本题考查澳大利亚重要的交通工具。

Among workers and students 18 years and older, three out of four drive privately owned vehicles. Four out of five report that they never use public transportation, mainly because of lack of service or scheduling inconveniences. One in eight Australians regularly uses public trains and buses, notably in the larger cities, and one in 20 walks or cycles. About 8% do not travel on a daily basis.

约有四分之三的工人或满十八周岁的学生拥有自己的私家车。约有五分之四的人们几乎不使用公共交通工具，主要是因为服务匮乏，而且有时很不方便。在一些大城市中，约有八分之一的人们会经常乘坐公共交通工具，包括火车与公共汽车；仅有二十分之一的人们步行或者骑自行车出行。另外还有百分之八的人不是每天都出行的。故选C。
