I am struggling to come up with sentences to write about in order to practice a grammar concepts, where can i find any sources for this?

Sorry if this is a silly question, usually after finishing up a lesson, i take a notebook and try to write as many sentences i can using the concepts i just learnt. But i cant come up with more than 5 sentences usually without being repeating the same idea. Where can i find any simple English sentences i can translate to in order to practice?
