When your friends are in trouble,you shonld do all__________
When your friends are in trouble,you shonld do all___________them. A.you can help B.you can to help C.that you can help D.what you can help 重在讲解,不在答案(越具体越好)
选B 翻译:当你的朋友有难时,你应该尽力去帮助他们。 (When your friends are in trouble)是时间状语从句。后面从句还原:...do all (that) you can to help them,其中“that you can”是定语从句修饰“all”。“to help” 表示一种目的,作补语。
B, do (that) all you can 中,all you can是do 的宾语,that 可省略,to help them 是DO ALL YOU CAN 后面加的不定式! C 应改为 do that you can to help D 应改为 what you can do to help 希望能帮到楼主!
