保险带

Unfortunately belts are worn only by a small percentage of drivers and passengers.

不幸是,只有数量很少驾驶员和旅客保。

One study showed that forty percent of those killed in auto accidents could have been saved if they had been wearing seat belts.

"一项研究表明,车祸中失去性命人中百分之四他们上保话本来是可以得救。"

According to one study, belts are worn only by about fifteen percent of drivers and passengers in cities, and only nine percent in small towns.

根据一项研究,在城市里只有百分之五驾驶员和乘客保,在小城镇,只有百分之九。
