Unit 4Body language说明文(2020;2020上海卷C篇)“Get your hands off me, I have been stolen，” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.The program allows users to display alerts on the missing computers screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version(版本) of the software, users can also send a spoken message.The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, You are being tracked. I am right at your door，” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.In the latest version, people can add a spoken message. For example, the laptops speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.If a thief accesses the Internet with the stolen laptop, Retriever will collect Information on the Internet service provider in use, so that the police can be alerted to its location.Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.Other security software allows users to erase data remotely or lock down the computer.72The expression “to give the thief a piece of their mind” can be understood as “_”Ato give the thief an alert mindBto express the owners anger to the thiefCto remind the thief of this conscienceDto make the thief give up his mind73Different from other security software, Retriever can _.Arecord the stealing process Bhelp recognize the lost laptopClock down the computer remotely Dsend a spoken message74One function of the program is that it allows the owner to _ at a distance.Achange some access details for switching on the laptopBturn on the laptop by using the original passwordCoperate the laptop by means of an alternative passwordDerase the information kept in the stolen laptop75Which of the following can best summarize the main idea of the passage?AWith no Retriever, thousands of laptops are stolen every year.BA new software provides a means to reduce laptop theft.CRetriever has helped to find thieves and lost computers.DA new program offers a communication platform with the thief.【答案解析】72选择B。根据上下文正确理解词语和句子。73选择D。由第二段第一句The program allows users to display alerts on the missing computers screen and even to set a spoken message.可得知。74选择A。由第二段第二句话.but t
