2道英语题 请大家帮帮忙

It is generally considered unwise to give a child(）he or she wants.

()has helped to save the drowning girl is worth praising

都是名词性从句

Answer 1

It is generally considered unwise to give a child what he or she wants.大家普遍认为孩子要什么就给什么是不明智的
句子结构：
It is+adj.结构，it指代后面的“give a child what he or she wants.
”，意思是“...是不明智的”
give sb. sth.，what即为sth.而此处的sth.既是what he or she wants，意为“给某人想要的某物”。
who has helped to save the drowning girl is worth praising.
那个搭救落水女孩儿的人值得赞扬
句子结构：
“who has helped to save the drowning girl”为who引导的主语从句
be worth + doing是固定用法
