其實(shí)從語法上來說,兩個(gè)都是行的,不過運(yùn)用到的知識(shí)點(diǎn)不一樣而已1.we think that is necessary 我們認(rèn)為那是有需要的.主語 we 謂語 think 賓語從句 that is necessary.that在從句中充當(dāng)主語,是一個(gè)代詞,代指“那個(gè),那...I could't understand【 what 】was the matter with me.還是…what the matter was with me這里 I couldn't understand后面what引導(dǎo)一個(gè)賓語從句，賓語從句后面的語序是陳述的，而遇到the matter 時(shí)，比較特殊，有兩種情況。1. 語序是 what was the matter 時(shí)，意思是“有什么問題”， 主語是what, 賓語是was2. 語序是 what the matter was時(shí)，意思是“這物質(zhì)是什么”，主語是the matter“這物質(zhì)”， 謂語是was而這里有個(gè)with me,根據(jù)句意，是“我出什么問題了”，所以是 I couldn't understand what was the matter with me. /I couldn't understand what was wrong with me.
