外研版新版必修一UnitFour(Friendsforever)语法讲解
1essonFour1定语从句的定义与分类在复合句中，修饰某一名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。
根据定语从句与先行词的关系，定语从句可分为限制性定语从句和非限制性定语从句。
前者紧跟先行词，主句与从句不用逗号分开，从句不可省去；后者主句与从句之间用逗号分开，起补充说明作用，如果省去，意思仍然完整。
2.关系代词的用法(I)WhO的用法：WhO指人，在从句中可作主语、宾语和表语。
(2)whom的用法：WhOm指人，在从句中作宾语，此时也可用WhO代替。
(3)whose的用法：whose既可指人也可指物，在从句中修饰名词作定语，相当于所修饰成分的前置所有格。
它可以转化为“the+名词+ofWhiCh/whom"和"ofwhich/whom+the+名词”的形式。
(4)that和which的用法①WhiCh指物，that既可指人也可指物；它们在从句中作主语、宾语或表语，WhiCh 和that在从句中作宾语时可以省略。
②在限制性定语从句中，关系代词指物时只能用that而不用which的情况a.当先行词是a11,1itt1e,few,none,anything,something,everything,nothing等词时。
b.当先行词是序数词或形容词最高级或被序数词或形容词最高级修饰时。
c.当先行词被theon1y,thevery,thesame,theright等修饰时。
d.当先行词既有人又有物时。
③句中其他位置已出现与关系代词相同的疑问词时，应避免重复。
难点分析一：(I)Whatif用于提出假设时，意思是“倘若……，假若……怎么办，要是……将会怎么样”，其后句子可用陈述语气(一般现在时)，也可用虚拟语气(一般过去时或ShOUk1+动词原形；若是针对过去情况，从句则用过去完成时)。
(2)Whatif表示邀请或建议时，意思是“……怎么样？如果……如何？”。

外研版高一英语必修一u4知识点Unit 4 Knowledge Points from New Standard English for Senior High SchoolI. IntroductionEnglish plays an essential role in our lives today. It has become a global language, facilitating communication across cultures. In the New Standard English for Senior High School (外研版高一英语必修一), Unit 4 covers various knowledge points that are crucial for high school students. In this article, we will explore some of the key concepts and skills emphasized in this unit, discussing vocabulary, grammar, and language functions.II. VocabularyExpanding one's vocabulary is fundamental to improving language proficiency. Unit 4 introduces new words and phrases that revolve around the theme of "Global Warming". It familiarizes students with terms like fossil fuels, greenhouse effect, carbon emissions, and renewable energy. Understanding these words not only helps students comprehend related texts but also enables them to discuss environmental issues confidently.III. GrammarGrammar lays the foundation for accurate language use. Unit 4 focuses on the present perfect tense, a versatile tense that expresses actions or states that occurred in the past but still have relevance to the present. Students learn to form and use the present perfect tense to describe experiences, changes, and achievements. Additionally, the unit also teaches students howto use "yet", "already", and "ever" in questions and negative statements. This grammar point enhances students' ability to express themselves in a clear and precise manner.IV. Language FunctionsLanguage functions refer to the specific purposes for which language is used. Unit 4 emphasizes two crucial language functions: talking about cause and effect and expressing purpose. Students learn to use appropriate connectors such as "because", "so", and "although" to discuss the relationship between events or phenomena. They also explore how to express purpose using phrases like "in order to" and "so that". These language functions enable students to convey ideas effectively and coherently.V. Reading ComprehensionUnit 4 provides a variety of reading materials to improve students' reading comprehension skills. The texts cover different formats, including news articles, interviews, and informative passages. By reading these texts, students gain valuable insights into global warming and its impact on the environment. They learn to identify main ideas, infer information, and analyze the author's perspective. Through guided activities, they develop critical thinking skills and enhance their ability to grasp the main points of a text.VI. Speaking and WritingUnit 4 emphasizes speaking and writing skills, allowing students to practice using the language in meaningful contexts. Through pair or groupwork, students engage in discussions, debates, and role-plays related to environmental issues. These activities foster collaborative learning and encourage students to express their opinions, build arguments, and listen actively to others. The unit also provides writing tasks that require students to write formal letters, reports, and articles. By honing their speaking and writing skills, students develop effective communication strategies for various real-life situations.VII. ConclusionUnit 4 of the New Standard English for Senior High School offers invaluable knowledge for high school students in their English language learning journey. By focusing on vocabulary, grammar, language functions, reading comprehension, speaking, and writing, this unit equips students with the necessary tools to become proficient English users. Mastering these knowledge points enables students to express themselves fluently, understand a wide range of texts, and navigate different communication situations. With continued practice and dedication, students will further enhance their language skills and achieve success in their academic and personal pursuits.。

定语从句定语从句在句中作定语,修饰名词或代词,被修饰的名词或代词被称为先行词。
定语从句通常跟在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词有:who, whom, whose, that,which等。
关系副词有:when, where, why等。
1. 关系代词引导的定语从句：关系代词所代替的先行词是表示人或物的名词或代词,并在从句中充当主语、宾语等成分。
关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。
(1) who, whom, that这些词代替的先行词是表示人的名词或代词,在从句中作主语或宾语。
如:He is the right person who I want to find for my film.(2) whose 用来指人或物,只用作定语。
若指物时,它还可以用n.+ ofwhich结构来替换。
如:Please pass me the book whose cover is torn.Please pass me the book the cover of which is torn.Please pass me the book of which the cover is torn.(3) which, that所代替的先行词是表示物的名词或代词,在从句中可作主语、宾语等。
如:Italy is a famous city which has a lot of buildings.2. 关系副词引导的定语从句:关系副词前的先行词是表示时间、地点或理由的名词,when, where, why等引导的从句在句中作状语。
关系副词的含义相当于"介词+ which"结构。
如:Beijing is the place where(in which) I was born.Is this the reason why (for which) he refused our offer?3. 判断关系代词与关系副词(1) 用关系代词,还是关系副词取决于从句中的谓语动词。

现在完成时和一般过去时区别： 1. 一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作;现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。
2. 一般过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语：yesterday, last week，…ago, in 1980, in October, just now等，皆为具体的时间状语。

(强调看的动作发生过了) I have seen this film. 我看过这部电影。

如：汤姆昨天晚上给他父母写了一封信。
(错)Tom has written a letter to his parents last night. (对)Tom wrote a letter to his parents last night.。
