双基限时练(十四)Unit 5Part 基 础 夯 实.用所给动词的适当形式填空1He hurried to the booking office only _ (tell) that all the tickets had been sold out.答案与解析to be told句意：他匆忙赶到售票处，结果被告知全部的票都卖完了。英语中的only后接to do形式表示意想不到的结果；另外，动词tell与主语he之间是被动关系，所以要用动词不定式的被动形式。2_ (approach) the city centre, we saw a stone statue of about 10 metres in height.答案与解析Approaching句意：靠近城市中心时，我们观察一座大约10米高的石头雕像。approach与其规律主语we是主动关系，且与动作saw几乎同时发生。由于approach与we是主动关系，故用现在分词。3The lady walked around the shops, _ (keep) an eye out for bargains.答案与解析keeping现在分词短语作伴随状语，表示与主句谓语动词的动作同时发生。4Dina, _ (struggle) for months to find a job as a waitress, finally took a position at a local advertising agency.答案与解析having struggled现在分词短语的完成式作状语，表示该动作在主句谓语动词之前发生。5_ (look) at my classmates faces, I read the same excitement in their eyes.答案与解析Lookinglook与其规律主语I为主动关系，故用现在分词短语作伴随状语。6At the age of 29, Dave was a worker, _ (live) in a small apartment near Boston and _ (wonder) what to do about his future.答案与解析living; wondering句意：29岁的大卫，是一个工人，住在波士顿四周的一间小公寓里，对于他的将来不知怎么办。现在分词作定语修饰a worker, and为并列连词，连接相同的成分。7A small plane crashed into a hillside five miles east of the city, _ (kill) all four people on board.答案与解析killing所填词在句中为非谓语动词作状语，应用现在分词短语作结果状语。8_ (throw) their hats into the air, the fans of the winning team let out loud shouts of victory.答案与解析Throwingthrow与句子主语the fans之间为主谓关系，故用现在分词作状语。9_ (see) that she was going to sleep, I asked if shed like that little doll on her bed.答案与解析Seeingsee这一动作由句子的主语“I”发出，故空格处须用现在分词。10He was busy writing a story, only _ (stop) once in a while to smoke a cigarette.答案与解析stopping句意：他在忙着写一个故事，只是间或停下来抽支烟。此处应为现在分词短语作伴随状语，表示与write伴随的动作。11The glass doors have taken the place of the wooden ones at the entrance, _ (let) in the natural light during the day.答案与解析letting句意：在入口处，玻璃门已取代了木门，这样白天自然光就可以照进来了。据句意用letting现在分词作结果状语。.语法填空阅读下面材料，在空白处填入适当的内容(不多于3个单词)或括号内单词的正确形式。Sarah: Welcome to the program.

These drivers know all too well how bad the traffic can be. “Therere too many cars, and you cant move around a lot.”Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometres from his office at the University of Southern California, in Los Angeles. He is always late even with the help of a navigation (导航) system.He decided to develop a program called ClearPath for that. He says his program uses historical data to predict traffic conditions even before the driver leaves the house.“Whats unique is that we use a lot of data thats currently become available including traffic data, weather data, and we analyze that so that we can predict whats going to happen in front of you when you leave home.”Professor Shahabi says his system does more than just respond to current traffic conditions. With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give the fastest route. It looks at the entire road network, including surface streets as well as highways, before the driver hits the road. Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.“I always thought that Los Angeles had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this. ”Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple.1What is unique about ClearPath?AIt can use a lot of information all over the world.B. It can ensure that you will never be late for work.C. It helps drivers see clearly what happens on the road.D. It helps drivers know the road conditions ahead of time. 答案与解析D细节理解题。依据文章第三段其次句可知他的创造可以让司机提前知道路况信息。2The underlined word “hits” in the fourth paragraph probably means _.Ahave an accident B. get to C. turn left or right D. collect traffic data答案与解析B词义猜想题。依据画线词所在句前后的信息可知画线词意为get to “到达”。3Whats Professor Shahabis attitude toward his invention?ADisappointed. B. Proud. C. Optimistic. D. Worried.答案与解析C推理推断题。依据文章最终两段可知沙哈比教授认为洛杉矶和上海等大城市会很快用上他的创造，故他对自己的创造很乐观。BEvery year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict how, when, and where big storms will happen. The more exact scientists warnings are, the better people can prepare for the storms.Predictions are improving.“Weve got better over the years, especially the last few years，” says Phil Klotzbach, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just fight，” Klotzbach says.First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor(水蒸气) cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.If wind speeds reach 40 miles per hour, the system is called a “tropical storm”， and it gets a name. At 75 miles per hour, it becomes a hurricane.Hurricanes that hit the US start when a thunderstorm forms off the coast of Africa. Storms also develop over tropical waters in other parts of the world.On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or higher.The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.4Hurricanes usually _.Aform off the coast of Africa and AmericaB. travel at 40 miles per hour and get its nameC. hit parts of the world in summer and autumnD. cause sea winds to rise and blow over the sea答案与解析C细节理解题。由短文最终一段可知飓风来临的时间多为6月至11月，故选C项。5The underlined word “evaporates” probably means _.Aturns hot B. gets lostC. begins to move D. changes into gas答案与解析D词义猜想题。依据上下文，海水变热形成水蒸气，上升到空气中，随后变冷再分散成液态。由此推断，这里应是“变成水蒸气(气体)”的意思，故选D项。6The speed of the biggest two hurricanes reaches about _ per hour.A75 miles B. 95 milesC. 110 miles D. 115 miles答案与解析D细节理解题。短文倒数其次段结尾句给出最大的两个飓风时速为115英里或以上。故选D项。7Which of the following about the information of a hurricane is the CORRECT order?aThe ocean water evaporates and goes into the air.bHeat creates energy and causes winds to increase.cThe vapor cools.dThe ocean water is warm enough.eThe vapor changes back into liquid.fThis course gives out heat.Adacefb B. abcfdeC. adebcf D. dabcef答案与解析A细节理解题。飓风形成：海水变暖变成水蒸气，在上升的过程中遇冷分散成液体，在此过程中放热，加速了风的形成。风速达40英里每小时时形成热带暴风雨，75英里每小时时形成飓风。故选A项。
