Many people who saw the film = 名次 就像 =they
were afraid to swim in the sea = afraid
连句 用when
when they rememberd the scenes
用in which 是because 的意思 因为上面用了连词when,如果不想中断句子就同in which
也可以说 .the scenes,because they had eaten by the shark
因为是过去式,要表达saw the film发生第一,所以描述发生第二的事情 都用were或had + 过去分词.那样就注重表达第一个句子
简单例子
(people)were afraid to swim
复杂名次
(many people who saw the film) were afraid to swim
复杂名次+ 地点
many people who saw the film were afraid to swim(in the sea)
复杂名次+ 地点+ 解释(为什么会害怕游泳)
many people who saw the film were afraid to swim in the sea(when they rememberd the scenes)
复杂名次+ 地点+ (为什么会害怕游泳)+ 解释为什么想起情景就害怕?

因为有人被鲨鱼吃掉过
in which= because
