class.I fell in love and stuck with it for the next seven years.During that time my father also became more involved in the Irish music world,so he would play,and I would dance.My ethnic heritage (族裔归属) is German and Irish,but because I was surrounded by traditional Irish music and dance in my home,I have grown to be more interested in and connected to my Irish heritage.‎ When I started interning (实习) for the Folklife Festival,I became interested in traditional Basque music and dance and I learned that their experience with dance is very similar to my own.‎ There are so far over 170 Basque organizations in 24 countries,with a greater population of Basques outside of the Basque country than in it.The separation they experience from their homeland is both physical and psychological,so being part of a group with the same interests is an important social support system.These organizations contribute to the continuation of Basque culture,language,and community,and encourage future generations to learn about their ethnic heritage.One of the ways through which they achieve this is dance.‎ While learning and performing Basque dances,they connect to their heritage,experience a part of their homeland,preserve Basque culture,and create connections and friendships that last a lifetime.‎ Californian Valerie Arrechea began teaching alongside her father at the age of thirteen and on her own at sixteen.For her,dance is her preferred expression of heritage;it provides a way to be proud of her Basque heritage.‎ The dance performances of North American Basque organizations have developed the interest of non-Basque Americans as well.Janet Iribarne from the Basque Dancers explained that their organization is open to anyone,and after seeing her group perform,several of her non-Basque friends have developed their own love of Basque traditions as well.‎ ‎【篇章导读】本文是记叙文。作者在一次实习中接触到了巴斯克传统音乐和舞蹈并了解到:它们不仅带给巴斯克裔美国人民族认同感,由此建立的友谊也使他们终生难忘。‎ ‎1.What is the reason for the author’s preference for Irish dance?‎ ‎　　　　　　　　　　　　　　　　‎ A.Her dance teacher.‎ B.Her love of Irish music.‎ C.Her interning experience.‎ D.Her family’s strong root in dance.‎ 答案D 解析细节理解题。根据第一段中的“because I was surrounded by...to my Irish heritage”可知,作者喜欢爱尔兰舞蹈是源于家庭氛围的熏陶。‎ ‎2.What do we know about Basque people?‎ A.Most of them live abroad.‎ B.Their culture is being lost.‎ C.They live in poor conditions.‎ D.Their population is increasing.‎ 答案A 解析细节理解题。根据第三段中的“with a greater population of Basques outside of the Basque country than in it”可知,大多数巴斯克人生活在国外。‎ ‎3.What is the purpose of Basque organizations?‎ A.To help Basques in need.‎ B.To preserve Basque culture.‎ C.To provide medical treatment for Basques.‎ D.To support overseas Basque children for education.‎ 答案B 解析细节理解题。根据第三段中的“These organizations contribute to the continuation of Basque culture,language,and community,and encourage future generations to learn about their ethnic heritage.”可知,这些巴斯克组织旨在保护、传承传统文化。‎ B Climate change,not human hunting,may have wiped out the thylacine (袋狼),according to a new study based on DNA from thylacine bones.‎ The meat-eating marsupials (有袋动物) died out on mainland Australia a few thousand years ago,but survived in Tasmania,an island of southeast Australia separated from the mainland,until the 1930s.Until now,scientists had believed the cause of this mainland extinction was increased activity from native Australians and dingoes (Australian wild dogs).‎ Scientists behind the University of Adelaide study,which was published in the Journal of Biogeography on Thursday,collected 51 new thylacine DNA samples from fossil bones and museum skins — the largest data set of thylacine DNA to date.The paper concluded that climate change starting about 4,000 years ago — in particular drier seasons caused by the weather systems known as El Nino-Southern Oscillation — was likely the main cause of the mainland extinction.‎ The ancient DNA showed that the mainland extinction of thylacines was rapid,and not the result of loss of genetic diversity.There was also evidence of a population crash in thylacines in Tasmania at the same period of time,reducing their numbers and genetic diversity.‎ Associate Professor Jeremy Austin,deputy director of the University’s Australian Centre for Ancient DNA,said Tasmania would have been protected from mainland Australia’s warmer,drier climate due to its higher rainfall.He argued that climate change was “the only thing that could have caused,or at least started,an extinction on the mainland and caused a population crash in Tasmania.”‎ ‎“They both occurred at about the same time,and the other two things that have been talked about in the past that may have driven thylacines to extinction on the mainland were dingoes and humans.So the only explanation that’s left is climate change.And because that population crash happened at the same time that the species went extinct on the mainland,our argument is there’s a common theme there and the only common theme that’s there is this change in climate.”‎ ‎【篇章导读】本文是说明文。最新研究发现,澳洲袋狼的灭绝源于气候变化,而非土著人和野狗的威胁。‎ ‎4.What happened to thylacines in the 1930s?‎ A.They died out on mainland Australia.‎ B.They were hunted in large numbers.‎ C.They survived in Tasmania.‎ D.They were no longer seen.‎ 答案D 解析细节理解题。由第二段中的“The meat-eating marsupials...until the 1930s.”可知,到二十世纪三十年代,袋狼彻底绝种了。‎ ‎5.What did scientists believe before the University of Adelaide study?‎ A.Marsupials were all meat-eating animals.‎ B.Dingoes should be removed from Australia.‎ C.Thylacines had no enemies on mainland Australia.‎ D.Native people were responsible for the extinction of thylacines.‎ 答案D 解析细节理解题。由第二段中的“Until now,scientists had believed...native Australians and dingoes (Australian wild dogs)”可知,在这项研究发布之前,科学家们一直认为是土著人和澳大利亚野狗造成了袋狼的灭绝。‎ ‎6.What’s the difference between mainland Australia and Tasmania?‎ A.Tasmania has more dingoes.‎ B.Tasmania has more wet days.‎ C.Tasmania has a higher temperature.‎ D.Tasmania has more native Australians.‎ 答案B 解析推理判断题。由第五段中的“Tasmania would have been protected from mainland Australia’s warmer,drier climate due to its higher rainfall.”可知,塔斯马尼亚降雨量大,气候潮湿。‎ ‎7.What’s the best title for the text?‎ A.DNA is playing an important role B.Climate change led to thylacines’ disappearance C.Australian animals are facing a population crash D.Native Australians and dingoes were misunderstood 答案B 解析标题归纳题。文章首段即点明中心——袋狼的灭绝是由气候变化造成的,文末又对这一观点进行了呼应。B项做标题最能概括文意。‎ 二、七选五 Deciding whether or not to take part in an extracurricular (课外的) activity can be a challenge.Before signing up to play on the volleyball team,first consider the advantages and disadvantages of such a decision.‎ ‎　1　 Students are successful when they take part in many activities.They do well in their classes and feel more connected to school.Research shows that students in extracurricular activities have better attendance and grades. ‎ Extracurricular activities also help students make new friends and lasting relationships.　2　Even though we became friends a long time ago,we are still close today. ‎ While these activities have many advantages,students should consider the downside as well.　3　 Extracurricular activities can be too much for students who do not practice good time management.Students need to be good at managing their time between different activities. ‎ Another downside to extracurricular activities involves transportation.　4　 This situation limits students’ extracurricular choices to those outside the school and closer to home.A few of my classmates joined the school’s cultural club.They later discovered that it met after school.These students dropped out of the club because they had to catch their buses. ‎ Only you can decide if extracurricular activities are right for you.Activities outside the school can help you succeed in many areas of your life.　5　 Are you up for a challenge? ‎ A.We were both in the eight-and-under age group.‎ B.Some clubs or sports meet before or after school.‎ C.One downside is that it can create a busy life for students.‎ D.Many students are tired from all the things they have to do.‎ E.Taking part in extracurricular activities has many advantages.‎ F.I met my best friend when we were on the YMCA swim team.‎ G.However,you need good time management skills to deal with a busy life.‎ 答案与解析 ‎【篇章导读】本文是议论文。要不要参加课外活动对于许多学生来说是个需要权衡利弊的问题。‎ ‎1.E　本空为本段的主题句,本段主要阐述了参加课外活动的学生们在学习方面表现更突出,即参加课外活动的好处。‎ ‎2.F　本空是对前一句的举例说明,且下一句中的we became friends与F项中的I met my best friend在语意上相关。‎ ‎3.C　由本空前一句可知,本段开始阐述参加课外活动的弊端;而本空后面的内容是对本空的进一步解释说明,阐述的是其中一个弊端,即让学生们更繁忙。‎ ‎4.B　B项内容与下一句形成因果关系,本空后面的This situation指代B项内容。‎ ‎5.G　本空前一句与G项内容形成转折关系,即课外活动虽有好处,但学生们需要恰当巧妙地安排时间,以应对繁忙的生活。‎ 三、语法填空 The jaguar (美洲豹) is the largest cat in the Americas.A hundred years ago,jaguars 1.　　　　　 (find) everywhere from the southwestern United States to Argentina,in South America.Today,jaguars are an endangered species throughout their 2. (nature) habitat and have been lost from 50 percent of ‎ their territory.Today they live 3.　　　　　 (most) in the Amazon rainforest.And jaguars aren’t the only animals losing their homes — according 4.　　　　　 the International Union for Conservation of Nature,habitat loss 5.　　　　　 (be) the main threat to about 85 percent of all endangered plant and animal species. ‎ Tropical rainforests cover only about 7 percent of Earth’s land,but they’re home to about half of all known plant and animal species.Most 6.　　　　　 (scientist) agree that about 80,000 acres (an acre is equal to 4,047 square metres) disappear every day when trees are cut down and land is cleared for farms.Trees also play 7.　　　　　 important role in climate change.Fewer forests mean that more greenhouse gases remain 8.　　　　　 (trap) in the atmosphere,the mixture of gases that surrounds the Earth. ‎ Grasslands,underwater habitats,and wetlands are also at risk.For example,the World Wildlife Fund reports that about half of the world’s wetlands 9.　　　　　 (disappear) since a hundred years ago as a result of being drained (排水) for either farmland 10. other industries.That means less space for animals to feed and raise their young. ‎ 答案与解析 ‎1.were found　考查一般过去时的被动语态。设空处所在句意为“一百多年前,从美国的西南部到阿根廷都能发现美洲豹的踪影”,故find与jaguars之间是被动关系,应用被动语态,且由A hundred years ago可知,此处应用一般过去时,故填were found。‎ ‎2.natural　考查形容词做定语的用法。设空处做定语修饰habitat,表示“自然的”,故填形容词natural。‎ ‎3.mostly　考查副词。设空处做状语修饰谓语动词live,表示“主要地”,故填副词mostly。‎ ‎4.to　考查介词。according to 意为“按照,根据……所说”。‎ ‎5.is　考查主谓一致。设空处所在句描述现在的情况,应用一般现在时,因为主语是habitat loss,故填is。‎ ‎6.scientists　考查名词复数。设空处做主语,表示“科学家”,因为scientist是可数名词,由Most及谓语动词agree可知,此处应填scientists。‎ ‎7.an　考查不定冠词。设空处所在句意为“树木在影响气候变化方面起着重要作用”,故填an。play an important role in...“在……方面起重要作用”。‎ ‎8.trapped　考查过去分词做表语的用法。设空处所在句意为“森林面积的减少意味着越来越多的温室气体停留在大气层里”,trap与greenhouse gases之间是被动关系,故填过去分词trapped。‎ ‎9.have disappeared　考查现在完成时。由since a hundred years ago可知,此处应用现在完成时,因为主语是half of the world’s wetlands,故填have disappeared。‎ ‎10.or　考查连词。either...or...“或者……或者……”。‎
