A lesson on computing / TOEIC
This is a photo taken in a room where there are a lot of personal computers.
It might be a computer room of a library.
The place is not crowed, and only one computer is now on use by one adult woman and two children.
The title of the picture is "a lesson on computing", but I doubt about that.
Under ordinary circumstances, the woman should be a teacher, and the two children are students.
Yet, the two children are not looking at the computer screen or keyboard, but they are looking at the woman's face. And the woman uses only one finger to touch a key, and her finger position is nothing to do with "blind tough".
She doesn't seem to be an expert, but rather a beginner.
They seems happy and enjoy themselves.
Taking them into consideration, I might think that the student is the woman, and the two children are her tutors. Though it seems unlikely.
In conclusion, I don't think it is a lesson. The all three are enjoying to play with the computer, maybe they're playing a game.
If I stick to "a lesson", I think there is no tutors. The all three people are participants of the self-lesson program of the computer, which are named, for example, "A happy and easy lesson---You can do it by yourself" or something.
