A.Swallow it.Break it into pieces.Avoid crashing into it.The severity of ocean garbage pollution.D.The causes of ocean pollution.B.It is a rubbish collector.D.It can frighten sharks away.B.t have a onesizefitsall solution and requires a bination of new technology, preventative measures and changing people39。 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。 Our drones are designed to move through a water system, whether it39。s oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat. According to RanMarine, the WasteShark is available in both autonomous and remotecontrolled models. Measuring just over five feet by threeandahalf feet ( meters by meter), it can carry up to 352 pounds of rubbish ( kg) and has an operational battery life of 16 hours. A shark moving around the coastline is normally a worrying sight，but this waterborne drone (無人機(jī)) threatens floating rubbish instead of people.高三英語閱讀理解(科普環(huán)保)技巧小結(jié)及練習(xí)題及解析一、高中英語閱讀理解科普環(huán)保類1．犇犇閱讀短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。 Developed by Dutch pany RanMarine, the WasteShark takes nature as its inspiration with its whale sharklike mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast. By 2016 there were approximately 150 million tons of plastic in the world39。 WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines, said Oliver Cunningham, one of the cofounders of RanMarine. 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.s around the perimeter (周邊) or through the city itself. The drones are that last line of defense between the city and the open ocean, added Cunningham. WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remotecontrolled model and just under $ 23, 000 for the autonomous model. intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn39。s attitudes towards littering.（1）What do we know about the WasteShark? A.It is an ocean explorer.C.It can catch fish instead of people.（2）What does Paragraph 4 mainly tell us? A.The dangers of using plastics.C.The importance of ocean protection.（3）What will the WasteShark do with an approaching object? A.B.C.D.The WasteShark should be used more widely.B.The production cost of WasteSharks should be reduced.D. （1）考查細(xì)節(jié)理解。 （2）考查段落大意。s oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat.”可知，預(yù)計(jì)到2016年，估計(jì)約有25萬噸垃圾漂浮在海洋上，故可知，本段主要講述海洋垃圾的嚴(yán)重性，故選C。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(jī)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(jī)就會停下來或者后退，故選A。根據(jù)最后一段中的“However, Liparts argues that cleaning waterways doesn39。s attitudes towards littering.”可知，這種無人機(jī)并非解決水上垃圾污染的萬全之策，需要多措并舉，才能達(dá)到目的，故選B。2．犇犇閱讀下列短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。 Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space. This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat. We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere. Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, watts per square meter of area burned are soaked up by the earth from greenhouse gases, but watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.（1）According to the new findings, taking steps to prevent northern forest fires may ________. A.cause the forest fires to occur more frequentlyC.protect the forests and the environment there（2）The following are all the immediate effects after a forest fire EXCEPT ________. A.the levels of ozone which is a type of oxygen increaseC.ashes from the fire fall on the ice surface and take in more radiation from the sun（3）Earlier studies about no
