Be aware of those who use the truth to deceive. 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. 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, or maybe not. We then discover that he bought two hundred tickets, and only one was 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.
Untrustworthy candidates in political campaigns often use this tactic. 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 her opponents runs an advertisement, 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 advertisement might boast, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples(粉刺).” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.
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.
【小题1】Which statement is true according to the article?

Of all the things that have effects on your future, I believe that personal growth is the greatest. Many people talk about sales growth, profit growth, and possession growth, but none of these will happen without personal growth. In fact I’d like to have you memorize a most important sentence. It is “The key to your future is you yourself.”
There are many things that will help you better your future. If you belong to a strong, dynamic（充满活力的）and progressive company, that will help. Good training will help. Strong leadership will help. If the neighbors stay civil（文明的）, that will help. If your relatives don’t trouble you, that will help…All these things will help. We can go on and on with the list; but remember, the things that I’ve covered above just play minor（次要的）roles in helping you reach a good future. The major cause doesn’t lie outside. It lies inside.
Strangely enough, when two different men work in the same company, the first person may earn $1,000 a month, while the second may earn $10,000 a month. What causes the difference when they have the same job, use the same tools, and get the same training?
The cause of the difference lies in believing, in trying, in accepting failures, in thinking, in a smile at people around, and in the ways of dealing with problems. All of these can be major causes of your good future. You can see all these come from inside. In fact, the real difference is you yourself. You are the key to your future. Teens are the most wonderful and important period in life. If you want a great future, begin to improve yourself from now on!
