一、科学课老师讲解了关于大气的知识,一起和 Susie 了解一下。
The sky is blue. The clouds are white. Does it mean the air is good? No. Maybe there is ozone(臭氧) pollution. There is some ozone in the air, usually 30 kilometres above the ground. It can protect us from the UV light. But if there is too much ozone near the ground, it becomes a kind of pollution. It is bad for our health. It is also bad for some plants. Smoke from cars and factories can become ozone in strong sunlight. So when it is sunny and hot, there may be more ozone in the air in the city. What can we do? Drive less! If there is too much ozone in the air, stay indoors until sunlight is not so strong.

一、科学课老师讲解了关于大气的知识，让我们和苏西（Susie）一起了解一下。
天空是蓝色的，云朵是白色的。这是否意味着空气质量良好呢？并非如此。这可能意味着存在臭氧污染。空气中通常含有一些臭氧，它们一般存在于距离地面30千米的高空。臭氧能够保护我们免受紫外线的伤害。但如果地面附近的臭氧含量过高，它就会成为一种污染物。这对我们的健康有害，也对一些植物不利。汽车和工厂排放的烟雾在强烈的阳光下会转化为臭氧。所以，在晴朗炎热的天气里，城市空气中的臭氧含量可能会更高。我们能做些什么呢？减少开车出行！如果空气中的臭氧含量过高，就待在室内，直到阳光不再那么强烈。
