2、Lakes, Too, Feel Global WarmingThere\'s no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming ａｎｄ　trying to figure out what to do about it.Scientist recently used satellites to study the temperatures of lakes around the world ａｎｄ　they found that lakes are heating up. Between 1985 ａｎｄ　2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) ａｎｄ　algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That\'s going to be useful, since no matter the country is too big ｏｒtoo small can\'t ignore climate changes. Scientists aren\'t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.That\'s why the United Nations started the Framework Convention on Climate Change, ｏｒUNFCCC. Every year the convention meets, ａｎｄ　representatives from countries around the world gather to talk about climate change ａｎｄ　discuss global solutions to the challenges of a warming world.Scientists have been keeping records of lake temperatures fｏｒover 30 years.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题难度不大，答案依据比较明显，在文章第二段第二句：Between 1985 ａｎｄ　2009，satellites recorded the nighttime temperatures of the surfaces of 1671 akes.很明显，是24年，而不是30多年，题干和原文句意不符，答案是B。

3、The policemen acted quickly because lives were at stake.【单选题】

A.in danger

B.in difficulty

C.in despair

D.out of control

正确答案:A

答案解析:因生命危在旦夕，警察迅速行动。本题有一定难度，虽然选项都是常用的固定介词词组，但干扰项干扰较大。Atstake和in danger都有“在危险中”的意思，是近义词。B项指“在困难中”，C项指“处于绝望中”，D项指“失去控制”，最佳答案是A。

4、The Book of LifeSo far, scientists have named about 1.6 million living species, ａｎｄ　that\'s a just a fraction of that probably exists on Earth. With so many plants, animals ａｎｄ　other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg ｏｒwhat kind of bird is flying by.A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.To get the encyclopedia started, the creators will use information from scientific ｄａｔａｂａｓｅs that already exist. ａｎｄ　eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, fｏｒexample, will be able to input which bird they\'ve seen ａｎｄ　where. The technology fｏｒthis kind of tool has only become available.As the EOL develops, you might find it useful fｏｒschool projects. The site will feature special pages fｏｒkids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven\'t been reviewed.Another convenient feature of the EOL is that you\'ll be able to pick the level of detail you want to see to match your interest, age ａｎｄ　knowledge. If you wanted to learn about bears fｏｒa science class report, fｏｒexample, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature ａｎｄ　exploration of bears.It now takes years fｏｒscientist to collect all the data they need to describe ａｎｄ　analyze species. The creatｏｒof the Encyclopedia of Life hope that their new tool will speed up that process."Spider" ａｎｄ　"bird" mentioned in Paragraph 1 are examples to illustrate ______.【单选题】

A.there are numerous living species on Earth

B.animals are people\'s friends

C.it is easy to see spiders ａｎｄ　birds

D.here are many types of spiders ａｎｄ　birds

正确答案:A

答案解析:本题有一定难度，带着题干信息词回文章定位，答案依据主要在文章第一段：So far, scientists have named about l.6 million living species, ...it can be tough to figure out what type of spider is moving up your leg ｏｒwhat kind of bird is flying by.谈到了地球物种数量巨大，回来看选项，A项和原文句意相近，是答案。

5、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names ａｎｄ　______ that you\'ve programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you- because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, ｏｒhair left behind at the scene of a crime. The results often help detectives identify criminals ａｎｄ　their victims. Your cell phone can reveal more about you than 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 device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she ａｎｄ　colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect invisible traces of the users from two parts of the phone: the outside, where the user holds it, ａｎｄ　the speaker, which is placed at the user\'s ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back fｏｒanother week. Then the researchers collected the phones ａｎｄ　repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone\'s speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, 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 list of clues that can clinch a crime scene investigation.【单选题】

A.numbers

B.music

C.secrets

D.films

正确答案:A

答案解析:人们通常在手机中储存人名和他们的电话号码。所以电话号码是最佳选择。虽然手机中也能储存音乐、秘密信息或者电影，相比之下，不如电话号码合理。
