Jack ran to do a side turn, jumped up and grabbed the monkey rod, and pulled himself across rapidly alternating his hands.

杰克跑着做了一个侧手翻，跳起来抓住猴杆，双手交替着将自己迅速拉到对岸。

邦德推测，这种交替循环可能是海-水间循环变化的证据，因此也会影响地球的气候。

Also, skilled artisans did not work by the clock, at a steady pace, but rather in bursts of intense labor alternating with more leisurely time.
