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 Care and Keeping of Friends”by American author 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(耐心)．For example，if you have a bad day, a good friend should listen to your complains(抱怨)and do their best to help．To make a friend，you cannot be too shy．You should make each other happy and share your lives．

    But things cannot always be happy．Even the best friends have fights．What should you do when you have a fight with your friend? You have to talk to them．When there is no one around，have an honest talk．If he or she doesn’t want to talk，you could write a letter． 

Sally says there are three steps to being friends again：Toll him or her how you are feeling；say what your friend has done wrong，and explain why you did this or that．The book also has advice on some small but important things like celebrating your friends’ success．Even if you haven’t had a real friend before, you will start to think of having one if you read this book．Because the book tells that friendship is the most important thing in your life．

　　Then by chance, Darwin read a book by Malthus, an Englishman. The book was forty years old, and Malthus was already dead. But it suddenly pushed Darwin nearer to some answers. Malthus said,“The number of people in the world can grow very quickly. Just think, a man and his wife could have ten children. When these ten grow up, every one of them could have ten more children. So now we have a hundred children. Again, if every one of these has ten children, we will have a thousand children and this can continue. We will have more and more people.”

　　All this could happen. But did it? Malthus said,“No. It doesn't happen in the real world. The number of people remains almost the same. Why? The reason is this. We just can't grow food quickly enough. Soon there's not enough food. So some people can't eat. They die before they bring any more children into the world.”

　　These ideas came at just the right time for Darwin. He asked one more question: Which people will die before they have children? For Malthus, this was not an important question. But for Darwin, it was very important.

　　He asked,“Which people will have children? Why does this man have children, and why does that man not have any?”And soon of course he was thinking of the Galapagos finches（鸣鸟）again.

　　“The number of finches remains almost the same. So usually two birds must give us only two new birds. But a finch lays more than two eggs. Which two young birds will live, and give us more eggs? Which will not?”

　　The answer is some birds can't get enough food--they will die. But why can't they get enough? Why are some birds better than them? The birds in one family are not quite the same. Some are stronger, some are quicker, some are bigger, some have longer beaks, some have lighter bodies. The best birds will live.

　　And always an answer brought with a question: What is“best”? Darwin now, had his list of facts and questions, answers and ideas. Could he put them together and make a clear story? Could he explain the evolution（进化）of the finches?

　　He could and he did.
