一个简单的英语问题!
Of course, New York is the ideal place for such an interesting study, because there is no shortage of tall buildings. There are plenty of high-rise windowsills to fall from! 当然,纽约是进行这种有趣的试验的一个理想的地方,因为那里根本不缺乏高楼大厦,有的是高层的窗槛从上往下坠落.
这里的from不太懂
There are plenty of high-rise windowsills to fall from! 有的是高层的窗槛从大楼坠落。 不是要这样翻译吗？？？
啊到底怎么翻译啊！！！
