【題目】—When ________ the first practical light bulb ________?

—In 1879.

A.does; inventB.is; inventedC.did; inventD.was; invented

【答案】D

【解析】

句意:——第一款實(shí)用的電燈泡什么時(shí)候發(fā)明的?——1879年。

考查一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)。A選項(xiàng)是一般現(xiàn)在時(shí);B選項(xiàng)是一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài);C選項(xiàng)是一般過(guò)去時(shí);D選項(xiàng)是一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)。根據(jù)回答“In 1879.”可知問(wèn)句是詢問(wèn)過(guò)去的事情,用一般過(guò)去時(shí),排除AB;“電燈泡”與發(fā)明之間是被動(dòng)關(guān)系,因此用一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)。故選D。
