Learn English – What’s the difference between “ask” and “be asked”

1. I've worked here since two years ago

And

2. I've been working here since two years ago.

The obvious difference between these sentences is the first sentence uses present perfect simple and the second sentence uses present perfect continuous. In many contexts, these tenses are interchangeable. However, we use present perfect continuous to emphasise the continuity of the action or event. Let's take a look at the sentences above, in the first sentence: The continuity of the event is not important. In the second sentence: You emphasise the lenght of time you're working there.

Another important thing about the usage of present perfect continuous and present perfect simple is, present perfect simple is typically used for stative verbs. For instance,

I've known him for six years.

It would sound weird if you say

I've been knowing him for six years.

To conclude, there is no quite difference between these two tenses. But the usage depends on the suitability in a context.

Ditto Joe. Let me add:

To "enlighten" is to give information or wisdom. To "inspire" is to motivate.

"Enlighten" is rarely used today. But an example of a correct usage is, "I didn't know about the new rules until my boss enlightened me."

Perhaps somewhat more common is the adjective "enlightened", meaning "wise" or "compassionate". Like, "Tsar Alexander considered himself an enlightened monarch."

An example sentence with "inspire" is, "I was inspired to buy a new car by the desire to impress my girlfriend."

They're not really the same thing at all. I could get new information and do absolutely nothing about it, I might just say, "yeah, whatever". I could be inspired without getting any new information. Perhaps someone just encouraged me.

Where they might somewhat overlap is that "inspire" can be used to mean that one idea led to another. Like, "Mr Smith's latest novel was inspired by a story he read in the news." He got some idea or information, and that idea led to another idea.

But I can't think of any sentence where you could substitute "inspire" for "enlighten" or vice versa without significantly changing the meaning.
