Em cảm ơn chị ạ

Were I in your place, I would make a trip to England
Had he not wasted too much time, he wouldn't have failed in his examination last year
Had the car we saw yesterday been larger, we would have bought it
Were I you, I would save some of your lottery winning
Had I taken the English course you offered, I would have made much progress
Were my grandmother five years younger, she would play games with us
Had you not been so busy lately, I would have shown you how to play bowling
Look at those red curtains. Were those curtains blue, your room would look better
Had we chosen to live in a town instead of a city in 2010, we would not have had that many health problems
Were I thinner, I would look more attractive
