Why don’t birds get lost on their long flights (飞行) from one place to another? Scientists have studied this puzzle for a long time. Now they’re starting to fill in the blanks(空白).

Not long ago, experiments showed that birds use the sun to guide them during daylight hours. How do birds fly at night? Tests with artificial stars, which are made by people, have proved that certain night-flying birds are able to follow the stars in their long-distance flights.

They found a bird that spent its lifetime in a cage and never flew under a natural sky. But it was born with the ability to use the stars to look for the direction. This bird’s cage was placed under the sky filled with artificial stars. Any change in the position of the artificial stars caused a change in the direction of the bird’s flight. From the experiment, they found that the bird tried to fly in the same direction as those artificial stars moving under the natural sky.

But the stars are of course birds’ main ways of navigation (航行), when the stars are hidden by clouds, they can still find their way by such landmarks (路标) as river courses, mountain ranges (山脉), coast lines and so on. Because of this ability, people use the dove (鸽子) to send messages in some fields. For example, the doves were used to send messages in both World War I and World War II. During that time, thousands of doves were used to carry important messages in order to save the lives of many thousands of people. So it is also the symbol of peace.

But when it’s too dark to see these things, the doves are not able to find their way. They only circle helplessly and get lost.

When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect(尊敬) elders. Unluckily, this rule led to my very first embarrassment in the United States.

I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive(敏感) Americans are and how they dislike the description(描述) “old”. I then walked back to the table and apologized（道歉）to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.

In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.

However, in the United States, people think “growing old” is a problem since “old” shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises or jogging, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn’t want to hear.

After that, I changed the way I had been with older people. It is not that I don’t respect them any more; I still respect them, but now I don’t show my feelings through words.

Today there are many more fires than in the past. Over 100 000 wildfires burn each year in America. Russia has 20 000 to 35 000 wildfires every year. Australia has on average 60 000 each year. These fires destroy(损害) huge areas of forests and burn hundreds of homes.

Many experts believe there are several reasons for this sudden increase in fires. The first reason is climate(气候)change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightning strikes(发生雷击), dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2 000 homes. Some people lost their lives.

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fires. They didn’t allow the grass and trees to burn. As a result, today many forests have thicker vegetation(植被). Thicker vegetation means more fuel for fires. Also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of a healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, firefighters even start fires to get rid of dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat to people, firefighters may let it burn naturally.

1.Why did Russia have so many fires in one month in 2010?

A. Because lighting spread a fire.

B. Because there was much fuel for fires.

C. Because there were not enough firefighters.

D. Because it was unusually hot, dry and windy.

2. What is the main idea of paragraph 4?

A. Fires are serious threats to human beings.

B. Fires can play an important role in forests.

C. Australian firefighters don’t put out fires.

D. It’s difficult for firefighters to control the fires.
