What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by deflected (反射) light. We see color because most of the things reflect 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 (吸引) and turned into (变成) heat (热能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.
1.When something reflects light, we can _____.
A. see its color B. see its heat C. not see its color D. see nothing
2.Something looks white because it reflects _____.
A. some light B. no light C. all light D. most light
3.the dark-colored clothes are warm because ____ is taken in.
A. more light B. less light C. more color D. less color

The world itself is becoming much smaller by using modern traffic and modern communication means(交流方式). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must try to control the growth of population at the same time.

Tony Buzan’s grades were going down at university. Disappointed with his low marks, he went to the library to find a book on how to use his brain. He was directed to the medical section. Confused, he said to the librarian, “I don’t want to take my brain out, I just want to learn how to use it.” Her reply was simple: “There’s no book on that.”
“I thought to myself,” says Buzan, “if I buy a little radio, I get an instruction manual (说明书). If I buy a microwave, I get an instruction manual. But for the most important machine in the world, no instruction manual?”
Fifty years later, Buzan has become the world’s leading speaker on the brain and learning. In the late 1960s, he invented the mind map, a visual representation of thought processes.
This kind of thinking has become a popular tool for planning, organizing, problem solving, and communicating across the world. He has since authored and co-authored over 100 books that have appeared in more than 30 languages.
“I think in most cases, people use less than 1 percent of their brains,” he says.
But how do you expand this 1 percent? How do you become the best student you can be?
According to Buzan, the answer is simple. You take a section of whatever it is that you are trying to learn, he says, and you read it for its essence (精髓、要素). Then you make a mind map of all the important details. For a truly effective mind map, you start with a colored image in the center of your page. Draw the first image that comes to mind on the topic you are mind mapping. Branch off from your central image and create one of your main ideas. From your main branches draw some sub-branches and from those sub-branches you can draw even more branches. He emphasizes that you should use plenty of images and colors as these help with memory recall and encourage creativity.
By using this visual format (形式), according to Buzan, your mind will begin to make associations that will help you remember more information for longer periods of time.
Buzan believes that traditional note-taking methods, such as lists and summaries, do not stimulate the brain’s recall capacity or ability in the same way. Because of this, students will often find themselves locked away in their rooms for hours, trying hard to memorize separate details. Buzan believes that for a more effective and lasting way of studying, you must first understand how your brain works.
“Everyone is born smart,” he says. “You just have to learn how to learn.”
