There are several companies on Oahu and the Big Island that offer a swim with these animals in the wild.

By 2048, to be exact, catches of all the presently fished seafoods will have decreased on average by more than 90 percent since 1950. The study says the loss of biodiversity (生物多样性) cuts down the ability of oceans to feed the worlds growing human population expected to rise by 50 percent to nine billion in 2050. Overfishing also destroys the stability of ocean environments largely, reducing the oceans ability to produce seafood, resist diseases, filter (过滤) pollutants and rebound (回升) from stresses such as climate change. And every species matters when it comes to the oceans ability to repair itself, says the study.Dr. Boris Worm, of Dalhousie University, Nova Scotia, the lead author, said, “This is what is projected, not predicted, to happen. I am confident we will not go there because we will do something about it. But if this trend continues in this predictable fashion, as it has for the last 50 years, the worlds currently fished seafoods will have reached what we define (定义) as collapse by 2048.”“Every year a higher percentage of the currently fished stocks collapse. We are losing it piece by piece.” Prof Callum Roberts, of the University of York, who was not involved in the study, said, “The animals and plants that inhabit the sea are not merely embellishments (装饰) to be wondered at. They are essential to the health of the oceans and wellbeing of human society. We need to ban destructive fishing practices and create a network of largescale marine reserves around not just Britain, but globally. ”语篇解读：本文阐释了过度捕捞给整个海洋环境造成危害，并呼吁在全球范围内禁止过度捕捞，建立保护网络。5According to the passage that all seafood will run out in 2050 will _.Amake the sea water much fresher and cleanerBmake it impossible to support more people with the seafoodCmake the whole animals on land die awayDmake the fishermen have more free time to rest解析：选B由第一段中的“The study says the loss of biodiversity (生物多样性) cuts down the ability of oceans to feed the worlds growing human population expected to rise by 50 percent to nine billion in 2050.”可知，过度捕捞造成的生物多样性消失最终将使海洋养活不了增长的世界人口。6What bad result will overfishing bring to us?ADestroying the stability of ocean environments.BLargely reducing the oceans ability to produce fresh water.CIncreasing the oceans ability to filter pollutants.DMaking the ocean have no more capability to repair itself.解析：选A由第二段中的“Overfishing also destroys the stability of ocean environments largely，reducing the oceans ability .”可知过度捕捞会破坏海洋环境的稳定性。7What is Dr. Boris Worms idea about the future of the seafood in the world?AAll seafood will surely run out in 2050.BThe seafood will become more than now in 2050.CSeafoods will not have collapsed if people try their best to protect the ocean.DThe situation of the seafoods will get much worse than predicted even if people do something about it.解析：选C由第三段中的“I am confident we will not go there because we will do something about it.”可判断C项正确。8How should we do in order to protect the seafood from running out?AWe should encourage the destructive fishing practices around the world.BWe should regard the animals and plants that inhabit the sea embellishments to be wondered at.CWe should create a network of largerange sea reserves around the whole world.DWe should learn that the animals and plants that inhabit the sea are not necessary to the health of the oceans.解析：选C由最后一段最后一句“We need to ban destructive fishing practices and create a network of largescale marine reserves around not just Britain，but globally.”可知，Callum Roberts教授提出了两个解决办法，C项与第二个办法吻合。CTheres a new viral music video on the Internet thats getting millions of people dancing and laughing. Psy is a singer who created Gagnam Style, a music video which featured a catchy tune and interesting dance.The new music video called The Fox (What does the fox say？) has recently gone viral. At 123,000,000 views, it may even catch up to Gagnam Style. The video asks the question, “What does the fox say？” Its a good question. And it seems, at least according to the music video, there is no good answer.Actors in the video dress up like the animals theyre singing about. One of the brothers dresses up like a fox. There is a surprising and silly dance in the video that takes the viewer a bit offguard. The videos appeal is the songs simple rhythm and catchy chorus (副歌)The makers of the video never expected the video to do well or even to be taken seriously. In fact, it started out as a joke. The song was written by two brothers from Norway, Vegard and Bard Ylvis ker. The brothers have their own latenight talk show in Norway. They thought the video would be so bad that it would give them something to talk about on their show.On their website, they say the video was “supposed to entertain a few Norwegians for three minutes and thats all.” But people started loving it. Some people say that once you listen to the delightfully silly song, you want to listen to it again and again. The brothers have been guests on some major North American talk shows. They say theyre happy about the success of their video, but they know that tomorrow something else could come along and be even bigger. 语篇解读：本文介绍了最近网络上很流行的一首歌：The Fox。具体说明了这首歌的特点、创作缘由以及人们对这首歌的喜好程度。9What can be learnt about the music video invented by Psy?AIt featured the traditional style of Korean music.BIt was difficult for people to follow.CIt was named after a new virus.DIt could make people relax a lot.解析：选D细节理解题。根据文章第三段最后一句“The videos appeal is the songs simple rhythm and catchy chorus (副歌). ”这首歌的节奏很简单，副歌部分很吸引人。再根据倒数第二段最后一句“Some people say that once you listen to the delightfully silly song，you want to listen to it again and again.”可知有些人一听到这个令人高兴的音乐就会一遍一遍地再听。说明这首歌让人很放松，人们都想听它。可知，故D项正确。10Which of the following best describes the new music video The Fox?AIt can catch the viewers heart easily by its amusing tune and dance.BIt features the same story with the music video Gagnam Style.CIt answers the question“What does the fox say？”exactly.DIt has the real animals in the video.解析：选A推理判断题。根据文章倒数第二段最后一句“Some people say that once you listen to the delightfully silly song，you want to listen to it again and again.”可知有些人一听到这个令人高兴的音乐就会一遍一遍地再听。说明这首歌能够抓住听众的心。故A项正确。11It can be inferred from the passage that nowadays most people _.Alike to enjoy music with simple and easy style.Bhave difficulty in understanding the viral movie music.Care working hard for the advancement of classic music.Dare tired of many music videos which are popularized through Internet too quickly.解析：选A推理判断题。根据第三段最后一句“The videos appeal is the songs simple rhythm and catchy chorus(副歌)”可知这首歌的节奏很简单，说明人们很喜欢这种简单容易的风格的歌。故A项正确。12The underlined word “offguard” in Paragraph 3 is closest in meaning to _.AAnnoyed.BOffended.CUnexpected.
