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 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 don`t 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 don`t 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. _______________________________________________ 13. We play basketball on Sundays.
_________________________________________________ 14. Tom likes listening to music
____________________________________________
肯定句改一般疑问句的方法————————三步法
1. 有be动词/情态动词：be动词/情态动词提到句首，其余照抄，(some改成any，my改成your）句末用问号。
2. 无be动词/情态动词，在句首加Do/Does/Did，其余照抄，(some改成any，my改成your）句末用问号。
3. 加Does、did 的句子注意，句子动词要变成原型。 例如： 陈述句: They are
in the park. He can play the guitar.. 一般疑问句: Are they in the park? Can he play the guitar? 陈述句: I like the ducks. He likes the dogs. 一般疑问句： Do you like the ducks? Does he like the dogs? 把下列句子变成一般疑问句
1. I am listening to music. __________________________ 2. Mike is a student. _______________________________________
3. Sarah can clean the classroom.________________________________________ 4. They are in the zoo. ________________________________________ 5.

一、绝大多数的可数名词的复数形式，是在该词末尾加上后辍-s。 读音变化：结尾是清辅音读[s]，结尾是浊辅音或元音读[z]。
例：friend→friends; cat→cats; style→styles; sport→sports; piece→pieces 二、凡是以s、z、x、ch、sh结尾的词，在该词末尾加上后辍-es构成复数。 读音变化：统一加读[iz]。
例：bus→buses; quiz→quizzes; fox→foxes; match→matches; flash→flashes
三、以辅音字母+y结尾的名词，将y改变为i，再加-es。
