Question

I often hear him ______.Today when I pass(經過)the classroom, I hear him ______again .

A．sing; singing	B．singing; sing
C．singing; singing	D．sing; sing

Answer 1

A

試題分析：句意：我常常聽到他唱歌。今天當我經過教室的時候，我聽到他又唱歌了。hear sb do sth 聽見某人做某事，hear sb doing sth聽見某人正在做某事，題中有when I pass(經過)the classroom當我經過教室時，這個時間狀語，故選A
點評：hear sb do sth /hear sb doing sth的區別在英語中這類動詞的句型非常常見，常見的還有see sb do sth看見某人做某事 /see sb doing sth看見某人正在做某事，前者強調動作的全過程，后者強調正在進行。
