1.___ computers not been used,it would have taken them more time to solve the problem.a.If have b.Have c.If had d.Had2.It hasn't been decided whether the equipment ____ at once.a.should put into use b.must be put into usec.will e put into use d.be pu
第一题选d,是因为要与would对应,have与will对应.
第二题翻译过来是说“还没有决定这件装备是否应该立即被投入使用”其中应译出“应该(should)”排除b,equipment 是从句中的主语,物做主语用被动,排除ac.d选项完整的应该是should be put into use

两句都是典型的虚拟语气,第一题在虚拟语气中,if引导从句时,可以将引导词省略,条件是将可以提前的词提前,= if computers had not been...
第二题更为复杂:在表达命令建议请求等语气时, 从句用should加动词原形来表示,而should经常被省略。

1题。该题应用虚拟语气的过去完成时
2题。decide后跟虚拟语气,结构为should + 动词原形(should可省略)
