—Jane and July are here. Did I introduce them to you?
—No，you didn’t. I’ve seen them，but we__________.
A．hadn’t been introduced
B．haven’t been introduced
C．weren’t introduced
D．didn’t introduce
B

試題分析：考查時態(tài)。句意：—Jane和July在這里，我有沒有把他們介紹給你？—不，你沒有。我看見他們了，但是我們沒有被相互介紹。根據(jù)句意說明描述的是過去發(fā)生的事情對現(xiàn)在的影響，故使用現(xiàn)在進行時的被動語態(tài)。故B正確。
點評：現(xiàn)在完成時表示過去發(fā)生的事情對現(xiàn)在的影響，或者過去發(fā)生的事情延續(xù)到現(xiàn)在；而一般過去時只表示過去發(fā)生過某件事情，不表示對現(xiàn)在的影響。
