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 DNA left on the device，too，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(唾液)，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 University in 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 her colleague Margaret Wallace of the City University of New York analyzed the flip­open phones of 10 volunteers.They used swabs(药签) 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(擦净)．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 crime­scene investigation.

4

然手机中也能储存音乐和秘密信息，相比之下，不如A项合理。

答案：A

答案：B

4解析：leave behind是固定搭配，“留下”。此处leave使用的是过去分词形式。 答案：D

5解析：根据上下文的理解，研究结果是用来帮助侦探识别罪犯和受害人的，B、C、D三项都不能表达这一层意思。

Ⅳ.1解析：句意：我喜欢这个前面有一个美丽花园的房子，但是我没有足够多的钱去把它买下来。第一句话中的this house表明在该语境中是特指的用法，所以答案为it，表示特指。该题容易误选one，要注意的是one表示泛指。

答案：B

2解析：考查冠词用法。air pollution 是抽象名词，在这里是泛指，weather 在这里特指全球的气候，故前边需用the。

答案：C

4解析：furniture是不可数名词，可排除B项。some不用于否定句，可排除C项。not any 为完全否定，与下文just an old desk(仅有一张旧课桌)矛盾，排除A项。选D项，意为“„„家具不多”，正好与just an old desk呼应。

答案：D

5解析：本题考查动词时态。根据题意，该空表示在过去某段时间(yesterday)内正在进行的动作，意思是昨天我弟弟正在参加比赛，因此，应用过去进行时。
