（T="True," F = False)
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.

【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。

阅读下面的材料，判断下列句子是否符合短文内容。符合的写T，不符合的写F。
（T = True, F = False）

     We can see some overhead bridges(天桥) in Yueyang city. There is one near the No.1 People's
Hospital. Another is in front of the Bus Station. As we all know, it is not safe to cross a busy road.
These bridges can help people cross the roads safely. Overhead bridges have the same use as street
crossings.
     Many people think it great trouble to go through overhead bridges. The old and the young think it's
difficult for them to climb up and down the steps of the overhead bridges. But why does the government
build so many overhead bridges? That's because old people and young children walk slowly. And when
they cross a busy road using a street crossing, the traffic will be held up or maybe stopped, or even a
traffic accident may happen. With the help of the overhead bridges, people and the traffic can move at
the same time.
    A lot of money has been spent building these overhead bridges. People, old or young should always
use them. This can help stop traffic accidents from happening.

(     )1. There is only one overhead bridge in Yueyang city.
(     )2. It is dangerous for people to cross a busy road.
(     )3. All the people like using overhead bridges instead of street crossings.
(     )4. Overhead bridges help people and the traffic move at the same time.
(     )5. An overhead bridge can help stop a traffic accident from happening.

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.
