我认为，这是一个省略句。如果你能提供上下文更好。(There were )almost as many boys reported dieting as girls and many of the children surveyed said they were already dissatisfied with their body shape. boys有两个后置定语，一个是reported ，另一个是 dieting as girls。这里有个点特别容易搞混。as many boys ...as girls 和 dieting as girls 只出现了一个as girls，它起两个作用，一个是呼应前面的as many，也同时作现在分词dieting的方式状语。 翻译：据报道，像女孩那样在节食的男孩数量几乎有在节食的女孩那样多并且据调查（surveyed)许多孩子对他们的身材已经感到不满了。
