8.Social media is one of the fastest-growing industries in today's world.A study conducted (实施) by the US think tank (智囊团) Pew Research Center showed that 92percent of teenagers go online daily.
The wide spread of social media has changed nearly all parts of teenagers'lives.
Changing relationships
High school student Elly Cooper from Illinois said social media often reduces face-to-face communication.
"It makes in-person relationships harder because people give attention to their phones instead of their boyfriends or girlfriends,"Cooper said.
There's also a greater possibility of things getting lost in translation over social media.
"If half of your relationship is over social media,you don't really know how the other person is reacting,"Sienna Schulte,a junior student from Illinois,said.
Yet,some people believe social media has made it easier to start relationships with anyone from anywhere.Beth Kaplan from Illinois met her long-distance friend through social media.He currently lives in Scotland,but they're still able to frequently communicate with one another.
"I can feel close to someone that I'm talking to via (通过) FaceTime,"Kaplan said.
Wanting to be"liked"
The rise of social media has changed the way teenagers see themselves.
The 19-year-old Essena O'Neill announced on the social networking service Instagram that she was quitting social media because it made her obsessed (痴迷) with appearing perfect online.
Negative comments also can do great damage to a teenager's self-esteem (自尊).
In particular,anonymous (匿名的) social media apps such as Yik Yak may provide opportunities for cyber bullying (网络欺凌).
The app allows users within 5miles (8km) to create and add comments to everything.Teenagers who get negative comments on these sites can't help but feel hurt.
Opening new doors
However,Armin Korsos,a student from Illinois,takes advantage of the comments he receives over social media to improve his videos on the social networking site Youtube.
"Social media can help people show themselves and their talents to the world in a way that was never possible before,"Korsos said.
But Korsos recognizes that social media has become a distraction (让人分心的事).
"Social media,though it helps people connect with their friends and stay updated (信息更新的),is not all necessary."

67.What is the article mainly about?B
A.The major problems with social media.
B.The impact of social media on teenagers.
C.How teenagers benefit from social media.
D.Why social media appeals so much to teenagers.
68.How does social media change relationships,according to the article?D
A.It pushes people to meet their friends more often offline.
B.It encourages people to pay more attention to those around them.
C.It enables users to understand accurately what others are talking about online.
D.It allows people to keep in touch with their friends who live far away more easily.
69.Essena O'Neill decided to disconnect herself from social media becauseC.
A.she couldn't put up with cyberbullying on social media
B.she wanted to spend more time with her friends in reality
C.she was bothered by her desire to look perfect on social media
D.she wanted to reduce her exposure to negative information online
70.Which statement about the use of social media would Armin Korsos probably agree with?D
A.The use of social media taught him to turn negative comments into motivations.
B.Social media can easily become an addiction,despite its benefits.
C.Social media is mostly a distraction to teenagers,so it is unnecessary for it to exist.
D.If used well,social media can create opportunities for teenagers to develop themselves.

19.How often do you let other people's nonsense change your mood?Do you let a bad driver,impolite waiter,rude boss,or an insensitive employee(36)Byour day?
Sixteen years ago I learned this lesson in the back of a New York City taxi cab.One day I was in a taxi and we headed(37)Dthe airport.We were driving in the(38)Blane when suddenly a black car drove out of a parking space right in front of us.My taxi driver slammed on his(39)A.slide sideways.and at the very last moment our car stopped and(40)Cthe other car by just inches!The driver of the ther car,the guy  who almost caused a big accident,looked around and started(41)Dat us.
My taxi driver just(42)Band waved at the guy.And I mean,he was(43)Aso I said,"Why did you just do that?This guy almost ruined your car and sent us to the hospital!"This is when my taxi driver aught me what I now call"The Law of the Garbage Truck".
He said,"Many people are like garbage trucks.They run around full of(44)C,fall of frustration,full of anger,and fall of disappointment.As their garbage (45)Dup,they need a place to dump it and sometimes they'll dump it on(46)C.Don't take it personally; Just smile,wave,wish them well,and move on.Believe me.You'll be(47)B."
So I started thinking,how often do I let Garbage Trucks run right over me?And how often do I take their garbage and(48)Ait to other people at work,at home,or on the street?It was then that I said,"I don't want their garbage and I'm not going to spread it anymore."

16.Dear Sir,
I have to travel every day from Souk Road to the airport.Two buses travel along their route:the number 49and number 16.But by the time the number 16bus reaches Souk Road it is always full,so I can't get on it.I have to wait for the number 49,because sometimes there are empty seats on it.
The timetable says that there are buses from Souk Road to the airport every ten minutes.If this is so,why do I have to wait half an hour for a bus nearly every day?
The regulations (规章) say that if there are empty seats on a bus,the bus must stop at every stop where people are waiting.Why do the half-empty buses go straight past me when I am standing at the bus stop?
The regulations say that no bus may carry more than 40seated passengers and 20standing passengers.Yesterday I was the first to get off the bus when it reached the airport.I counted the other passengers as they got off.There were 129of them.
It is clear that our bus companies break the regulations and think little of their passengers.Can nothing be done to make your service better?
Yours,
Tired passenger

21.The writer has to take Bus No.49becauseB.
A.it arrives on time               B.it is not always full
C.it travels faster                D.it has fewer seats on it
22.The regulations say that each bus may carryC passengers at most.
A.20           B.40          
C.60           D.129
23.From the passage we can infer that the writer of the letter is probablyA.
A.an airport worker                 B.a bus driver
C.a very tired traveler             D.an English teacher
24.What kind of letter is this passage?D
A.It's a letter of thanks            B.It's a letter of apology
C.It's a letter of introduction      D.It's a letter of complaint(投诉)

13.The Chinese television reality show called"Wonderful Friends",where entertainers hug whale sharks,kiss lions,feed pandas and dress up baby chimpanzees,has come under fire from wildlife protectors who want it to be stopped,saying such activities are cruel and are dangerous for both the humans and animals.
The show is the latest hit from Hunan TV,which has attracted more than 196,000followers.In each show,popular stars are given zoo-keeping tasks that allow them to interact with wild animals in order to bring humans and animals closer together.
Animal welfare advocates say that is exactly what should be avoided.Dave Neale of Animals Asia (an advocacy group) said,"It is hugely misleading to the public about the needs and welfare of captive animals (圈养动物) and putting the animals'welfare and health at risk."
"What they don't realize is that wild animals need space,"said Xie Yan,a zoologist and China director of the Wildlife Conservation Society."Putting clothes on chimpanzees is not as adorable as you may think from the animals'point of view.I guess their idea was to get their viewers to love and protect the animals,"Ms.Xie added,"but we do not agree with this approach for entertainment."
Using famous people to focus public attention on wildlife is a common practice in conservation campaigns.The Chinese basketball legend Yao Ming went to Africa and highlighted the problem of elephant and rhinoceros poaching (偷猎) in the documentary"The End of the Wild"."But differently,he,as a human observer,kept his distance and was there to see the hard truth of poaching,and that is different from a show created to attract viewers."Ms Xie said.
Critics also argue that the show violates (违反) Chinese wildlife protection laws.

24.Which one of the following statements is TRUE?D
A.Many people like the show because of its dangerous activities.
B.Xie Yan is against persuading the public to love and protect animals.
C.The reality show makes no difference to wildlife at all.
D.Some think the show is against wildlife protection laws of China.
25.According to Ms Xie,"Wonderful Friends"is basically different from"The End of the Wild",becauseD.
A.they both invite different popular stars to show up
B.they shoot different numbers and kinds of species
C.their filming locations are different
D.their purposes and ways to approach animals are different
26.What's the author's attitude towards"Wonderful Friends"?D
A.Worried.         B.Disappointed.
C.Uninterested.    D.Not mentioned.
27.The passage would most likely be foundB.
A.on a notice board  
B.in a newspaper
C.in a fashion magazine  
D.in an ad of wildlife protection.

20.When it comes to public speaking,the most important thing is to speak clearly.You want the audience(61)to hear (hear) everything you have to say when giving public speeches,not to question your words later (62)becausethey couldn't hear you.A good public speaker is the person who knows (63)howto speak clearly.
Practice (64)makes(make) perfect.Try practicing in front of a mirror,in front of your friends,or even in front of your pet dogs if you need help.
Use the proper tone when speaking.Most people find (65)iteasy to slip into a monotone voice,where every word that comes out of their mouth sounds the same.Not only (66)does(do) this bore the audience,but it also makes you hard to understand and follow.
Pronounce your words carefully and clearly.This means (67)using (use) the right pronunciation of words.If you have any questions on how a word is pronounced,ask for help beforehand.
Speak slowly so that the audience can hear you.If your natural speed is fast,practice speaking at a (68)slower(slow) pace than usual before your speech.
Project your voice when (69)needed (need).You don't need to scream at the audience,but your voice rise (70)slightly(slight) if people in the back of the room can't hear your speech.

17.Want to Live Longer?Turn off Your TV!
Seating yourself in front of the TV probably is relaxing,but spending too much time in front of the  tube may take years off your life.
That's what Australian researchers found when they collected TV viewing information from more than 11,000people older than 25years.The study found that people who watched an average six hours of TV a day lived an average 4.8years less than those who didn't watch any television.Also,every hour of TV that participants watched after age 25was associated with a 22minute reduction in their life expectancy.
It's no mystery that sitting in front of the tube isn't exactly a healthy pursuit.The more TV you watch,the less physically active you are.And the less exercise you get,the more likely you are to develop diseases such as diabetes or heart problems.
Lennert Veerman at the University of Queensland is the lead author of the study.He acknowledges that it may not just be the longtime sitting nature of watching TV that lowers life expectancy,but also the poor diet that onscreen junk-food advertising can promote.But Veerman says that the association between watching too much TV and lower life expectancy persists,even after adjusting for diet.
Veerman says that it might make sense for doctors to start asking their patients about how much time they spend in front of the TV.This may be a better way to treat patients than just asking them to get more exercise or have a healthy diet.
Veerman points out that people who are concerned can simply turn off the TV and get off the couch."Exercise is good,"he says,"but even light physical activity also improves health."
58.The underlined word"tube"in the 1st paragraph refers to theB.
A.pipe  
B.television
C.couch  
D.table
59.Watching too much TV may shorten our life becauseA.
A.the lack of physical activity can lead to developing diseases
B.while watching TV we usually have a poor diet
C.too much TV leads to less sleep
D.watching TV makes us tired
60.According to Lennert Veerman,D.
A.the more TV we watch,the shorter life we'll live
B.the more exercise we take,the healthier we'll be
C.say No to TV absolutely
D.watching less TV and taking some exercise may help us live a longer life.
