whether在这题引导名词从句,表是否能.的意思.此题大意是:他担心他是否能参加生日会.
以下资料供你参考:1.(引导名词从句)是否
Ask him whether he can come or not.问问他是否能来.
I don't know whether you like flowers,sir.
先生,我不知道您是否喜欢花.
2.(与or连用,引导状语从句)不管是...(或是)
We'll go on with the work,whether we can find the necessary tools or not.
不管我们能否找到所需的工具,我们要把这件工作做下去.
在引导定语从句时,一般情况下whether和if都可使用,但whether的适用范围要比if广,实在不知道应用什么的时候,选whether.
例如从句若出现了选择项:A or B,只能用whether而不能用if
但要注意,从句为否定句是,只能用if,而不能用whether
He worried about ()he would come to the birthday party.A.thatBwhatC.whoD.weather
He worried about ()he would come to the birthday party.A.thatBwhatC.whoD.weather
