in similar ways. For example, if a couple suffered a lot of sad experiences, their faces are likely to change in a similar way.56. The main purpose of the passage is to .A.tell how couples look like each otherB.show the life experience of husband and wifeC.explain why couples grow alikeD.describe the study on a number of married people57. The judges failed to .A.tell couples by looking at their photos taken when they got marriedB.tell happily-married couples from sadly-married couplesC.discover the difference of each partnerD.understand Dr. Aiken’s study58. The underlined sentence “Their judgments were .A. quite successfulB. based on factsC. only by luckD. totally wrong59. From the passage we can draw a conclusion that .A.happily-married couples are often richer than other couplesB.couples who look alike can live longerC.the influence between couples can be quite strongD.all couples have been proved to grow alikeBWhen Li Jinyu went back from Brazil after years of hard training, he seemed to see a new starting point in front of him. Li, a key player of Jian Li Bao Football Team, has a round and lovely face. When talking to people, he often says, “I’ve got a lot of dreams, and the biggest one is to help to develop our national football.”Li began to play football 17 years ago. In 1985 a football coach was looking for little players in a school. Li tried to win the coach’s favor. His father, a football fan, asked the coach to give his son another chance to ha ve a test. This time, the coach agreed to take Li as a player. Every day, his father would take him to the training school, and carry him back when the training was over, whether it was raining or shining. With the help of his coach, Liquickly grew into a good young player. He is said to have the sharpest mind on the playground among all Chinese football players.The only child of the family as he is, Li loves his parents as much as they love him. During the spare time of the training course or after a game, he has often called home to ask after his parents.Li also enjoys good relations with his fans. He has received many letters from across the country, but he said he felt sorry because he could not answer every letter. “However, I have taken good care of every letter from my fans. This is perhaps the best way to show my thanks,” he said.Now at the age of 24, Li likes to go shopping after days of hard training on the playground. He is also interested in bowling and tennis. Dreaming of becoming a first-class player, he is now working very hard on the road to success.60. When did Li begin to play football?A. At the ege of 13.B. At the age of 7.C. Before starting school.D. After leaving school.61.

At least 12,000 years ago, dogs became the first animals to be tamed(驯服). Today, these lovely animals can be found almost anywhere there are people to love and serve. About 49 million dogs live as pets in the United States, and 3 million live in Canada.Dogs vary greatly in size. The smallest dog is the Chihuahua. On the average, Chihuahua weighs only about 4 pounds(1. 8 kilograms)and stands about 5 inches(13 centimeters)high at the shoulders. The tallest dog is the Irish wolfhound, which may grow 34 inches(86 centimeters)in height. The St. Bernard ranks as the heaviest dog. It weighs as much as pounds(90 kilograms).Dogs belong to a small family of meat-eating animals that also includes wolves, coyotes(北美草原狼), foxes, and jackals(豺). Dogs look like these animals in body structure and behavior. The dingo of Australia and certain animals that live in other parts of the world are commonly called wild dogs.Some dogs do important work for people. Dogs are able and willing to learn a wide variety of tasks becausethey are clever and devoted(忠诚的)to their owners. Sharp watchdogs protect houses and businesses from thieves. Collies, sheepdogs, and some other dogs look after cattle. In some countries, dogs help farmers by pulling vegetables and other products to market in small carts.Dogs also use their keen senses to help people. A sharp sense of smell enables beagles and many other hunting dogs to follow wild animals. Police rely on the bloodhound’s sensitive(敏感的)nose to find criminals (罪犯)and lost people. Law enforcement officers also train German shepherds and other dogs. to smell drugs and hidden explosives(炸药). Guide dogs lead blind people. Other specially trained dogs serve as “ears” for deaf people.Medical researchers use thousands of dogs in experiments every year. In this way, dogs have helped scientists develop new lifesaving drugs and new surgical techniques(外科技术). However, some people believe that it is cruel to use dogs—as well as other animals—in laboratory experiments.69. The second paragraph mainly talks about the of dogs.A. weightB. heightC. sizeD. growth70. The underlined word “beagles” in the fifth paragraph is dogs’ .A. nameB. familyC. weightD. sense71. According to the passage, in how many ways can dogs help people?A. Six.B. Five.C. Four.D. Eight.72. What’s the main idea of the passage?A.Some dogs do important work for people.B.Dogs can do a lot of good to people.C.Dogs are different in many ways.D.Dog is a popular pet.EThe problem started when the family moved and Chris switched schools. He made friends with a new set of kids, some of whom used drugs. The first time Chris used cocaine(可卡因)was with friends at Larry’s house. Everyone pooled their money to buy a few grams of cocaine. Larry told them, “It’s safe as long as you don’t use it too often. It won’t turn you into an add ict(上瘾者)like other drugs. ”During the following year, the group tried crack along with cocaine. Chris bragged, “I can handle this material!”Larry agreed, “As long as you only take a little bit, you’ll be okay. ” He said he sold it to them “at cost” anddescribed(描述)it as “pure cocaine”.When one friend ended up in the hospital from an overdose(过量), Chris thought, “That’ll never happen to me. Since I’m mostly sniffing(smelling)the drug, I won’t have any problem. ”At 16, Chris dropped out of school. When his parents tried to change his mind, he left home without telling them where he was going. He lasted two weeks working at a pizza parlor(shop)before getting fired for stealing money. That’s when he started selling cocaine. “I’ll only do this until I get back on my feet,” he told himself.Chris’ family found him living alone in a run-down part of town. A school friend has called the family to tell them where he was. “It probably saved my life,” Chris says. “I was half-dead. ”To pay for Chris to enter a drug treatment center, his dad took a second job. Chris is grateful to getting treatment. Now he’s able to see colors again. In the depths of his addiction he saw everything in black and gray.73. Chris began to use cocaine .A.when his friend, Larry, persuaded him to do soB.because he wanted to try it only on his ownC.when all of his friends taught him how to use itD.because he liked it very much74. Which of the following is TRUE?A.Chris got crack and cocaine from Larry free of charge.rry sold crack and cocaine to Chris and some of his friends.C.It is safe to use a little cocaine.D.Chris used cocaine for half a year.75. From the last paragraph, we can learn that .A.Chris gets free treatmentB.Chris wants to thank his parents for paying for his treatmentC.Chris’ dad works hard in order to be richD.Chris has good eyesight in seeing colors第Ⅱ卷(一部分,共35分)第四部分:写作(共两节,满分35分)第一节:短文改错(共10小题; 每小题1分,满分10分)A family is sailing around the Pacific Ocean.
