2020届二轮复习三大从句课件（82张）

2020 届二轮复习主从复合句 1. 主语从句作主语，主句谓语动词通常用 单数；为使句子平衡，常用 it 作形式主语。 2. 表语从句还可以用 as if ， as though 引导。 3. 表示“是否”，引导宾语从句时可用 if 或 whether ，但在介词后或直接与 or not 连用时，只能用 whether 引导；引导表语从句、同位语从句或位于句首的主语从句时，只 能用 whether ，不用 if 。 要点： 4. 同位语从句一般放在 fact ， news ， idea ， promise ， suggestion ， advice 等抽象名词之后，说明或解释这些抽象名词的具体内容。多用 that 引导，不能由 which 引导。 5. 当宾语从句又带有补语时，要用 it 作形式宾语。 6. 在表示“建议” “命令” “要求”，如 advice ， suggestion ， proposal ， order ， demand ， request 等词后的名词性从句，其谓语通常 用“ (should ＋ ) 动词原形”。 7. that 引导名词性从句时，没有任何意义，也不作任何句子成分；但 that 引导定语从句时，它代表先行词，而且在从句中作主语、宾语或表语。如： I still remember the promise that he made . 我依然记得他许下的诺言。 ( 定语从句 ) The naughty boy made a promise that he would never make a noise . 那个淘气的孩子保证说他以后再也不吵闹了。 ( 同位语从句 ) 熟读深思 What worries my classmate Mary a lot these days ［ 1 ］ is that she puts on too much weight and she is frequently ill ［ 2 ］ . She has some doubts whether she eats too much fast food high in fat or sugar ［ 3 ］ . Also, with the college entrance examination approaching, she becomes more stressful and she couldn’t sleep well these days. Maybe this is also the cause that she becomes fatter these days ［ 4 ］ , she thinks. How she becomes slimmer and healthier ［ 5 ］ has been her main task. So she wants to consult some experts and gain some instructions. But where she could get better suggestions and who will give her better advice ［ 6 ］ also puzzle her. It is her parents’ suggestion that she should consult Professor Wang in Zhongshan Hospital ［ 7 ］ . Professor Wang suggests that she keep a balanced diet first ［ 8 ］ . She should eat vegetables and fruit high in fiber, vitamin and protein. What’s more, if she wants to lose weight, she had better take regular exercise more than half an hour a day. Mary asked Professor Wang when she should take exercise ［ 9 ］ . Professor Wang advised her to take exercise at 5 o’clock in the afternoon because she will have more time to do sports. Thanks to Professor Wang, Mary has become much healthier now. 汉语译文： 我的同学 Mary 感到很焦虑是因为这一段时间胖了很多而且经常生病。她怀疑她是否吃了太多含有高脂肪或高糖的快餐。而且高考将近 , 她的心理压力很大，所以这几天总是睡不好。 她想这也有可能是造成她变胖的原因。她怎样可以变得苗条些和更健康些变成她的主要任务了。所以她想通过咨询专家来获得一些指导。但她去哪里咨询和要咨询谁又让她感到很困惑。她的父母建议她去中山医院咨询王教授。王教授建议她首先要保持均衡的饮食，应多吃富含纤维、维他命、蛋白质及新鲜的蔬菜和水果。当然，如果她想要减肥，最好还是要每天坚持运动半个小时以上。 Mary 问王教授哪一个时间段适合她去运动。王教授建议她下午 5 点后去运动，因为她这时是有充足的时间来运动的。多亏王教授， Mary 现在健康多了。 熟读深思 1. 主语从句。 What (=the thing that) 在主语从句中作主语。 2. 表语从句。从句本身意思完整，也不缺任何句子成分，所以用 that 引导。 3. 同位语从句。补充说明 doubt 的具体内容，因 doubt( 疑惑 ) 的意思本身是不确定的，故由 whether 引导。 4. 同位语从句。说明 the cause 的具体内容。 5. 主语从句。表示“如何”变得苗条些和更健康些。 6. 主语从句。去哪里咨询、向谁咨询，故分别由 where, who 引导。 7. 同位语从句。说明 suggestion 的具体内容，从句内容完整也不缺任何句子成分，故由 that 引导。 8. 宾语从句。从句内容完整也不缺句子成分，故由 that 引导。 9. 宾语从句。 when 在从句中作时间状语。 状语从句 1. 在时间状语或条件状语从句中，通常用一般现在时代替一般将来时，用现在完成时代替将来完成时。 2. 辨析： when ， while ， as 引导时间状语从句。 while 必须与延续性动词连用，强调主句动作延续到从句所指的整个时间时，只能用 while ；表示“随着” 只能用 as ；表示有规律的“每当” 时或主句动作与从句动作有先后时，只能用 when 。 要点： 3. 辨析： because ， since ， as 引导原因状语从句。 because 语气最强，表示直接的原因，是说话人认为对方不知道的原因，它引导的从句通常位于主句之后；在回答 why 时，或者在强调结构中，只能用 because 。 since 和 as 是对大家已知的事实提供理由或背景，它们引导的从句多位于主句前，有时也位于主句后。 4. as 引导让步状语从句时，从句中的状语、表语或动词必须置于句首； though 引导让步状语从句时，这些成分可置于句首也可用正常语序；但 although 等其他词引导的让步状语从句不能将这些成分前置。 5. 表示“虽然” 的连词不能与表示“但是” 的连词 but 连用； 表示“原因” 的 because 等连词不可与表示结果的连词 so 等同时使用。 熟读深思 My mother was cooking in the kitchen while ［ 1 ］ I was doing my school assignments. As soon as ［ 2 ］ I finished my homework, I went to get some water to drink. Then the door bell rang. However, my sister unlocked the door before ［ 3 ］ I could open it. We were surprised the moment ［ 4 ］ we saw her because ［ 5 ］ her clothes and face were terribly dirty. She looked much poorer than ［ 6 ］ we expected. Since ［ 7 ］ we didn’t know what had happened to her, we stood there and waited for my sister’s story . We wouldn’t leave unless ［ 8 ］ my sister told us all about it. After ［ 9 ］ my sister got changed, she told us that she fell into a ditch when ［ 10 ］ she walked on a path on her way to my uncle’s home in the countryside . She couldn’t get out of the ditch. Although ［ 11 ］ she cried for help loudly, no one could hear her. She tried to climb out of it, but, however ［ 12 ］ hard she tried, she failed to escape from it. As ［ 13 ］ time went by, she got worried. After several vain attempts she had to stand where ［ 14 ］ she was and waited until ［ 15 ］ a boy student passed by and gave her a hand. The boy reached her a long rope and told her to climb with the rope. She did as ［ 16 ］ the boy told , so that ［ 17 ］ she came out. My sister also warned us to be careful when ［ 18 ］ walking on a path even though/if ［ 19 ］ we are in a great hurry. That’s true. We should mind our step so that ［ 20 ］ we can ensure our safety. 汉语译文： 我妈妈在厨房做饭，而我在做作业。我一做完作业就去拿水喝，这时门铃响了。然而，我还没来得及打开门，我的妹妹就用钥匙打开了门。我们看见她时，非常惊讶，因为她的衣服和脸非常脏。她看起来比我们预料的更可怜。因为我们不知道发生了什么事，我们站在那，等着我妹妹说她的故事。除非我妹妹告诉我们有关的一切，否则我们是不会离开的。 我妹妹换了衣服之后，就把一切都告诉了我们。她去乡下叔叔家的路上不小心掉进了一个水沟里，而且上不来。虽然她大声求救，但是没有人能听到。她试图爬出来，但是无论她怎么努力，都没能爬出来。时间一分一秒过去，她开始担忧起来。经过几次徒劳的尝试之后，她只好站在原处等。直到一个男孩经过，帮助了她。男孩把一根长绳索递给她并叫她拉着绳子爬上来，她按男孩所说的去做，结果就爬出来了。我妹妹也警告我们，即使要赶时间，走小路时也要小心。的确，我们走路要小心，这样才能确保我们的安全。 1. 用于对比两件事，意思是“而 ……” 用 while ，不能用 when/as 代替。 2. as soon as 引导时间状语从句 , 表示“一 …… 就 ……” 。 3. before 表示“还没来得及就 ……” 。 4. 名词词组如 the moment/ the second/the day/ the first time/next time... 等可以用来引导时间状语从句。 5. 引导表示原因的从句时用 because, 引导原因状语从句时一般放在主句之后 , 而如果只是名词性短语表示原因 , 则用 because of 。 熟读深思 6. 在表示比较级中，用 than 来引导比较状语， than 也可以作介词。 7. 对大家已知的事实提供理由或背景时 , 常用 since 引导，意思是“既然”。其引导的从句多在主句之前。 8. 引导条件状语从句， unless=if ... not 是“除非，如果不”之意。 9. 引导表示时间先后的状语从句时 , 用 after/ before 来表示，根据实际表达需要选用其一。 10. when 引导表示“当 …… 时”的时间状语。 11. 引导让步状语从句时，可以用 although 或 though ，主句可以与副词 still 连用，但不能再与连词 but 连用了，一个复合句只需一个连词。 当是 as 引导让步状语从句时，从句中的状语、表语或动词置于句首。 12. however 引导让步状语从句时 , 其后常接形容词或副词用于修饰该形容词或副词 , wherever, whenever 也可以引导让步状语从句 , 在从句中作状语 , 相当于 no matter how/ where/ when, 另外 whatever, whoever, whichever 也可以引导让步状语从句。 13. 表示“随着”时，只能用 as 引导。 14. 引导地点状语从句时 , 用 where/wherever ，表示“在 …… 的地方”。 15. 固定用法“直到 …… 才 ……” 可以用两种表达形式：“延续性动词 +until+ 句子” ( 用肯定形式 ) ；“ not+ 短暂性动词 +until+ 句子” ( 用否定形式 ) 。 16. 引导方式状语从句时，可以用 as ，意思是“按照， 像 …… 那样”。 17. so that 引导结果状语从句，从句表示的通常是某件事的结果。 18. when 引导表示“当 …… 时”的时间状语时，如果主句的主语和从句的主语是一致时，可以省略 when 从句的主语和 be 动词，用分词来表示。 19. 表示“即使，尽管”的 even though/if 引导让步状语从句。 20. so that 除了引导结果状语从句，还可以引导目的状语从句，常与情态动词 can/could 等连用。 定语从句 要点： 1. 在限制性定语从句中 which, who, whom 都可用 that 代替。关系代词作宾语时常被省略。 2. 在非限制性定语从句中，或者当先行 词是指人的 those ， anyone ， everyone ， people, he ， all ， few ， one(s) 等时，不能 用 that 引导。 3. 以下情况下一般用 that ： ⑴ 当先行词是指物的 all ， little ， few ， much ， any ， anything ， everything ， nothing ， none ， the one 时，或先行词被 all ， little ， few ， much ， any ， every ， no 等修饰时。 ⑵ 先行词是序数词或最高级形容词时，或者先行词被序数词 ( 包括 last ， next) 、最高级形容词及 the only ， the very 等修饰时。 ⑶ 先行词包括人和物时。 4. 当先行词是表示时间、地点、原因 ( 且只能是 reason) 等，且这些先行词在定语从句中作状语时，就分别用 when 、 where 、 why 来引导定语从句。另外， when ， where, why 一般可用“介词 +which” 替代，其中 reason 后的 why 通常用 for which 替代。 当先行词是表示时间、地点或 原因的词语时，不一定填关系副词 when ， where ， why ，只有当这些 词在定语从句中作状语时，才用关 系副词，否则要用关系代词。 特别提醒： 5. 当先行词是整个主句或主句的一部分时，这类非限制性定语从句只能由 which 或 as 来引导。两者的区别在于： ⑴ which 引导的定语从句只能位于主句后，而 as 引导的定语从句可位于主句前、中、后。 ⑵ which 常译作“这”；而 as 常译作“正如”，且多与 see ， expect ， imagine ， know ， hope 等动词连用。 ⑶ 在定语从句中作主语时，若用 as ，其谓语部分一般有 be ；若谓语是不含 be 的行为动词时，要用 which 。 ⑷ as 引导的定语从句只表示一个众所周知或意料之中的事，而 which 不受此限制。 ⑸ as 常用于固定搭配中： as is often the case( 这是常有的事 ) ； as we expected( 不出所料 ) ； as often happens( 正如经常发生的那样 ) ； as is known to all( 众所周知 ) ； as has been said before( 如上所述 ) ； as is mentioned above( 正如上面所提到的 ) ；等等。 熟读深思 It was the summer of 2012 , when ［ 1 ］ I came to Guangning No.1 Senior High School. Our school is a wonderful place , where ［ 2 ］ I can see a lot of beautiful buildings and a large square. Our classroom , the roof of which ［ 3 ］ looks like a rocket in the distance, is located in the center of our school. The main reason why ［ 4 ］ I like our school is that I can make many friends. I can get along with my classmates here , two of whom ［ 5 ］ are my best friends. Jack , who ［ 6 ］ comes from Tanbu Junior High School, is very active. He likes various sports , among which ［ 7 ］ he likes running very much. He will run 5 kilometers every day , which ［ 8 ］ makes him look strong. Nick, whose ［ 9 ］ father is a teacher in Lianhe Junior High School, studies very hard. We often talk about the people and the things that ［ 10 ］ we see in our school. Nick prefers the food that ［ 11 ］ is made in our canteen. The teacher whom ［ 12 ］ he likes is Mr. Zhang, our math teacher, while my beloved teacher is my English teacher, Miss Chen. To be honest, I gradually fall in love with our school. 我是在 2012 年的夏天来到广宁一中读书的。我们学校环境优美，在这里我可以看见一栋栋的高楼大厦和一个宽阔的广场。我们班位于学校的中心，远远看去我们班的屋顶就像一枚火箭。但我真正喜欢这个学校的原因是我在这里结交了很多朋友。我跟我的同学相处得很融洽，其中两个是我最要好的朋友。 Jack 来自潭布中学，他很活跃。他喜欢各种各样的运动 , 当然他最喜欢的是跑步。他每天都坚持跑 5 公里 , 这使他看起来很强壮。而 Nick 学习非常用功，他的父亲是联和中学的一名教师。我们经常在一起谈论我们学校的人和事情。 Nick 喜欢我们学校饭堂的饭菜。他最喜欢的老师是数学老师张老师，而我最喜欢英语老师陈老师。说真的，我已经慢慢地喜欢上我们的学校啦。 熟读深思 本文作者叙述了来到广宁中学读书后的所见所闻。 1. 先行词是 the summer of 2012 ，在定语从句中作时间状语，用关系副词 when (=in which, during which) 引导定语从句。 2. 先行词是 a wonderful place, 在从句中作地点状语 , 用关系副词 where (=at which) 引导定语从句。 3. 先行词是 Our classroom, 直接在介词 of 后作其宾语 , 先行词是物时 , 只能用 which 。 the roof of which 中的 of 表所属关系 , 意为“我们的教室的屋顶”。 4. 先行词是 the reason ，在定语从句中作原因状语，只能用 why 引导。 5. 先行词是 my classmates ，直接在介词 of 后作其宾语，先行词是人时，只能用 whom 。 two of whom 中的 of 表示部分与整的关系，意为“我的同班同学中的两个人”。 6. 先行词是 Jack ，在定语从句中作主语，用 who 引导。 7. 先行词是 various sports ，直接在介词 among 后作宾语，只能用 which 。 8. 先行词是 He will run 5 kilometers every day 整个句子，并在从句中作主语，用 which 引导。 9. 先行词是 Nick ，在从句中作定语，表示 Nick’s ，用 whose 引导。 10. 先行词是 the people and the things ，既包括人又包括事物，通常只用 that 引导。 11. 先行词是 the food ，在定语从句中作主语 , 故用 that 或 which 引导。 12. 先行词是 the teacher ，在定语从句中作 likes 的宾语，故用 whom 引导。 主从复合句与高考 1. 主从复合句是高考语法填空的必考点，也是写作中必用的表达手段。 解题方法：当空格前后都是句子 ( 一个主谓关系算一个句子 ) ，且这两个句子之间没有关联词时，应填关联词；若其中一个句子是作整个句子的一个成分，如定语、状语 ( 如时间、地点、原因、条件、让步等 ) ，或者主语、宾语、表语、同位语等时，就要填引导从句的关联词。 根据一个句子在整个句子中所作句子成分确定从句类型后，就根据该类从句的关联词的使用特点确定具体的关联词。 2. 短文改错中，常见错误有连词的多用或少用以及误用。如用 that 引导非限制性定语从句， after 与 before 错用，导致逻辑错误等。 1. ___he thought he could escape attention by sitting at the back, he was wrong. 因 he thought… 与 he was wrong 是两个句子，且两者之间没有关联词，必定是填关联词；根据两句之间的逻辑关系，应填表示条件的 If 。意为“要是他认为坐后排可以逃避老师的注意，那他就错了”。 If 一、单句填空 用适当的连词填空。 灵活运用 2.

Exactly how the tomato was introduced into Europe is uncertain, but it was probably around 1565. how→ when 由 1565 可知，不能确定的是番茄被引入中国的“时间”，故用 when 引导主语从句，在从句中作时间状语。 2. Grandma pointed to the hospital and said, “That’s when I was born.” when→ where 医院应是她出生的“地点”，故用 where 引导表语从句，在从句中作地点状语。 3. “Every time you eat a sweet, drink green tea.” This is that my mother used to tell me. that→ what 意思是“这就是我兄弟以前常常跟我说的”，在表语从句中作 tell 的宾语，故用连接代词 what 。 4.

This is how about seventy-one percent of its surface is covered by water. how→ why 因“ 71% 的地表为水所覆盖”是“地球看起来是蓝色”的原因，故用 because 引导表语从句。请比较： About seventy-one percent of its surface is covered by water 。 This is why the earth looks blue from space. 6. It suddenly occurred to him he had left his keys in the office. 在 he 前加 that 句中 it 作形式主语， that 引导主语从句。 7.

It doesn’t matter if you pay by cash or credit card in this store. if→ whether 因 whether...or…( 不管 …… 还是 ……) 是固定搭配。 9. Our teachers always tell us to believe in that what we do and who we are if we want to succeed. 去掉 that 因句中已有连接代词 what 引导宾语从句并在从句中作 do 的宾语了。 10. When the news came how the war broke out, he decided to serve in the army. how→ that 因 the war broke out 是 the news 的同位语从句，从句的结构和意义已完整了，故用 that 引导。 Ⅱ. 状语从句 1. He can’t come because of he is ill. 去掉 because 后的 of 因 because of 是介词，而 because 才是连词， he is ill 是句子，要用连词。 2. She studied hard so that could catch up with others. 在 that 后加 she 因 so that 引导目的状语从句，从句要有主语。 3. Only we keep optimistic can we succeed. 在 only 后加 when 因 only 后接的是一个状语从句，需要有连词，根据句意，用 when 。 4. When he hesitating, a man came up to him. 在 he 后加 was 状语从句的谓语不完整，需加 was 构成过去进行时。 5. Although she was in poor health, but she continued to carry out her duties. 去掉 but 在让步状语从句中， although 不与 but 连用。 6. I will stick to my plan if you agree with me or not. if→ whether 表示“无论，不管”，用 whether…or… 引导让步状语从句。 7. I lived in this house since I came to this city. 在 lived 前加 have 因 since 引导时间状语从句，主句用现在完成时。 8. I had hardly got home than it began to rain. than→ when 表示“刚 …… 就 ……” ， hardly…when 与 no sooner…than ，不可混用。 9. We left in so a hurry that we forgot to lock the door. so→ such 因修饰名词 hurry ，用 such 。 10. He came in quietly in order to he wouldn’t wake his wife. to→ that 因 in order to 后接动词原形 , 如后接从句，则用 in order that 。 Ⅲ. 定语从句 1.
