一般现在时用法讲解
教学内容
一般现在时
【定 义】
一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作。即描述我们日常生活中的衣食住行等活动。
【用 法】
(1) 在实际应用中，一般现在时常与以下时间状语联用：
always, usually, often, sometimes, every week (day, year, month, once a week, on Sundays ……
例句：He usually plays football on Sundays.
(2)没有时间状语，可以分以下四种类型：
A．be型
   这一类型由be动词+名词、形容词、副词、代词、数词或介词短语等一起构成谓语，表示主语的个性、特征或状态。如：
   ①I am a student.(主语+be动词+名词) ②They are hungry.（主语+be动词+形容词）
   ③He is out.(主语+be动词+副词) ④That pen is mine.(主语+be动词+代词)
   ⑤I am fifteen.(主语+be动词+数词) ⑥The bike is under the tree.(主语+be动词+介词短语)
B．do型
   do型由行为动词充当谓语，表示经常性或习惯性的动作，
其构成为“主语+动词原形或动词第三人称单数形式”。如：
   ①I know it.   ②He believes me.
C．there be型
   there be型句子表示“某地存在…”，其构成为“there be+主语+其他”，表示客观事实。用法遵循“就近原则”，即主语是单数或并列主语中的第一个主语是单数，则用there is；主语是复数或并列主语中的第一个主语是复数，则用there are。如：
   （1）There is an eraser on the teacher's desk.(主语an eraser是单数)
   （2）There is an orange，five apples and eight bananas in the bag.(并列主语中的第一个主语an orange是单数)
D．情态动词型
   情态动词型句子的构成为“主语+情态动词+动词原形”，情态动词和动词原形一起构成谓语，表示说话人对所叙述的动作或状态的看法。如：
   ①He can speak a little English.(can+speak) ②May I have a book, please?(may+have)
【练 习】

is 用于三人称单数主语she, he, it或单个的人和物之后，构成She/He/It is…句型。
are用于二人称you或复数主语we, they之后，构成You/We/They are…句型。
be为该动词的原形，用于情态动词can, may, must…之后或用于祈使句中。
