 洪欣老師推薦：托福聽力最好的課外教材：60-Second Science
 康康精選托福會考的主題，堅持每天精聽一定會進步的哦!!

 建議方法：
1. 先聽兩三遍 (不看文稿)
2. 再一句一句聽寫 (每句都要聽寫數遍，直到寫出85%以上的字)
3. 最後check文稿，看哪聽不出來，單字沒背過，還是發音不熟。
4. 堅持天天聽，就能每天進步哦。

 只有音檔怎夠，聽不懂地方，不用怕，康康幫你準備好中英文稿了：

 中英文稿：
There's a scene in Bladerunner, Ridley Scott's sci-fi classic, when Harrison Ford's character, Deckard, is about to interview Rachael, played by Sean Young, to test whether she's a real human—or a replicant. ["It's too bright in here."] On cue, the floor-to-ceiling windows dim, shading the room from the golden sunlight outside.
在雷利•史考特的科幻作品中的《銀翼殺手》有這樣一個場景，當哈里森福特扮演的角色迪卡德在將要和肖恩•楊扮演的雷琪兒會面時，測試了一下她是否是一個真實的人類——而非一個複製品。就在這時候，落地窗逐漸變暗，遮蔽了從外面照射出的金黃色的陽光下的整間屋子。

It was a beautiful Hollywood effect when the movie came out in 1982. And now it may not be that far from reality. Because researchers at Harvard recently designed a material that, with a shot of electricity, can transform a glass window from transparent to opaque in less than a second.
這部電影在1982上映時，給好萊塢增添了美好印象。而現在，這種場景也變的不是那麼虛幻了。因為哈佛大學的研究人員們已經研究出一中帶電的材料，這種材料能將玻璃窗在一秒鐘以內從透明狀態轉變為模糊的狀態。

The team built the window by sandwiching glass between two sheets of a transparent, balloon-like rubber material, laced with silver nanowires. As is, the material is clear. But apply voltage, and the nanowires are attracted to each other ever so slightly across the glass—which deforms those rubbery sheets just enough to scatter light, causing the glass to cloud up. They describe the device in the journal Optics Letters.
該研究小組構建的玻璃窗是三明治樣的兩層透明的氣球樣的橡膠材料，交織著銀質的納米細絲。像這樣的材料，就是透明狀態。但是，施加電壓後，這些納米絲會在 玻璃層之間稍稍靠近彼此——這種變形剛好使得橡膠層把投射進的光線散射掉，從而轉變透明的玻璃為模糊狀態。他們對該設備的描述已經發表在《光學通訊》雜誌 上。

Study author Samuel Shian, a materials scientist, says this smart glass is cheaper than others, and uses minimal power—much less, for example, than something like a curling iron. And, since it's flexible and foldable, he says it could even be used for things like camouflage uniforms, to switch, for example, from green and brown to white and gray. "This would be very useful when the background landscape suddenly changes, such as during early snowfall."
該研究的作者Samuel Shian，是一位材料學家，他表示，這種智慧玻璃比其它複合材質的造價低，而且耗能小——比如，比一個電捲髮器的耗能還少。而且，因為它的狀態可以靈活 變化以及可折疊，他表示，這種材料可用于製作向是迷彩軍服之類的特殊物品，可以轉換不同狀態，比如說，從綠色和棕色變為，白色和灰色。這樣的話當背景突然 發生變化，比如說在降雪早期，就十分有用了。

Bladerunner was set in Los Angeles in 2019. Meaning Shian and others still have about three years to turn one bit of science fiction into science fact.
當時，銀翼殺手的場景設置是在2019年的洛杉磯。也就是說，Shian和其它同行們，還將有3年的時間把這種科幻小說中出現過的設想轉變為真實的科學實踐。
