Traditional presents
In the West, people often take flowers
when they visit someone. Different flowers
have different meanings. For example, people
often give red roses to someone they love.
In Greece, you must not give white flowers because that means that someone is dead.
When you go to a foreign country, it is always best to check what people usually do, so you do not make mistakes.

What must they wear
What mustn’t they talk about
What can’t they do
What presents can they bring
When must they arrive
…

11. Show the advice your group chose in Activity 10 to the whole class. Put the pieces of advice together to
form the advice of the whole class.
12. Then send your advice to your foreign friends or post it on your class blog.
1. You need not take them off. But in some other countries you must not wear shoes in the house.
(1) take off 脱掉。它是动副型短语，宾语是名词时，可放在take与off之间或off之后；宾语是代词时，必须放在take与off之间。
例：You must take off your shoes before you go into the room in Japan.
在日本，你进入房间前必须脱掉鞋。
(2)【辨析】wear与put on
wear侧重指穿的状态，意为“穿/戴着”，可用于穿衣、戴眼镜、戴项链等。put on意为“穿上”，强调穿衣服的动作。
例：Mary wears a red skirt and I want to put on my red skirt, too.
玛丽穿着红裙子，我也想穿上我的红裙子。

探究二

情态动词 must, can, need, had better
must的否定形式 mustn’t表示禁止，意思是“不能，不允许”。如：
—Must I finish the task right now
我必须现在就完成任务吗？
—No,you needn’t.不，你不需要。
You mustn’t come here without permission.
没有允许你不准来这里。
(2)表示肯定的猜测，常用于肯定句中，意为
“一定是，必然……”。如：

2. can的用法
can的否定形式为cannot，缩写为can’t。
(1)表示能力
如：I can’t swim.

They will be able to run this machine on their own in three months. 他们将在未来的3个月自己操作这个机器。
(2)表示可能性，意为“可以，可能”。如：
That big cinema can sit 2,000 people.

This can’t be true. 这不可能是真的。
3. need的用法
need作为情态动词表示“需要”，可用于肯定句、否定句和疑问句。否定形式needn’t比较常用，表示“不需要”或“不必要”。
如：You needn’t wait.
你不需要等待。
【注意】need也可以作为行为动词，表示“需要”，常用need to do sth.结构。如：
I need to clean my room immediately.
我需要立即打扫我的屋子。
4. had better的用法
(1) had better表示劝告或建议，意为“最好……”。如：
You’d better speak in a low voice.
你最好低声说话。
(2) had better 一般不用于疑问句中，但可用于否定句中，
其否定形式为 had better not。如：
You’d better not go out before you finish your homework.
在你完成家庭作业之前，最好不要出去。
