Using language Section Ⅲ 语法专题突破 听力发掘训练 新知深化学习 课时跟踪检测 Contents 目录 01 02 03 04 2 01 语法专题突破 语法项目——复习定语从句 语境中体悟 Isaac Asimov was an American scientist and writer who wrote around 500 books① that/which included mystery stories, science and history books, and even books about Shakespeare②.But his best­known work was his science fiction stories.Asimov had both an extraordinary imagination that/which gave him the ability to explore future worlds③ and an amazing mind with which he searched for explanations of everything in the present and the past④.Asimov's life began in Russia, where he was born⑤ on 2nd January, 1920.It ended in New York on 6th April, 1992, when he died⑥ as a result of an HIV infection that/which he had got from a blood transfusion nine years earlier⑦. [语法入门] 句①是关系代词who引导的定语从句，修饰指人的先行词an American scientist and writer； 句②是关系代词that/which 引导的定语从句，修饰指物的先行词around 500 books； 句③是关系代词that/which 引导的定语从句，修饰指物的先行词an extraordinary imagination； 句④是“介词＋关系代词which”引导的定语从句，修饰指物的先行词an amazing mind; 句⑤是关系副词where引导的定语从句，where在从句中作地点状语； 句⑥是关系副词when引导的定语从句，when在从句中作时间状语； 句⑦是关系代词that/which 引导的定语从句，修饰指物的先行词an HIV infection。 学案中理清 定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分。定语从句分为限制性和非限制性从句(与主句之间用逗号隔开)两种。定语从句的基本结构为：先行词＋关系代词或关系副词＋从句。关系词有三大作用：指代先行词；引导定语从句；在从句中充当句子成分。 一、关系代词的用法　 1．关系代词的基本用法 关系代词 先行词 句法功能 who 人 主语、宾语(限制性定语从句中可省略)、表语 whom 人 宾语(限制性定语从句中可省略) whose (＝of whom/of which) 人或物 定语 that 人或物 主语、宾语(限制性定语从句中可省略)、表语 which 物 主语、宾语(限制性定语从句中可省略) as 人或物 主语、宾语 2．五种只用that而不用which的情况 (1)先行词是不定代词all, much, little, something, everything, anything, nothing, none等或者先行词被不定代词所修饰时； Do you have anything that you want to say for yourself? 你有什么要为自己说的吗？ (2)先行词被序数词、形容词最高级或the only, the very (恰恰，正好), the last等修饰时； This is one of the most exciting football games that I have ever seen. 这是我看过的最激动人心的足球比赛之一。 This is the only thing that we can do now. 这是我们现在唯一能做的事情。 (3)先行词既有人又有物时； The scientist and his achievements that you told me about are admired by us all. 你告诉我的那位科学家和他所取得的成就为我们所有人所钦佩。 (4)当先行词在主句中作表语，而关系代词在从句中也作表语时； Shanghai is no longer the city that it used to be. 上海不再是过去的那座城市了。 (5)当主句的主语是疑问词who或which时。 Who is the person that is standing at the gate? 站在门口的那个人是谁？ 3．which与as引导非限制性定语从句时的3点区别   which as 位置 只能放在主句的后面 位置灵活，可位于句首、句中，也可置于句末 搭配 无动词的限制 从句谓语动词通常是表示感觉或心理活动的动词，如see, hear, know, expect, remember等 意思 意为“这一点” 表示“正如……，正像……的那样” [对点练] (1)单句语法填空 ①(2025·全国Ⅰ卷)An exhibition at the Jiushi Art Museum in Shanghai is featuring artwork inspired by Go, or weiqi in Chinese, _______originated in China more than 4,000

For the study, researchers collected data from 968 young adults born between the years 1981 and 1996, starting when they were freshmen in college.They followed up with the same students when they were seniors, and then two years later.The study participants answered questions about materialism，their own personal finance strategies such as budgeting and any pro­-environmental habits they followed.Students were also surveyed about their mental health, including how satisfied they were with their lives and how they'd rank their personal well­-being. “People who save money report better overall well­-being，including less psychological pain，”Sabrina Helm，study author tells CNBC Make It.“And people who buy less and consume less show less depressive symptoms，so there's a positive mental health effect.” Not surprisingly，the money­saving strategies improved people's financial satisfaction too.“It gives you peace of mind，” Dr Helm says.“If you're able to put something aside for worse days, and manage to live within your means，it has clear positive effects on mental health.” Certain sustainability efforts also have a similar impact on people's health and happiness.For example，researchers found that the students who consumed less to help the environment were happier than those who simply bought more “green” products.Although many people have been socialized to see products as solutions，simply reducing the number of things you use or buy might be the better tactic for your mental health, Dr Helm explains. “It's normal to get a product to cope with all sorts of things，” Dr Helm says，“but that contributes to climate change.” Luckily，there are concrete tips to “step back from the consumerist approach”，she adds.For example，she suggests keeping a weekly purchase diary and creating a shopping list. 语篇解读：本文是一篇说明文。一项新的研究结果表明，采用积极财务策略以调整自己购买习惯的“千禧一代”，不仅能更合理地规划自己的财务支出，而且收获了个人身心健康等方面的益处。 解析：推理判断题。根据第二段的内容可知，研究者一直在追踪同一批受试者，通过询问、调查等具体方式收集数据。 √ 1．How was the study conducted?

A．Consuming less cures people of depressive symptoms. B．Mentally healthier people buy more and consume less. C．Saving money prevents people from psychological disorders.
