The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoths and mastodon to modern elephants—the Asian elephant, African forest elephant, and African savanna elephant. Once they obtained DNA sequences( 序 列 )from two fossils( 化 石 ) , mammoths and mastodons,the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths. The scientists used detailed genetic analysis to prove that the African savanna elephant and the African forest elephant have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists. There has long been debate in the scientific community that the two might be separate species, but this is the most convincing scientific evidence so far that they are indeed different species. Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species, despite the elephants' significant size

differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA. Alfred Roca, assistant professor in the Department of Animal Sciences at the University of Illinois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purposes. Since 1950, all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinctive animals, the forest elephant should become a bigger priority (优先)for conservation purposes.” 16.One of the fossils studied by the researchers is that of ________. A.the Asian elephant B.the forest elephant C.the savanna elephant D.the mastodon elephant 17.The underlined word “divergence” in Paragraph 4 means “________”. A.evolution B.exhibition C.separation D.examination 18.The researchers' conclusion was based on a study of the African elephant's ________. A.DNA B.height C.weight D.population 19.What are Alfred Roca's words mainly about? A.The conservation of African elephants. B.The purpose of studying African elephants. C.The way to divide African elephants into two units. D.The reason for the distinction of African elephants. 20.Which of the following can be the best title for the passage? A.Naturalists' Beliefs about Elephants B.Amazing Experiments about Elephants C.An Unexpected Finding about Elephants D.A Long Scientific Debate about Elephants Ⅲ.阅读表达 阅读下面短文并回答问题,然后将答案写到相应的横线上(请注意问题后的词数要求)。 [1] Do you want to work with people or animals or machines or tools? Do you want to work indoors or outdoors, directly serve people in need or serve people behind the scenes? These are the typical questions that a volunteer service agency would ask. [2] Every year, thousands and thousands of people in the west offer volunteer services. Volunteering greatly strengthens the community partly because it helps the old, the young, the weak, the sick, the disabled and the injured to overcome difficulties. [3] Volunteers usually help in many different ways. They may give people advice, offer friendship to the young, drive the elderly to church, counsel kids against drugs. Work as an assistant in a school or nursing home, raise funds, plant trees, help out in local libraries and do many other things.

[4] Volunteering can be a few hours a week or a few hours a month, time during the day, evenings or weekends, either part time or full time. Anybody ____________ can become a volunteer. [5] The art of volunteering is a process of both giving and receiving. Volunteering allows volunteers to meet new people and make new friends and mix with people from all walks of life. Volunteering is an excellent way to experiment, practice and try out new techniques and skills. It is much more effective to practice a skill than to read about it or study it in a classroom. Volunteering is a great way to develop good teamwork skills, discover your individual talents and explore career choices. Being a volunteer takes individuals on a wonderful journey and helps them learn many important things beyond their school learning. 21.What is the best title of the passage? (no more than 10 words) ________________________________________________________________________ 22.What advantages can volunteer service bring volunteers besides making new friends? (no more than 9 words) ________________________________________________________________________ 23.Please fill in the blank in the fourth paragraph with proper words, phrases or sentence to complete the sentence. (no more than 10 words) ________________________________________________________________________ 24.What kind of volunteer jobs would you like to take? Why? (no more than 30 words) ________________________________________________________________________ 25.What does the word “it” (Line 3, Paragraph 2) probably refer to? (no more than 4 words) ________________________________________________________________________

课时作业(九) Ⅰ.1.C 考查宾语从句。句意:当你拿回你的试卷后,要特别注意批改过的内容。pay special attention to 中的 to 是介词, 后面的句子作 to 的宾语, 在宾语从句中缺主语, 故选 what。 2. 考查固定句型和代词。 D dislike, like, hate, appreciate 等表示“爱, 恨”等情感动词, 不直接接从句,而是借助形式宾语 it,后面接的是 when 引导的从句。故选 D。 3.A 考查时态。第一个句子用的是现在完成时,回答的是还没有拿到试卷,从下文 的 at this moment 看出试卷还在被批阅中。故用现在进行时的被动语态。 4.B 考查介词短语辨析。(be)in danger“(处于)危险中”。句意为:总统生命垂危的 消息使国家的经济危机每况愈下。 5.D 考查倒装和语态。in which = where,表示处所,置于句首,引起一个完全倒 装句。the names and addresses of his friends 和 write 是动宾关系,所以用被动语态。 6.C 考查介词短语辨析。句意:这架坠毁飞机的幸存者没有食物和水,面对极端寒 冷的天气束手无策。in the possession of “被??拥有”;in the charge of “由??负责”; at the mercy of “受/听任??摆布”;at the risk of “冒??的危险”。从句意判断选 C。 7.B 考查非谓语动词。the postman 与 bite 之间是被动和完成的关系,所以用过去分 词形式,此处过去分词作状语,表原因。 8.A 考查疑问词辨析。谈到距离,我们自然会想到 how far,因此很容易误选 B。其 实,在英语中 distance 不能与 how far 连用,只能用 what。同样,问人口多少,不能说 How many is the population of China?应说 What's the population of China? 9.C 考查动词时态和语态。attention 和 fix on 之间是被动关系,故排除 A、B 两项, 再根据 Now 可知,应用现在进行时的被动语态。 10.C 考查时态和语态。此处用进行时的被动语态表示说话时正在进行的动作,衣服 被洗,故用现在进行时的被动语态。 11. 句意为: C 在政府的帮助下, 那些受地震影响的人们已经搬到了新的居住地。 affect 是及物动词,意为“影响”,此处为过去分词短语作后置定语,相当于 who are affected?。 12.A 考查动词辨析。be applied to+n.意为“被应用于??”,符合题意,故答案为 A。 13.B 考查代词 it 在 appreciate 后的用法。表示喜欢、恨、感激等心理活动的动词, 如 like, love, hate, appreciate 等后加上 it 作形式宾语,再加 if/wh-从句作真正的宾语。 14. 考查动词的时态。 A 联系空后 “so we must take measures to protect them”我们知道, 很多野生动物将要灭绝。所以用进行时表示将来。 15.A 考查倒装结构。本题为一个含有比较状语从句的复合句,第三个 as 引导的是 比较状语从句,其完整结构为“as all other animals on the earth are endangered”,endangered 承 前省略了,由于主语“all other animals on the earth”比较长,故采用了倒装结构,将谓语动词 are 提前,以避免头重脚轻。 Ⅱ.本文为科普说明文。主要介绍关于大象的最新研究成果:非洲大象被分成两种完全 不同的品种——非洲草原大象和非洲森林大象。 16.D 细节理解题。根据第三段 Once they obtained DNA sequences(序列)from two fossils(化石),mammoths and mastodons, the team compared them with DNA from modern elephants.可判断选 D 项。 17.C 词义猜测题。根据第四段 The scientists used detailed genetic analysis to prove that the African savanna elephant and the African forest elephant have been distinct species for several million years 可知,科学家已证实,非洲的草原大象与非洲的森林大象几百万年来都不属于 同一品种,即可推断两种大象的分离应发生在??由此可推断画线词应意为 separation,故

选 C 项。 18.A 细节理解题。根据第三段 Once they obtained DNA sequences(序列)from two fossils(化石),mammoths and mastodons, the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths 可判断研究者的结论是建立在对非洲大象的 DNA 的研究结果的基础上的,故选 A 项。 19. 推理判断题。 A 根据最后一段 Now that we know the forest and savanna elephants are two very distinctive animals, the forest elephant should become a bigger priority (优先)for conservation purpose.可推断他的讲话是围绕对非洲大象的保护而陈述的,故选 A。 20. 主旨大意题。 C 根据主题段第一段可知, 本文主要介绍关于大象的最新研究成果: 非洲草原大象和非洲森林大象实际为两种完全不同的物种。由此判断选 C。 Ⅲ.本文为主要介绍了西方的志愿者服务的有关事项及益处。 21.Volunteer Service in the West 主 旨 大 意 题 。 纵 观 全 文 以 及 由 主 题 句 即 第 二 段 第 一 句 “Every year, thousands and thousands of people in the west offer volunteer services.”可知本文主要介绍了西方的志愿者服 务。 22.Meeting new people and mix with different people. 从第五段第二句“Volunteering allows volunteers to meet new people and make new friends and mix with people from all walks life.”得知志愿工作能让志愿者遇见不同的人, 交上新朋友, 并同各种背景的人打交道。 23.who is willing / likes to serve people in need 句子填空题。此处是对 volunteer 的解释,由第一段中的第二句“serve people in need”可 知志愿者应该是愿意帮助有需要的人。 24.I like to help out in local libraries, because I like books very much. I'll arrange them in good order so that readers can easily find what they want. 归纳表达题。此处可以根据自己的爱好与能力选择自己愿做的志愿者工作。 25.Volunteering 代词指代题。由画线词所在句“Volunteering greatly strengthens the community partly because it helps the old ?”可知此处 it 应该指的是“volunteering”。
