In summer， especially between 10 a.m. and 3 p.m. of the day， people are easily be burned by the sun’s rays. How to avoid the sun’s rays effectively？
Using sunscreens
It is one of the most important ways to protect your from the strong sunlight. You’d better use sunscreen 15 to 30 min. before going outside. It should be applied on all exposed skin， which includes lips， nose， ears， neck， hands， feet and eyelids. Try not to put it in the eyes because it can irritate them. You also need to note① that before or after swimming， you need to apply the sunscreen on your skin， because the sun’s rays can pass through the water easily.
Wearing sunglasses
Sunglasses can help you prevent your eyes from sunlight’s damage. When you buy sunglasses， you’d better check whether they can protect you from the two kinds of rays， UVA and UVB.The ideal sunglasses are those that can block 99 to 100 percent of the UVA and UVB radiation. You need not concern yourself about how dark② the glasses are， because the UV protection comes from an invisible chemical applied to the lenses， not from the color of the lenses. Otherwise， the large-framed wraparound sunglasses are better because they can protect your eyes from sunlight coming from all angles.
Wearing hats
The ideal sun hat has at least 3-inch brim③ allaround because it can protect the skin exposed to the sun such as the neck， ears and eyes.
Covering-up
Every time when you go out， you’d better put on a light， loose and long-sleeve shirt， pant or long skirt if possible. Most of the materials and colors of clothing can absorb④ or reflect⑤ UV-rays.

怎样防止太阳晒伤
在夏季，尤其是每天上午10点到下午3点的时候，人们很容易被太阳的光线灼伤。如何有效防晒伤？
涂防晒霜
涂防晒霜是防晒的重要方法之一。每次外出前，最好提前15到30分钟涂好防晒霜。而且所有暴露的皮肤都应该涂到：包括嘴唇、鼻子、脖子、手、脚以及眼睑。要注意的是防晒霜不要碰到眼睛，因为它会刺激眼睛。还需要注意的是，在游泳前后需要涂抹，因为太阳光线能轻而易举地穿透水面。
戴太阳镜
太阳镜会保护你的眼睛不受阳光的伤害。在买太阳镜时，你最好检查一下它是否有防止两种紫外线（紫外线A和紫外线B）的功能。理想的眼镜是能锁住99～100%紫外线A和B。你不必过于关心它的颜色是否深，因为防止紫外线侵入的是涂在镜片上的一种看不见的化学物质，而不是来自镜片的颜色。否则的话，你可能觉得宽边眼睛更适合你，因为它可以遮挡从不同角度射来的阳光。
戴太阳帽
较为理想的太阳帽的帽檐至少为3英寸，这样才能保护露在阳光下的皮肤：如脖子，耳朵，眼睛等部位。
遮好全身
如果有条件的话，每次出门最好穿上浅色宽松长袖衫、长裤或者长裙。因为大多数布料的材料和颜色都能很好的吸收或反射紫外线。
