Question

【題目】 Answer the questions(根據(jù)短文內(nèi)容回答下列問題)

Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(裝置)which uses satellites(衛(wèi)星)to find the user's position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(計算)its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精確的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

【解析】

本文講述了GPS。GPS即全球定位系統(tǒng)，是一個小型收音機接收器。它看起來像一個手機。全球定位系統(tǒng)有三個部分。第一部分是接受者。第二部分是一組繞地球運行的衛(wèi)星。第三部分是一個地面站網(wǎng)絡。有些人認為在未來GPS將像移動系統(tǒng)一樣常見。

【1】句意：GPS能幫你找到你的位置，不是嗎?

根據(jù)“It is a device(裝置)which uses satellites(衛(wèi)星)to find the user's position(位置). ”，所以能找到位置，故答案為Yes, it can.

【2】句意：GPS是什么樣子的?

根據(jù)“It looks like a mobile phone”它看起來像一個手機，故答案為It looks like a mobile phone.

【3】句意：文中提到多少種東西里有GPS設備?

根據(jù)“It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats”有時它放在手表上或者電話上，我們還在汽車、飛機或船只上找到GPS設備，是5個，故答案為Five。

【4】句意：地面站有什么用途?

根據(jù)“They control the satellites and make sure they are working well. ”他們控制著衛(wèi)星，確保它們運轉(zhuǎn)良好，故答案為Ground stations control the satellites and make sure they are working well.

【5】句意：為什么有些人認為GPS設備在未來會很流行?

根據(jù)“They are becoming cheaper and more and more accurate. There are also new uses for the GPS”他們變得越來越便宜，越來越準確，GPS也有新的用途。故答案為Because they think GPS are becoming cheaper and more and more accurate. There are also new uses for the GPS.

【6】句意：作者寫這篇文章的目的是什么?

根據(jù)全文講述了GPS，包括它的樣子，用途，工作原理。所以作者的目的是介紹GPS，故答案為To introduce the GPS。
