Use your head.Nothing taught by others can have the same effort on you as _____ is learned by yourself.

A.those B.what C.that D.the one

我選了B，可答案是C，想知道為什么，請詳述。

抱歉我確實打錯了原題應(yīng)是

Use your head. Nothing taught by others can have the same effect on you as _____  learned by yourself.　　

A.those          B.what            C.that             D.the one　　但我覺得

what learned by yourself也應(yīng)該是對的，要是不對你能告訴我為什么嗎？

Use your head. Nothing taught by others can have the same effect on you as _____  learned by yourself.　　

A.those          B.what            C.that             D.the one　　

如果這是正確的原題（而不是你打錯了的），那么，答案是C。

問題的關(guān)鍵是：

that是代詞，用來指代與前面同類的事物（這類事物是單數(shù)意義），它跟nothing是一個類別，后面的過去分詞短語都是作定語。

what是連接代詞，也叫復(fù)合關(guān)系代詞，相當(dāng)于the thing that 或 anything that。它是引導(dǎo)句子的，具體說，是引導(dǎo)名詞性從句的，它在從句中要做成分的：主語，賓語或表語。例如：What you said is right. What is learned in the textbooks is not quite practical.
