但可接what引导的名词性从句。
(3) A hinge joint is —— permits the forward and backward movement of a door.
(A) the
(B) what
(C) those
(D) whose (88.10)
B what = the thing that
(4) Essentially, a theory is an abstract. Symbolic representation of —— reality.
(A) what it is conceived
(B) that is conceived
(C) what is conceived to be
(D) that is being conceived of (89.5)
C what = the thing that (is conceived to be ) .答案(A)中的代词it是多余的,因为what本身即已包含了先行词(the thing ) 和关系代词(that) .答案(B)中的关系代词that引导的从句不可以置于介词的后面。

B what应改为that.此句已含有先行词food,不能再用关系代词what.
