Our father was a struggling , but I always knew he was . He never criticized us, but used to bring out our best. He’d say, “If you pour water on flowers, they flourish.

When he realized I had made up my mind, he said, “Richard, when I was 23, my dad me to go into law. And I’ve regretted it. I wanted to be a biologist, I didn’t pursue my . You know what you want. Go fulfill it.”As turned out, my little publication went on to become Student, a national for young people in the U.K. My wife and I have two children, and I’d like to think we are bringing them up in the same way Dad me.1.A. biologistB. managerC. lawyerD. gardener2.A. strictB. honestC. specialD. learned3.A. praiseB. courageC. powerD. warmth4.A. thinkB. imagineC. rememberD. guess5.A. unnecessaryB. unkindC. unimportantD. unusual6.A.
