我们都生活在北京，对北京的环境，空气质量都心知肚明，北京的雾霾太严重了，那么北京的雾霾具体有多严重呢？网上有一组数据表明，北京最严重的PM2.5的浓度，甚至可以达到1000毫克每立方米，这是多么骇人的一个数字！长期暴露在PM2.5的环境中，会导致心血管疾病，呼吸道疾病的高发。对于这么严峻的形式，我们的政府、企业、市民，都贡献了自己的力量来保护我们的环境。
2017年3月5日上午，李克强总理在政府工作报告中明确指出了：“要坚决打好蓝天保卫战”，此外，政府还出台了一系列政策来推动市民的绿色生活。
去年冬天，一批批造型炫酷，耐用好奇，扫码骑走的共享单车横空出世，火遍了大江南北，我也加入了大潮之中，我腾出了手机空间，下载了“共享单车ofo”的软件。原来上学需要走半个小时的路程，现在只需要骑车十分钟就可以到达，不过最让我倾心的还是它对环境的保护，原来被私家车挤满的街道，又成为了共享单车的天下，对环境的保护可是巨大的。而换一个角度，这款软件对我来说，还像是一款“约会软件”，有了它，我和小黄车们上学约会、放学约会，放假约会，出去玩也约会，这样的约会锻炼身体，保护环境，绝对不影响学习！
但是我在践行绿色出行的过程中，发现了问题，很多共享单车的序列号、二维码都被人破坏了，无法正常使用，而我自身也存在着问题。有一次，当我对着车打开软件时，我竟然发现它没有锁上，当时我免费起了一次车，但是越骑越不舒服，我是收获了方便，但同时也破坏了公平，所以我坚决杜绝了这样的行为再次发生。我也希望共享单车企业可以优化管理措施，督促市民自觉遵守规定。
在政府、企业、市民的多方面努力下，北京的空气质量有了明显好转，2016年均PM2.5浓度相比15年下降了百分之十二，相比13年下降了半分之三十。我相信，在越来越多的人的努力下，北京的环境会越来越好，让我们携起手来，共同投入到保护北京环境的行列之中，让我们能在美丽的城市之中呼吸新鲜的空气！
Sharing the green ride
Hello,every one ,I’m Liyunwei ,today ,my speech topic is “sharing the green ride”.
Starting with past winter ,every one my notice that the roads have been combed with so-called “little yellow ofo”easy rent bikes .The design of this bikes are cool,with two-dimension code,one can easily rent ,the most important,by bike sharing ,riders have fulfilled promise of “Green ride”.
Just by chance ,I become one of these shared riders.I find that the shared bikes are very convenient and helpful.Instead of driving cars or taking buses,a biker takes no emissions on the air to contribute smog,save times and actively does exercises. I used to spend 30 minutes walking to school,with a shared bike ,it only takes me 10minutes to get there.Mose importantly,I have done my deed to protect the small environment where the city I have lived in.
The published smog index shows that in Beijing,the concentration of PM2.5 has reached 1000milligram per cubic meter. This is a very serious problem! By breathing in the bad air,it could cause many kinds of diseases.”Green ride” is encouraged by the government.Premier Li has indicated it from his central government work report on March 5th,2017 that we shall fight and win “the war of defending our blue sky”.So every of us needs to do something to delay or stop the bad environment develop further.
Because of no supervision,it’a pity to see that numbers on the bikes are scratched and locks are damaged.Once I rode a bike without being properly unlocked ,and I paid nothing.I was happy at first .But know ,when ever I think about it ,I still fell flush.I think we live in Beijing,it is our duty to do as a Beijinger.
Now,the concept of “Green ride” is rooted in people’s lives gradually.I personally,hope the government and private sectors will invest more on the “green style of living”to make the environment cleaner and breath easier. For myself, I will do what I can, not only riding a bike ,but do more for our better living conditions.
Have you ever ridden an ofo?
Come and join us!
