Period 2　Learning About Language 1 复习长难句 返回导航 要义详析 探究语法 1 课堂微练 即时检验 2 内 容 索 引 要义详析 探究语法 PART 01 第一部分 4 英语中的句子按其结构可分为三种类型：简单句、并列句、复合句。英语长难句通常含有较多、较长的修饰成分或包含多个并列句或从句，理解起来较为困难。 返回导航 一、长难句的类型 (1)(教材P50)As an adult, one of the first questions you are asked when meeting someone new is, “What do you do？” 作为一名成年人，你结识新朋友时首先被问及的问题之一是：“你是做什么工作的？” (2)(教材P50)This is because your career is a very important part of who you are.　这是因为你的职业是你身份的一个非常重要的组成部分。 (3)(教材P50)Some people know what they want to do from a young age, but many others just have a few ideas bouncing around in their heads. 有些人年轻时就清楚自己想做什么，但更多的人只是有一些想法在脑子里晃来晃去。 返回导航 复合句包括主从复合句和并列复合句。 1．主从复合句是由一个主句和一个或多个从句构成的句子。从句主要包括名词性从句、定语从句和状语从句。 2．并列复合句指并列句、复合句混合在一个句子里，或者说，一个句子里包含着多种关系：既有并列关系，又有复合关系。 返回导航 二、长难句的突破策略 1．据谓语，找主语 一般情况下，一个谓语动词对应其动作的发出者(主语)，可以根据谓语动词的意义来确定其主语。而且，如果一个句子中出现两个或两个以上的谓语形式的动词，则该句可以是并列句或复合句(并列谓语动词的情况除外)。 返回导航 *(2024·新高考全国卷Ⅰ) If he seems a little defensive, it might be because even some of his coworkers occasionally laugh at his unusual methods. [分析]　“If he seems a little defensive”是条件状语从句，seems是系动词，主语是he，a little defensive 作表语；“it might be because even some of his coworkers occasionally laugh at his unusual methods”中谓语动词是might be，it是主语； 在because引导的表语从句中，谓语动词是laugh at，主语是some of his coworkers。 [翻译]　如果他看起来有点防备心，这可能是因为即使是他的一些同事偶尔也会嘲笑他的不寻常的方法。 返回导航 2．提主干，去枝叶 一般情况下，一个句子中的主句所表达的信息为主要信息，从句、状语和定语等所表达的信息为次要信息。若句子的主干提炼不出来，就不能完全把握句子的核心意义，从而导致思维混乱、主次不分。 返回导航 *(2023·新高考全国卷Ⅱ)Naming each nature experience creates a usable language，which helps people recognize and take part in the activities that are most satisfying and meaningful to them. [分析]　“Naming each nature experience creates a usable language”是句子的主干。“which helps people...meaningful to them”是非限制性定语从句，修饰先行词language；“that are most satisfying and meaningful to them”是定语从句，修饰先行词activities。 [翻译]　命名每一种自然体验都会创造出一种可用的语言，这种语言帮助人们识别并参与对他们来说非常满意、非常有意义的活动。 返回导航 3．寻关联，辨逻辑 一些长句其实是由若干分句组成的并列句或复合句。而这些并列句或复合句之间需要关联词来连接。如果找准这些关联词，就能够弄清楚句子之间的逻辑关系，分别弄清主句的意义和从句的意义，对长句的理解就容易得多了。要掌握此方法必须对英语中常见的关联词谙熟于心。 返回导航 *(2024·全国甲卷) That's why most pet cats are able to tell immediately if their owners were around any other cats, which they don't usually like. [分析]　“That's why most pet cats are able to tell immediately”是句子的主干；“why most pet cats are able to tell immediately”是表语从句，说明that所指代的事情的原因；“if their owners were around any other cats”是宾语从句；“which they don't usually like”是非限制性定语从句，修饰先行词any other cats。 [翻译]　那就是为什么大多数宠物猫能够立即察觉它们的主人是否接触过其他猫，而它们通常并不喜欢这样。 返回导航 4．看搭配，防分隔 有时一个长句是由一个或多个搭配构成，而这些搭配中常常出现分隔现象。若受到这种分隔现象的干扰，无法清晰地洞察句子的原本结构，那么对句子含义的理解就可能产生偏差。 返回导航 *(2024·新高考全国卷Ⅰ)According to this theory, people approach digital texts with a mindset suited to social media, which are often not so serious, and devote less mental effort than when they are reading print. [分析]　“people approach digital texts with a mindset suited to social media...and devote...”是句子的主干，approach和devote并列作谓语；“with a mindset suited to social media”是介词短语作状语，“suited to social media”是过去分词短语作后置定语，修饰mindset；“which are often not so serious”是非限制性定语从句，修饰先行词social media，对社交媒体的特点进行补充说明；“when they are reading print”是时间状语从句，与前面阅读数字文本时的情况进行对比。 返回导航 [翻译]　根据这一理论，人们以一种适合社交媒体(社交媒体往往不是那么严肃)的心态去接触数字文本，并且与阅读纸质文本时相比，他们投入的脑力更少。 返回导航 课堂微练 即时检验 PART 02 第二部分 17 Ⅰ.辨别下列各句的类型 1．And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the States.___________ 2．All we need is a small piece of land where we can plant various kinds of fruit trees throughout the growing seasons of the year.___________ 3．They'll swear that they left it in the changing room，create havoc and then discover it had been in their car all the time.___________ 主从复合句 主从复合句 主从复合句 返回导航 4．Nick's mother-in-law lives on the ground floor，while Nick lives upstairs with his wife and their two daughters.___________ 5．Yet the researchers suggest that single parents still may play a role in teaching the benefits of persistence，which is an avenue of future research.___________ 6．Having never operated a computer, Mr.Johnson met with a lot of difficulties at first.___________ 7．People feared that weakening a 21-year-old ban on the sale of ivory would encourage illegal hunting and hurt elephant populations.___________ 并列句 主从复合句 简单句 主从复合句 返回导航 8．My brother and I go to school at half past seven in the morning and come back home at seven in the evening.___________ 9．It was a trait others found helpful，and I soon had friends who wanted to make things with me.___________ 10．She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them.___________ 简单句 并列复合句 主从复合句 返回导航 Ⅱ.语法与写作(句型转换) 1．I once participated in an internship in a multinational enterprise during my university.It was a head start for me.(改为含有定语从句的复合句) ________________________________________________________________________________________________________________________ 2．Maya society was technologically primitive.The fact makes its achievements all the more incredible and mysterious.(改为含有同位语从句的复合句) ________________________________________________________________________________________________________________________ I once participated in an internship in a multinational enterprise during my university, which was a head start for me.
