    Recently I have started a new job in a small office, which four of us share a water filter(净水器). One of my coworker complained the water tasted "dirty", and she is astonished I could drink the water with any trouble. I even started to doubt my taste buds, but the water really tastes fine. Finally, she figured out the problem was actually my cup, which she simply forgot to clean.

    I can't help but to think about the world we live. Too often we quickly blame other people, other things, something else but ourselves. The world isn't perfect, I know, but I think we should take the step back sometimes and ask ourselves some tough questions. Can I be better? Is my heart really pure? …

    Please clean your cup. Because when you do, the water will taste much good. I promise you this.

    It has been a long time since I did anything good for the environment. Feeling responsible to protect the environment, I decided to take the action again. I told my idea to my friends and we planned to plant tree on the hill in the countryside. We came to the foot of the hill and selected a place where looked suitably and settled down. We spend a few hours digging holes and placing the young seedlings. Then we wrote our wishes on cards one to one and buried it deep down the roots of the trees. We also took a lot of pictures. We were such busy that we didn't realize that it was time to go back. I felt really glad that we made difference to the environment.

    I am writing this letter to thank you for guidance you gave me. I was a perfectly stranger when reaching this city. Once lost myself in a downtown street, I stopped to ask some people for help. As you know, this is the first time for us to come up to this big city.

    I bought a guidebook, and I still had difficulties in going around the city. The streets and shops puzzled me too much that I would rather stay indoors. It is your valuable guidance which has enabled me go about the city without any trouble. Now I begin to know how to take proper buses. Yesterday I went downtown with some of my schoolmates for shopping.

    Lessons will begin after a few days. I will come over to sec you some day next week and tell you everything that has happened to me.

    Do you believe love is the most important? In the early twenty century, homeless people were often brought up in orphanages, in that they received little love. At one time, Dr. Skeels took twelve children from art orphanage or had a young girl look them each day. He also studied another twelve children who are left in the orphanage all day long. He followed these children not until I hey grew up, and the results were shocked. The children staying all day in the orphanage were either dead or suffering from serious illnesses.

Dear editor，

    I'm sorry to occupy your precious time, and I really want to tell you anything about the problem of some people keeping too many pets nowadays. I take the problem more and more seriously for the following reason. First of all, as it is known to people, pets make loud noise that trouble residents a lot. What's more, it is widely accepted that animal waste pollutes the environment, where makes people quite uncomfortable. Many owners like taking their pets to public place where they may frighten children or even bite people. The mostly important is that pets can spread some diseases and this has attracted much attention. Take all these factors into consideration, I sincerely hope that I can get help from you and expect the media do something for this.
