II. 一般过去时的构成
谓语动词为be动词的一般过去时的构成同谓语动词为be动词的一般现在时构成一样,只需把am,is,are变为was, were
我们主要来学习谓语动词为实义动词的一般过去时的构成。
动词过去式的构成:
(1)规则动词过去式的构成有四条规则:
①一般在动词原形末尾直接加上-ed。如:look—looked。
②以不发音的字母e结尾的动词,去e再加—ed。如:live-lived。
③末尾只有一个辅音字母的重读闭音节,先双写这个辅音字母,再加—ed.如:stop-stopped。
④末尾是辅音字母+y结尾的动词,先变y为i,然后再加-ed。如:study—studied。
(2)不规则动词的过去式需特殊记忆。如:am(is)—was, are—were, go—went, take-took, have (has)—had等。
III. 一般过去时的几种句型
肯定句结构为:主语+动词的过去式+其它。如:
否定句结构为:主语+did not (didn’t)+动词原形+其它。
一般过去时的一般疑问句的构成:Did+主语+动词原形+其它 如:
1) —Did you go to Beijing last week -Yes, we did. (No, we didn’t。)
一般过去时的特殊疑问句的构成:疑问词+did+主语+动词原形+其它?如:
1) —What did you do last night? -I did my homework.
三、现在进行时( 定义:表示此时此刻正在进行的动作或事情。)
构成:现在进行时的构成是:主语+be+ v.ing〔现在分词〕形式
肯定句:主语+be(is/am/are)+现在分词
否定句:主语+be(is/am/are)+not+现在分词
一般疑问句:be(is/am/are)+主语+现在分词
特殊疑问句:特殊疑问词+相应be动词+主语+现在分词+Sth?
变化规则
直接+ ing (例:sleep+ing sleeping)
去掉不发音的e+ing(例:biting,leaving,making, coming, writing. )
注意:如果单词结尾的e发音,则不能去掉,也直接加ing. 例如:see —seeing/agree — agreeing 。
3. 以ie结尾变ie为y+ing (例:die—dying lie-lying)
4. 对于重读闭音节词,双写末尾字母再加ing。 例如:sitting, beginning, getting, putting, run - running,stop - stopping ,cut - cutting ,control - controlling
基本用法:
A.表示现在(指说话人说话时)正在发生的事情。例:We are waiting for you。
