As always, I have been making notes about the way my friends and I talk in English. I like to teach you authentic English, which is not necessarily in your school text books. In the class room your teacher may tell you to use “like” to express an assumption. e.g. “The book looks like it has been destroyed in a fire”.
In reality, English speakers would actually say “The book looks as if it has been destroyed in a fire” or “The book looks as though it was destroyed in a fire”.
When to use “as if” and “as though”
We use “as if” and “as though” to express that we think something has happened when we are not 100% sure. If we are 100% positive, then we would say; “The book has been destroyed in a fire. “
Examples of “as if” and “as though”
1. It looks as though it is going to rain tomorrow
For example, if there are clouds in the sky and the temperature is low, we may say that it looks as though it will rain.
2. It looks as if the dog has eaten it!
3. It looks as though we are going to be late for the bus!
Explanation = If the bus leaves the bus stop at 3.30pm and you are still in your house at 3.29pm, it would look as though you would miss the bus. But maybe, if you ran very quickly you would be able to get on in time.
