The idea in everyday life

Original practice sentences: A: The workshop opens at nine. B: Because the workshop opens at nine. C: The morning workshop.

The idea

A complete independent clause includes a subject, a finite verb and a complete thought. A dependent clause can have a subject and verb but leaves a relationship unfinished. These are conventions for the supplied formal written paragraph, not a judgment of a person’s intelligence or language variety.

Find subjects and complete clauses — worked practice

A complete independent clause includes a subject, a finite verb and a complete thought. A dependent clause can have a subject and verb but leaves a relationship unfinished. These are conventions for the supplied formal written paragraph, not a judgment of a person’s intelligence or language variety.

Original practice sentences: A: The workshop opens at nine. B: Because the workshop opens at nine. C: The morning workshop.

AMaterialBSupplied text
CaseOriginal practice sentences: A: The workshop opens at nine. B: Because the workshop opens at nine. C: The morning workshop.

Copy as plain text
  1. 1. 1. Locate

    Identify A’s subject and finite verb.

    You should see: Subject: the workshop; verb: opens.

  2. 2. 2. Compare

    Identify why B does not stand alone here.

    You should see: Because introduces a dependent reason without its main clause.

  3. 3. 3. Repair

    Complete B with a supplied action.

    You should see: Because the workshop opens at nine, we arrive at eight forty-five.

  4. 4. 4. Distinguish

    Explain why C is a phrase.

    You should see: It names a subject but supplies no finite verb or complete assertion.

Now change one thing

Choose the complete independent clause from The bus arrives or When the bus arrives. Enter the exact complete clause.

Your work

What to finish

A clause-classification sheet with two completed repairs.

Common mistake

Watch for this

The phrase needs a statement such as opens at nine. A comma alone cannot turn its subject phrase into a complete independent clause.

How can I tell I understand it?

Explain why a changed word group is or is not a complete formal written clause.
