[求助]大全806中的should

806        The president of the block association tried to convince her neighbors they should join forces to prevent crime in the neighborhood rather than continuing to be victimized.

(A) they should join forces to prevent crime in the neighborhood rather than continuing to be victimized

(B) that they should join forces to prevent crime in the neighborhood rather than continue to be victimized

(C) about joining forces to prevent crime in the neighborhood instead of continuing to be victimized

(D) for the joining of forces to prevent crime in the neighborhood rather than continue to be victimized（B）

(E) to join forces to prevent crime in the neighborhood rather than continuing to be victimized

请问B中的should为什么不省去？这里不是虚拟语气吗？

好像convince不用虚拟语气吧？我记得通常是suggest, dictate, mandate, propose等会用到虚拟语气。

那究竟什么词后面接虚拟，什么不接呢？白勇说allow,rule,propose,suggest后不用，但张道真又说propose后用。困惑ing............请问有这方面的归纳吗？

allow一般不用that

rule that是不用虚拟的

sb propose/suggest that要虚拟

sth propose/suggest that 不虚拟

should 是不是可以随便加呢？

在GMAT中should 是“应该”的意思么？

有allow that...

但不是"允许.."的意思,而表示"承认..."的意思,也不用虚拟.

convince that应该不用虚拟.如(摘至译典通):

I was convinced that he knew the truth.我确信他知道事实.
