问题: 答案选什么？ 为什么?
--Who is it up to ______the camp fire?
--It's ______ who is on duty today .
A. to watch ; Tom rather than I
B. watch; rather than Tom
C. watching ; Tom rather than I
D. watched ; I rather than Tom
解答:
Who is it up to ______the camp fire?
还原：it is up to who to (do) the camp fire.选to watch.
It's ______ who is on duty today.强调句，被强调部分在选项中，选Tom rather than I。
原句可看成下列的省略：It's Tom who is on duty today rather than (it's) I (who am on duty today).省略后将rather than I前置，和Tom并列处理作为复合强调部分。
