Good evening.
My name is ·.I’m very glad to stand here to give you a short speech.Today my topic is smile and the world smiles to you.
Please look at my face.Yes I’m smiling.I like smiling ,because it can makes me confident and give me courage.
Smile is important.Can you imagine a world without smiles?Can you bear seeing sad faces here and there?
Of course you can’t!
Smile can bring us many good things.
It’s easier to make new friends through charming and friendly smile.Smile always(can) creates a good impression.Maybe we cannot remember someone’s name after meeting each other for the first time; however,we can’t forget their smile.
It makes strangers become friends.It makes parents and children understand each other better.
Sometimrs you may meet with storms in life and it may hurt you deeply.You will feel sad and disappointed.Yes ,that’s something which can't be avoided.But you should smile after being upset.Only smile can help you to get over the problems.
As (As可以去掉）a popular saying goes,“Failure teaches success”（这句话改成Failure is the mother of success-失败是成功之母也可以）.
There are many successful people in the world.Most of them had faced serious problems less or more before they succeeded.Just like Steven Hawking,Marie Curie and so on.Why did they become so successful,the answer is (that)no matter how untoward they are,they still smile.You see ,smile can lead you to success.
We should not only smile to difficulties but also smile to people who need it.smile is like the light in darkness.there are some people who complain why the life is so dull and boring.When wemeet them ,what we could do is to show our nice smile.It makes people see hope in desparate situations.
It makes people feel warm in ice and snow.It gives thirsty people power to walk on in a dessert(desert才是沙漠).It makes cowards become brave .
So please remember,smile make your life brighter.Smile and the world smiles with you.（结尾加一句that's all,thanks可能会更好）我的一点浅见,请你自己斟酌吧
