observe the tablet and answer the questions. (present perfect continuos ) a) he (worke) um This company since 1995. b) I (wait) for you since te o o'clock. c) Mary ( live/not) in Germany since 1992. d)He ( play) tennis for Five hours. e) How long ( learn /gou) english?

Answer 1

A fórmula para o present perfect continuous, que indica uma ação que está em pleno andamento no presente, começou no passado e que provavelmente continuará por algum tempo no futuro, é:

to have + been + verbo principal no gerúndio (ing)

Sendo assim, as questões propostas ficariam:
a)He has been working in this company since 1995.
b)I have been waiting for you since ten o'clock.
c)Mary has not been living in Germany since 1992.
d)He has been playing tennis for five hours.
e) How long have you been learning English?

Note que o verbo to have, como verbo auxiliar, sofre a mudança, típica do presente, de "have" para "has" nas pessoas de he, she e it. Além disso, nas frases negativas, o NOT vem logo após o verbo auxiliar ou junto a ele nas formas contratas haven't e hasn't.
