As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.
　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

Stepping into a pool of water is common enough, but who could ever imagine stepping into a pool of fish? In February of 1974, Bill Tapp, an Australian farmer, saw a rain of fish that covered his farm. How surprised he must have been when he heard many fish hitting against his roof!

　　 What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a combination of wind and storm.

　　When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners, collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before dropping them on fields, houses, and astonished people.

　　Although they seem unusual, fish-falls occur quite frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as common as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.

Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.

　 In the early years, these schools were much alike(*similar).Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated(*毕业),most of them became ministers or teachers.

　In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard’s law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history.

　As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.
