当一个人说two wheels are better than four的时候他的意思就是骑自行车比开汽车好。
- If you want to get healthy, get out of your car and onto your bike; two wheels are better than four!
- The traffic is really bad in the city so two wheels are definitely better than four.
值得注意的是，所谓two-for-one就是汉语里的买一送一，买一个送一个。
- I hope you like eating cabbage; I got them on a two-for-one offer at the supermarket, so we've got lots to eat.
