解答 We've had a discussion about whether cloning should be carried out.Opinions are divided on the question.
      About 35 percent of the students think there are more advantages.First of all,cloning can be used in the medical field.Scientists can clone healthy cells,which can help doctors cure patients.(高分句型一)Also,cloning extinct animals has always excited scientists.Another advantage of it is increasing agricultural output,which is of great importance in our country.(高分句型二)
      However,about 65 percent of students hold the opposite view.For example,there is doubt about whether cloning is moral.Furthermore,diversity in genes is essential for animals to overcome diseases.A group of cloned animals would all have the same arrangement of genes.What's worse,if the technology of cloning is taken advantage of by evil leaders,it will be very dangerous.(高分句型三)

點評 英語寫作是一項主觀性較強的測試題.它不僅考查學生的寫作基礎(chǔ)而且還考查學生在寫作過程中綜合運用語言的能力.在撰寫時要注意主謂語一致,時態(tài)呼應(yīng),用詞貼切等.要提高英語寫作水平,需要兩方面的訓練:一是語言基礎(chǔ)方面的訓練,要有扎實的造句、翻譯等基本功,即用詞法、句法等知識造出正確無誤的句子;二是寫作知識和能力 方面的訓練以掌握寫作方面的基本方法和技巧.

11.I was at Kendriya Vidyalaya in Bambolim,Goa,in the 1980s.On Inspection Day one year,an officer and his team from the Board of Education were coming to see how our school was run.As usual,our teachers asked us to be prepared.
At the end of the day,Mrs Sushila Tyaji,our Hindi teacher,walked in and told us that the inspector had come and qu ietly observed the class from the back door.He had also left an adverse remark!That was sad for us.Would we now be punished for having failed our teachers?There were no answers from Mrs Tyaji.Instead,she wrote the Hindi word"dukh"on the blackboard.And then she did something I have never seen a teacher do in my entire school life.She apologized.
"I am sorry for having taught you something wrong,"she said."I missed out the dots between the letters‘du'and‘kh'.The inspector told me this in the staffroom.I hope you will not make this mistake in future."
That admission had a significant effect on me.If our teacher can say sorry to us when she is wrong,why can't I?The incident helped me get rid of two common vices-ego and dishonesty.
Twenty-three years passed.I had to let my teacher know what that lesson meant to me.I recently located Mrs Sushila Tyaji using the Internet and went to meet her with my husband.
    She smiled when she heard my story of how her small decades-old apology had transformed me for good."It's tough being a teacher.But every once in a while,when an old student comes along and tells us that we did something right,it makes up for everything else,"she said.
4.The underlined word"adverse"in Paragraph 2 can be replaced by"B".
A.offensive         
B.unfavorable       
C.encouraging        
D.unforgettable
5.At the end of Inspection Day,Mrs TyajiC.
A.praised the students for their hard work
B.expressed her disappointment in the students
C.told the students that she had made a mistake
D.punished the students for their bad behavior
6.What did the author learn from Mrs Tyaji?A
A.Honesty is the best policy
B.Comfort is better than rude
C.One can never be too careful
D.It is better to be safe than sorry
7.The author's word during the visit made Mrs Tyaji feelB.

5.Old-Fashioned Play-For Pay
Kids!Come to have a ball!Or 60,000of them!There's a new type of business franchise(經(jīng)銷權(quán)) that is appearing in shopping malls and neighborhood across America offering pay-per-use indoor playgrounds,which feature toys,games,guided fun and a workout that doesn't break the family bank.
As public playgrounds grow increasingly worn and dirty,the for-profit centers offer clean,safe guided activity as well as a variety of challenging exercises to develop kids'physical fitness,usually for a fee of around $5an hour."Playgrounds are dirty,not guided,"says Dick Guggenheimer,owner of the two-month-old Discovery Zone in Yonkers,N.Y.,part of Kansas City-based chain,"We are indoors; we are padded;parents can feel their child is safe".
In order to satisfy the need of two-earner families,the new franchise stays open in the evenings,long after traditional public playgrounds have grown dark and unusable.However,these new playgrounds are not meant to be day-care centers.Parents are expected to go stay and play with their kids rather than drop them off.But several also provide high-tech baby-sitting services.At some of the Discovery Zones,parents can register their children in special guided programs,then leave them and slip away for a couple of hours to enjoy a movie or dinner.If there is a problem,Mum and Dad are called.
The most fun of all,though,is getting to do what parents used to do in the days before two-earner families and two-hour commutes,play with their kids.That,at least,is old-fashioned,even at per-hour rates.
29.What is this article mainly talking about?B
A.Children can play without parent's care
B.A new type of business franchise for kids.
C.The fast development of Discovery Zone
D.The disadvantages of outdoor playgrounds.
30.According to the article,which of the following is TRUE to the new playground?C
A.The cost is high for a family.
B.It doesn't allow parents to leave their kids.
C.It's a place where parents can play together with their kids.
D.It stays open in the evening just as traditional playgrounds.
31.The writer's attitude toward the new playground isC.
A.doubtful       
B.negative       
C.a(chǎn)greeable        
D.unknown.
