Unit 5 What a delicious meal! Section B ( 1a-3c )知识点精讲精练 重点词汇解析 1. Food for Thought发人深省的事 整体结构：这是一个由 “名词 + 介词 + 名词” 构成的固定短语​ Food：此处为不可数名词，并非 “食物” 的本义，而是抽象化为 “值得关注的内容、素材”。​ for：介词，表 “用于、为了”，连接前后名词，说明 “内容的用途”​ Thought：不可数名词，意为 “思考”，体现 “引发思考” 的含义。​ 短语意思：“引人思考的内容；发人深省的事”。​ 名词的抽象化用法： 普通名词（如 food）在特定搭配中表示抽象概念。​ “for” 的功能：表示 “对象或用途”，类似结构有 “a tool for cutting（切割用的工具）”。​ 即学即练： 请用 “名词 + for + 名词” 结构补全句子，每空一词（均为初二基础词汇）。​ The video has useful _______ for _______ (知识；学习).​ These pictures are nice _______ for _______ (东西；画画).​ The book provides new _______ for _______ (想法；讨论).​ 2. Cooking is love made visible. 烹饪是可见的爱 句子成分：这是一个主系表结构的简单句。​ 主语：Cooking（动名词），由动词 cook 加 - ing 构成，表示 “烹饪” 这一抽象行为，作主语时谓语用单数。​ 系动词：is（be 动词的第三人称单数形式），连接主语和表语。​ 表语：love（名词），表示 “爱”，是句子描述的核心对象。​ 后置定语：made visible（过去分词短语），修饰表语 love。​ made 是 make 的过去分词，表被动（“被使得”）；visible 是形容词（“可见的”），构成 “过去分词 + 形容词” 结构，说明 “love 被变得可见”。​ 过去分词作定语： 定义​ 过去分词（v-ed）作定语时，修饰名词或代词，通常表示 “被动” 或 “完成” 的含义，即被修饰的人或物是动作的承受者，或动作已完成。位置及用法​ 前置定语：单个过去分词通常放在被修饰词的前面。​ 例句：a broken cup（一个破杯子）​ 后置定语：过去分词短语（过去分词 + 其他词）通常放在被修饰词的后面。​ 例句：the book written by Lu Xun（鲁迅写的书） （解析：“written by Lu Xun” 是过去分词短语，修饰 book，表 “被鲁迅写的”。）​​ 过去分词与被修饰词的关系是 “被动”，如 “boiled water”（开水）= 水被煮沸过。​ 区分现在分词（v-ing）和过去分词（v-ed）作定语：​ 现在分词表 “主动、进行”（a running boy 一个正在跑步的男孩）；​ 过去分词表 “被动、完成”（a stolen bike 一辆被偷的自行车）。​ 即学即练： 用括号内动词的过去分词形式填空。​ 1. The _______ (lose) key was found under the desk.​ 2. We visited a _______ (close) factory last week.​ 3. She is reading a story _______ (write) by her mother.​ 4. The _______ (break) window needs to be repaired.​ 3. That is what my grandmother always told me. 这是我祖母一直告诉我的话。 表语从句​ 表语从句是在主系表结构中，位于系动词（be, look, seem, become 等）之后，用来陈述主语的内容或状态的从句。​ 例句：The fact is that he passed the exam.（事实是他通过了考试。）​ 连接词及用法​ that：无实际意义，只起连接作用，不能省略（尤其主语是 fact, truth 等名词时）。​ My idea is that we should start early.（我的想法是我们应该早点出发。）whether：意为 “是否”，不能用 if 代替。​ 例句：The question is whether we can finish it on time. （问题是我们能否按时完成。）​ 连接代词（what, who, which 等）：在从句中作主语、宾语等，有实际意义。​ 例句：This is what I want to say.（这就是我想说的。）​ 连接副词（when, where, why, how 等）：在从句中作状语，表时间、地点、原因、方式等。​ 例句：That's why he was late.（那就是他迟到的原因。）​​ 表语从句必须用陈述语序（主语在前，谓语在后）。​ 当主语是 reason 时，表语从句常用 that 引导，不用 because（即 “The reason is that...”）。​ 即学即练： 根据句意，用适当的连接词填空。​ 1. The news is _______ our team won the game.​ 2. The problem is _______ we can get enough money.​ 3. This is _______ I lost my key yesterday.​ 4. My hope is _______ I can visit Beijing next year.​ 5. The question is _______ will help us with the work.​ 4. It's a great way for me to share my love with others. 这是一种与他人分享爱意的好方法。 it 作形式主语句型​ 当主语是较长的不定式、动名词或从句时，为避免句子头重脚轻，常用 it 作形式主语，而将真正的主语放在句末。​ 常见句型​ It + be + 形容词 + 不定式（to do）​ It is easy to learn English.（学英语很容易。）（真正主语：to learn English）​ It + be + 名词 + 从句​ It is a fact that the earth is round.（地球是圆的，这是事实。）（真正主语：that the earth is round）​ It + 动词（seems, happens 等） + 从句​ 例句：It seems that he is ill.（他好像生病了。）（真正主语：that he is ill） 即学即练： 用 it 作形式主语改写下列句子，保持句意不变。​ 1.
