【 指點迷津 】
單元重點詞匯點撥
1 . house 房子
There is a house near the river .
Our new house is different from yours in colour .
〖 點撥 〗 house 的復數(shù)為 houses , 其讀音為［&127;h?÷?÷］，house 指的是用來居住的所有建筑物，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(fā)音比較特殊。注意其單數(shù)與復數(shù)的變化。又如：man - men男人。
3 . children 是 child 的復數(shù)形式
The children in that family are all at school . 那家的孩子們都在學校里上學。
Children of school-age must go to school . 學齡兒童必須上學。
〖 點撥 〗 注意其發(fā)音和單復數(shù)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 ? 每天你什么時候上班 ?
〖 點撥 〗 作 “ 工作 ” 解，work 為不可數(shù)名詞。上班 go to work , 下班 after work 。 work hard at 努力干 ……
We go to work at 7：30 .
5 . pioneer 先鋒
They are pioneers of our farm . 他們是我們農(nóng)場的開路先鋒。
〖 點撥 〗注意該詞的發(fā)音和拼寫。the Young Pioneers少先隊員。
單元詞組思維運用
1 .已經(jīng)學習的介詞短語回眸
in the river 在河里 / in the tree 在樹上 / in the picture 在圖片里 / in Row 1在第一排 / in Class 3 , Grade 1 在 1 年級 3 班 / at home 在家里 /at school 在學校里 / in the workbook 在練習冊里 / on the desk在書桌上 / behind her chair在她的椅子后面 / under the chair 在椅子下面 / in her pencil - box 在她的鉛筆盒里 / on the floor在地板上 / in your desk 在你的桌子里 / at Li Lei's bedroom 在李雷的臥室里 /on the wall 在墻上 /under the window 在窗下 / behind the door 在門后 / in Hebei 在河北 / in your bag 在你的書包里 ( 袋子里 ) / 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 在樹后 / in the box 在盒里子 / on the clothes line 在曬衣繩上 / on the bed 在床上 / in the car 在轎車里 / near the river 在河邊
2 . in our classroom 在我們的教室里
Who is in our classroom ? 誰在我們的教室里 ?
There is a map of China in our classroom . 我們教室里有一張中國地圖。
We are having a lesson in the classroom . 我們正在教室里上課。
3 . on the teacher's desk 在講臺上

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
She is always at work on Sundays . 她星期天總是在工作。
介詞 at 在這里是 “ 從事 ”。如 What are you at ? 相當于 What are you doing ? ( 你正在干什么 ? )
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 . 房里一點燈光也沒有。
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(yè)時間夠嗎 ?
對這類句型的回答可根據(jù)實際情況選擇肯定回答或否定回答。
肯定回答為：Yes there is/are .
否定回答為:No , there isn't/aren't ( any ) 。
3 . 問有多少的句型
How many + 可數(shù)名詞復數(shù) + 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(shù)名詞進行提問，對不可數(shù)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 . 在房子后面有一棵樹。
behind the house “ 在房子后面 ” ，是介詞短語作狀語，一般放在句尾。有時放在句首 是為了表示強調(diào)。
例如：a . On the wall there is a map . 墻上有一幅地圖。
b . Near the river there is a house . 河邊有一所房子。
c . There is a cat under the tree . 樹下有一只貓。
2 . Are there any birds in the picture ? 畫中有鳥嗎 ?
any 形容詞，一般用于疑問句和否定句中，后面可接可數(shù)名詞和不可數(shù)名詞。例如：
a . Is there any water in the glass ? 杯里有水嗎 ? ( water 是不可數(shù)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(tài)，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(shù)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 ? 畫上有幾只 ( 多少只 ) 小船 ?
( 1 ) 在由 how many 構成的特殊疑問句中，how many 后常跟可數(shù)名詞的復數(shù)形式。how many 和它后面的復數(shù)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(jù)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 ? 河里有幾條小船 ?
-There are five . 有五條。
-How many birds are there in the tree ? 樹上有幾只鳥 ?
-There's only one . 只有一只。
-How many students are there in the classroom ? 教室里有多少學生 ?
-There aren't any . 沒有學生。

三、智能顯示
【 心中有數(shù) 】
單元語法發(fā)散思維
A. 需要掌握的名詞復數(shù)的發(fā)音
1 . 名詞的復數(shù)形式
( 1 ) 以 “ 輔音字母 + y ” 結尾的名詞，變 y 為 i，再加 es 。如：baby - babies , family - families ,city - cities 。
( 2 ) 不規(guī)則名詞的復數(shù)形式 ( 需特別記住 )
man - men woman - women , child - children , tooth - teeth（牙） 。
( 3 ) 加 - es 構成的復數(shù)形式以及以 ce , se , ze , ( d ) ge 結尾加 - s 構成的復數(shù)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 為 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(shù)英語單詞仍保存了古英語中的復數(shù)形式，它們的構成是不規(guī)則的，發(fā)音也有相的變化。例如： man → men woman → women child → children
注意：house 的復數(shù)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(shù)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、復數(shù)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(shù)量的詞提問，習慣用法是：How many + 名詞 ( 復數(shù) ) + 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 ?
