非谓语动词作主语时要注意以下两个重要问题:
1.并行结构问题,
Seeing is believing. / To see is to believe.
2.需要注意一些结构:
A) 在 It’s no use (good; value; importance) 等结构中只用动名 词作主语。如:It’s no use quarrelling with such a fellow . 注意比较:There’s no need to tell him about it.
B. seized.., disappeared
C. seizing, disappearing D. seized, disappearing
seized 和 took 是并列谓语,disappearing 是伴随状语。此题的关 键是and 的位置,如果 and 在 disappear 前,则三个动词并列。
