As If / As Though + Past Subjunctive

One of the uses of the past subjunctive as if/as though is to indicate unreality, improbability or doubt in the present. Both forms can be used interchangeably,
although as if is more common.

Examples:

  • He behaves as if she was the boss here. (But she isn't the boss or we don't know whether she is the boss or not.)
  • He talks as though he knew who Jane was. (But he doesn't know or we don't know whether he knows or not.)
  • He looks at me as if I were guilty. (But I am not guilty.)

The verb preceding as if/though can be put to a past tense without changing the tense of the subjunctive:

  • He talks/talked as though he knew who Jane was.

 After as if/though we use the Past Perfect when referring to a real or imaginary action in the past:

  • He talks about Rome as though he had been there himself. (But he hasn't or probably hasn't or we don't know whether he has or not.)

Again, the verb preceding as if/though can be put into a past tense without changing the tense of the subjunctive:

  • Her eyes look/looked as if she had been crying.
