AWith smartphones rapidly becoming the most common mobile device (设备) throughout countries, an increasing number of teenagers have access to the Internet using their phones. And if they have access to the Internet they have access to Apps (an App is a small program designed to run on mobile devices). Most Apps popular with teenagers are either for play, connecting with friends, or both at the same time. Here are some of the most popular Apps teens are downloading at the moment.Draw SomethingIt's a very popular App at the moment. It's an online version (版本) of Pictionary, where you invite friends on Facebook to compete. Each round you are given 3 words to choose from of which you must draw. Your competitor must guess correctly so that both of you can receive coins to buy additional colour tools. Fun for any age. InstagramThis App is about sharing photos. Similar to Twitter, you follow people and they follow you. New photos show up in a “news feed” where you can comment on photos. You can also view popular photos and have the choice of making your photos public (everyone can see them) and anyone can “follow” you. It's a good idea to consider privacy settings as once photos are uploaded (上传) anyone can have access to them. ViddySimilar to Instagram, except it's all about videos. Film a video and immediately upload it. Again people can follow you and you can follow people. You can see“what's hot” — the most popular and newest videos. In addition you can share videos you have.OldifyThis is fun and easy to use. Upload a photo of yourself or a friend by either taking a photo or using one from your photo library, line up the eyes and lips, press a button and the photo of you or the person you uploaded will appear as a person 50 years older! By touching the screen the face will react.21．Draw Something is an App that ________.A．children like mostB．is for users of any ageC．users can use to share picturesD．is used to buy paintings online22．When using Instagram, users should ________.A．make their photos publicB．comment on their friends' photosC．pay special attention to their privacyD．follow people to view popular photos23．What do we know about Oldify?_______A．It helps users to beautify their photos.B．It allows users to share their opinions.C．It is a frightening but fun online game.D．It enables users to see their aged appearances.BYou can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely associated to the big problem of global-warming.24．What is the best title for the passage?A. Strategies to Save MoneyB. Ways to be Earth-FriendlyC. Strategies to End Global-WarmingD. Ways to Limit Carbon Dioxide25．According to the writer, what will happen if our PC is switched off when not in use?A. It will help to save a large amount of money.B. It will help to reduce a great deal of CO2.C. It will save the amount of oil that runs your car for a mile.D. It will be like planting 1.7 million acres of new trees.26．Which strategies suggest recycling or reuse of things?A. Strategies 1 & 3.B. Strategies 2 & 5.C. Strategies 3 & 6.D. Strategies 4 & 5.27．What benefits do these strategies have in common?A. They all help reduce the use of energy like electricity.B. They all cut down the amount of the use of paper.C. They all result in producing less greenhouse gases.D. They all aid to preserve our trees and forest.CInsects trapped in fossilized amber (琥珀) for tens of millions of years have provided the key to creating a new generation of antibiotic drugs that could start a war against modern diseases. Scientists have isolated the antibiotics from microbes(微生物) found either from these insects or in soil particles trapped with them when they were caught by sticky tree risen up to 130 million years ago.Present-day antibiotics have nearly all been isolated from microbes that use them as a form of defense against their enemies and competitors. But since the introduction of antibiotics into medicine 50 years ago, an alarming number have become ineffective because many bacteria have developed resistance to the drugs. Research over the past two years has uncovered at least four antibiotics from the microbes and one has been able to kill modern drug-resistant bacteria that can cause potentially deadly diseases in humans.Raul Cano, who has pioneered the research at the California Polytechnic State University, said the ancient antibiotics had been successful in fighting drug-resistant strains of staphylococcus (葡萄球菌)，a “superbug” that had threatened the health of patients in hospitals across the globe. He now intends to establish whether theantibiotics might have side effects. “The problem is how toxic they are to other cells and h ow easy they are to purify”，said Cano.Cano's findings have been acknowledged as a breakthrough. A biotechnology company, Ambergene, has been set up to develop the antibiotics into drugs. If any ancient microbes are revived (复活) that resemble present-day disease, they will be destroyed in case they escape and cause new epidemics. Drug companies will be anxious to study the chemical structures of the prehistoric antibiotics to see how they differ from modern drugs. They hope that one ancient molecule could be used as a basis to produce a range of drugs.However, even the use of ancient antibiotics may not stop the rise of drug-resistant bacteria. Stuart Levy warned that the bacteria would eventually evolve to fight back against the new drugs. “There might a lso be an enzyme already out there that can degrade it. So the only way to keep the life of that antibiotic going is to use it sensibly and not excessively，” he said.28. What problem has man faced since the use of antibiotics as medicine according to the passage?A. Antibiotics are very difficult to purify.B. Antibiotics do harm to human health.C. Antibiotics resemble some disease-causing bacteria.D. Antibiotics are becoming ineffective in fighting against bacteria.29. Why are Cano's findings considered as a breakthrough in science?A. His discoveries will help revive ancient microbes.B. His discoveries will put an end to the rise of drug-resistant bacteria.C. The company Ambergene has applied the prehistoric antibiotics to drugs.D. The prehistoric antibiotics proved more deadly against drug-resistant modern bacteria.30.According to the last paragraph, what is Stuart Levy's attitude towards the use of ancient antibiotics ?A. Cautious.B. Contradictory.C. Confident.D. Critical.31. Which of the following can be the best title for the passage?A. Antibiotics－Dangerous or Not?B. Biotechnology Revealed Prehistoric SecretsC. Insect Antibiotics and Bacteria EvolutionD. Prehistoric Insects Might Help Invent New DrugsDNext week California will try to take cell phones from the hands of drivers, telling everyone from millionaires to workers that conversations behind the wheel must be on an earphone.Californians interviewed by Reuters mostly supported the law requiring hands-free phones in cars and banning cell phones entirely for drivers under 18, which will take effect on Tuesday, though they were puzzled by a loophole(漏洞) that allows seemingly more dangerous text messaging. Some were doubtful about lawmakers, who they blamed for failing to build more freeways or public transportation in the face of increasingly crowded roads in the nation’s most populous state and said hands-free conversations were not safer.KFI-AM radio talk-show host John Kobylt told Reuters. “It's s tupid because we’ve one over about seven different studies and each one of them says it’s the conversation that distracts you, not holding the phone.”State Senator Joe Simitian, who introduced the bill, said keeping both hands on the wheel was always safer. He expected his law to save hundreds of lives. The Democratic lawmaker was considering introducing a new law to ban text messaging inthe car, which he said wasn’t an issue when he began working on the first one in 2001.Connecticut, New Jersey and New York have already banned drivers from talking on hand-held cell phones. In New Jersey, police have issued 35,000 tickets for using a hand-held phone or texting while driving since the law went into effect on March 1.But Californians interviewed by Reuters expressed ambivalence.“On the one hand I don’t want to see people crash into each other, but I'm not going to get an ear thing.” 38-year-old bank employee Jason Fischer said in Los Angeles.32. We can infer from Paragraph 2 that______.A. most Californians hate to use an earphone while making a call in the carB. public transportation in California isn’t developed enoughC. in New Jersey few people use a hand-held phoneD．most of Californians are probably against the new law33. According to John Kobylt，_________.A. all the lawmakers are stupidB. holding the phone is safer than using an earphoneC. it isn’t dangerous to make a phone call while drivingD. it is the phone conversation while driving that is really dangerous34. What will State Senator Joe Simitian probably do in the future？A. He will suggest a law to forbid text messaging while rivingB. He will conduct a new survey among CaliforniansC. He will suggest building more roads in CaliforniaD. He will suggest a law to completely ban cell phones while driving.35. The underlined word “ambivalence” in the last paragraph probably refers to__.A. a positive attitudeB. a negative attitudeC. a confused feelingD. an excited feeling第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。
