Each passage is followed by several questions or unfinished statements.Choose the one that fits best according to the information given in the passage.ASchoolgirls have been wearing such short skirts at a Staffordshire school that they’ve beenordered to wear pants instead.All skirts will be banned from September at Paget High School in Branston, Burton upon Trent.Tight-fitting trousers will also be forbidden and Muslim head-dresses will have to be “school blue”color.Head teacher Don Smith said: “One of the big issues for us at the school has been the number of girls who have been wearing inappropriately short skirts.This has been an area of particular concern at a time when there has been a lot of material nationally about the sexualization of young people.”Mr Smith said it would’t be practical to check the length of girls’ skirts and said a blanket ban would be easier for staff to enforce.He said: “We did not want to arrive at a situation where we were telling girls their skirts could only be a certain number of centimeters above or below the knee.”The head teacher said they sought opinions from pupils, parents and other teachers before the uniform rules were changed.The new clothing policy has been explained in a letter sent to parents of the school”s 1,000 pupils and will come into force after the summer holiday.The school also wants pupils to wear clip-on ties instead of traditional neckwear.This rule will be phased(分阶段实施) in over the next year and support will be given to parents unable to afford the new tie.The new uniform regime has not been well received by everyone, however.One parent, whose teenage daughter attends the school, said: “I completely agree some girls were wearing skirts that were too short. However, I think girls should be allowed to be feminine(女性气质的).Other schools manage to let girls wear skirts while making sure they are not inappropriately dressed. I don’t see why Paget can’t do the same.”56.What is the main idea of the passage?A.Paget High school bans all skirts.B.Tight-fitting trousers will be forbidden.C.Muslin head-dress will be forbidden.D.School girls are ordered to wear uniforms.57.Which of the following is TRUE according to the passage?A.Girls can wear skirts which are long enough.B.The school will offer uniforms for free.C.Girls are allowed to wear skirts that cover their knees.D.An overall ban of girls will be carried out.58.According to Paragraph 2,the major problem Paget High School is faced with is that ______.A.pupils have to wear clip-on tiesB.many girls are wearing skirts too shortC.many parents are unable to buy school uniformsD.the new uniform system isn’t accepted by all students59.When the new uniform policy is to be put into force,what is the reaction of girls and theirparents?A.They are all not satisfier with it.B.They can’t agree to it more.C.They are supportive to the policy.D.No parents insist on their daughters wearing short skirts.60.What will the new clothing policy include?A.Girls can wear short skirts to look sexy.B.New ties will be given to some girls for free.C.The uniform rules will be changed if necessary.D.Girls’ wearing will be checked regularly.BThere is an exercise method,it was made to stretch muscles and improve strength and balance,soon it is becoming popular in the United States. Here’s more about Gyrotonics and the man who invented this special form of exercise.Gyrotonics is a kind of exercise that combines the movements of dancing and swimming with the mental and physical practice called yoga .It helps lengthen muscles, improve balance, and exercise the joints, the parts of the body where bones join each other.A Hungarian dancer named Juliu Horvath developed this special form of exercise .After he was injured in a dancing accident, Mr. Horvath studied yoga intensely. In the 1980s, he developed a new exercise method and combined it with yoga to stre ngthen dancers’muscles.According to Mr Horvath, his method is based on the octopus, the monkey and the cat. He says these animals have few restrictions. They can move in any direction with control and strength. He designed Gyrotonic movements to help the human body move more freely.A special machine made of wood and weights helps guide the body through the many Gyrotonics exercises. You sit or lie on a flat board. You put your legs or hands through special cloth handles attached to a line with weights. With the tension created by the weights, you must try to move through the exercise.Seven kinds of backbone movements form the base of Gyrotonics. For example, you can stretch your back to the left and right or forwards and backwards. While moving your back, you can also work on arm or leg motions. These movements must be done in a smooth way. Often the motions are circular.When Juliu Horvath first developed Gyrotonics, he was the only teacher. Since then , he has taught almost 70 master trainers. Now, there are more than 800 official schools in the world where you can learn Gyrotonics.61. This passage mainly focuses on .A.

His wish to be a Gyrotonics trainer.63. What do you think inspired Horvath in developing Gyrotonics?A. His experience in dancing.B. His use of a special machine.C. The movements of some animals.D. The ideas from many trainers.64. lf you intend to strengthen your body through Gyrotonics, you have to .A. have a strong bodyB. turn to HorvathC. watch how animals moveD. buy the machine mentioned65. What do we learn from the passage?A. Many Americans have improved their health through Gyrotonics.B. In a way, Gyrotonics is an exercise that improves yoga.C.

They started early in London. The headman was Auguste Gaudron, and the other two men were Tannar and Maitland. They had a big balloon, and they were ready for a long way.Soon they heard the sea below them. They were carrying the usual rope , and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water. Or it could be empty. So they were able to cha nge its weight. They were also carrying some bags of sand.After the sun rose, the balloon went higher. It went up to 3,000 meters, and the air was very cold. The water in the balloon became ice. Snow fell past the men’s basket, and they could see more snow on the ground. There was also some snow on the balloon, and that made it very heavy. It began to go down towards the ground. The men tried to throw out some more sand; but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling; so they had to drop some whole bags of sand. One of them fell on an icy lake below and made a black hole in the ice.At last they pulled the box into the basket. It was still snowing; so they climbed to get away from the snow. They rose to 5,100 meters! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely.

Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.By teaching your children fire safety you can make sure they know what to do when a house fire occurs. Making sure that your children know exactly what is required of them cuts down on the chaos of the emergency situation and helps keep your family safe and secure.All children should know about important fire safety procedures such as the need to stay low to the ground in a smoky room, which keeps them from inhaling smoke, as smoke always rises towards the ceiling. Also tell them that they can put a damp towel or a piece of clothing over their faces and breathe in through it in order to cut down on the effects of smoke inhalation even more. In addition, make sure your children know how to correctly stop, drop, and roll when their clothes catch fire. Because it results in lack of oxygen, which puts out the flames. Also your children should know to touch door handles before opening the door to see if they are hot. If they are, it means that there's a fire in the next room, and they should leave the door closed and find another route out of the house.Make sure your children understand that they should never play with lighters or matches. Many children are fascinated by lighters and matches and want to experiment with lighting things on fire to see what happe ns. Hide lighters and matches in some places your children can’t reach.Do regular fire drills to practice your evacuation plan. Make sure everyone knows all the possible exits of the house and that all members of your family know your evacuation plan well enough so that they don't have to waste time thinking if a fire starts. Quick, determined response to a fire will save your family members' lives.Teaching Fire Safety to Children71. for teachingchildren fire safetyChildren should know what to do in case of a house fireIt can help children to 72 of the emergency situation.To teach children 73 Stay low to the ground and 74 with damp towels or clothing.Correctly stop ,drop and roll to put out the fire on the 75 .Don’t open the door s with 76To forbid children from playing with lighters and matches It’s dangerous to77 with lighting things on fire.

Answer the questions according to the information given in the passage.As a young man, Al was a skilled artist, a potter. He had a wife and two fine sons. One night, his older son developed a severe stomachache. Thinking it was only some common intestinal(肠的)disorder, neither Al nor his wife took the condition very seriously. But the disease was actually acute appendicitis (阑尾炎), and the boy died suddenly that night.Knowing the death could have been prevented if he had only realized the seriousness of the situation, Al's emotional health declined under the enormous burden of his guilt. To make matters worse his wife left him a short time later, leaving him alone with his six-year-old younger son. The hurt and pain of the two situations were more than Al could handle, and he became an alcoholic.As the alcoholism progressed, Al began to lose everything he possessed — his home, his land, his art objects, everything. Eventually Al died alone in a San Francisco motel room.When I heard of Al's death, I thought, “What a complete failure!” “What a totally wasted life”.As time went by, I began to re-evaluate my earlier harsh judgment. You see, I knew Al's now adult son, Ernie. He is one of the kindest, most caring, most loving men I have ever known. I watched Ernie with his children and saw the free flow of love between them. I knew that kindness and caring had to come from somewhere.I hadn't heard Ernie talk much about his father. One day I worked up my courage to ask him. "I'm really puzzled by something," I said. "I know your father was basically the only one to raise you. What on earth did he do so that you became such a special person?"Ernie sat quietly and reflected for a few moments. Then he said, "From my earliest memories as a child until I left home at 18, Al came into my room every night, gave me a kiss and said, 'I love you, son.'"Tears came to my eyes as I realized what a fool I had been to judge Al as a failure. He had not left any material possessions behind, but he had been a kind loving father, and he left behind one of the finest, most giving man I have ever known.1. Why was Al in guilt?

从几内亚开始的新一轮埃博拉疫情正呈加速蔓延之势,目前已报告1323个确诊或疑似病例,其中729人丧生。
有国际医疗组织指出,此轮疫情正面临进一步“失控”的境地。
在历史上,此次埃博拉暴发是最严重的一次,但一直没有引起关注。
可能的原因之一是,埃博拉一直没有走出非洲。
尽管一些专家认为,埃博拉只会在非洲局部暴发流行,像SARS一样产生全球性感染的可能性几乎没有,但是,埃博拉走出非洲也许只是早晚的事。
认为埃博拉不会在全世界流行的理由是,埃博拉感染的渠道是直接接触感染者的血液、精液、分泌物及其他体液,或者接触被感染对象的尸体。
迄今尚未有确认通过空气传播的病例,因此,即使搭乘飞机或火车等公共交通工具时遇到埃博拉感染者,感染的概率也十分低。
只有非洲当地人才会“谈埃色变”,因为埃博拉是迄今死亡率最高的疾病之一,死亡率在50%-90%之间。
由于埃博拉的死亡率极高,世界卫生组织将其划归为病毒第四级,即在实验室里进行分离、实验微生物组织结构时安全隔离分级的最高等级。
第四级病毒会造成致命疾病,并且在绝大多数的情况下是不可救治的,死亡率最高。
除了埃博拉,第四级病毒还有艾滋病病毒(HIV)和拉沙(lassa)病毒等。
然而,在病毒和疫情的凶险上,埃博拉可能是首屈一指的。
由于埃博拉病毒在体内侵蚀和毁坏各种器官,就像绞肉机一样绞碎各种组织器官,使得病人不断把坏死的组织从口中吐出,当无数病人都因体内广泛性内出血而口吐鲜血和坏死的组织,并且七窍流血、脑部受损而挣扎着死亡时,连空气中都散发着血腥味和浓烈的臭味。
同为第四级病毒的HIV只是潜伏在人体的免疫T细胞中慢慢发作,并毁坏T细胞的免疫功能,虽然不能治愈,但HIV感染者和艾滋病病人可以生存较长时间,不会马上死亡,而且如果终生服药,艾滋病病人还可以达到常人一样的寿命(可活到70岁),这是艾滋病与埃博拉的天壤之别。

With the car full of flowerswe were going home. On our way back my wife noticed a cupboard(橱柜) outside a furniture shop. It was tall and narrow. “Buy it,” my wife said at once. “We’ll carry it home on the roof rack(行李架). I’ve always wanted one like that.”What could I do? Ten minutes later I was 20 pounds poorer; and the cupboard, was tied on to the roof rack. It was six inches long, eighteen inches square and quite heavy.In the gathering darkness I drove slowly. Other drivers seemed unusually polite that evening. The police even stopped the traffic to let us through. Carrying furniture was a good idea.After a time my wife said, “There’s a long line of cars behind. Why don’t they overtake(超车)?”In fact a police car did overtake. The two officers inside looked at us seriously as they passed. But then, with great kindness, they led us through the rush-hour traffic. The police car stopped at our village church. One of the officers came to me.“Right, sir,” he said, “Do you need any more help?”I was a bit puzzled. “Thanks, officer,” I said, “Your have been very kind.I live just on the road.”He was staring at our car; first at the flowers, then at the cupboard. “Well, well,” he said, laughing.“It’s a cupboard you’ve got there! We thought it was, something else.”My wife began to laugh. Then the truth hit me like a stone between the eyes.I smiled at the officer. “Yes, it’s a cupboard, but thanks again.” I drove home as fast I could.25.

Discover your own thoughts and feelings. Put what you think and feel into words, say, write a composition or a letter. You can then send your ideas and feelings to others. Sometimes writing a song or a poem can help you do this.Are you pleased that your father had offered to take you out for a holiday? Express your thankfulness to him by giving him a hug. Do you feel proud because a friend of yours won in a game? Share your pride by telling him how much you are proud of him. These are good feelings that you would like to share with others.Learning to express bad feelings is important, too. For example, you and your friend have disagreem ent on a certain point. You feel very unhappy about it. It’s wise to tell your friend what you think about the matter and tell him that it’s important that you two should reach an agreement because you need the support from a friend like him. If you have too many unexpressed feelings, they can affect both your physical and mental health.29.Which of the following statements is NOT true?A. Learn to communicate with yourself first.B.

Texting affects learning and performing on tests, a new study finds. So a Montana teen, Colter Norick, 17, and his 16-year-old brother Colin decided to test that.They asked 47 classmates to take part in a two-part experiment. The goal was to test how well these students understood written material. Each one had to read a paragraph or two about a certain topic, then answer questions about it.In the first part, the participants(参与者) had 15 minutes to understand and then answer questions about six readings. Throughout this test, they met no distractions(分散精力).During a new set of readings, the brothers sent messages to the participants’cell phones every 90 seconds. In each message, there were questions that required a reply.Participants should have scored better on the second test because it was easier. In fact, they scored worse when distracted by messages. Only a few students scored as well when replying to messages as they did when undistracted. But importantly, nobody performed better during the texting part.The brothers presented details of their findings at the International Science and Engineering Fair. Boys and girls scored equally poorly while texting, the brothers noticed. Older participants didn’t do any better than younger ones. And it didn’t matter if a student thought he was good at multitasking(多任务处理). On average, the brothers found that even students who were confident of their abilities did just as poorly while texting. Surprisingly, even though the students remembered less of what they read while texting, most of them answered questions in messages perfectly.“Our teacher are very happy to see these results,”says Colter. The teen’s new data strongly support their teachers’ opinion that texting while studying is a serious distraction.33.What did Colter and Colin want to test?A.Cell phone use and texting are more common.B.Teens should avoid cell phone use and texting.C.Texting affects students’ performance on tests.D.The effect of texting differs from person to person.34.The brothers’ findings were related to participants’ _________.A.ageB.qualityC.reading abilityD.reading speed35.From the results of the experiment, we can find_________.A.boys were better at multitasking than girlsB.the easier the tests were, the more mistakes were madeC.nobody did good job in the two-part experimentD.some students’ test results were not affected by texting.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,选项中有一项为多余选项。
