參考答案:1.你星期天经常干什么？
What do you often do on Sundays？
“经常”应该用often，usually是通常，always是总是。而且，本句是一般现在时态，不应该用doing
2.她星期日经常去哪？
Where does she often go on Sundays？
3.谁在擦黑板？
Who is cleaning the blackboard now?
4.他星期天不帮妈妈，他常写作业。
He doesn't help his mother on Sundays.He often does his homework.
词组help sb. （to） do sth.帮助某人做某事
英语句子中一般都用句号除非前面是词组，如：At the weekend，he often… at the weekend 是词组，所以才用逗号。
