這篇很有意思哦!! 小夥伴們趕緊來聽。
今日主題：To Walk, You Have to Fall in Step
走路需要步調一致

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：
How many times has this happened to you? You start to fall, but then catch yourself and continue on your way. Well, new research shows that falling and catching yourself actually happens every time we take a step. And that we precisely place our feet as we walk to avoid taking a tumble during this ambulatory balancing act. The study is in the journal Biology Letters. [Yang Wang and Manoj Srinivasan: Stepping in the direction of the fall: the next foot placement can be predicted from current upper body state in steady-state walking]
這種情況發生過多少次？要摔倒的時候，一個踉蹌又接住自己，然後繼續走路。新的研究發現每次我們走路的時候，這種要摔倒，又接住自己的事總會發生。在走路 保持平衡過程中，我們儘量避免摔跤。這項研究發佈在生物學雜誌上。[楊王和里尼瓦桑：摔倒的傾向：下一步的腳步動態能夠從當前穩健的走路中，上半身的狀態 預測到。]

When humans walk, we put one foot in front of the other. But the way each foot lands can vary from step to step. This variation in foot placement can appear pretty random. But researchers decided to take a closer look.
人們走路時候，一隻腳在前，一隻腳在後交叉進行，但是每隻腳落地的方式都不相同。這種腳位的變化相當隨意。但是研究者決定近距離的觀看一下。

They fitted 10 volunteers with motion caption markers and then watched as the subjects walked on a treadmill. The investigators discovered that that they could predict exactly where each foot would fall based on the movement of the person's pelvis during the previous step. The body falls forward and sideways as we walk…and the feet come down in a way that restores our balance.
他們給了10個志願者安裝了動作捕捉系統，然後觀察他們在走步機上走路。調查者發現他們能夠根據一個人的先前步伐中骨盆的運動，精確地預測每一步的落地點。我們走路時身體向前傾……腳步前後交叉運動保持我們的平衡。

The findings could be useful for developing ways to help people with movement disorders regain their stability. The info could also make walking robots more surefooted. So they don't, ya know, fall down on the job.
這一發現對探索幫助運動有障礙的人重新找回平衡很有用。這個消息同樣使得走路機器人更平穩。所以，你知道，他們在此項研究的工作做的不夠好。
