1.兩者不一樣.
2.no matter who引導(dǎo)的只能是讓步狀語(yǔ)從句,在句子做狀語(yǔ),對(duì)句子其他主要成分如主語(yǔ)/謂語(yǔ)沒(méi)有任何影響.
如：No matter who is on duty today,he must clean up the classroom.
3.但是whoever有兩種理解.
1）whoever = no matter who,同樣引導(dǎo)讓步狀語(yǔ)從句.
如：No matter who is on duty today,he must clean up the classroom.
= Whoever is on duty today,he must clean up the classroom.
2）whoever還可以用來(lái)引導(dǎo)名詞性從句,包括主語(yǔ)從句/賓語(yǔ)從句/表語(yǔ)從句/同位語(yǔ)從句.
此時(shí),whoever = anybody who,翻譯成“任何...的人”.
3）該題恰恰是用whoever引導(dǎo)一個(gè)主語(yǔ)從句,做句子的主語(yǔ).
即：(Whoever leaves the room last) should remember to turn off the light.主語(yǔ)從句
= Anybody (who leaves the room last) should remember to turn off the light.定語(yǔ)從句
