5.Something has to be done to stop the rivers from being further polluted,_____?(  )
A.doesn't itB.hasn't itC.does itD.has it

分析 必須采取措施來(lái)阻止河流進(jìn)一步的被污染,是嗎?

解答 答案:A   Have/has/had to表示"不得不,必須"時(shí),反意疑問(wèn)句用don't/doesn't/didn't.不定代詞Something作主語(yǔ),反意疑問(wèn)句用it.故選A

點(diǎn)評(píng) 考生要注意分析句中謂語(yǔ)動(dòng)詞的含義,有些動(dòng)詞既可以作為助動(dòng)詞,又可以作為實(shí)意動(dòng)詞.

1.The malls were filled with people seeking gifts for their loved ones.Some of the malls remained open around the clock,partly to satisfy our needs to buy gifts.
Behind the materialistic aspect of shopping for gifts lies the idea of caring,being attentive to the desires of special people in our lives.However,to use a well-worn play on words:it is our presence,not our presents,that truly counts.Many of us,unfortunately,can be so inattentive,even in the presence of our loved ones,that we might as well not be there at all.
Attention is one of the greatest gifts we can give each other.Companies around the globe spend billions every year on advertising to catch our attention for just a short moment at a time.Whole industries-media,entertainment,education-rely on the precious gift of our attention for their continued existence.A baby lacking attention for a long time is likely to be psychologically unhealthy.
In earlier times,both diet and attention could be left unregulated (沒(méi)人管的) without major cause for concern.There were natural checks and balances:limited availability of food meant few got fat,for example.Similarly,in bygone times we might have spent a few hours communicating with the village storyteller; today,watching an entire TV series,while speaking to nobody,is common.In traditional societies,with smaller population,everyone would get a fair deal of attention.On many issues we might go to see Grandma or Grandpa; now we have Google and Wikipedia.
"She just wants attention."people tend to think little of those doing things simply for attention.But the truth is that human beings need attention,and giving attention to each other is,to a large extent,what human civilization is based upon.This perhaps explains the runaway success of social networking sites such as Twitter and Facebook.While we use such sites for"micro Hogging","idea voicing"and"status updates"-the reality is that we are often doing no more or less than fulfilling our basic human drive for attention exchange.
I friend you,you friend me,I retweet you,you retweet me.The charming ease with which we can now get and give attention is why many people appear overly attached to their smart phones.It is also a vicious (惡性的) circle.As ever more people are busy exchanging attention online,there is increasingly lessattention to be paid in the real world,which forces more people to seek their attention exchange online,or else risk attention-starvation.
The very nature of attention exchange is being rapidly transformed,and there is a danger that some of us will develop unhealthy practices.Just as eating red meat every day is a bad idea,so it is with too much attention exchange.The biological consequences of our technological advancement in food production are highly visible; heart disease,diabetes and obesity.The consequences of our transformed attention exchanges will be psychological and social,and so may take longer to identify,but they will be equally damaging.
Face-to-face attention is becoming rarer,and therefore more valuable.In a sense it is priceless.And it is a gift that can be given all-year-round.

59.People use social networking sites such as Twitter and Facebook toD.
A.obtain information                       B.give attention to others
C.voice their opinions                     D.notice and get noticed
60.What can we infer from Paragraphs 6-7?D
A.More people will risk attention-starvation in future.
B.The nature of attention exchange is rarely changed.
C.Technological advancement contributes to all diseases.
D.Transformed attention exchanges do harm to society.
61.The writer's purpose for writing the passage is toA.
A.a(chǎn)dvocate more focus on real life attention  
B.a(chǎn)nalyze the necessity of attention giving
C.give practical tips on attention exchange   
D.recommend some social networking sites.

17.My favorite English teacher could draw humor out of the driest material.It wasn't forced on us either.He took Samuel Johnson's dictionary,Addison's essays,and many other literary wonders from the eighteenth century and made them hilarious,even at eight o'clock in the morning.The thing that amazed me most was that the first time I read these works on my own some of them seemed dead,but the second time,after his explanation,I couldn't believe that I hadn't seen the humor.The stories and poems and plays were suddenly filled with allusions(典故) and irony and hilarious moments.I learned more from him than from any other teacher.
My least favorite English teacher also made people laugh.Some students found him to be wonderfully funny.Many others did not.He assigned journals over a six week period,to be written in every day.At the end of the six weeks I had a notebook full of bits and pieces about my ideas,short stories,reactions to what we had read,and so on.Our teacher announced that we would be grading each other's journals.Mine was passed to Joe,that class clown,who always behaved in a funny or silly way.He saw it fit to make joke of and said,"This writing isn't fit to line the bottom of a birdcage."Our teacher laughed at that funny remark.It hurt me so much that the anger from it has driven my writing and teaching ever since.
So what makes the difference?Humor is one of the most powerful tools teachers or writers have.It can build up students and classes and make them excited about literature and writing,or it can tear them apart.It is true that humor is either productive or counter-productive and self-defeating.

59.The passage mainly discussesC.
A.teaching      B.literature     C.humor     D.knowledge
60.The underlined word"hilarious"in Paragraph 1probably meansA.
A.funny      B.tiring       C.inspiring    D.brilliant
61.With his favorite English teacher,the writer found it most amazing thatC.
A.his teacher was very learned
B.his teacher was very humorous
C.the works by Johnson and Addison were very humorous
D.few were able to find humor in works by Johnson and others
62.The English teacher the writer disliked mostB.
A.was not able to make students laugh
B.hurt his students'feelings
C.didn't let his students do the grading
D.had no sense of humor.

15.A funny thing happened on the way to the communications revolutions:we stopped talking to one another.
  I was walking in the park with a friend recently,and his cell phone rang,interrupting our conversation.There we were,walking and talking on a beautiful sunny day and…I became invisible(看不見(jiàn)的),absent from the conversation.
  The telephone used to connect you to the absent.Now it makes people sitting next to you feel absent.Why is it that the more connected we get,the more disconnected I feel?Every advance in communications technology is a tragedy to the closeness of human interaction.With email and instant messaging over the Internet,we can now communicate without seeing or talking to one another.With voice mail,you can conduct entire conversations without ever reaching anyone.If my mom has a question,I just leave the answer on her machine.
  As almost every contact we can imagine between human beings gets automated,we are now feeling more distant from one another.You can't even call a person to get the phone number of another person any more.Directory assistance is almost always fully automated.
  I am not against modern technology.I own a cell phone,an ATM card,a voice mail system,and an email account.Giving them up isn't wise…they're a great help to use.It's some of their possible consequences that make me feel uneasy.
  More and more I find myself hiding behind e-mail to do a job meant for conversation,or being relieved that voice mail picked up because I didn't really have time to talk.The industry devoted to helping me keep in touch is making me lonelier.
  So I've put myself on technology restriction:no instant messaging with people who live near me,no cell phoning in the presence of friends,no letting the voice mail pick up when I'm at home.
64.Which of the following would be the best title of the passage?B
A.The Advance of Communications Technology.
B.The Consequences of Modern Technology.
C.The Story of Communications Revolution.
D.The Automation of Modern Communications
65.The sentence"Now it makes people sitting next to you feel absent,"means thatC.
A.the people sitting beside you have to go away to receive a phone call
B.you can hardly get in touch with the people sitting beside you   
C.modern technology makes it hard for people to have a face-to-face talk   
D.people can now go to work without going to the office
66.The writer feels that the use of modern communications isD.
A.encouraging       B.disappointing    C.satisfying      D.embarrassing 
67.The passage implies thatA.
A.modern technology is separating the people     
B.modern technology is bridging the people.
C.modern technology is developing too fast
D.modern technology is interrupting our communications.
