can you pl rewrite the following sentence 1.the glass broke because you were careless if you _________________________________

That sentence will never make good sense if you keep this word order. Having two adverbial clauses at the end of the sentence is very awkward.

Move the "if" clause to the beginning of the sentence, and try it from there.

If ... , the glass broke because you were careless.

thank you writeacher how could the same sentence be converted into conditional clauses if you__________________________________

Here's one possibility:

If you ran through the gift shop, then the glass broke because you were careless.

I'm still not happy with that sentence, but it's better than putting both adverbial clauses together.

thank you but take a look at my version 1. if you were not careless the glass would not break 2. if you had been careful the glass would not have broken will they beaccepted

Yes, both of those are fine -- be sure to put capitals, commas, and periods in all the right places!!

If you were to rewrite the sentence "The glass broke because you were careless," you could say:

The glass broke due to your lack of caution or negligence.
