I know the young man in green jacket ____brother is my good friend.

Do you know why different animals or pests have their special colours? Colours in them seem to be mainly used to protect themselves.

Some birds like eating locusts（蝗虫）, but birds cannot easily catch them. Why? It is because locusts change their colurs with the changes of the colours of crops .When crops are green, locusts look green .But as the harvest time comes, locusts change into the same brown colour as crops have .Some other pests whose colours are different from plants are easily found and eaten by others .So they have to hide themselves for lives and appear only at night.

If you study the animals’ life, you’ll find the main use of colours is to protect themselves .Bears, lions and other animals move quietly through forests .They cannot be easily seen by hunters because their colours are much like the trees.

Colours are useful not only on the land , but also in the sea .A kind of fish in the sea can give out a kind of black liquid（液体）when the fish face danger. The liquid spreads over quickly, so they cannot be found by their enemies and can quickly swim away. That is why they can live safely though they are not strong at all.

Bai Yansong, a famous TV host, expressed his support for students wearing green scarves (绿领巾) at a primary school in Xi’an. He wore a green tie on a TV program on October 19, 2011. “I just want the students to know that I’m also wearing green. And we are all great people and are as good as those wearing red scarves.”
The First Experimental Primary School in Xi’an made children with poor schoolwork and behavior wear green scarves. Parents whose children wore green scarves were angry. “The children still need their self-esteem (自尊心) even though they are very young, and they know the green scarf means something is not quite right,” said one mother. Now, the school has stopped the practice.
Educational expert Li Zhenxi said that primary and junior high school students have strong self-esteem. They are eager to be respected and understood. Punishment will hurt them. “It’s better to encourage them rather than separating some ‘bad’ students,” he said.
A survey made by the Ministry of Education (教育部) shows that 75 percent of students feel nervous and scared when the teacher is about to announce their grades. Some schools have done better in protecting students’ privacy and encouraging them. In American schools, teachers post test results on the wall. Instead of using student names, they use secret numbers. This way, students know their secret numbers and can check their own grades only. Some teachers might call the students up to the desk and tell them their scores one at a time.
But test scores are not the only measures of a student’s ability. Everyone has his own strengths and everyone can make great progress by working hard.
