Could a grizzly bear move to your neighborhood? If you live in the U.S. West, the answer may be yes. People and grizzly bears are living closer together now.

The grizzly bear is one of the largest meat-eating land animals in North America. In the early 1800s, about 50,000 grizzly bears lived there. Today there’re far fewer bears. Settlers built cities and roads where bears lived. Many bears were hunted and killed. Now only 1,200 to 1,400 grizzly bears have remained.

In and around Yellowstone National Park, grizzly bears have been making a comeback because of people’s efforts to protect them. Some bears are moving to areas where people live. People are also moving into grizzly countries.

People there have to learn how to live with their new, furry (毛皮的) neighbors peacefully. If someone leaves their barbecue grill（烤肉架）out overnight, or leaves their pet food or rubbish where a bear can get it, the bear will learn to come to their house for food. Grizzly bears that learn to eat people’s food can become dangerous, and they often have to be killed or moved. Also, it’s important not to surprise a grizzly. Besides, if you are hiking in a grizzly country, you should go with others and make a noise to make bears hear your coming and get out of the way. You may not want to invite grizzly bears to your next neighborhood party, but with a little effort, grizzly bears and people can live together peacefully.

Why does the number of grizzly bears get smaller, according to the text?

A. Settlers’ buildings break the balance of their living environment.  

B. Land for them to live on is limited and they are hunted in large numbers.

C. Yellowstone National Park wants to control the number of them.

Too many cars have created a lot of serious problems in our world. Besides congestion(拥塞), accidents and fast fuel consumption(消费), cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. Last winter, car fumes(烟雾) formed heavy smog over Beijing, making the sky gloomy for weeks and deteriorating people's health.
One possible solution is to design and develop clean cars and clean fuels. In Tsinghua University, campus buses are driven by electricity. In Beijing some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to completely replace the traditional ones.
Another solution is to develop modern public transportation systems and restrict （限制）the use of private cars. If the price of petrol rises constantly and the public vehicles（交通车辆） are efficient and convenient enough, most people will not use private cars. And the total number of cars in big cities will reduce greatly. 　　
On the whole, the elimination （根除）of air pollution needs the co-efforts from the government, the public and the environments. This problem will be solved only with the help of science and technology.
