Inside the shelter, he latched the door, and looked around to see that his family was squared away. Now it began. The waiting.

see在這句中是檢查的意思，譯文是檢查查詢他的家人是不是就位。如何有個選擇性是不是的意思。是譯文錯了嗎？

to see that從句在此是looked around的目的狀語，因此see的語義不可能是“看到”。此處的to see that=to see to it that, 意為“核實...、”確認“。英文解釋為：
tomakesurethat someonedoessomething or that somethinghappens

譯文應為：在防空洞里，他插上門閂，環顧四周以便確認他的家人已經就位。然后他們就開始等待。
