行为动词的一般现在时(3)
当主语是第三人称单数，表示经常性、习惯性的行为时，我们这样表达：She speaks English.He lives far away frm schl.
如果表示不常做某事，该怎样表达呢？
她不说英语。他住地离学校不远。
She desn’t speak English.
He desn’t live far away frm schl.
主语是第三人称单数的行为动词的一般现在时否定形式是在行为动词前加desn’t (des nt ),这时要注意把谓语动词还原为动词原形。试比较肯定与否定句中行为动词形式的变化：肯定：He gets up very early. 他起床很早 。否定：He desn’t get up very early. 他起床不很早。
如果要问别人是否经常做某事，我们要采用下面的表达方式：—Des the panda eat meat?熊猫吃肉吗？—N, it desn’t. 不，它不吃。—Des it eat bamb? 它吃竹子吗？—Yes, it des. 是的，吃。
从以上例子可以看出，行为动词的第三人称单数一般现在时疑问形式是在句首加助动词des,而加des之后，后面的谓语动词像否定句一样也要用原形。试比较:肯定：He gets up very early. 他起床很早。疑问：Des he get up very early? 他起床很早吗？
肯定句：主语+动词的第三人称单数形式否定句：主语+desn’t +动词原形疑问句：Des+ 主语+ 动词原形？ Yes,主语+des. N, 主语+ desn’t.
现在我们把行为动词第三人称单数的各种句式总结如下：
