Grammar -- Present Perfect and Gerunds

Present Perfect

In the English language verbs have different forms depending on their use.
One of these is the Present Perfect. This form is used in cases, where you ask or talk about an action that has been completed - or an action that started in the past and is still in progress. (It is used in stating a fact).
It is formed like this:

Subject + have/has + past participle

For example:
I've been to London.
I've just started a new job.
I've just arrived.

The interrogative form is formed like this:

Have/has + subject + past participle

Have you been to Beijing?
Have you studied English?
Have you finished working?

Gerunds

Verbs can be turned into nouns by adding the ending '-ing'. This type of noun is called 'a gerund'. After certain verbs we usually use a gerund. For example:

To finish - have you finished working?
To hate - I hate studying!

Here, the words 'working' and 'studying' are gerunds.
