黑色花为什么很少见

我们生活在姹紫嫣红，色彩缤纷的花的世界里，但是我们看到的黑色花却很少．植物学家对四千多种花的颜色进行了统计，发现只有8种黑色花，而且还不是纯正的黑色，只是偏紫色而已．

为什么会出现这种现象呢？原来花的颜色与太阳光及花瓣反射、吸收光有关．太阳光是由七种色光（红、橙、黄、绿、蓝、靛、紫）组成．光的颜色不同，其热效应不同．有色不透明物体反射与它颜色相同的光，吸收与它颜色不相同的光，黑色物体吸收各种颜色的光．花瓣比较柔嫩，为了生存，避免受高温伤害，它们吸收热效应较弱的光，而反射热效应较强的光．这就是我们看到红、橙、黄色花多，而蓝、紫色花较少的缘故．若吸收七种色光，受高温伤害就更大，花也更难生存，所以黑色花很少．

请回答下列问题：

（1）红花反射什么颜色的光，吸收什么颜色的光．

（2）材料中提到“光颜色不同，热效应不同”，请你比较红色光与蓝色光的热效应强弱．

     Northern Europeans spend a lot of time in their cold and cloudy winters planning their summer holidays.

They are proud of their healthy color when they return home after the holiday. But they also know that a

certain amount of sunshine is good for their bodies and general health.

     In ancient Greece people knew about the curing powers of the sun, but this knowledge was lost. At the

end of the nineteenth century a Danish doctor, Niels Finsen, began to study the effect of sunlight on certain

diseases, especially diseases of the skin. He was interested not only in natural sunlight but also in man-made

produced rays. Sunlight began to play a more important part in curing sick people.

     A Swiss doctor, Auguste Rollier, made full use of the sun in his hospital at Leysin. Leysin is a small village

high up in the Alps. The position is important, the rays of the sun with the greatest healing power are the

infra-red (红外线的) and ultraviolet (紫外线的) rays; but ultra-violet rays are too easily lost in fog and the

polluted air near industrial towns. Dr. Rollier found that sunlight, fresh air and good food cure a great many

diseases. He was particularly successful in curing certain forms of tuberculosis(结核病) with his"sun-cure".

     There were a large number of children in Dr. Rollier's hospital. He decided to start a school where sick

children could be cured and at the same time continue to learn. It was not long before his school was full.

     In winter, wearing only shorts, socks and boots, the children put on their skis after breakfast and left the

hospital. They carried small desks and chairs as well as their school books. Their teacher led them over the

snow until they reached a slope (斜坡)which faced the sun and was free from cold winds. There they set out

their desks and chairs, and school began.

     Although they wore hardly any clothes, Rollier's pupils were very seldom cold. That was because their

bodies were full of energy which they got from the sun. But the doctor knew that sunshine can also be

dangerous. If, for example, tuberculosis is attacking the lungs, unwise sunbathing may do great harm.

     Today there is not just one school in the sun. There are several in Switzerland, and since Switzerland is

not the only country which has the right conditions, there are similar schools in other places.

1. According to the passage, when did people began to realize sunlight played a more important part in

    the treatment of disease?

A. From ancient times.

B. At the end of the nineteenth century.

C. Not until this century.

2. Why are a Danish doctor and a Swiss doctor mentioned in the second and third paragraphs? 

A. Because they both made use of sunlight to treat illness.

B. Because they were the first people who used sunlight for treatment.

C. Because they were both famous European doctors.

D. Because they used sunlight in very different ways.

3. Dr Rollier set up a "sun-cure" school probably for the reason that _____.

A. most children could stay in his hospital

B. children could study while being treated

C. the school was expected to be full of pupils

D. the school was high up in the mountains

4. What can be inferred from the last paragraph of the passage?

A. "Sun-cure" schools are becoming popular everywhere.
