I knew my friend was up to something. “OK ,” I said casually, trying to hide my curiosity. We walked along in silence for a few minutes until we went into the jungle. The temperature dropped instantly. There were no pathways, but it was clear that someone had passed through recently. “We need to be really quiet .” Decha warned suddenly. “We don’t want to frighten them.” He shifted a bag that I hadn’t even noticed onto h is shoulder. My heart was beating wildly. Eventually, we stopped at a pile of fallen leaves. Inside the pile, four small furry bodies lay there with their mouths wide open.

Unfriendly C Scientists have been studying how people use money for long. Now they’ re finding some theories may apply to one group of monkeys. Researchers recently taught six monkeys how to use money. They gave the monkeys small metal disks（圓片） that could be used like cash and showed them some yummy apple pieces. The monkeys soon figured out that if they gave one of the disks to a scientist, they’ d receive a piece of apple in return. If you think that is all the monkeys can figure out, you are wrong. Two researchers, Jake and Allison, acted as apple sellers in the experiments. The monkeys were tested one at a time and had 12 disks to spend in each experiment. Jake always showed the monkeys one apple piece, while Allison always showed two pieces. But that’ s not necessarily what they gave the monkeys. The number of apple pieces given for a disk was determined at random. Experiment One: Allison showed two pieces of apples but gave both piece only half the time. The other half, she took one piece away and gave the monkey just the remaining piece. Jake, on the other hand, always gave exactly what he showed: one piece for each disk. The monkeys chose to trade more with Allison. Experiment Two: Allison continued to sometimes gave two pieces and sometimes one piece. But now, half the time, Jake gave the one apple piece he was showing, and half the time he added a bonus. Guess what? The monkeys chose to trade more with Jake. In the first experiment, the monkeys correctly figured out that if they traded with Allison, they’ d end up with more treats. In the second one, when a monkey received two pieces from Jake, it seemed like a gain. When Allison gave the monkey only one piece instead of the two she showed, it seemed like a loss. The monkeys preferred trading with Jake because they’ d rather take a chance of seeming to win than seeming to lose. We also sometimes make silly business decisions just to avoid the feeling that we’ re getting less, even when we’ re not. Would you have made the same choices? 28. What conclusion might experts draw from the first experiment? A. People are smarter in terms of finance. B. It’ s easy to teach monkeys how to trade. C. Business theories can apply to all monkeys. D. The monkeys show certain business sense. 29. What does “ a bonus” in paragraph 5 refer to? A. A coin. B. A chance. C. A metal disk. D. An apple piece. 30. Why did the monkeys choose to trade more with Jake in the second experiment? A. Because they didn’ t like the feeling of losing. B. Because they get more apple pieces from Jake. C. Because Jake always gave them two apple pieces. D. Because the apple pieces from Jake were yummy. 31. What could be the best title for the passage? A. Disk for Apple: Who to Trade with? B. Shopping for Bargain: Same or different? C. Moneky’ s Business Sense: Smart or Silly? D. People’ s Business Decision: Lose or Gain? D Japanese researchers made a botanical announceme
