Have you ever complained that life is so tiring or that there is too much homework? Does the sky sometimes seem dark to you? Are your studies sometimes not successful? Well, friends, cheer up and smile all the time. If you look at the world with a warm heart, you will find that the whole world smiles at you.
While in school, sometimes you are tired of your lessons, but have you noticed the happy smile on your teacher’s face when you do a good job?
If one day it is fine, but just before you go out, it suddenly starts to rain. Maybe you would feel very sad and start complaining about the weather. Dear friends, why don’t you sit down and listen to the free concert that the nature offers you? Also with the timely rain, crops in the fields will grow better and better and farmers will have a good harvest.
Although everyone wants to succeed in what he tries to do, sometimes failure can’t be avoided. I think failure is not terrible. The terrible thing is that we are afraid of it and give up hope. When we face failure, we must be confident of ourselves, draw a useful lesson from it and try our best to finish what we have decided to do. As a popular saying goes, “Failure is the mother of the success.”
Attitude decides everything, with an optimistic attitude life is easy and pleasant. Let’s smile at whatever we meet and the whole world will smiles at us.

【小题1】Students sometimes complain _____________.

Have you heard of Chen Binqiang in Zhejiang Province? Over the past six years, he has taken care of his mother who got Alzheimer’s disease.
Chen’s mother, 64-year-old Chen Yueguang, has been ill since 2007. The illness became very serious quickly and she has lost the ability to speak and can not look after herself. None of Chen’s other family members, however, could take care of their sick mother. Chen’s father died in a traffic accident when he was eight, his two sisters married far away and his wife has a 92-year-old grandmother to look after. 
Chen taught Chinese in Central School of Lengshui town, which is about 30 kilometers away from his home in Pan’an. So he spent five days at school and only went home on weekends. When he said he would take his mother to work, even his wife was doubtful and worried. She really doesn’t think it is a good idea for him to take care of his mother in school. She worries what if he lost his job because of this.
But Chen has made the decision. Soon he was putting a safety hat onto his mother’s head and helping her sit on his electric bike’s back seat. He thinks that his mother used to take him around and now he should take her.
These days, things got a little easier for him. With the help of Pan’an government, Chen got a new job in Pan’an Middle School in October 2012. The new school is only five minutes’ ride from his home, which means he can take care of his mother more conveniently.
Chen feels happiest when his mother is looking at him. She must have forgotten who he is, and she even can’t call his name. But she surely knows that Chen is kind to her. He feels that is enough.
On February 19^th, 2013, Chen got the prize for Touching China, held by China Central Television to honor those whose performances have moved the people.
