Theory:
Common expressions are widely tested in sentence completion exercises becuae they nearly always use structural words. Examples of these are:
in fact,
instead of, part of,
made aware of
due to,
the first to
by definition,
go by bus,
around the world,
named after,
not only but also,
more likely than not,
for good measure,
fall out with,
cover up,
no matter what
What is even more important is the fact that as you move into CAE and CPE sentences completion exercises, common expressions and idioms become more and more important. So, this is an area the student should pay a lot of attention to.
The easiest way to understand how to use these expressions is to look at them in context:
in fact,
He is, in fact, a policeman.
instead of,
I would like beer instead of water.
part of,
This is part of the engine assembly.
made aware of
I was made aware of his behaviour yesterday.
due to,

the first to

by definition,
A dictatorship means, by definition, one centre of power.
go by bus,
I prefer to go by bus.
around the world,
The news went around the world.
named after,

not only but also,

more likely than not,

for good measure,

fall out with,

cover up,
It isn't the crime but the cover up that causes problems.
no matter what
