The Sun‘s radiation can be harmful to us as well.We can‘t see it,but ultraviolet(紫外线) radiation comes from the sun along with heat and light.You can not see ultraviolet radiation,but it influences our health.Ultraviolet radiation is what burns our skin.
Ultraviolet radiation has three parts:ultraviolet radiation A,ultraviolet radialion B,and ultraviolet radialion C.Waves of ultraviolet radiation A and B may cause harm to our body when we get sunburned.The harm to our body can give us skin cancer(皮肤癌) and cause other health problems.
You can help to protect yourself from ultraviolet radiation by wearing sunscreen(防晒霜),sunglasses and hats.
Try to stay out of the sun when it is especially strong.You can find out ultraviolet radiation levels by watching the weather report on television.

77.Does the sun‘s heat burnour skin?___
78.How many parts are there in ultraviolet radiation?___
