新素材 科普知识 People have been facing the problem of finding clean energy for a long time. More than a hundred years ago, people started placing turbines(涡轮机) in rivers. The moving water turned the turbines and produced power. More recently, companies have begun using the power of the wind to provide electrical(电的) energy. Both of them avoid the use of fossil fuels and help build a cleaner environment.
In the past few years, however, another energy can be chosen on the coasts of the United States. People there now want to use the power of the rise and fall of ocean water each day. Like wind power, tidal power provides a very clean energy.
Wind comes and goes and there is no way to control it. Tidal power is predictable(可预测的) and it happens every day. People know exactly when the tide will come in and go out.
In some ways, tidal turbines are very similar to those used to make electricity from wind. For example, both types of turbines must have a very heavy foundation(地基). Wind turbines need them because they are very tall and might fall over in high winds. Tidal turbines need them because they are placed in narrow openings on the ocean floor. In these places, the force of the moving water is very strong.
In other ways, the two types of turbines are quite different. The blades(桨叶) of a tidal turbine must be much stronger than those of a wind turbine. A company called Verdant Energy built some model turbines for its project in New York City's East River. When they put the turbines into the river, the blades broke off at once. The company had to design new, stronger blades before the project could continue.

【分析】
做这类英语阅读理解题，需先通读原文把握主旨，再针对各小题问题回原文定位相关内容，逐一对比选项排除错误答案，选出正确选项。具体到各题：34题需定位潮汐能的描述，对比选项；35题需分析给定句子的逻辑，匹配对应段落；36题需梳理文章结构，判断组织方式；37题需提炼文章核心内容，确定最佳标题。
【解析】
34题：根据原文第五段“The blades of a tidal turbine must be much stronger than those of a wind turbine.”可知，潮汐涡轮机的桨叶需要更坚固，对应选项D。A选项原文未提及潮汐能生产成本低；B选项原文提到潮汐能用于美国海岸，并非任何地方；C选项错误，潮汐能需要涡轮机，故排除A、B、C，选D。
35题：给定句子“However, it does have one big advantage over wind power.”表转折，强调潮汐能比风能的优势。原文第三段先讲风能的不足（风能不稳定），接着讲潮汐能可预测的优势，逻辑衔接紧密，因此该句适合放在第三段开头，选B。
36题：文章先介绍风能，再引出潮汐能，对比两者的特点、涡轮机的异同，核心是描述风能和潮汐能两种清洁能源，对应选项C。A选项文章并非按时间顺序；B选项未涉及问题与建议；D选项重点不是化石燃料的使用，故排除A、B、D，选C。
37题：文章围绕潮汐能展开，对比风能，突出潮汐能的优势，核心是探讨潮汐能是否是比风能更好的选择，对应选项D。A选项未体现潮汐能；B选项偏离重点；C选项仅涉及涡轮机，未突出潮汐能，故排除A、B、C，选D。
