【題目】Many students are at a loss as to _________ they spend so much time on language learning, but achieve little.

A. that B. why C. how D. which

【答案】

【解析】

試題分析:考查名詞性從句。句意:很多學(xué)生感到困惑的是為什么他們在語言學(xué)習(xí)上花費了如此多的時間但收效甚微。分析句子結(jié)構(gòu)可知,空處在此引導(dǎo)從句作as to 的賓語,且引導(dǎo)詞在從句中充當(dāng)原因狀語,故用why。故選B項。
