And that could mean serious problems for the environment and nations that depend on fisheries (渔业). A new estimate shows that it is 32 million tons higher than count

9、ries have been reporting yearly.The same report notes that the worlds fish catch has been declining since the late 1990s. Countries report their industrial catches to the United Nations Food and Agriculture Organization. But they do not report other kinds of fishing. This includes the catches of sma

10、ll commercial fisheries, which are called artisanal fisheries, and fishing for recreation and individual food.Daniel Pauly at the University of British Columbia in Canada led the study. He noted that a huge amount of some catches is thrown away. “For example, shrimp trawlers (拖网渔船) keep only the shr

11、imp and the fish that they catch often eight to ten times as much as the shrimp gets thrown away.”Pauly told VOA that better estimates of the actual global catch will help ensure there will be enough fish in the future. “But our figures suggest that since 1996 a rapid decrease is happening. And if y

12、ou project this forward you end up in a few decades having much less catch, literally no catch. So that is potentially dangerous.”Researchers also found ways the worlds fisheries are changing. They found that fishing fleets of larger nations are catching fish in the waters of developing countries mo

13、re and more.Pauly said he was surprised by the amount of fishing done by foreign fleets in competition with local fishers. “In West Africa, the figure that was most astonishing is the enormous role of foreign fishing of European and Asian vessels fishing legally or illegally and competing against lo

14、cal fishermen. On the other hand for the US, Australia and some developing countries, such as the Bahamas, what was apparent is the enormous contribution of recreational fisheries, which also never get reported to the FAO.”Researchers say inaccurate data also harms the development and supervision (监

15、管) of effective policy and management measures.语篇解读：世界范围内捕鱼的数量比报告中的数量要多很多，而这些虚假报告对经济和环境都造成了不好的影响。1Whats the main idea of the passage?AFalse amount of fish caught worldwide harms economy environment.BThe worlds fish catch has been declining.CThe global fishing competition is serious.DThe management o

16、f global fishing needs improving.解析：选A主旨大意题。根据文章第一段第一、二句“The amount of fish caught worldwide is much larger than has been reported. And that could mean serious problems for the environment and nations that depend on fisheries(渔业)”可知，本文主要阐述了关于捕鱼数量的虚假报告对环境造成了不好的影响。故选A项。2What does the underlined word “

17、it” (in Para.1) refer to?AThe amount of foreign fishing.BThe amount of local fishing.CThe amount of recreational fishing.DThe amount of all fish caught worldwide.解析：选D代词指代题。it为代词，指代前文，又根据32 million这个数字可推断出it指代第一句中的“The amount of fish caught worldwide”，由此可知选D项。3Which kind of fishing has been reported

18、 to the FAO?AIndustrial fish catches.BCommercial fishing.CFishing for entertainment.DFishing for individual food.解析：选A细节理解题。根据第二段二、三句“Countries report their industrial catches to the United Nations Food and Agriculture Organization. But they do not report other kinds of fishing.”可知，各国向联合国粮食及农业组织报告了他

19、们的工业捕鱼量，但没有报告其他形式的捕鱼数量。故选A项。B(2018合肥高三质检)“The noise made by boats of whale watching tourists may be causing communication problems for the animals，” British researchers said last week.Whale watching is a popular tourist activity in places where groups of killer whales (虎鲸) live.Every day, dozens of

20、boats filled with tourists go to watch the beautiful animals.Unfortunately, the engines of the boats make a lot of noise, and that may be causing problems for the whales, according to a report in the US science magazine Nature.The whales travel in groups, and communicate with each other through soni

21、c calls that some scientists refer to as singing.The sounds of the boat engines may be creating too much background noise for the whales to be able to hear each other.The researchers listened to recordings of whale calls made between 15 and 25 years ago, before whale watching became popular.These we

22、re compared to more recent recordings.They found that the animals have started to sing for longer than they used to, like a person shouting to a friend across a noisy room.It is believed that the whales are trying to communicate hunting or breeding information.Scientists said that, if this is preven

23、ted, the future of the worlds whale population could be in danger. “Animals become slow in mind and repeat themselves in noisy areas，” said Volker Deecke, a Canadian biologist.“They have to say things twice or three times in order to be understood.”The killer whales studied were living off the coast

24、 of northwestern America.The number of killer whales in this area has been falling for several years, but scientists are not sure why.语篇解读：本文首先介绍了观鲸船所产生的噪音对虎鲸的交流造成了困难，然后又介绍了观鲸旅游的盛行和虎鲸的交流方式。4The passage mainly tells us _.Athe problems of whale watchingBhow killer whales communicate with each otherCth

25、e reduced population of killer whales caused by whale watchingDhearing problems of the killer whales caused by whale watching解析：选D主旨大意题。概括文章第一段可得出答案。观鲸船的噪音给虎鲸的信息交流造成了困难。5Now in a noisy background, the killer whales have to _.Asing in a louder voiceBsing longerCtravel in smaller groupsDget nearer to

26、each other解析：选B细节理解题。由第五段可知，因为受噪音干扰，现在虎鲸“唱”的时间比原来长。6Scientists believe that killer whales sing to _.Awarn each other of dangersBkeep in the same groupCsend useful informationDenjoy themselves解析：选C细节理解题。文章倒数第三段有说明，虎鲸“唱歌”是为了交流捕食或繁殖信息。7From the passage, we can feel that the author is _.Aangry BhopefulC

27、worried Ddisappointed解析：选C推理判断题。文章介绍观鲸船的噪音给虎鲸的交流造成了困难，从文章最后的叙述看，虎鲸数量在下降，而科学家也不明白其中原因，因此显然作者对虎鲸的生存状况感到“担忧”。CWhats more exciting than having a fresh hot pizza delivered to your door? How about having it brought to you by a robot? Thanks to Dominos Robotic Unit, that just became a reality. On March 8,

28、the threefoot tall robot made its first delivery to some lucky residents in Brisbane, Australia.The autonomous DRU is the result of a cooperation between Dominos Pizza Australia and Marathon Robotics. The machine can cover a distance of up to 12 miles and back before requiring a battery recharge. Eq

29、uipped with Google Maps and GPS guidance, DRU can go along bike paths and sidewalks and also find the most efficient way to its destination. LIDAR, a laserbased sensor technology similar to the one used in selfdriving cars, enables DRU to detect and avoid obstacles, while traditional sensors ensure

30、its path to its destination is safe. DRUs plastic shell protects the food from the bad weather, while its aluminum and steel container ensures that the pies remain hot.The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders. To access their food, customers ha

31、ve to enter the unique code provided by the company. This not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.Dominos expects additional DRU to be ready for service in its various Queensland locations within the next six months. But dont expect these super cute robots to replace humans anytime soon. According to Dominos, the DRU still needs much testing, which the company believes could take up to two years. There is also the issue of regulations. The public use of autonomo
