问题补充：

He goes to school early on workdays Saturday and Sunday.

A. except

B. besides

C. and

D. beside

答案：

(答案→)A. except

B. besides

C. and

D. beside

解析：句意：除了星期六和星期日在上学的日子他很早就去学校。And和；beside在……旁；except除了；besides除了。besides:(prep.)除……之外 它这个除是包含的 .except:(prep.)除了……之外

后面的范围比主语的范围小,除去的和非除去的是同类事物，用except,不包括所引事物。常与no, none, nothing等否定词或all, everyone, everything等连用，但不可用于句首。所以选A。
