1. Welcome back to school, everyone! 欢迎大家回到学校！
★Welcome此处用着感叹词，“welcome (back) to +地点名词/ welcome +地点副词” 表示“欢迎（回/来）到某地来”。如：
Welcome to Shanghai. 欢迎来到上海。
Welcome home 欢迎回家。
★Welcome 也可以做名词，意为“欢迎”，give sb. a warm welcome “热烈欢迎某人”。 如：
They gave a warm welcome to us.
他们热烈欢迎我们。
拓展记忆：You’re welcome 常用来回答对方的感谢，意思是“不客气”。
2. First of all, come and look in the lost and found box! 首先，过来看看失物招领箱吧！
★first of all意思是“首先，重要的是”，常放在句首做状语，强调首要的事情或动作。如：
First of all ,you should finish your homework.
首先，你应当完成你的作业。
First of all, let me introduce my friend Lily to you.
首先，让我向你介绍我的朋友莉莉。
3. There are a lot of things in it. 里面有许多东西。
★本句为there be 句型，表示“某处有某物”。
①如果there be 后为可数名词单数或不可数名词，be 用is；若为可数名词复数，be 用are。如：
There is a boy in the classroom. 教室里有一个男孩。
There is some water in the glass. 玻璃杯里有些水。
There are many beautiful flowers in the garden.
花园里有许多美丽的花。
②如果there be 后的主语包含两者或两者以上，be的形式适用就近原则，即be与离他最近的主语在数上保持一致。如：
There is a book and two pens on the desk.
桌子上有一本书和两只钢笔。
There are two pens and a book on the desk.
桌子上有两只钢笔和一本书。
4. Whose bag is this 这是谁的书包？
★whose 是疑问代词，意为“谁的”，其后接名词的单数或复数，引导特殊疑问句，用于提问物品的所有者。常用句子结构：whose +名词+谓语动词+其他？如：
Whose pen is that 那是谁的钢笔？
Whose flowers are these 这些是谁的花？
Whose are those books 那些书是谁的？
5. Here’s a purple wallet. 这儿有一个紫色的钱包。
★此句为倒装句，有here, there, out, in, down等表示方位的副词开头的句子中，如果主语是名词要用全部倒装语序，即谓语动词位于主语之前；如果主语是人称代词，则常用部分倒装。如：
Here are some flowers. 这儿有一些花。
There goes the bell. 铃响了。
Here she comes! 她来了！
6. Look at the nice watch. 看这块漂亮的手表。
【辨析】look, look at, see, watch, read
①look为不及物动词，后面不能带宾语，常单独使用，以引起对方注意。如：
Look! That’s an English car. 看！那是一辆英国的小汽车。
②look at是由动词look 与介词at组成的词组，相当于及物动词，后面可带宾语，侧重“看”的动作。如：
Look at the blackboard, please.请看黑板。
③see为及物动词，意思是“看见”，侧重“看”的结果。如：
Can I see your new pen 我可以看看你的新钢笔吗？
④watch 是及物动词，意思是“观看、注视”，用来指注视移动着的物体，如看电视、看球赛、看戏等。如：
They are watching TV. 他们正在看电视。
⑤read是及物动词，意思是“阅读，读懂，理解”，也可以表示“看（书、报纸、杂志等）”。如：
Mary often reads on Sundays. 在每个星期天玛丽常常读书。
7. Everyone, please be careful with your things from now on. 从现在开始，请每个人小心保管自己的物品。
★be careful with 意思是“注意……；小心（对待）……；对……小心/谨慎”。be careful 意为“小心，当心”可单独使用，相当于watch out，也可在其后面接with短语或动词不定式形式。如：
Be careful not to lose your money. 小心不要丢了你的钱。
Be careful (Watch out)! The car is coming. 小心！车子来了。
Be careful with that knife, or you’ll cut yourself.
小心那把刀子，否则你会划伤自己。
★from now on意思是“从现在起/开始”。如：
Try to do do better from now on. 从现在起，尽量做的好些。
I’m going to study hard from now on.
我打算从现在开始努力学习。
From now on, things are going to be different around here.
从现在起，这附近的情况将发生变化。
拓展记忆：from today/ tomorrow/then on 从今天/明天/那时开始
Listen to the tape and follow it.
Then read it together.
Welcome back!
Please be careful with … from now on.
