19、like that book.我喜欢那本书。（陈述一个事实） I really agree.我确实同意。（陈述一个观点） 否定陈述句I did not buy the TV.我没有买那个电视。（陈述一个事实）（2）主语+连系动词+表语结构 肯定陈述名The film is boring . 这部电影没意思。（陈述观点） 否定陈述句Smoking is not good for your health.抽烟对你的健康没有好处。（陈述一个事实）3、 陈述句的否定结构：陈述句的否定式主要用两种结构来表达：（1）句子的谓语动词为be , have 或者谓语动词有助动词、情态动词时，其否定结构为：主语+
20、谓语动词/助动词/情态动词 + not + 其他成分 I am not a teacher. 我不是老师。We have not (havent) any books on animals. 我们没有任何有关动物方面的书。 The children are not (arent) playing in the playground. 孩子们没在操场上玩。 He will not (wont) come. 他不会来。We must not (mustnt) forget the past. 我们不能忘记过去。 It could not (couldnt) be lost. 它不可能丢的。（2）
21、当句子的谓语动词是do (即行为动词)，而且没有助动词或情态动词时，其否定结构为：主语+do (does,did) + not + 动词原形 + 其他成分You do not (dont) come here every day . 你没有每天都来这里。 He does not (doesnt) teach this class . 他不教这个班。They did not(didnt) watch TV last night . 昨晚他们没看电视。注意：陈述句的语调一般用降调。但在表示疑问的语气时，用升调，在书面上要用问号来表示。You really want to go to Hong Ko
22、ng ? 你真的想去香港吗？这句话表示的是一种疑问，只不过是通过陈述的语序和疑问的语气来表达的二 疑问句 疑问句是用来提出疑问的句子，句末用问号“？”。常考的疑问句有四类，即：一般疑问句、特殊疑问句、选择疑问句、反意疑问句。第一节 一般疑问句一般疑问句通常需要用yes 或no 来回答，所以又叫做“是非疑问句”。在读这种句子时要用升调。一般疑问句主要有以下几种类型： 1、“be + 主语 + 表语”结构 Are you sleepy ? 你困了吗？ Yes, I am . 是的，我困了。 3、“情态动词 + 主语言+ 行为动词（或be）”结构 May/Can I use the telephon
23、e? 我能用这部电话吗？ Yes, you can. 是的，可以。 5、“助动词（do, does, did）+ 主语 + 行为动词”结构 Do you like swimming in summer? 你喜欢夏天游泳吗？ No, I dont . 不，我不喜欢。难点提示回答否定性一般疑问句时，要在Yes 后面用肯定结构，表示肯定；在No 后面用否定结构，表示否定。注意在说法上正好与汉语习惯相反。诀窍是在回答的时候，只要把它当成没有加否定形式的普通一般疑问句看待就可以了。注意下面例句的回答和它的意思。Is he not your elder brother? 他不是你的哥哥吗？ Yes, he
24、 is . 不，他是（我的哥哥）。No, he is not. 是的，他不是（我的哥哥）。 Isnt she very clever? 她难道不是很聪明吗？ Yes, she is. 不，她很聪明。 No, she is not . 是，她不聪明。第二节 特殊疑问句一、特殊疑问句是用来提出来特定问题的疑问句，要求听到问题的人针对特定情况来做具体的回答，不能像一般疑问句一样简单地用Yes 或No 来回答，特殊疑问句要用降调来读。 二、特殊疑问句的结构：特殊疑问词 + 一般疑问句Who do English homework in the evening?谁晚上做英语家庭作业？ What do y
25、ou do in the evening?你晚上做什么？What homework do you do in the evening?你晚上做什么家庭作业？When do you do English homework?你什么时候做英语家庭作业？三、注意：对人提问时who“谁”对所属（谁的）提问用whose“谁的” 对哪一个提问用which“哪一个”对时间提问用when“什么时候”或what time“几点” 对物体提问用what“什么” 对地点提问用where“哪里” 对原因提问用why“为什么” 对方式提问用how“怎么样” 对数量提问用how many“多少”（用于可数名词复数）或how
26、 much“多少”（用于不可数名词）四、难点提示1、 以why开头的特殊疑问句否定形式常用于表示建议、请求等。 Why dont you have a try? 你为什么不试试呢？2、 特殊疑问句常用到一些缩略形式，在平时学习中要注意习惯这些用法。I dont want to go there. How about you? 我不想去那儿，你呢？ But what else? 可是还有什么呢？把下列句子变成否定句：1. I am listening to music. _ 2. Mike is a student. _3Sarah can clean the classroom. _ 4. They are in the zoo. _ 5. There are some flowers in the vase._6. This is my sister. _ 7. We are sweeping the floor._8. We need some masks. _9. They like making the puppet. _ 10. Su Hai and Su Yang live in a new house._11. I put a book on my head._ 12. They sing “In the classroom” together._
