【正文】 lia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.根據(jù)第五段中的Fitted with a collisionavoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.可知，配備防碰撞系統(tǒng)，無人機使用激光來探測物體，用測距技術(shù)來探測前方是否有物體，如果探測到物體，無人機就會停下來或者后退，故選A。The production cost of WasteSharks should be reduced.D.C.The importance of ocean protection.（3）What will the WasteShark do with an approaching object? A.s attitudes towards littering.（1）What do we know about the WasteShark? A. A shark moving around the coastline is normally a worrying sight，but this waterborne drone (無人機) threatens floating rubbish instead of people. Our drones are designed to move through a water system, whether it39。It can frighten sharks away.B.Avoid crashing into it.Swallow it.People should take a positive attitude to new technology.【答案】 （1）C（2）C（3）A（4）B 【解析】【分析】本文是一篇說明文，介紹一種水上無人機可以用于清理浮在水面上的垃圾。 （4）考查推理判斷。D.It has helped save thousands of lives.C.根據(jù)第三段中的“Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.”可知，計算機通過檢測紅細胞和白細胞的細微變化來評估血液檢測結(jié)果。 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進行分析，推理，從而選出正確答案。s viewed, is favored by everything from birds to beetles and blossoms to butterflies.catching colors could be used as a cover173。Bees are creatures that are fascinated by sweet things that are iridescentC.Colors unique to animalsD. （2）考查細節(jié)理解。第一段中的“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.”有時，最好的偽裝其實是最耀眼的偽裝，因為研究表明，閃光的金屬彩虹色能在視覺上迷惑捕食者，這讓五顏六色的獵物能夠再存活一天，是全文的主題句，結(jié)合全文內(nèi)容，可知這篇文章主要講了彩虹色有助于生物隱藏，故選B。 In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. 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。 s why you monly find them in crowded streets and parks. 根據(jù)第四段中的“While flying along, they use their sense of smell to find possible targets. They find victims by smelling the carbon dioxide (CO2) breathed out by humans and animals. ”飛的時候，它們用嗅覺發(fā)現(xiàn)目標。根據(jù)最后一段中的“Scientists remend that we use insect repellent and wear lightcolored clothing.”科學家建議我們使用驅(qū)蟲劑或者穿淺顏色的衣服。 【點評】本題考點涉及細節(jié)理解和主旨大意兩個題型的考查，是一篇科研類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進行概括和歸納，從而選出正確答案。s debatable whether that last one there is mon knowledge or not.

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
