And why more leaves are green in colour?The answer is that plants need these green leaves to make food.A plant needs sunlight and carbon dioxide（二氧化碳）from the air for making food.The plant also needs water and salt from the soil to make food.There are certain cells in the leaves which change carbon dioxide and water into sugar To do this the cells（细胞） need energy.They get this energy from sunlight.At night when there is no Sun,the Leaves don’t make food.Green leaves make food for the whole plant.A red leaf can make food too because under the red colouring of the leaf are food making cells.There are no leaves which are completely yellow.Yellow leaves can not make food.The plant makes sugar for its food.In sunlight green leaves make a lot of sugar.The veins（叶脉）can not carry all this sugar away,So the leaves change the sugar into starch（淀粉）This starch is kept and stored in the leaves.At night,when the sun is not shining.The starch changes back to sugar.It is then carried away from the leaves.Some of the sugar is used as food by the plant while the rest is stored as starch in the plant.In some plants,food is stored in the roots.In others it is stored in the stem（树干）and in leaves,fruits and seeds  PEKING Opera used to sound strange to Dou Yi.The l4-year-old Beijinger said whenever she came across Peking Opera on TV,she changed the channel.Like most of today’s teenagers,Dou loves pop music.　　But since Dou entered the Xuanwu branch school of Beijing No.15 Middle School.she has been studying Peking Opera in music class every week.　　Dou and her classmates listen to Peking Opera and learn the basics（基础知识）from professional actors.They also sing along with the operas.　　“we laugh sometimes because the tunes（声调）arc really hard to learn.”said Dou.But she said that now she would watch Peking Opera on TV.　　“After all.I am no longer a layman.”she said.　　Since 2008.schools around the country have been teaching students Peking Opera.It’s part of a plan to introduce young people to the country’s artistic traditions.Clearly,Dou’s school has been taking the job seriously.　　Yang Ning,14,is Dou’s classmate.She has been studying Peking Opera since she was 8.She is a member of the school’s Peking Opera club.　　Yang said she had learned a lot from Peking Opera.　　“I learn a lot of history from the operas.” she said,“I’ve also found out about many ancient poems,since there are so many of them in the operas.”　　Yang doesn’t think everyone can learn to sing Peking Opera well,but she does say that it’s helpful for all people to learn about it.　　“The more you learn about it,the more you understand it.If people do study it,this old art form won’t disappear.It would be a great pity if it did!” she said.
