重点语法 一般现在时(常与频度副词never, seldom, sometimes, often,usually, always等连用)
重点详解
1 I always come to school by bus.
by+交通工具名称,表示使用某种交通方式,中间不加限定词,如果交通工具前有a, the, my 等限定词,就不能用by,而是用in或是on.
on the train=by train on his bike=by bike in my car=by car.
巧辩异同 on foot 与 walk on foot “走路”,是介词短语,位于句末。walk “走路”,是动词,
go to…on foot= walk to I often go to school on foot. =I often walk to school.
