Question

【題目】He pretended when his mother stepped into his room.

A. to study B. studying

C. to be studying D. to have studied

Answer 1

【答案】C

【解析】

考查不定式用法。不定式的一般式to do說(shuō)明該動(dòng)作在謂語(yǔ)動(dòng)詞之后發(fā)生；進(jìn)行時(shí)to be doing表示兩者同時(shí)發(fā)生；to be done表示被動(dòng)。句意：當(dāng)他的媽媽走進(jìn)房間的時(shí)候，他假裝在睡覺(jué)。根據(jù)句意說(shuō)明兩個(gè)動(dòng)作同時(shí)發(fā)生，故使用不定式的進(jìn)行時(shí)。故C正確。
