英語語法學(xué)習(xí)：英語中的語氣的種類
陳述語氣
表示動(dòng)作或狀態(tài)是客觀存在的、確定的或符合事實(shí)的，用于陳述句、疑問句和某些感嘆句中。如：Iraq is an Asian country. 伊拉克是亞洲國家。(肯定句)The US and British armies did not start the Second Gulf War until March 20,2003.美英聯(lián)軍直到2003年3月20日才發(fā)動(dòng)第二次海灣戰(zhàn)爭。(否定句)Who was it that they want to help? 他們想要幫忙的人到底是誰呀?(疑問句)How interesting my stay in China has been! 我在中國的日子過的真有趣!(感嘆句)

Please come over here. 請到這邊來。Would you be so kind as to lend me a hand? 請幫個(gè)忙好嗎?Watch your steps! 當(dāng)心!(走路)Never be late again! 再也不要遲到了。
虛擬語氣
