2009年职称英语教材完型填空新增部分(理工类)

　　10.D 打个盹有两个好处：1)可以减少错误和事故;2)可以增加工作效率。从上下文判断，

　　选als0最合适。t00从词义上说也可以，但用法上有问题，因为“…this…too increases the amount…”把t00置于动词increases之前很少见。never和seldom的意思与上下文不匹配。

　　11.C前半句说，“people should not carry out important dudes…”，后半句自然会想到“when they feel sleepy”。而when they feel ready good happy都说不通。

　　12.A本句的意思是：大约20分钟的打盹是你所需要的。所以，About twenty minutes of rest is few/any/nothing you need与上述意思不符，只有About twenty minutes of rest is all you need才说得通。

　　13.C前半句说，“this(指打肫)provides extra energy and Can increase your effectiveness”后面接while unless during the end of the day不搭配，只有until(the end of the day)才是答案。

　　14.D本句的意思是：专家警告说：打盹不能(或不应该)超过30分钟。这题选should最合适。

　　15.B本句表达的意思应该是上一句“A longer nap will put the body into deep sleep”引出的结果。打盹时间长了，就会进入深睡状态，很难醒过来。选difficult是合适的，其它三个选项的意思脱离了上下文，不会是答案。

　　Cell Phone Lets Your Secret Out

　　Your cell phone holds secrets about you. Besides the names and　　1　　that you've programmed into it, traces of your DNA2linger on the device, according to a new study.

　　DNA is genetic material that　　2　　in every cell. Like your fingerprint, your DNA is unique to you　　3　　you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left 4 at the scene of a crime. The results often help detectives identify 5 and their victims. Your cell phone can reveal more about you　　6　　you might think.

　　Meghan J. McFadden, a scientist at McMaster University1in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the　　7　 This made her wonder whether traces of DNA lingered on cell phones--even when no blood was involved.　　 8　　she and colleague Margaret Wallace of the City University of New York analyzed the flip-open phones3 of 10 volunteers. They used swabs to collect　　9　　traces of the users from two parts of the phone: the outside, where the user holds it, and the　　10　　, which is placed at the user's ear.

　　The scientists scrubbed the phones using a solution made mostly　　11　　alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones　　12　　for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.

　　The scientists discovered DNA that　　13　　to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, but those swabs also picked up DNA that belonged to other people who had apparently also handled the phone.　 14　　, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the　　15　　of clues that can clinch a crime-scene investigation.
