自主学习 探究新知
（一）学习新单词
pen,pencil,pencil box,book,ruler,eraser,schoolbag,dictionary
1、英汉互译。
your dictionary his backpack my ruler

（二）学习新句型
--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指示代词，“这”，“那”。它们只表达单数概念。
（2) this 是就近指代，而that是相对的远处指代，这只是一个相对概念，并不是绝对的。
(3)这两个指示代词经常单独使用，从不和冠词(a, an, the)、形容词性物主代词(her, his, its, my)等连用；
(4)它们的一般疑问句在回答时不直接用this, that, 而是用it来代替上文的指示代词以免词汇重复。
(5) 它们还可以放在名词前面，直接作宾语，但只与单数名词在一起使用。
This is my pen,that is his book.这是我的钢笔，那是他的书。
-Is this your backpack? 这是你的背包吗？
-Yes, it is. /No, it isn’t. 是，是的。/不，不是。
2.不定冠词a, an 的用法区别：
(1)不定冠词an 常用于元音发音开头的词前。例如：
an eraser 一块橡皮擦，an apple 一个苹果， an “A” 一个A字母
(2)不定冠词a常用于可数名词前表示数量，相对于“one”一个/本。a book 一本书、a pencil case 一个铅笔盒。
3.名词性物主代词的用法：
主格人称代词 宾格人称代词 物主代词
形容词性 名词性
I
you
he
she
it
we
you
they
(1)人称代词的主格在句子中作主语
A. am sorry， I am late. B. are both from China.(we)
(2).人称代词的宾格在句子中作动词宾语或介词宾语，表语。
A. Who is it? It is (I).
B. I like (she).What about (you)?
(3).形容词性物主代词一般位于名词前，用作定语。
A. (I)name is John Green.
B. Excuse me, is this (you)car?
(4).名词性物主代词的句法功能A. 作主语，例如：May I use your pen? works better.我可以用一用你的钢笔吗？
B. 作宾语，例：I love my motherland as much as you love .
我爱我的祖国就像你爱你的祖国一样深。
C. 作表语，例如：Is this your book or (I)?
D. 名词性物主代词=形容词性物主代词+名词:为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词+名词”的形式。例：My bag is yellow, her bag is red, his bag is blue and your bag is pink.为避免重复使用bag，可写成My bag is yellow, is red, is blue and is pink.
E. 名词性物主代词有时可以和of 构成短语，
a. A friend of (I)is good at English.
b. I hate that behavior (行为)of (her).
c. That photo of (you) is beautiful.
