Ⅱ.阅读

A

A smile will tell people around you that you are a kind and friendly

person.However，many people don't smile because they think they have ugly teeth.For

example，one of my classmates，Mike，doesn't have very nice teeth，so that is why he

seldom opens his mouth.He even says that he has lost confidence because of his

teeth.So it is very important for us to look after our teeth.In fact，a lot of people have

this problem.Some people inherit tooth problems from their parents，while others' teeth

are damaged because of bad habits，like heavy smoking，eating too much sugar or not

brushing teeth often.If your teeth are in bad shape，you should see a dentist and ask for

help.They can help improve your teeth and tell you how to take care of them.

Smiling can help you feel more confident and make people think of you as a more

friendly person.If you want to keep healthy，you should not only smile but also

laugh.An Indian doctor called Kataria said that young children should laugh about 30

times a day，while adults should laugh between 7 and 15 times a day.So please take this

chance to smile and laugh now.

If you want to succeed in life，you need to express the proper body language，with

or without having to say anything else.You will certainly notice a whole new reaction

from people if you use the power of body language.

Relax your shoulders，keep your hands at your sides (never inside your pockets)

and breathe slowly.Have a warm，welcoming facial expression as if you look forward to

communicating.Depending on the situation，you may smile when appropriate.

Face the other person or your audience and keep eye contact as much as possible

throughout the talk.Nodding and tilting (倾斜) your head closer can show that you are

listening.

Do not fold (交叉) your arms，look down at the floor or put your hands in your

pockets.These can show that you are uninterested.If you have any comments，you can

show them in negative but respectful ways like raising your eyebrows.

A lot of your body language can show how confident，interested，bored，angry or

nervous you are.Keeping your head up throughout the entire conversation can show that

you are very much into the conversation at hand.

You may feel free to use a few hand gestures to emphasize (强调) a point.If you're

enumerating things，it's better to use each of your fingers as you mention each item to

help your audience keep track.

Pacing will help you create more ground if you have a larger crowd to

communicate with.It will also show confidence on your part as you think of more things

to say.

Be very careful when touching the other person since you are crossing the

boundaries (界限) of body language through actual contact.Remember that in body

language，it is your body that does the talking for you.
