2023年職稱英語理工類A級閱讀理解試題答案

　　Invisibility Ring

　　When a person sees an object，his or her eye senses many different waves of visiblelight as they bounce off the object.The eye and brain then work together to organize thesesensations and reconstruct the objects original shape. So，to make an object invisible，scientists have to keep waves from bouncing off it.And they have to make sure the objectcasts no shadow.Otherwise，the absence of reflected light on one side would give the obiectaway.

　　The scientists new invisibility device is the size of a drink coaster and shaped like aring.The ring is made of a special material with unusual ability.When microwaves strike thering，very few bounce off it.Instead，they pass through the ring，which bends the waves allthe way around until they reach the opposite side.The waves then return to their originalpaths.

　　When the researchers put a small cdpper loop inside the ring，it，too，is nearly invisible. However，the cloaking device and anything inside it do cast a pale shadow.And the deviceworks only for microwaves，not for visible light or any kind of electromagnetic radiation.So，Harry Potters invisibility cloak doesnt have any real competition yet.

　　invisibilityn.看不見，無形 spectrumn.光譜

　　microwaven.微波 ultraviolet ray 紫外線5ri:kEn5strQktp

　　radiantadj.輻射的 wavelengthn.波長

　　練習(xí)：

　　A　can now make an invisible cloak of the same kind as he uses.

　　C　try to invent a device Similar in idea to the invisible cloak he uses.

　　2、What is true of microwaves?

　　B　Their wavelengths are longer than those of visible light.

　　D　They are visible to the human eye.

　　A　It is made of a special material with unusual ability.

　　C　Microwaves pass through it when they strike it.

　　4、What does the word coaster mean in the passage?

　　B　A vessel engaged in coastal trade.

　　D　A resident of a coastal area.

　　A　scientists have not found out how his cloak works.

　　C　the cloaking device works only for microwaves.

　　參考答案：

　　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(jù)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。

　　4、A　第四段第一句告訴我們，科學(xué)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(mào)易的船;C：過山車，摩天輪;D：海岸地區(qū)居民。
