1 Should she feel tired, let us know  right away.

2  Should you be busy then, I'll take  care of that.

3 Were I you, I would  never talk to my parents like that.

4 Were we to have more money, we could buy this house.

5 Had he not cheated, she wouldn't have  broken up with him.

6 Had our daughter  been more hard-working, she could have gotten into that university.

7  Had our son not gone to bed late last night, he wouldn't be sleepy now.

8  Had the kids cleaned the house this morning, we wouldn't have to do  this now.

9  Were that guy friendlier, he could have made a lot of friends at the party last night.

10 Were I you, I would have taken the job.
