Hi Priscila,

The usual preposition after aware and unaware is of. The preposition about is of a much more general nature as in knowing about something.

Dear Teachers,
For Q7, I don't understand why you used which for the employees instead of who?
Many thanks

Dear Guest
As you can see, it was the mistake which testtakers are supposed to correct

Hi,
I would like to ask you about the words "recently" and "lately". As far as I know they have the same meaning and are used in Present Perfect. But can we use the word "lately" or "recently" in Past Simple and in what cases?
Thanks

Hi Iraberezhany,

Both 'recently and 'lately' are associated with the past not long ago. Both 'recently' and 'lately' can refer to a period of time but whereas 'recently can also refer to a point of time, 'lately' tends to refer only to a period of time. Look at these two sentences:

Recently/lately I have been reading several biographies. Recently I read an excellent biography of Shakespeare.

So, Alan, as far as I understood 'recently' can be used in Present Perfect and Past Simple and 'lately' only in Present Perfect.
Are these sentenses correct?
1) RecentlyLately I have recieved many letters from my friend.
2) RecentlyLately my son have been eating too much meat.
3) Recently I saw an interesting true-to-life film. (not lately)
Can we use both 'recently' and 'lately' in the first sentence? Or only recently?
