Many thanks,
Gave it a look, got a Grammar and i think I got it, can someone take a look, and advice me about my choices?
Thanks
There (be)
has been ( present perfect?)drought here for the past 15 years; for the past four years it (be)
has been (perfect?) increasingly severe and this year the area (have)
had (Past) only half as much rain as in the previous year. The sands (move)
moved (past?) south.
Now the desert (sweep)
sweeps (present because its an action that still hapens) around the town and (surround)
surrounds/surrouding (present?) it entirely.
Occasionally it is possible to glimpse beneath the dust the baked clay surface of what was once a fertile loam, but that is rare.
Huge dunes of sand (creep)
is creeping (Present Pcontinuos) onwards, thousands of tons at the rate of 20 miles a year.
