I remember when I was growing up ,my mom always said ,“Half the fun of doing anything is sharing it with others .” It's so true .Friends allow us to enjoy the taste of our success and our joys and comfort us in our challenging moments. They provide a mirror for us to learn more about ourselves .I've always looked at friends as the family members.They enrich our lives .As Robert Louis Steven once said,"A friend is a present which you give yourself."

To be a good friend，①成为一个好的听众是很重要的.Hear what your friend says first rather than making conclusions（结论）quickly. Sometimes it is useful to repeated their words back to them， it can help them to realize whether their words were what they wanted to say.

Patience is also important in being a good friend. You know the old golden rule, “Care for others they way you would like them to care for you.”The support of a friend during a difficult time could make the difference between success and failure. ② Encouragement and confidence are the best gifts that can change a person's life.

We should choose our friends carefully, because they can have a huge effect on our life. As someone told me“The attitudes of your friends are like the button(按钮) on a lift. They will either take you up or down.

    However, there are some dangers of WeChat. It is often reported that many traffic accidents are caused by careless drivers who can't help playing on WeChat while driving. And some bad guys even use WeChat to gamble(赌博), which breaks the law. Luckily, WeChat is improved now and then.

   Eileen Collins is the first woman ever chosen to be a spaceship pilot. She is also the first woman to be a leader in a spaceship. Today she has flown for more than 5,000 hours in more than 30 kinds of airplanes.

   Talking about high school, she said, "I began reading all kinds of books about famous women pilots. These women went and flew into dangerous places. Their stories encouraged me." In 1977 Eileen got a pilot's license (证件) and the following year she finished her university. She went into space in 1999 at the age of 43. She took the hopes with her and dreams of a nation of young people on the earth.

   Eileen is not only an astronaut, but also a wife and the mother of a young daughter. She has short curly hair and friendly brown eyes. She met her husband, Pat, while they were together in the air force (空军).

   When she was named as the First Woman Spaceship Commander (指挥官) in 1998, Eileen smiled and said, "When I was a child, I dreamed about space. It was only a dream that I would be one of the astronauts some day. I hope all children will be encouraged to reach for their dreams, when they see I go into space. I believe dreams do come true!"

    What can we do to help protect the environment? It seems useless to just pick up a piece of trash(垃圾) ,but what will happen if you keep doing it every day? Tommy Kleyn, an ordinary man from the Netherlands, may give you the answer. Tommy Kieyn walked past a polluted river on his way to work every day. It used to be a beautiful view, but the trash on the bank made it dirty and smelly. So Tommy decided to pick up the trash along the river a little bit at a time after work. "It took me about 30 minutes to fill one garbage(垃圾) bag with trash, but one garbage bag didn't seem helpful in a place as polluted as this. I decided to fill one bag of trash each day as I passed by," Tommy said. Every day, Tommy took pictures of the river and shared them on his Facebook page. To his surprise, in just six days, he had made great progress with his cleanup effort(努力) . He felt happy and kept doing it. Gradually, more and more people knew about Tommy's story. Other people in the community began following in his footsteps and cleaning up trash on their way home, too. "The idea is to encourage people to fill one garbage bag with litter each day. It only takes 30 minutes, but it really makes a difference and you will be amazed at how good you feel afterwards, "he said. People from all over the world have been moved and inspired(激励)by Tommy's story. No effort is useless if we keep doing it every day. Ordinary people like you and me can also make a difference to the world we live in if we take actions right now.
