I'll help the children learn French -------.

我个人觉得选择myself,意思是说,我会亲自帮助孩子们学习法语。既然放最后面,应该是状语,状语的话应该是说主语要做什么。相当by myself(只是相当于, by myself与myself有本质区别的,在于by myself即说明我亲自来,不用谁帮我；而myself,有尝试的意味,下同)。 例子:http://www。flickr。com/photos/28153783@N08/4946263409/中的那句"if harold won't do this for me, then I'll just do it myself。"还有相信你也听说过DIY这个词,意思是do it yourself。这里的代词yourself也是做状语成分,相当于by yourself,即自己来做(亲历亲为) 。
