英语中的情态词包括 can, could, may, might, shall, should, will, would, must。这些情态词有一个共同点，那就是它们后面跟的动词形式。但是问题是，情态词后面应该接原形还是什么？
首先，我们来看一下情态词后面接原形的情况。当情态词后面跟的动词表示一个动作或状态时，我们就需要使用动词的原形。例如：
- I can swim.
- He must study harder.
- She will play tennis tomorrow.
但是当情态词后面跟的动词表示一个完成的动作或状态时，我们就需要使用动词的完成时态，也就是 have+动词的过去分词形式。例如：
- They could have won the game if they had played better.
- She should have studied more for the exam.
- He might have been promoted if he had worked harder.
此外，当情态词后面跟的动词表示一种虚拟的状态或情况时，我们就需要使用动词的虚拟语气形式。例如：
- If I had more time, I could visit my family.
- If he were taller, he could be a basketball player.
- She would be happier if she had more friends.
综上所述，情态词后面接原形还是什么，取决于动词的时态和语气。我们需要根据具体的语境来做出正确的选择。希望这篇文章能够帮助你更好地理解情态词的用法和注意事项。
