24、. More recently research has revealed that many chemical pollutants are harmful to the human beings. Pollution also has a dramatic effect on natural resources. Ecosystems such as forests, wetlands, and rivers perform many important services for the earths environment. They improve water and air qual

A carrier is flexible in a way that armies and air forces are not because it can influence events merely by being seen. The power of an aircraft carrie
40、r can act as a visible deterrent (威慑物 ) to enemy aggression. A carrier is also flexible because it operates on the ocean. Unlike a land air base, no other country has to be consulted about where a carrier can go and what it can be used for because most of the ocean is considered international water
41、and not part of any one country. This freedom allows carriers to move from one trouble spot to another quite easily.

44、ypes are currently in use or are being built. Of these, over half are in service in the U.S. Navy. A typical American nuclear powered aircraft carrier can cost well over $ 4 billion and take five years to build. 36 In the sentence “Aircraft Carders are a powerful and extremely flexible part of a nat

49、000 robots were operating in the industrialized world. Over 500,000 were used in Japan, about 120,000 in Western Europe, and about 60,000 in the United States.
