Answer 1

答案：C;B;A;B;D;C;C;D;B;A;B;A;C;C;B;C;A;D;D;A
解析：

1．C　　依常识判断，从第一句中live on volcanoes可确定。 　　2．B　　选项A与C易于否定。选项B与D均有可能，通读全文后再确定B。 　　3．A　　bottoms of the ocean是海洋底部。 　　4．B　　略。 　　5．D　　then意为“后来”。 　　6．C　　由于是“洋底的情况”，当然选below the water's surface，即“水面以下。 　　7．C　　push its way out from意为“从……冲出来”。 　　8．D　　hot center of the earth，因地球中心为炽热岩浆。 　　9．B　　had forced its way through…指火山从地壳穿过（喷出）不是毫无阻拦地，而是冲破地壳的挤压，所以用forced。 　　10．A　　同第11小题。 　　11．B　　这两小题指熔化的岩浆遇冷的海水而冷却变硬凝固。 　　12．A　　指随着熔岩不断涌出，一层层冷却后的岩浆堆积于洋底。 　　13．C　　选项C与D貌相似，high enough是正确表达。 　　14．C　　略。 　　15．B　　was born即“产生了”或“生成了”。 　　16．C　　broke down短语有“粉碎，分化”等含义。 　　17．A　　…carried by…，过去分词短语做后置宾语。 　　18．D　　become green with plants指由绿色植物覆盖，是自然状态，而garden和yard是人为的产物，在此不妥。 　　19．D　　从下文中active一词来判断，可以否定A与B项。从前一句“经过数千年”的论述来判断，是still。 　　20．A　　略。
