2. 有些时间、地点、条件、方式或让步从句,如果从句的主语与主句主语一致(或虽不一致,是it),从句的谓语又包含动词be,就可省略从句中的“主语 + be”部分。 e.g. When (he was) still a boy of ten, he had to work day and night. If (you are) asked you may come in. If (it is) necessary I’ll explain to you again. 3. 注意区分不同从句:引导的是什么从句,不仅要根据连词,还要根据句子结构和句意来判别。以where为例,能引导多种从句。 e.g. You are to find it where you left it.(地点状语从句) Tell me the address where he lives.(定语从句,句中有先行词) I don‘t know where he came from.(宾语从句) Where he has gone is not known yet.(主语从句) This place is where they once hid.(表语从句) (责任编辑:admin) |
