请顺便解析为什么要这么改的原因

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~~

what do you mean by saying that?
devoted to sth/doing sth

1.What do you mean by saying that?
2.,he has devoted his whole life on benefiting mankind.

1. 第一句话应该是没有问题的。如果必须要改的话，就要把 to say that改为by saying that。
2.首先是 devote ……to……致力于……，把……奉献给……，献身于……，
所以原句就要改为 he has devoted his whole life （to）benefiting mankind.
这其中的to是介词的哦，所以后面必须用动词...
