Translation of "Insists" in Chinese

Mother insists that we should be home by seven in the evening.

母親一定要我們在晚上七時前回到家中。

The eyes themselves can become selective, ignoring part of what is there, and the brain sometimes insists on seeing things that don't exist at all.

视觉本身具有选择性，既有看不到实际存在一些东西的情况，也有大脑判断看到了实际完全不存在东西这样的情况。
