Question

After Yang Li Wei succeeded in circling the earth, _______ our astronauts desire to do is walk in space. 

A. where            B. what                C. that            D. How

Answer 1

B

解析:

主要測試主語從句。解答該試題的關(guān)鍵在于弄明白句子結(jié)構(gòu)。有語境可知該句子的結(jié)構(gòu)同上面兩道以下句子_______ our astronauts desire to do中缺少引導(dǎo)詞和動詞do的賓語即雙重作用。答案顯而易見。
