Is Bich's son weren't sick, she wouldn't be worried
If you are not quiet, I will kill you
If Nga felt happy, she wouldn't eat sweets
Unless it rains tonight, Thanh still go to bed early
If Hien weren't hungry, she wouldn't walk quickly
If you don't hurry, I'll go alone
If Ngan weren't lonely, she wouldn't cry so much
Unless it is nice, we'll drink coffee
If My had much money, she could lend Nhan
If Jack were a fish, he could be a shark
