A．what they were doing at that moment

D．what they are doing at that moment

Answer 1

A

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。
點評：賓語從句中一般為陳述語序，需注意當(dāng)疑問詞做從句主語時，則貌似倒裝句，需注意區(qū)分。關(guān)于引導(dǎo)詞的區(qū)分需結(jié)合引導(dǎo)詞的基本含義及其在句子中所承擔(dān)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(jié)合語境具體分析。
