- whether怎么用
- whether和if的意思相同,都是引导名词从句的连词,一般情况下可以互换使用。
但在下列情况下,whether不能if被取代:
1) whether引导主语从句并在句首时;
e.g. Whether the plan is feasible remains to be proved.
2)whether引导表语从句时(因为if不能引导表语从句);
e.g. The point is whether we should lend him the money.
3)whether从句作介词宾语时;
e.g. I worry about whether he can pass through the crisis of his illness.
4)从句有"or not"时.
e.g. I don't care whether you like the plan or not.
