【 指點迷津 】

單元重點詞彙點撥

1 . house 房子

There is a house near the river .

Our new house is different from yours in colour .

〖 點撥 〗 house 的複數爲 houses , 其讀音爲［&127;h?÷?÷］，house 指的是用來居住的所有建築物，包括 room ( 房間 ) 、浴室、起居室等。

2 . women 是 woman 的復形式

I don't know how many women will come to the tea party . 我不知道有多少位婦女會來參加茶話會。

〖 點撥 〗 women 的發音比較特殊。注意其單數與複數的變化。又如：man - men男人。

3 . children 是 child 的複數形式

The children in that family are all at school . 那家的孩子們都在學校裏上學。

Children of school-age must go to school . 學齡兒童必須上學。

〖 點撥 〗 注意其發音和單複數的變化。

4 . work 工作，勞動

Work hard and be a good boy . 努力學習，做個好孩子。

You should work hard at English .

What time do you go to work every day ? 每天你什麼時候上班 ?

〖 點撥 〗 作 “ 工作 ” 解，work 爲不可數名詞。上班 go to work , 下班 after work 。 work hard at 努力幹 ……

We go to work at 7：30 .

5 . pioneer 先鋒

They are pioneers of our farm . 他們是我們農場的開路先鋒。

〖 點撥 〗注意該詞的發音和拼寫。the Young Pioneers少先隊員。

單元詞組思維運用

1 .已經學習的介詞短語回眸

in the river 在河裏 / in the tree 在樹上 / in the picture 在圖片裏 / in Row 1在第一排 / in Class 3 , Grade 1 在 1 年級 3 班 / at home 在家裏 /at school 在學校裏 / in the workbook 在練習冊裏 / on the desk在書桌上 / behind her chair在她的椅子後面 / under the chair 在椅子下面 / in her pencil - box 在她的鉛筆盒裏 / on the floor在地板上 / in your desk 在你的桌子裏 / at Li Lei's bedroom 在李雷的臥室裏 /on the wall 在牆上 /under the window 在窗下 / behind the door 在門後 / in Hebei 在河北 / in your bag 在你的書包裏 ( 袋子裏 ) / under your bag 在你的書包下面 ( 袋子下面 ) / on the hill 在山上 / under the black bike 在黑色的單車上 / behind the tree 在樹後 / in the box 在盒裏子 / on the clothes line 在曬衣繩上 / on the bed 在牀上 / in the car 在轎車裏 / near the river 在河邊

2 . in our classroom 在我們的教室裏

Who is in our classroom ? 誰在我們的教室裏 ?

There is a map of China in our classroom . 我們教室裏有一張中國地圖。

We are having a lesson in the classroom . 我們正在教室裏上課。

3 . on the teacher's desk 在講臺上

4 . near the door 在門邊

Don't stand near the door . 別站在門邊。

The student near the door is Li Ming . 門邊的那個學生叫李明。

5 . at work 在工作，在上班

介詞 at 在這裏是 “ 從事 ”。如 What are you at ? 相當於 What are you doing ? ( 你正在幹什麼 ? )

二、學海導航

【 學法指要 】

單元句型思路明晰

1 . 存在句

There be + not + 主語 + 其他

There isn't any light in the room . 房裏一點燈光也沒有。

There aren't any lesson this morning . 今天上午沒有課。

There is no fire without some smoke . 有火必有煙；有利就有弊。

Be there + 主語 + 其它 ?

Are there any apples in the basket ?

Is there a bird in the tree ?

Is there enough time for me to do all the homework ? 我要做完全部的作業時間夠嗎 ?

對這類句型的回答可根據實際情況選擇肯定回答或否定回答。

肯定回答爲：Yes there is/are .

否定回答爲:No , there isn't/aren't ( any ) 。

3 . 問有多少的句型

How many + 可數名詞複數 + are there + 其他 ?

How many days are there in a week ?

How many students are there in your school ?

How many policemen are there in the street ?

how many 是對可數名詞進行提問，對不可數名詞用 how much 。如：How much time do you spend ?

單元重點難點釋疑

1 . Behind the house there is a tree . 在房子後面有一棵樹。

behind the house “ 在房子後面 ” ，是介詞短語作狀語，一般放在句尾。有時放在句首 是爲了表示強調。

例如：a . On the wall there is a map . 牆上有一幅地圖。

b . Near the river there is a house . 河邊有一所房子。

c . There is a cat under the tree . 樹下有一隻貓。

2 . Are there any birds in the picture ? 畫中有鳥嗎 ?

any 形容詞，一般用於疑問句和否定句中，後面可接可數名詞和不可數名詞。例如：

a . Is there any water in the glass ? 杯裏有水嗎 ? ( water 是不可數名詞，句中用 is , 不用 are 。 )

b . Are there any boats in the picture ? 畫中有船嗎 ?

c . There aren't any flowers in the picture . 畫中沒有花。

3 . They are at work . 他們在工作。

at work 在 “ 工作中 ” ，介詞 at 在此表示狀態，這是一個固定詞組，在這類詞級事， 名詞前不用冠詞。類似的還有：

at school 在上學，在求學 。 at table 在吃飯，at home在家 ，at play 在玩耍，

例如：a . My English teacher's son is at school . 我們英語老師的孩子在上學。

b . Mary and Tom are at play under the tree . 瑪麗和湯姆在樹下玩耍。

c . Some workers are at table . 一些工人們在吃飯。

d . My mother is at home . 我媽媽在家。

4 . Young Pioneer 少先隊員

該詞組是名詞詞組，有專有名詞，所以兩詞的首字母都要大寫。但表示幾位少先隊員時，不 定冠詞或數詞不大寫。例如：a Young Pioneer 一位少先隊員，ten Young Pioneers 十位少先隊員，some Young Pioneers 一些少先隊員

5 . What about cats ? ＝Are there any cats ? 有沒有貓 ?

6 . How many boats are there in the picture ? 畫上有幾隻 ( 多少隻 ) 小船 ?

( 1 ) 在由 how many 構成的特殊疑問句中，how many 後常跟可數名詞的複數形式。how many 和它後面的複數名詞是一個完整的詞組，不能分開。例如：

How many boys are there in your class ? 你們班有多少個男孩 ?

How many trees are there in the picture ? 畫上有多少棵樹 ?

( 2 ) 在回答 how many 構成的特殊疑問句時，根據具體情況有三種回答：

回答：有幾個 ” ，用 There are …

回答 “ 只有一個 ” ，用 There is ( only ) one .

回答 “ 沒有 ” ，用 There aren't any . 例如：

-How many boats are there in the river ? 河裏有幾條小船 ?

-There are five . 有五條。

-How many birds are there in the tree ? 樹上有幾隻鳥 ?

-There's only one . 只有一隻。

-How many students are there in the classroom ? 教室裏有多少學生 ?

-There aren't any . 沒有學生。

【 妙文賞析 】

My home

My home is in a small village near our town . The village is at the foot of a hill . The hill is very beautiful . There are many trees and flowers on it . And there is a river at the foot of the hill , too . In summer , I like swimming in the river with my friends . At home I have a good friend . It’s a dog . Its name is Huahua . Every day when I come back from school , it always comes over to me .

I like my home very much . Do you like it ? I hope I have more friends . Do you want to be my penfriend (筆友)?

賞析：作者用簡樸的語言把自己的家鄉描繪的令人嚮往。這真是：誰不說俺家鄉好，稻穀飄香，鳥兒歡唱，人勤地豐，這都離不開當的好領導。

三、智能顯示

【 心中有數 】

單元語法發散思維

A. 需要掌握的名詞複數的發音

1 . 名詞的複數形式

( 1 ) 以 “ 輔音字母 + y ” 結尾的名詞，變 y 爲 i，再加 es 。如：baby - babies , family - families ,city - cities 。

( 2 ) 不規則名詞的複數形式 ( 需特別記住 )

man - men woman - women , child - children , tooth - teeth（牙） 。

( 3 ) 加 - es 構成的複數形式以及以 ce , se , ze , ( d ) ge 結尾加 - s 構成的複數形式，讀［iz］。這樣的單詞如：buses boxes watches oranges

( 4 ) 以輔音字母 + y 結尾的詞，變 y 爲 i , 再加 - es , - es 讀［ｚ］。例如：

baby →babies family → families

注意：如 y 前是元音字母，則只能加 - s 。例如： day → days play → plays

( 5 ) 還有少數英語單詞仍儲存了古英語中的複數形式，它們的構成是不規則的，發音也有相的變化。例如： man → men woman → women child → children

注意：house 的複數形式的讀音應［′ｈａｕｚｉｚ］，而不是［′ｈａｕｓｉｚ］

B. There be 結構

( 1 ) there be 的否定句一般用 a 或 any 或數字。例如：

There isn't a river in the picture .

There aren't any picture on the wall .

( 2 ) there be 的一般疑問句如有 “ 一些 ” ，一定有用 any 。如：Are there any trees in front of the house ?

( 3 ) there be 的特殊疑問句

1 ) 對 there be 結構中作主語的名詞提問，無論是單、複數形式，習慣用法是 What's + 某 地，中間不用 there 。例如：

What's under the desk ? There's a ball under the desk .

What's in the room ? There are many desks in the room .

2 ) 對 there be 結構中表示數量的詞提問，習慣用法是：How many + 名詞 ( 複數 ) + are there + 某地 ( 某時 ) 。例如：

There is only an apple on the desk .

How many apples are there on the desk ?

There are seven days in a week .

How many days are there in a week ?
