I hope that it will be sunny tomorrow
這里不用which,這是一個賓語從句,從句中不缺任何成分,只能用that引導(dǎo)賓語從句.
由連接詞that引導(dǎo)賓語從句時,that在句中不擔(dān)任任何成分,在口語或非正式的文體中常被省去,
例如：
He has told me that he will go to Shanghai tomorrow.他已經(jīng)告訴我他明天要去上海.
which 基本釋義：
pron.哪/那一個；哪/那一些
adj.哪一個；哪一些哪種賓語從句中用which。謝謝賓語從句which是一個連接代詞,在賓語從句中可以充當(dāng)主語，賓語或定語。意思是“哪一個，那些”如：I don't know which bike belongs to my father. I wonder which is better ,this one or that one? He asked me which I liked best. I don't know which book is yours.我不知道那本書是你的 He asked which books were his 他問那些書是他的
