参考答案及详解I.1.were 2.had known;would have sent 3.were to/should rain;would be put
4.Had;seen;would have asked。如果条件从句的谓语动词是were或助动词had,should时,if可省略,把主语与were(had,should)的位置互换。
5.hadn’t talked 6.leave;hand。凡表示“决心,命令,建议,要求”的动词,后接宾语从句中的动词用“(should)+v.”这种虚拟形式。这类动词归纳为“一坚持(insist),二命令(order,com-mand),三建议(advise,suggest,propose),四要求(demand,desire,request,require)”。而表示这类意思的动词的相应名词,后接同位语从句时,也用虚拟形式。
7.is;wait。动词insist作“坚决要求”或“坚持要……(做)”解时,后接的宾语从句的动词用“(should)+v.”表示主语的一种愿望和意图。若作为“坚持认为”、“坚持说”或“力言”解时,则从句用陈述语气来表示一种存在的具体事实。类似用法的动词还有:suggest(作“建议”解,用虚拟;作“暗示、显示、使想起”解,用陈述)。
8.had;have arrived。“It is(high)time+定语从句”句型用来强调“该干什么事了”,有时还含有“为时已稍迟”之意,此定语从句的动词用虚拟过去式(或should+v.)。“It be...time(that)+定语从句”系主从复合句句型,用来叙述一件事实的情况,定语从句的动词用陈述语气。
9.were。在“would rather(that省略)……”句型中(意为“宁愿、巴不得”),从句的虚拟形式有:①与现在事实相反的愿望,动词用过去式(be用were)。②与过去事实相反的愿望,动词用had+过去分词。10.(should)be
11.(should)be rechecked 12.hadn’t made;have passed
