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(shí)間狀語at that moment那時(shí)，可知從句描述的是過去某時(shí)發(fā)生的動(dòng)作，故用一般過去時(shí)態(tài)。故選A。
考點(diǎn)：賓語從句及時(shí)態(tài)
點(diǎn)評(píng)：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(shí)，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(jìn)行具體分析。賓語從句的時(shí)態(tài)和主句沒有必然的聯(lián)系，需結(jié)合語境具體分析。
