2014年6月大学英语六级全真模拟题及答案(第八套)_第5页

　　Directions: In this part there is a short passage with five questions or incomplete statements.Read the passage carefully.Then answer the questions or complete the statements in less than 10 words.

　　Have you ever been asked to take a polygraph test for a job?A polygraph,also called a lie detector,is a device that is used to find out if someone is telling a lie.It is based on the belief that lying causes certain physical reactions.These reactions,which include a change in blood pressure and pulse rate,are measured by　the polygraph.?

　　Lie detector tests are often used in court and in the workplace.However,a law that went effect in December 1988 limits the ways that employers can use these tests.Employers can no longer use them to screen(审查) people who are applying for　jobs.The only exception is for those who want government jobs as security guards or drug handlers.Also,managers can no longer ask workers to take such tests unless there is reasonable suspicion that the worker has stolen or damaged property.This will curb tests for suspected offenses,such as drug use or sexual harassment,and for workers who were merely in the area of a theft.Bosses who request lie detector tests will have to tell workers why they are suspected of an offense.

　　Also,they may not ask questions that degrade workers,such as questions about their sex lives.?

　　In any case,according to the new law,the test is now voluntary:You can't be fired for refusing to take it.If you have been forced to take a polygraph test,or if　you are not being given a promotion because you have refused to take the test,you can sue the company or file a complaint with the Department of Labor.The Department of Labor can fine employers up to $10,000.
