Go and watch the baby when he is asleep.See how his chest rises and falls，then rises and falls again.

He doesn’t know what he is doing。but he breathes as well as the oldest and cleverest man in the

world.He began to breathe when he was born。and he will not stop until he dies.He does it without thinking about it.

See how long you can hold your breath.

In some places men dive into the sea for pearls(珍珠).They pick up shells that hold the pearls，and the longer they stay under water，the more pearls they can find.So they hold their breath as long as they can.

Watch how many times a man draws his breath every minute.Some men breathe fifteen times a minute.An elephant breathes only eight times.It was told that a mouse breathes a hundred and twenty times each minute.

No one needs to tell us what we breathe in every minute is air.It is around us everywhere.

Dear David，

I am very upset(焦虑)and I need some help.You know 1 will finish my college study soon，and I must decide about my future.I am outgoing and good at speaking.I love to talk with others.So 1 want to be a TV reporter.

But everyone in my family has a different idea about my future.I don’t know how to choose.My father says I should go to England to study.My mother says I should be a doctor like her.And my brother wants to start a computer company(公司)with me.My sister is a singer，so she asks me to learn to sing from her.And my uncle works on a farm.He says I earl work with him on his farm.

So.it is very difficult for me to decide which one is better.

What do you think?

Write to me soon.

Yours,

Michael
