The two largest islands of the British Isles are Great Britain and Ireland. England, Wales and Scotland together form Great Britain. Scotland, lying in the northern part of Great Britain and bordering(接壤)England on the south, is half the size of England and Wales, having an area of about 76 000 square kilometers. Most of Northern Scotland is mountainous area known as the Scottish Highlands. In the center of Scotland there are the Central Low-lands, and the south is waving, hilly area known as the Southern Uplands which rise to 800m. There are many rivers in Great Britain, but they are not very long. The rivers which run to the east are longer than the ones which run to the west.

In Scotland the main rainy winds come from the Atlantic Ocean. The west part is wet with an average(平均) rainfall of up to 200cm while the east is dry with about 75cm. The winters are cold with an average January temperature of 4℃. The summers are cold and warm but rarely hot.

Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in a million.

People have made a census (普查) to colors of mor e than four thousand kinds of flowers and discovered that only eight of them are black.

As we know, sunlight is formed by seven different colored lights.The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals, are easy to be harmed by light temperature.

Black flowers can take in all the light waves which cause the flowers to dry up in the high temperature. So black flowers can rarely survive sunlight. But red flowers, yellow flowers and orange flowers can protect themselves from sunlight by reflecting the red light, yellow light and orange light, each of which has a large quantity of heat.
