．Which is the best title for the passage?

　　B. How Solar Energy Could Reshape the West

　　C. How the Effects of Power Plants Can Be Reduced

　　D. How the Problems of the Highways Have Been Settled

　　答案：B。主旨大意题。文章借助于铁路和公路对美国的影响，要说明的是太阳能这种新的电力系统对美国西部地区会有什么的影响。阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项。For thousands of years, mankind has produced plants and animals to create more desired and useful plants and animals. For example, modern com has been produced to such a large size that it is no longer able to reproduce without man’s assistance. Modern dairy cows produce too much milk and if they are not often emptied of milk, they could leak, burst, become infected, and possibly die. Besides, most dogs raised by people can not survive in the wild even with special training.

　　Since natural evolution is extremely slow and mankind’s selective production programs only take a few generations to produce a completely new species, natural evolution has already taken a back seat to mankind’s production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths (猛犸象) probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i»t cause most of the destruction during man’s rule of the world.
