    Canada Geese are large blue and white birds. When autumn comes, they have to fly south where the weather is warmer. The winters are so cold in Canada that the birds will die if they stay there.

    Last spring, Bill Lishman found sixteen young Canada Geese on his farm. They had lost their parents. Bill thought, “These young birds won't know what to do in the autumn.” He had a small plane and he decided to teach the birds to fly by following him. All through the summer, he went on short trips in his plane and the young geese flew after him.

    When the cold weather arrived in the autumn, Bill flew to Virginia in the United States--600 miles south of his home in Canada. The geese followed him all the way. Bill left the geese in Virginia and he returned home. This spring, Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia to get them. He looked for them for two weeks but he couldn't find them. When he arrived back home, he found the geese waiting for him. They had found their way home without him!

    Once there was a boy and his little sister living in a small village. The boy was good—looking but his sister was not. One day they found a mirror(镜子)and they saw what they looked like for the first time. The boy was very pleased and he said to his sister, "How handsome I am! I look nicer than you!" The girl didn't like what her brother said and gave him a hard push. "Go away!" she said angrily.

    Their father saw what was happening, He went up to them and said to the boy, "You must always be good as well as look good." Then the father said to the girl, "My dear, if you help everyone and do your best to please(使愉快)them, everyone will love you. It doesn't matter that you are not as good— looking as your brother. "

①Everybody enjoys acts of kindness (善.举). But can you explain why? Some people think kindness is something out of love and care, while others believe it is just a tool to make us more popular. But research shows that being kind can activate (激活) an area of the brain called Striatum. Research also shows that kindness improves people's moods(情绪). But why and how does it happen? Here are a number of different ways.

②Firstly, being kind can make someone smile. If you see yourself smile in a situation, people around may be smiling too, especially for your close friends and family. A kind act makes someone who is sad feel better. It can also make ourselves feel good.

③Secondly, being kind starts or develops a social connection with others. Kind acts like buying someone a present make friendships stronger. Research has shown that spending money on others may help you get a stronger feeling of happiness than spending it on yourself.

④ Thirdly, in another research, even children in their first year of secondary school know how being kind makes them feel happy. If one person is kind, he or she makes others in the group kind. It also lifts everyone's spirits.

⑤Lastly, the story doesn't end here. Being kind may improve your mood, but research has also shown that if you're in a good mood, you can act much more kindly. This makes it a wonderful two-way relationship, doesn't it?
