—What do you think of genetically modified food (轉基因食品)?

  —We all think ______ is careless ______ some scientists to say it is safe before doing any experiment.

A. that, for                            B. it, for                                 C. it, of                                  D. that, of

 

【答案】

C                

【解析】             

試題分析: 考查代詞與介詞。句意:你認為轉基因食品如何呢?我們一直認為科學家在做實驗之前說這是安全的,這事是很粗心的。考查it be +adj+of sb to do,it做形式主語,真正的主語是后面的不定式,of用來表達某人品質或特性, 所以選C項。         

考點:考查代詞與介詞。

     People have sailed (航行) around the world in quite small boats.  It is not an easy thing to do.
Sometimes the weather gets bad.  That can be the end of a boat, and the end of everyone in it.  
Accidents can happen easily and quickly.
     One family once had an accident with some big fish.  The fish swam under their boat and bit (咬) holes
in it.   The sea water came in,  of course,  and the boat soon sank (沉沒).  Hr,  these people had another
small boat-a lifeboat,  and they all got into that.  They lived and hoped for many days.  They ate and
slept, and they always hoped.  At last a ship found them.
