He is eighty years old and fit as a fiddle. 他八十岁了，身体硬朗得很。

Fit是"身体好"的意思,fiddle是"小提琴"。 要是一个人说他fit as a fiddle,那就好比是一把琴的弦和音调都调得很好。请听下面这位年轻人谈谈他是怎样保持健康的:

I think my health is important, so I don't smoke or drink. I eat lots of vegetables and fruit, and I do exercises three times a week. These things help to keep me fit as a fiddle. 因为我的健康是很重要的。所以,我不抽烟,也不喝酒。我吃好多蔬菜和水果。我每个星期锻炼三次。这些都使我能保持身体健康。

美国人现在的寿命也越来越长。下面就是一个人在说他的祖父:

My grandfather looks as if he's sixty but he's really eighty years old and fit as a fiddle: he still has his own teeth, doesn't need glasses, and walks four miles every day. 我的祖父看起来像一个六十多岁的人。可是实际上,他已经八十岁了。而且他还非常健康:他不用装假牙,看东西也不用眼镜,每天还走四英里路。

身体很好的八十岁老人在美国不能说是罕见的事。但是,牙齿没有坏,看书不用戴眼镜,这实在令人感到惊奇。老人为了保持身体健康每天散步,做运动也并不稀罕。可是,四英里并不是很短的行程。想必这位老人肯定有他特殊的养身之道。
