(2)It is to be decided whether to go or stay here.

是走还是呆在这儿还有待决策。(it作形式主语。)

(3)Will you advise me whether to accept his suggestion (or not)?

(2)You may rely upon my help, whether others help you or not.

(2)The question whether we ought to call in a specialist was answered by the family doctor.

作“是否,会不会”解时,whether可用来引导名词性从句,即主语从句、宾语从句、表语从句和同位语从句。【第四篇】

1、 引导主语从句。引导主语从句时,可用it作形式主语。例如:

(1)Whether they consider this opinion or not is not clear. (= It is not clear whether they consider this opinion or not. )

他们是否考虑这个意见还不清楚。

(2)Whether we shall be able to come is doubtful. (= It is doubtful whether we shall be able to come. )我们是否能够来,尚不确定。

2、 引导宾语从句。这时whether可与if换用。例如:

(1)A simple experiment will show whether air has weight or not. (= A simple experiment will show if air has weight. )一个简单的实验就可以证明空气是否有重量。

(2)I wonder whether we shall be in time for the last bus or (whether we shall)have to walk home.
