您好，空格填介词（to）。

must see to something = 确保 …… 能被完成

As a school bus driver, he must see to it that every child on the bus arrives at school safely every morning.

Answer 2

be see to it that 一定要注意

构
(2)句子结构为 see to it (形式宾语)+ that 真正宾语从句

(3) see to 意思‘照料;处理;照看;注意’特别备注: see to 后面不能直接接宾语从句,需要在宾语从句前加上一个“形式主语 it 其结构为 see to it + that 从句。
