Lesson 1 – Systems: Review / Study Tips


Forming questions using the past simple.  

E.g. When did you carry out the rescue?  We carried out the rescue on 18 July.

Relative Pronouns 

We use relative pronouns:

  • to join two sentences together
  • after a noun, to make clear which person or thing we are talking about
  • tell us more about a person or thing

We use:

  •  who and whom for people
  • which for things
  • Or we can use that for people or things
  • where for location
  • from where for movement from a specific location

In non-defining relative clauses we separate the two clauses using a comma
