01这节课练什么

这节课不讲新时态,也不背单词。只做一件事:把长句拆开。

你平时最常卡住的地方,多半不是"单词不认识",而是一句话太长了,不知道从哪儿下手。拆句是手艺,练三次就有手感。

材料是一段真实的英文人物简介,加上一场辩论里的几句硬话。前一半练拆句,后一半练一句特别好用的表达——"当初要是……就不会……"。

你会学到它能帮你干什么
关系代词做从句主语时不能省写邮件、写报告时不漏零件
拆句四步再长的句子也知道先看哪里
the idea that + 一整句话把一整件事装进一个名词里说出口
Had we… , … would not have…复盘时说"当初要是……就不会……"
02一条硬规矩:做主语不能省

先立一条规矩,这节课要反复用到:

关系代词做从句的主语时,不能省。

关系代词就是 who / which / that。它们干两件事:接上前面那个名词,同时在后面的小句子里当一个成分。

看这一句:

Sir Jacob Rees-Mogg is a British Conservative politician who sat in the House of Commons.

后面那截 who sat in the House of Commons,是给 politician 加限定的。这里的 who 就是 sat 的主语——它不能省:

✓ Mogg is a politician who sat in the House of Commons. ✗ Mogg is a politician sat in the House of Commons.

省掉 who,sat 就没有主人了。听的人会以为 sat 是 is 接着往下说,整句就散了。

中文没这个麻烦——中文说"一个当过议员的政客",那个"的"省掉照样通。英语不行:从句缺主语,关系代词必须留。

03长句解剖:一份人物简介

先看原始材料,一段话,四句长句:

Sir Jacob Rees-Mogg is a British Conservative politician who sat in the House of Commons for North East Somerset from 2010 to 2024. He served as Leader of the House of Commons and Lord President of the Council under Boris Johnson, and briefly as Secretary of State for Business, Energy and Industrial Strategy in Liz Truss's government. A leading figure in the campaign to leave the European Union, he lost his seat in the 2024 general election and now presents State of the Nation on GB News. He read history at Trinity College, Oxford, and is the son of William Rees-Mogg, a former editor of The Times.

信息量很大,但骨架只有四块:

句子它说的核心
Sir Jacob Rees-Mogg is a British Conservative politician…他是谁
He served as Leader of the House of Commons…他当过什么
…he lost his seat in the 2024 general election…后来怎么了
He read history at Trinity College, Oxford…他的底子

其余的每一截,都是挂在这四块上的零件。读长句的第一步,是先找到这四块。

04句子 = 动词

第一句拆到最细,是这样四块:

拆出来的块它是什么
Jacob is a politician主干:主语 + 动词 + 表语
who sat in the House of Commons从句,给 politician 加限定
British Conservative形容词,直接贴在人身上
for North East Somerset from 2010 to 2024介词短语,补时间地点

拆句的第一原则只有四个字:

句子 = 动词。

一个句子只有一个核心动词。找到它,句子就站稳了。找到之后左右各看一眼:动词左边是主语,右边是宾语。

上面那句的核心动词是 is,主语是 Jacob。后面 sat 是第二个动词,它住在从句里——所以主句和从句的关系是:

主是老板(主心骨),从是随从。随从发挥自己的职能,但不能抢老板的位置。

顺手把三个介词也收下:

介词管什么例子
of从属——谁属于谁the Leader of the House
for为谁、给谁for North East Somerset
from从哪到哪from 2010 to 2024
05唱歌是一件让我开心的事儿

英语长句和中文长句,是同一个道理。先看一句中文:

唱歌是一件让我开心的事儿。

把它拆成两半:

唱歌 是 事儿主句:X 是 Y
(一件让我开心的)给"事儿"加限定的那半截

翻成英语,骨架一模一样:

Drinking a cup of americano in the morning is something

头疼的是括号里那半截——"让我开心的"。英语不会把它堆在名词前面,而是挂到名词后面去:

something 让 我开心 something makes me happy

两截接起来,中间需要一根钉子,也就是提示词 that:

Drinking a cup of americano in the morning is something that makes me happy.

早上喝一杯美式,是一件让我开心的事儿。

换成你自己的:Reading a page before bed is something that keeps me calm. / Walking into a clean store is something that makes my day.

06that 在从句里干什么

那个 that 到底在做什么?两件事:

作用
1代替左边紧挨着的那个名词(它是个代词)
2在后面的从句里做动作——当主语或者当宾语

回到刚才那句:something that makes me happy。承担动作的是 makes。谁 makes?that。

所以这里的 that 是从句的主语。既然它是主语,就回到开头那条规矩:做主语的关系代词,不能省。

把两句放一起对照,一眼就明白差别:

something makes me happy谁 makes?something 本身
something that makes me happy谁 makes?that(= something)

两句话语法都成立,但意思不一样。第二句多了 the 的味道:"那个让我开心的东西"。that 就是那根把两句话钉在一起的钉子,拔掉,句子就散了。

07拆句四步

长句拆不动,多半是因为不知道先看哪儿。按这个顺序走:

第几步做什么为什么
1找核心动词动词站住了,句子就站住了
2左右各扫一遍,找主语和宾语动词左边是谁,右边是什么
3往后看,找 that / which / in which它们出现的地方,就是从句开始的地方——这类"关系代词"在长句里特别多
4找介词。介词一多,就倒过来看先看介词短语,再回头看主干

拿这句走一遍:

… he lost his seat in the 2024 general election and now presents State of the Nation on GB News.

① 核心动词:lost ② 左右各扫一遍: 左边 he(主语) 右边 his seat(宾语) ③ 往后看: 这句没有 that / which,是一条 and 并列句 ④ 介词:in / on 两个介词短语挂在主干上,表时间地点

一句话说完:他(在 2024 年大选里)丢掉了(议席),现在(在 GB News 上)主持(State of the Nation)。

括号里全是零件,主干就四个词:he lost his seat。

08serve as:以什么身份

简介第二句里有个词要单独拎出来:

He served as Leader of the House of Commons.

serve as + 身份 = 以什么身份任职。这个 as 是"作为",后面跟的是头衔、角色,不是动作。

说法意思
He served as Leader of the House.他担任下议院领袖
My counterpart works as a buyer.我的对接人是个采购
I'm here as the retail channel lead.我是以渠道负责人的身份来的

第三句在自我介绍时特别好用——先亮身份,再讲来意,比 My job is… 利落。

一个小坑:as 还能表示"因为"。怎么分?看后面跟的是什么——跟名词、头衔,就是"作为";跟一整个句子,就是"因为"。

09for 的三副面孔

同一个 for,在不同地方意思完全不同。收进一个框里:

义项例子怎么认
一段时间He sat in the Commons for fourteen years.后面跟一个时间长度
用途a working demo table for the store后面跟东西、跟对象
原因Thanks for coming.后面跟"因为什么"

原文里,for 和 from…to… 撞在了一块:

英文它在说什么
for North East Somerset为哪个选区
from 2010 to 2024从哪年到哪年

两个介词短语各管各的事,中间不加 and,也不加逗号。英语很擅长把好几个介词短语排成一队挂在名词后面——句子就是这么变长的。

10能省的那一半规矩

开头那条规矩还有另一半,同样重要:

关系代词在从句里做什么能不能省
做主语❌ 不能省
做宾语✓ 可以省

看这句:

… Hitler was one of the great evils the world ever saw.

后面那截 the world ever saw,少了点什么?它的完整样子是:

原句the great evils that the world ever saw
从句单独看the world saw evils
that 的身份saw 的宾语——所以它可以不出现

两条规矩其实是同一个原理的两面:

从句缺主语 → who / which / that 必须留;从句缺宾语 → 可以不留。

你自己写的时候,拿不准就都写上——写出来永远不算错。

11the idea that + 一整句话

辩论里有一句,把一整件事装进了名词里:

But the point you've really challenged me on is the idea that being prepared deters war.

骨架是 the point … is the idea …——"你真正质疑我的那一点,是这么个想法"。想法是什么?后面用 that 领一整个句子说出来:

前面的名词the idea
连接词that
后面接的话being prepared deters war(备战能阻止战争)——自带主语和动词,是一句完整的话

这种结构,前面通常就这么几个名词:the idea / the fact / the point / the thought。后面接一句完整的话。

它比"先说结论再解释"好在哪?你能把一整件事当成一个东西来谈论。

结构例子
the fact that …The fact that the stands were held up at customs pushed the launch back.(货架卡在海关这件事,把发布推后了)
the idea that …Let's not run with the idea that one bad store means the whole channel is broken.

注意:这里的 that 不是代词——它不代替谁,也不做成分,它是连接词。所以它不在"能省"的名单里。这类 that,写出来。

12Had we… 倒装虚拟

接下来这句是整节课最值钱的一句。先看原文:

That had we, in 1914, been projecting strength, had the Kaiser thought there was a big British army and the British will take this seriously, he would not have gone through Belgium.

他说的是:"当初要是我们在 1914 年展示了实力,要是德皇认为英国有一支大军队、会认真对待这件事,他就不会穿过比利时了。"

注意这里有两处倒装——本来该出现 if 的地方,if 不见了,助动词跑到了主语前面:

同一句话的两种写法
正常语序If we had been projecting strength,
he would not have gone through Belgium.
倒装之后Had we been projecting strength,
he would not have gone through Belgium.
条件(如果)结果(就不会)
Had + 主语 + 过去分词主语 + would not have + 过去分词

公式记住,句子就能自己造:

  • Had we shipped the stands in September, the launch would not have slipped.
  • Had they read the planogram, the display would not have looked like this.

什么时候用:复盘。它说的是过去已经发生、改不了的事——比 If we had… 更利落,听起来像在讲道理,不像在抱怨。

13could've / should've

辩论里还有两句评价"过去"的话,放一起看:

you could've done it better you should've
说法意思分量
could've done it better你本来能做得更好——说的是你的能力轻
should've done it better你本该做得更好——说的是你的责任重

两个都是对已经过去、改不了的事做评价,所以后面永远跟 have + 过去分词,不能跟动词原形:

✓ You should've told me earlier. ✗ You should told me earlier.

用法提醒:这两个词都带指责味。对同事说之前先掂量一下——could've 是"你行",should've 是"你错"。差一个词,关系差一截。

14would 的委婉

最后讲 would 的另一种本事:把话说进对方耳朵里,不刺人。

Would you please …

Would you please 表面是请求,实际是先假设"你会这么做",再提出来。它给对方留了台阶——对方答应了是顺手,不答应也不算当面驳你。这就是它比 Do it. 好听的原因。

这段辩论里还有一句更妙的,可以直接搬到工作里:

I think this is not really what you want to be doing.

拆开看,它为什么软:

成分作用
I think …先声明"这是我的看法",不是命令
this is not really …用 not really 把否定柔化,不是"你做错了"
what you want to be doing把判断权交回给对方——"这好像不是你想做的事"

同一个意思,三种说法分量差很多:

说法分量
Don't do that.命令
I don't think that's right.直接否定
I think this is not really what you want to be doing.对方自己会改

场景:你走进店里,看到 demo table 上堆满杂物、样板产品全被挡住——

I think this is not really what you want to be doing with the demo table.

没有一句话在骂人,但对方知道该动了。
