答案與題解:
1.C文章的第一段告訴我們,科學家還沒有發明哈里。波特使用的那種隱身衣,所以不能選 A;該段還告訴我們,科學家已制造了,一種裝置,這種裝置能使自身或置于其中的物體不被微波發現,所以C是正確選擇,也就是說,科學家發明的隱形裝置和哈里波特的隱身衣僅僅在概念上相同,這同時說明B和D是錯誤的選擇。
2.B第三段最后一句中告訴我們,A是錯誤選擇,B是正確選擇。該段第三句說,微波與可見光一樣都是一種輻射能,所以C的說法是錯誤的,不能選擇;根據該段第一句:with wavesof light that the human eye can see和第三句:Like visible light,可以得知D是錯誤的說法,也不能選擇。
3.B第四段第三句說,當微波到達裝置表面時,very few bounce off.very few是幾乎沒有的意思,所以選擇B.其他選擇所述內容都可以很容易在該段中找到。
4.A第四段第一句告訴我們,科學家的這個隱形裝置和一個杯墊差不多大小,所以A是正確選擇。coaster是一個多義詞,其他幾個選擇是該詞的其他意思,B:從事沿海貿易的船;C:過山車,摩天輪;D:海岸地區居民。
5.CA句在短文中沒有提到;按文章的內容B不是正確的說法;文章最后一段說,And thedevice works only for microwaves,not forvisible light,所以C是正確選擇。
