Question

【題目】There was a time _______, if a lady got onto a crowded bus or train, a gentleman would immediately stand up and offer her his seat.

A.whileB.asC.whenD.unless

Answer 1

【答案】C

【解析】

考查關(guān)系副詞。句意：曾經(jīng)有一段時(shí)間，如果女士上了擁擠的公共汽車或火車，男士會立即站起來給她讓座。表示“曾經(jīng)有一段時(shí)間”是there was a time when，先行詞是time，在定語從句中作時(shí)間狀語，用when引導(dǎo)定語從句。故選C。
