在拼命修改方程式之余，爱因斯坦还抽时间与他的竞争对手希尔伯特一起参与跳一种难看的西班牙舞蹈--方丹戈双人舞。

四级词汇讲解:
本句的主干是Einstein took time off。句中的to engage in an awkward fandango是不定式短语，作目的状语，其中，take time off是“抽出一部分时间”的意思;take time off from doing sth.是“从做某事中抽出时间”的意思。如:

The teacher encourages us to take time off from studying hard to exercise ourselves.老师鼓励我们在努力学习之余抽时间锻炼身体。

engage in sth.是“参加某事或忙于做某事”的意思。如:
I have no time to engage in such a boring activity.我无暇参加这样无聊的活动。

awkward的意思是“尴尬的;难看的”。如:
Her words put me in a very awkward position.她的话使我陷入极其尴尬的境地。
