ive Mood)用来陈述一个事实，或提出一个看法，有肯定，否定，疑问或感叹等形式。 People get AIDS after having been infected with HIV. I have enough money ,I’ll go to Singapore next year. How should we help the people who are in trouble? • What a brave girl! (2)祈使语气（ The Imperative Mood）用来表示请求，邀请，命令，警告或劝告等。 • Let me do it. • Please keep quiet in the reading room. (3虚拟语气 (The Subjunctive Mood)表示说话人所说的不是事实，而是一种假设，愿望，怀疑或推测。 虚拟语气主要用于条件从句，让步从句和名词性从句。 使用虚拟语气的条件状语从句称为虚拟条件句，即非真实条件句。 表示的内容是一种“假设”，不是真实情况。 其结构形成是用从句谓语的时态结构和主句谓语时态结构来表现，也就是说句子中使用了与真实条件句子不同的非正常的谓语时态结构，常见形式如下： （ 1）表示与现在事实相反的假设情况，虚拟条件从句的谓语用过去时，系动词 be一律用 were，主句的谓语用过去将来时。 如： If we left now, we should arrive in time. If I were you, I would refuse the money. Even if he had the money, he wouldn’t buy it. (2)表示与过去事实相反的假设情况，虚拟条件从句的谓语用过去完成时，主句的谓语用过去将来完成时。 如： We would have dropped by if we had had time. If she had told him about the danger, he would not have。阅读剩余 0%
