Question

【題目】If he____ to the teacher attentively, he____the answer to the problem now.

A.had listened, would have knownB.listened, would know

C.listened, would have knownD.had listened, would know

Answer 1

【答案】D

【解析】

考查虛擬語(yǔ)氣。句意：如果他專心聽(tīng)了老師的話，他現(xiàn)在就會(huì)知道問(wèn)題的答案了。結(jié)合句意，此處是if引導(dǎo)的虛擬語(yǔ)氣，從句與過(guò)去的事實(shí)相反，主句與現(xiàn)在的事實(shí)相反，所以這里是混合虛擬語(yǔ)氣。故選D。
