【解析】本文是一篇记叙文，讲述了海豚的作用，它不仅代表平安，还可以保护水手免于遭到鲨鱼的攻击。
（1）考查冠词。luck“运气、好运”，是不可数名词，因此不能使用不定冠词。故将a删掉。
（2）考查分词。see sb./sth. doing, “看见某人某物正在做某事”，故将swum改为swimming。
（3）考查时态。，主语Their presence是单数形式，结合后半句的谓语动词will，可知该句整体时态为一般现在时。故将meant改为means。
（4）考查名词的数。information“信息”，是不可数名词，故将informations改为information。
（5）考查定语从句。which suffer shipwreck from sharks是一个限制性定语从句，修饰先行词 sailors，指的是人，故将which改为who或that。
（6）考查固定句型。it is no wonder that …固定句式，“不足为奇”故将there改为it。
（7）考查动词。known是一个表示短暂性动作的动词，long表示较长时间，因此应该使用表示延续性动作的动词，故添加been。
（8）考查代词。此空应使用与主语相对应的代词，故将its改为their。
（9）考查分词。副词修饰动词，故将exact改为exactly。
（10）考查名词。approaching为形容词，后面应该接名词，故将dangerous改为danger。
