4．（8分）Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV．
Now one American company is offering its employees a new convenience： a microchip implanted （植入） in their hands． Employees who have these chips can do all kinds of things just by waving their hands． Three Square Market is offering to implant microchips in all of their employees for free． Each chip costs ﹩300 and Three Square Market will pay for the chip． Employees can volunteer to have the chips implanted in their hands． About 50 out of 80 employees have chosen to do so． The president of the company， his wife and their children are also getting chips implanted in their hands．
The chip is about the size of a grain of rice． Implanting the chip only takes about a second and is said to hurt only very briefly． The chips go under the skin between the thumb and forefinger． With a chip in the hand， a person can enter the office building， buy food， sign into computers and more， simply by waving that hand near a scanner． The chips will be also used to identify employees． Employees who want convenience， but do not want to have a microchip implanted under their skin， can wear a wristband （腕带） or a ring with a chip instead． They can perform the same tasks with a wave of their hands as if they had an implanted chip．
Three Square Market is the first company in the United States to offer to implant chips in its employees． Epicenter， a company in Sweden， has been implanting chips in its employees for a while．
Three Square Market says the chip cannot track the employees． The company says scanners can read the chips only when they are within a few inches of them． "The chips protect against identity theft， similar， to credit cards．" The U．S． Food and Drug Administration approved the chips back in 2004，so they should be safe for humans， according to the company．
In the future， people with the chips may be able to do more with them， even outside the office． Todd Westby is Chief Executive Officer of Three Square Market． He says， "Eventually， this technology will become standardized allowing you to use this as your passport， public transit， all purchasing opportunities， etc．"

【分析】这是一篇说明文．文章主要讲了技术带给人们方便，一家美国公司通过给员工手里植入芯片来带给员工方便．
【解答】1．B．推理判断题．答案定位在第三段The chip is about the size of a grain of rice． Implanting the chip only takes about a second and is said to hurt only very briefly．可知第三段讲述的是芯片的优点，故选B．
2．C．词义猜测题．答案定位在倒数第二段The company says scanners can read the chips only when they are within a few inches of them．公司说扫描仪只能在几英寸以内才能读取芯片．由此可知them指代的就是scanners，故选C．
