5．Scientists have helped people understand the dangers facing the earth．As people live on the earth，we should be fully ready to deal with the dangers．If we do not pay more attention to the problems caused by air pollution，our earth may no longer be a healthy place for plants，animals，and people to live．
Cleaning up the air is a job that all countries must work on．The problems caused by air pollution can be solved，but a lot of work needs to be done．Governments around the world are beginning to work together to lower the levels of dangerous gases in the atmosphere（大氣層）．If this can be done well，the ozone layer（臭氧層） can rebuild itself，global warming can be controlled，and acid rain can be reduced．
In 1967，the government of the United States passed the Clean Air Act．More parts were added to the act in 1970，1977and 1990．As a result of these laws，cars now must reduce the amounts of harmful gases．Power factories must use"clean coal"methods to reduce acid-rain gases they produce．
In 1970，the Environmental Protection Agency （EPA） was set up．The EPA's job is to make sure that the environmental laws are being followed and to find out new dangers and offer solutions．The first Earth Day was also celebrated in 1970．
While it is very important to address with air on a global scale，each person can also do something to protect the Earth．Here are some things you can do every day：
1）Turn down the heat and air conditioning．
2）Use the dishwasher only when they are full of dishes．
3）Practice the 3Rs：recycle，reuse，and reduce．
4）Plant a tree．
5）Walk or ride your bike．

76．If we don't care aboutA problems，our earth may no longer be a healthy place．
A．Air pollution
B．Water pollution 
C．Noise pollution
77．Every country shouldB to solve the problems caused by air pollution．
A．rebuild the ozone layer
B．clean up the air      
C．produce harmful gases
78．All the things the EPA can do is toC
A．make more laws  
B．find out new dangers
C．protect the environment
79．The Clean Air Act was passedA by the American government．
A．In 1967      
B．In 1970
C．In 1977
80．In our daily life，we can do something to protect the earth byB．
A．using more cars  
B．riding the bikes       
C．cutting down trees．
