A.B. In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition. Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish. As for making use of this method for hiding in plain sight, Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize. The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird39。t a new one. The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing173。根據(jù)第三段中的“The argument goes that famers eat more cooked food and more dairy than hunter gatherers.”可知農(nóng)民比狩獵采集者吃更多的熟食和奶制品,即農(nóng)民們發(fā)f和v音的原因是他們喜歡吃更多的熟食。同時這也強調(diào)了人類特有的一切都是物質(zhì)和精神的結(jié)合:語言必須把聲音和意義結(jié)合起來,沒有真實的物體,意義就不可能存在或傳播。C.. A.根據(jù)最后一段中的“…At the current rate, the world39。根據(jù)第二段中的“Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light.”可知,科學(xué)家著急趕去世界最大的冰山是為了在其受到光照影響之前研究這座冰山下面的海洋生態(tài)系統(tǒng)。It will disappear in a very short time.D.To explore a new way to prevent climate change.D. Professor David Vaughan, science director at the BAs, said, We need to be bold (大膽的) on this one. Larsen C is a long way south and there39。 Climate change in Antarctica.C.The ice sheets in Greenland and Antarctica are melting at a steady rate.C.根據(jù)第三段中的“The calving of A68 provides us with a unique opportunity to study marine life...”可知A68冰山的形成為科學(xué)家提供了研究海洋生物的獨一無二的機會,所以Professor David Vaughan認為科學(xué)家要果敢地抓住這次機會,故this one指的是A68冰山和它下面的生態(tài)系統(tǒng)。2.犇犇閱讀理解 rather than of the arrangement of our teeth. In reality, though, any given language must be both.t exist or be transmitted without a real object. But neither can it be reduced to the purely physical, as our inability to understand or even to recognise foreign languages makes clear. The food we eat shapes our jaws, and our jaws in turn shape the sounds of our language. The ease with which we eat probably shapes our thought too, as anyone who has suffered toothache could testify. What we eat may have shaped the sounds of our language, but how we eat changes how we feel and what we use language to express. A family meal is very different from a sandwich at the office desk, even if the calorie is the same. Food has purposes and meanings far beyond keeping us alive and pleasing the Palate (味覺).(1)Compared with adults, babies could more easily understand the Greek languageD.Food and thinking.(3)The reason for farmers39。biting more with front teethC.jaws help shape our thoughtB.

This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢體). This makes coordinating (協(xié)調(diào)) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do.Ways in which bats move differently from birds.(2)Which of the following is a false assumption about bats that was recently corrected? A.Bats might hurt themselves when landing.綜上所述,可知,蝙蝠與鳥運動方式的不同是本文的主題。 (4)考查推斷判斷。 Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has bee an annual publichealth emergency despite government vows to solve the problem.由此可判斷出政府幾乎沒有保護其公民免受嚴重污染。根據(jù)第五段中的“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states.”本句是說新德里每年都籠罩在污染中。故選B。 The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模擬)10w, medium, and highaltitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel.
