Language points
The answer to our question about watching television were also interesting.
对我们提出的有关看电视的问题的回答也颇有意思。
1）此句中的基本意思是The answer were also interesting, 主语the answers 为复数，故使用were。
2）请注意本句中answer和question两个名词后的介词搭配。表示“......”的答案时，answer后要用介词to，这是一种固定的搭配。又如：
There's no easy answer to this problem.
这个问题没有简单的答案。
Her answer to your question is big “NO”!
她对你所提出问题的答案回答就是一个大大的“不”字！
Language points
So start exercising before it's too late!
所以要赶快锻炼起来，不要等到来不及了！
it's too late的字面意思是“为时太晚；来不及了”，是英语中的一个常用表达。例如：
Now you know you're wrong, but it's too late.
此处it's too late与before共同组成从句，表示“不要等到为时已晚；
不要等到来不及的时候；趁着还来得及”。这也是一种常见的用法，例如：
You should work harder before it's too late to catch up.
你应当更加努力，别等到为时过晚而赶不上了。（你现在用功还赶得上。）
