有读者问： 有这样一道选择题：
(1)We haven't found a large room in which_________all these tools.
A. put B. to put C. putting D. for putting
答案是A，可我们老师说应选B，到底哪一个对呢？
你的老师是对的。 “in which+带 to 的不定式”结构是常见英语，再如：
(2)A notebook is a book in which to write notes.
(3)I had only a few minutes in which to enjoy the flower show.
顺便提一下，“which+带 to 的不定式”之前除可用介词 in 外，还可用其他介词如 against, by, from, on, with 等，实例如：
(4)The seats have no back against which to lean .
(5)This is the best means by which to gain the end.
(6)We had to look for something from which to make a fire.
(7)It's a board on which to cut vegetables.
(8)I must buy a hammer with which to nail down the box.
