I helped him studying English last Sunday.
这句话的意思就是
上个星期天我帮助他学英语。首先要说的一点是帮助某人干某事，就是
help sb do something。或者是help sb to do something。也可以是help sb with sth。所以这里面的studying应该去掉里面的ing。变成study。又因为这是一个一般过去时的句子，所以一般疑问句是，
Did you help him study English last Sunday？你上星期天帮助他学英语了吗？
同义句就是
Did you help him with English
last Sunday？或者是
Did you help him to study
English last Sunday？
多数情况下用的同义句是第一个。
