2、的时态。2)虚拟与非虚拟：即一句与事实相反，用虚拟；另一句与事实一致，用实际时态。3)虚拟中的倒装：如if从句中含should,had,were等，可将其置于句首，且省略if。4)介短、副词代替if从句：如without,butfor,intheabsenceof(如果没有),or,otherwise等。2.表示建议、要求、劝告、命令类词+名从中的虚拟，从句动词:(should)do适用词群：advise,ask,demand,desire,insist,order,propose,recommend,reques
3、t,require,suggest,urge等及其它们的名词、形容词、过去分词等，后跟名从。注意：当insist为“坚持已发生或存在的事实”，suggest为“暗示、表明”时，要用陈述语气，即实际时态。3.wish等词+从句：从句时态向后退一格：即表示现在、将来用did/were/was;表示过去用haddone。适用词群：wish,asif/though,Ifonly(要……就好了),wouldrather,Itis(about/high)timethat等。二、对点集训（一）用括号中所给动词的适当形式填空 1.
