And environment differs in different parts of the world. Ecology is the science of how living creatures and plants exist together and depend on each other on the local environment. Where an environment is undisturbed, the ecology of an area is in balance. But if a creature dies out or an alien(相异的) species is introduced, then the ecology of this area will be upset. Man is a part of the environment and has done more to upset the ecology during his short span on earth than any other living creature. He has poisoned the atmosphere and polluted both land and water. He has wasted the earth’s natural resources with no thought for the future. He has killed a lot of precious animals for his delicacies (精美的食品)on the table and for his elegant overcoats. Since man has done so much damage, it is up to man to try to put matters right. And the sooner he does something about it, the better. 1)【R1】______ is everything that surrounds us. 2)【R2】______ is the science of how living creatures and plants exist together. 3) The ecology of an area is【R3】______ , where an environment is undisturbed. 4) Man is【R4】______ of the environment. 5) Man has poisoned the atmosphere and【R5】______ both land and water.Environment is everything that surrounds us: plants, animals, buildings, country, air, water—in fact everything that can affect us in any way.

Stock markets in Paris, London, Tokyo, Shanghai and New York are among the largest and most well-known. The stock market, also called stock exchange, is a place where people can buy or sell shares of a factory or a company. And each share means certain ownership of a factory or a company. Different people go to stock markets. Some are rich, who want to get more money than they have. Others are not rich, who buy stocks and try to become rich. Still others buy stocks as part of their plan to save money. Of course, investing money in the stock market is not the safest way to make money. No one can tell exactly whether the shares will be doing well. The factory or the company may do badly. Then the stocks will go down, and investors will lose money. The stock may go up or down for a number of untold reasons. Everyone wants the stock to go up, but sometimes even if a factory or company does a good job, the stock may still go down. No wonder going to the stock market is often compared to gambling. All are anxious to make money by "gambling" in the stock market. Factories and companies that need money are pleased that so many people are willing to "gamble".Environment is everything that surrounds us: plants, animals, buildings, country, air, water—in fact everything that can affect us in any way.
