Both as if and as though introduce how something seems or a comparison.

The idea

For a plausible appearance, use the tense that fits the time, as in it is raining or it has rained. For an unreal present comparison, a past form such as were or was shows distance from reality; were is more formal. An unreal earlier situation can take a past perfect.

Examples

  • The sky looks as if it is going to rain.
  • Maya sounds as though she has caught a cold.
  • The child talks as if he were a famous explorer.
  • I feel as though I were floating above the water.
  • The room smells as if someone has baked bread.
  • Leo waved as though he had known us for years.

Watch out

Do not assume a past form always refers to past time: as if she were can describe an imaginary situation now.
