问题
The invisibility cloak can make something invisible by wrapping ______. [br] What does David R. Smith want to convey when he says "...except when they’re magic" in the last paragraph?
选项
答案
It seems impossible to build a cloak people wish to have.
解析
由题干定位到文章末段。Indeed,it may be impossible to build a cloak that can block all the colors found in the visible spectrum..通览全段可知,作者通过引用David R. Smith博士的话来说明此段首句的内容,就目前的技术而言,制造一件人们理想中的隐形斗篷似乎不太可能,因此可以围绕此句回答。
