What on earth does happiness mean? I can’t give you its exact definition, but I’m sure if you love and help         , you’ll get it.
I’ll never forget an old lady. She lives in     small house alone. It is said that her husband and her son    （die）in a road accident years ago. Her life is bitter, but she often helps others     a smile. Whenever it snows, she is always the first to clean the paths. She looks after several children living nearby. I am one of them. I often remember the stories she told us and her kind smile. Perhaps she is unlucky, but I think she is a happy person. Her life is full of   （laugh）and love.
But I’m sad to see some people getting their happiness in bad ways. They talk   （noisy）in cinemas and meeting rooms; they destroy trees to enjoy themselves and they laugh at others’ shortcomings. Perhaps they feel happy at that time,    they will never get true happiness because they    （lose）their personality already.
Now I know what happiness is.    means kindness, love and unselfishness. Above all, I have come to understand that   （bring）happiness to others is getting ourselves happiness.
