make sure 的用法和例句

一、基本含义

“make sure”是一个常用的英语短语,其基本含义是“确保”、“确认”或“查明”。它通常用于强调某件事情必须被确切地完成或某个信息必须被准确地核实。

二、结构

  1. 肯定句:make sure + 从句/宾语(名词/代词)+ 动词原形(有时可省略)
  2. 否定句:don't make sure(但更常用的是使用其他否定形式来表达不确定或未证实的状态)
  3. 疑问句:Do you make sure? (较少见,通常用其他方式提问)

注意:“make sure”后接从句时,从句的谓语动词通常用一般现在时表示将来或现在的动作;若表示过去的动作,则用一般过去时。

三、例句

  1. 肯定句

    • Make sure the door is locked before you leave. (离开前请确保门已锁好。)
    • I made sure he understood what I meant. (我确保他明白了我的意思。)
    • They will make sure everything is ready for the party. (他们会确保派对的一切准备就绪。)
  2. 否定句(更多采用其他表达方式)

    • 注意:虽然可以说“Don't make sure...”,但这种说法不常见且可能产生歧义。更常见的否定表达方式是直接使用“not sure”或“I'm not sure...”等。
  3. 疑问句(较少见,通常用其他方式提问)

    • Do you make sure he has received the message? (你确保他已经收到消息了吗?)
    • 但更自然的问法是:Have you made sure he has received the message? 或 Are you sure he has received the message?

      • Make sure of your facts before you accuse anyone. (在指责任何人之前,先确保你的事实准确无误。)
      • Make sure (that) all the lights are turned off when you leave the room. (离开房间时,请确保所有灯都已关闭。)
  5. 与“be sure”的区别

    • “be sure”表示主观上的确信或把握,而“make sure”则强调通过行动来确保某事的实现或验证。例如:
      • I'm sure he will come. (我确信他会来。)
      • Make sure he comes on time. (确保他准时到来。)
