Students use the prompts to write sentences
with while, before and after. They will have to
work out which action occurs first or whether
they occur simultaneously in order to decide
which word to use. Ask students to write both
possible answers for those prompts that can take
either a gerund or subject + verb after the
conjunction.
1 While you install/While installing an
operating system, the computer may reboot
several times.
2 Before you deploy/Before deploying major
software upgrades, (you need/have to) train
the users.
3 After you replace/After replacing the hard
drive, everything will go smoothly.
4 After someone forgets a password, (you
need/have to) reset it.
