二、勤练高考题型，多练自能生巧 Ⅰ.阅读理解

Satellites are an important part of our ordinary lives.For example, the information for weather forecasts is sent by satellite.Some satellites have cameras which take photographs of the Earth to show how clouds are moving.Satellites are also used to connect our international phone calls.

Computer connections of the World Wide Web and Internet also use satellites.Many of our TV programmes come to us through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.

We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometres above the equator (赤道)．Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometres an hour — exactly the same speed that the earth rotates (转动)．A satellite must orbit the Earth with its antennae (天线) facing the earth.Sometimes, it moves away from its orbit, so there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.

Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 10～12 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to the Earth to be repaired.Often, very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear power and they can crash into each other.

语篇解读：本文是一篇科普说明文。文章对各种卫星的用途、卫星工作的状态以及人们对已损坏卫星的处理办法进行了解释说明。

1．Which of the following is NOT done by satellites according to the passage? A．Sending information for weather forecasts. B．Taking photographs of the Earth. C．Sending TV pictures.

D．Providing food for airplane pilots. 解析：选D 细节理解题。根据第一段和第三段首句不难看出，卫星可以传递天气预报信息、拍摄地球照片、传递电视图片等，但是没说为飞行员提供食物，所以选择D项。 2．Why does the satellite move around the world at the same speed as the Earth rotates? A．In order to take photographs.

B．In order to stay in a certain position in the orbit. C．In order to move away from its orbit. D．In order to send television pictures.

解析：选B 细节理解题。根据第三段内容可以看出，卫星之所以用和地球自转相同的速度绕地球旋转，是为了保持在一定位置上。显然B项正确。

3．What does the underlined word “This” in the 3rd paragraph refer to? A．A satellite. B．A little rocket.

C．A satellite seems to stay in the same place in the sky. D．The satellite puts the rockets in the right position. 解析：选C 代词指代题。this在此替代前文的“Sometimes we can see a satellite in the sky and it seems to stay in the same place.”故选C项。

A．A satellite usually works for about 10～12 years.

B．Every time a satellite gets broken, it is brought back to the Earth to be repaired. C．A broken satellite is never left in space.

语篇解读：作者在文中告诉我们如何选择朋友以及如何对待朋友。

1．It 空格处为形式主语，真正的主语是空格后的不定式短语，故空格处填代词It。

2．who/that 先行词person指人，关系词在从句中作主语，故用who/that引导定语从句。 3．valuable 空格处在句中作表语，由此结合语境可知，应填形容词valuable。

4．as 根据句意“我们应选择那些有优秀品质的人作为朋友”可知，空格处填介词as。 5．making avoid后应接动词-ing形式作宾语。

6．be trusted 主语是动作的承受者，故空格处应用被动语态。 7．others 根据句意 …… 此处隐藏：5647字，全部文档内容请下载后查看。喜欢就下载吧 ……
