一. 用法（注意主语与动词的变化） 1、表示经常发生、反复进行的动作。
特征词有：often, always, usually, sometimes, every day等。 （如果同学们看到句子中有这些词就说明是一般现在时）
如：I often go to school at 7:00.
He often goes to school at 7:00.(主语是第三人称单数时动词就要变化) 二、构成
1、（be动词的一般现在时形式，不同的人称和数分别为am, are, 和is。）
2、主语不是第三人称单数时（I，we, they , you, 表示复数），动词用原
如: We usually go to school at 7:00. They usually go to school at 7:00.
3. 主语是第三人称单数时(如：she, he, it, Amy, Mike…)，动词用第三人称单数形式，即：在动词原形之后加-s ，其构成与名词复数形式一样，（动词的意思没有变化）。
动词三单变化口决： 一般情况词尾“s”加； o, s, x, sh, ch结尾, “es”不能差；
（1）一般动词在词尾加- s。如：like--likes, play--plays, eat—eats
练习题： 用给出词的适当形式填空。 She (like) English very much.
Mike often (play) football after school. （2）以字母s、x、ch、sh或o结尾的动词加-es 。
如: pass—passes传递 fix--fixes 修理 teach--teaches 教
watch—watches 观看wash--washes 洗 brush---brushes go--goes 去 do—does 做
John often (watch) TV in the evening. (对比：I often watch TV in the evening.) What he (do) on the weekend? He often (do) his homework on the weekend.
（3）在辅音字母+y 结尾的动词，先变y为i，再加-es。 如: fly--flies 飞 study--studies 学习 try—tries 尝试
注意：在元音+y 时，y不变, 直接加-s。
如：say--says stay--stays play--plays 4、一般现在时的否定及疑问形式。
如：I am a student.(改为一般疑问句)-----Are you a student? He is a teacher.(改为否定句)---- He is not a teacher. (2) 否定式及疑问句都要由
如： They know English .(改变否定句)----They don`t know English. (改为一般疑问句)---- Do they know English?
He likes music. （改为疑定句）----He doesn`t like music. (改为一般疑问句) -----Does he like music? 注意：Does、doesn't来帮你，后面动词恢复原形要紧记!!
