Instructions: Read each prompt carefully and use precise grammatical terms where you can. Write your answers in the boxes; for editing questions, make the smallest change that produces correct, effective Standard English.

Independent or Subordinate?

Decide whether the bold clause in each sentence is independent or subordinate. An independent clause can stand alone as a complete sentence; a subordinate clause cannot. Write your answer in each box.

1. Although the rain had stopped, the match continued.

2. The lantern flickered as the wind rattled the shutters.

3. The final bell rang, and the pupils hurried outside.

4. Whoever arrives first should save us a seat.

Identify the Sentence Type

Classify each sentence by its purpose: declarative, interrogative, imperative or exclamatory. Use the sentence’s structure and punctuation as clues. Write one term in each box.

1. Please place your completed work on the front desk.

2. What a remarkable view that is!

3. Have you checked the final paragraph?

4. The library closes at half past four.

Punctuation for Effect

Choose the punctuation mark that best completes each sentence. Consider the relationship between the clauses and the effect the writer wants. Write the punctuation mark in the box.

1. The corridor was silent ___ every classroom door was closed. Use a colon to introduce an explanation.

2. I had packed everything ___ my notebook was still on the desk. Join two closely related independent clauses with a semi-colon.

3. The answer ___ surprisingly ___ was correct. Set off the parenthesis with brackets.

4. She opened the envelope ___ and froze. Use a dash to create a dramatic pause.

Edit for Standard English

Rewrite each sentence in Standard English, correcting the grammatical error while keeping the original meaning. Pay particular attention to subject–verb agreement and pronoun choice. Write the corrected sentence in each box.

1. Me and Sam was waiting outside the hall.

2. The group of players are ready for the photograph.

3. Her and I have finished the science display.

4. We was told to bring our reading books.

Combine Clauses Precisely

Join each pair of ideas into one complex sentence using the subordinating conjunction shown. Add any necessary punctuation. Your sentence should preserve both ideas and read fluently.

1. The lights went out. The audience remained calm. Use although.

2. I will return the book. I have finished reading it. Use when.

3. The dog barked loudly. Someone approached the gate. Use because.

4. The team practised every afternoon. They wanted to improve their passing. Use so that.

Punctuation and Meaning

Each sentence contains a punctuation choice that changes how the reader understands or hears it. Rewrite each sentence with the punctuation specified, preserving the words and making the intended meaning clear.

1. Rewrite with a colon to introduce the list: Bring three things to the trip a coat, a packed lunch and a water bottle.

2. Rewrite with an ellipsis to show that the speaker trails off: I thought I heard someone in the garden.

3. Rewrite with a pair of dashes around the parenthesis: The old bridge which had been closed for months reopened today.

4. Rewrite as a question using a question mark: You have finished the report.
