What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by reflected(反射) light. We can see colors 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 light is reflected. But the other light is taken in and turns into heat. The darker the color is, the less light is reflected, and the more light is taken in. For this reason, dark-colored clothes are warmer in the sun than light-colored clothes.
小题1:Colors are made by reflected light
小题2: Something looks white because it reflects all kinds of light.
小题3:In the dark we can’t see anything because all the things don’t reflect any light
小题4: When the other light is taken in, it will be reflected in the end.
小题5:In the sun, the warmest clothes must be light-colored.
答案
小题1:T
小题1:T
小题1:T
小题1:F
小题1:F
解析
小题1:根据第一段第二行可知,颜色是由反射光产生的。故本句正确,涂T。
小题1:根据第一段的第五行可知,全部反射掉,就显示为白色。故本句正确,涂T。
小题1:根据第二段的第二行The darker the color is, the less light is reflected可知,在夜里,物体不反射光。故本句正确,涂T。
小题1:根据第二段第一行is taken in and turns into heat可知,光被吸收后转化为了热量。故本题错误,涂F。
小题1:根据第二段最后一句dark-colored clothes are warmer in the sun可知,颜色越深越吸光,本题错误,涂F。

Operation Smile was started by a doctor and his wife. In 1982, together with some volunteers, they went to Philippines to help children who had holes in their lips or inside their mouths. It was very difficult for them to eat and drink. These volunteers worked very hard. But they worried that they could not carry on with the work because they were short of money. Then they decided to start a charity so that they could help these needy children. They called it Operation Smile.
Operation Smile works in more than twenty developing countries and has cured over 10,000 children who have problems with their mouths. Operation Smile has won many prizes for its work and in 1999 they even started a special event called“The World Journey of Hope”. 5,000 children in 18 countries are cured during the event.
On the other hand, Operation Smile trains local doctors and nurses in developing countries so that they can continue to help children when Operation Smile has left. As to the children with much more serious problems, they will send them to America for further treatment.
So show your kindness and generosity to the needy children now. You can send your donation to Operation Smile at local banks. Many thanks from the children who can smile now will come to you.
