同学你好~
Shops cater for the do-it-yourself craze not only by running special advisory services for novices, but by offering consumers bits and pieces which they can assemble at home. 同学说的是这句话吗

by表示“通过，借助”某种手段，商店不仅为初学者提供专门的咨询服务，而且为顾客准备了各种零件，商店是通过这些手段，来满足顾客的。
May I pay by cheque?
我能用支票付款吗？
I will contact you by letter.
我会给你写信联系的。

祝同学学习进步~
