小学英语语法讲解--现在进行时(3)
语法讲与练1现在进行时
一、概念
表示正在发生的事情或动作,也可表示当前一段时间内的活动或现阶段正在进行的动作。常和now,look,listen连用。
如:We are listening to music now. 我们现在正在听音乐。
Listen! He is playing the piano. 听!他正在弹钢琴。
二、句子结构
1.be + 动词现在分词(即:动词-ing形式),be + doing 是一个整体,不能分开。
如:1、Tom is reading books in his room. 2、中译英:我们正在这儿学习。
2.be 随着主语的变化而变化(口诀:我用am, 你用are, is用在他她它,所有复数全用are)
doing的变化规则根据现在分词的变化规律来定。
三、动词现在分词的构成规律
1.一般情况下,在动词原形后直接加-ing;
如:work→working do→ play→
2.以不发音字母e结尾的动词,先去掉e,再加-ing;
如:dance→dancing come→
3.在重读闭音节(即:辅音+元音+辅音)的动词中,要先双写末尾的辅音字母,再加-ing;
如:get→getting shop→ run→ swim→
4.以ie结尾的重读闭音节词,将ie改成y再加ing。
如:lie→lying die→
四、现在进行时的各种句式变化 1.否定句
方法:直接在be的后面加not。
如: They are running. →They are not running.
2.一般疑问句
方法:直接把be放在主语的前面,其余位置不变。 如:They are running. →Are they running?
Tom is reading books in his room. →
3.特殊疑问句
方法:如果就划线部分提问事情或动作时,用What…doing?
如:They are swimming in the sea now. →What are they doing in the sea now?
→
