Sweeping city skies
We always check the weather before a trip. But after hearing a lot about air pollution .we often wonder: h 66 will the air be tomorrow?
On Sept 1, Forecasting air pollution started to be on TV. There are six grades, with the first grade meaning excellent air.
The forecast helps us plan trips, and helps the government make plans to stop air p 67 . China is making an e 68 to clean the air.
Big cities such as Beijing and Shanghai are taking the air pollution seriously first.
On Sept 2, Beijing said it will reduce PM2.5 density (密度) by at l 69 25 percent by 2017. How will the city make it come t 70 ?
Car emissions (排放物) is one of the main c 71 of PM2.5 in big cities, so fewer cars will be in Beijing next year. It is also asking for congestion fees (拥堵费) from car driving in the city center.
There’s a lot of PM2.5 in waste gas(废气)from factories. Beijing will close some companies. If a company pollutes h 72 , it will have to buy water and electricity at a h 73 price. In order to have more blue s 74 , every one of us should also help.
We can help by taking buses i 75 of cars or taxies. We can also help by giving up smoking.
So from now on, take action and do your part.
