A. “This is a world issue, and it requires everyone to work together,” Mars spokesperson Barry Parkin told Business Insider. In the meantime, US pany Mars, one of the world39。s author, wrote. “In other words, as higher temperatures squeeze more water out of soil and plants, it39。t lie in increased heat, however，but in lower humidity (濕度)，as it39。s predicted that by 2050, climate change will have accelerated the rate at which temperatures in these countries rise, making it extremely difficult for cacao to grow there.

But if a heat wave and a severe drought （干旱）were to hit at the same time and the groundwater was exhausted, the trees may not be so lucky, Drake says.”可知，這些樹擅長吸取地下水，如果熱浪干旱同時發(fā)生，地下水枯竭的話，那么這些樹生存的可能性就比較小了。劃線部分意思應(yīng)當(dāng)接近于“大大減少，降低”這一類的意思cease意為“停止”，故選D。由第四段后面的內(nèi)容可知，令研究者們驚訝的是，面對著人工制造出來的熱浪，這些樹繼續(xù)以接近正常的水平蒸發(fā)，有效地使自己和周圍的環(huán)境涼爽下來。(3)考查詞義猜測。根據(jù)第三段中的“Ecologist John Drake… and his colleagues grew a dozen Parramatta red gum … trees in large, climatecontrolled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia.”可知，研究者們將12棵紅桉樹種植在巨大的，氣候受控制的塑料艙里，這種塑料倉將這些樹和周圍的森林分離開來。sweat’”可知，桉樹通過“流汗”，即釋放水分來抵抗極度的熱，故選A。(1)考查細(xì)節(jié)理解。D.No further experiments will be done other species.C.Photosynthesis is necessary for the trees to sweat.D.C.B. conditions in their natural environment.（3）The underlined phrase “ground to a near halt” in Paragraph 4 means “________”.

The trees grown in warmer conditions coped just as well as the others, and photosynthesis rates bounced back to normal after the heat wave passed, Drake and his colleagues reported online in Global Change Biology. Ecologist John Drake of the . College of Environmental Science and Forestry and his colleagues grew a dozen Parramatta red gum (Eucalyptus parramattensis) trees in large, climatecontrolled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia. Six of the trees were grown at surrounding air temperatures and six at temperatures three degrees Celsius higher. The researchers withheld (扣留) water from the surface soil of all 12 trees for a month to imitate a mild dry spell, then induced a fourday “extreme” heat wave: They raised the maximum temperatures in half of the pods（three with surrounding temperatures and three of the warmer ones）— to 44 degrees ℃. As plants change sunlight into food, or photosynthesize (光合作用), they absorb carbon dioxide through pores on their leaves. These pores also release water via transpiration(蒸騰), which circulates nutrients through the plant and helps cool it by evaporation(蒸發(fā)). But exceptionally high temperatures are known to greatly reduce photosynthesis—and most existing plant models suggest this should also decrease transpiration, leaving trees in danger of fatally overheating. Because it is difficult for scientists to control and vary trees39。7．閱讀理解由此可知，本文最好的題目應(yīng)該是“榴蓮難聞之謎”最為適合，故選D。新加坡的研究者決定來查明原因。(4)考查主旨大意。根據(jù)最后一段中的“not all durian species are edible, and some of them may even cause to our health,”可知，并不是所有的榴蓮都是能吃的，有些榴蓮是不可以吃的。故選A。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)榴蓮與可可樹有關(guān)。根據(jù)倒數(shù)第二段內(nèi)容可知，研究者畫出了榴蓮的基因圖。故選D。(1)考查細(xì)節(jié)理解。D.The Influence of the SmellC.s Durian?s the best title for the text? A.D.Durian can be planted all over the world.C.No birds enjoy eating durian.D.Predicted.B.Developed.D.Two gene copies.C.Onions nearby. 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. 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. 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, 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和主旨大意三個題型的考查，是一篇科技類閱讀，考生需要準(zhǔn)確掌握細(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 new camera, called Clips, is a small, smart device.”可知，本文主要講述了谷歌開發(fā)的一款新的照相機(jī)，并對照相機(jī)的各種功能和使用進(jìn)行了介紹。 （4）考查主旨大意。re likely to get more assistance from the artificial intelligence packed into our apps and gadgets”可知，這款相機(jī)依靠先進(jìn)的科技和人工智能等使得它成為了可能，成為了可以幫
