2.构成:主语+动词原形+宾语一般现在时用行为动词的原形，但第三人称单数作主语时，动词要用第三人称单数形式。
e.g．We like reading books.He likes reading books.3.动词第三人称单数形式的构成：(1)一般的动词词尾+S。
play—plays stop—stops make—makes read--reads(2)以为o,sh,ch,s,x结尾的动词+es.teach—teaches watch--watches(3)以辅音字母Y结尾的动词把Y变成i再+es。
fly—flies carry—carries study—studies worry--worries(4)以o结尾的动词，在词尾加es.go---goes do—does不规则：Have—has are--is【No. 2】一般现在时的应用(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, everyweek (day, year, month…), once a week, on Sundays ……例句：He usually plays football on Sundays.他经常在星期日踢足球。
(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) 我是一名学生。
②They are hungry. （主语+be动词+形容词）他们肚子饿了。
③He is out. (主语+be动词+副词) 他出去了。
④That pen is mine. (主语+be动词+代词) 那支钢笔是我的。
⑤I am fifteen. (主语+be动词+数词) 我十五岁。
⑥The bike is under the tree. (主语+be动词+介词短语) 那辆自行车在树下。
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. 我知道这。
②He believes me. 他相信我。
C．there be型there be型句子表示“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) 讲桌上有一块橡皮擦。
（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)袋子里有一个橙子，五个苹果和八个香蕉。
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) 他会说一点儿英语。
②May I have a book, please?(may+have) 请问我能看一看吗？【No. 3】一般现在时的变化1.否定形式：首先找句子中有没有be动词（is, am或者are）或情态动词（can），如果有，只要在be动词或情态动词后面加上not。
e.g.He is not a teacher.She can not speak English.如果句子中没有be动词（is, am或者are）或情态动词（can）那么根据主语在后面加入don’t(you, I或者复数)或doesn’t（第三人称单数）。
e.g.I don’t like English.His father doesn’t exercise every day.2.一般疑问句：首先找句子中有没有be动词（is, am或者are）或情态动词（can），如果有，只要将be动词或情态动词提前，放到主语前面。
注意：句中第一人称和第二人称要互换。
e.g.1.I am an English teacher.2. He is crying under the tree.3. My birthday is on the twentieth of November.4. Mrs. Li and Kitty are in a big shop.5. Kitty is wearing her new uniform.如果句子中没有be动词（is, am或者are）或情态动词（can）那么根据主语判断在句首加入do(you, I或者复数)或does（第三人称单数）,当谓语动词是三单形式时要还原。
注意：句中第一人称和第二人称也要互换。
e.g.1. She wants to have a model car.2. I go to school on foot.3. Her father likes to read English.4. I do my homework after school特殊疑问句：首先分析划线部分的意思，确定用哪个疑问词（what, where, who, when, which, whose, how, how many, how much, what shape, what colour, what … doing, where … going, what … do）, 然后找句子中有没有be动词（is, am或者are）或情态动词（can），如果有，只要将be动词或情态动词放到主语前面（疑问词的后面）。
如果句子中没有be动词（is, am或者are）或情态动词（can）那么根据主语判断加入do(you, I 或者复数)或does（第三人称单数）。
注意：句中第一人称和第二人称也要互换。
