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.【英語】高考英語高中英語閱讀理解(科普環(huán)保)(一)解題方法和技巧及練習(xí)題一、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(cè)物體，用測(cè)距技術(shù)來探測(cè)前方是否有物體，如果探測(cè)到物體，無人機(jī)就會(huì)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．犇犇閱讀理解 Tests in humans could begin in months. But even if these go well, a licensed vaccine for widespread use to protect those at most risk 173。 would still be years away, experts advise. Zika has been spreading across Central and South America and, most recently, Africa. More than 60 countries and territories now have continuing transmission(傳播) of the disease, which is carried by mosquitoes. The virus causes serious birth damages during pregnancy and has been declared a global public health emergency. Researchers say they will push ahead with developing the needed virus vaccine. There are many existing vaccines for other disease that use this type of technology, while there are relatively few DNA173。. A.pregnant women in Africa will be the first to benefit from the vaccine.C.The Zika virus will cause less serious birth defects during pregnancy in months.（2）Which of the following statements is NOT true? A.US scientists have tested more than two types of Zika vaccine in mice.C.It is still unknown whether the vaccine is safe and effective.（3）Which can be the best title for the passage? A.works very well39。Zika vaccine still has a long way to goC.More attention has been paid to Zika vaccine【答案】 （1）C（2）B（3）A 【解析】【分析】本文是一篇說明文，介紹了科學(xué)家發(fā)現(xiàn)一種實(shí)驗(yàn)性疫苗可以保護(hù)小鼠免受寨卡病毒侵襲。根據(jù)第二段中的But even if these go well, a licensed vaccine for widespread use to protect those at most risk 173。 would still be years away可知，但是，即使這些進(jìn)展順利，一種廣泛用于保護(hù)高危人群的授權(quán)疫苗仍需數(shù)年時(shí)間，也就是說如果人體試驗(yàn)進(jìn)展順利的話，短期內(nèi)仍無法獲得授權(quán)疫苗，故選C。根據(jù)第三段中的US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice可知，美國科學(xué)家在白鼠身上只測(cè)試了兩種而不是兩種以上的寨卡病毒，故選B。根據(jù)第一段中的A single dose(劑量) of an experimental vaccine(疫苗) can protect mice against the Zika(寨卡) virus,可知，一種實(shí)驗(yàn)性疫苗可以保護(hù)小鼠免受寨卡病毒侵襲，由此可知，本文主要介紹的是寨卡病毒疫苗對(duì)小白鼠非常有效，故選A。3．犇犇閱讀下列短文，從每題所給的A、B、C和D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。 One spring day, once the flowers have begun to open, a bee will hover (盤旋) and zip through your yard and divebomb your piic table. While you39。 A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, strawlike tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her coworkers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be p
