Question

Perseverance is a kind of quality --- and that’s ________ it takes to do anything well.

A．why

B．that

C．which

D．what

Answer 1

D

試題分析：考查表語從句：句意：堅(jiān)持是一種品質(zhì)，這是把事情做好必須的。Is后面是表語從句，take后面是缺少賓語，用what引導(dǎo)表語從句。選D。
點(diǎn)評：連接表語從句的連接詞有：that, what, who, when, where, which, why, whether, how, whoever，whomever，whichever ，whatever等。還有如because, as if, as though等。解答這類題目，關(guān)鍵在于分析清楚句子結(jié)構(gòu)。通過判斷引導(dǎo)詞在從句中所作的成分及意義，來選擇正確的引導(dǎo)詞。
