1.) System requires a good DC convert in order to provide a higher voltage which is used to drive the system core. 2.) System requires a good DC convert in order to provide a higher voltage used to drive the system core. 3.) System requires a good DC convert in order to provide a higher voltage to drive the system core. 4.) System requires a good DC convert in order to provide a higher voltage for driving the system core. 以上四句是否文意及文法都沒有錯誤呢? 我想知道這幾句的差別 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 129.217.129.131
