解析
【分析】
首先通读全文,明确文章围绕海洋探索的主题,结合每个空的语境、语法规则及固定搭配逐一分析:15空需填冠词修饰可数名词单数journey;16空对应one of结构,需用名词复数;17空结合or not确定宾语从句引导词;18空表目的用不定式;19空考查spend的固定搭配;20空是固定短语instead of;21空由than确定比较级;22空修饰动词用副词;23空作宾语用代词宾格;24空考查被动语态。
【解析】
15. 考查冠词。journey为可数名词单数,此处表泛指“一段旅程”,故填a。
16. 考查名词复数。“one of + 形容词最高级 + 可数名词复数”为固定结构,表“……之一”,achieve的名词形式为achievement,复数为achievements,故填achievements。
17. 考查宾语从句引导词。根据句中or not可知,此处用whether引导宾语从句,表“是否”,故填whether。
18. 考查非谓语动词。此处表目的,需用不定式作目的状语,故填To find。
19. 考查固定搭配。spend time (in) doing sth. 是固定搭配,意为“花费时间做某事”,故填diving。
20. 考查固定搭配。instead of是固定短语,意为“代替,而不是”,故填of。
21. 考查形容词比较级。由句中than可知,此处需用bad的比较级worse,故填worse。
22. 考查副词。此处修饰动词survive,需用success的副词形式successfully,故填successfully。
23. 考查代词。此处作动词made的宾语,需用we的宾格形式us,故填us。
24. 考查被动语态。wonders与unlock之间为被动关系,情态动词can后接动词原形,故填be unlocked。
【答案】
15.a 16.achievements 17.whether 18.To find 19.diving 20.of 21.worse 22.successfully 23.us 24.be unlocked
【知识点】
冠词;名词复数;非谓语动词
