题目：二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。

Air pollution

People and air pollution are often in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major kind of air pollution is the gas from cars. Statistics (统计资料) show that 93 percent of all auto trips are within cities.

Another major kind of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country.

On the average, we throw away more rubbish than the year before. The burning of rubbish makes air pollution even worse. Many major industries are also responsible for the dirty air in the around cities. The fumes (烟) from iron, steel, chemical, and petrol production add particles (微粒)  to the air.

The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode (腐蚀). In some of the larger cities, these fumes endanger the lives of human beings by contributing to lung diseases and causing early death.

1. The key point of the passage is that {A; B; C}.

A．the cause of air pollution is people

B．the causes and the effects of air pollution are both found in cities

C．the effects of air pollution range from headaches to death

2. What is the purpose of this passage? {A; B; C}

A．to persuade people to stop polluting the air

B．to tell the causes of air pollution

C．to tell why cities are bad places to live

3. Why is air pollution more grave in the city than in the country? {A; B; C}

A．Because there are larger populations in cities.

B．Because the air in the city is dirty.

C．Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country.

4. The fumes from coal and oil may cause metal {A; B; C}.

A．to corrode            B．to twist               C．to turn black

5. In larger cities, the fumes from coal and oil may contribute to {A; B; C}.

A．heart disease        B．loss of clear vision           C．lung diseases

题目：二、阅读理解：阅读下面短文，选择合适的内容将短文补充完整。

A. to cook or heat your home

B. checked regularly

C. to reduce air pollution

D. Use less electricity

E. Raising any sort of livestock

Man-made air pollution mainly comes from two sources: mobile ones and stationary ones. Mobile sources are cars, planes, boats, etc. Stationary sources include large factories, power plants and every household, which burns natural gas or wood. The most important ways _____ are to drive less, use less electricity and natural gas, and eat vegetarian.

_THESE IDEAS ARE EASY TO FOLLOW:_

1. Get your car _____ to make sure everything works properly. Whenever possible, walk, cycle, carpool, or use public transportation. Buy fuel-efficient vehicles. Drive at 60 mph or less to improve gas mileage.

2. Burn less natural gas _____ . Instead, use a solar cooker or heater and wear extra layers.

3. Become a vegetarian or a vegan. _____ requires more land and emits more carbon dioxide than simply growing crops directly for human food.

4. _____. Coal power plants produce most of the world’s electricity, and they also produce more carbon dioxide than any other source. Coal plants also release many other pollutants. Unplug televisions, cell phone chargers, and other appliances while not in use. Most devices continue to use small amounts of power even when they’re turned off. Avoid using air conditioning, and don’t leave the fridge open any longer than necessary. Only run the clothes washer or dish washer when full. Rather than using a dryer, hang clothes on a line to dry in the sun.
