问题描述：
my sister often go to school_______是by a bike还是on the bike
答
BY BIKE
ON FOOT
答
My sister often goes to school by bike.
答
by bike 固定搭配
答
on the bike是正确的。
或者是by bike，不加a。
by a bike 是不对的。
答
on the bike 对.
用by时注意：by后面直接加交通工具.而on / in 等要先加修饰词,再加交通工具.
如 by bike = on a/the bike by car = in a/the car
没有by a bike这种写法
