[单选题]CHonesty comes in many forms. First there’s self-honesty. Is what people see the real article or do you appear through smoke and mirrors? I find that if I try to be something I’m not , I feel unsure of myself and take out a part from my PBA(personal bank account ).I love how singer Judy Garland put it, “Always be a first-class version(版本) of yourself , instead of a second-class version of somebody else .”

A. Then there’s honesty in our actions. Are you honest at school, with your parents , and with your boss ? If you’ve ever been dishonest, I think we all have, try being honest, and notice how whole it makes you feel. Remember, you can’t do wrong and feel right. This story by Jeff is a good example of that:
B. In my second year of study, there were three kids in my math class who didn’t do well. I was really good at it. I would charge them three dollars for each test that I helped them pass. I’d write on a little piece of paper all the right answers, and hand them off.
C. At first I felt like I was making money, kind of a nice job. I wasn’t thinking about how it could hurt all of us. After a while I realized I shouldn’t do that anymore, because I wasn’t really helping them. They weren’t learning anything, and it would only get harder down the road. Cheating certainly wasn’t helping me.
D. It takes courage to be honest when people all around you are getting away with cheating on tests, lying to their parents, and stealing at work. But , remember , every act of honesty is a deposit（储蓄）into your PBA and will build strength .
E. 49. The underlined part “appear through smoke and mirrors” in the first paragraph means “ ” .
F. to be honest
G. to be unreal
H. to become clear
I. to come from an imagined world
