Question

Nota: Para formar el tiempo presente simple perfecto, has o have se usa con un participio pasado para describir una acción que ha sucedido en el pasado y que aún puede estar sucediendo. El participio pasado es a menudo regular y, por lo tanto, conserva su ortografía en tiempo pasado simple, como lo hace "visitado" aquí.

Example: I / You / We / they (visit) have visited Argentina before. Example: He / She / It (visit) has visited Argentina before.

1) I (visit) ___Australia before.
2) You (work) ___in Mexico .
3) We (be) _____in Canada for two years .
4) They (live) ___in China since 2015.
