Everyone needs friends. There is an old saying “Friends are God's way of taking care of us.” But how do you find real friendship and keep it?

The American writer Sally Seamans tells young students some smart ways to find friends. Sally says finding friendship is just like planting a tree. You plant the seed and take care of it to make it grow.

First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend should listen to your complaints and do his or her best to help. To make a friend, you can not be too shy. You should make each other happy and share your lives. But things cannot always be happy. Even the best have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have an honest talk. If he or she doesn't want to talk, you could write a letter.

There are three steps to being friends again:

Tell him or her how you are feeling ; say what your friend has done wrong, and explain why you did this or that. Remember that friendship is the most important thing in your life.

单项选择题

The fact that most Americans live in urban areas does not mean that they reside in the center of large cities. In fact, more Americans live in the suburbs of large metropolitan areas than in the cities themselves.
The Bureau of the Census regards any area with more than 2,500 people as an urban area, and does not consider boundaries of cities and suburbs.
According to the Bureau, the political boundaries are less significant than the social and economic relationships and the transportation and communication systems that integrate a locale. The term used by the Bureau for an integrated metropolis is an MSA, which stands for Metropolitan Statistical Area. In general, an MSA is any area that contains a city and its surrounding suburbs and has a total population of 50,000 or more.
At the present time, the Bureau reports more than 280 MSAs, which together account for 75 percent of the U.S. population. In addition, the Bureau recognizes 18 megapolises, that is, continuous adjacent metropolitan areas. One of the most obvious megapolises includes a chain of hundreds of cities and suburbs across 10 states on the East Coast from Massachusetts to Virginia, including Boston, New York, and Washington D. C. In the Eastern Corridor, as it is called, a population of 45 million inhabitants is concentrated. Another megapolis that is growing rapidly is the California coast from San Francisco through Los Angeles to San Diego.

Why does the author mention the Eastern Corridor and the California coast in Paragraph 4

A.As examples of megapolises.

B.Because 75 percent of the population lives there.

C.To conclude the passage.

D.The Bureau of the Census is located ther
