Linking and sequencing events
These words can be used to put events in sequence: when,
  after, after that,
  afterwards, next,
  subsequently, later (on),
  followed by, to go on to and
  finally.
When and after are
  conjunctions, and they are used to join two clauses. The subordinate clause
  beginning with when or after
  can go before or after the main clause.
  -  When she finished
    high school, she got a job cleaning houses.
-  She got a job cleaning houses when
    she finished high school.
-  After he heard
    the news, he went home.
-  I turned on the TV after I had finished
    dinner.
After can be used with verb + -ing.
  -  After hearing
    the news, he went home.
-  I turned on the TV after having
    finished dinner.
After that and afterwards
  are used as adverbs, to sequence two events. After
  that is used when describing a list of two or more events. Afterwards
  means "after an event that has just been mentioned."
  -  She first worked in a hospital, and after that
    she opened her own shop.
-  We went to see a movie, and afterwards we
    discussed it.
After is not usually used alone as an adverb.
  - She first worked in a hospital, and after
    she opened her own shop. 
-  We went to see a movie, and after we
    discussed it.
 Next and subsequently
  are used as adverbs. Next means "immediately
  after." Subsequently means "after that"
  or "at a later date." Subsequently is
  more formal than next, and is usually used in written
  English. 
  - He wrote a letter, and next he finished reading
    a novel.
- She wrote her first book when she was 25 years old,
    and subsequently she wrote five more.
 Later and later on
  are used as adverbs. Later means "after a
  particular time or event," but not necessarily immediately. Later
  on means "later in a period of time."
  -  I hated math in school, but later I found
    it useful.
- We first went to the movies, and later on we
    had dinner together.
Other ways of talking about a sequence of events:
-followed by is used to join two clauses in the
  middle, but not at the beginning, of a sentence.
  - She worked in a series of part-time jobs, followed
    by time working for a small construction company. 
 NOT: Followed by time working
  for a small construction company, she worked in a series of part-time jobs.
-to go on to do something can be used in any tense,
  and it is followed by the infinitive with to.
  -  She went on to become a private investigator.
-  When I finish college, I'll go on to establish
    my own company.
-  If he hadn't died so young, he would have gone
    on to become really famous.
