I Believe it or not,cell phones have been around for over a quarter of a century.The first commercial
cell phone systemfl was developed by the Japancoc in I 979.But cell phones have changed a lot
since that
time.The early cell phones were big and heavy but they have developed into small and light palm-sized mod-
els.There have been huge (lcveloprnents in their functions,too;we have had call forwarding,text messaging,
answering services and hands-free use for years,but now there are countless new facilities,su,ch as instant ac-
cess to the Internet and receiving and sending photos.
2 Cell phones have become very common in our lives;recent statistics suggest as many as one in three
people cii the planet now have a cell phone,and most of them say they couldn't live without one.Cell phones
are used in every area of our lives and have become a necessary tool,used for essential arrangements,social
contact and business.They have made it easier to call for help on the highway.They have made it possible to
keep in touch with people"on the move”一when people are traveling.
3 Cell phones have made communication easier and have reduced the need for family arguments.We
can use cell phones to let our family know we'11 be late or if there’。a sudden change of tian or an emergen-
cy.Cell phones have eased the worries of millions of parents when their teenagers are out late,they can now
contact their children at any time.
4 This does not mean that cell phones are all good news.They have brought with them a number of
new headaches for their owners;it costs a lot to replace stolen phones,something that is becoming a frequent
occurrence,and have you ever seen such huge phone bills? More serious,however,is the potential health
problem they bring:there are fears that radiation from the phones may cause brain tumor（肿瘤）.This may be
a time bomb waiting to happen to younger people who have grown up with cell phones that they simply can't
live without!Cell phones are common in our lives and have become_________.

第7题：
单选题According to the passage, which of the following statements is NOT true?AThe potential health hazards of mobile phones call for further research.
BThe Australian scientists find no connection between growth of tumors in human body and radiation from mobile phones.
CThe Italian scientists’ belief is shared by other scientists.
DThe British government inquiry didn’t establish any link between health risks and use of mobile phones.
正确答案： A解析：
事实细节的识别和判断。根据原文可知，澳大利亚科学家发现手机辐射并不能引发肿瘤的增长(...have shown that radiation from mobile phones does not trigger the growth of tumors)，由此可见选项B的说法与原文不符，是正确答案。
【录音原文】
Italian scientists have raised new health concerns about the safety of using mobile phones, with research showing radio waves from the handsets makes cancerous cells grow more aggressively. When Fiorenzo Marinelli and his colleagues at the National Research Council in Bologna exposed leukemia cells in the laboratory to 48 hours of continuous radio waves they initially killed the cancer cells but then made the surviving tumor cells replicate more rapidly.
“We don’t know what the effects would be on healthy human cells,” Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively.
The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors.
The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively. -

单选题According to the passage, which of the following statements about the cell phone service at Yellowstone is TRUE?AIt is limited to certain areas in the park.
BIt is available everywhere in the park.
CIt is not available in the park.
DIt is available to visitors at a fee.
正确答案： B解析：
由原文第二段中的“...cell phone service at Yellowstone is available in parts of the park with stores and campgrounds”可知，公园里只能在商店和宿营地才可以使用手机。即在公园里有限的特定区域才可以使用手机，因此A项正确。 -
第11题：
单选题According to the passage, Asian civilizations, which were ahead of Europe’s, fell behind because ______.AAsian languages were more difficult to learn
BEuropean languages had simple alphabets
Cthey didn’t have the technology to spread ideas
Dpeople’s communication skills were not good enough
正确答案： B解析：
第三段第二句指出“One reason why Asia’s civilizations, in 1000 far ahead of Europe’s, then fell behind was that they lacked the technology to reproduce and diffuse ideas”，由此可知曾经领先于欧洲的亚洲文明落后的原因是他们缺乏传播思想的技术，因此选项C符合文意。reproduce复制；再生。diffuse扩散；传播。 -
第12题：
单选题According to the passage, which of the following did NOT happen in the room where the college entrance exam was going on?AThe teachers in the exam hall tried to stop the police from entering into the room.
BSome examinees sent answers with mobile phones to people outside the room to make profits.
CThe mobile phones were confiscated by the police.
DSome examinees forwarded answers to people who have paid a lot of money.
正确答案： A解析：
语义的理解和判断。该段录音与一次考试作弊案相关，开头便指出警察试图进入学生参加大学入学考试的大厅，但是“They were blocked by teachers but later confiscated mobile phones…”，由此可知，虽然教师们不让警察进入考试大厅，但后来警察们还是没收了被用于考试作弊的手机，因此选项A、C均与录音原文相符。接着录音中指出考场里最聪明的学生将答案做出后，发给younger students outside the hall（考场外年纪小一点的学生）手中，然后这些学生再将答案转发给已付过钱的人，由此可见，B项内容也与录音原文相符。但D项所描述的（一些考生将答案转发给已付过钱的人）与录音中提到的“发给考场外年纪小一点的学生”不符。
【录音原文】
Acting on a tip off—the police tried to raid a hall where students were taking the college entrance exam last month. They were blocked by teachers but later confiscated mobile phones that had been smuggled into the room—and uncovered what they said was an elaborate cheating system. The brightest students known as “players” finished their multiple choice papers quickly then sent off the answers by text message to younger students outside the hall. They forwarded the information to others who paid up to 1, 000 dollars to take part. -

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

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18题：
单选题According to the passage, which of the following statements about the Tuskegee Airmen is TRUE?AIn World WarⅡ, they never lost a bomber to enemy fire.
BThey were the first group of black soldiers ever trained by the ground troops.
CThey were not subjected to racial discrimination in the army.
DThey were already soldiers in the ground troops before their training at Tuskegee began.
正确答案： D解析：
细节理解题。根据文章的第三段第二句“They did not lose any of the bombers they were escorting”可知，在战争中，他们从来没有失去他们护航的任何一架轰炸机。而A项说的是他们没有遗失一架轰炸机给敌人火力。与A项说法一致，所以A是正确选项。根据文中第二段“The first African-American airmen reported for duty in l941.”可知，他们是第一批报到的空军，而B项的描述是他们是第一批受陆军训练的黑人士兵，原文并没有提到这一点，所以B项错误。根据文中第一段“separated you from other soldiers because of the color of your skin”以及后面的第三，四段可知，他们即使在军队里也被歧视，也受到了种族歧视的影响，C项描述完全相反。由文中第二段第二句“Before that, African Americans could only serve in the Armed Forces as part of the ground troops.”可知，第一批被训练的空军之前是作为地面部队的一部分为武装部队服役，服役指的是参加部队的劳动或是参军，所以不代表他们都是地面部队的士兵。故D项错误。 -

BThe museums were out-of-date.
CThe areas were not safe.
DThe patrons were not well educated.
正确答案： C解析：
细节题。文章最后一段最后一句提到“because patrons became reluctant to enter high-crime areas in which these centers were located”，即“游览者不愿意进入犯罪率高的地区”，C项“这些地区不安全”表述与其一致。 -

BShould National Parks Allow the Use of Cell Phones?
CWhat Did Yellowstone Do to Enrich Park Visitors’ Experience?
DCan Technology Transform the Way People Experience Nature?
正确答案： B解析：
主旨大意题。原文第一段中就引出了文章的话题“Should park visitors be able to use cell phones，or should their use be restricted?（国家公园该不该限制游客使用手机?）”，接着针对这一问题阐述了正方和反方的观点。因此本文最佳标题应为B项。 -
第21题：

Bjobs were more dangerous then
Cthey had bigger families to look after
Dmoney was given away with the policies
正确答案： A解析：
文中提到20世纪20、30年代是一个充斥着mass unemployment-economic insecurity和a passionate concern for the next generation的年代，由此可知读者之所以会对报纸和杂志提供的免费保险所吸引是因为他们担心失去工作后没有依靠，故A项正确。 -
第22题：
单选题According to the passage, which of the following statements is TRUE?AAfter the cell-phone ban is ended, students can use their phones during class.
BThe cell-phone ban is equally enforced in all public schools.
CThe cell-phone ban was put into place in 2008 under mayor Bill de Blasio.
DA phone-storage industry has appeared outside the 88 metal-detector campuses.
正确答案： B解析：
根据第四段第二句“Ending the ban will also likely end an industry that has sprung up near…other devices for a dollar a day”可知，众多学校周边曾经兴起一桩生意：为青少年保存手机和其他设备，费用为一天一美元。又根据文中第三段第一句“But at the 88 city schools with metal detectors”可知是88所具有金属探测器的学校，因此可判断正确答案为D。根据文章最后一句话“It will include rules about not using the phones during class or to cheat on tests”可知，上课或考试时使用手机是不允许的，A项错误。根据文章首句“which is not equally enforced in all schools”可以判断，B项错误。根据文章第四段首句“The ban was put into place in 2007 under mayor Michael Bloomberg”可知，该禁令是2007年Michael Bloomberg实施的，因此可以判断C项错误。 -
第23题：
单选题Which of the following is the main idea of the passage?ANew York City will give financial aid to poor students.
BNew York City plans to restrict cell phone use in libraries.
CNew York City plans to install metal detectors in all public schools.
DNew York City will soon end a ban on cell phones in schools.
正确答案： C解析：
主旨大意题。文章第一部分即第一段，点明主旨，提出将结束引起争议的手机禁令。第二部分包括第二、三、四、五段，指出这项禁令的实施所带来的利与弊。第三部分即第六段，指出教育部因此决定创建一个新的政策。由此可知正确答案为D（纽约很快会结束学校的手机禁令）。A、B项与主题不符，C项只是文章中的一个细节，只有D项才是文章的主要内容。 -
第24题：
单选题According to the passage, gramophones were sometimes ineffective because they ______.Agot out of synchronization with pictures
Bwere too large for most movie theaters
Cwere newly invented
Dchanged speeds when the needle jumped
正确答案： A解析：
第一段最后一句介绍了把留声机作为音响系统所存在的弊端，指出如果gramophone needle（唱针）jumped，或投影仪的速度发生了变化，那么声音和图像就会变得unsynchronized（不同步的），因此A项符合题意。
