People usually talk about two groups of colours: warm（温暖） colours and cool colours. Scientists think that there are also two groups of people: some people like warm colours and other people like cool colours. The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active(活跃的). The cool colours are green, blue and purple. These colours unlike warm colours, are relaxing. Where there are cool colours, people are usually quiet.

Warm colours make people happy and hungry, scientists think that a warm colour such as red or orange, is a good colour for a living room or a restaurant.

Cool colours make people calm. For example，school walls are always painted green because green makes students feel calm. It is also good for the students’ eyes.

However, almost everyone agrees that warm colours remind (使想起) people of warm days and cool colours remind them of cool days. Because in the north (北方) the sun is low during winter, the sunlight are quite blue. Because the sun is higher during summer, the hot summer sunlight are yellow.

1.__________is warm color.

A. Green　　 B. Blue　　 C. Red　　 D. Purple

2.Cool colours make people feel______.

A. calm　　 B. happy　　 C. active　　 D. hungry

3.Which is the best title?

C. Warm colours　　 D. Cool colours

They run, jump, play with their children and catch small animals for food. But now they have to stay in cages or small rooms in the zoo. They do not have to find food by themselves. Because the zoo keepers（饲养员）feed them. They just eat, walk and sleep every day. Their life in the zoo is quite different from that in the forest because they are not free.
