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
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:
Ever looked at the etching of a Blu-ray disc? It's oddly beautiful, refracting light like a rainbow while also offering copious digital storage.
看過「藍光光碟」的蝕刻版畫嗎?那是一種古怪的美,把光折射得如彩虹一般,同時還能提供豐富的數據存儲。
Turns out that pattern isn't just beautiful in the light, it's also useful when it comes to the light. Because the particular structure of a typical Blu-ray disc happens to be one that boosts the light absorbing ability of photovoltaics. That's according to a study in the journal Nature Communications. [Alexander J. Smith, Repurposing Blu-ray movie discs as quasi-random nanoimprinting templates for photon management]
而那種美不僅是能夠使「光線」變美,對「光能」來說也非常有用。因為一個典型的藍光光碟的特殊結構恰巧能夠提高光對太陽光電的吸收能力。該研究結果出自《自然通訊》雜誌的一項研究。【亞歷山大‧J‧史密斯:重新利用藍光影視碟片,將其作為光子管理的「擬隨機」奈米模板】
The semi-random pattern of microscopic bumps and indents that store a movie on a Blu-ray disc also helps solar cells absorb light by spreading it around more widely within the cell—where a greater percentage of it is then available to generate a current.
這種能將電影存儲到藍光光碟上的微觀碰撞和縮進的半隨機模式,同時也能幫助太陽能電池通過在其內部更廣泛的擴散來吸收光線——從而增強電池本身能夠產生電流的百分比。
Researchers at Northwestern University made the discovery by transferring the pattern of the Jackie Chan movie Supercop to the top of a plastic solar cell. They found, to their surprise, that the Supercopped solar cell boosted performance by more than 20 percent.
美國西北大學的研究員們通過將成龍主演的電影《超級警察》的樣品,傳送到一塊塑料太陽能電池頂端,得出了此發現。他們驚奇地發現,這塊「超級」太陽能電池的發電力增強了20%。
Of course, Supercop is not a special movie, except maybe to hardcore Chan fans. Dramas, documentaries and even cartoons worked just as well. Which means all that Blu-ray disc-making prowess could get applied to a new purpose: clean power.
當然,除了對硬漢成龍的鐵桿粉絲們來講,《超級警察》本身並不是什麼特殊的電影。除電影外,電視劇、紀錄片及卡通動漫都有此效果。這就意味著所有藍光光碟產生的威力都能被應用到一個新使命中去:清潔能源。
