Question

Identify the complete adverb clause. Let's write our compositions now so that we can go to the basketball game.

Answer 1

The adverb clause in this sentence is "so that we can go to the basketball game". It explains the main verb "write" more thoroughly, and gives us an explanation "why" they have to do finish their composition.

Answer 2

The adverbial clause is "so that we can go to the basketball game". This adverbial clause is introduced by the subordinating conjunction "so that" indicating that it is an adverbial clause of purpose.

Adverbial clauses of purpose introduced by "SO THAT" are always followed by a modal expression such as CAN, WILL, COULD, etc.
