九年級Unit 2 重難點解析

1. [原文]Have you ever watched someone surf? (L. 6)surf是動詞,在這裡怎麼用原形?

[精析] surf是省去to 的動詞不定式,在這裡作感官動詞watch的賓語補足語。類似用法還有,感官動詞look at, see, listen to, hear, 使役動詞let, have,make等,後都可以接省去to的不定式作賓補。

2. [原文] Now it is enjoyed by people all over the world. (L. 6) is enjoyed是什麼謂語形式?all over是什麼用法?

[精析]is enjoyed是被動語態形式。當主語為動作的承受者時,謂語要用被動語態形式,即be + 過去分詞形式。這部分內容在今後還要學到。

all over是“全部、渾身、在各地”的意思,可單獨使用,也可在其後接相應的詞語。例如:

People all over the world love peace.全世界的人民都熱愛和平。

He is wet all over.他全身都溼了。

all over the world 也可以用all the world, the whole world 來表示,但一定要注意冠詞的位置。用all 時,冠詞放在all之後,用whole時,冠詞放在whole之前。

3. [原文] Every act large numbers of tourists to the islands. (L. 6) large numbers of與a large number of 有區別嗎?

[精析]沒有。這兩個短語都表示“許多”的意思,可以互換。如:Large numbers of / A large number of people came to the meeting from all over the country. 許多來自全國各地的人蔘加了會議。但是a number of / numbers of 與the number of是有區別的。作主語時,前者後接複數名詞,謂語用複數形式;後者意思是“為……的總數”,後接複數名詞,但謂語要用單數。試比較:

A number of students are playing in the playground.許多學生在操場上玩。

The number of students in the playground is about one hundred.操場上的學生(數量)大約有一百人。

4. [原文] For example, Jake Booth, a 21-year-old man, gave up his job in San Francisco a year ago. (L. 6) 21-year-old中的year怎麼不加s?

[精析] 21-year-old是由數詞 + 名詞 + 形容詞構成的複合形容詞,其中year不可以用複數形式,詞與詞之間用連字號。試比較:

He is a 15-year-old boy.他是一個15歲的男孩。

The boy is 15 years old.這個男孩15歲。

另外,句中give up意思是“放棄”,作及物動詞,後可以接動名詞;也可以接代詞,用賓格放於up之前。也可用作不及物動詞。例如:

You should give up smoking. I gave it up last year.你應該戒菸。我去年就戒掉了。

She doesn't give up easily.她做任何事情都不會輕易放棄。

5. [原文] Although I haven't got a very good job, surfing keeps me very fit.( L. 6) although與though用法相同嗎?

[精析] 有共同之處,也有不同點。兩都可用來引導讓步狀語從句,表示漢語的“雖然……但是……”。但不能說although /

【考點一】 No matter ____you come, you will always be welcome.

A. what B. how

C. when D. whether

[思路解析]本題譯為:“無論你什麼時候來,你都是受歡迎的。”應該用when。所以本題答案為C。

[知識拓展] No matter who (what, how, why, when, where, if, whether,how many,how much...)無論誰(什麼,怎麼,為什麼,什麼時候,哪裡,是否,多少……)在句中作讓步狀語。可放句首,也可放句末。如:

a) You can' t go in, no matter who you are. 不管你是誰,都不能進去。

b) Don' t trust him, no matter what he says or does.不管他說什麼或做什麼,你都不要相信他。

c) No matter where you go, we'1l always be together. 不管你去哪裡,我都和你在一起。

d) Mary always got to school on time, no matter if she went without breakfast. 瑪麗不管是否吃了早飯,她都是準時趕到學校

【考點二】 He has been to Beijing twice. (對劃線部分提問)

_________has he been to Beijing?

A. How long B. How often C. How soon D. How many times

[思路解析] 本句的意思是“他去過北京兩次”,對次數提問,疑問詞應用how many times,故本題答案為D。

[知識拓展] 1) how often是對動作發生的頻率進行提問。如:

-How often do you have to take the medicine?這藥需要多久服一次?

-Three times a day. 日服三次。

2) how long表示動作持續的時間。如:

-How long have you studied here? 你在這兒學習多久了?

-I have studied here for nearly 3 years .我在這兒學習近3年了。

3) how soon表示再過多久,一般用將來時態。如:

-How soon will you go to Beijing? 你再過多久去北京?

-I'll go to Beijing in two weeks.再過兩週我就去北京了。

【考點三】 -Who jumps_________in your class?

-Li Ming. He cleared the 1.6 meter mark last week.

A. high B. highest C. the most highly D. tallest

[思路解析] high表示“高的,高地”,既可以作形容詞又可以作副詞。highly adv. 表示“高度地,極為讚許”等,在這裡表示跳得高,要用 high,又根據in the class所以用最高階,選B。

[知識拓展] think highly of somebody 意思是“高度評價某人”,speak highly of somebody意思是“稱讚某人”。tall主要用來表示形容人或物的高低。

【考點四】 It is dark, but they go on_________. They never usually work so late, though they worked late last night.

A. work B. to work C. worked D. working

[思路解析] go on doing sth.意為“繼續做某事”,go on to do sth.意為“接著做另外一件事”。根據題意,本題答案為D。

[知識拓展] 1) go on doing sth.是“繼續做同一件事情,可能中間有間斷”。如:

I'll stop here. Please go on reading. 我就說到這兒,請接著讀吧。(老師在學生讀的過程中插話)

2) “繼續做某事”還可以用go on with sth. 來表示。如:

Go on with your work. 繼續工作。

3) go on to do sth.通常表示“接著做另一件事”。如:

Stop writing now and go on to read the next passage. 別寫了,接著讀下一段。
