【正文】 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. 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.D.Durian can be planted all over the world.C.The Influence of the SmellC.D.在這些基因的幫助下，他們了解了榴蓮的基因如何演變的，并發(fā)現(xiàn)榴蓮與可可樹(shù)有關(guān)。新加坡的研究者決定來(lái)查明原因。s past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of mon flies in it, record two interglacial periods(間冰期)in northwest Greenland.s ice sheet might respond to manmade global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world, said Yarrow Axford, an associate professor in the team. One of the big uncertainties in climate science is how fast the Earth changes when it gets warmer. Geology gives us an opportunity to see what happened when the Earth was warmer than today, said Axford.根據(jù)第一段中的“The mud, and remains of mon flies in it, record two interglacial periods（間冰期）in northwest Greenland.”在格陵蘭島西北部，泥漿和常見(jiàn)蒼蠅的殘骸記錄了兩次間冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”盡管研究人員很早就知道這兩個(gè)時(shí)期——全新世早期和最后一次間冰期——在北極經(jīng)歷了變暖，但混合的蠅類表明格陵蘭島甚至比之前認(rèn)為的還要熱。根據(jù)第三段中的“After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’” 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。s language has decreased over the past century. Currently there are two apps, called Learning Tlingit and Tlingit Language Games. The Learning Tlingit app serves as a language guide. It provides Tlingit words and expressions, the tribal alphabet, as well as a basic list of the words included. With the Tlingit Language Games app, users are given a choice of different places of environments, like a house, forest or ocean.（1）What is the problem the native Americans are facing now? number of native Americans has been increasing. and fewer native Americans speak their own language. native language has been extinct.39。根據(jù)第六段中的“However, fearing a loss of history and culture, the Indian Nations are experimenting with new ways to increase the language ability of tribal members.”然而，害怕失去自己的 （4）考查主旨大意。 A study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain.
