1、在并列句中,为了避免与第一个分句的相同内容重复,可采用省略谓语,而保留主语和表语或补足语等成分。
2、在定语从句中,当先行词在句中作宾语时,可省略关系代词that/whom.例如:
They talked about the things and people (that) they remembered.
The doctor did everything (that) he could to save the patient.
3、宾语从句中的省略在含有动词“命令(order, command), 建议(suggest, propose),要求(request, demand, require),坚持(insist)希望(desire)”等的名词性从句中,谓语动词通常用should 动词原形,而且should可被省掉。例如:
It is desired that this rule(should)be brought to the attention of the staff. They suggested that he (should) go on a summer camp.
4、在表示时间、条件、地点、让步、方式或比较的状语从句中,如果包含动词be,从句中的主语与主句相同,或者从句的主语为it,就常常把从句中的主语和谓语的一部分(动词be)省略掉,只保留连词 现在分词/过去分词/形容词。
5、动词不定式的省略在上下文中,为了避免重复前面或后面出现的动词和动词短语,通常在一些包含有动词不定式的结构中,将动词不定式省略,只保留动词不定式符号to.例如:
1)I can‘t stand as much as I used to.
2)Jack didn’t pass the driving test,but he still hope to.
3)Mary wanted to use your new bike,but I asked her not to.
