A. | presents | B. | has presented | C. | presented | D. | is presenting |
分析 该对话的大意是:A:李教授,你看起来很着急呀!B:我的助手此刻正在演讲大厅演讲,你知道她没有经验啦.
解答 答案:D.根据有空白的这句话句末有at the moment,它的意思是"此刻",可知她的助手做演讲的这个动作正在进行,故选择进行时态,只有D选项符合要求.
点评 该题考查现在进行时的用法,它表示正在进行的动作,而且常和look,listen,now,at the moment等连用. 这类题同学们要做好,关键要一:理解、掌握它的基本用法;二:它常与哪些时间状语连用;三:学会判断句中谓语动词发生在哪个时间(现在、过去、将来).只有这样,选择时才不会出错.
