今天下午你不用自行车时我可以用一下吗？

Could I use your bike this afternoon when you don't use it?

骑自行车是个好方法，不用花一分钱就能让孩子们走出家门，呼吸新鲜空气。

Bicycling was a great way to get the kids out of the house and into the fresh air without spending any money.

很快你就会清楚地看到，不用汽车而是仅仅步行或骑自行车，对你自己和环境都有好处。

In stating the obvious, by leaving the car behind and simply walking or riding a bike you are doing both yourself and the environment good.
