阅读下列材料：     

材料一：我国具有陆地生态系统的各种类型，包括森林、灌丛、草原和稀树草原、草甸、荒漠、高山冻原等。由于不同的气候、土壤等条件，又进一步分为各种亚类型约600种。如我国的森林有针叶林、阔叶林和针阔混交林；草甸有典型草甸、盐生草甸、沼泽化草甸和高寒草甸等。除此以外，我国海洋和淡水生态系统类型也很齐全。     

材料二：水稻丛矮病是一种危害水稻生长发育的病毒性疾病，很难防治。后来科学家们发现了一个野生水稻种群，这个种群对草丛矮缩病具有较强的抗性，从而为培育抗草丛矮缩病的水稻新品种找到了必要的基因。     

材料三：位于我国大别山的某县，曾经是森林茂密、鸟兽繁多、气候宜人的地方，后来，人们在山坡上毁林开荒，改种农作物，破坏了当地的生活环境，使得林中的鸟类和哺乳类动物大量减少。鸟类减少，各种农林害虫失去了天敌的控制，就大量繁殖起来，给农作物和树木造成了严重的危害。

请分析回答：

（1）材料一说明了：____       。

（2）材料二说明了：____       。

（3）材料三说明了：每种生物都生活在一定的  ____中，并且与其他的生物相联系。生物圈中生物的数量减少或灭绝，必然会影响它所在的  ____，当后者发生剧烈变化时，会加速生物灭绝和栖息地的丧失，因此，保护生物多样性的最有效的措施是____        。

In June of 1973, nine whales beached on the Florida coast. Beaching means swimming out of the ocean onto the beach, and usually dying there. No one knows why they do it, but a number of whales beach themselves every year. Some people think beaching is an accident.
Perhaps the whales get confused. Scientists who studied the beaching of three dozen whales in Australia think the whales may have been confused by loud noises, Whales can tell where they are by sounds. They send out sounds and listen as they travel past or bounce off objects. Two days before these thirty-six whales beached, loud guns had been fired for two hours. The loud sounds may have confused the whales. Their confusion might have caused them to wander into low water.
Whatever the reason whales beach, it is a sad event. People try to save them, but very few beached whales live. One whale that was rescued from beaching in Florida lived for forty-five days. That is the longest a beached whale has ever survived. And it lived that long only because it got attention from doctors.
All over the world, scientists rush to whale beachings as soon as they hear about them. They hope to learn why whales beach, and how to save them.

Whale beachings are sad events because ______.

A．people know the whales are going to die

B．the whales have to be carted away and buried

C．the whales cannot be used as food

D．no one can use the beach on those days
