Australian sea lions are endangered.Their numbers have dropped by over 60% in the last 40 years.Scientists wanted to learn more about how sea lions use different areas of the sea floor to gather food. But studying the sea floor is difficult.Underwater robots are expensive，they often move slowly，and they can’t go everywhere.So scientists at the University of Adelaide came up with a different plan—tying cameras to sea lions.The sea lions could cover large areas of the ocean floor quickly，and dive deeply to places humans can’t reach. The researchers used eight healthy females from two different groups of sea lions.They chose females because they would soon return to land to feed their young pups.That meant the scientists could easily get the cameras back.The scientists put the sea lions to sleep and temporarily attached a light-weight camera and GPS tracker to the animals.The team worked with animal experts to make sure the sea lions were treated well.Before long，the sea lions woke up and headed out to sea. Over the next few days，the eight sea lions traveled 348,560 kilometers underwater，diving as deep as 110 meters below the surface. In all，the animals collected 89 hours of video，letting the researchers see exactly what the animals saw.The results were exciting.The videos showed the sea lions hunting for food and proved that mother sea lions teach their pups how to hunt. The videos recorded the sea floor in places that had never been seen before.The researchers were able to identify six different types of sea floor environments，such as areas with lots of marine plants，or with bare sand.The videos gave the team a good idea of the kinds of plants and animals living in each of those environments. 1.What does the underlined word “endangered” in paragraph 2 probably mean? A.Rare and valuable. B.In need of training. C.Common and popular. D.In face of disappearing. √ 词义猜测题。根据画线词下文“Their numbers have dropped by over 60% in the last 40 years.”可知，在过去 40 年里，海狮的数量下降了60%以上。由此可知，海狮处于濒危状态。画线词与in face of disappearing“面临消失”意思相近。故选D项。 解析 2.Why were sea lions chosen for studying the sea floor? A.Because underwater robots are less developed. B.Because sea lions are easy to catch and release. C.Because sea lions can reach where humans can’t. D.Because sea lions have a strong sense of direction. √ 细节理解题。根据第三段中的“Underwater robots are expensive，they often move slowly，and they can’t go everywhere.”以及“The sea lions could cover large areas of the ocean floor quickly，and dive deeply to places humans can’t reach.”可知，选择海狮研究海底是因为海狮能代替昂贵的机器人到达人类无法到达的地方。故选C项。 解析 3.What is paragraph 4 mainly about? A.Scientists observed sea lions’ hunting behavior. B.Scientists prepared the sea lions for the journey. C.The sea lions were chosen based on their age and sex. D.Sea lions were carefully monitored during the research. √ 段落大意题。根据第四段中“The researchers used eight healthy females from two different groups of sea lions.”以及“The scientists put the sea lions to sleep and temporarily attached a light-weight camera and GPS tracker to the animals.”等内容可知，本段主要介绍了科学家选择出健康的海狮，然后让它们进入睡眠状态，并在它们身上安装设备，这些都是为海狮潜入海底之旅做的准备工作。故选B项。 解析 4.What is probably the best title for the passage? A.The Diet of Australian Sea Lions B.Underwater Journeys of Sea Lions C.Sea Lions Help to Map Ocean Floor D.The Importance of Protecting Sea Lions √ 标题归纳题。文章开篇提到“Australian scientists have come up with a clever way to study hard-to-reach areas of the sea floor: they tied cameras to sea lions.”，接着讲述海狮帮助科学家获取海底信息等内容，所以文章主要讲了海狮帮助绘制海底地图。C选项适合作本文标题。故选C项。 解析 Ⅵ.完形填空 Ohio grandparents Karen and Wayne Gamble had three grandchildren—Brooke，living out of town，Tori Hahlen and Luke，living out of the state.They were looking for a chance to spend time together while they were all home for Christmas Day since they lived 1 . 1.A.peacefully B.separately C.poorly D.hard 语篇解读　这是一篇记叙文。文章讲述Karen和Wayne Gamble的三个孙辈住在不同的地方，圣诞节时他们在祖父母家团聚过夜的暖心故事。 √ peacefully平静地；separately分别地；poorly贫穷地；hard努力地。由上文“Ohio grandparents Karen...out of the state.”可知，他们三个“分别”住在不同的地方。故选B项。 解析 To surprise their grandparents this holiday season，the three grandchildren knocked on their grandparents’ door with overnight bags，pillows，snacks and games—everything they needed for a nostalgic(怀旧的) party. “Are you 2 ？” said Hahlen’s shocked grandmother，adding，“That’s the best Christmas 3 ever！” 2.A.serious B.silly C.patient D.outgoing 3.A.list B.wish C.image D.present √ √ 2.serious严重的，认真的；silly傻的；patient耐心的；outgoing外向的。由下文“Hahlen’s shocked grandmother”可知，祖母对他们三个要留下过夜感觉很惊讶，所以问他们是不是“认真的”。故选A项。 3.list 清单；wish愿望；image印象；present礼物。上文提到孙辈们带着行李、零食等突然到访祖父母家，给祖父母带来惊喜，所以祖母说这是有史以来最好的圣诞“礼物”。故选D项。 解析 For dinner，the grandchildren 4 with plenty of pizza and buffalo chicken dip as soft piano played in the background of the clip.Luke said，“It’s just us tonight.It 5 so many childhood memories of sleepovers(过夜) at our grandparents’.” 4.A.looked around B.ran away C.showed up D.gave in 5.A.hides B.destroys C.orders D.recreates √ √ 4.look around环顾四周；run away逃跑；show up出现；give in屈服。由下文“with plenty of pizza and buffalo chicken dip”以及语境可知，这里指孩子们带了很多食物“出现”在祖父母家。故选C项。 5.hide隐藏；destroy破坏；order命令；recreate再创造，重现。由下文“many childhood memories of sleepovers(过夜) at our grandparents’”可知，这里指这次在祖父母家过夜“重现”了许多童年记忆。故选D项。 解析 After that，they all had their 6 of how their grandparents each would answer—Grandma would cry tears of 7 and Grandpa would chuckle and tease them for making Grandma 8 . 6.A.praise B.guess C.doubt D.idea 7.A.anxiety B.confidence C.joy D.pity 8.A.cry B.sweat C.laugh D.argue √ √ √ 6.praise表扬；guess猜测；doubt怀疑；idea主意。由下文“how their grandparents each would answer”可知，这里指孩子们“猜测”祖父母将会有什么样的反应。故选B项。 7.anxiety焦虑；confidence信心；joy喜悦；pity怜悯。由上文“That’s the best ever！”以及语境可知，这里指祖母将会由于“喜悦”而哭。故选C项。 8.cry哭；sweat流汗；laugh笑；argue争论。由上文“Grandma would cry”可知，这里指祖父将会取笑他们让祖母“哭”了。故选A项。 解析 The family filled their 9 with quality time and some of their favorite 10 ：They played games，drank hot chocolate and the girls even 11 their grandmother a set of festival pajamas(睡衣) to match their own. 9.A.weekday B.morning C.night D.daytime 10.A.classes B.talks C.visits D.activities 11.A.returned B.brought C.sold D.mailed √ √ √ 9.weekday工作日；morning早上；night晚上；daytime白天。由下文“their perfect night was ”可知，这里指孩子们通过他们最喜欢的活动充实他们的“夜晚”。故选C项。 10.class班级，课程；talk交谈；visit访问；activity活动。由下文“They played games，drank hot chocolate”可知，这里指他们最喜欢的“活动”。故选D项。 11.return返回，归还；bring带来；sell售卖；mail邮寄。由下文“a set of festival pajamas(睡衣) to match their own”以及语境可知，这里指女孩们甚至给祖母“带来”一套节日睡衣，与她们自己的那套相配。故选B项。 解析 After watching their favorite movie Home Alone，their perfect night was 12 . 12.A.complete B.lasting C.near D.natural √ complete完全的，结束的；lasting持久的；near接近的；natural自然的。由上文“After watching their favorite movie Home Alone”以及语境可知，这里指看了电影后，他们完美的夜晚就“结束”了。故选A项。 解析 Karen’s heart was 13 .“I have never had a nicer 14 in my whole life.I want to keep it 15 ，” she says.“They took every little detail into account and every single moment was perfect.” 13.A.treated B.warmed C.broken D.stolen 14.A.adventure B.dream C.surprise D.agreement 15.A.all the time B.in no time C.from time to time D.at a time √ √ √ 13.treat治疗；warm温暖；break打破；steal偷。由下文“They took every little detail into account and every single moment was perfect.”可知，这里指Karen的心被这一晚“温暖”了。故选B项。 14.adventure冒险；dream梦想；surprise惊喜；agreement协议。由上文“To surprise their grandparents this holiday season”以及语境可知，这里指Karen觉得自己这辈子从未有过如此“惊喜”。故选C项。 15.all the time一直；in no time很快；from time to time不时地；at a time每次。由下文“They took every little detail into account and every single moment was perfect.”可知，这里指这一晚很美好，所以Karen想“一直”保留这段记忆。故选A项。 解析 Ⅶ.语法填空 The Water-Splashing Festival(泼水节) is a traditional festival for the Dai people in Yunnan Province,1. marks the official New Year celebration for over one million Dai people living in China.2.
