(OPEN)a video of domino
When you walk under sunlight without any protection, the UV from sunlight will destroy our skin cells by a chain reaction as the domino show. Day after day, your skin color will become dark, you will have more wrinkles and even more seriously, you may have skin cancer.
(Body)
Does it mean we should stay in the house all the day time? Absolutely not! Part of UV light will trigger some nutrition synthesis in skin, such as Vitamin D. And even if you stay in the house, you still expose to about 50% of UV light.
So what we should do is to put the stopper in the chain reaction! First of all, let's know more about UV light. We can divide UV into three categories, UVA, UVB and UVC. UVC will be absorbed by the ozone layer. And UVA has the weakest energy but will stimulate the production of melanin and tan our skin. The elastin and collagen will lose from your skin after exposing to UVA for a long time. So that you'll have wrinkles and your skin will lose its elasticity. Therefore, UVB will let you get sunburn, stimulate more melanin to produce and dry your skin. So no matter you're male or female, skin protection work is quite important to both of you!
So the targets of sun protection are UVA and UVB. And I will share two strategies with you.
Firstly, choose the right color to wear. According to the research, black clothes will screen out 91% of UV light while white clothes made of the same material will not intercept any UV light. So if you need to walk or drive under sunlight it's better to wear dark color of clothes.
Secondly, apply effective sunscreen. How can you tell effective sunscreen?
1. Read the sun protection label on the production.
SPF means sun protection factor. It's an index of its ability to absorb UVB.
And you can estimate the effective time of the sunscreen by this formula:
The time your skin getting inflamed without any protection × SPF factor
Some people will use fifteen minutes multiply SPF factor as a rough estimation.
PA means Protection Grade of UVA and can represent its ability against UVA.
PA+ means slightly UVA interceptive.
PA++ means medium UVA interceptive.
PA+++ means highly UVA interceptive.
So it'll be better to select PA+++ sunscreen if you need to do outdoor activities.
2. Find the effective composition.
It's the most important point for selecting sun block. There are two major types of the effective compositions.
(1) UV scatter: They will reflect UV, such as TiO2 and ZnO.
(2) UV absorbent: They will absorb UV, such as Cinnamates, Salicylates and Benzophenones.
Please check the ingredient of your sunscreen to make sure the effective compositions are included. Or it won't protect you from UV light even if it's very expensive.
(CONCLUSION)
Come closer! Come closer! You can come much closer! Would you like to look as young as me? You don't need to buy the expensive SKII. Just protect your skin by the right way! UV, stop!

C9 speech (Persuade with power , 5 to 7 minutes)
Title: I believe I can
“ I believe I can fly, I believe I can touch the sky…..” every time when I hear the song, I always feel that belief can make anything possible. Human is the most intelligent and creative animal, so they will create something to help their dreams come true. For example, they want to fly in the sky, they create airplane, for visiting other planet, they create space shuttle. We make everything impossible to possible, do you ever think about why we can make it? I thought about it. Because we have dreams, and we have belief, in order to make our dreams materialized, so we set our goals, and force ourselves to achieve it. And I believe the most pathetic is the one who doesn’t have dream, he even doesn’t have any goal in his life, it’s really waste of time, and even will hurt other people.
Why do I say that? I remember a story, three men lost in the desert, one day when they are walking, they find a magic lamp, so they rub the magic lamp and there comes a genie. He says “ Oh~ thanks for set me free, then each of you can make a wish, then I will make your wish come true.” A says I wish I can have a lot of money and send the money and I back to my country. Then he is gone. B think a while and says I wish I can have many beautiful women and send the women and I back to my country. Then he is also disappeared. Then C talk to genie that I don’t have any wish, just give me some wine, so the genie give him and ask “ Are you sure you don’t want any wish?” then he says drink alone is lonely, I wish my those two friends are here. Then all of them still back to the desert. See~ does he hurt other people? Don’t laugh, the story has part two. The other day when they are finding the way out, they find the magic lamp again, and they still rub the lamp, and still comes out a genie. The genie still give each of them a wish. Due to last experience, so A and B let C to make a wish first, C still talk to genie that he doesn’t have any wish, just give him some wine, and the genie give him and ask “ Are you really sure you don’t have any wish?” then he replies that I really don’t have any wish, so you can go now. Then the genie is disappeared.
Most of us always think what we have, then we will do something, and become the person you want to be. But actually, it’s totally inverse. You should set a goal about what kind of people you want to be then you do something, then you will have what you want. For example, like join toastmaster, you can’t think
I don’t have English abilities, so I can’t join it. You should think I would like to be one of the great speakers, so I want to join toastmaster, then I will have my English abilities, right? We also read some news that junkman donate money to tsi-chi or orphanage, although they don’t have lots of money, but they still do the charity. Why? Because they want to be the one to help others. Having dreams is important, and believe in yourself is important, too. To motivate your potential, to create your own value, that’s the most important. So what’s your dream? What’s your belief? Just do it now~
