word="C">C</span>文章的第一段告诉我们，科学家还没有发明哈里波特使用的那种隐身衣，所以不能选 <span word="A">A</span>;该段还告诉我们，科学家已制造了，一种装置，这种装置能使自身或置于其中的物体不被微波发现，所以<span word="C">C</span>是正确选择，也就是说，科学家发明的隐形装置和哈里波特的隐身衣仅仅在概念上相同，这同时说明<span word="B">B</span>和<span word="D">D</span>是错误的选择。 3.<span word="B">B</span>第四段第三句说，当微波到达装置表面时，<span word="very">very</span> <span word="few">few</span> <span word="bounce">bounce</span> <span word="off">off</span>。<span word="very">very</span> <span word="few">few</span>是几乎没有的意思，所以选择<span word="B">B</span>。其他选择所述内容都可以很容易在该段中找到。 5.<span word="CA">CA</span>句在短文中没有提到;按文章的内容<span word="B">B</span>不是正确的说法;文章最后一段说，<span word="And">And</span> <span word="thedevice">thedevice</span> <span word="works">works</span> <span word="only">only</span> <span word="for">for</span> <span word="microwaves">microwaves</span>，<span word="not">not</span> <span word="forvisible">forvisible</span> <span word="light">light</span>，所以<span word="C">C</span>是正确选择 </p>
