Is it worth the wait? Yes, I assure you it is. Once inside, visitors find a long, dark room with a high ceiling. A single bright light shines through heavy rain falling around visitors. The mist. The damp air. The noise. It feels like a mighty storm is pouring down. But the storm is inside. And visitors aren't getting wet. Instead, visitors wander in awe, admiring the rain and the artists who created it. The Rain Room was created to highlight the connection between humans, nature and technology. With a tracking system that senses movement and stops the rain wherever visitors move, it does just that. Light and sound produce an experience that feels both natural and foreign. The exhibit is moving on to Atlanta next month. I urge you to visit before then. It's time to experience the Rain Room for yourself! Welcome to the Rain Room ·The Rain Room features falling water. Please be aware you may get slightly wet. However, visitors wearing raincoats will be turned away. ·This exhibit features advanced technology. To ensure its effectiveness, please avoid wearing dark or reflective clothing. · Visitors are welcome to take photographs of the exhibit. ·Children must be accompanied by an adult. ·For the convenience of all guests, visits are limited to 10 minutes. 语篇解读：本文是一篇应用文。文章通过介绍 the Rain Room 的 景象、设计理念、特色以及参观时的注意事项来吸引游客去参观这一 艺术展。 1．What's the purpose of the text?

A．To keep visitors from getting wet. B．To protect the exhibit from water damage. C．To time how long visitors are in the room. D．To count the number of visitors in the room. 解析：选 A　推理判断题。根据第二段第二句“With a tracking system that senses movement and stops the rain wherever visitors move, it does just that.”可推知，这个追踪系统能够保 证游客不被雨水淋湿。故选 A。 3．What must you do when visiting the Rain Room? A．Wear a raincoat. B．Wear dark clothing. C．Leave your camera outside.

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 countries have been reporting yearly. The same report notes that the world's 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 small 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 shrimp 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 you 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 world's fisheries are changing. They found that fishing fleets of larger nations are catching fish in the waters of developing countries more 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 local 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。 4．What's the main idea of the passage? A．False amount of fish caught worldwide harms economy environment. B．The world's fish catch has been declining. C．The global fishing competition is serious. D．The management of 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。 5．What does the underlined word “it” (in Para.1) refer to? A．The amount of foreign fishing. B．The amount of local fishing. C．The amount of recreational fishing. D．The 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。 6．Which kind of fishing has been reported to the FAO? A．Industrial fish catches. B．Commercial fishing. C．Fishing for entertainment. D．Fishing 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。 7．Which part is this article possibly chosen from on the Internet? A．Health report.　　　　 B．Science in the news. C．Explorations. D．Technology report. 解析：选 B　文章出处题。根据文章第四段第一句“Pauly told VOA that better estimates of the actual global catch will help ensure there will be enough fish in the future.”可知，保利在接 受“美国之音”的采访时说了些话，由此可推断出这是一则新闻，故 选 B 项。 C (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 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 sonic 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 were 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 prevented, the future of the world's 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 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。 8．The passage mainly tells us ________. A．the problems of whale watching B．how killer whales communicate with each other C．the reduced population of killer whales caused by whale watching D．hearing 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。 9．Now in a noisy background, the killer whales have to ________. A．sing in a louder voice B．sing longer C．travel in smaller groups D．get nearer to 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。 10．From the passage, we can feel that the author is ________. A．angry　　　　　　 B．hopeful C．worried D．disappointed 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”。
