The trees have been on the earth for millions of years. 小题1: Disease(疾病) is destroying trees. For example, in the 1970s, many trees in Europe were killed by disease.
小题2: This new danger attacks all the forests and woods of Europe from northern Sweden to southern Italy. First the branches turn yellow and brown. Then the trees’ leaves fall. The roots and the trunk shrink(萎缩). Finally the trees die. In the Black Forest in southern Germany, 75％of the trees have been destroyed or killed．
小题3: Nobody knows exactly, but it is probably air pollution or acid rain(酸雨). Factories, power stations and cars give off tons of smoke with acid into the air. Sunlight turns these into something harmful which fall with rain or snow onto the trees.
What can be done about acid rain? 小题4:
Acid rain doesn’t always fall on the countries which produce the pollution. The wind carries it from one country to another. Badly, the governments don’ t want to spend money on it if it won’ t harm the trees in their own countries.
小题5: The rainforests of Asia and South America are being cut down for firewood and building materials. Something must be done. If the trees die, we will, too.

Since the earliest times, trees have always been very useful and important to man who made use of
them in many ways. Even today trees continue to serve man in many ways. Trees provide man with
fruits and building materials in the form of wood. Without trees it would be impossible to build houses,
boats and even bridges. Furniture such as tables, chairs and beds is made of wood.
In the tropics (热带地区) where it is very hot all through the year, trees protect man from the terrible
heat. They are also useful.in preventing good and rich top soil from being washed away during heavy
rains which are so common in the tropics. If there were no trees or vegetation (植被) of some kinds to
hold back the soil with their roots, heavy rains would wash away the rich surface soil that is so important
and necessary to agriculture. The result is that the land becomes a desert.
There are so many desert areas in the world. A long time ago these desert areas must have been very
rich fertile (肥沃的) areas, but since our ancestors (祖先) in the distant past had no enough knowledge
about science of nature, they cut down all the trees in the areas where they lived and never planted new
ones. By and by, the rich surface soil was blown away and washed away by strong wind and heavy rain.
In the end the land was turned into useless deserts where nothing could grow.
