语法错误记录 ​

只记录真实训练中犯过的语法错误。不系统整理完整语法知识。

过去时态 ​

find 的过去式 ​

  • ✗ He finally founded the address.
  • ✓ He finally found the address.

found 是 find 的过去式，意思是"找到"。founded 是 found 的过去式，意思是"创立、建立"。

复述时时态混用 ​

在复述一段过去的故事时，容易不自觉地切换回现在时：

  • ✗ Harry doesn't know how to get there.

  • ✓ Harry didn't know how to get there.

  • ✗ They go to the restaurant.

  • ✓ They went to the restaurant.

提醒：复述开始前先确认时态基调。如果是在说过去发生的事，全程保持过去时。

冠词 ​

可数名词单数需要冠词 ​

  • ✗ He met old woman.

  • ✓ He met an old woman.

  • ✗ They went to restaurant.

  • ✓ They went to the restaurant.

a 和 an 的选择 ​

元音音素前用 an：

  • an old woman
  • an hour
  • an interesting story

ask 的句型 ​

ask someone how to... ​

  • ✗ He asked the woman for how to get to the street.
  • ✓ He asked the woman how to get to the street.

ask someone how to do something 中间不需要 for。

ask someone for something 用于请求具体的东西：

  • He asked her for help.
  • He asked her for directions.
