They hoped to have stayed there a week, but they couldnt because of another important meeting. 9．现在表将来类 这类动词(词组)常用一般现在时或现在进行时表将来。它们是：come, go, leave, start, arrive, move, begin, fall, see, stay, take off等。如： Your plane takes off at a quarter past two in the afternoon. 你的飞机是下午二点一刻起飞。 I am coming to that. The National Day is drawing near. 10．带介词to的动词短语 带介词to的动词短语有：be (get) used to, lead to, devote…to, look forward to, stick to, object to, get down to, adapt to等。后面的动词要用v.- ing形式。 几组常错常考动词的词形变化 实为及物动词却常被误为不及物动词： 8.以get为中心 get about 徘徊,走动,流传 get across 使被理解 get along 前进,进步,离去,相处 get around 走动,传播 get away 离开,逃脱 get back 取回,回来,报复 get down to 认真对待,静下心来 get out of
