There is no doubt that IT plays___important role as a new teaching tool in this era of___technology.
A.an; B.; theC.an ; theD.;

答案
A
解析

试题分析:句意:毫无疑问,作为一种新的教学工具,IT在这个科技时代起着重要作用。这里that后引导的是同位语从句,第一空是固定短语play an important role起着重要作用;technology是不可数名词,前面不需要冠词,故选A。
点评:本题难度适中。冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。定冠词表特指,不定冠词表泛指。这里是考查冠词在固定短语中的用法。
即学即练:First impressions are the most lasting.After all,you never get________second chance to make________first impression.
A.a;the     B.the;the
C.a;a       D.the;a
解析:C。句意:第一印象最持久。毕竟,你不会再有机会去形成第一印象。第一空后有second,在此表示再一次机会,而不是表顺序,应用不定冠词;第二空中的第一印象是泛指,也不是表示顺序,又根据题干可以判断impression 在此处是可数名词,可数名词单数表泛指时须用不定冠词,故选C项。
