如果你滿意我的答案,這是對(duì)我們答題者勞動(dòng)的尊重,多謝!謝謝你的答案，和你的熱情。有些疑問(wèn)：（1）at night =in the night ，這個(gè)答案是否正確。（2）這句話是否等于“which your favorite subject ?"in the night勉強(qiáng)可以，不過(guò)其準(zhǔn)確意思是“在深夜”。不可以。樓主的變化句子中，連一個(gè)謂語(yǔ)動(dòng)詞都沒(méi)有。謝。那在which后面加is對(duì)么？應(yīng)該也可以，但是個(gè)人覺(jué)得沒(méi)有What is....好。謝謝。
