在英语中,感官动词(如see, hear, smell, taste, feel)、某些动词的被动式(如arrive, come, go, leave, return, start, finish)和情态动词(如can, may, must, should)不能用于完成时态。在使用完成时态时,需要注意动词的特点和含义,避免语法错误。
感官动词
感官动词如see, hear, smell, taste, feel等,表示我们的感觉或者状态,不能用于完成时态。因为这些动词本身就是瞬间动词,表示一瞬间的动作或状态。
例如:
- I have seen the movie. (正确)
- I have been seeing the movie. (错误)
某些动词的被动式
有些动词的被动式不能用于完成时态,例如:arrive, come, go, leave, return, start, finish等。
例如:
- The train has arrived. (正确)
- The train has been arrived. (错误)
情态动词
情态动词如can, may, must, should等不能用于完成时态。因为情态动词本身表示一种情态,而不是动作或状态。
例如:
- He should have finished his homework. (正确)
- He should have been finishing his homework. (错误)
