I have a suggestion that he (should） have a study plansuggestion建議,that同位語從句：用should have可省略shouldHis surprised look suggested he (had made)a mistakesuggested暗示,表明：賓語從句用陳述語氣...可選項只有to make,makes,make,made怎么辦？第一個填什么？為什么不能填made呢？i have a suggestion(to make). i have a suggestion that he (should make)a study plan第一個填to make是定語我要提一個建議。第二個填should make或make(should可省略）第三個made，但應(yīng)該填had made更好他臉上驚訝的表情表明他已經(jīng)搞錯了。表明suggested之前發(fā)生的make a mistake，所以用過去完成時更好?？蛇@個很容易搞混，第二個因為HE是第三人稱單數(shù)，所以用makes，啊should在這個句子形式中是肯定存在的嗎？你是高中在讀嗎？學(xué)習過虛擬語氣吧？第二個填should make或make(should可省略）因為suggestiong后的同位語從句用虛擬語氣，也就是should+動詞原形我有一個建議（就是）他應(yīng)該制訂一個學(xué)習計劃。（應(yīng)該：表示未發(fā)生的事）又如：I suggested he start right away.我建議他馬上出發(fā)（這是賓語從句的）What I suggested was that he start right away.我的建議就是他馬上出發(fā)（表語從句）都是省略了should
