When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture．For example, someone might say, “I just won a hundred dollars on the lottery(彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”This guy is a winner, right? Maybe, maybe not. We then discover that he bought $ 200 worth of tickets, and only one was a winner. He’s really a big loser!He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half truths are not technically lies, but they are just as dishonest.Some officers often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she tries another term. One of the persons who don’t support her says, “During Governor Smith’s term, the state lost one million jobs!” That’s true. However, an honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.’’Advertisers will sometimes use half—truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache. ”It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.This kind of thing happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.1.We may infer that the author believes people should ________.A. buy lottery tickets if possibleB. make use of half—truthsC. be careful about what they are toldD. not trust the Yucky Company2.How many examples does the writer give to show how the truth is used to deceive?A.
