| It’s vital that ... should ... | ……是至关重要的 |
| It’s necessary that ... should ... | ……是必要的 |
| It’s essential that ... should ... | ……是必不可少的 |
例如：

你理解这一点很重要。
B. should 可以省略：Subjunctive
在 A 部分的句型中：
should 可以省略
这时后面的动词使用：
动词原形
这种形式叫：
the subjunctive（虚拟语气 / 假设式）
4. should 省略后的结构
例如：
It’s essential that everyone should be here on time.
可以变成：
It’s essential that everyone be here on time.
注意：
be
不是：
is / are
5. insist
I insisted that he should apologise.
可以说：
I insisted that he apologise.
这里：
apologise
保持动词原形。
6. suggest
What do you suggest we should do?
可以说：
What do you suggest we do?
7. demand
Many people are demanding that something should be done about the problem.
可以说：
Many people are demanding that something be done about the problem.
8. Subjunctive 的核心结构
that + 主语 + 动词原形
例如：
| 普通 should 结构 | Subjunctive |
|---|---|
| everyone should be | everyone be |
| he should apologise | he apologise |
| we should do | we do |
| something should be done | something be done |
注意：
即使主语是 he / she / it，动词也不加 -s。
例如：
I suggest that he go.
不是：
❌ I suggest that he goes.
9. Subjunctive = infinitive without to
图片中的定义：
This form (be / do / apologise etc.) is called the subjunctive.
它的形式和：
infinitive without to
相同。
也就是：
动词原形，不带 to。
例如：
- be
- do
- go
- apologise
- eat
- work
10. 也可以使用普通现在时或过去时
图片中还说明：
You can also use normal present and past forms.
例如：
It’s essential that everyone is here on time.
也可以。
以及：
I insisted that he apologised.
也可以。
所以有时你会看到三种形式：
| 形式 | Example |
|---|---|
| should | I insisted that he should apologise. |
| subjunctive | I insisted that he apologise. |
| normal form | I insisted that he apologised. |
C. suggest 的特殊规则
11. suggest 后面不能用 somebody + to do
这是这一页非常重要的规则。
不能说：
❌ suggest somebody to do something
例如：
❌ What do you suggest us to do?
是不正确的。
12. suggest 的正确结构 1
suggest + that + 主语 + should + 动词原形
例如：
What do you suggest we should do?
你建议我们应该做什么？
13. suggest 的正确结构 2
也可以省略 should：
suggest + that + 主语 + 动词原形
例如：
What do you suggest we do?
14. Example — Jane won the lottery
Jane won the lottery.
Jane 彩票中奖了。
你可以说：
I suggested that she should buy a car with the money she won.
我建议她用中奖的钱买辆车。
也可以说：
I suggested that she buy a car.
或者：
I suggested that she bought a car.
但是不能说：
❌ I suggested her to buy a car.
15. suggest 的结构总结
| 正确结构 | Example |
|---|---|
| suggest + that + should | I suggest that she should go. |
| suggest + that + subjunctive | I suggest that she go. |
| suggest + normal form | I suggested that she went. |
| suggest + V-ing | I suggest going. |
错误：
❌ suggest somebody to do
16. suggest + V-ing
还可以使用：
suggest + V-ing
例如：
What do you suggest doing?
你建议做什么？
I suggest waiting until tomorrow.
我建议等到明天。
17. suggest 四种常见形式
| 结构 | Example |
|---|---|
| suggest that ... should do | I suggest that we should leave. |
| suggest that ... do | I suggest that we leave. |
| suggest + V-ing | I suggest leaving. |
| ❌ suggest somebody to do | ❌ I suggest you to leave. |
D. should 用在某些形容词后
18. 常见形容词
should 还可以出现在以下形容词后：
- strange
- odd
- funny
- typical
- natural
- interesting
- surprised
- surprising
这时候 should 通常不是：
“应该做”
而是表示：
说话者对某件事感到奇怪、意外、自然等。
19. Example — It’s strange that...
It’s strange that he should be late.
他居然迟到了，这很奇怪。
后面补充：
He’s usually on time.
他平时通常都很准时。
这里：
should be late
不是：
“他应该迟到”
而是：
“居然会迟到 / 竟然迟到了”
20. should 的这种语气
可以理解成：
“竟然 / 居然会……”
例如：
It’s strange that he should say that.
他居然会那么说，真奇怪。
It’s surprising that she should know so much.
她居然知道这么多，真令人惊讶。
21. Example — surprised
I was surprised that he should say such a thing.
我很惊讶他居然会说这种话。
这里的：
should say
不是建议。
而是：
对已经发生的行为表示惊讶。
22. should 在形容词后的中文感觉
| English | 自然中文 |
|---|---|
| It’s strange that he should... | 他居然……，真奇怪 |
| It’s surprising that... | ……居然如此，很令人惊讶 |
| It’s natural that... | ……这样也很自然 |
| It’s odd that... | ……居然这样，有点奇怪 |
23. Unit 33 和 Unit 34 的 should 不完全一样
Unit 33 主要是：
should = 应该 / 建议 / 按理说
例如：
You should go to bed.
你应该睡觉。
Unit 34 进一步出现：
语法结构中的 should
例如：
I suggest that he should go.
It’s essential that he should be here.
以及：
It’s strange that he should be late.
所以 should 不一定每次都直接翻译成：
“应该”。
24. 四种 should 的核心感觉
| 类型 | Example | 核心感觉 |
|---|---|---|
| 建议 | You should go. | 应该 |
| 预期 | He should arrive soon. | 按理说 |
| insist/suggest 等结构 | I suggest that he should go. | 建议 / 要求 |
| strange/surprising 后 | It’s strange that he should go. | 居然 / 竟然 |
25. insist / demand / recommend / suggest / propose 的共同点
这些动词都有一个共同特点：
不是单纯陈述事实，而是在表达要求、建议、主张。
例如：
I insist that he should apologise.
不是说：
他已经道歉了。
而是：
我要求他去道歉。
所以后面的行为：
不是事实陈述，而是“希望 / 要求发生的行为”。
26. 为什么会出现 subjunctive？
例如：
I suggest that he go.
这里：
go
不是一般现在时。
因为：
一般现在时第三人称应该是 goes。
这里保留：
go
就是因为它不是在描述：
“他平时去”。
而是在表达：
“我建议他去。”
所以使用：
subjunctive。
27. 普通事实 vs Subjunctive
对比：
普通事实
He goes to work at eight.
他每天 8 点去上班。
这里：
goes = Present Simple
建议 / 要求
I suggest that he go at eight.
我建议他 8 点去。
这里：
go = Subjunctive
28. he goes vs he go
| 形式 | Example | 含义 |
|---|---|---|
| he goes | I know he goes there. | 陈述事实 |
| he go | I suggest that he go there. | 建议 / 要求 |
这是 Subjunctive 最明显的特征之一。
29. be 更容易看出区别
普通形式
He is here.
他在这里。
should
It’s essential that he should be here.
他必须在这里。
Subjunctive
It’s essential that he be here.
这里使用：
be
而不是：
is
这是最明显的虚拟语气形式。
30. should / subjunctive 对照
| should 结构 | Subjunctive |
|---|---|
| he should be | he be |
| he should go | he go |
| she should eat | she eat |
| something should be done | something be done |
| we should leave | we leave |

32. 最重要的结构表
| 场景 | 结构 |
|---|---|
| insist | insist that + subject + should do |
| demand | demand that + subject + should do |
| recommend | recommend that + subject + should do |
| suggest | suggest that + subject + should do |
| propose | propose that + subject + should do |
| important / essential 等 | adjective + that + subject + should do |
33. Subjunctive 版本
上面的 should 都可以变成：
that + subject + 动词原形
例如：
| should | subjunctive |
|---|---|
| I suggest that he should go. | I suggest that he go. |
| It’s essential that she should be here. | It’s essential that she be here. |
| They demanded that something should be done. | They demanded that something be done. |
34. suggest 最容易犯的错误
不要说：
❌ I suggest you to go.
可以说：
✅ I suggest that you go.
✅ I suggest that you should go.
✅ I suggest going.
所以记住：
suggest 后面不使用 object + to do。
35. 一个很实用的判断方法
看到：
- suggest
- recommend
- insist
- demand
- propose
先想到：
“这不是在陈述事实，而是在提出一个希望发生的动作。”
因此后面很自然会出现：
should + 动词原形
或者：
subjunctive 动词原形
36. strange + should 的思维
看到：
strange / surprising / odd
后面的 should 不要翻译成：
“应该”
而应该理解：
“居然会……”
例如：
It’s strange that he should leave so early.
自然中文：
他居然这么早就走了，真奇怪。

| I suggest that you should go. | 我建议你去 |
| I suggest that you go. | 我建议你去 |

一句话记忆
insist / demand / recommend / suggest / propose
后面可以：
that + subject + should + 动词原形
也可以：
that + subject + 动词原形
例如：
I suggest that he should go.
I suggest that he go.
important / vital / necessary / essential
同样可以：
It’s essential that he should be here.
或：
It’s essential that he be here.
suggest
特别记：
❌ suggest somebody to do
正确：
suggest that somebody do
suggest that somebody should do
suggest doing
strange / surprising + should
这里的 should 不要理解成“应该”，而是：
“居然 / 竟然会……”
最核心：
SHOULD 可以是“建议”，也可以只是一个语法结构中的标记。
