Noun Clauses Practice Worksheet - Interactive Exercises for Identifying and Creating Noun Clauses

It looks like you've uploaded a worksheet titled "Noun Clauses Practice" from TeachThis, which focuses on identifying and using noun clauses in English grammar. Since I can't view images directly, I’ll help you solve the problems based on the text you've provided.

Let’s go through each section step by step and solve it.

---

A. Read the sentences and underline the noun clause in each sentence.

We are to identify the noun clause — a dependent clause that acts as a noun (subject, object, complement) and often starts with words like *that, whether, if, who, what, when, where, why, how*, etc.

1. I need to concentrate on what I'm doing.
→ Noun clause: what I'm doing
*(It's the object of "concentrate on")*

2. What he said made me very angry.
→ Noun clause: What he said
*(It's the subject of the sentence)*

3. He doesn’t know whether to trust her or not.
→ Noun clause: whether to trust her or not
*(Object of "know")*

4. Whenever I go, I see people chatting on their phones.
→ This is not a noun clause. “Whenever I go” is an adverbial clause (time).
→ No noun clause here.
*(Note: “whenever” introduces an adverb clause, not a noun clause.)*

5. Help yourself to whatever you want.
→ Noun clause: whatever you want
*(Object of "to")*

6. I want to know where I can buy a new hat.
→ Noun clause: where I can buy a new hat
*(Object of "know")*

B. Choose the subordinator that best completes each noun clause.

We are to pick the correct word to start the noun clause.

1. Jerry couldn't decide _______ / that he would accept the job or not.
→ Correct: whether
→ whether he would accept the job or not
*(“whether...or not” is a common structure)*

2. Whose / Wherever he goes, at night it is a mystery to us.
→ The sentence should be: Wherever he goes, at night it is a mystery to us.
→ But this isn’t a noun clause — it’s an adverbial clause.
→ Wait — the sentence seems awkward. Likely intended:
→ Whoever he is, it is a mystery to us.
→ But given options: Whose doesn't make sense.
→ Probably a typo. If it's “Whichever”, still not right.
→ Best fit: Whoever — but not listed.
→ Given options: Whose / Wherever — Wherever fits grammatically, but doesn't make full sense.
→ Let's assume the intended answer is Wherever — though the meaning is unclear.

✔ But likely the sentence is meant to be:
"Whoever he is, it is a mystery to us."
→ So if “Whose” is incorrect, perhaps it's Whoever? But it's not listed.
→ Perhaps it's: Wherever he goes, it is a mystery to us.
→ Then the answer is Wherever.

→ Answer: Wherever

3. Paulo was sad about / that his friend had moved away.
→ The correct subordinator is that
→ that his friend had moved away
→ (This is a noun clause acting as the object of "sad about")

→ Answer: that

4. I would love to learn how / when I want to speak Japanese.
→ The correct one is how
→ how to speak Japanese
→ “when” doesn’t fit logically.

→ Answer: how

5. What / That he did was against the law.
→ “That he did” is not correct — it lacks a noun.
→ The correct phrase is What he did — "what" refers to the action.
→ So: What he did was against the law.
→ Answer: What

6. Dad started shouting when / after I told him the news.
→ This is not a noun clause — it's an adverbial clause.
→ But we're choosing between “when” and “after”. Both are possible, but “when” is more natural.
→ However, this isn’t a noun clause — so maybe this question is mislabeled?

→ But the instruction says “complete each noun clause.”
→ So likely, the sentence is missing a noun clause.
→ Maybe: “Dad started shouting because I told him the news.”
→ But given options: “when” or “after” — both work for time, but again, not noun clauses.

→ Conclusion: This is not a noun clause.
→ But if forced to choose: when is more common.

→ Answer: when

7. We will give the award to who / whoever finishes first.
→ Correct: whoever
→ “whoever” is the subject of the clause “whoever finishes first”
→ “who” is incorrect here — it would require a verb.

→ Answer: whoever

C. Put the words in the correct order to create sentences that have noun clauses.

We need to form grammatically correct sentences with noun clauses.

1. him / he / whatever / wanted / he / told / could / have / I
→ Rearranged: I told him he could have whatever he wanted.
→ Noun clause: whatever he wanted (object of "have")

2. dangerous / did / what / very / Sam / was
→ Rearranged: What Sam did was very dangerous.
→ Noun clause: What Sam did (subject of sentence)

3. me / pasta / showed / how / to / Sam / cook
→ Rearranged: Sam showed me how to cook pasta.
→ Noun clause: how to cook pasta (object of "showed")

4. the / cancelled / nobody / us / that / match / told / been / had
→ Rearranged: Nobody told us that the match had been cancelled.
→ Noun clause: that the match had been cancelled (object of "told")

Summary of Key Concepts:

- Noun clauses act as nouns (subject, object, complement).
- They often begin with that, whether, if, who, what, when, where, why, how.
- "Whether" is used for yes/no questions; "if" can be used in some cases but not always.
- "Whatever", "whoever", "whichever" are pronouns that introduce noun clauses.
- Word order matters — especially in subject-verb agreement and clause structure.
