Almost a seventh of China has been under heavy smog. The air pollution in 20 cities has reached the “danger level”. China is not alone, however. Many countries have the same situation. The air pollution is a problem from which we can't hide.
The United States
Since the beginning of the 19th century, America has had trouble with environmental problems, air pollution in particular. Almost 60 percent of Americans live in areas, where air pollution has reached unhealthy levels. It can make people sick.
The US created the Environmental Protection Agency in 1970 and passed the Clean Air Act. Now the air all over the country is much cleaner, especially compared to ten years ago.
London
Yellow?grey smog was a frequent visitor to London in the 1950s and got the name “London fog”. The heaviest, which shocked the world, was in 1952. Because of cold weather and windless conditions, polluted air covered the city. People could see something around them only in a few meters and about 4，000 people died. In 1956, London passed the Clean Air Act. It largely reduced air pollution.
New Delhi
Because New Delhi is developing fast, its air quality is even worse than that of Chinese cities. New Delhi has done little to improve air quality in recent years. However, the city government made a few changes more than 10 years ago. They moved industry out of the city, built a subway and improved public transport.

仁爱英语同步练习册系列答案Playing with friends, going to a party, having a meal in a restaurant or receiving a birthday gift—as a teenager, you go to different places and meet different kinds of people. Everything you do leaves an impression (印象). So manners are very important.
Arriving 30 minutes late for a date may say: “This isn’t that important to me.” Taking a cell phone call while talking to your friend may say: “The caller is more important than the person standing in front of me.” Failing to show thanks to a gift-giver may say: “I don’t like the gift.”
Is that the message you really want to send? Maybe not. You do not want to be rude, but sometimes what you do makes people think you’re impolite.
How can you change that? First, you should know the proper ways to behave around people. We call this manners. You could start by adding “please” and “thank you” to your vocabulary and avoiding bad language. You could start by holding a door open for someone after you to go through. You could start by showing up on time instead of letting others wait for you.
Start now! Start a new life and start to be a teenager with good manners!
