whether和if都是表示选择意义的引导词,一般来说,引出表示选择意义的宾语从句时,都可以用if或whether,二者没有什么区别。但是在某些特定情况中,我们该怎么办呢?这里我作了一个小结。1.引出主语从句并且位于句首时,通常用whether。如果将主语从句移至句尾,用先行词it作形式主语时,可以用if替换whether。比如:Whether (不可用if) she likes the present is not clear to me.=It’s not clear to me whether/if she likes the present.
Whether and if are guide words that represent meaning choices. In general, if you elicit an object clause that represents a meaning of choice, you can use if or whether or not. There is no difference between the two. But in certain circumstances, what should we do? Here I made a summary. 1. When the subject clause is quoted and is at the beginning of the sentence, usually use whether or not. If you move the subject clause to the end of the sentence and use the antecedent it as the subject of the form, replace if with if. For example: Whether (if not) she likes the present is not clear to me.=It’s not clear to me if/ if she likes the present.
