A group of genes, volatile sulfur pounds (含硫化合物), became very active in the fruit, and they were found responsible for resulting in the unpleasant smell.”可知，研究人員找到一組基因——揮發(fā)性硫化合物（SouthType），在水果中非常活躍，發(fā)現(xiàn)是它們導(dǎo)致了這種難聞的氣味。The Mystery of the Unpleasant Smell of Durian【答案】（1）D（2）A（3）C（4）D 【解析】【分析】本文是一篇說明文，新加坡的研究者找出導(dǎo)致水果有難聞氣味的原因就是水果中含有的揮發(fā)性硫化合物非?；钴S，這種氣味對于野外生存榴蓮來說有利于吸引動物來吃這種水果，同時傳播種子。The Distribution of DurianB.What39。Durian has no relationship with the cacao tree.（4）What39。Some of durian species can not be eaten.B.Tolerated.（3）What can we infer from the text? A.C.Escaped.Volatile sulfur pounds.（2）What does the underlined word “evolved” in Paragraph 5 probably mean? A.Rotten ingredients in it.B. Despite the striking smell, many people actually enjoy eating the fruit. However, not all durian species are edible, and some of them may even cause damage to our health, Even so, the fruit is often imported, significantly contributing to the economy.（1）What give durian its unique smell? A. However, this smell might be an advantage for durian in the wild. Although we find it unpleasant, many animals might be attracted by it. If they eat the fruit, then they can easily spread its seeds everywhere, thus contributing to the distribution of the species. Durian is wellknown throughout Southeast Asia as the king of fruits, mostly because of its awful appearance and smell. However, the origin of this unpleasant smell was unknown, so researchers decided to map the genome of the fruit, and find the gene that controlled it. A group of genes, volatile sulfur pounds (含硫化合物), became very active in the fruit, and they were found responsible for resulting in the unpleasant smell.最新高考英語一輪復(fù)習(xí) 專項訓(xùn)練 閱讀理解一、高中英語閱讀理解1．閱讀理解 Durian(榴蓮) is probably the smelliest fruit in the world, letting out an unusual unpleasant smell which would make anyone bring up. However, nobody was aware of what gave this fruit its unique smell, so a team of researchers from Singapore decided to take a look at its genome (基因組) and find out, The fruit confuses everyone with a sulfuric smell, like rotten onions and ingredients. The smell lasts long, mostly because the fruit contains more volatile sulfur pounds. Other species usually benefit from two gene copies at most, but durian has four, leading to the striking smell. The mapping of the durian genome also showed some other information on the species. First of all, the fruit has an impressive number of genes, namely 46,000. Also, with the help of these genes, they saw how it evolved, and discovered it was related to the cacao tree. All the other discoveries have been published in the journal Nature Genetics.Onions nearby.Two gene copies.C.D.Developed.B.Predicted.D.No birds enjoy eating durian.Durian can be planted all over the world.C.D.s the best title for the text?
