It is said that elephants can get drunk by eating the fermented (发酵) fruit rotting on the ground. Books have even been written to prove the truth of the phenomenon. But a study published in the journal Physiological and Biochemical Zoology tells a very different story. Steve Morris, a biologist at the University of Bristol in England and an author of the study, says there is nothing in the biology of either the African elephant or the marula fruit to support the stories. Morris says, “ people just want to believe in drunken elephants.”The marula tree, a member of the same family as the mango, grows widely in Africa. Its sweet, yellow fruit is used for making jam, wine and beer. “The first mistake of the drunken-elephant theory is that its unlikely that an elephant would eat the fruit if it were rotten, ” Morris says. “Elephants eat the fruit right off the tree, not when its rotten on the ground, ” he explains. Other experts add that if an elephant were to eat the fruit on the ground, it wouldnt wait for the fruit to ferment. Michelle Gadd, an African wildlife specialist, says that elephants and many other animals, including birds and monkeys, are too fond of marula fruit to let it rot. If fermented fruit on the ground is out of the question, so is the notion that the fruit could ferment in the stomach of elephants, according to the study authors. Food takes between 12 and 46 hours to pass through an elephants digestive system, the authors point out, which is not enough for the fruit to ferment. Supposing that this happened, its still highly improbable that the food would produce enough alcohol to make an elephant drunk. Through calculations of body weight, elephant digestion rates, and other factors, the authors conclude that it would take about 1.9 litres of ethanol(乙醇) to make an elephant drunk.56. We can learn from the passage that _. A. it is not easy to find marula fruit in the wild in Africa B. African elephants dont like to eat marula fruit at all C. marula fruit can be made into food or drink consumed by people D. birds and monkeys in Africa like to eat rotten marula fruit 57. According to Paragraph 6, marula fruit is likely to ferment _.
