A.不填;不填B.不填; aC.the; aD.the; the

分析 当 Susan 盯着回收站里的塑料堆时,一种强烈的责任感使她将她的回收工作坚持了下来.

解答 答案:C
根据句意可知,第一个空表示特指"回收站里的塑料堆",故在piles of plastic 之前加定冠词the;第二个空表示泛指"一种强烈的责任感",因此在 strong sense of responsibility 前加a;故选C

点评 本题考查了冠词的用法;做本题时,需要根据句意判断出名词或名词短语的意义所指,即表示泛指还是特指;另外应熟练掌握定冠词,不定冠词以及零冠词的用法及区别.

1.Taking an exam has an evil twin called"cheating".And some Chinese and South Korean high school students have recently had a real taste of its bitterness(痛苦).
    They took the SAT,the US version of the college entrance exam,on Oct.11,expecting to get their results on Oct.30.However,what they found in their mailbox was an email saying that their test scores would be reviewed and delayed for up to a month because of accusation(指控) of cheating.An international official said that some students at the test centers in Asian countries had been caught checking their smart phones to get answers to SAT questio n while taking the exam.
     The incident has gotten worldwide attention as China and South Korean are the top two supplies of foreign university students in the US.If the cheating is confirmed,those students'scores could be cancelled,which worried many students,as Oct.11's test was the last SAT test this year and early applicants to US universities were due on Nov.1.
     However,the College Board,which developed the SAT,said that the review was to make sure that test-takers received valid(真实的) scores.Meanwhile,universities such as George Washington University have said that a delay in score reporting would not disadvantage applicants from those countries.
     Although there are more than 1,000 testing centers outside the US in more than 175 countries,the only testing allowed in China is at international schools,which means most Chinese students have to go to Hong Kong or another country to take the SAT.
      The problem of cheating in exams isn't unique to China.Last May,the College Board canceled an SAT testing date in South Korean after tutoring (辅导)companies were suspected to have illegally gotten SAT testing materials before the test.In 2011,twenty US students were arrested in Long Island,New York for hiring other students to take the SAT for them.

35.Why didn't the students get their test results on Oct.30?A
A.Because some students were dishonest in the exam.
B.Because some were accused of copying others'answers.
C.Because they did very badly in the exam.
D.Because they received the wrong email.
36.What may happen if the cheating is proved?C
A.They will lose many points.
B.The exam will be canceled for ever.
C.They will not be admitted to US universities.
D.They will be arrested by the US police.
37.If the scores prove valid,their admissions will be            according to the George Washington University.D
A.canceled         
B.delayed     
C.advanced        
D.unaffected
38.How many cases of cheating are ment ioned in the passage?B
A.Two.
B.Three.
C.Four.
D.Five.

8.Robots make me nervous-especially the ones which seem to think for themselves.I was embarrassed to admit this till I heard that Bill Gates,the founder of Microsoft,felt the same way.
Gates said in an interview with the social networking and news website Reddit:"I am in the camp that is concerned about super intelligence.First the machines will do a lot of jobs for us and not be super intelligent.That should be positive if we manage well.A few decades after that though the intelligence is strong enough to be a concern."
Well,maybe I don't have to worry about my computer and kitchen equipment yet.After I use them I can always pull the plug.But in the future,machines might find a way to prevent us from switching them off.There's a terrible thought!
Maybe the problem with computers too clever for us is not that they are evil like some we've seen in sci-fi movies.What could put us in danger is that they might be too efficient.That's what philosopher Nick Bostrom from Oxford University believes.He says that machines are indifferent(漠然)to humans and in pursuit of their own goals,the destruction of people might be just additional damage.Bostrom gives us an example:A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you.Because it is,well,a machine,it would not take pity on you.
It's a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics.They state that a robot may not hurt a human being or allow the human being to come to harm.
I'm glad my machines at home are"dumb".All my cleaner wants to take over is the carpet in my living room.Let's hope they don't create an appliance which wants to take over the world!.

28.The author quoted Bill Gates'words in Paragraph 2in order to make the textB.
A.better-known  B.more persuasive    C.better-organized   D.more interesting
29.An intelligent paperclip machine would harm us becauseC.
A.it is much cleverer than us
B.it would take over the world
C.it would see us just as material
D.it has the strong feeling of destroying us
30.How does the author feel about Isaac Asimov's rules of robotics?A
A.Optimistic.    B.Sympathy.    C.Disappointed.D.Regretful.
31.What does the text mainly focus on?C
A.The benefits of future robots.
B.The new applications of robots.
C.The concern for super intelligence.
D.The popularity of robots in the future.
