Question

It was ______ the president's speech that the secretary spent the whole morning at home.

A．to prepare

B．preparing

C．prepared

D．be prepared

Answer 1

B

本題考查非謂語動詞。去掉It was…that后剩下的部分為______ the president's speech the secretary spent the whole morning at home，調(diào)整結(jié)構(gòu)后是the secretary spent the whole morning at home ______ the president's speech。結(jié)合選項(xiàng)可知句意是：秘書花了整個早上在家為總統(tǒng)準(zhǔn)備演講。由此判斷考查的是spend time （in）doing sth句型。
