Question

【題目】I was listening to music my English teacher came in.

A. until B. while C. since D. when

Answer 1

【答案】D

【解析】

句意：當(dāng)我的英語老師進(jìn)來時(shí)，我正在聽音樂。until直到，while表示在……時(shí)候，與延續(xù)性動(dòng)詞連用；since自從，與現(xiàn)在完成時(shí)連用；when當(dāng)……時(shí)候，引導(dǎo)的從句用瞬間性動(dòng)詞，主句用進(jìn)行時(shí)。根據(jù)主句I was listening to music可知此處用when引導(dǎo)的時(shí)間狀語從句，故選D。
