二、重点句子：

1.How often do you exercise?你（你们）多久锻炼一次身体？

解析：How often +?助动词do(does或did) +?主语+ do sth.

疑问词how often是问频率(多久一次),（在这里助动词do(does或did)

是起帮助构成疑问的作用）与一般现在时或一般过去时连用，回答一般是用表

示频率的副词，如：once, twice, three times…, sometimes, often, quite, often, never, every day, once a week , twice a month , three times a month , three or four times a month等。

Eg1)——How often do you go to the factory

——Twice a week.你们多久到工厂去一次？每星期两次。

Eg2)——How often does he go shopping

——He goes shopping once a month.

2.——“What do you usually doonweekends”

——“ I usually play soccer.”“周末你通常做什么？”“我通常踢足球。”

解析：第一个do为助动词,

在这起帮助构成疑问的作用；而第二个do则是实义动词。

Eg1)What do you usually do on weekends I often go to the movies.

Eg2)What does she usually do on weekends She sometimes go hiking. 3.——“What’s your favorite program?”

——“It’s Animal World.”“你最喜欢什么节目？”“动物世界。”

4.As forhomework , most students do homework every day .

解析：as for...意思是“至于；关于”，常用于句首作状语，其后跟名词、代词或动词的-ing形式（即动名词）。

如：As for him，I never want to see him here.

至于他，我永远不希望在这里见到。

As for the story，you'd better not believe it.

关于那故事，你最好不要相信。

As for myself, I don’t want to go now. 至于我自己，我现在不想去。

As for the man, I know nothing about him. 至于那个人，我什么都不知道。

5. Mom wants me to get up at 6:00 and play ping-pong with her .

解析：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：

Eg1)Do you want to go to the movies with me你想和我一起去看电影吗

Eg2)The teacher doesn't want us to eat hamburgers.老师不想让我们吃汉堡包。

注意：有很多动词后面用这种结构做动词的复合宾语，如：

ask sb. to do sth.叫某人做某事

tell sb. to do sth.告诉某人去做某事

help sb. (to) do sth.帮助某人做某事

6. She says it’s good for my health.

解析：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：

Eg1)It's good for us to do more reading.多读书对我们有好处。

Eg2)Reading in bed is bad for your eyes.在床上读书对你的眼睛有害。

7. How many hours do you sleep every night?

8. I exercise every day , usually when Icome home from school.

eg)You’d better try doing the experiment in another way.你最好试试用另一种方法做这个试验。

11. My healthy lifestyle helps me?get good grades.

解析：help sb.(to) do sth.帮助某人做某事

12. Good food and exercise help me to study better.

解析：这里better是well的比较级，而不是good的比较级

13.Is her lifestyle the same as yours or different?

解析：be the same as … / be different from …

14. What sports do you play

16. You must try to eat less meat .

解析：try to do sth.表示“尽力做某事” ,不包含是否成功的意思,less是little的比较级

17. That sounds interesting.

解析：这是“主语+系动词+表语”结构的简单句。

sound（听起来），look（看起来），smell（闻起来），taste（尝起来），feel（觉得），seem（好象）,grow（变得）,get（变得）等词在英语中可用作系动词，后跟形容词作表语。如：

Eg1)It tastes good.这味道好。

Eg2)The music sounds very sweet.这音乐听起来很入耳。

Eg3)The smoke grew heavier and heavier.烟雾变得越来越浓了。

18. I think I’m kind of unhealthy.我想我有点不健康。

20.although=though虽然<不能与but连用>?

与之类似的情况：有because就不能再用so.

21.She says it’s good for my health.她说它对我的健康有好处。

解析：be good for对…有益；其反义词组：be bad for对…有害

如：Eating vegetables is good for your health.吃蔬菜对你的健康有益。辨析：be good for ,be good at ,be good with

be good for“对…有益”；

be good at“擅长于”；

be good with“和…相处的好”；

如：I’m good at playing football.

Are you good at children?

22.How come怎么回事

解析：表示某件事很奇怪，有点想不通。可单独使用，也可引导一个问句，相当于疑问词why.但how come开头的特殊疑问句使用的仍是陈述语序。

如：How come you didn’t tell me about it?

=Why didn’t you tell me about it你怎么不早点告诉我这件事

23.well,how about Tuesday哦，那星期二怎么样啊

解析：How about…=What about …，“…怎么样”，用来向对方征求意见。如：It’s very sunny today ,how/what about playing tennis?

24.Twenty percent don’t exercise at all.20%的学生根本不锻炼。

解析：“not…at all”“一点也不；根本不”

如：He didn’t do his homework at all yesterday.昨天他根本没有做作业。

拓展：not at all “不客气”=you are welcome.

如：---Thank you very much.

---Not at all xK b1. Co m

三、词语辨析

1.注意sometimes与几个形似的词的区别。

（1） sometime是副词，意为“在某个时候”，“某时”

例：Will you come again sometime next week?

（2） some time是名词词组，意为“一段时间”，做时间状语用

例：I will stay here for some time.我将在这呆一段时间。

（3）some times是名词词组，意为“几次，几倍”

例：I met him some times in the street last month.上个月我在街上遇到他好几次了。

（4）sometimes?是频度副词，意为“有时”=at times

例：He sometimes goes skateboarding on weekends.他有时周末去滑滑板。

2.time意为“时间”时，为不可数名词。

意为“次数，倍数”时，为可数名词，

例1：What time is it?

例2：I go to the movies three times a week.

注意：1）“次数”的表达方法：

一次once；两次twice；三次或三次以上用基数词加上times：three times、five times、one hundred times.

2）表示“……几次”的表达方法是：

once a day/ a week/ a month/ a year?

twice a day/ a week/ a month/ a year

3.same与different

解析：1）same指“相同的”，前面通常要有一个定冠词the，但是如果same 前面已经有this，those等词，不能再与the连用了。

例：We are in the same class.我们在同一个班级。

结构：the same as 与......一样如：

例：His mark is the same as mine.他的分数和我的分数一样。

2）different译为“不同的”，其后的可数名词应为复数形式。

例：We are in different classes. 我们在不同的班级。

结构：be different from 与......不同

例：This sweater is different from that one.这件毛衣与那一件不同。different的名词形式为difference, 复数形式为differences。

4.hard / hardly

1）hard: hard既可作形容词，也可作副词。

adj.辛苦的，困难的

adv.努力，使劲地

例1：He had a hard (adj.)time in the past.

例2：It's a hard (adj.) question. (=difficult)这是一个难的问题。

例3：The boy studies very hard (adv.). 那男孩学习非常努力

例4：He workshard.他努力工作。

结构：It's hard for sb to do sth 做某事对某人来说是难的。如：

例：It's hard for him to finish the work. 完成那项工作对他来说很难。注意区分：hard work 困难的工作

work hard 努力工作

2）hardly: hardly是频度副词，表示否定的意思。（=almost not）通常用在形容词、副词和动词之前。

hardly: adv.几乎不，简直不

例1）I can hardly see it.我几乎看不到它。

例2）Hehardlyworks.他几乎不工作。

反意疑问句：Ithardlyrains here,doesit

5.how often / how long / how soon / how far

1）how often:

“隔多久一次”，指动作的频率，答语常用often, never, twice a week等表示频率的副词或短语。（用于一般现在时或一般过去时）

例1）How often do you go to the movies?

例2）Once a week. / I never go to the movies.

2）how long: 1)“（延续）多长时间”，答语常用for＋时间段或since＋时间点。（用于各种时态）；

2)询问物体的长度。

例1）How long is the Yellow River?

例2）How long have you learned English

例3）I have learned it?for 5 years.

例4）I have learned it?since 5 years ago.

3）how soon:“还要多久才…，多久以后”，答语常用“in＋时间段”。（用于一般将来时）

例1）How soon will she come back?

例2）She’ll come back?in an hour.

4）how far:“多远”，询问距离。

例1）Can you tell me how farit isfrom here to your home

例2）——How faris it from your home to our school

——It’s2 kilometersaway.

句型“It is+adj.+(for sb)to do sth."和“It is+adj.+(of sb)to do sth.区别

"两个句型中，for sb和of sb怎么区别，在使用时要注意adj是说明sb的品质特点的还是说明to do sth的就可以了.

即：说明sb的品质特点用of sb;说明to do sth用for sb.，

简单一句话说就是：说人的用of sb.；说事的用for sb。

for sb.常用于表示事物的特征特点,表示客观形式的形容词，如easy, hard, difficult, interesting, important, impossible等;

如：It's very hard for him to study two languages. 对他来说学两门外语是很难的。

2）of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。

如：It's very nice of you to help me. 你来帮助我，你真是太好了。

例:It is difficult for him to finish the task within two

hours.(difficult 说明完成任务难)

It is kind of you to help me.(kind说明你善良)

across与through区别

across为“横穿”，与“道路”交叉形成“十字”，即：从物体表面经过，如：过河、过桥、过马路。

而through为在立体空间中的“穿过”即：从物体内部经过，如：穿过森林、隧道。

如：go through the forest“穿过森林”；

go across the street “穿过大街”

8. every day与everyday区别

1）every day作状语，译为“每一天”。

如：We go to school at 7:10 every day.我们每天7：10去上学。

I decide to read English every day.我决定每天读英语。

2）everyday 作定语，译为“日常的”。

如：She watches everyday English on TV after dinner.她晚饭后在电视上看日常英语。

What's your everyday activity?你的日常活动是什么？

9.stay up与stay up late区别

1）stay up “熬夜、不睡觉”

如：He stayed up all night to write his story.他熬了一整夜写他的小说。

2）stay up late“熬夜到很晚，迟睡”

如：Don’t stay up late next time.下次不要再熬夜很晚了。

四、语法专项

频度副词

1.定义

表示抽象的次数、频率的副词称为频度副词。

常用的频度副词按频率发生的高低依次为

always>usually>often>sometimes>seldom>hardly ever>never

如：He hardly never exercises.他几乎从不锻炼。

注意：表示具体的次数、频率时，一次用once，两次用twice，三次及以上用“基数词+times”表示。

如：I play soccer twice a week.我每周踢两次足球。

She watches TV four times a week.她每周看四次电视。

2.在句中的位置

1）一般放在实义动词前，be动词、助动词、情态动词之后。

如：We never eat junk food.我们从来不吃垃圾食品。

I can hardly say a word.我几乎说不出一句话来。

He is sometimes very busy.他有时很忙。

2）有些频度副词也可位于句首，但表示不同的含义

①simetimes常用于句首，和位于句中区别不大。

如：Sometimes Jack plays computer games.

②often用于句首时，通常表示强调，且其前一般有quite,very修饰。

如：Very often he goes online.他上网很经常。

③usually有时也可用于句首，其前不用修饰语。

如：Usually my father gets up early.

④always一般不用于句首，但可用于祈使句中。

如：Always remember this.请时刻记住这一点。

3）对频度副词提问时，用特殊疑问词how often。

如：--How often do you exerxise?

--Hardly ever.几乎从不。
