Rock-paper-scissors is a game played all around the world. Ever since we were kids. we have relied on it to deal with disagreements with friends——from which channel to watch to who gets to eat the last ice Cream——all because we think the results are completely random.

But are they?

Wang Zhijian, PhD, a professor at Zhejiang University，believes that there is a regulation behind this simple game. So he gathered 360 students, divided them into

groups of six and had each group play 300 rounds of rock-paper-scissors, reported USA Today.

After the first results, Wang thought he was wrong, because players chose each of the three moves about one-third of the time, suggesting that the game is random after all. However, Wang later noticed a surprising regulation of behavior in the data. When players won a round, they usually stuck to the same choice. But when they

lost，they tended to change to a more powerful move. For example, if Player A had

just thrown down scissors to beat Player B's paper，Player A was more likely to throw down scissors again while Player B was likely to choose rock，since rock beats scissors. According to Wang, this might be a function that is called “conditional response”.

So, for the next step of his study, as he told BBC, Wang plans to do some research about how human brains make quick decisions when competing.

Now that you've learned how to predict the moves of your opponent, you’ll have an advantage next time you play rock-paper-scissors with your friends. But there is one problem：make sure they haven’t read about Wang's study, or your advantage

will disappear.

Also, Wang pointed out that his predictions were made depending on the results of the prior round, so when it comes to the very first round, it is always a matter of chance. This means that if you and your friends want to decide something by only one round, the study won’t be much help to you.

does the underlined word “ random” in the first paragraph probably mean?

l (平等的）B. Amusing                            C. Unpredictable    D. Strange

h of the following is TRUE about  Wang Zhijian and his study?

A. He found a new game theory called ”conditional response”.

asked 360 students to play a total of 300 rounds of rock-paper-scissors.

r studying the first several results, Wang discovered the pattern behind the game.

study suggested that the traditional belief that rock-paper-scissors game is random is wrong.

rding to the study, if play A has just used rock to beat Player B’s scissors, then A is more likely to choose   and B is more likely to choose  

；paper  B. rock: scissors  C. scissor; rock  D. paper; scissors

will Wang study about rock-paper-scissors in the future, according to the article?

functions related to the game that are hard-wired into our brains.

B.  How human brains make quick decisions when competing in the game.

C. The psychological behind the players who always win the game.
