What is colour? Why do some of the things around us look red, some green, others blue?
Colours are really made by reflected (反射) light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.
Some of the light is reflected and some is taken in (吸收) and turned into heat. The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured clothes are warmer in the sun than light-coloured clothes.
1.When something reflects light, we can _______ .
A. see its colour B. see its heat
C. not see its colour D. see nothing
2.The dark-coloured clothes are warm because _________ is taken in.
A. more light B. less light
C. more colour D. less colour
3.In summer ________ make people feel cool.
A. dark-coloured clothes B. red-coloured clothes
C. green-coloured clothes D. light-coloured clothes

What can you do on the Internet? Many of us like to read the news, buy things and play games. Some students now have a new use for the Internet – helping them with their homework.
Tina, 14, from Shenzhen, Guangdong, often searches online for the answers to her math problems. She said sometimes she and even her parents don’t know the answers to the problems, so she has to turn to the Internet.
“I can see how other people work out these problems and learn from them,” Tina said. “It’s easy and saves time.”
But not all the students welcome this. Leo, 15, from Hangzhou, Zhejiang, thinks it may make students stop thinking.
“We should think over the problems first. Simply copying the answers won’t improve our abilities. ” he said.
In the eyes of Wang Zhaoming, a Shanghai teacher, the success of all this is down to the students. If they use the Internet properly (适当地), it could be a good tool for study, Wang said.
“Students should first think about the problems by themselves. As for the online answers, they should choose the best among different ones. The most important thing is to know the logic (逻辑) behind the answers,” he said. “Don’t be shy to ask teachers and classmates the next day if you don’t understand the answer.”
