With alarming regularity,we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people,nature,and the environment.
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals,beaches,and land spoiled by the oil.Unfortunately,when many of these chemicals are used,,more damage is caused to the environment,especially to lives in the sea.
Of all of today’s environmental disasters ,an oil spill may actually be one of the least serious.Although oil is poisonous,it is a natual material.In the end,it breaks down naturally.There are,of course,long-term effects,but it is usually more serious in the short term.
Nature by itself woks better than chemical materials,but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean,If you go there today,you will find it hard to see any sign that it ever happened.
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental
damage.Interestingly the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run I
We shoule be thinking more about reducing our dependency on oil,Governments should be encouraging research into new technologies,such as cars run by solar power(太阳能),electricity,
hydrogen,and so on.Much of this research has ,in the past been held back by the oil,gas,and coal.
If the world’s millions of cars were 10% more efficient(高效的)—and the industry could easily produce cars at least twice as efficient?we would need many fewer tankers crossing the oceans each year.If this happened,the risks of oil spills would be reduced,and the air we breathe would be cleaner and fresher ,too.

Yet some people wonder if the revolution in travel has gone too far. A price has been paid, they say, for the conquest (征服) of time and distance. Travel_is_something_to_be_
enjoyed,_not_endured(忍受). The boat offers leisure and time enough to appreciate the everchanging sights and sounds of a journey. A journey by train also has a special charm about it. Lakes and forests and wild, open plains sweeping past your carriage window create a grand view in which time and distance mean nothing. On board a plane, however, there is just the blank blue of the sky filling the narrow windows of the airplane. The soft lighting, inflight films and gentle music make up the only world you know, and the hours progress slowly.How does the writer support the underlined statement in Paragraph 2?
| A.By giving instructions. |
| B.By analyzing cause and effect. |
| C.By following the order of time. |
| D.By giving examples. |
