常见错误

• ✗Social media have changed society.
  ✓Social media has changed society.

  social media 在现代英语里当单数用，所以配 has，不配 have。

• ✗I use Instagram since 2018.
  ✓I have used Instagram since 2018.

  跟 since 连用要用现在完成时，不能用一般现在时。

• ✗She is addicted to social media since years.
  ✓She has been addicted to social media for years.

  years 是一段时长，要用 for；这里用现在完成进行时更自然。

• ✗Privacy became a big problem recently.
  ✓Privacy has become a big problem recently.

  跟 recently、lately、already 这类副词连用，英式英语习惯用现在完成时。

• ✗I have 500 followers in Instagram
  ✓I have 500 followers on Instagram

  说网络平台上的东西，介词用 on，不用 in。

• ✗The social medias are dangerous
  ✓Social media is dangerous

  social media 在英语里不可数，没有 medias 这个复数。
