        1. 【題目】I wonder why Jenny ________us recently.We should have heard from her by now.

          A. hasn’t written B. doesn’t write

          C. won’t write D. hadn’t written

          【答案】A

          【解析】

          考查時(shí)態(tài)。句意:我想知道為什么Jenny最近沒(méi)有寫信給我們。到目前為止我們應(yīng)該已經(jīng)收到她的來(lái)信了。副詞recently意為“最近,近來(lái)”,通常與現(xiàn)在完成時(shí)連用。本句主語(yǔ)是Jenny,謂語(yǔ)動(dòng)詞要使用第三人稱單數(shù),故A項(xiàng)正確。
