Leaf growth in two plants increased by 20 percent, while leaf growth on a third plant increased by 14 percent. Scientists conducted the study on tobacco plants. But they think the genetic changes will produce the same results in corn and rice. （1）What will happen to the plants when scientists change plants39。s protective system to lightadjusting glasses. When a person wears the glasses outside during the day, the lenses（鏡片）darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food. s protective system. Normally, this system is activated when a plant gets too much sunlight, said scientist Krishna Niyogi, coauthor of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow. s genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent. s genes in order to make it use sunlight more quickly. Someday, the results could increase the amount of food produced around the world. （4）考查主旨大意。 （3）考查推理判斷。t a new one.”引人注目的顏色可以用來偽裝，這種想法并不新鮮，排除C，故選D。根據(jù)第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被動物用來通過逃離捕食者而活得更久，排除A；根據(jù)第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在這里我想指出的是，在某些物種中，尤其是那些表現(xiàn)出強(qiáng)烈兩性差異的物種，比如天堂鳥、孔雀，甚至在某些蝴蝶或魚類中，彩虹色的出現(xiàn)很可能是由性別選擇所驅(qū)動的。Metallic iridescent as the best disguiseC.A famous camouflage strategyWhether there are any differences between bees and birds.B.Bees can always tell the difference between a circle and an ovalB.catch the attention of their matesC.s173。s concealment？ Coloration in the Animal Kingdom, already in 1909, that 39。 The idea that eye173。 And in our research group we are of course interested in why this vivid metallic color is so widespread in nature. Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates.

But numerical cognition, such as exact number and arithmetic operations, requires a more plex level of processing.”許多物種都能理解數(shù)量之間的差異，并以此來尋找食物、做出決定和解決問題。根據(jù)第五段中的“If math doesn39?！笨芍琑MIT大學(xué) 的此前的研究表明，一些靈長類動物、鳥類、嬰兒甚至蜘蛛都可以加減法。A Discovery About the Tiny Brain of BeesB.Bees can recogize the exact number.B.requires addition and subtraction two plex processingB.Longterm rules and short term working memory.C.t require a massive brain, there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer.
