本题为根据汉语提示完成句子的词汇题,解题思路是:先明确括号内的汉语释义,再结合句子中的语法线索(如冠词、情态动词等)确定单词的正确形式。具体步骤:1. 第1题前有不定冠词an,需填元音音素开头的名词,对应“序言、介绍”的单词;2. 第2题前有a,填单数名词,对应“视频”的单词;3. 第3题直接对应“海啸”的名词;4. 第4题情态动词may后接动词原形,对应“导致”的单词;5. 第5题对应“预警”的名词,结合语境填写。
【解析】
1. 句意:这个页面为灾难博物馆提供了介绍。an后接元音音素开头的名词,“介绍”对应introduction,故填introduction;
2. 句意:我们看了一个关于自然灾害安全的视频。a后接单数可数名词,“视频”对应video,故填video;
3. 句意:当海啸预警来临时,海边的人应该跑到高地。“海啸”对应名词tsunami,故填tsunami;
