    【 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 的發音比較特殊。注意其單數與復數的變化。又如:man - men男人。

    3 . children 是 child 的復數形式

    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 〗 注意其發音和單復數的變化。

    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 ? 每天你什么時候上班 ?

    〖 點撥 〗 作 “ 工作 ” 解,work 為不可數名詞。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

    There are some flower on the teacher's desk .

    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

    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 + 可數名詞復數 + 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。

    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,后面可接可數名詞和不可數名詞。例如:

    a . Is there any water in the glass ? 杯里有水嗎 ? ( 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 后常跟可數名詞的復數形式。how many 和它后面的復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。

    【 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向往。這真是:誰不說俺家鄉好,稻谷飄香,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. 需要掌握的名詞復數的發音

    1 . 名詞的復數形式

    ( 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 ) 不規則名詞的復數形式 ( 需特別記住 )

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

    ( 3 ) 加 - es 構成的復數形式以及以 ce , se , ze , ( d ) ge 結尾加 - s 構成的復數形式,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 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 ) 還有少數英語單詞仍保存了古英語中的復數形式,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 的復數形式的讀音應[′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、復數形式,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 ( 復數 ) + 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 ?
