16.The engine just won't start.Something seems             wrong with it.( 。
A.to goB.to have goneC.goingD.having gone

分析 發(fā)動機就是發(fā)動不起來了.好像是出毛病了.

解答 答案:B.
動詞seem后常接動詞不定式,因此C、D兩項不正確.由句意可知,go這一動作在start之前發(fā)生,表示問題已經(jīng)在發(fā)動機發(fā)動不起來之前就已經(jīng)出現(xiàn)了,所以用完成時;故選B.

點評 熟練掌握動詞不定式的用法,了解現(xiàn)在時和完成時之間的差別.
