Question

13．他無法證明他不在案發(fā)現(xiàn)場(chǎng)．He can't prove he was not at the scene of the crime．．

Answer 1

分析 He can't prove he was not at the scene of the crime．

解答 答案：He can't prove he was not at the scene of the crime．這里需要用含有賓語(yǔ)從句的主從復(fù)合句來表達(dá)，主句是他無法證明，說的是客觀事實(shí)用一般現(xiàn)在時(shí)，主語(yǔ)he，不能can't，情態(tài)動(dòng)詞后加動(dòng)詞原形prove證明，后加上that引導(dǎo)的賓語(yǔ)從句，that可以省略，主句時(shí)態(tài)是一般現(xiàn)在時(shí)，從句時(shí)態(tài)不受限制，從句是他不在案發(fā)現(xiàn)場(chǎng)，是說過去，故用一般過去時(shí)，主語(yǔ)he，不再was not at，at接小地點(diǎn)，案發(fā)現(xiàn)場(chǎng)the scene of the crime，故答案是He can't prove he was not at the scene of the crime．

點(diǎn)評(píng) 本題旨在考查賓語(yǔ)從句這一語(yǔ)法，做這類題時(shí)，要從三方面考慮：一、選準(zhǔn)連接詞 二、連接詞后緊跟從句的主語(yǔ) 三、若主句是過去時(shí)，從句要改為相對(duì)應(yīng)的過去時(shí)．
