由于,动词的时态设计内容较多,我们这讲只讲一般现在时。
一般现在时
作用
一、表示一般性或经常发生的动作或状态
二、表示习惯性动作和状态或普遍的现象或常识
三、表示客观事实、客观规律和客观真理。在宾语从句中,即使主句的谓语动词用了过去时,只要从句表示的是客观真理,从句的谓语动词也要用一般现在时。
四、祈使句
一般现在时由动词原形表示,(除第三人称后动词要加s),系动词be和have有特殊的形式。
第三人称单数
在一般现在时中,如果主语是第三人称单数,谓语要有相应的变化。
一、一般情况加s,例如:looks, listens, visits
二、以ch, sh, s, x或o结尾的词,加-es,例如:teaches, washes, guesses, goes, does
三、辅音字母+y结尾,变y为i加-es,例如:carry-carries, study-studies
读音情况如下:
1、在[p], [t], [k], [f]清辅音后,读[s],例如:hopes, invites4, asks
2、在[z], [s], [?], [t?], [d?]后,读[iz],例如:teaches, wishes, fixes5
3、在浊辅音和元音及其它情况下, 读[z],例如:plans, tries, sends
