三语法核心总结

it 作形式主语

it comes as a surprise to learn that …

have sth. done

have had special cages made（请人做笼子）

be frightened out of one's wits

吓得惊慌失措

as a result

结果（承接原因）

have sth. done 结构：have + 宾语 + 过去分词，表示「请（让）别人做某事」或「遭遇某事」。本课 they have had special cages made 是「他们请人做了特别的笼子」，made 与 cages 之间是被动关系。同类还有 have my hair cut、have the house painted。
it comes as a surprise to learn that …：句中的 it 是形式主语，真正的主语是 to learn that giant fish are terrifying the divers …。这一句型表示「得知……令人吃惊」，come as a surprise 是固定搭配。
fish and chips 作主语用单数：fish and chips 被视为「一道菜」，是一个整体，所以谓语用单数 has。同类还有 bread and butter、a knife and fork 等。
