问题 The invisibility cloak can make something invisible by wrapping ______.
There is always a "shadow" behind the uncloaked object because ______.
选项
答案the object causes an interruption in the electromagnetic waves/the object interrupts the electromagnetic waves
解析 由题干中的shadow定位到文章第3段首句An uncloaked object would cause an interruption in the waves，creating a "shadow" behind the object．文中的现在分词结构creating a "shadow" behind the object作状语，表示结果，由此可知前面叙述的是产生“影子”的原因，因此应围绕此分词结构前面的内容回答。
