You _ a lot of sugar in it. A. should put B. could have put C. might put D. must have put分析：答案選D。前文說“蛋糕很甜”，下文“你一定是在里面放了很多糖”，故用“must have d

36、one”表示對過去情況的肯定推測。對現(xiàn)在或將來的推測常用結構為：情態(tài)動詞+_/_對過去情況的推測常用結構為：情態(tài)動詞+_ 如：dobe doinghave done第四十五張，PPT共五十六頁，創(chuàng)作于2022年6月(1) Catherine, I have cleaned the room for you.Thanks. You _it.
