感歎句的類型:

⑴ What a∕an+adj+可數名詞單數 (+主語+謂語)!

What +adj+可數名詞複數∕不可數名詞 (+主語+謂語)!

What a fine day (it is) !多麼好的天啊! (day為可數名詞單數)

What an interesting book it is !多麼有趣的一本書啊!(book為可數名詞單數)

What beautiful flowers they are !多麼漂亮的花啊! (flowers為可數名詞複數)

What bad weather it is!多麼糟糕的天氣啊!(weather為不可數名詞)

⑵ How +adj +主語+(謂語中的)系動詞! How +adv +主語+(謂語中的)實義動詞!

How happy I am!我多麼高興啊! (happy為adj,am為系動詞)

How hard they are working !他們工作多麼努力啊!(hard為adv,work為實義動詞)

點撥:陳述句改為感歎句,可以採用“一判、二定、三移”。

一判:是判斷出陳述句謂語動詞後的中心詞的詞性(adj∕adv∕n);

二定:是根據判斷出來的結果來確定引導詞(中心詞為名詞用What;中心詞為形容詞或副詞用How;)

三移:就是把主語和謂語移到後面。

注意:在感歎句中,不得出現so,very,very much等表示程度的單詞。

例如:①Our school is beautiful 。

一判:beautiful為形容詞;二定:beautiful為形容詞,用How 來引導;三移:把Our school is移到How beautiful後面,即為感歎句How beautiful our school is!

②He is a clever boy.

一判:boy為名詞;二定:boy為名詞,用What來引導;三移:把He is移到What a clever boy 後面,即為感歎句What a clever boy he is!

③He studies English well.

一判:well為副詞;二定:well為副詞,用How 來引導;三移:把He studies移到How well後面,即為感歎句How well he studies!

練習:將下列句子變為感歎句。①The room is very bright.

② We live a happy life today. ③It is a nice present.

④This is difficult problem. ⑤She played the piano wonderfully.

(best) way to do sth:做某事的()方法

a trip參加郊遊,at the end of this month在本月底

forward to +名詞代詞:期待,盼望

from sb.收到某人的來信 = receive a letter from sb.

opening of… :開幕/開業

II. 例題

例1 Do you know any other foreign language____ English?

A except B but C beside D besides

解析:A、B兩項except等於but,意為“除了…”,C-beside意為“在…旁邊”,不符合題意。而D-besides, 意為“除了…之外,還有”。所以該題正確答案為D。該題意為:除了英語外,你還知道別的語言嗎?

例2 He suddenly returned ____ a rainy night.

A on B at C in D during

解析:我們均知道,at night這一短語,但如果night前有修飾詞,表具體的夜晚,則要用介詞on來修飾,故該題正確答案為A。

例3 I'm looking forward ____your letter.

A to B in C at D on

解析:該題正確答案為A。look forward to 為固定搭配,意為“期望、盼望”。

1、形容詞的用法

形容詞是用來修飾、描繪名詞的,通常在句中作定語、表語或賓補,有時還可作狀語。如:

He is honest and hardworking.

I found the book interesting.

某些形容詞與定冠詞連用表示一類人作主語時,謂語通常用複數形式。如:

The rich and the poor live in different parts of the city.

The English like to be with their families.

多個形容詞作定語修飾名詞的順序:

冠詞+序數詞+基數詞+性質狀態(描述性)+形狀大小+新舊老少+顏色+國籍+材料+名詞。如: the second five interesting big new red Chinese wall papers.

2、形容詞比較等級的形式

(1) 規則形式

一般説來,單音節詞及少數雙音節詞在後加-er; --est 來構成比較級和最高級;其他雙音節詞及多音節詞在前加more, most.如:

great-greater-greatest

busy-busier-busiest

important-more important-(the)most important

(2) 不規則形式

good (well)-better-best

bad (ill)-worse-worst

many (much)-more-most

little-less-least

(3) 形容詞比較等級的用法

①表示兩者的比較,用形容詞的比較級+than. 如:

He is cleverer than the other boys.

This one is more beautiful than that one.

②表示兩者以上的比較,用“the +形容詞最高級(+名詞)+of(in) …”如:

He is the cleverest boy in his class.

③表示兩者是同等程度,用“as +形容詞原級+as”. 如:

He is as tall as I.

I have as many books as you.

④ 越… 越…

例如:The more I learn, the happier I am.

⑤ You can never be too careful. 越小心越好

又如:You can never praise the teacher too highly.

你怎麼讚揚這個老師也不過分。

⑥ I have never spent a more worrying day.

(2) 地點副詞 如:here, there, near, around, in, out, up, down, back, away, outside等。

(4) 程度副詞 如:almost, nearly, much, greatly, a bit, a little, hardly, so, very等。

2、副詞比較等級的用法

其用法與形容詞相似,只是副詞最高級前可省略定冠詞。如:

Of all the boys he sings (the) most beautifully.

We must work harder.

3、某些副詞在用法上的區別

(1) already, yet, still

already表示某事物已經發生,主要用於肯定句;yet表示期待某事發生,主要用於否定句和疑問句;still表示某事還在進行,主要用於肯定句和疑問句,有時也可用於否定句。如:

We've already watched that film.

I haven't finished my homework yet.

He still works until late every night.

(2) too, as well, also, either

too, as well和 also用於肯定句和疑問句,too和as well多用於口語,一般放在句末,而also多用於書面語,一般放在句中與動詞連用。either用於否定句和否定的疑問句,往往放在句末。如:He went there too.

He didn't go there either.

I like you as well.

I also went there.

(3) hard, hardly

hardly意為“幾乎”與hard在詞義上完全不同。如:

I work hard every day.

I can hardly remember that.

(4) late, lately

lately意為“最近、近來”,late意為“晚、遲”。如:

He never comes late.

Have you been to the museum lately?

例1 Tom's father thinks he is already ____

A high enough B tall enough

C enough high C enough tall

解析:該題正確答案是B。修飾人高用tall, 而建築物的高用high,並且enough修飾形容詞要放在形容詞後面。因此該題選B。

例2 ____ the worse I seem to be.

A When I take more medicine

B The more medicine I take

C Taking more of the medicine

D More medicine taken

解析:該題正確答案為B。“the+形容詞比較級+… , the +形容詞比較級+…”意為越…,越…。該句意為:吃的藥越多,我的病越是加重。

例3“I haven't been to London yet”.

“I haven't been there ____”.

A too B also C either D neither

解析:該題正確答案為C。A和B都用於肯定句中。D-neither本身意為否定“兩者都不”,而C-either則用於否定句中,意為“也”。

例4 Mr Smith was ____ moved at the news.

A deep B deeply C very deep D quite deeply

解析:該題正確答案為B。A. deep用於副詞時,修飾具體的深,如dig deep,而B-deeply則修飾表示感情色彩的詞,如該題為deeply moved.另如deeply regret等。而D-quite和deeply均為副詞,不能互相修飾。
