Passage Three Be careful of those who use the truth to deceive (欺骗). When someone tells you something that is true, but leaves out important information that should be included, he can create a false impression. For example, someone might say, 'I just won a hundred dollars on the lottery (抽彩给奖法). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!' This guy's a winner, right? Maybe, maybe not. We then discover that he bought two hundred tickets, and only one was a winner. He's really a big loser! He didn't say anything that was false, but he omitted important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just as dishonest. Dishonest politicians often use this method. Let's say that during Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of the politicians opposing her runs an ad saying, '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 claims, so they try to mislead you with the truth. An ad might claim, 'Nine out of ten doctors recommend Yucky Pills to cure nose pimples (丘疹).' It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company. This kind of deception happens too often. It's a sad fact of life. Lies are lies, and sometimes the truth can lie as well. What does the writer want to tell us with the example of the lottery winner?
