从句的分类
1.句子成分分类
2.句子词类分类
从句分三大类 名词 形容词 副词从句
形容词从句(定语从句)
1.形容词从句的思维方式
2.形容词从句的构成
3.形容词从句的限定性和非限定性
The rabbit is eating a carrot
兔子在吃一根胡萝卜
中英思维方式不同
兔子在吃一根(我买来的)胡萝卜
定语
兔子在吃一根我(买来的胡萝卜)
中英思维方式不同
好吃的 我买来的 放在被修饰的名词和代词之前
如胡萝卜
好吃的胡萝卜
我买来的胡萝卜，这个定语甚至会很长
形容词/句子 + 的
虽然单个形容词(或多个形容词，或副词加形容词)作定语也是放在被修饰词之前，如
a tasty carrot
一根好吃的胡萝卜
a [carrot] [[that] I bought]
carrot 先行词 that 关系词
that I bought 定语/形容词从句
这样的包含关系词的从句，也称为关系从句
一根我买来的胡萝卜
被修饰的词之后添加一个和它有关系的词(that)
然后再把这个新词放到另一个句子中
进行补充说明/逻辑阐述
定语=形容词=关系从句
中文:这兔子在吃一根我买来的胡萝卜
英文:这兔子在吃一根胡萝卜([胡萝卜的关系词]我买)
The rabbit is eating a carrot [that I bought] 定语
英语里没有
The rabbit is eating a (I bought的) carrot
中文也没有
兔子在吃一根胡萝卜that我买来
中文:
形式同一定语可能太长
一只[几个月前开始在B站上传视频专门教英语的讨人喜爱的]兔子
英语:
+ 关系词
This is a rabbit [who started uploading videos since a few months ago to focus on English teaching and is liked by many students [who will definitely give this video a thumbs-up]]
甚至可以套娃
西方人的思维偏好
这样的句子太长了，不可取，还是得拆句
关系词 关系代词 关系副词
The rabbit is eating carrot that i brought
兔子正在吃我买的胡萝卜
The teach who ate a carrot is a rabbit
吃胡萝卜的老师是兔子
The teacher whom I saw yesterday is rabbit
我昨天见到的那个老师是一只兔子
The teacher whose favorite food is carrot is a rabbit
最喜欢胡萝卜的老师是一只兔子
The food which teacher likes is a carrot
老师最喜欢的食物是胡萝卜
被描述的事物叫先行词
被提前的是关系代词[that who whom whose which why where when at which for which on which]，然后后面就是描述先行词的
只要是后面描述先行词的都是定语从句
列如
1、这个话题是我感到厌倦的.
This is the topic/theme that I'm tired of.
2、他是那个帮助了我的老师.
He is the teacher who helped me.
3、我们很喜欢那个很幽默的演讲者.

6、这正是我所感兴趣的话题.
That's just the topic that I'm very interested in.
The food that the teacher likes is carrot
which与that可以互换
需要替代的词变为关系代词
在把关系代词提前
that vs which
先行词是唯一的: that
先行词多选一: which
关系副词
限定性和非限定性
The rabbit ate the carrot which was on the table
限定carrot的范围/性质
非限定性
The rabbit ate the carrot, which was on the table.
The rabbit ate the carrot,the carrot was on the table
the carrot两次太啰嗦，接着说
I have a head which is round.
我有好多个头，且其中一个是圆的(还有其他是方的扁的)
I have a head, which is round
我有一个头，这个头是圆的
非限定性有接着补充的特性
My head,which is big,is useful when it rains.
我有大头，下雨不愁
The biggest carrot,which the rabbit ate, was on the table
最大的那根胡萝卜曾在桌上，兔子吃了它
直接去掉which也不影响句意 (which只是补充信息)
The biggest carrot which the rabbit ate was on the table.
最大的那根胡萝卜曾在桌上，兔子吃了它
biggest 已经是唯一最大一个，和which冲突

when 强调突然
while 强调这个时间段内

[If the rabbit sees a carrot], he will eat it
单纯的假设，属于真实条件句
虚拟条件句，和事实相反的假设
If I saw a carrot,I would eat it.
If I had seen a carrot,I would have eaten it
使用了动词虚拟语气的条件副词从句
主将从现
主句用将来时态而从句用现在时态
到底为什么"主将从现"?
一般现在时态
这个时态的重点往往不是"现在"这个时间,而是"一般"这个状态
一般 简单的默认的普通的状态
Rabbit eat carrots
The sun rises in the east
习惯/客观事实 不等于 现在
和现在没有啥关系
我不确定一定看到胡萝卜，所以条件句只能去掉将来will，表达一般 默认 普通的状态
如果这个假设的条件成立，那我一定会明确的做吃胡萝卜这个动作
中文
如果我将会看见一根胡萝卜，我会吃它
如果我看见一根胡萝卜，我会吃它
条件句总是比主句落后一个时间段
这也可以应用于虚拟语气
虚拟语气的saw不是表达时间，不是说我明确在过去看见...
而是表达与现实相反的条件
unless
也可以引导条件副词从句，就是把if反着说
[If you like this video],you will give it a thumbs-up
如果你喜欢这个视频，你会给它点赞
[If you don't like this video],you will not give it a thumbs-up
如果你不喜欢这个视频，你不会给它点赞
[Unless you like this video,you will not give it a thumbs-up]
除非你喜欢这个视频，不然你不会给它点赞
其他引导词
provided，as long as，in case
让步副词从句
即使/就算...也.
Even if I see a carrot,i will not eat it.
这个but是连词，咱们这个是从句，复杂句，你加个连词那不是复合句了吗
这个句子就分不清是复杂句还是复合句
no matter 不管如何
no matter 可以用 regardless of取代
Regardless of what kind of video I make, you will give it a thumbs-up
不管我做什么样的视频，你都会给我点赞

原因副词从句，目的副词从句，结果副词从句
A 导致 B
The rabbit ate the carrot because he was hungry
because he was hungry 原因副词从句
Because the rabbit was hungry, so he ate the carrot

because引导从句，所以从句前什么也不用加，构成了一个复杂句
so是用来构成一个复合句的连词

既然你饿了，你可以吃这胡萝卜
since介绍某个原因
不是时间时间副词从句那个，从某个时间点开始的意思
as

因为你之前不在这儿，所以吃胡萝卜没带你一个
这里的as和方方式语从句中的 Eat the carrot as i do中的那个 "像..一样"有区别
这里也是表原因
because > since > as
because有实实在在的因果关系
since是总所周知
as显而易见的事实
[You must really like me], for [you have given all my videos a thumbs-up.]
推测 推测的原因
你肯定很喜欢我英语兔，因为你给我所有视频都点赞啦
推测的结果你喜欢我，推测的原因，你给所有视频都点赞了
for构成复合句
[Because you like me], [you have given all my videos a thumbs-up]
原因 结果

之所以做[主句]是因为要达到目的[从句]
In order that I could finish the video in time, I pulled an all-nighter
为了及时完成视频，我熬夜不睡(肝视频)
基本等于
I pulled an all-nighter so that I could finish the video in time
结果副词从句

The temperature was low so that the lake froze
气温很低，所以湖结冰
用结果来解释，不能是目的就是让湖结冰

so that引导副词从句，解释说明主句的情况，是主句动作产生的结果
