2、Indicative Mood)，祈使语气(The Imperative Mood)和虚拟语气(The Subjunctive Mood)。陈述语气是用来陈述一个事实或提出一种看法。祈使语气则表示请求、命令、警告或劝告等。而虚拟语气则表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测。如：I saw Wang Ping yesterday.我昨天见到了王平。(陈述语气)Do come to the meeting next Monday.下周一一定要来开会。(祈使语气)If I were you，I would not do it like that.假如我是你的话，我就不会那样做。(
3、虚拟语气)(二)虚拟语气在if条件句中的用法1表示与现在事实相反的假设，其基本结构是：条件从句中谓语动词用过去式(be的过去式用were)，主句中用would/could/should/might动词原形。如：If everyone in the country knew first aid，many lives would be saved.如果每个国民都懂得急救的话，许多生命就会得以挽救。(含义是：并非人人懂得急救，所以很多生命得不到挽救。)If I were a boy，I would go alone.如果我是个男孩，我就独自去。(含义是：我不是男孩，故我没有单独去。)2表示与过去事实
4、相反的假设，其基本结构是：条件从句中的谓语动词用“had过去分词”，主句中则用“would/could/should/mighthave过去分词”。如：If we had known that she was to arrive yesterday，we could have met her at the station.如果我们知道她昨天到，就可以到车站去接她了。(事实是：我们不知道她昨天到，所以我们没能到车站接她。)If the hurricane had happened during the daytime，there would have been more deaths.如果飓风发
5、生在白天，死亡人数会更多。(事实是：飓风没发生在白天，死亡人数相对不多。)3表示与将来事实相反的假设，其基本结构是：条件从句中的谓语动词用过去式be的过去式一般用wereshould动词原形were to动词原形主句的谓语动词用：should/could/would/might动词原形。如：If it rained tomorrow，our plan would be put off.假如明天下雨，我们的计划就得推迟。If he should see me，he would say hello to me.假如他看见我，他会向我问好。(用“should动词原形”强调一种有偶然实现的可能性，其实
6、现性比“were to动词原形”大，比“过去式”小)If he were to come，what should we say to him?假如他来了，我们对他说什么呢？(用“were to动词原形”比较正式，多用于书面语中，表示实现的可能性很小。)综上所述，可列表如下：虚拟条件句中谓语动词的构成形式另外，需要注意在if条件句中，若含有should或were或had，可以省去if，把should/were/had提到主语之前，构成倒装句。如：Were I you，I would not go.If I were you，I would not go.如果我是你，我就不会去。(三)虚拟语气在动
7、词wish后的宾语从句中的用法1表示目前未能实现的愿望，从句的谓语动词用过去式。如：I wish I were young again.我希望自己仍然年轻。2表示过去未能实现的愿望，从句的谓语动词用过去完成时。如：I wish I hadnt told him the secret.我真希望我没告诉他这个秘密。(实际上已告诉了他)3表示将来的愿望有可能实现(但可能性较小)时，从句的谓语动词用would/might动词原形。如：I wish you would stay a little longer.我希望你能再待一会儿。归纳拓展 should在if条件句中只出现在与将来事实相反的情况，在主句
8、中只出现在主语是I和we时。,虚拟语气从句如果把if省略时只能把had，were和should提到主语之前，没有did这个词。,注意有时不出现if从句，但通过介词短语或连词可以体会出一个if从句来，这叫做含蓄条件句。介词有without，but for.，连词有but，otherwise。如：,Without electricity，our life would be quite different.,He went to the meeting yesterday，otherwise he would have missed the important news.新写作技法点拨如何写建议信建
