Cell Phone Lets Your Secret Out
Your cell phone holds secrets about you.Besides the names and _____________(51)that you've pro-
grammed into it,traces of your DNA linger on the device,according to a new study.
DNA is genetic material that______________(52)in every cell.Like your fingerprint,your DNA is unique
to you一 _____________（53)you have an identical twin.Scientists today routinely analyze DNA in blood,
saliva,or hair left _____________(54)at the scene of a crime.The results often help detectives identify
_____________(55)and their victims.Your cell phone can reveal more about you _____________(56)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______________(57).This made her wonder
whether traces of DNA lingered on cell phones even when no blood was involved.______________(58)she and
colleague Margaret Wallace of the City University of New York analyzed the flip-open phones of 10 volun-
teers.They used swabs to collect______________(59)traces of the users from two parts of the phone:the
outside,where the user holds it,and the______________(60),which is placed at the user's ear.
The scientists scrubbed the phones using a solution made mostly______________(61)alcohol.The aim of
washing was to remove all detectable traces of DNA.The owners got their phones______________(62)for
another week.Then the researchers collected the phones and repeated the swabbing of each phone once
more.
The scientists discovered DNA that _____________(63)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 be-
longed to other people who had apparently also handled the phone.______________(64),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
______________(65)of clues
that can clinch a crime-scene investigation._________(60)
A:card
B:keys
C:screen
D:speaker答案：D解析：人们通常在手机中储存人名和他们的电话号码。所以A是最佳选择。虽然手机中也 能储存音乐、电影和秘密信息，相比之下，不如A合理。
这个句子的意思是：DNA是一种存在于每一个细胞中的基因物质。appeal呼吁，吸引， 上诉；appoint任命，指定；appear有，出现；apply申请，应用。只有C项符合语境，故选C。
此句的意思是：如同指纹，你的DNA是独一无二的——除非你有一个与你完全相同的 孪生兄弟或姐妹。因此，此处必须选择unless，其他选择均不符合语境，也违背了有关DNA的基本常识。
leave behind是固定搭配，意为“留下”。
根据对上下文的理解可推知，研究结果是用来帮助侦探识别罪犯和受害人的。由空后 的their victims（他们的受害者）也可知答案。
句子中的more提供了选择的线索，more…than的搭配最能表达该句的意思。
定冠词the说明该选项所指内容在前文中已经提到，即cell phone。除了device（设备， 装置），其他选项均不能指代。ell phone。
前后两个句子是因果关系，故选B。句子大意为：这使她思考微量DNA是否会停留在 手机上，所以，她与同事一起对10名志愿者的翻盖手机进行了分析研究。A、C、D三项表示的 都是转折关系。
句子当中的traces指的是DNA traces，而DNA traces是肉眼看不到的，所以选择invisible。
研究者从手机的两部分收集微量DNA：一是手机外壳，二是喇叭。speaker在此处意为 “喇叭”。
be made of是固定搭配，意为“由……制成”。a solution made mostly of alcohol：一种主要 由酒精制成的溶液。
根据对上下文的理解，应该选择back。本句意思为：手机拥有者拿回了手机，再使用一 个星期。
该句要表达的意思应该是：科学家在每一个手机上发现了属于手机拥有者的DNA。 belong to是固定搭配，意思是“属于”。
空后内容告诉我们手机经过擦洗后仍然有微量DNA出现。所以这里要用surpiisingly 这个副词，表示令人惊讶。
根据对上下文的理解，应该选择list，其他三个选项与句子的意思不符。 -
第5题：
The mobility of cell phones means you can be anywhere and have the____or should I say the convenience, of a phone.A.must
B.accompaniment
C.conclusion
D.necessity答案：D解析：本题考查词语意思。题目意为“手机的移动性意味着你可以在任何地方，并且具有必要性，或者我应该说，手机的方便性。”A项意为“绝对必要的事物”。B项意为“伴奏、伴随物”。C项意为“结论、论断”。D项意为“必需品，必要”。因此选D项，有必要。
