Question

The teacher asked the students ________.

A．what they were doing at that moment

B．what were they doing at that moment

C．how are they doing at that moment

D．what they are doing at that moment

Answer 1

A

解析試題分析：英語賓語從句中一般為陳述語序。根據(jù)從句中的時間狀語at that moment那時，可知從句描述的是過去某時發(fā)生的動作，故用一般過去時態(tài)。故選A。
考點：賓語從句及時態(tài)
點評：賓語從句中一般為陳述語序，需注意當疑問詞做從句主語時，則貌似倒裝句，需注意區(qū)分。關于引導詞的區(qū)分需結合引導詞的基本含義及其在句子中所承擔的句子成分進行具體分析。賓語從句的時態(tài)和主句沒有必然的聯(lián)系，需結合語境具體分析。
