1. to take something for granted = to believe something to be the truth without questioning or testing it; to expect something to be available all the time; to fail to appreciate something (считать само собой разумеющимся; принимать как само собой разумеющееся)
We take it for granted that women can join the armed forces.
Until 9/11, I took it for granted that America was safe from such things as terrorist attacks. I no longer take that for granted.
2. to take sides = to choose one side of an argument (принимать чью-либо сторону в споре; стать на чью-либо сторону)
Have you ever taken sides in an argument before you’ve heard both of them?
I didn't want to take sides, but rather to spur a healthy debate.
3. to take its toll = to cause a lot of harm, especially in a gradual way (нанести тяжелый урон; плохо сказываться на чем-то)
Stress takes its toll on employee productivity.
Lack of sleep was beginning to take its toll on me.
