可以有好幾個(gè)選擇,例如用：
1.that .比如：You should make sure that you know your duties well.你應(yīng)該要肯定自己知道要做什么.“that” 是用作連接下面的短語或者句子的.
2.which.比如：Please make sure which one is the right colour to paint.請(qǐng)注意（要肯定）那個(gè)顏色才是要上漆的.
3.who.比如：Please make sure who was the student to be given the prize.請(qǐng)確定哪個(gè)學(xué)生才是應(yīng)該得到獎(jiǎng)賞的.
其實(shí),連接詞像 where,when,what,why,how,how much 等等都可以拿來作為 跟隨 “make sure”的對(duì)象,具體要看語境和情景而定.
都是范例,不會(huì)那么詳細(xì).但是從應(yīng)用Usage 來說,所說的都可以運(yùn)用.可能是我表達(dá)清楚，如果其他動(dòng)詞要接wh-,how詞典上是要列出來的。怪就怪在make sure我查的牛津，朗文詞典都只列了that。很是奇怪。
