Question

I__________ you somewhere before, but your name has escaped me_________.

A. must see; for a moment          B. must have seen; for a moment

C. must see; for the moment        D. must have seen; for the moment

Answer 1

D

解析:

almost與不定式的完成時(shí)連用表示對過去發(fā)生的事持肯定態(tài)度的推斷，在疑問句中用can，在持否定態(tài)度的推斷時(shí)用can not。for a moment表示一個(gè)動作延續(xù)了一會兒，而for the moment則表示“目前；暫時(shí)”。
