For them, going on holidays is educational. Consequently, this sort of travelers will move from place to place every few days. If

13、 they visit lots of places in a short span of time, there is no way that they can get a proper feeling of a place or fully appreciate the local food and wine.

17、kersD.Forget Your Work and Enjoy Yourselves2Because humans are at the top of the food chain, they are particularly vulnerable to the effects of nondegradable (不可能降解的)pollutants. This was clearly illustrated in the 1950s and 1960s when residents living near Minamata Bay, Japan, developed nervous diso

18、rders, shaking, and paralysis(瘫痪，麻痹) in a mysterious widespread. Over 400 people died before authorities discovered that a local industry had released mercury(水银，汞) into Minamata Bay. This highly toxic element stored up in the bodies of local fish and eventually in the bodies of people who consumed

19、the fish. 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 earth“s environment. They improve water and

20、 air quality, provide living places for plants and animals, and provide food and medicines. Any or all of these ecosystem functions may be impaired or destroyed by pollution.

Fortunately, this seldom happens. One reason

27、is that out at sea, waves moving in one direction almost always run into waves moving in a different direction. The two sets of waves tend to cancel each other out. Another reason is that water is shallower near the shore. As a wave gets closer to land, the shallow bottom helps reduce its strength.

28、But the power of waves striking the shore can still be very great. During a winter gale, waves sometimes strike the shore with the force of 6,000 pounds for each square foot. That means a wave, 25 feet high and 500 feet along its face, may strike the shore with a force of 75 million pounds. Yet the

29、waves, no matter how big or how violent, affect only the surface of the sea. During the most raging storms, the water a hundred fathoms (600 feet) beneath the surface is just as calm as on a day without a breath of wind.（分数：4.00）(1).According to the passage, destruction caused by high waves occurs _

32、high waves striking the shore is _.（分数：0.80）A.constantB.equalizedC.variableD.perpetual(5).From your reading of the passage, which of the following is tree?（分数：0.80）A.At a depth of 1,200 feet the effects of a violent surface storm are frightful.B.A submarine commander navigating his vessel at a depth

33、 of 700 feet will not be affected by a ranging surface storm.C.A typhoon 500 miles out at sea can stir up the ocean floor.D.If high waves can strike the shore with a horizontal force of 75 million pounds, the vertical force of such waves can have an even greater effect upon the ocean floor.3Dear, We
