Do you think there is a ghost(鬼) in the world? More than 20 years ago, a student jumped from the top of the clock tower in the University of Birmingham. He did this only because he failed his final exam.

   After his death, a superstition(迷信)began: Anyone who walks under the clock tower will have bad luck in his exam. Years later, students there still remembered the story of the tower. Although Birmingham is the second largest city in Britain, the university is green and quiet. The grass around the tower has been worn away by the feet of students who refuse to pass underneath the tower.

   The university had to pave(铺)extra paths, so students could walk to their classrooms without passing under the most terrible area. But, one day just before an important exam, a top student in the university walked under the clock tower because he was lost in thought.

However, he got high marks in the exam the next day. Quickly students all knew about it. Then they realized that the most important thing is working hard. 

   Whenever I go under the clock tower, I will tell myself, “Working hard is the key to success.”

    Confidence is very important in daily life. It can help you to develop a healthy attitude (态度). A study shows that the people who are more confident are much happier. They can have more chances to make themselves successful. The following is about how to be more confident.

    Speak loud.  When you are not confident, you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.

    Play sports.  Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.

    Encourage yourself.  To see how many things you have done well, you can write down a list of things you did during the day. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you've done.

    Pick up a hobby.   If you like singing, sing as much as you can. In some ways, a hobby can make you outstanding. And it will make you happy and confident.

    Get rid of (消除) fear. Fear comes along with failure (失败). But it's easy to overcome (克服) if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

    Because of Disney's film Finding Nemo, the clownfish (小丑鱼) are facing the danger of dying out. The film received positive reviews and won the Acaden Award for Best Animated Feature. It was a success as it earned over $864 million worldwide.

    Finding Nemo is about a clownfish who tried to save his son who has been caught by a man from becoming a pet. One thing we can learn from the film is that wild animals really have to remain in their habitats(栖息地). However, the message seems not to be stuck in the minds of children. The clownfish are facing the danger of dying out several years after the animated film was on, because the film itself made them the must — have pets for kids all over the world!

    It is said that just half of needs can be met by clownfish bred in captivity(人工饲养)，which means the rest have to be taken from the sea. Now the average(平均的) size of clownfish schools (鱼群) in Australia, has decreased from twenty-five members to just six, making it harder for them to breed. Dr Billy Sinclair who has spent five years studying the clownfish was the first to raise the alarm, “The film did much to educate children about sea life but the fish were then sold as children's pets. My message to kids who loved the film is simple: Tell your parents to leave Nemo in the sea where it belongs.”

    Harbin Opera House (哈尔滨大剧院) lies on Harbin Cultural Island, near the Songhua River. It took people about six years to complete the whole project and it opened in 2015. Its building style belongs to a future time. With the size of 7,900m², it is considered as the performing arts centre in Harbin, Heilongjiang Province. Its special surface allows more light to enter. Its two theaters, the large theatre and the small one, can hold about 2,000 people. The project is a complete success. Harbin Opera House has enjoyed many prizes and great fame from home and abroad since people began to plan it. People say it's one of the most beautiful buildings in China and it is the world's best concert halls. There is no doubt that it has become the new symbol of Harbin.
