5A Unit 1单元要点
一基础知识部分：（要求：会读、会背、会默）
1 单词（详见单词表上本单元单词）
二语法知识部分：（要求：理解运用）
1 There be 句型
在英语中，如果要表示某地有或存在某物或某人时，常用句型There is /are +人/物+地点来表达。

在这个句型中，is和are 的选用取决于后面的主语的单复数形式。

如：There is a house in the forest.
There are three houses in the forest.
There is a desk and some chairs in the classroom. （如果there be 后有多个
主语，be 动词的选用取决与第一个名词，这叫做就近原则）
2there be 和have 在意义和用法上的区别
there be 表示“存在”，而have 则表示“拥有”。

如：There is an English book on the desk.
I have an English book.
3. Help! Help! 来人啊！救命啊！
当遇到紧急情况时，我们通常用Help!做呼救语。

4.cannot=can’t
cannot是can的否定形式，主要用于书面语。

在口语中一般用其紧缩形式can’t.
如：Bobby cannot see any cakes in the fridge.
5.There be 的否定句
there be 结构的否定式是在动词be后面加not 构成。

如：There isn’t a chair in the living room.
There aren’t any cakes here.
6.some和any 在用法上的区别
some 和any 都表示一些，可以修饰可数名词的复数或不可数名词
some 多用于肯定句，any 多用于否定和疑问句。

三拓展部分：（要求：根据老师要求，认真完成）
Deep in the forest, lived three bears, Father Bear, Mother Bear and Baby Bear.
One day, Mother Bear made some porridge (粥) for breakfast.
“My porridge is too hot,” said Father Bear.
“Mine（我的）too!”cried（cry的过去式，哭）Baby Bear. “It burnt（burn 的过去式，烧伤）my mouth!”
Mother Bear had an idea. “Let’s go for a walk and wait for（等待）the porridge to cool down（冷却）, ” she said.
So, the three bears set off（出发）into the woods.
Someone else had decided（decide的过去式，决定）to go for a walk that day, too. A little girl named Goldilocks was skipping（跳跃）down the path（小路）towards the bear’s cottage（小屋）.
“How pretty,” she said. “I wonder who lives here?”
Goldilocks peeped（peep的过去式，偷看）through the door and saw（see的过去式）three bowls on the table. “Porridge, I love porridge!” she cried.
First , the little girl tried Father Bear’s porridge. “This is much too hot,”said Goldilocks. Then , she tried Mother Bear’s porridge. “This is too sweet,” she said.
Baby bear’s porridge was just right, so the hungry girl gobbled （gobble的过去式，狼吞虎咽）it all up!
Goldilocks was now so full that she had to sit down!
First, she tried Father’s Bear’s chair. “This is too hard.” she groaned（groan的过去式，抱怨）. Then, she tried Mother Bear’s chair. “This is too soft,” she moaned.
Finally, Goldilocks sat in Baby Bear’s tiny chair.
“This one is just right!” she cried, happily.
Suddenly, the chair broke and she fell on the floor!
Goldilocks was tired now, so she climbed the stairs（楼梯）to the bedroom. There, she found（find 的过去式）three cosy（舒适的）beds.
Feeling sleepy, she climbed on to Father Bear’s bed.
“This is too hard,”she said. Then, she tried Mother Bear’s bed. “This is too soft!” she cried.
Baby Bear’s little bed was a perfect fit and soon, Goldilocks was fast asleep.
When the three bears returned（return 的过去式，返回）from their walk , they couldn’t believe（相信）their eyes!
“Who’s been eating my porridge?” roared Father Bear.
“Who’s been eating my porridge?” cried Mother Bear.
“And who’s been eating my porridge and gobbled it all up?” howled（howl的过去式，嚎哭）Baby Bear.
The three bears looked around （环顾四周）their house.
“ Who’s been sitting in my chair? ” growled Father Bear.
“ Who’s been sitting in my chair?” said Mother Bear.
“ And who’s been sitting in my chair and broken it into pieces?” sobbed（sob的过去式，呜咽）Baby Bear.
The three bears went（go的过去式）up the stairs to their bedroom.
“ Who’s been sleeping in my bed?” said Father Bear.
“Who’s been sleeping in my bed? ” asked Mother Bear.
“ And who’s still sleeping in my bed?” cried Baby Bear.
Suddenly, Goldilocks woke up!
Father Bear and Mother Bear chased（chase的过去式，追逐追赶）the little girl out of the house and into the woods.
“Go home and don’t come back!” they shouted.
Mother Bear made（make的过去式）some more porridge and the three bears never did see naughty Goldilocks again.。
