第一部分：宾语从句—— 三大考点定乾坤
考点一：引导词（连接词）三选一
从句类型 | 引导词 | 例句 |
陈述句变从句 | that（可省略） | I know (that) he is right. |
一般疑问句变从句 | if / whether | I don't know if/whetherhe will come. |
特殊疑问句变从句 | 原疑问词（what, who, when, where, why, how 等） | Can you tell me wherehe lives? |
绝大多数情况两者通用 但与 or not 连用、在介词后、在不定式前只能用 whether
考点二：语序—— 永远是陈述句语序！
2024 年多地中考真题中反复出现此类陷阱：Do you know _____? 四个选项中一定有三个是疑问语序，只有一个是陈述语序。
考点三：时态呼应
主句时态 | 从句时态 |
主句现在时 | 从句按需要任意时态 |
主句过去时 | 从句必须用相应的过去时态（客观真理除外） |
He said he would come the next day.（主句过去时，从句用过去将来时） The teacher told us the earth goes around the sun.（客观真理，始终用一般现在时！）
第二部分：定语从句—— 关系代词的选词填空
一、关系代词速查表
关系代词 | 先行词 | 在从句中充当 |
who | 人 | 主语/宾语 |
whom | 人 | 宾语（正式） |
which | 物 | 主语/宾语 |
that | 人/物 | 主语/宾语 |
whose | 人/物 | 定语（……的） |
二、只用 that 不用 which 的四大情况
先行词被最高级修饰：This is the best film that I have ever seen. 先行词被序数词修饰：The first thing that we should do is to make a plan. 先行词是不定代词（all, everything, nothing, something, anything, little, much 等）：Is there anything that I can do for you? 先行词被the only, the very, the last修饰：He is the only person that understands me.
三、关系代词可以省略的情况
The man (who/that) I met yesterday is my teacher. This is the book (which/that) I bought last week.
第三部分：状语从句—— 九大类型，核心掌握四种
1. 时间状语从句
连词 | 用法 | 例句 |
when | 当……时（时间点/段） | He was reading whenI came in. |
while | 当……时（时间段，常接进行时） | WhileI was cooking, he was watching TV. |
before/after | 在……之前/之后 | Think carefully beforeyou answer. |
until/till | 直到…… | I waited untilhe came back. |
as soon as | 一……就…… | I'll call you as soon asI arrive. |
since | 自从……以来 | Sincehe left, I've been lonely. |
2. 条件状语从句（if / unless）
If it rains tomorrow, I will stay home.（不是 will come！） Unless you hurry up, you will miss the bus.（unless = if...not）
3. 原因状语从句（because / since / as）
连词 | 语气强弱 | 用法 |
because | 最强 | 回答 why 提问；强调未知原因 |
since | 中等 | 已知原因，“既然” |
as | 较弱 | 明显原因，“由于” |
4. 让步状语从句（although / though / even though）
✅ Although he is old, he is very active. ❌ Although he is old, but he is very active.

✅ 答案与解析
1. B— 宾语从句必须用陈述句语序（主语在前），Could you... 是委婉语气，从句用一般现在时。 2. C— 先行词 the day 在从句中作时间状语，用关系副词 when。 3. C— if 条件状语从句用一般现在时表将来（rains），主句用一般将来时（will stay）。 4. A— 先行词 the man 指人，在从句中作主语，用 who。 5. B— 与 or not 连用只能用 whether，不能用 if。
