Unit 5 重点句型学案 2020-2021学年人教版 2019 必修第一册.docxVIP

第五单元 重点句型 句型1 There are many reasons why this has been possible,but one of the main factors has been the Chinese writing system.有许多原因使这成为可能,但其中很重要的一个因素就是汉语文字系统。? 本句为并列复合句。全句由but连接前后两个分句,在前一分句中why引导的定语从句修饰先行词reasons,其中why相当于for which,在定语从句中做原因状语。 reason后接定语从句的用法 reason做先行词,后接定语从句时: (1)若关系词在从句中做状语,要用why或for which引导定语从句。? The reason why/for which he was late was that he got up late.他迟到的原因是他起晚了。 (2)若关系词在从句中做主语、宾语等,要用which或that引导定语从句。关系词做宾语时可将其省略。 He gave us a reason that/which sounded reasonable.他给了我们一个理由,这个理由听起来合情合理。(关系词在从句中做主语) The reason (which/that) he has given sounds reasonable.他给出的理由听起来合情合理。(关系词做given的宾语,可省略) 单句语法填空 (1)I told him the reason　　　　I took a great interest in the movie.? (2)Is this the reason　　　　he explained at the meeting for his carelessness in his work?? 参考答案 (1)why　句意:我告诉了他我对这部电影极其感兴趣的原因。分析句子结构可知,空处引导定语从句,且在从句中做状语,故填why。 (2)that/which/不填　句意:这就是他在会上解释的工作疏忽的原因吗?空处引导定语从句,且从句中explained缺少宾语,故用that/which或不填。 句型2 Over the years,the system developed into different forms,as it was a time when the Chinese people were divided geographically,leading to many varieties of dialects and characters.在那些年间,它已经发展为不同的形式,因为那个时候中国人是按照地域划分的,许多不同的方言和文字符号随之产生。? 本句为复合句,as前面的部分为主句。as引导的是原因状语从句,在该从句中when引导的定语从句修饰先行词a time;leading…为现在分词短语做结果状语,修饰从句的谓语动词were divided。 “It was a time when…”句型 “It was a time when…”意为“那段时间……”,为固定句式。在此固定句式中,a time是先行词,when为关系副词,引导定语从句,并在从句中做时间状语。有时也用“There was a time when…(曾经有一段时间……)”。? It was a time when girls couldn’t go to school. 那时女孩不能上学。 There was a time when he was very disappointed and wanted to leave here. 他曾经有一段时间很失望,想离开这里。 根据汉语意思完成句子 (1)有一段时间,我对他的未来感到不安。 There was　　　　　　　　　I felt upset about his future.? (2)这个国家那段时间是世界上最强大的国家之一。 　　　　　　this country was one of the strongest countries in the world.? (3)曾经有一段时间我和同学们相处得很好。 　　　　　　I was getting along well with my classmates.? 参考答案 (1)a time when　(2)That was a time when　(3)There was a time when 句型3 Emperor Qinshihuang united the seven major states into one unified country where the Chinese writing
