重點句子:

often do you exercise? 你(你們)多久鍛鍊一次身體?

解析:How often + 助動詞do(does或did) + 主語 + do sth.?

疑問詞how often是問頻率(多久一次),(在這裏助動詞do(does或did) 是起幫助構成疑問的作用)與一般現在時或一般過去時連用,回答一般是用表示頻率的副詞,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.你們多久到工廠去一次?每星期兩次。

Eg2)——How often does he go shopping?

——He goes shopping once a month.

2.——“What do you usually do on weekends?”

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

解析:第一個do爲助動詞, 在這起幫助構成疑問的作用;而第二個do則是實義動詞。

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.”“你最喜歡什麼節目?”“動物世界。”

for homework , most students do homework every day .

解析:as for...意思是“至於;關於”,常用於句首作狀語,其後跟名詞、代詞或動詞的-ing形式(即動名詞)。

如:As for him,I never want to see him here. 至於他,我永遠不希望在這裏見到。

As for the story,you'd better not believe it. 關於那故事,你最好不要相信。

As for myself, I don’t want to go now. 至於我自己,我現在不想去。

As for the man, I know nothing about him. 至於那個人,我什麼都不知道。

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”;

Eg1)Do you want to go to the movies with me?你想和我一起去看電影嗎?

Eg2)The teacher doesn't want us to eat hamburgers.老師不想讓我們吃漢堡包。

注意:有很多動詞後面用這種結構做動詞的複合賓語,如:

ask sb. to do sth. 叫某人做某事

tell sb. to do sth. 告訴某人去做某事

help sb. (to) do sth. 幫助某人做某事

6. She says it’s good for my health.

解析:be good for...表示“對……有益(有好處)”;

其反義爲:be bad for...。(這裏for 是介詞,後跟名詞、代詞或動名詞)如:

Eg1)It's good for us to do more reading. 多讀書對我們有好處。

Eg2)Reading in bed is bad for your eyes.在牀上讀書對你的眼睛有害。

7. How many hours do you sleep every night?

try doing sth.表示“(用某一辦法)試着去做某事”。如:

eg)You’d better try doing the experiment in another way.你最好試試用另一種方法做這個試驗。

11. My healthy lifestyle helps me get good grades.

解析:help sb.(to) do sth.幫助某人做某事

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

解析:這裏better是well的比較級,而不是good的比較級

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

14. What sports do you play ?

15. A lot of vegetables help you to keep in good health .

16. You must try to eat less meat .

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

17. That sounds interesting.

解析:這是“主語+系動詞+表語”結構的簡單句。

sound(聽起來),look(看起來),smell(聞起來),taste(嚐起來),feel(覺得),seem(好象),grow(變得),get(變得)等詞在英語中可用作系動詞,後跟形容詞作表語。如:

Eg1)It tastes good. 這味道好。

Eg2)The music sounds very sweet. 這音樂聽起來很入耳。

Eg3)The smoke grew heavier and heavier. 煙霧變得越來越濃了。

與之類似的情況:有because就不能再用so.

says it’s good for my health.她說它對我的健康有好處。

解析:be good for對…有益;其反義詞組:be bad for對…有害

如:Eating vegetables is good for your health.吃蔬菜對你的健康有益。

辨析:be good for ,be good at ,be good with

be good for“對…有益”;

be good at“擅長於”;

be good with“和…相處的好”;

如:I’m good at playing football.

Are you good at children?

come?怎麼回事?

解析:表示某件事很奇怪,有點想不通。可單獨使用,也可引導一個問句,相當於疑問詞why.但how come開頭的特殊疑問句使用的仍是陳述語序。

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

=Why didn’t you tell me about it?你怎麼不早點告訴我這件事?

,how about Tuesday?哦,那星期二怎麼樣啊 ?

解析:How about…?=What about …?,“…怎麼樣”,用來向對方徵求意見。

如:It’s very sunny today ,how/what about playing tennis?

ty percent don’t exercise at all.20%的學生根本不鍛鍊。

解析:“not…at all”“一點也不;根本不”

詞語辨析

1.注意sometimes與幾個形似的詞的區別。

(1) sometime是副詞,意爲“在某個時候”,“某時”

例:Will you come again sometime next week?

(2) some time是名詞詞組,意爲“一段時間”,做時間狀語用

例:I will stay here for some time.我將在這呆一段時間。

(3)some times是名詞詞組,意爲“幾次,幾倍”

例:I met him some times in the street last month.上個月我在街上遇到他好幾次了。

(4)sometimes 是頻度副詞,意爲“有時”=at times

例:He sometimes goes skateboarding on weekends.他有時週末去滑滑板。

意爲“時間”時,爲不可數名詞。

意爲“次數,倍數”時,爲可數名詞,

例1:What time is it?

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

注意:1)“次數”的表達方法:

一次once;兩次twice;三次或三次以上用基數詞加上times:three times、five times、one hundred times.

2)表示“……幾次”的表達方法是:

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

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

與different

解析:1)same指“相同的”,前面通常要有一個定冠詞the,但是如果same前面已經有this,those等詞,不能再與the連用了。

例:We are in the same class.我們在同一個班級。

結構:the same as 與......一樣 如:

例:His mark is the same as mine.他的分數和我的分數一樣。

2)different譯爲“不同的”,其後的可數名詞應爲複數形式。

例:We are in different classes. 我們在不同的班級。

結構:be different from 與......不同

例:This sweater is different from that one.這件毛衣與那一件不同。

different的名詞形式爲difference, 複數形式爲differences。

4. hard / hardly

1)hard: hard既可作形容詞,也可作副詞。

adj. 辛苦的,困難的

adv. 努力,使勁地

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

例2:It's a hard (adj.) question. (=difficult)這是一個難的問題。

例3:The boy studies very hard (adv.). 那男孩學習非常努力

例4:He works hard. 他努力工作。

結構:It's hard for sb to do sth 做某事對某人來說是難的。如:

例:It's hard for him to finish the work. 完成那項工作對他來說很難。

hardly: adv. 幾乎不,簡直不

例1)I can hardly see it.我幾乎看不到它。

例2)He hardly works. 他幾乎不工作。

反意疑問句:It hardly rains here, does it?

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

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)“(延續)多長時間”,答語常用for+時間段或since+時間點。(用於各種時態);

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

"兩個句型中,for sb和of sb怎麼區別,在使用時要注意adj是說明sb的品質特點的還是說明to do sth的就可以了.

即:說明sb的品質特點用of sb;說明to do sth用for sb.,

簡單一句話說就是:說人的用of sb.; 說事的用for sb。

1)for sb.常用於表示事物的特徵特點,表示客觀形式的形容詞,如easy,hard,difficult,interesting,important

,impossible等;

如:It's very hard for him to study two languages. 對他來說學兩門外語是很難的。

2)of sb的句型一般用表示人物的性格,品德,表示主觀感情或態度的形容詞,如good, kind, nice, clever, foolish, right。

如:It's very nice of you to help me. 你來幫助我,你真是太好了。

例:It is difficult for him to finish the task within two hours.(difficult 說明完成任務難)

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

ss與through區別

1)stay up “熬夜、不睡覺”

如:He stayed up all night to write his story.他熬了一整夜寫他的小說。

2)stay up late“熬夜到很晚,遲睡”
