17. STILL
‘Still’ is used to talk about something that hasn’t
finished – especially when we expected it to
finish earlier.
# I’ve been waiting for over an hour and the bus
still hasn’t come.
# You promised to give me that report yesterday
and you still haven’t finished it.

18. STILL
Still is often used with other tenses as well as
the present perfect. Notice the position of still
before the verb or adjective.
# My grandfather is sixty-nine and he still works
every day at the kiosk he owns.
# Do you still live with your parents?
# Are you still angry with your partner?

19. STILL
If the verb has two parts, still goes between both
the verbs:
# She started her exam an hour ago and she is still
answering the questions.
# When I went to bed, Angelica was still working.
But if one of the two verbs is negative, still goes
before that negative verb:
# Lucy has stopped smoking but her brother still
hasn't quit.
# I took the clock to the repair shop though it still
isn't working.
