非谓语结构
非谓语形式包括 to + V,V-ing, V-ed,甚至没有动词。
非谓语结构使用的几条原则:
看标点符号是否逗号,看是否有连词,看是否是非限制性定语从句。
非谓语结构前后主语保持一致才能被省略。
非谓语结构选择依据:
1)首先判断是否选择 to + V:* 不定式一般表目的(* I have something to do/ need a room to live in. * He is always the first / last to arrive. * I got there only to find the train had gone.)其余的选择V-ing 或V-ed
2) 根据主动还是被动选择V-ing 还是V-ed。
3) 选择正确的时态。
4) 否定词放在非谓语结构前面。
