英语语法学习：英语中的语气的种类
陈述语气
表示动作或状态是客观存在的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句中。如：Iraq is an Asian country. 伊拉克是亚洲国家。(肯定句)The US and British armies did not start the Second Gulf War until March 20,2003.美英联军直到2003年3月20日才发动第二次海湾战争。(否定句)Who was it that they want to help? 他们想要帮忙的人到底是谁呀?(疑问句)How interesting my stay in China has been! 我在中国的日子过的真有趣!(感叹句)
祈使语气
表示说话人对对方的请求、警告，建议或命令。如：
Please come over here. 请到这边来。Would you be so kind as to lend me a hand? 请帮个忙好吗?Watch your steps! 当心!(走路)Never be late again! 再也不要迟到了。
虚拟语气
虚拟语气表示说话人的主观愿望、猜疑、建议或与事实不符的假设等，而不表示客观存在的事实。虚拟语气是由句中的谓语从句的特殊形式表示出来的。如：
