Our drones are designed to move through a water system, whether it39。 Dubaibased operator Ecocoast has two WasteShark drones. Cofounder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast39。It can frighten sharks away.B.The causes of ocean pollution.B.Avoid crashing into it.Break it into pieces.Swallow it.Fly over it.（4）Which of the following ideas does Liparts agree with? A.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。根據(jù)第四段中的“By 2016 there were approximately 150 million tons of plastic in the world39。 （4）考查推理判斷。 【點評】本題考點涉及細節(jié)理解，推理判斷和段落大意三個題型的考查，是一篇科教類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。 This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.lead to a longer fire seasonD.snow on the ground mirrors more sunlight back into spaceD.suggest that people should take measures to protect the environmentD.B.createdwarm the climate as the supposition goesB. （1）考查細節(jié)理解。根據(jù)第四段中的“The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.”可知地上的雪反射陽光這是大火的間接的影響，是在第二年春天的時候發(fā)生的事情，并不是immediate effects。 （4）考查推理判斷。根據(jù)第一段中的“scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.”可知從這個研究中得到的結(jié)論是B。 The technology is the brainchild of Dr Vishal Nangalia, 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.fortspot cases.C.To show the influence of AI.B.It helps patients recover earlier.B. （1）考查詞義猜測。 （2）考查細節(jié)理解。根據(jù)第二段中的I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a pletely new example in the way we manage healthcare. 楊教授認為，人工智能在醫(yī)療保健領(lǐng)域的潛力與工業(yè)革命一樣大，以此類比，說明人工智能在醫(yī)療領(lǐng)域的影響力。故選C。 Vulture (禿鴛)s eyes and face.t move any more than a human statue until the threat has passed. Sea Hare (海兔)s not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smellrelated defense that is almost the opposite of its smelly panions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.t know how appealing it is.（1）The sea hare defends itself from predators by ________. A.giving off smelly gas to try to drive predators away（2）Which of the following statements is TRUE according to the passage? A.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.B.C.D.Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質(zhì)使得捕食者對食物不那么感興趣，從而保護自己免受捕食者的傷害。Opossum (負鼠)部分中的“In order to bee ‘dead’, they don39。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團。故選C。s (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shakeup yet.s measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常數(shù)).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.（1）What does Paragraph 1 mainly tell us? went before libra in me
