themselves Bees work hard, and they are smart enough to learn something. Researchers found a group of bees and taught them to tell which horizontal line(k psx) was higher than the other. If they could find the higher line, they would get sugar as a prize. After training for a period of time, the researchers tested the bees. To their surprise, the bees found the higher orizontal line quickly and got sugar. Instead, when the researchers showed them vertical lines(EH s), the bees simply flew away, because they knew there was no way to get sug Chimpanzees(# E1E)are very human-like. They can learn fast and well. Researchers howed the numbers from one to nine on the screen. Chimpanzees and some college students were asked to remember where the numbers were after watching the numbers in less than a second. The adult chimpanzees and the college students performed almost the same, but the young chimpanzees performed much better. It was amazing In the test, the dolphins A. felt afraid and ran away from the mirror B. tried to fight with the ones in the mirror C. didn't find any red marks on their bodies D. tried to clean the red marks off their bodies 2. When the bees saw the vertical lines, they A flew away B. found the higher line C. stayed there D. found the numbers 3. performed better in remembering where the numbers were A. The adult chimpanzees B. The old chimpanzee C The young chimpanzees D. The college students4 themselves. Bees work hard, and they are smart enough to learn something.
