How it works

After seeing the cake photo, they could not resist the urge to buy it—and ended up buying it.

The two forms in the diagram mean the same thing: you cannot resist doing something.

To form it, remove ない and add ずにはいられない. The special form of する is せず.

Here, you act because you cannot hold back your own feelings, rather than because someone ordered you to.

The example does not mean “not checking.” Hearing that an offer is for a limited time makes the speaker unable to resist checking it out.

The speaker could not keep from going to see it. So in the past-tense example, they actually did go.
