来帮个忙
After finish his homework he went on --------a letter to his parents.
A,write B writing Cwrote D to write

B

B gong on doing sth

选B,go on doing sth,继续做某事

After finish his homework he went on ---D-----a letter to his parents.
A,write B writing Cwrote D to write
go on to do sth 继续做另一件事 这个另一件事 和之前的事情是不同的
写完作业后,他继续写信给他的父母
写作业 和写信 是不同
因此用D
希望能够帮到楼主

B
这里考查的是go on 词组的固定搭配用法~
go on +doing
所以选B
