A young man called Low-Carbon Brother become a hit on the Internet in 2011. He suggests living a low-carbon life, which means using less energy in our daily life so that we can help reducing carbon dioxide in the air. For example, she always picks up some waste paper on the street or uses the blank side to write something. While he is watching TV, he always turns up the screen brightness to the minimum and turns off the light. Therefore, he goes to work by bike instead of driving. Some people think what he is doing is just a show. No one can live such a simply life with so many modern invention around us. As far as I am concerned, I am strongly in support his idea and his behavior. Although what he is doing has no huge effect on global warming, but he at least can enjoy a healthy life.

Dear Editor,
Recently, my classmates have had a heated discussion about that
we should have optional courses in high schools. Some students were
in favor of optional courses. They say interest is best teacher
and our spare time will be colorful and meaningful. Students
can not only enlarge their knowledges but also improve their abilities.
However, others are against the idea, said that optional courses
will take up too much time as well as energy. In addition to, some optional
courses have something to do with the College Entrance Examination. They
are afraid they’ll fall behind their classmates if they will take the
optional courses. I’d like to take one or two of the optional courses, which, I think, will certain benefit me a lot.
Yours truly,
Li Hua

There was a lot of passengers on a city bus. When the bus arrived at a stop, the pretty woman got on the bus. All the passengers kept their eyes fixing on her. An old man near the door attempted to get up, and the woman forced him back into her seat. “Thank you, but please sit down,” she said. “But, madam…” replies the man. “You really needn’t to do that since I’m young,” interrupted the woman. Later, the man tried to rise again but stopped by the woman. Finally the man managed to rise and said angry, “The bus has carried me three blocks beyond my house. I have to get on.”
