Talk about the four basic ntence types: declarative, interrogative, imperative and exclamatory.
一、 陈述句(Declarative Sentence)是陈述一个事实或者说话人的看法。它包括肯定句（The Affirmative Sentence）和否定句（The Negative Sentence）两种。陈述句在书写时句末用句号，在朗读时用降调。
1.肯定句：基本结构为主+谓
He went to London to pass his holiday.
2.否定句：
1).全否定
用not, no, never, neither, none, nothing等否定。表示“完全不是，完全不”的意思。
Nothing is wrong with me.大叔电影
2).半否定句
在句子里用否定词hardly, scarcely, little, few, ldom, rarely等。
I hardly e anything in the room.=I can e little in the room.
“all/both/every/each/+谓语+not”表示概念为“有的是，有的不是”
All of them are not students.=Some of them are students, some are not.
二、疑问句（interrogative Sentence）用来提出问题，表示疑问的句子就叫疑问句。这类句子的形式比较多，中学阶段常见的有一般疑问句、特殊疑问句、选择疑问句和反意疑问句。
1.胰岛素泵的优缺点一般疑问句
一般疑问句是用来询问某人或某物是否属实，并且要用yes或no来回答的疑问句。这种疑问句朗读时要用声调。其语序一般要用倒装结构。如：
-Are you an engineer?
-Yes, I am或No, I am not.
2.特殊疑问句
以疑问代词（who, whom, who, what, which等）或疑问副词（when, where, why, how等）开头的疑问句就叫特殊疑问句。这种疑问句朗读时用降调。其句式结构分正常语序和倒装语序两种形式。如：
What has happened to her?
When did he fly to America?
3.选择疑问句
在句中提供的两个或多个答案中选择一个作回答的疑问句，就叫做选择疑问句。朗读时前面的一个或多个选择用升调，最后一个选择用降调。这种疑问句的句式结构有两种情况：即一般疑问句和特殊疑问句再加上供选择的两个或多个部分。但不管用哪种形式，都要按实际情况来回答。如：
——Do you enjoy playing football or volleyball? –I enjoy playing volleyball.
——Which floor do you live , on the 15th floor or on the 21st floor? –On the 21st floor.
4.反意疑问句
表示提问者对自己所陈述的事情有怀疑或是没有把握，需要别人加以证实的疑问句，就叫做反意疑问句。其句式结构由两部分组成，即陈述部分再加一个简略问句。如果陈述部分是肯定句，简略问句就用否定形式；反之，简略问句用肯定形式
。但不管用哪种形式，前后两部分中的人称、数、时态等都要保持一致，并且陈述部分中的主语不论是用什么词充当，简略问句中的主语一定是一个人称代词。对反意疑问句的回答，其肯定形式都用yes，否定回答用no。朗读时，陈述部分通常用降调，简略问句部分
用升、降调随情况而定。如：
——You spoke at the meeting yesterday, didn’t you?
——Yes, I did. 或No, I didn’t .
三、感叹句(imperative Sentence)含有表示情绪色彩的句子叫感叹句。感叹句的结构通常有三种形式：武平文博园1.what引导的感叹句，强调句中的名词；2.how引导的感叹句，强调句中的形容词或副词；3.由感情色彩的单词或词组构成的感叹句。
1)．What引导的感叹句。What +a /an + adj. + n.+主谓结构！（有时主谓结构可省略）。如：
What a hot day （it is）!
美女图片素材What good advice the teacher gave us!
What high buildings （they are）谋攻!
2)．How引导的感叹句。How + adj./adv.+主谓结构！如：
How interesting the book is!
How hard they are working!
四、祈使句(exclamatory Sentence)表示请求、命令、禁止、劝告或建议的句子叫祈使句。祈使句的主语往往省略。其常见的句式结构可归纳为四种基本形式：（1）肯定祈使句；（2）否定祈使句；（3）以Let’s开头的祈使句；（4）以助动词do开头的祈使句。
1．肯定祈使句。如：
女孩子学什么专业好
Stop talking! Come here in time!
2．否定祈使句，即以Don’t或Never开头的句子。如：
风娘Don’t talk in class. Never leave today’s work for tomorrow.
3．以Let’s 或let开头的句子。如：
Let’s go together. Let him go first.
4．以助动词do开头的祈使句，在句中起加强语气的作用，译成“一定，务必”。如：
Do come to e me if you have time.
