Dear teachers,
Could you possibly correct these sentences if anything is not correct?:

In these past three years / In these three years, there appeared many shops selling garments on this banned street.

We have had a lot of problems in these past three weeks/in these three weeks
We have been having a lot of problems in these past three weeks/in these three weeks

Thank you in advance

I would prefer to use the prepositions "over" or "during". Also, don't combine "these" with "past three". "These" refers to some time period mentioned earlier. For example:

The years between 1990 and 1993 were quite revolutionary. In (or during / over) these three years,....

The first weeks in February were especially difficult. During these three weeks, we had a lot of problems.

Hi,
What's a 'banned street'?

Perhaps you mean 'a street on which such shops are banned'.

Thank you AlpheccaStars and Clive very much.
Yes, I mean the street that is banned.Is it natural to say so?Could you give me another expression that sounds more natural to native speakers' ears?

Thank you Clive, but Have you got any way to say in the form of a noun phrase like " forbiden area..."?
Hi,
Sure.

XYZ Street is a forbidden area. (as you suggest)

No-one is allowed to go to XYZ Street.

No-one is allowed on XYZ Street.
