英语中,介词后面加-ing形式是一个常见且正确的语法结构,如"I'm interested in learning English"。但并非所有介词都可以后面加-ing形式,有些只能接名词或代词,例如"He's waiting for his friend"。因此,需要根据具体的语境来判断介词后面的用法是否正确。
首先需要明确的是,介词后面加-ing形式是完全正确的语法结构,而且也是非常常见的用法。例如,在下列的句子中,介词后面都加了-ing形式:
- I'm interested in learning English.
- She's good at playing the piano.
- He's afraid of flying.
在这些句子中,介词后面的-ing形式都是表示一个动作或状态的进行中。也就是说,这些句子中介词后面的-ing形式都是作为介词的宾语,用来进一步描述介词所表示的意思。
但是需要注意的是,不是所有的介词都可以后面加-ing形式。有些介词只能后面接名词或代词,而不能加-ing形式。例如,以下的句子是错误的:
- He's waiting for meeting his friend. (应该是waiting for his friend.)
- She's thinking about leaving her job. (应该是thinking about her job.)
- They're talking about going to the beach. (应该是talking about the beach.)
