Grammatical homework :

Could is used to ask for a permission:

-Could I open the window?

or to tell I was able to do something in the past:

-When I was young I could touch my nose with my foot.

Would is used to express a condition:

-If I was taller, I would try playing basket-ball.

or to ask something in a way more polite than could.

-Please, I would like to rent a car for holidays.

Should is used to give an advice:

-You should come with us! It will be great fun!

-You should listen to the teacher. Or you won’t be able to do your homework!

Is that good?  I’m not sure.

Dying language in Peru

Hello,
it's a story about four students of antropology and linguistics who work in San Antonio, a Peruvian village, to preserve and revitalize an endangered language named Iquito.
This language is only spoken by twenty six people, so the San Antonio community, deceided that Iquito must be preserved and teached to the youngest.
Students created a dictionary and began teaching classes to twenty adults and thirty five youth.
