双基限时练(十四)　Unit 5　Part Ⅱ
基 础 夯 实
Ⅰ.用所给动词的适当形式填空
1．He 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。
3．The 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。
4．Dina, ________ (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　Looking　look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。
6．At 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。
7．A 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　Throwing　throw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 she'd like that little doll on her bed.
答案与解析　Seeing　see这一动作由句子的主语“I”发出，故空格处须用现在分词。
10．He 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。
11．The 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。

答案与解析　
1．about　be concerned about sth.“担忧/关怀某事”。
2．was wiped　所给词在句中作谓语且依据句中时间状语last winter 可知动词应用一般过去时态，且wipe与其规律主语the forest 为被动关系，故空处填was wiped。

语 篇 提 能
Ⅲ.阅读理解
A
In Los Angeles, drivers spend sixty­one hours every year stuck in traffic. These drivers know all too well how bad the traffic can be. “There're too many cars, and you can't 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.“What's unique is that we use a lot of data that's currently become available including traffic data, weather data, and we analyze that so that we can predict what's 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.
1．What is unique about ClearPath?
A．It 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。
2．The underlined word “hits” in the fourth paragraph probably means ________.
A．have 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”。
3．What's Professor Shahabi's attitude toward his invention?
A．Disappointed. 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。
B

Every 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.“We've 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.
4．Hurricanes usually ________.
A．form off the coast of Africa and America
B. travel at 40 miles per hour and get its name
C. hit parts of the world in summer and autumn
D. 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。
5．The underlined word “evaporates” probably means ________.
A．turns hot B. gets lost
C. 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。
6．The speed of the biggest two hurricanes reaches about ________ per hour.
A．75 miles B. 95 miles
C. 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。
7．Which of the following about the information of a hurricane is the CORRECT order?
a．The ocean water evaporates and goes into the air.
b．Heat creates energy and causes winds to increase.
c．The vapor cools.
d．The ocean water is warm enough.
e．The vapor changes back into liquid.
f．This course gives out heat.
A．d－a－c－e－f－b B. a－b－c－f－d－e
C. a－d－e－b－c－f D. d－a－b－c－e－f
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。
