總課時(shí)：5課時(shí) 課題：Unit3 section A 1a-2c (1課時(shí))

作課教師及班級: 秦曉峰 馮林麗 李林艷 （七年級）

一、學(xué)習(xí)目標(biāo)（目標(biāo)定向 情景激趣）

（一）學(xué)習(xí)目標(biāo)

1．掌握詞匯pen,pencil,dictionary，ruler,eraser,schoolbag等。

學(xué)會(huì)句型:

--Is this your pencil? --Yes, it is. It’s mine. /No it isn’t. It’s his.

--Are these your books? --No, they aren’t. They are hers.

3. 掌握指示代詞:this,that

4. 掌握名詞性物主代詞，并復(fù)習(xí)鞏固人稱代詞的主格和賓格及形容詞性物主代詞。

自主學(xué)習(xí) 探究新知

（一）學(xué)習(xí)新單詞

pen,pencil,pencil box,book,ruler,eraser,schoolbag,dictionary

1、英漢互譯。

your dictionary his backpack my ruler

我的鉛筆盒 他的卷筆刀 她的書 一塊橡皮

（二）學(xué)習(xí)新句型

--Is this your pencil? --Yes, it is. It’s mine. /No it isn’t. It’s his.

--Are these your books? --No, they aren’t. They are hers.

1、this, that的用法。

（1）this, that指示代詞，“這”，“那”。它們只表達(dá)單數(shù)概念。

（2) this 是就近指代，而that是相對的遠(yuǎn)處指代，這只是一個(gè)相對概念，并不是絕對的。

(3)這兩個(gè)指示代詞經(jīng)常單獨(dú)使用，從不和冠詞(a, an, the)、形容詞性物主代詞(her, his, its, my)等連用；

(4)它們的一般疑問句在回答時(shí)不直接用this, that, 而是用it來代替上文的指示代詞以免詞匯重復(fù)。

(5) 它們還可以放在名詞前面，直接作賓語，但只與單數(shù)名詞在一起使用。

This is my pen,that is his book.這是我的鋼筆，那是他的書。

-Is this your backpack? 這是你的背包嗎？

-Yes, it is. /No, it isn’t. 是，是的。/不，不是。

2.不定冠詞a, an 的用法區(qū)別：

(1)不定冠詞an 常用于元音發(fā)音開頭的詞前。例如：

an eraser 一塊橡皮擦，an apple 一個(gè)蘋果， an “A” 一個(gè)A字母

(2)不定冠詞a常用于可數(shù)名詞前表示數(shù)量，相對于“one”一個(gè)/本。a book 一本書、a pencil case 一個(gè)鉛筆盒。

3.名詞性物主代詞的用法：

主格人稱代詞 賓格人稱代詞 物主代詞

形容詞性 名詞性

I

you

he

she

it

we

you

they

(1)人稱代詞的主格在句子中作主語

A. am sorry， I am late. B. are both from China.(we)

(2).人稱代詞的賓格在句子中作動(dòng)詞賓語或介詞賓語，表語。

A. Who is it? It is (I).

B. I like (she).What about (you)?

(3).形容詞性物主代詞一般位于名詞前，用作定語。

A. (I)name is John Green.

B. Excuse me, is this (you)car?

(4).名詞性物主代詞的句法功能A. 作主語，例如：May I use your pen? works better.我可以用一用你的鋼筆嗎？

B. 作賓語，例：I love my motherland as much as you love .

我愛我的祖國就像你愛你的祖國一樣深。

C. 作表語，例如：Is this your book or (I)?

D. 名詞性物主代詞=形容詞性物主代詞+名詞:為避免重復(fù)使用名詞，有時(shí)可用“名詞性物主代詞”來代替“形容詞性物主代詞+名詞”的形式。例：My bag is yellow, her bag is red, his bag is blue and your bag is pink.為避免重復(fù)使用bag，可寫成My bag is yellow, is red, is blue and is pink.

E. 名詞性物主代詞有時(shí)可以和of 構(gòu)成短語，

a. A friend of (I)is good at English.

b. I hate that behavior (行為)of (her).

c. That photo of (you) is beautiful.

3、單項(xiàng)選擇：

（ ）1. -____ this your book? -No, it isn't.

A. Are B. Is C. Am D.be

（ ）2. -Is that his pen? - ____________.

A. Yes, it is B. No, it is C. Yes, it isn't D./

（ ） 4. -Hello! Are you Sue? -_____________________

三、合作探究（展示交流 互動(dòng)解惑）

(一）小組內(nèi)對自主學(xué)習(xí)的單詞和句型互相討論、交流解決疑惑

（二）小組競賽,利用自己所有的物品小組編新對話進(jìn)行展示
