 Re: there is VS. has
Be careful - it is rained is not correct. In the example
A : What's the weather like where you are?
B : Well, it's rained today, but it's fine now.
it's rained = it has rained.
"it" here doesn't mean anything. Expressions like : It's raining... It seems ... It's important that ... are called "empty it" constructions. It is empty of meaning and just serves as a grammatical subject. In English verbs must have a subject (grammatically) and so when there really isn't one (in terms of meaning) "it" is used. |
