The results for watching TV are interesting. Thank you for helping me. 8. 活跃的，积极的 adj. 9. 健康 n. 10. 习惯 n. 11. 至于；关于 12. 看电影 逛街 滑板 上网 踢足球， 打篮球 看电视,active,health-healthy (形容词adj.)-unhealthy(反义词),habit,as for sth as for 常用于句首作状语，其后跟名词代词或动词的“-ing”形式 Eg. As for him, I want to see him here. As for the story, youd better not believe it.,go to movies / watch a movie,go shopping,go skateboarding,surf the Internet,play football (basketball),watch TV,13.表频率的词汇和短语： sometimes, always, often, usually, seldom, hardly ever, never； once a day, twice a month, three times a year, every two weeks. Eg. On weekends I always surf the Internet. I usually watch TV. I often sleep late. I sometimes listen to music. I hardly ever play computer games. I never play football. 14. 努力 尝试 try “ try to do sth”, 尽力 努力做某事，不包含是否成功的意思; “ try doing sth” 试着去做 Eg. I try to eat a lot of vegetables to keep healthy. Youd better try doing the experiment in another way. 15. 非常地，相当地 pretty 这里的“pretty”相当于“very” My eating habits are pretty good.,重要句型及语法,How often do you exercise? How often +助动词do(does/did)+主语+do sth, 疑问词how often是用来问频率，意思为“多经常，多久（一次）”，在这里助动词是起帮助构成疑问句的作用； Every day / Once a week / Twice a month / Three or four times a month等这些频度短语都是用来回答以上问句时经常用到的，相反在句中对这类词进行划线提问时，用“how often ”句型毋庸置疑。 Examples: does your mother go shopping?你妈妈多久购一次物？ Twice a week. Most students exercise three times a week. (就划线部分提问) How often do most students exercise? 区别 how often 与 how many times How often 用来提问每个动作间隔多久发生一次，即询问动作发生的频率。通常对一些表示频率的副词发生提问，也可以对频率短语进行提问； How many times “多少次”，是用来提问做某事的次数的，往往就once,twice, three times 等词语进行提问。,How often,典型例题 1. Li Ming does his homework every day. (就划线部分提问) How often does Li Ming do his homework? 解析：every day 属于频度短语，就它提问时用how often; 2. The old man went to the zoo three times this year. (就划线部分提问) How many times did the old man go to the zoo this year? 解析：这里就次数提问用 how many times. What do you usually do on weekends? 第一个do 为助动词，在这起帮助构成疑问句作用； 第二个do 为实义动词，意思是“做，干” Eg. What do your parents usually do on Sundays? They usually bring me to see a film.,一、单项选择题： 1. There are 50 students in our class. 75% students like going hiking. What does “75%” mean? A.

You shouldnt be so careless. should与 ought to表示“应该时，二者可通用，但 ought后面一定要接带to的不定式。语气也比 should强。 Eg. I should study hard.= I ought to study hard. You ought to (should) read the rules carefully before you start playing the game. had better表示“最好” had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。 had better （not）+ do sth Eg. It is pretty cold. Youd better put on my coat. Shed better not play with the dog.,一、单项选择题 1. _ I have a headache. A. Whats the matter, Judy? B. Where are you, Judy? C. Who are you? D. What are you doing, Judy? 2.

When are you going? What are you doing there? Who are you going with? How long are you staying?,重要知识点,1. be+ doing也可表示将来 严格来说，be going, be coming, be becoming都可以，不过在口语上， 几乎什么动词都可以表将来时态，不过是在非常近的将来，偶尔表较远将 来：When I grow up, Im joining the army. 但是在书面上，将来时态 我们建议用 will/shall+v.原形 Eg.：He will come back net week. 2. go+doing的用法 这是一个固定句型，表示“去做” He is going camping with his parents. 他要与父母一起去野营。 此类结构除go shopping“去买东西”等少数用法外，大多与体育或娱乐有关。 Eg.: go dancing / skating / climbing / hiking / hunting / walking / sightseeing etc. She is _ with her mother this afternoon. A. going to shop B. go to shop C. going shopping D. go shopping 解析：按语法讲，好像go to shop也对，同学们往往也会选A；其实这里涉及词的习惯性用法，go shopping是一个固定短语，选C。 3. Something 某物某事,something, anything, nothing等是不定指代词，当形容词修饰不定指代词时，形容词应置于其后，汉语翻译时通常前置。如： something different 不同的事情 Do you have anything important to tell me?你有什么重要的事情要告诉我吗？ He heard something interesting outside today. 今天他在外面听到了一些有趣事。 Eg. Is there _ in todays newspaper? A. something new B. anything new C. new something D. new anything 解析：因为形容词要置于不定代词后，排除C 又因为这是个一般疑问句，不能用something，得将其替换为anything，选“B”。 4. 区别how long 与when how long 意思是“多久，多长”，这个疑问词组是用来询问某个动作或状态 持续了多久，并且与之连用的动词应该是延续性动词，回答用for+表时间段的词组。 When意思是“什么时候，何时”，引导的是特殊疑问句，when可指比较泛的时间，也可指具体的时刻。 Eg. _ did they stay there? For two days. _ are you coming to see me? Tomorrow.,Practice,一、单项选择题 1. _ are you staying there? Just for two days. A. How often B. when C. How long D. How many 2. Im going to Tibet next Monday. _ A. I know. B. That sounds exciting. C. Im sorry to hear that. D. Thank you. 3. When are you going there? I am going there _ May 12th. A. in B. on C. at D. for 4. How about _ with us to the Great Wall.

A. hiking B. on hike C. to hike D. on hiking,二、短文填空，每个单词首个字母已给出。 A: Hey, Lily. What are you doing for vacation? B: Im v_ my uncle in london. A: When are you l_ for London? B: Im leaving the first week in October. A: Who are you going w_? B: Im going there with my parents. A: What are you d_ there? B: W_ are going s_, visiting museums and going to the beach.

B: Thanks a lot.,Visiting, leaving, with, doing, We, Sightseeing, weather, sunny, rains, have,walk,Unit4 How do you get to school?,介词in ，on和by都可以与表示交通工具的名词搭配，表示交通方式，但其用 法各不相同： 1用“by交通工具名词”表示交通方式。此时交通工具的名词只能用单数，不能用复数，也不能被冠词或物主代词等限定。如：by bike（骑自行车），by bus（乘公共汽车），by car（乘出租车），by train（乘火车），by ship(乘轮船)，by plane (乘飞机)等。 My parents often go to work by bus. 2. 用“by交通路线的位置”来表示交通方式。如：by land（从陆路），by water (从水路)，by sea (从海路), by air (乘飞机)等，如： We are going to England by air. 3. 用“in(on)交通工具名词”。此时交通工具名词前必须有冠词、名词所有格形式或形容词性物主代词等限定词修饰。In多用于封闭式交通，on多用于开放式交通，其用法与“by+交通工具民副词”相似. He often goes to school on a/his bike. We go there in a car. 4用“take a（the）交通工具名词”表示交通方式。如：take a bus（乘公共汽车），take a train（乘火车），take a ship（乘轮船），take a plane（乘飞机）；但“骑自行车”要用 ride a bike来表示。,交通方式表达,Will you take a bus to go there? 5表示“步行去某地”，可用下列两种句式： （1）go to 某地 on foot。如： She goes to work on foot她步行去上班。 注意：on foot不可说成on feet，on a the my foot，by foot等。 （2）walk to 某地。如： He walks to school every day .He goes to school on foot every day 他每天步行去上学。 注意： walk不可与on foot连用。 walk to后接地点副词 here，there，home时，介词to要省去。如: I usually walk home. 重要句型 1. How do you get to ? - I get there by car. 2. How long does it take? - It takes (sb) +多长时间+to do sth. 3. How far is it from to ? - It is 10 miles.,语法：特殊疑问句 英语中特殊疑问句构成：特殊疑问词+一般疑问句 询问的内容不同, 使用的疑问词也不同。我们学过的疑问词有what（询问事 物）, how (询问方式),how much（询问价格）, what time （询问时间， 尤其是点钟）, what kind of（询问种类）, why（询问原因），who（询问 人）, where（询问地点） 等等。 What do you usually do on weekends? I usually go shopping. Where are you going for vacation？ We are going to the Great Wall. What kind of movies do you like? 你喜欢哪一类型的电影？ I like action movies. 我喜欢动作片。 How do you get to school? (I get there) on foot. 知识要点 1. Leave for 动身去某地 “leave+地点名词”表示离开某地。When did you leave Beijing?,“leave for + 地点名词”表示“去某地” He is leaving for London next Sunday “leave A for B”表示“离开A去B地” They wont leave Beijing for Shanghai. 2. 区别A number of与the number of a number of 意为“许多的，大量的”，后可跟可数名词复数或不可数名词。当其后跟可数名词复数作主语时，谓语动词用复数；接不可数名词作主语时，谓语动词用单数。 A small number of students take the subway to school. the number of 意为“的数量”，其后接可数名词复数作主语，但谓语动词用单数。 The number of students in Class one is 50. 练习 一、句型转换： 1.
