解析試題分析：英語(yǔ)賓語(yǔ)從句中一般為陳述語(yǔ)序。根據(jù)從句中的時(shí)間狀語(yǔ)at that moment那時(shí)，可知從句描述的是過(guò)去某時(shí)發(fā)生的動(dòng)作，故用一般過(guò)去時(shí)態(tài)。故選A。
考點(diǎn)：賓語(yǔ)從句及時(shí)態(tài)
點(diǎn)評(píng)：賓語(yǔ)從句中一般為陳述語(yǔ)序，需注意當(dāng)疑問(wèn)詞做從句主語(yǔ)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(yǔ)從句的時(shí)態(tài)和主句沒(méi)有必然的聯(lián)系，需結(jié)合語(yǔ)境具體分析。
