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。playplays stopstops makemakes read-reads(2) 以为o,sh,ch,s,x结尾的动词+es.teachteaches watch-watches(3) 以辅音字母Y结尾的动词把Y变成i再+es。flyflies carrycarries studystudies worry-worries(4)以o结尾的动词，在词尾加es. go-goes dodoes不规则：Havehas 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, every week (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：Abe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： I am a student. (主语+be动词+名词) 我是一名学生。 They are hungry. （主语+be动词+形容词）他们肚子饿了。 He is out. (主语+be动词+副词) 他出去了。 That pen is mine. (主语+be动词+代词) 那支钢笔是我的。 I am fifteen. (主语+be动词+数词) 我十五岁。 The bike is under the tree. (主语+be动词+介词短语) 那辆自行车在树下。Bdo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： I know it. 我知道这。 He believes me. 他相信我。Cthere 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 teachers 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： He can speak a little English.(can+speak) 他会说一点儿英语。 May 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dont(you, I或者复数)或doesnt（第三人称单数）。e.g.I dont like English.His father doesnt 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。 e.g.1.
