Language points
1.First of all,come and look in the lost and found box!
首先，来看一看失物招领箱。
First of all 是在介绍准备讲的几件事情的第一件事情。用于强调次序。
First of all,let me introduce myself to you.
首先，让我作个自我介绍。
First of all,clean the surface that you are going to paint.
首先，把要刷涂料的表面弄干净。
2.-Whose bag is this?这是谁的书包？
-It's mine.这是我的。
Whose是“谁的”的意思，做疑问代词可单独使用，也可以修饰名词。whose一般式就物主代词或名词所有格提问。如：
Whose bike is this?
Whose is this skateboard?
1)提问部分作定语时，用"Whose+名词+一般疑问句？“结构。如:
It's my skirt.→Whose skirt is it?
这是我的衬衫。→这是谁的衬衫？
2）提问部分作表语时，用"Whose +一般疑问句？”结果。如：
The skirt is mine.→Whose is the skirt?
这件衬衫是我的。  这件衬衫是谁的？
mine 意为“我的”。是名词性物主代词，名词性物主代词有：mine,hers,his,ours,their,its等，在句中作主语、宾语、和表语，后面不需要接任何名词。如：
This football is theirs.
这个足球是他们的。
出现在本课里的类似句子还有：
-Whose gloves are they?
-They're mine!
-Are these crayons yours?
-Yes,they are and this eraser too.
-Is it yours too,Daming?
-No,it isn't.I think it's Betty's.
-Yes,it's hers.
3.Everyone,please be craeful with your things from now on.
各位同学，从现在开始请大家小心保管好你们的物品。
be careful 后接介词with.with后接名词或动名词，表示做某事时很小心或仔细。
如：
He's careful with his work.
他工作很仔细。
Be careful with the vase,it is valuable.
这花瓶很贵，小心点。
Key words and expressions
1.find &lose
find 和lose 都可作及物动词，后面可直接接宾语。find 的意思是“发现；找到”，lose 的意思是“失去‘丢失”。它们是一对反义词。如：
I find an erase on my desk.
我在我的课桌上发现一块橡皮。
People often lose things when they're travelling or when they're in a hurry.
人们在旅行中或是匆匆忙忙时经常丢东西。
【链接】
Come and look in the lose and found box!
过来看看食物招领箱。
lost和found分别是动词lose 和find 的过去分词形式，过去分词可以修饰名词作定语，lost在这里意为“丢失的”，found意为“找到的”，它们作定语修饰名词box.
[Practice】
根据括号内所给含义填空。
1.She can't (find)(找到）her gloves.She often (lose)(丢失）things.
2.I (lost)(丢失）my wallet yesterday;I can't （find）(找到）it everywhere.
2.look for
look for是一个动词短语，意思是“寻找”。由于for是介词，所以后面要接名词或代词作宾语，look for sth.意为“寻找某物”，使用时注意，look for不能分开使用。如：
I can help you look for the wallet.
我可以帮你找钱包。
They are looking for theri phones,cameras,watches,computers and many other things.
他们正在寻找他们的电话、照相机、手表、电脑和其他许多东西。（由于本句中的时态是现在进行时态，所以要将动词look变为现在分词形式，即looking).
[辨析]find和look for的用法
find 和look for都有“找”的意思，但含义不同。find强调“找”的结果，而look for强调“找”的过程。但：
He is looking for his bike.
他在找他的自行车。
I'm looking for my watch,but can't find it.
我在找我的手表，但是找不到。
I hope you will soon find your lost ring.
希望你尽快找到丢失的戒指。
[Practice]
请根据所给汉语意思，完成下列英语句子，每空次数不限.

 I （found）that book under the bed in the end.
2.你在找什么？

3.你昨天找到李明了吗？
-Did you (find)Li Ming yesterday?
没有，我们到处找了，但没有找到他。
-No,we ( looked for)him everywhere,but didn't(find )him.
4.here is/are...
here is/are...这儿有...，....在这儿（用于刚找到某人或某物时），是一个完全倒装句结构。当主语为代词时，用部分倒装。
如：
Here is the address.
这里那里的地址。
Here is an apple.
这儿有一个苹果。
-Could you give me an orange?
