Example sentences in SuperMemo

I usually read the example sentences I added to the answer when I run SuperMemo but I don't know if its necessary to do it every day. I am talking about example sentences that I read before. If I have never read the example sentence obviously I am going to read it.

You should add example sentences of a word in your question field and its definitions in the answer field. The definitions are there for your understanding of the word. In the case of example sentences, your full focus should be on reading them and understanding them and grading yourself according to your understanding. One more caveat: you do not have to memorize and re-read definitions in your answer field. If you don't mind, can you provide us a mini/short sampleof your learning items?
