apple.3、完成1a，把单词和图片链接起来，并根据自己的情况，选出你平时最喜欢吃的食品。4、groupwork：除了1a中列举食品外，你还了解哪些，和你的伙伴谈一谈，编对话像这样：5、学习1b对话，谈论某人做某事的频率6、听录音，1c中的“问题”你如何回答？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 teacher.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 often。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 for; be good at; be good with; be good tobe good for...表示“对……有益（有好处）”;其反义为：be bad for...。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【训练案】一、单项选择。（ ）1、_____do you drink coffee? -----twice a day. a. how many b. how long c. how soon d. how often（ ）2、my teacher wants me _________ hard.　　a. study b. studying c. to study d. studies（ ）3、eating fruit and vegetables ____ our health.　a. is good to b. is good c. is good for d. is well for（ ）4、miss liu is very ________, because she exercises every day.　　a. health b. healthy c. unhealthy d. unhealth（ ）5、thank you for _______ me with my english.　　a. help b. to help c. helping d helps（ ）6、 _______ milk do you drink? 　　a. how many b. how much c. how often d. how soon二、用所给单词的适当形式填空。1.my mother_______(want)me_________(drink)more water every day.2.she says it’s good for my_________(healthy).3.thanks for________(help)me with my english.4.i can’t stand__________(get up)early in winter.三、根据汉语意思完成下列句子。1.谢谢来接受采访thanks for________ in ________the interview.2.做眼保健操对你的眼睛有好处doing eye exercises________ ________ ________your eyes.3.你妈妈每晚睡多少小时？________ ________ ________ ________your mom sleep every night?4.孩子需要许多睡眠。 children need________ ________ _________.5.我从不喜欢垃圾食品。 i_______ love_______ ________.6.我想让她买那条裙子。 i want_______ ________ _________that dress.四、根据句意和首字母补全单词1）my mother says it's good for my h________.2) lily e________ every morning to stay healthy.3) i usually watch tv at night, but s________ i go for a walk with my parents.4)i like to d______ coffee.五、根据短文内容填空what is junk food?junk food has lots of fat, salt and sugar. having too much of them is________ for people’s health. hamburgers, hot dogs, french fries, colas and ice creams are_________ junk food!why is junk food popular?junk food is _______in the world. first, it is cheap（请记得收藏本站-一路高升范文网，以获取更多新鲜内容） to make. second, it is_______ and easy for people to eat. third, most junk food has food additives(添加剂),so it looks good and it tastes_________.why is junk food bad?junk food is bad for ________.it makes people overweight and causes many healthy problems.how _________can you eat junk food ?it’s ok to have junk food_______ and then. if you are too heavy, you’d ____________ not eat it or try to eat less. if you are very healthy and live a regular(有规律的) life, you can eat it ________.我的收获：____________________________________________________________________我的疑惑：_____________________________________________________________________
