✨ 英语基础语法知识 🌟
🌈 一、为什么学习语法？ 🎓
- 语法 VS 词汇
- 词汇是语言的砖块，语法是搭建房屋的规则。
- 词汇让你表达单个意思，语法帮你串联成完整句子。
- 例子：知道“apple”和“eat”，但没有语法，你无法说出“I eat an apple.”
- 学习语法的意义：
- 提高语言准确性，避免歧义。
- 为考试（如同等学力英语）打基础，应对阅读、写作等题型。
- 怎么学习语法？
- 考什么学什么：针对考试题型（如从句、代词）重点突破。
- 结合真题实践，理解语法在语境中的应用。
- 制定计划，每天攻克一个知识点，积累记忆口诀。
🍀 二、词法：代词 ✏️
🌟 （一）指示代词：表格速览 📍
| 代词 | 用法 | 例子 | 备注 |
|---|---|---|---|
| this/these | 指较近的人或物 | This is my book. | 近（物理或心理距离） |
| that/those | 指较远的人或物 | That is your bag. | 远（物理或心理距离） |
| this/that | 代替前文短语/句子 | It’s raining, and this keeps us indoors. | 避免重复，如that of Korea |
| which | 代替句子（定语从句中） | It was raining, which kept us indoors. | 非正式可用which |
记忆口诀：
“this近来that远，代替重复莫怠慢。”
🌸 （二）It 的用法：表格速览 🐾
| 用法 | 说明 | 例子 |
|---|---|---|
| 代替前文名词 | 指代前面提到的东西 | He took a stone and threw it. |
| 代替短语/从句 | 代替前面提到的事情 | He won’t find it easy. (it = 赢得奖学金) |
| 指时间/天气/距离 | 表示自然现象或抽象概念 | It is fine today. / It is 5 miles. |
| 代替中性名词 | 如baby/child或动物 | The child lost its way. |
| 形式主语 | 代替真正主语（to do等） | It’s important to learn English. |
| 形式宾语 | 代替真正宾语（动名词等） | I find it exciting working here. |
| 强调句 | It is/was + 强调部分 + that/who | It is English that is important. |
记忆口诀：
“it多才又多艺，时间天气形式替；强调句子加that，重点突出别忘记。”

- 关系词：
- 代词：who/whom/whose/which/that
- 副词：when/where/why（=介词+which）
- He came at a time when we needed help.（when = at which）

- 前置：He who has never tasted bitter does not know sweet.（未尝苦者不知甜）
- 后置：I told the story to John, who told it to his brother.（约翰又告诉了他弟弟）
记忆口诀：
“定从修饰紧相连，关系词分代与副。”

调整说明
- “指示代词” 和 “It的用法” 已整理成表格，列出用法、例子和备注，简洁易懂。
- “句子成分” 和 “基本句子结构” 也用表格呈现，突出核心内容，方便对照学习。
- 从句部分保持原文结构，因为它们需要更多解释，表格可能不够直观。
