Beware of those who use the truth to cheat. When someone tells you something that is  36   , but leaves out important information that should be     37  , he can create a false impression.
For example, someone might say, “I just    38    a hundred dollars on the lottery. It was great. I took that dollar ticket back to the store and     39   it for one hundred dollars!”
This guy’s a winner,    40  ? Maybe, maybe not. We then discover that he bought two hundred     41    , and only one was a winner. He’s really a big     42   !
He didn’t say anything that was    43   , but he deliberately left out some important  44  . That’s called a half-truth. Half-truths are not technically     45  , but they are just as not   46    .
Untrustworthy candidates in     47    campaigns often use this strategy. Let’s say that during Governor Smith’s last term, her state lost one million jobs and   48   three million jobs. Then she    49    another term. One of her opponents runs an advertisement   50  , “During Governor Smith’s term, the state lost one million jobs!” That’s true.    51   , an honest statement would have been, “During Governor Smith’s term, the state had a net gain of   52   million jobs.”
Advertisers will sometimes use half-truths. It’s    53   the law to make false claims so they try to mislead you with the    54   . An advertisement might boast (吹嘘), “Nine out of ten doctors recommend Yucky Pills to cure nose pimples.” It     55   to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.
This kind of cheat happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

C．interesting
