Each Chinese family is now urged to have no more than one child. And the hope is to reach a zero population growth with the total number of births equaling the total number of deaths by the year 2000.
A major new study shows that the situation may be changing. A large and rapid drop in the world’s birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.

考点定位:简单机械2.如图所示,OAB为轻质杠杆,可绕支点O自由转动,在B端施加一个动力使杠杆在水平位置平衡,该杠杆()A.一定是省力杠杆B.一定是费力杠杆C.一定是等臂杠杆D.以上情况都有可能答案:D解析:杠杆根据动力臂与阻力臂的大小关系,可分为省力杠杆、费力杠杆和等臂杠杆;在本题中阻力和阻力臂的大小都是固定的,而动力和动力臂的大小不确定,由杠杆的平衡条件可知,动力与动力臂成反比,动力的方向不同,动力臂的大小就不同,所以动力臂可能大于、小于或等于阻力臂,所以杠杆的种类也不能确定,所以应选D。

考点定位:杠杆的分类3.2015年5月8日上午,我市中小学生足球联赛正式打响,这是我市重视足球运,提升校园足球水平的重要措施.关于足球,下列说法正确的是()A.静止在水平桌面上的足球对桌子的压力与桌子对足球的支持力是一对平衡力B.静止在水平桌面上的足球受到的重力与桌子对足球的支持力是一对平衡力C.忽略空气阻力,足球在空中上升的过程中重力势能转化为动能D.比赛中足球离开运动员在空中继续飞行是因为足球受到惯性力作用答案:B解析:静止在水平桌面上的足球对桌子的压力与桌子对足球的支持力作用在不同的物体上,是一对相互作用力,不是一对平衡力,故A错误;静止在水平桌面上的足球受到的重力与桌子对足球的支持力大小相等、方向相反、作用在同一直线上、作用在同一物体上,是一对平衡力,故B正确;忽略空气阻力,足球在空中上升的过程中,高度增加,速度减小,是动力转化为重力势能,故C错误;比赛中足球离开运动员在空中继续飞行是因为足球具有惯性,惯性不是力,所以不能说受到惯性力作用,故D错误;故应选B。

They do a lot to get you where you need to go.But sometimes, kids hhave problems with these important body parts. Their legs and feet might look different or might not work exactly the way they should. The good news is that these problems usually aren’t serious. They either go away on their own or the kids learns to handle them by using stuff like special shoe inserts.PIGEON TOES(内八字脚) pigeon toes, or inwardly turning toes, is a common foot condition in kods. It occurs when the front of the foot is turned inward, facing the other foot.Boys and girls both experience pigeon toes. Most kids’s feet straighten naturally without any medical treatment.BOW LEGS(O型腿)When someone stands with the feet and ankles (脚踝) together but the knees widely apart , we call that being bow-kegged. Many babies are born bow-legged because their legs were folded tightly across their belly while they were growing inside thiet mom. Bow legs usually straighten once babies with thid conditions start to walk and their legs bear weighrt. By age 3, most kids grow out of this condition. KNOCK KNEES (X型腿) Knock knees is a condition where the legs curve in at thr knees so much that the ankles are separated. Lots of kids become knock-kneed between the age of 3 and 5. But around age 6, the body begins to straighten naturally, and within a few years most kids can stand with their knees and ankles touching at the same time. FLAT FEET Stand sideways in front of a mirror. Rise up on your toes. Can you see the arch (curve) in the bottom of your feet? Most of us have some sort of arch on the bottom of the feet between our toees and heel.Someone who doesn’t have this curve might have flexoble flat feet. That means more of the person’s foot surface is in contact with the ground.In a typical foot, the arch part wouldn’t touch the ground.Most babies are born with almost no arch in their feet. Within 2 to 3 years, after kids have been walking fo a whil, the arch develops.Wearing the right kind of shoes-ones that are flexible, not stiff-helps kids’ feet develop the way they should.About 1 in 7 kids never develop a full arch. Very rarely, this requires surgery (手术) . Some kids might wear arch supports if their feet hurt. But most of the time,flat feet don’t cause pain or problems. In other words, if your feet are flat, they are fine!27.( )The author believes that the problem that most kids have with their legs and feetare serious. 28.( )Girls need some medical treatment to correct their pigeon toes while boys don’t.29.( )By the age of 3, most kods with bow-legged problem usually straighten naturallywithout special treatment.30.( )According to the author, about 86% of kids can develop a full arch.31.( )If your feet are flat, it means that they tend to hurtSection B Reading in Depth(2×10=20 points)Directions:There are 3 passages in this section,please choose the best answer to each of the questions.“A rescue team guided by a survivor was dispatched into stormy Indonesian seas Tuesday in search of dozens of people said to be still drifting alive after a ferry capsized (倾覆) with more than 250 on board,” officials said.“The survivor, pulled from the water earlier Tuesday by fishermen, told authorities another 40 people escaped the boat before it sank in cyclone and are still at sea,”said Sutriani, a port official in Majene, Sulawesi.Air and sea patrols resumed at sunrise, two days after the 700-ton (635-metric toe) Teratai Prima disappeared with at least 250 passengers and 17 crew on board.So far at least 34 people, including the captain, have been rescued and one body recovered. Hopes had been fading that anyone else would be rescued because of the continuing bad weather caused by Cyclone Charlotte.“But a search party was deployed on a police boat with a survivor and fishermen acting as guides,” said Sutriani. It is customary in Indonesia to use only one name.“A group of around 40 men is clinging to a floating platform used by fishermen,” said Lt.Col. Zakarya, a rescue coordinator in Majene, citing accounts given by fishermen. “We have to rescue them immediately,” he said. “We have taken the fishermen to show us the way.”Transport Minister Jusman Syafi’I Djamal said earlier Tuesday an investigation was under way to determine why the captain apparently ignored warnings not to travel into the Makassar Strait.The government will compensate families 2,400,dollars, or roughly two times an average annual salary in impoverished (赤贫的) Indonesia, for each victim of the accident.Most of those rescued thus far were picked up by fishing and cargo ships within hours of the sinking and taken to nearby ports. They told of a churning sea and relentless waves before the ferry suddenly submerged in the dark.Baco, a psssenger, was fast asleep in the ship’s lower deck when sea water rushed in and swept away about 20 children whihin seconds as he looked on helplessly.“They were just sucked away,” he said, sobbing as he recalled how the boat suddenly capsized before dawn Sunday.Baco, a father of five who was taking the ferry to Borneo to look for a job with an oilcompany, described the sudden horror of the scene.“Many people were still sleeping when the water came to the second deck just above the engine room,” said Baco,40.“Around20 little children were taken by the sea. I could do nothing,” he said, weeping as he described the screams of the drowning.Baco clung to a piece of plastic foam and drifted for five hours before joining another man on a life raft. They were later picked up by fishermen.The Teratai Prima, which radioed that it was in trouble just before dawn Sunday, capsized about 30 miles (50 kilometers) off the coast of western Sulawesi. It was headed for Samarinda on the Indonesia side of Borneo.Boats are a major form of transportation in Indonesia, the world’s largest archipelago with more than 17,000 islands. Poor enforcement of safety regulations and overcrowding cause accidents that claim hundereds of lives each year.In December 2006, a crowded Indonesian ferry broke apart and sank in the Java Sea during a violent storm, killing more than 400 people.32.What caused the accident?A.A cyclone.B. A typhoon.C.Heavy rainD.A crash.33.Who saved the survivor that guided the rescue team?A.The search party.B.The fishermen.C. A passengerD.The captain.34.How many people were said to have escaped the boat and be still drifting at sea?A.250.B.34.C.40.D.24.35.About how many children were swept away by the sea water?A.20B.40.C.34.D.17.36.At least____people were on board when the boat sank.A.267B.260C.40D.2,503Many years ago, my dad was diagnosed with a terminal heart condition. He was put on permanent disability and was unable to work at a steady job. He would be fine for quite a while, but would then fall suddenly ill and have to be admitted to the hospital.He wanted to do something to keep himself busy, so he decided to volunteer at the local children’s hospital. My dad loves kids, so it was the perfect job for him. He ended up working with terminally and critically ill children. He would talk to them and play with them and do arts and craftts with them. Sometimes, he would lose on of his kids. Incertain instances, he would tell the grieving Prents of these children that he would soon be with their children in heaven and that he would take care of them until they got there. He would also ask the parents if there was a message they would like to send with him for theit child.My dad’s assurances seemed to help parents with their grieving. One of his kids was a girl who had been admitted with a rare disease that paralyzed (使瘫痪) her from the neck down. I don't know the name of the disease or what the prognosis (病情预断) usually is, but I do know that it was very sad for a girl around eight or nine years old. She couldn’t do anything, and she was very depressed. My dad decided to try to help her. He started visiting her in her room, bringing paints,brushes and paper He stood the paper up against a backing, put the paintbrush in his mouth anf began to paint. He didn’t use his hands at all. Only his head would move. He would visit her whenever he could and paint for her. All the while he would tell her , “See, you can do anything you set your mind to.”Eventually, she began to paint using her mouth, and she and my dad became friends. Soon after, the little girl was discharged beause the doctors felt there was nothing else they could do for her. My dad also left the children’s hospital for a little while because he became ill, Sometime later, after my dad had recovered and returned to work he was at the volunteer counter in the lobby of the hospital. He noticed the front doors open. In came the little girl who had been paralyzed; only this time she was walking. She ran straight over to my dad and hugged him really tight. She gave my dad a picture sh had done using her hands. At the bottom it read: Thank you for helping me walk.My dad would cry every time he told us this story and so would we. He would say sometimes love is more powerful than doctors, and my dad-who died just a few months after the little girl gave him the picyure-loved every single child in that hospital.37.Why did the author’s dad volunteer at the local children’s hospital?A.Because he could help the kids with their illness.B.Because he dicided to do something to keep himself busy.C.Because he could do arts and crafts for the kids.D.Because he could help the kid’s parents.38.What did the author’s dad do when he lost one of his kids in the hospital?A.He would ask the parents if they needed help.B.He would send a message to the parentsC.He would talk to the grieving parents and comfort themD.He would take care of the grieving parents39.In the third paragraph, the author’s dad helped a paralyzed girl by_____?A.visiting herB.bringing paints to herC.talking to herD.visiting and painting for her40.The word “discharged” (Line 2, Para.4) most probably means__________.A.sent back homeB.recoveredC.abandonedunched41.Which of the following is true?A.The author’s dad was a careless worker.B.The author’s dad had worked with the sick kids ever since he was young.C.The author’s dad was a kind-hearted man.D.The author’s dad was more powerful than doctors.Part ⅣTranslationSection A (1×5=5points)Direction: Translat the following sentences into Chinese.42.As she was about to walk into the elevator she noticed two men alerady aboard.43.The harbormaster waved his arms and yelled for the young man to stop, that there wasa storm coming.44.Do not point fingers at polictical or historical figures.45.I was curious to see if this was a new service the airport had put in place.46.Some worry that all this debt forces grads to forsake exciting but low-paying jobs infavor of dreary but well-paying jobs.Section B(2×5=10 points)Direction: Complete the sentences by translating into English the Chinese given in brackets.47.They felt that their leader _______________________________________(在他们需要的时候离弃了他们).48.__________________________________(不管你给不给小费),she just served youwarm-heartedly with smiles.49.________________________________________(他们没有取笑他), they becametouchingly protective.50.Although the cost was reduced, __________________________________(但还是没有用).51.He looked at the funny-looking man,_________________________________(咬着嘴唇强忍着不笑出声).Part ⅤCloze (1×20=20 points)Directions: There are 20 blanks in the following passage.
