改错.1,what do you mean to say that?2,he has devoted his whole life benefiting mankind.
请顺便解析为什么要这么改的原因

1.
what do you mean by saying that?
翻译：你说这话什么意思啊?
这个是一个固定的句式,没有太多道理,记住就好了.
2.
he has devoted his whole life to benefiting mankind.
翻译：他将他的一生献给了造福人类.
这里考察devote oneself to doing 的用法,所以benefit要用现在分词形式benefiting,不能用benefited.
望采纳,谢谢~~
