7、再听录音，回答1d中的问题，
8.朗读1e的对话，进行采访问答
然后小组展示。（要求：1人扮演记者，1人扮演Bill, 1人扮演Tina
观察与思考：
一、将一个句子变为否定句的三个步骤：1、在要求变为否定句的句子中寻找be动词am、is、are、was、were，若有其中某个的话，在其后边加not即可（也可将其两个词缩写：is
not=isn’t；are not=aren’t；was not=wasn’t； were
not=weren’t）。2、若在要求变为否定句的句子中找不到am、is、are、was、were，就在其中寻找情态动词can、may、must、should、will、would、could、shall等，若有其中某个的话，就在其后加not即可（也可根据需要将其缩写：can
not=can’t, must not=mustn’t, will
not=won’t）。3、若在要求变为否定句的句子也找不到情态动词，就借助助动词do、does、did，第三人称单数借助does，不是第三人称单数借助do，一般过去时借助did，并在其后加not（分别可缩写成don’t、doesn’t、didn’t）后边的动词打回原形。
例1：He is a teacher.(变否定句)He is not a teacher. 或He isn’t a
例2：They can dance.（变否定句）They can not dance.或They can’t dance.
例3：Jim likes pets. (变否定句)Jim does not like pets.或Jim doesn’t like
pets.注意：例3中likes→like，即动词由第三人称单数形式打回为动词原形。
二、将一个句子变为一般疑问句也有三个步骤，且类似变否定句的规则。即：将找到的be动词或情态动词提到句首，末尾加问号，若没有be动词或情态动词，同样的方法借助do、does、did，并将其提到句首，动词打回原形，末尾加问号。注意：遇到some变any，并根据语境更改相应的人称和物主代词。请将例1、例2、例3变为一般疑问句：
例1_______________________.例2__________________________.例3______________________.
三、特殊疑问句的变法：通常对划线部分提问的过程就是变这个句子为特殊疑问句的过程。基本结构：特殊疑问词 +
一般疑问句原则上划什么就用什么特殊疑问词。例如：划时间就用when，划原因就用why，划方式就用how，划频率就用how
例4：She exercises twice a week.(对划线部分提问)
How often does she exercise?
特殊疑问词 一般疑问句
练习：Jim likes pets.(对划线部分提问)_______ ________ Jim like?
四、1、how many 后加＿＿＿＿＿＿ how much 后加________________
2、.My mother wants me to drink milk.
want to do sth. 意思是“想要做某事”；want sb. to do
sth.意思是“想要某人做某事”。如：
Do you want to go to the movies with
me？你想和我一起去看电影吗？
The teacher doesn't want us to eat
hamburgers.老师不想让我们吃汉堡包。
3、She says it’s good for my health.
（1）be good for...表示“对……有益（有好处）”;其反义为：be bad
for...。（这里for 是介词，后跟名词、代词或动名词）如：It's good for us to do more
reading. 多读书对我们有好处。
Reading in bed is bad for your
eyes.在床上读书对你的眼睛有害。
Exercise is good for your health 锻炼有益于健康
He is good for nothing 他这个人没什么用。
【辨析】 be good
be good for...表示“对……有益（有好处）”;其反义为：be bad
be good at…“擅长于。。。。。。”，相当于do well in…
be good with (sb.)=get along well with
sb.与(某人)相处得好
be good to（sb.）=be kind/friendly to
sb.“对。。。。。。好”
4.health 不可数名词, 健康（指人体或心理状况），健康状况。如： my health. .
Doing sports is good for your health.， 常见短语 be in good(bad,
poor) health意为健康，不健康 His father is in good health
【拓展】：healthy adj. 健康的。----反义词：unhealthy. He is a
healthy teenager.
I have a healthy lifestyle. 短语： keep/stay healthy 保持健康,be
healthy/look healthy看上去很健康；healthily adv.健康地eat healthily健康饮食
