He is so positive (积极乐观) that I have never heard 2 single (单一的) word from him which is related to hopelessness! Unlike most moms and dads, my dad never says things that 3 make me feel sad. He is always there to give 4 encouragement and help. When I do something wrong, he always tells me 5 I should do next time in a positive way. For example, if I am 6 trouble, he often tells me to open the books he has bought for me. Then he asks me 7 the stories that can help me with the problems I’m facing. After that, we will have a discussion together. If it’s useless, he 8 me calm (镇静) down first and think about what happened to me by myself. 9 I’m not always a good kid because of my naughty (淘气) character, my dad never shouts at or gets angry with me. I know that he’s waiting for the day when I grow up and understand some important things in my life. I can see the reason why he is so positive is that he believes in himself, and also I 10 by him. He believes that whatever happens, it is under control. So we have nothing to worry about. Be positive! Sunshine will be in your life forever! 1．A．Optimistic B．More optimistic C．The most optimistic 2．A．the B．/ C．a 3．A．may B．may not C．must 4．A．mine B．me C．I 5．A．which B．what C．why 6．A．in B．of C．at 7．A．reading B．read C．to read 8．A．let B．is letting C．will let 9．A．Although B．Unless C．If 10．A．trust B．am trusted C．trusted 二、短文填空 阅读下面材料，在空白处填入1个恰当的词或括号内单词的正确形式，并将答案写在答题卡的相应位置。 I’m the eldest child in my family, so I need to set a good example 1 my two little cousins. I learned from my mother. She is my role model. Mum was also 2 (old) child in her family. She has two younger brothers. Mum was always calm, fair, and wise beyond her years. Even when Mum was only six years old, she used to 3 (share) with her brothers. If there was one piece of cake, mum would cut it into three pieces and let her brothers choose their pieces 4 (one). I do the same with my cousins. Mum says that if I do the right things, my cousins 5 (do) the right things, too. I work hard at school, and I try to be 6 (help) and kind all the time. As soon as I finish my homework, I always ask Grandma 7 I can help her with anything. Sometimes she wants me to help with the housework, but usually she just asks me to help my cousins with their homework. Sometimes, there’s a lot of 8 (stressed) in being a good role model. However, it makes me stronger. I guess I’m lucky to have Mum as 9 example. I hope that I can do as 10 (good) as Mum, and that when my cousins grow up, they respect me as much as Mum’s brothers respect her. 1 / 12 学科网（北京）股份有限公司 $ Unit 1 Teenagers today 核心语法精练 （条件状语从句和原因状语从句） 目录 二、考点夯基 1 二、单项选择 2 三、完成句子 9 四、句型转换 10 一、语法选择 11 二、短文填空 13 条件状语从句 条件状语从句的引导词主要有as long as(只要), if（如果）, unless（除非）。 在条件状语从句中，从句常用一般现在时表将来，即主将从现。 注意：宾语从句的引导词if表“是否” You will fail the exam if you don’t work hard. =You will fail the exam unless you work hard. 如果不努力学习，你考试会不及格的。 I don’t know if she will come tomorrow. 我不知道她明天是否会来。 原因状语从句 原因状语从句的引导词有because，since，as等。 注意：1. because和so不能同时使用。 2. since引导原因状语从句表示显然的或已为人知的理由，表示“因为，既然” He didn’t come to school yesterday because he was ill. 他昨天没来上学，因为他生病了。 Since everyone is here, let’s start.既然大家都到期了，我们就开始吧。 一、单项选择 1．If it ________ tomorrow, we’ll go hiking in the mountains.

A．if B．because C．but D．unless 【答案】B 【详解】句意：汤姆每天练习说英语，因为他想要提高它。 if如果；because因为；but但是；unless除非。根据语境可知，后半句“他想要提高它”是前半句“每天练习说英语”的原因，前后句构成因果关系。 二、完成句子 31．如果我们学好英语，就能更好地向外国游客介绍广交会。 We ________ ________ the Canton Fair to foreign visitors better ________ we ________ English well. 【答案】 can introduce if learn 【详解】原句中“能”、“介绍”、“如果”和“学”是关键词。①填情态动词can（能够，后接动词原形）；固定搭配introduce sth. to sb. 表示“向某人介绍某物”，因此②填introduce；③填连词if（引导条件状语从句，意为 “如果”）；if引导的条件状语中，主语谓语动词含有情态动词can，因此if从句要用一般现在时，从句主语we后用动词原形，④填learn（学习）。 32．如果你不快点，就会错过电影开场。 You will miss the beginning of the movie ________ you ________ hurry. 【答案】 if don’t 【详解】根据中文对照可知，第①空缺少“如果”，if“如果”，引导条件状语从句；第②空缺少“不”，if条件句中，主句用一般将来时，从句用一般现在时，而从句中已有谓语动词“hurry”，需用助动词don’t表达否定。故填if；don’t。 33．如果有人告诉你他的爱好，而且你偶尔问相关的问题，他当然会开心地继续这个谈话。 ________ ________ ________ you his hobby and sometimes you ask questions about it, he ________ ________ ________ happy to continue the conversation. 【答案】 If someone tells will surely be 【详解】根据中英文对照可知，该句为if“如果”引导的条件状语从句，遵循“主将从现”原则，句首首字母应大写；“有人”someone，作主语；“告诉”tell，主语是第三人称单数，从句时态用一般现在时，谓语动词用三单形式；主句时态用一般将来时，结构为“will do”；“当然”surely，副词作状语，置于be动词后；“开心做某事”be happy to do sth.，be动词用原形。故填：If；someone； tells； will； surely； be。 34．许多人喜欢它，因为它展现了 16 世纪意大利的生活风貌。 Many people enjoy it ________ it shows what life ________ ________ in 16th-century Italy. 【答案】 because was like 【详解】原句中“因为”和“生活是什么样的”是关键词，对于①处，中文“许多人喜欢它，因为它展现了……”，“因为”对应的英文是“because”，用来引导原因状语从句，所以①处填“because”。 对于②处，句子描述的是16世纪意大利的生活风貌，是过去的情况，“life”是不可数名词，“是”要用过去式“was” ，所以②处填“was”。 对于③处，“what life was like”是常用表达，意为“生活是什么样的”，“like”在这里是介词，意为“像” ，所以③处填“like”。 35．我喜欢它因为它能帮我了解过去。   I like it _________ it _________ me learn about the past. 【答案】 because helps 【详解】原句中“因为”和“帮”是关键词，“因为”对应连词because引导原因状语从句；“帮助某人做某事”固定搭配help sb. do sth.，主语it为第三人称单数，一般现在时谓语动词用三单形式helps。 三、句型转换 36．You will see amazing artworks if you go inside the Mogao Caves. (改为同义句) ________ you go inside the Mogao Caves, you ________ see amazing artworks. 【答案】 If will 【详解】句意：如果你进入莫高窟内部，你将会看到令人惊叹的艺术品。if引导的条件状语从句遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时表将来。同义句转换时，可将条件句提前，主句不变，因此第一空填If（句首首字母大写），第二空填will。 37．Get up early, or you will be late. (改为同义句) If you ________ get up early, you ________ ________ late. 【答案】 don’t will be 【详解】句意：早起，否则你会迟到。原句中“Get up early, or you will be late.”可转换为“If you don’t get up early, you will be late.”。if引导的条件状语从句用一般现在时，主语you是第二人称，否定形式用don’t；主句用一般将来时，will后接动词原形be。 38．There is no electricity. All high-tech devices will stop working.  (用if合并句子) → If there ________ no electricity, all high-tech devices ________ ________ working. 【答案】 is will stop 【详解】句意：没有电。所有高科技设备将会停止工作。if引导的条件状语从句遵循“主将从现”的原则，从句要用一般现在时，electricity是不可数名词，there be句型中，be动词用is，主句要用一般将来时，结构为will+动词原形，填is；will；stop。 39．You walk home and want to listen to your favourite songs. You can play them on your smart watch. （用 if 合并句子） → If you ________ ________ home and want to listen to your favourite songs, you ________ play them on your smart watch. 【答案】 are walking can 【详解】句意：你步行回家，想听你最喜欢的歌。你可以在智能手表上播放它们。本句考查if引导的条件状语从句合并句子，从句表达“你正在步行回家”，用现在进行时，结构为are + 现在分词，因此填are；walking；主句表达“你就可以播放它们”，用情态动词can表示“能够”，因此填can。 40．Without your help, I can’t finish the task on time. (if 引导条件状语从句) _______________________________________________________________ 【答案】If you don’t help me, I can’t finish the task on time. 【详解】原句句意：没有你的帮助，我无法按时完成这项任务。“Without your help” 是一个介词短语，表示“如果没有你的帮助”，是一个假设条件，“I can’t finish the task on time”是这个条件下的结果。题干要求改为if 引导条件状语从句，也就是将“Without your help”转换为if条件句。原句can’t是一般现在时，表示一种普遍事实或当前情况，因此改写后的句子也使用一般现在时态，所以将“Without your help”​改为“If you don’t help me” ​，后半部分保留原句即可。故填​If you don’t help me, I can’t finish the task on time. 一、语法选择 请通读下面短文，掌握其大意，根据语法和上下文连贯的要求，从每小题三个选项中选出一个最佳的答案，并将答题卡对应题目所选的选项涂黑。 There are many optimistic (乐观的) people around us. 1 person I have ever seen is my dad!

He is always there to give 4 encouragement and help. When I do something wrong, he always tells me 5 I should do next time in a positive way. For example, if I am 6 trouble, he often tells me to open the books he has bought for me. Then he asks me 7 the stories that can help me with the problems I’m facing. After that, we will have a discussion together. If it’s useless, he 8 me calm (镇静) down first and think about what happened to me by myself. 9 I’m not always a good kid because of my naughty (淘气) character, my dad never shouts at or gets angry with me. I know that he’s waiting for the day when I grow up and understand some important things in my life. I can see the reason why he is so positive is that he believes in himself, and also I 10 by him. He believes that whatever happens, it is under control. So we have nothing to worry about. Be positive! Sunshine will be in your life forever! 1．A．Optimistic B．More optimistic C．The most optimistic 2．A．the B．/ C．a 3．A．may B．may not C．must 4．A．mine B．me C．I 5．A．which B．what C．why 6．A．in B．of C．at 7．A．reading B．read C．to read 8．A．let B．is letting C．will let 9．A．Although B．Unless C．If 10．A．trust B．am trusted C．trusted 【答案】 1．C 2．C 3．A 4．B 5．B 6．A 7．C 8．C 9．A 10．B 【导语】本文主要讲述作者的父亲是身边最乐观积极的人，记叙父亲包容、鼓励、引导自己的种种小事，解释父亲乐观的根源是自信且信任自己，号召大家保持积极心态。 【详解】1．句意：我见过最乐观的人就是我的爸爸。 句中“I have ever seen”表示范围，三者及以上比较用形容词最高级the most optimistic。 1．句意：他如此积极乐观，我从未听过他说一句和绝望相关的话。 固定搭配a single word表示“一句话、一个字”，single以辅音音素开头，用不定冠词a。 2．句意：和大多数父母不同，爸爸从不说可能让我难过的话。 may意为“可能”，may not意为“可能不”，must意为“必须”；结合前文父亲乐观温柔，此处指不会说可能伤人的话，应用may。 3．句意：他总会给予我鼓励和帮助。 give是动词，后面用人称代词宾格作宾语，me是宾格，mine是名词性物主代词，I是主格。 4．句意：当我做错事时，他总会用积极的方式告诉我下次该做什么。 空处引导宾语从句，从句中缺少do的宾语，用what引导，what I should do意为“我应该做的事”；which表选择，why表原因，均不符合。 5．句意：比如，如果我陷入麻烦，他总会让我翻开他给我买的书。 固定短语in trouble意为“处于麻烦、陷入困境”，故选A。 6．句意：然后他让我读那些能帮我解决当下难题的故事。 固定搭配ask sb. to do sth.意为“要求某人做某事”，不定式to read作宾语补足语。 7．句意：如果这办法没用，他会先让我冷静下来，独自反思发生的事。 if引导条件状语从句，遵循“主将从现”，主句用一般将来时will let。 8．句意：虽然我生性淘气，不总是个乖孩子，但爸爸从不大吼大叫、生气。 although引导让步状语从句，意为“虽然、尽管”；unless除非，if如果，均不符合。 9．句意：我能明白他如此积极的原因是他相信自己，而且我也被他信任。 主语I和trust之间是被动关系，全文为一般现在时，一般现在时被动语态结构为“am/is/are + 过去分词”，主语是I，应用am trusted。 二、短文填空 阅读下面材料，在空白处填入1个恰当的词或括号内单词的正确形式，并将答案写在答题卡的相应位置。 I’m the eldest child in my family, so I need to set a good example 1 my two little cousins. I learned from my mother. She is my role model. Mum was also 2 (old) child in her family. She has two younger brothers. Mum was always calm, fair, and wise beyond her years. Even when Mum was only six years old, she used to 3 (share) with her brothers. If there was one piece of cake, mum would cut it into three pieces and let her brothers choose their pieces 4 (one). I do the same with my cousins. Mum says that if I do the right things, my cousins 5 (do) the right things, too. I work hard at school, and I try to be 6 (help) and kind all the time. As soon as I finish my homework, I always ask Grandma 7 I can help her with anything. Sometimes she wants me to help with the housework, but usually she just asks me to help my cousins with their homework. Sometimes, there’s a lot of 8 (stressed) in being a good role model. However, it makes me stronger. I guess I’m lucky to have Mum as 9 example. I hope that I can do as 10 (good) as Mum, and that when my cousins grow up, they respect me as much as Mum’s brothers respect her. 【答案】 1．to/for 2．the oldest/the eldest 3．share 4．first 5．will do 6．helpful 7．if/whether 8．stress 9．an 10．well 【导语】本文主要讲述了作者作为家中最大的孩子，以妈妈为榜样，努力做弟弟和表亲们的好榜样。 1．句意：我是家里最大的孩子，所以我需要给我的小表亲们树立一个好榜样。结合固定搭配set a good example to/for sb.可知，此处应用介词to/for，表示“给某人树立榜样”。 2．句意：妈妈小时候也是家里最大的孩子。结合后面的“She has two younger brothers.”和提示词old可知，此处表示“最大的”，此处与the连用，构成the oldest或是the eldest。 3．句意：即使在妈妈只有六岁的时候，她也常常和她的兄弟们分享东西。结合固定搭配used to do sth.可知，to后应用动词原形share，表示“过去常常做某事”。 4．句意：如果只有一块蛋糕，妈妈会把它切成三块，并让她的兄弟们先挑选他们的那一块。结合前面的their pieces和提示词one可知，此处用序数词first表示顺序。 5．句意：妈妈说，如果我做正确的事情，我的表亲们也会做正确的事情。结合if引导的条件状语从句可知，主句应用一般将来时，故此处填will do。 6．句意：我在学校努力学习，并且我一直努力做到乐于助人和友善。结合be后接形容词作表语以及and后的kind可知，此处应用help的形容词形式helpful。 7．句意：我一做完作业，就总是问奶奶我是否能帮她做任何事情。结合句意可知，此处引导宾语从句，表示“是否”，应用if/whether。 8．句意：有时候，做一个好榜样会有很多压力。结合a lot of后接名词以及提示词stressed可知，此处应用其名词形式stress。 9．句意：我想我很幸运有妈妈作为一个榜样。结合空后名词example可知，此处应用不定冠词an，构成an example。 10．句意：我希望我能和妈妈一样好，并且当我的表亲长大后，他们会像妈妈的兄弟们尊敬她那样尊敬我。结合固定结构as…as以及前面的“do”可知，此处应用good的副词原级well。 1 / 12 学科网（北京）股份有限公司 $
