情态动词
高中语法之情态动词情态动词本身有词义，表示说话人的某种语气或感情，主要用以表明说话者对某一行为的态度和观点，主要包括揣测、判断、需要、可能等意思。
但词义不完整，不能单独作谓语，只能和动词原形一起构成谓语。

例外的仅有have to动词原形跟后面，说话语气较委婉。
can表能力，may许可，must责任或义务。
否定回答needn’t换，需要need,dare敢。
should应该，would愿，have to被迫表客观。
情态动词的用法：一、can/colud1.表示能力；can能够，can’t不能够，表示有能力做，知道如何做或能够发生.could 表示过去的能力。
He can speak Spanish, but he can’t speak Russian.can 与be able to的区别1)can 只用于一般现在时与一般过去时两种时态中，be able to则可用于更多的时态。

can’t的过去式
在英语中，can't 是一个很常见的单词，它表示“不能、不会”。
而 can't 的过去式则是 couldn't，意思是“不能、不会（过去时）”。
那么，在什么情况下我们会用到 couldn't 呢？下面，我将从不同的角度为大家解释。
1. 语法角度
在语法上，couldn't 是 can 的过去式，表示过去某个时间点或某个时间段内，某件事情无法完成或无法做到。
比如：
- 当我尝试打开电脑时，它不能够启动。
When I tried to turn on my computer, it couldn't start up.
- 昨天我们没有成功地联系上他。
We couldn't get in touch with him yesterday.
2. 情感角度
可以说，can't 和 couldn't 这两个单词，都是表达情感时常用的词汇。
在情感上，couldn't 通常用来表示某个人或某个团体在某
个时刻或某个时间段内，无法做到某个事情，或者遇到了困难。
比如： - 我们的团队在这个项目上遇到了很多挑战，但我们一直在努力，直到最后我们成功地完成了它。
Our team faced a lot of challenges on this project, but we kept working hard and in the end, we couldn't have done it without each other.
- 在我的职业生涯中，我遇到了很多困难，但我一直在努力，直到我最终实现了我的梦想。
In my career, I faced a lot of
challenges, but I kept working hard and in the end, I couldn't be happier with where I am now.
3. 文化角度
在英语语境中，can't 和 couldn't 这两个单词，还有一些文化内涵。
比如，在英国文化中，can't 和 couldn't 经常用来表达某种礼貌。
比如：
- 如果你被邀请参加一个晚宴，但你不能参加，你可以说：I'm afraid I can't make it.（恐怕我不能来。
）
- 如果你想向某个人道歉，但你不确定他或她是否愿意接受你的道歉，你可以说：I couldn't be more sorry.（我再也不能更抱歉了。
）
4. 实用角度
最后，我们来看看 couldn't 在实际生活中的用法。
比如，在旅游中，如果你想问路，但你不会说当地语言，你可以这样说：
- Excuse me, do you speak English? I couldn't find my way to the train station.（打扰一下，你会说英语吗？我找不到去火车站的路。
）
总之，can't 和 couldn't 是英语中非常常用的单词，它们不仅仅代表着某种语法规则，还有着丰富的情感和文化内涵。
我们需要注意，不同的语境和场合下，can't 和 couldn't 的用法也会有所不同。
