四六级考试六级每日一练(2018/5/2)
1题: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 th
at 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 harassm
ent,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.
Questions:
71. What is the passage mainly about?
72. How does the polygraph work?
73. The law of December,1988 prohibits employers from examing people who apply for jobs except ____
74. Nowadays the bosses can ask the workers to take the polygraph tests only

75. Under the new law,if a boss forces his worker to take a polygraph test,w
hat punishment will he get?

7、8、9、10、11题:Heroin addictions today is found chiefly among young men of minority groups in ghetto(犹太人区)areas.Of the more than 60,000 known addicts,more than half live in New York State.Most of them live in New York City.Recent figures show that more than half of the addicts are under 30 years of age.
Narcotic addiction in the United States is not limted to heroin users.Some middle-aged and older people who take narcotic drugs regularly to relieve pain can also become addicted.So do some people who can get drugs easily,such as doctors,nurses,and pharmacists.Studies show that this type of addict has personality and emotional problems very similar to those of other regular narcotic users.
Many addicts admit that getting a continued supply is the main object of their lives.An addict's concentration on getting drugs often prevents continuing an education or working at a job.His health is often poor.He may be sick one day from
the effects of withdrawal and sick the next day from an overdose.Statistics show that an addict's life span may be shortened by 15 to 20 years.The addict is usually in trouble with the family and almost always in trouble with the law.
Some studies suggest that many of the known narcotic addicts had some trouble with the law before they became addicted.Once addicted,they may become even more involved with crime because it costs so much to support the heroin habit.
Most authorities agree that the addict's involvement with crime is not a direct
effect of the drug itself.Turning to crime is usually the only way to get that much money.The addicts' crimes are nearly always thefts or other crimes againstproperty.
Federal penalties for illegal narcotics usage were established under the Harris
on Act of 1914.The Act provides that illegal possession of narcotics is punishable by fines and/or imprisonment.Sentences can range from 2 to 10 years for the first offense,5 to 20 years for the second,and 10 to 20 years for further offenses.
Illegal sale of narcotics can mean a fine of $20,000 and a sentence from 20 to
40 years for later offenses.A person who sells narcotics to someone under 18 is refused parole and probation,even for the first offense.If the drug is heroin,he
can be sentenced to life imprisonment or to death.
