The tea gardens in Sri Lanka are actually large estates(种植园). The best tea usually comes from plants grown on high grounds, the cool hilltops with rows and rows of tea plants. The plants are about one metre apart. The plant is often pruned so that it remains only 60 to 90 centimetres high. Pruning is important because it encourages the growth of tender hoots, or young leaves. It is from these shoots that the best in got.

Practically all the tea pickers are women. The estates like to employ women pickers because they are more careful. Their thin fingers can easily remove the twin leaves and new shoots from the plant, which are the parts used for processing(加工)tea. The pickers carry large baskets into which they throw their pickings. A skilled worker can harvest between 9 to 14 kilogrammes of tea leaves a day. Usually new shoots can be picked from the plants about every ten or fifteen days.

Processing tea shoots into the familiar dry tea leaves requires great care and skill. There are various methods of processing depending on the type of tea required. For black tea, the young green leaves are first spread out on shelves to dry. This process removes much of its water and the leaves become soft. After this, the leaves are passed through heavy rollers. This operation will press the leaves for juices which give the tea both its colour and taste. Then the leaves are spread out on floors and left to ferment(发酵)under wet conditions. Fermentation develops the rich taste of black tea. The fermented leaves are then dried with a hot­air blower until they become rolled­up black leaves. The final step is to sort and grade them before the black tea is ready for sale to countries all over the world.

The idea of light pollution has developed with the increase of lights in cities. In many areas, this light makes it difficult or impossible to observe stars and planets in the night sky.

There are a number of reasons why light pollution is important. One has become clear at the Mount Wilson Observatory near Los Angeles, California. Today, light from Los Angeles makes the night sky above Mount Wilson very bright. It is no longer an important reasearch center because of light pollution.

Light pollution threatens to reduce the scientific value of research telescoples in other important observatories. They include Lick Observatory near San Jose, California and Yerkes Observatory near Chicago, Illionis.

Light pollution is the result of wasted energy. Bright light that shines into the sky is not being used to provide light where it is needed on Earth. Poorly designed lighting causes a great deal of light pollution. Lights that are brighter than necessary also cause light pollution.

Most people in America are surprised to find out that they are able to see our own galaxy(星系),the Milky Way, with their own eyes. But about three­fourths of Americans cannot see the Miky Way because of man­made light.

Objects in the night sky are resources that provide everyone with wonder. But light pollution threatens to prevent those wonderful sights from being seen.

A.in cities                               B.in the country

C.in wild areas                           D.in developing countries

A.children          B.grown­ups         C.students          D.observatories
