Noise pollution is doing much harm to our health now. Noise，in fact，is unwanted sound and is a kind of invisible (无形的) killer. More and more students enjoy listening to music very much. When they listen to MP3 players, they like to turn up the volume (音量)．Some people love listening to loud music. Furthermore, while watching TV, they keep the volume up. But they haven't realized that the noise is weakening their hearing. In fact, the noise not only influences each member in the family, but also makes a difference to the comfort of neighbors.
Noise pollution is a source of increasing misery (痛苦) to people in our society. If people are often disturbed by it, they may feel uncomfortable or upset. What's worse, the noise can make people mad sometimes. If a worker works in a printing factory for too long, his/her hearing loss is much faster than a common person working in a quieter environment. So everybody must pay more attention to noise pollution. Generally speaking，the following four types of noise should be watched out for：
◆Noise in the street
◆Construction site (建筑工地) noise
◆Noise at work
◆Transportation noise
I think the local department (部门) should take measures to control the noise levels, but it's everybody's duty to keep a quiet environment.

Smog is one of the hot subjects these years. It does great harm to people's health. The most terrible smog lasted for about a week in February, 2014. It covered 15 percent of the land in northern and central China. Now, more and more people in China have realized the importance of protecting the environment. They try to save energy by walking or riding to work in their daily life. Cities including Beijing and Shanghai have taken action by controlling the number of cars and closing heavily polluting factories.
Beijing is heavily polluted, so it's not easy to see blue skies there. But during the APEC Summit (亚太经合会议峰会）in November last year, Beijing saw blue skies for a few days.

The two large countries, China and the USA, produce about 45 percent of the world's greenhouse gasses. On November 12, Presidents Xi Jinping and Obama announced that both countries would work together to cut down CO2 emissions（二氧化碳的排放）.The goal needs everyone's effort.
