　　[点津]　现在分词作结果状语，是随着谓语动词的发生而产生的自然结果，其逻辑主语往往是前面整个句子所描述的情况，前面有时候可以加thus。而不定式作结果状语时常表示出乎意料的结果，有时前面可以加only。试比较：

　　He was caught in the rain, thus making himself catch cold．

　　被雨淋后他感冒了。

　　I hurried to school, only to find it was Sunday．

　　我匆忙赶到学校，结果发现是星期天。

　　5．作让步、方式和伴随状语

　　现在分词作让步、方式和伴随状语时，说明动作发生的背景和情况。作伴随状语时，表示分词的动作和主句的动作同时发生，此时它可转换成并列句。

　　Mary sat by the window of the classroom, reading a book．

　　＝Mary sat by the window of the classroom and was reading a book．

　　玛丽坐在教室的窗边读一本书。
