【 指點迷津 】

單元重點詞匯點撥

1 . pingpong 乒乓球

〖 點撥 〗乒乓球也可說 table tennis .

She plays pingpong very well . 她乒乓球打得很好。

2 . hard-working 努力工作的

He is a hard-working teacher . 他是一位勤奮的老師。

〖 點撥 〗類似的詞如：peace-loving愛好和平的。

3 . happily 幸福地，快樂地

The children are playing happily . 孩子們正愉快地玩著。

〖 點撥 〗該詞為 happy 的副詞形式，作狀語。happiness是其名詞形式。注意：live a happy life過著幸福的生活。

4 . easily 容易地，輕易地

We did it easily . 我們很容易地把它做了。

〖 點撥 〗其形容詞為 easy .

It is easy for sb to do某人干……很容易。It is easy for her to bring the books here .

5 . carefully 仔細地，小心地

Listen to the teacher carefully ! 仔細聽老師講 !

〖 點撥 〗該詞為 careful 的副詞。careless粗心大意的。carefully =with care認真地。

You’d better do your homework carefully .

6 . worried 擔心的，煩惱的

〖 點撥 〗注意 worry 可作動詞和名詞“擔心，焦慮”，be worried about =worry about “對…感到擔心”。

－ What’s the matter with you , Tom ?

－ My parents haven’t been back yet . I am worried about it .

單元詞組思維運用

1 . telephone number 電話號碼

What is your telephone number . 你的電話號碼是多少 ?

Perhaps his telephone number is wrong .

－ Is this 9998345 ?

－ Sorry , you have the wrong number .

2 . do some shopping 買些東西

We\'re going to do some shopping . 我們打算購買一些物品。

〖 提示 〗類似詞組還有：do sport 從事運動 / do the cooking 烹調，烹飪 / do washing 洗衣服 / do cleaning 做掃除 / do one\'s homework 做家庭作業  / do one\'s lesson 做功課

Mr . Smith likes doing sport after meals . 史密斯先生喜歡飯后參加體育運動。

Is Rose going to do washing this afternoon ?

I don’t like to do shopping with her this afternoon , Mum .

3 . Please help yourself 請隨便吃，請自己動手 ( 拿、吃、抽煙等 )

Please help yourself to wine . 請隨便用酒。

〖 提示 〗表吃什么，拿什么時，該詞組要加介詞 to 再加賓語。

Boys , help yourselves to more bananas and oranges .

Sir , help yourself to some cigarettes (香煙).

注意：help sb with幫助某人干…… 。She always helps me with my Chinese on Sunday .

4 . get ready for 為……做好準備，為……準備好

Have you got ready for the party ? 這個聚會你已經準備好了嗎 ?

〖 點撥 〗get ready to do準備好干…… 。Please get ready to run , class .

5 . on the other side of 在……的另一邊

On the other side of the river there are some banana trees . 在河的對岸，有許多香蕉樹。

On the other side of the street there is a book shop .

〖 提示 〗指兩者之中的另一邊。

6 . like to do 與 like doing：

〖 提示 〗這兩者都表示“喜歡做什么”。區別如下：

like to do 指喜歡做特定的或某次具體的行動，指一時的愛好。

I like to swim in the river . 我喜歡在這條河游泳。 ( 特定場合的具體行動 )

( 試比較：I like swimming . 我喜歡游泳。 )

like doing 指喜歡做某事，即長期的愛好和興趣。試比較：

Do you like swimming ? 你喜歡游泳嗎 ? ( 指長期的愛好 )

Would you like to swim with me tomorrow ? 你愿意明天和我一起去游泳嗎 ? ( 特指明天一次具體行動 )

另外：如果用于否定結構，like to do 與 like doing 就沒有什么區別，可以換用。如：

I don\'t like smoking =I don\'t like to smoke . 我不喜抽煙。

7 . like 與 would like 的區別：

〖 提示 〗like ( 喜歡，愛好 ) ，后接名詞、代詞、不定式或動名詞。

Do you like fish ? 你喜歡 ( 吃 ) 魚嗎 ?

would like 意為“想要，愿意”解時，是 wish 和 want 的意思。用于禮貌性地提出要求或表示愿意提供幫助。其后可接名詞、代詞、動詞不定式。但不能接動名詞。

Would you like something to eat ? 你想吃點什么東西嗎 ?

would like sb to do愿意讓某人干 ……。

My father would like me to go to Beijing with hin this summer .

二、學海導航

【 學法指要 】

單元句型思路明晰

1 . as + 副詞 + as

Read this passage as quickly as you can . 你盡快讀完這段短文。

這具句型中第一個 as 為副詞，第二個 as 為從屬連詞，引導程度狀語從句。又如：

He ran as fast as he could . 他盡力地快跑。

He works as hard as you . 他與你一樣努力工作。

2 . Not… 否定主語的句型

Not everyone likes sandwiches . 不見得每個人都喜歡三明治。

not 無論放在句首或句子其它地方，與 all , every 等詞連用時，只表示部分否定，又叫做“部分否定句”。如：

Everyone does not like sandwiches . 每個人不見得都喜歡三明治。

Not everyone is a worker . =Everyone is not a worker . 不見得每個人都是工人。

Not everyone agrees with you . 不是人人都同意你的意見。

Not all people agree with you . 不是大家都同意你的看見。

單元難點疑點釋疑

1 . What can I do for you ? 你要點什么 ?

這是對顧客的禮貌用語，還可以說 Can I help you ? 如：

— What can I do for you ? 你要點什么 ?

— I want to buy a new coat . 我想買件新上衣。

— Can I help you ?

— Two cups of coffee . =Two coffees . 請來兩杯咖啡。

2 . She felt worried . 她很焦急。

feel 是連系動詞， worried 是形容詞，在句中作表語。turn , get , look , be 等動詞也是連系動詞，都可接形容詞構成系表結構。如：

He felt happy . 他很高興。

The trees turn green . 樹兒綠了。

※ 表示具有某種性質、特征或處于某種狀態。常用的有 be , appear , feel , sound , seem , book , smell , taste 等。例如：

It is not late . 時間還不晚

The dish smells good . 這道菜聞著香。

He seemed to be writing something . 他好象在寫什么東西。

His words sounds all right . 他的話聽起來有道理。

※ 表示動詞所敘述的動作和過程所產生的結果；或者表示狀態的變化。常用的有：get , go , come , become , turn , grow , fall , prove , run , make 等。例如：

The custom has now become a rule . 那習俗已變為成規。

The milk in the cup will go bad . 杯子里的牛奶要壞了。

Her face turned red .

※ 某種持續的狀態。常用的有：keep , continue , stand等。例如：

She knew she must keep calm . 她知道她必須保持鎮靜。

※ 除 make 等個別詞外，幾乎所有的連系動詞都能接形容詞作表語。例如：

Our country is getting stronger and stronger . 我們國家日益強大。

※ 接名詞作表語的有：become , get , look , make , seem , turn 等。例如：

Now you look a grown-up young man . 現在你看上去已經是一個成年的小伙子了。

One tree does not make a wood . 獨木不成林。

He used to be a soldier till he turned writer . 他當作家之前曾是戰士。

※ 我們還應注意某些連系詞和形容詞的固定搭配及其褒貶色彩。比如，come 多接褒義形容詞，而 go 則多接貶之形容詞。例如：

come true / right 變為現實 / 正確

go bad / hungry / mad / blind / deaf / tired / …變壞 / 餓 / 瘋 / 瞎 / 聾 / 累……

grow rich / tall / large / clever / old…變得富裕 / 高 / 大 / 聰明 / 年老……

fall ill / asleep / silent / …生病 / 睡著 / 沉默……

3 . I\'m worried about my party . 我正擔心晚會呢 ?

be worried about 意為“為……而擔心”。注意該詞組表示擔憂的狀態。如：

Mother is worried about his health . 母親擔心他的健康。

Are you worried about the meeting ? 你擔心開會的事嗎 ?

4 . I\'ll get another one now . 我現在再拿一根來。

one ( s ) , other ( s ) the other ( s ) 及 another 的區別：

one 有下列幾種意思：1 ) 可指人或表示一種；2 ) 常用來代替前面剛提到的可數名詞，以

避免重復，如可數名詞為復數，就要用 ones 來代替；3 ) 表示“一個…，另一個…”用“one…the other…”。

the others 表示其余的幾個，要用定冠詞 the。

others 表示泛指“別人”或“別的東西”，常不加定冠詞。

another 意為“另一個，又一個”強調三個或三個以上人 ( 或事物 ) 中的“另一個”。

試比較：

A：Which sweater would you like , the red one or the blue one ? 你想要哪件毛衣，紅色的還是藍色的 ?

B：The red one . 紅色的。

I have two sisters . One is a teacher , the other is a doctor . 我有兩個姐姐，一個是教師，另一個當醫當。

The children are cleaning the classroom . Some are sweeping the floor , others are cleaning the window . 孩子們在打掃教室，一些正在掃地，另一些在擦窗子。

Lei Feng was always ready to help others . 雷鋒總是樂于助人。

Here are three pencils . One is red , another is blue , the third is yellow .

這里有三支鍋筆，一支是紅色的，另一支是藍色的，還有一支是黃色的。

單元語法發散思維

簡單句

在句子中應注意謂語動詞和主語在人稱和數上必須一致。

1 ) 主語 + 不及物動詞 ( 謂語 )

The moon rose . 月亮升起來了。

另外：在這種句型中，主語可被定語修飾。謂語常被副詞、介詞詞組等修飾，用來說明動作的程度、時間、地點、狀況等。如：

The sun rises . 太陽升起來了。

The red sun rises . 紅太陽升起來了。

The red sun rises in the east . 紅太陽在東方升起。

2 ) 主語 + 及物動詞 + 賓語

All my friends like to study English and Chinese .

另外：及物動詞除必須有賓語外，還可有修飾語，這點與不及物動詞相同。修飾動詞的狀語通常放在句末。這些狀語多數是副詞或介詞短語，也可用名詞短語、不定式短語、分詞短語等。賓語可以是名詞、代詞、不定式等。如：

They speak English quite well . 他們英語講得好。 ( 副詞作狀語 )

3 ) 主語 + 連系動詞 + 表語

My brother is a singer .My mother is a nurse .

另外：在這個句型中，連系動詞以 be 動詞為最多，此外還有 look , become , keep , get , turn 等。表語可以是名詞、代詞、形容詞、介詞短語等。

It\'s getting colder and colder . 天氣越來越冷。

Please keep quiet ! 請保持安靜 !

單元能力立體檢測

※ 英漢互譯

1 . 白天 2 . 時常 3 . 繼續 4 . 去散步

5 . 打電話給…… 6 . get warm 7 . at the moment 8 . by the way

9 . feel happy 10 . take - away food

答案：1 . day - time 2 . at times 3 . go on 4 . go for a walk 5 . ring up 6 . 變暖 7 . 此刻 8 . 順便說一下 9 . 感到高興 10 . 熟食

※ 要點分析

1 . Now you can ______ the food at home .

A . do B . making C . cook D . doing

答案 C . do , make , cook 都含有“做”的含義，但用在食物上則只用 make 和 cook , make 側重于面食的制作，如包餃子，做蛋糕等，而 cook 側重“烹飪”，句中 can 為情態動詞，后加動詞 cook 原形。

2 . I saw him ______ the car , and he went into that shop .

A . getting on B . getting into C . getting off D . getting out of

答案 D . 上、下小汽車時不用 get on / off 短語，而要用 get into / out of , 另外前后兩分句由 and 連接為并列句，前后動作應一致，不可能上了小汽車又進了商店，所以應選擇下車，即 getting out of。

3 . There ______ water in the bottle .

A . is no B . is not C . are no D . are not

答案 A . water 為不可數名詞，謂語動詞要用單數形式，因此可排除C、D項，另外 no =not any , any 用來修飾 water 不可缺，因此不能只用 is not , 而要選A . is no。

4 . I didn\'t know why she ______ worried .

A . is B . felt C . looks D . feeled

答案 B . 在主從復合句中，除主句為一般現在時的情況外，主從句在時態上一律要保持一致，本題主句為一般過去時，因此從句也要用過去的時態，D項中 feeled 為一種錯誤的過去式形式，因此選B。

5 . Miss Liu will never be late , ______ ?

A . won\'t she B . will Miss Liu C . is she D . will she

答案 D . never 為否定副詞，意為“從來沒有”因此陳述部分為否定句，那么反意疑問句的疑問部分要用肯定形式 will，主語 Miss Liu 相對應的人稱代詞為 she，因此選D，類似這種情況的詞還有 hardly ( 幾乎不 ) ，few , little ( 幾乎沒有 ) ，nobody , no one ( 沒有人 ) ，nothing ( 沒有什么 ) 等。

※ 詞形變化

1 . day ( 反義詞 ) 2 . long ( 比較級 )

3 . snow ( 現在分詞 ) 4 . cloud ( 形容詞 )

5 . happy ( 副詞 ) 6 . country ( 復數 )

7 . stop ( 過去式 ) 8 . beautiful ( 最高級 )

9 . stop ( 第三人稱單數 ) 10 . we ( 名詞性物主代詞 )

答案：1 . night 2 . longer 3 . snowing 4 . cloudy 5 . happily 6 . countries 7 . stopped 8 . most beautiful 9 . stops 10 . ours
