Topic 1: Directions: You’ll be given 6 minutes to have a discussion about “??Do you know PM2.5? What can college students actually do to get our blue sky back？” based on the picture below. Recently, the air is very poor, a lot of people wear masks.Are the result of the PM2.5,What is the PM2.5，Do you know? 我知道，PM2.5就是环境空气中空气动力学当量直径小于等于 2.5 微米的颗粒物。它能较长时间悬浮于空气中。虽然PM2.5只是地球大气成分中含量很少的组分，但它对空气质量和能见度等有重要的影响。 I know .the air in the air of dynamics equivalent diameter less than or equal to 2.5 micron particles. It can be a long time suspended in the air.Although PM2.5 is only a few components content of earths atmospheric composition, but it has important effect on visibility and air quality etc. C、与较粗的大气颗粒物相比，PM2.5粒径小，面积大，活性强，易附带有毒、有害物质，且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响更大。 Compared with coarser of atmospheric particulates, PM2.5 particle size is small, the area is large, the activity is strong, easy with poisonous and harmful substances, and stay in the atmosphere longer, transmission distance, and to human health and the impact of atmospheric environment quality. 既然对人体有害，那我们就应该减少它，那么我们应该怎样做呢？如何使我们头顶的天空回复蓝色？ Since harmful to human body, that we should try to reduce it, then how should we do?How to make the reply in blue sky over our heads?

E、我认为如果想让天空变蓝，我觉得我们可以多种值植物，因为植物叶片具有较大的表面积，能够吸收有害气体和吸附PM2.5，还能产生有利气体，虽然吸收效率低，但这的确是一个不错的治理方法。 I think if you want to make the sky blue, I think we can plant a variety of values, because the plant leaves with a larger surface area, can absorb the harmful gas adsorption and PM2.5, also can produce favorable gas, while the absorption eff
