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：
Robots have evolved in leaps and bounds in recent years, but they still cannot safely leap or bound. They have to move carefully. If a robot were to fall from an elevated surface, for the most part it would crash down like a bag of rocks. Not ideal if that robot is on a rescue mission.
近幾年機器人經歷了跨越式發展，但它們仍不能安全地進行跳躍活動。而且，它們不得不很小心地走動。如果機器人從一個較高的地方跌落，多數情況下它會像一袋石頭一樣朝下猛撞。若恰好這個機器人在執行救援任務，那結果會很不理想。

So a team of Georgia Tech researchers wants to produce robots that are more agile, by making them literally cat-like. Specifically, the plan is to create a robot that can emulate a cat's uncanny ability to calculate the best landing angle, adjust its body midflight and land on its feet.
喬治亞理工學院的一組科研人員希望能生產出一種更靈活的機器人，或者說把它們設計得像貓一樣。具體說來，該計畫是想設計出這樣一個機器人：它能仿真貓所具備的估計最佳著陸角度、在跳躍中調整身體、並用腳著陸的「神秘能力」。

So far the research team has been able to build a robot capable of computing landing angles during test falls. They hope to eventually give the robots joints that can twist or flip their bodies to stick the landing, regardless of the angle.
目前，該小組已成功造出一個在跳躍測試中，能計算著陸角度的機器人。科研人員希望最終給予機器人能使它們軀體彎曲、翻轉的關節，讓它們可以穩穩著陸，而且不必理會角度問題。

To do that, they'll need better motors and servos. The ones available today are not fast enough to sufficiently adjust a robot's body in real time.
為實現這一願望，他們需要更好的馬達和伺服系統。如今現有的馬達和伺服系統還不夠快，不能及時的充分調整機器人的身體。

Baby steps. David Belle didn't develop the cityscape acrobatic activity known as Parkour overnight. And the typical house cat has had tens of thousands of years to perfect the soft landing.

還只是起步階段。大衛‧貝爾也並非在一夜間搞出名為「跑酷」的都市雜技活動。而典型的家貓則有幾千年的時間來完善軟著陸。
