give up trying

She had finally given up trying to talk to him.

In fact, he had just about given up trying to understand his wife at all.

He gave up trying to find words for his feeling.

After a while, perhaps the Earth people will give up trying.

We will not give up trying to be the best in the world.

In the end, some people gave up trying to help.

So I just gave up trying to remember her right name.

She gave up trying to force the state after a while.

Finally she gave up trying to think of what to do.

In fact, by that point I had given up trying.
