摘要：虚拟语气用于名词性从句 (1)虚拟语气在宾语从句中的运用. ①“wish + 宾语从句表示不能实现的愿望.译为“要是--就好了等.表示现在不能实现的愿望.从句中的谓语动词用一般过去时,表示将来不能实现的愿望.从句中的谓语动词用“would/could + 动词原形 ,表示过去不能实现的愿望.从句中的谓语动词用“had + 过去分词或“could + have + 过去分词 .如: I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. ②在表示建议.要求.命令等的动词suggest.advise.propose.demand.require.insist request.command.order等后的宾语从句中.谓语动词用should + 动词原形或是动词原形.如: She suggested we leave here at once. The doctor ordered she should be operated. (2)虚拟语气在同位语从句和表语从句中的运用. 作表示建议.要求.命令等的名词advise.idea.order.demand.plan.proposal.suggestion.request等的表语从句和同位语从句.从句中的谓语动词用“ + 动词原形 .如: His suggestion that we go to Shanghai is wonderful. My idea is that they pay 100 dollars. (3)虚拟语气在主语从句中的运用. 在主语从句中.谓语动词的虚拟语气用“should + 动词原形的结构.表示惊奇.不相信.理应如此等.如: It is necessary(important, natural, strange, etc.)that we should clean the room every day. It was a pity (a shame, no wonder, etc.)that you should be so careless. It will be desired(suggested, decided, ordered, requested, proposed, etc.)that she should finish her homework this afternoon. 注意:这种从句表示的是事实.如果说人对这种事实表现出惊奇的情感.就可用虚拟语气.反之.如果不表示惊奇等情感.that从句也可用陈述句语气.如: It is pity that you can’t swim.
