     Have you ever heard the old saying, "Never judge a book by its cover."? This is a good rule to

follow when trying to judge the intelligence of others. Some people have minds that shine only in

certain situations. A young man with an unusual gift in writing may find himself speechless before a

pretty girl when he speaks. He may not be able to find the right words. But don't make the mistake

of thinking him stupid. With a pen and paper, he can express himself better than anybody else.

    Other people may fool you into overestimating(过高估计) their intelligence by putting up a good

front. A student who listens attentively and takes notes in class is bound to (一定会) make a favorable

impression on his teachers. But when it comes to exams, he may score near the bottom of the class.

    In a word, you can't judge someone by appearance. The only way to determine a person's intelligence

is to get to know him. Then you can see how he reacts to different situations. The more situations you

see, the better your judgment is likely to be. So take your time. Don't judge a book by its cover.
