. n( K0 e4 P: J; L R* ], l7 o! {& Q( ^3 j3 O9 R$ u
这里的show属于朗文词典中的这条用法:" {, N, _* g- u. U: k3 s
be shown to be/do something
4 V- P* V# g- z% G$ U) V: V6 j The campaign has been shown to be a waste of money.
0 U- k) P5 f t The new treatment has been shown to reduce the number of deaths.
/ n4 {9 L4 q9 x. u, t5 u6 C+ L/ e6 }8 I/ w
而这里后接的不定式可以等价于从句,但从句中的谓语却要使用相应的时态或情态动词,如:/ K8 Z; N3 ~' `: Q: v
It has been shown that the campaign IS a waste of money.4 R5 K" R/ y/ F: Q r
It has been shown that the new treatment CAN reduce the number of deaths.
% U3 T' _) P- ]! X0 T5 `& F3 g( w/ o& J" O! D
回到原句中,我们用从句表达可以是(注意以下不同时态所表达的时间含义不同):: Y% E- M+ D/ r0 @1 W5 J
It was shown that teachers had utilzied the ideas, but eventually they reverted to previous practices.4 _' W! ]- ]( x& V; p# s! U: H

但却不说" r8 M |/ o! \' _
It was shown that teachers utilized the ideas, but eventually they reverted to previous practices. x5 z* F* |0 f% T( L
( M, X2 f& c; X所以原句9 U8 g: L+ V j0 P$ _. {) \4 ~
Teachers were shown to be utilizing/to have utilized 都是说得通的,却不能使用to utilize: s- J1 f- k' A' i2 _- I* I
