23、 doing sth.意为“阻止做某事”。3Abe appointed as.被任命为。4C因houses与burn是被动关系，故排除B、D两项。burn.to death烧死；burn to the ground全部焚毁。5B分析句子结构可知此处应用非谓语动词作状语。I与experience之间是主动关系，且非谓语动词所表示的动作发生在句子谓语动作之前，故用现在分词的完成式。6Dbe about to do.when.刚要突然/这时；第二个空考查“as.as.”结构，中间用形容词或副词的原级。7Cadj./adv.enoughto do意为“足够做”。8Amake ones way to/towards向走去。.1.B从第二段的“Animals often seem to know in advance that an earthquake is coming”一句看出动物能够预测地震。2D从最后一段的最后三句可以看出一些动物能够预测地震是因为它们能够发现“tiny changes in air pressure，gravity，or the magnetism (磁力) of Earth”，因此选D项。3C从第三段的美洲狮和最后一段看出只是一些动物能够在地震前出现奇怪行为，但是，并没有确切地发现所有的动物怎样知道什么时候发生地震。4C作者的目的是在呈现一种新的发现。
