The headmaster wanted the new classroom building___as soon as pos-sible.
  A.to put up               B.to be put up
  C.to have been put up      D.being put up

试题答案

选B。want 一词表示“打算，想要”，通常构成want to do与want sb. /sth. to do两种形式，因为building与put up之间逻辑上是被动关系，故want复合宾语中的不定式使用了被动式。该句的含义是“校长打算让这座新教学楼尽快建成”。
