The little animal’s mother was killed by a car. These girls took the baby sloth to Judy, the owner of a hotel. Judy wanted to help, but she didn’t know how to look after the sloth, so she called the zoo. With the help of the zoo, Judy took good care of the baby sloth. She named the baby sloth Buttercup. After her first success, more people brought Judy wounded (受伤的) sloths or baby sloths they found. Judy then opened a help centre. Today, the help centre has saved more than 500 sloths. Sloths mainly live in the forests of Central America. We can also see some in South America. They hang onto the trees with their claws (爪). There are two main types of sloths. You can know them by the number of their claws. Sloths hardly move. They spend most of their time sleeping in the trees. But now, with the increase (增长) of population, human beings (人类) cause a lot of problems for these slow and quiet animals. The main problem is that the forests are becoming smaller and smaller. When trees are cut down, sloths will fall and hurt themselves. Some sloths live near human beings and they sometimes are hit by cars or killed by dogs. 16．Why did Judy open a help centre? 17．Where do the sloths live? 18．Can the sloths run very fast? 19．What is the main problem for sloths? 20．What can we learn from the passage? 四、短文填空 阅读下面短文，在空白处填入一个适当的单词 (有提示词的，填入所给单词的正确形式)。 There are many different kinds of animals.

If more people start to care about animals, animals will live 30 happy life. 1 学科网（北京）股份有限公司 $$ Unit 1 Section A（ 2a-2f） (分层练习） 一、单项选择 1．—________do they kill elephants? —Because they kill them ________their ivory. A．What; on B．What; for C．Why; for D．Why; on 【答案】C 【详解】句意：——他们为什么杀大象？——因为他们为了象牙杀了它们。 考查特殊疑问句、介词辨析。What什么，问事或物；why为什么，问原因；on在……上面；for为、给……，表动作的对象、原因；根据答语“Because they kill them…”判断空格1是为什么，疑问词用why；从文字的表层意思可知空格2指为了象牙杀了它们，故选C。 2．—________ does the girl ________? —Australia. A．Where; be from B．Why; come from C．Where; come from D．When; be from 【答案】C 【详解】句意：——这个女孩来自哪里？——澳大利亚。 考查特殊疑问句及动词短语。where哪里，询问地点；why为什么，询问原因；when什么时候，询问时间； be/come from来自……，固定短语。根据答语“Australia.”可知，此处是询问地点的，应使用where提问；由句中的助动词“does”可知，谓语动词应为行为动词，因此此处使用come from，表示“来自”。故选C。 3．I’m sorry to keep Mr. Li ________ for me for 20 minutes, so I will say sorry to him. A．waited B．to wait C．waiting D．wait 【答案】C 【详解】句意：我很抱歉让李先生等我20分钟，所以我会对他说对不起。 考查非谓语动词。keep sb. doing sth. 意为“使某人一直做某事”，所以空处应选waiting。故选C。 4．They are my ________ friends. We always go to school together (一起). A．boring B．dangerous C．close D．cold 【答案】C 【详解】句意：他们是我的亲密的朋友。我们总是一起上学。 考查形容词辨析。boring无聊的；dangerous危险的；close亲密的；cold冷漠的。根据“They are my...friends. We always go to school together”可知，句中表述他们总是一起上学，由此可以推测他们之间的关系很“亲密”。此处使用“close”意为“亲密的”，“my close friends”意为“我亲密的朋友”与总是一起上学所体现的友好关系相符。故选C。 5．Eric, ________ eat in the classroom. It’s a school rule. A．don’t B．not C．doesn’t D．no 【答案】A 【详解】句意：艾瑞克，不能在教室里吃东西。这是学校的规定。 考查否定祈使句。根据“Eric, ...eat in the classroom.”可知，此处是对艾瑞克提出的命令，禁止在教室里吃东西，该句为否定祈使句，其构成为don’t+动词原形。故选A。 二、单词拼写 6．My brother runs very f , and he wants to be a good runner. 【答案】(f)ast 【详解】句意：我哥哥跑得很快，他想成为一名优秀的跑步者。根据“he wants to be a good runner”可知，他想成为优秀的跑步者，所以应是跑得很快，fast“快速地”，副词修饰动词runs。故填(f)ast。 7．L at the dog. It is very lovely. 【答案】(L)ook 【详解】句意：看这条狗。它很可爱。根据“… at the dog. It is very lovely.”和首字母提示可知，此处应是要求观察或看看这只狗，look at“看”，动词，符合题意，且祈使句应用动词原形开头，句首首字母大写。故填(L)ook。 8．The bird has wings and it can f . 【答案】(f)ly 【详解】句意：鸟儿有翅膀，它能飞翔。根据句意及单词首字母f可知，结合常识，can后接动词原形fly，意为“飞” 。故填(f)ly。 9．—Please g me the book on the desk. —OK. Here you are. 【答案】(g)ive 【详解】句意：——请把桌子上的书给我。——好的，给你。根据“g... me the book on the desk”可知，是指把桌子上的书给我，give“给”，句子是祈使句，动词用原形。故填(g)ive。 10．My good friend Lisa is very s and she can work out all the math problems easily. 【答案】(s)mart 【详解】句意：我的好朋友丽莎非常聪明，她可以很容易地解决所有的数学问题。根据“she can work out all the math problems easily.”及首字母可知，丽莎很聪明，用形容词smart“聪明的”，作表语。故填(s)mart。 11．I jumped into the pool and stayed in the c water for an hour. 【答案】(c)ool/(c)old 【详解】句意：我跳进池子里，在凉水里呆了一个小时。根据“I jumped into the pool”和首字母可知，池子里的水是凉爽的/冷的；cool“凉爽的”或cold“冷的”，形容词作定语，修饰名词water。故填(c)ool/(c)old。 12．My mum made some delicious (sandwich) for the picnic. 【答案】sandwiches 【详解】句意：我妈妈为野餐做了一些美味的三明治。根据句子结构，空格处应填名词作宾语，空格前为“some”，故此处应用名词sandwich的复数形式，故填sandwiches。 13．I help my mother (do) the homework on Sundays. 【答案】to do/do 【详解】句意：星期天我帮妈妈做家务。根据题干空前的“help my mother”可知，帮助某人做某事应为“help sb to do sth”或“help sb do sth”。再根据所给提示词可知，do the housework表示“做家务”。故填to do/do。 14．The students are going to the museum to learn about some （amaze）things. 【答案】amazing 【详解】句意：学生们要去博物馆了解一些令人惊奇的东西。名词things（东西）需用形容词修饰，amaze的形容词是amazed和amazing，amazed修饰人，表示“人感到惊奇”，amazing修饰物，表示“事物令人感到惊奇”，句中things表示“物”，所以使用amazing进行修饰。故填amazing。 15．He is (interest) in science at school. He says he wants to be a scientist in the future. 【答案】interested 【详解】句意：他在学校时对科学感兴趣。他说他将来想成为一名科学家。根据“He says he wants to be a scientist in the future.”可知，未来想成为一名科学家，说明他对科学感兴趣；interested“感兴趣的”，符合题意；be interested in“对……感兴趣”。故填interested。 三、完成句子 16．企鹅是我最喜欢的动物。 The penguin is my . 【答案】favorite/favourite animal 【详解】根据汉语提示，空缺处应填“最喜欢的动物”。favorite/favourite意为“最喜欢的”，形容词，作定语，修饰后面的名词；animal意为“动物”，可数名词，在句中作表语；空前有is，因此animal应为单数。故填favorite/favourite; animal。 17．多锻炼对你的健康有益。 Taking more exercise your health. 【答案】is good for 【详解】空处表示“对……有益”，用形容词短语be good for表示，主语是动名词短语，be动词用is。故填is；good；for。 18．孩子们上下跳跃来保持身体暖和。 The children jumped up and down to . 【答案】keep warm 【详解】保持暖和：keep warm，动词短语，与空前to构成不定式。故填keep；warm。 19．我喜欢它们走路的方式。 I like . 【答案】how they walk 【详解】根据中英文对照可知，缺少“它们走路的方式”的意思，how“……的方式”，they“它们”，walk“走路”，故填how；they；walk。 20．那里很冷，所以它们经常挤在一起。 It’s very cold over there, they often . 【答案】so stand close together 【详解】分析句子结构可知，前后句是因果关系，前因后果，所以空一填连词so；挤在一起：stand close together，句子时态为一般现在时，主语是they，谓语动词用原形。故填so；stand；close；together。 一、完形填空 阅读下面短文，掌握其大意，然后从各题所给的A、B、C、D四个选项中选出最佳选项。 Penguins look funny with their big bodies, short necks and short legs.

The little animal’s mother was killed by a car. These girls took the baby sloth to Judy, the owner of a hotel. Judy wanted to help, but she didn’t know how to look after the sloth, so she called the zoo. With the help of the zoo, Judy took good care of the baby sloth. She named the baby sloth Buttercup. After her first success, more people brought Judy wounded (受伤的) sloths or baby sloths they found. Judy then opened a help centre. Today, the help centre has saved more than 500 sloths. Sloths mainly live in the forests of Central America. We can also see some in South America. They hang onto the trees with their claws (爪). There are two main types of sloths. You can know them by the number of their claws. Sloths hardly move. They spend most of their time sleeping in the trees. But now, with the increase (增长) of population, human beings (人类) cause a lot of problems for these slow and quiet animals. The main problem is that the forests are becoming smaller and smaller. When trees are cut down, sloths will fall and hurt themselves. Some sloths live near human beings and they sometimes are hit by cars or killed by dogs. 16．Why did Judy open a help centre? 17．Where do the sloths live? 18．Can the sloths run very fast? 19．What is the main problem for sloths? 20．What can we learn from the passage? 【答案】16．Because she wants to save sloths. 17．Sloths live in the forests of Central America and South America. 18．No, they can’t. 19．The main problem is that the forests are becoming smaller and smaller. 20．We should stop cutting down trees and protect wild animals. 【导语】本文是一篇记叙文。文章主要讲述了朱迪建立救助中心，救助树懒的经历。 16．根据第二段“more people brought Judy wounded sloths or baby sloths they found. Judy then opened a help centre. Today, the help centre has saved more than 500 sloths.”可知，朱迪创办了一个救助中心，救助了超过500只树懒；据此可知朱迪开一个救助中心是为了救助树懒。故填Because she wants to save sloths. 17．根据第三段“Sloths mainly live in the forests of Central America. We can also see some in South America.”可知，树懒住在中美和南美的森林里。故填Sloths live in the forests of Central America and South America. 18．根据第三段“ Sloths hardly move”及最最后一段“ these slow and quiet animals”可知，树懒几乎不移动，树懒很缓慢很安静；据此可以推测，树懒不能跑得很快，应用否定回答“no, 主语+助动词/情态动词/助动词+not”，指代复数名词“Sloths”应用they，故填No, they can’t. 19．根据最后一段“The main problem is that the forests are becoming smaller and smaller.”可知，树懒面临的主要问题是森林正在变得越来越小。故填The main problem is that the forests are becoming smaller and smaller. 20．开放性试题，言之有理即可。参考答案为：We should stop cutting down trees and protect wild animals. 四、短文填空 阅读下面短文，在空白处填入一个适当的单词 (有提示词的，填入所给单词的正确形式)。 There are many different kinds of animals. Animals are 21 (we) friends. Some animals live in the big forest. And some animals are 22 (live) with people. Animals are very 23 (use) to people. Dogs can look 24 people’s houses. They can also 25 (help) people in need. Children like animals very much. They 26 (usual) go to the zoo with their parents on weekends. The zoo is a good place for 27 (child) to know about animals. Many animals 28 (be) in danger now because some people kill (杀死) 29 (they) for money. If more people start to care about animals, animals will live 30 happy life. 【答案】 21．our 22．living 23．useful 24．after 25．help 26．usually 27．children 28．are 29．them 30．a 【导语】本文介绍了动物是人类的朋友，并号召人类保护动物。 21．句意：动物是我们的朋友。修饰名词friends，应该填形容词性物主代词our“我们的”，故填our。 22．句意：并且一些动物和人类住在一起。根据“And some animals are…with people.”可知，设空处前是are，因此填现在分词living构成现在进行时，故填living。 23．句意：动物对人们来说非常有用。根据“Animals are very”可知，此处是说动物对人类来说很有用，useful“有用的”，作表语。故填useful。 24．句意：狗能看家。此句表示“看家”用固定短语look after，所以填after。 25．句意：它们也能帮助有需要的人。can是情态动词，后接动词原形，所以此处填动词原形help“帮助”，故填help。 26．句意：他们通常在周末和父母去动物园。修饰动词go用副词，usually“通常”，是副词。故填usually。 27．句意：动物园是孩子们了解动物的好地方。child的复数形式是children“孩子们”，此处泛指类别，填复数形式。故填children。 28．句意：许多动物现在处于危险之中，因为一些人为了钱而杀死它们。此句是陈述句，时态是一般现在时，主语Many animals是复数，所以be动词用are，故填are。 29．句意：许多动物现在处于危险之中，因为一些人为了钱而杀死它们。kill是动词，后接人称代词宾格作宾语，they的宾格是them“它们”，故填them。 30．句意：如果更多的人开始关心动物，动物们将会过上幸福的生活。根据“happy life.”可知，此处泛指一种生活，happy是辅音音素开头的单词，所以不定冠词用a，故填a。 1 学科网（北京）股份有限公司 $$
