一般现在时的用法
一般现在时表示人、事、物现在的状况和特点或表示经常性、习惯性的动作,句中常有always、often、usually等时间状语。现在时还可用于表达格言、科学事实、客观真理和至今不变的客观事实。
注意:
主语是任何一个单数名词或者是第三人称单数,谓语动词要进行必要的变化。特别提一点:不可数名词也算作单数处理。
动词第三人称单数的变化规则及发音规律
动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同,请认真观察。
1、大多数动词在词尾加“S”,在清辅音后发音为[s],在浊辅音及元音后发音为[z]。
如:stop-stops [s] make-makes [s] read-reads [z] play-plays [z]
2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz]
如:fly-flies [z]; carry-carries [z] study-studies [z]; worry-worries
3、以“s, x, ch, sh”结尾的,在词尾加“e s”,发音为[iz]
如: teach-teaches [iz]; watch-watches [iz]
4、以“o”结尾的动词,加“es”,读[z]
如:go-goes [z] do-does [z]
