My mother only had one eye. I hated her, as she was such an embarrassment (难堪）for me. She ran a small shop at a market, selling anything for the money we needed.

    One day, my mom came to my school. I threw her a hateful look and ran out. The next day, my classmates shouted, “Your mom only has one eye!" and they taunted me. My face turned red.

I wished that my mom would just disappear from this world, so I said to her, “Mom, why don't you have the other eye? You make me a laughingstock.” She didn't say anything. Maybe it was because my mom hadn't punished me, so I didn't think that I had hurt her feelings very badly. I decided to study hard so that I could leave her for the rest of my life. I made it at last. Now I'm living happily as a successful man in another country.

Many years later, I received a letter, which said, “I think my life has been long enough now， but would it be too much to ask if I wanted you to visit me once in a while? I'm sorry that I am an embarrassment for you. You see, when you were very young, you got into an accident, and lost your eye. As a mother, I couldn't stand watching you having to grow up with only one eye, so I gave you mine. I was so proud of my son that was seeing a whole new world for me, in my place, with that eye. I was never angry with you for anything you did. I miss the time when you were still young around me. You mean the world to me. I love you.” I can't help crying with the letter in my hand.

    I stood there listening to my father shout at top of his voice. The look on his face said that one of us had done something wrong.

    “Which one of you did this?”

    We all looked down at the step. There was child's handwriting in chalk there. I was very frightened. I hope no one could see it. Would he guess it was me? I was so scared. When he asked me, I lied, “Not me, dad.” The other denied(否认) it as well. Of course, we all knew that one of us must have done it. But as the youngest and smallest of the three, I just couldn't find courage to tell the truth.

    To find out who had written on the step, Father gave us each a piece of paper and a pencil. “I want each of you to write exactly what you see on the step.” I tried my best to write the words differently. I didn't want dad to be able to tell it was me.

    He gathered up our paper and looked at them. “Since none of you will say yes, then I will punish you all.” I stood there and said nothing. The last thing I wanted was for Dad to punish me!

    “I did it.” My sister walked forward and said she had done something she hadn't. She was punished for a month.

   We didn't talk about that day for many years. Not until we were all older and I knew it was safe to finally tell my dad it was really me. I always felt sorry because of it. That was the last time I let anyone take the blame for me. I told myself, “One must see to what he or she has done.”

Many social media posts(社交媒体帖子) may let you believe that everyone is happy all the time, but being happy all the time is not possible.

As a teenager, you probably expected to get good grades in an exam or to win the most important basketball game, but it didn't happen. Good results make you happy and bad results make you sad. But sadness can drive you to improve yourself next time.

However, when people get into sadness for a long time and it starts to affect(影响) their lives, it's called depression (抑郁). You don't want to get out of bed. You don't feel like studýing or going out with your friends. I remember the same feeling when my dog Rebel died in an accident. I remember that he followed me to school. Now he was gone, and I lost all interests to do anything.

My parents told me dogs don't live forever. What was more, Rebel had a good life. If Ihad a good life, Rebel must be happy, too.

Depression is not a person's mistake. It's normal to feel sad sometimes. Many great people, like the comedy actor Jim Carrey, once get depressed. But you should know what to do to stop depression or make yourself less depressed.

When you feel down, you must not keep yourself away from the world. Try to share your feelings with a family member or a good friend. Staying at home by yourself will make you more lonely. You should stand up, open the window, and throw away (抛弃) the sadness.

Recently, researchers have found that dolphins know their own names much like people. Dolphins talk to one another with whistles (口哨) and calls. Scientists have known that the animals also use unusual whistles to name each other. They had thought that dolphins only heard each other's voices. However, the scientists didn't know that dolphins listen for their names too.

To test this idea, the researchers caught 14 dolphins and recorded their name calls. The scientists then copied each dolphin's voice. When the changed recordings were played, the dolphins replied strongly to the names of their relatives and group members. They paid no attention to the names of dolphins they did not know.

Dolphins live in large groups that grow and change. Each dolphin's unusual whistle helps it quickly find a friend or a family member, or call for help. Understanding their calls requires learning. It's a skill that's seen in very few animals, which include humans and elephants.

Elephants, for example, communicate with sound. Their sounds can be heard by other elephants miles away. Dolphins, too, communicate with each other by making sounds like this. Elephants also communicate by moving their head, feet and trunk (象鼻). In much the same way, dolphins communicate by their movements. They often touch each other to express friendship.

Unlike dolphins, elephants also communicate by their great sense of smell. They can recognize other elephants by the smells they have.

Why do dolphins and elephants share the gift of communication? Scientists think it may be because they are social and smart animals. Both have strong family relationship. Now, whether they also have nicknames(绰号) is another question!

Do you like traveling? If you don't know where to go on vacation,here are some great places for you to choose(选择) from.

Do you know the small town Wuzhen? It has a history of over 1,300 years with around 87,000 people living there. And it is a beautiful place with many travelers. If you travel there for the first time,you may get lost because there are lots of rivers and bridges in the water town.

Hailing Island is the second place I want to talk about.It is a wonderful place for a relaxing holiday. The beaches there are so great. There are not so many people there,so you can live quietly and comfortably there.

Chongqing is a place that many people like to visit. It has a history of over 3,000 years. It is a city surrounded  by mountains.You  can  see  mountains  everywhere around the city. And this city is also famous(出名的) for its tasty food.
