Question

Tom thought it was an honor ___________ to speak in the ceremony.

1. A.
   to invite
2. B.
   to be invited
3. C.
   inviting
4. D.
   having invited

Answer 1

B
考查it充當(dāng)形式主語(yǔ)。It是形式主語(yǔ)，Tom和invite構(gòu)成被動(dòng)的關(guān)系。to be invited to speak in the ceremony是真正的主語(yǔ)。句意：Tom認(rèn)為被邀請(qǐng)?jiān)趹c典上發(fā)言是一件光榮的事情。
