题目内容
20.We can have_______ bluer sky if we create________ less polluted world.( )| A. | a;a | B. | a;the | C. | the;a | D. | the;the |
分析 如果我们创造一个少些污染的世界,我们可以拥有一个更蓝的天空.
解答 答案:A 根据题干及选项,可知本题考查冠词的用法.联系语境,这里的bluer sky,是指一片更蓝的天空,表泛指,所以用不定冠词a或an;如果用the就表示是一片特定的天空,可是因为天空只有一片,所以不需要表明特定.由于bluer是以辅音音素开头的单词,所以用a;其后的less polluted world也是同样的道理,这里指的是一个更少污染的世界,也是表泛指,所以也用a或an;由于less是以辅音音素开头的单词,故用a.综合起来,故选A.
点评 冠词类的题目一定要先把语境理解透彻,在此基础上运用规则确定冠词的种类;表泛指用a或an,表特指用the;并注意不定冠词的使用标准,注意细节.
