        1. 【題目】We ________ each other since I came to Beijing, but we send emails very often.

          A.don't seeB.didn't seeC.won't seeD.haven't seen

          【答案】D

          【解析】

          句意:自從我來(lái)北京,我們就沒(méi)見(jiàn)過(guò)面,但我們經(jīng)常發(fā)電子郵件。

          本題考查時(shí)態(tài)。don't see是一般現(xiàn)在時(shí);didn’t see是一般過(guò)去時(shí);won’t see是一般將來(lái)時(shí);haven’t seen是現(xiàn)在完成時(shí)。根據(jù)since I came to Being可知,此處用現(xiàn)在完成時(shí),故選D。
