上学坐汽车用英语可以说作 "take the bus to school" 或 "commute to school by bus."

这个表达方式来源于英语中常用的 "take + transportation" 结构表示坐某种交通工具,例如:

I take the train to work every day. (我每天坐火车去上班。)
She takes the subway to her classes. (她坐地铁去上课。)

另外,"commute" 是一个常用的动词,指的是通勤,例如:

He commutes by car from the suburbs to the city every day. (他每天开车从郊区通勤到城市。)
I used to commute to work by bike, but now I take the bus. (我以前骑自行车通勤上班,但现在我坐公交车。)

下面是几个例句:

I take the bus to school every day. (我每天坐公交车上学。)
She commutes to school by bus. (她坐公交车上学。)
We have to leave early to catch the bus to school. (我们得早起赶公交车去上学。)
