◎用法總結:whether/if表示“是否”相同點和不同點:相同點二者在引導賓語從句時一般可以互換。如:Iwonderif/whetherKatewilletomyparty.我想知道凱特是否會來我的聚會。不同點whether后可以接or或ornot,而if則不能。如:Idon'tknowwhetheryouarerightornot.我不知道你是否正確。whether可以用在不定式前,而if則不能。如:Anncan'tdecidewhethertobuyahousethisyear.安不能決定今年是否買房。whether可以用在介詞后。而if則不能。如:Myuncleisthinkingaboutwhetherheshouldbuyacar.我叔叔在考慮是否應該買小汽車。if除了表示“是否”,還有“如果”的意思,而whether沒有。如:Ifit'srainytomorrow,I'llnotclimbmountains.如果明天下雨,我就不去爬山。對點自測用whether或if填空1.—Willyout
