ormation from being disturbed.(3)Why did the researchers study the device according to Yingying Chen? A.It uses antennas to pick up networks39。It saves people in danger of natural disasters.B.The benefit of the study findings.(2)What39。The principle the study is based on.B. The peerreviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online. Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes, researchers said.(1)What does paragraph 3 talk about? A.s hard to set up expensive screening equipment like what39。 It uses channel state information (CSI) that is readily available in lowcost WiFi devices. This could have a great impact on protecting the public from dangerous objects, said Yingying Chen, a coauthor of the study, There39。 The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干擾)caused by two factors of objectsthe material and shape. Most dangerous objects such as weapons are usually metal or liquid, which have significant interference, researchers said. A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them. These items could include weapons, chemicals, laptops and batteries for bombs, the research team said on Tuesday. 【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,是一篇環(huán)境類閱讀,考生需要準確掌握細節(jié)信息,同時根據(jù)上下文的邏輯關(guān)系,進行分析,推理,從而選出正確答案。根據(jù)最后一段中的“…At the current rate, the world39。根據(jù)第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.”到達一個新發(fā)現(xiàn)的在拉森冰架下面隱藏了12萬年的的生態(tài)系統(tǒng),可知選D。故選C。 (2)考查詞義猜測。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)。冰山下面顯現(xiàn)的新的海洋生態(tài)系統(tǒng)為科學(xué)家提供了研究未知的海洋生物的機會。Many creatures living in deep water will die out due to climate change.D.There is no need to worry about climate change in Antarctica.B.It will disappear in a very short time.D.It is as big as London.B.The A68 iceberg with the ecosystem beneath it.D.The Larsen C ice shelf.B.To explore a new way to prevent climate change.D.To study how the iceberg was formed.B. There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, At the current rate, the world39。 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。 Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge icebergA68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission. A team of international scientists is due to set off for the world39。最新高三英語閱讀理解(科普環(huán)保)各地方試卷集合匯編一、高中英語閱讀理解科普環(huán)保類1.犇犇閱讀下列短文,從每題所給的A、B、C和D四個選項中,選出最佳選項。 s biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf. The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change, she said. It is important that we get there quickly before the undersea environment changes as sunlight enters the water.s lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die.s ocean will be, on average, at least 60cm higher by the end of the century. However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.(1)Why are the scientists eager to go to the iceberg? A.To study a newly discovered ecosystem.C.To explore the geography of the Larsen C ice shelf.(2)What do the underlined words this one in the fourth paragraph refer to? A.Climate change in Antarctica.C.The condition of animal species in Antarctica.(3)What can we learn about the A68 iceberg from the text? A.It is part of an ice shelf in the Arctic.C.It has uncovered an unknown ecosystem in Antarctica.(4)What can we infer from the last paragraph? A.The ice sheets in Greenland and Antarctica are melting at a steady rate.C.By 2100, the sea level will have risen to a much higher level than now.【答案】 (1)B(2)C(3)D(4)D 【解析】【分析】本文是一篇說明文,南極地區(qū)的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。 (1)考查細節(jié)理解。故選B。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)。 (3)考查細節(jié)理解。 (4)考查推理判斷。s oceans will be, on average, at least 60cm higher by the end of the century.”按目前的速度,世界的海洋到本世紀末平均至少升高60厘米,選D。2.犇犇閱讀理解 Research suggested that WiFi can now be used to estimat
