18．        it contains enough iodine to block radiation，many people bought large quantities of iodised salts in China．（　　）
A．BelievingB．Believed
C．Being believedD．Having been believed

分析 由于相信鹽里面含有足夠的碘能夠阻隔輻射，在中國，很多人購買了大量的加碘食鹽．

解答 答案：A
分析句意可知，"it contains enough iodine to block radiation"在句中作原因狀語，動詞believe與其邏輯主語many people 構(gòu)成主謂關(guān)系，故用現(xiàn)在分詞作狀語表示原因；C 現(xiàn)在分詞被動語態(tài)的一般式 D 現(xiàn)在分詞被動語態(tài)的完成式，以上兩個選項都表示被動關(guān)系，用在此處不合句意，故選A

點(diǎn)評 本題考查了現(xiàn)在分詞作原因狀語的用法．做本題時，首先應(yīng)根據(jù)句意，判斷選項中的動詞與其邏輯主語的關(guān)系；其次應(yīng)掌握現(xiàn)在分詞，現(xiàn)在分詞被動語態(tài)的一般式以及現(xiàn)在分詞被動語態(tài)的完成式之間的用法區(qū)別．

8．I'm not so sure I like my friends any more．I used to like them-to be honest．We'd have lunch，talk on the phone or exchange emails，and they all seemed normal enough．But then came FaceBook，and I was introduced to a sad fact：many of my friends have dark sides that they had kept from me．
Today my friends show off the more unpleasant aspects of their personalities via FaceBook．No longer hidden，they're thrown in my face like TV commercials-unavoidable and endless advertisements for the worst of their personalities．
Take Fred．If you were to have lunch with him，you'd find him warm，and self-effacing（謙遜的）．Read his FaceBook and you'll realize he's an unbearable，food-obsessed boring man．He'd pause to have a cup of coffee on his way to save a drowning man-and then write about it．
Take Andy．You won't find a smarter CEO anywhere，but now he's a CEO without a company to run．So he plays Mafia Wars on FaceBook．He's doing well-level 731．Thanks to FaceBook，I know he's playing about 18hours a day．Andy，you've run four companies-and this is how you spend your downtime？What happened to golf？What happened to getting another job？
Take Liz．She is positive that the flu vaccine will kill us all and that we should avoid it．And then comes Chris who likes to post at least 20times a day on every website he can find，so I get to read his thoughts twice，once on FaceBook and once on Twitter．
In real life，I don't see these sides of people．Face to face，my friends show me their best．They're nice，smart people．But face to FaceBook，my friends are like a blind date which goes horribly wrong．
I'm left with a dilemma．Who is my real friend？Is it the Liz I have lunch with or the anti-vaccine madman on FaceBook？Is it the Fred I can grab a sandwich with or the Fred who weeps if he's at a party and the wine isn't up to his standards？

26．Who is opposed to the flu vaccine in the text？C
A．Fred．            
B．Andy．        
C．Liz．       
D．Chris．
27．What's Andy probably busy in doing now？D
A．He's running his company．    
B．He's playing golf all day．
C．He's looking for another job．    
D．He's playing computer games．
28．According to the text，F(xiàn)aceBook tends toA．
A．present another side of people      
B．offer some foods for free
C．show endless advertisements       
D．get you to more parties
29．What does"it"underlined in the last paragraph refer to？B
A．a(chǎn) dilemma         
B．my real friend    
C．Facebook    
D．Twitter
30．The text is developed mainly byA．
A．giving examples                 
B．following the time order
C.1isting figures                   
D．raising questions．

6．閱讀下面短文，然后按要求寫一篇150詞左右的英語短文．
Once upon a time in a land far away，there was a wonderful old man who loved everything：animals，spiders，insects…
One day while walking through the woods the nice old man found a cocoon（繭）of a butterfly．He took it home．A few days later，a small opening appeared； he sat and watched the butterfly for several hours as it struggled to force its body through that little hole．Then it seemed to stop making any progress．It appeared as if it had gotten as far as it could and it could go no farther．
Then the man decided to help the butterfly，so he took a pair of scissors and cut off the remaining bit of the cocoon．
The butterfly then came out with ease．
But it had a swollen body and small，shriveled（萎縮的）wings．The man continued to watch the butterfly because he expected that，at any moment，the wings would enlarge and expand to be able to support the body．Neither happened!In fact，the butterfly spent the rest of its life crawling around with a swollen body and shriveled wings．It never was able to fly．
What the kind-hearted man did not understand was that the restricting cocoon and the struggle required for the butterfly to get through the tiny opening were Nature's way of forcing fluid（液體）from the body of the butterfly into its wings so that it would be ready for flight once it achieved its freedom from the cocoon．
Sometimes struggles are exactly what we need in our life．If we were allowed to go through our life without any hardships，it would fail us．We would not be as strong as what we could have been．And we could never fly．
寫作內(nèi)容
1．以約30個詞概括上文的主要內(nèi)容．
2．以約120個詞就"個人成長需要艱難生活的磨礪"的主題發(fā)表看法，至少包含以下內(nèi)容要點(diǎn)：
（1）你讀了這個故事的感受；
（2）敘述當(dāng)前父母溺愛子女的現(xiàn)象和由此造成的后果；
（3）假如你是父母的一方，你會如何磨礪自己的孩子？
寫作要求
1．你可以使用實例或其他論述方法支持你的觀點(diǎn)，也可以參照閱讀材料的內(nèi)容，但不得直接引用原文中的句子．
2．作文中不能出現(xiàn)真實姓名和學(xué)校名稱．
評分標(biāo)準(zhǔn)
概括準(zhǔn)確，語言規(guī)范，內(nèi)容合適，語篇連貫．
A kind man cut a cocoon open in order to lessen the pain of a butterfly when he saw it struggling out of the cocoon，only to find that it could never fly because of his help．
The story sets me thinking．Our life is more or less like this．Sometimes，struggles or obstacles in our life are a must for our growth．It is these struggles or obstacles that increase our willpower and contribute to our success．Without these trials，we could never achieve our life goal just as the butterfly did in the story．
Nowadays，with only one child in most families，parents do whatever they can to satisfy the child's needs and even do for him what should be done by himself．Consequently，the child is unable to look after himself without his parents'presence．Too much care from parents deprives children of chances to grow strong by conquering obstacles．
　 If I were a parent，I would first keep him well informed that life is never easy and that he should be ready to face any difficulties．Besides，I would expose him to the hardships in life instead of protecting him from difficulties，providing them with chances to fight for his bright future by conquering challenges．．
