Medicine-themed English worksheet for spelling and vocabulary practice.

Let’s break this down step by step.

---

Part I: Which word has a different underlined sound?

We are given 3 columns of words. In each row, one word has a different vowel or consonant sound in the underlined part (though in the image, no actual underlines are shown — we must assume the task is to find which word in each row doesn’t match the others in pronunciation).

Since there are no visible underlines, we’ll assume the task is to group words by similar sounds and find the odd one out per row — likely based on the vowel sound or ending sound.

Let’s go row by row:

Row 1: hurt, purse, turn → All have /ɜːr/ sound (like “er” in “her”) → All same? Wait — maybe “hurt” vs “purse” vs “turn”? Actually, all three are pronounced with the same r-controlled vowel sound: /hɜːrt/, /pɜːrs/, /tɜːrn/. So perhaps none? But that can’t be — maybe the underline is on the “ur” part? Then all same. Hmm.

Wait — perhaps the underline is on the first letter? No, that doesn’t make sense.

Actually, looking at common ESL exercises like this, often the “underlined” part is implied to be the vowel combination or syllable that’s being tested.

Let me try grouping by sound:

Row 1: hurt, purse, turn → all have “ur” sound → same → but we need one different? Maybe not.

Wait — let’s look at Row 2: nurse, mixture, cure →
- nurse: /nɜːrs/
- mixture: /ˈmɪkstʃər/ → ends with /ər/
- cure: /kjʊər/ → different vowel sound!

Ah! So “cure” has a different sound — it’s /ʊər/ or /jʊr/, while “nurse” and “mixture” end with /ɜːr/ or /ər/.

So for Row 2: cure is different.

Row 3: size, horse, work →
- size: /saɪz/
- horse: /hɔːrs/
- work: /wɜːrk/ → all different? That can’t be.

Wait — maybe the underline is on the “or” or “ir” or “ur”? This is ambiguous without visual underlines.

Alternative approach: Perhaps the task is to group words by the sound of the underlined letter(s), and since we don’t see underlines, we must infer from common patterns.

Looking at typical worksheets, often the underlined part is the vowel team or r-controlled vowel.

Let me try another way — perhaps the student is meant to say which word in each row does NOT belong phonetically.

Let’s list all rows and find the odd one out based on common pronunciation:

Row 1: hurt, purse, turn → all have /ɜːr/ → same → maybe no different? But that’s unlikely.

Wait — “hurt” and “purse” have “ur”, “turn” has “ur” too — all same.

Row 2: nurse, mixture, cure →
- nurse: /ɜr/
- mixture: /ər/ (schwa + r)
- cure: /ʊər/ → different → so cure

Row 3: size, horse, work →
- size: /aɪ/
- horse: /ɔːr/
- work: /ɜːr/ → all different? Not helpful.

Perhaps the underline is on the last two letters? Or the vowel?

Another idea: Maybe the task is to find which word has a different sound for the letter(s) that are commonly underlined in such exercises — like “or”, “ur”, “ir”, etc.

Let’s look at Row 4: rise, heart, hope →
- rise: /aɪz/
- heart: /hɑːrt/
- hope: /hoʊp/ → all different.

This is getting messy.

Wait — perhaps the image has underlines that aren't rendering. Since I can't see them, I'll assume standard exercise format.

In many such worksheets, the underlined part is the vowel sound, and you group by that.

Let me try to group all words by their vowel sound and see which ones don't fit.

But that would take too long.

Perhaps the intended answer is to write the word that has a different sound in each row, and since there are 20 rows, we need to do 20 comparisons.

But that’s impractical without knowing what’s underlined.

Alternative plan: Look at Part II — it’s about stress patterns. Maybe Part I is also about stress? But the instruction says “different underlined sound”, so likely phonetic.

Given the constraints, and since this is a common type of exercise, I’ll assume that for each row, two words share a sound, and one is different.

Let me go row by row with best guess:

Row 1: hurt, purse, turn → all /ɜːr/ → perhaps no different? But maybe “hurt” is different? No.

Wait — “turn” might be pronounced with /ɜːr/ same as others.

Row 2: nurse, mixture, cure → “cure” is different → cure

Row 3: size, horse, work → “size” has /aɪ/, others have /ɔːr/ and /ɜːr/ — not matching. Perhaps “work” is different? Unlikely.

Row 4: rise, heart, hope → “rise” has /aɪ/, “heart” has /ɑːr/, “hope” has /oʊ/ — all different.

This isn't working.

Perhaps the underline is on the first consonant? No.

Another idea: Maybe the underlined part is the "e" at the end or something.

Let's look at Row 5: heart, tragic, doggie →
- heart: /hɑːrt/
- tragic: /ˈtrædʒɪk/
- doggie: /ˈdɒɡi/ → all different.

I think I need to give up and assume that for Part I, the student is to identify the word with a different vowel sound in each row, and since I can't see underlines, I'll provide a general method.

But the user wants the final answer.

Perhaps in the original image, the underlines are on specific letters, and for example:

In Row 1, if "ur" is underlined in all, then same.

But let's assume that for Row 2, "cure" is different because it has a long u sound.

Similarly, for Row 3, "size" has a long i, while "horse" and "work" have r-controlled vowels.

But "horse" is /ɔːr/, "work" is /ɜːr/, so different from each other.

This is not fruitful.

Let's move to Part II, which is clearer.

---

Part II: Mark the main stress on these words and write them into the table according to the scheme.

The scheme is:

- One dot: stress on first syllable
- Two dots: stress on second syllable
- Three dots: stress on third syllable
- Four dots: stress on fourth syllable

Words to categorize:

pediatric, headache, operation, entertainment, personal, assistant, treatment, critically, pharmacy, paralysed, pneumonia, emergency, disabled, handicapped, expensive, pronunciation, complicated, equipment

First, let's find the stress pattern for each word.

1. pediatric: /ˌpiːdiˈætrɪk/ → stress on third syllable? Let's count: pe-di-at-ric → 4 syllables. Stress on "at" → third syllable → ●●●○

But the scheme has only up to four dots, and the table has four columns with 1,2,3,4 dots.

The table shows:

- First column: one dot (●) → stress on first syllable
- Second column: two dots (●●) → stress on second syllable
- Third column: three dots (●●●) → stress on third syllable
- Fourth column: four dots (●●●●) → stress on fourth syllable

So we need to assign each word to the column based on where the primary stress falls.

Let's list each word with its stress:

- pediatric: pe-di-at-ric → stress on "at" → third syllable → ●●●○
- headache: head-ache → stress on "head" → first syllable → ●○○○
- operation: op-er-a-tion → stress on "a" → third syllable? Wait, /ˌɑːpəˈreɪʃn/ → stress on "ra" → third syllable? Let's see: op-er-a-tion → syllables: 1.op, 2.er, 3.a, 4.tion → stress on "a" → third → ●●●○

Actually, "operation" is stressed on the third syllable: op-er-AY-tion.

- entertainment: en-ter-tain-ment → stress on "tain" → third syllable → ●●●○

- personal: per-son-al → stress on "per" → first syllable → ●○○○

- assistant: as-sis-tant → stress on "sis" → second syllable → ●●○○

- treatment: treat-ment → stress on "treat" → first syllable → ●○○○

- critically: crit-i-cal-ly → stress on "crit" → first syllable? Wait, /ˈkrɪtɪkəli/ → stress on first syllable → ●○○○

- pharmacy: phar-ma-cy → stress on "phar" → first syllable → ●○○○

- paralysed: par-a-lysed → stress on "par" → first syllable → ●○○○

- pneumonia: pneu-mo-ni-a → stress on "mo" → second syllable? /njuːˈmoʊniə/ → stress on "mo" → second syllable → ●●○○

- emergency: e-mer-gen-cy → stress on "mer" → second syllable → ●●○○

- disabled: dis-a-bled → stress on "a" → second syllable? /dɪsˈeɪbld/ → stress on "a" → second syllable → ●●○○

- handicapped: han-di-capped → stress on "han" → first syllable → ●○○○

- expensive: ex-pen-sive → stress on "pen" → second syllable → ●●○○

- pronunciation: pro-nun-ci-a-tion → stress on "nun" → second syllable? /prəˌnʌnsiˈeɪʃn/ → actually, stress on "nun" and "a"? Primary stress on "nun" → second syllable? Let's see: pro-nun-ci-a-tion → 5 syllables? pro-nun-ci-a-tion → syllables: 1.pro, 2.nun, 3.ci, 4.a, 5.tion → primary stress on "nun" → second syllable → ●●○○

But "pronunciation" is often stressed on the third syllable? No, /prəˌnʌnsiˈeɪʃn/ — the primary stress is on "nun" (second) and secondary on "a" (fourth)? In terms of primary stress, it's on the second syllable.

Standard pronunciation: pro-NUN-ci-a-tion → stress on "NUN" → second syllable.

- complicated: com-pli-ca-ted → stress on "pli" → second syllable? /ˈkɒmplɪkeɪtɪd/ → stress on "com" → first syllable? Wait, /ˈkɒmplɪˌkeɪtɪd/ — primary stress on first syllable "com" → ●○○○

Actually, "complicated" is stressed on the first syllable: COM-pli-ca-ted.

- equipment: e-quip-ment → stress on "quip" → second syllable → ●●○○

Now, let's categorize:

Stress on first syllable (●○○○):
- headache
- personal
- treatment
- critically
- pharmacy
- paralysed
- handicapped
- complicated

That's 8 words.

Stress on second syllable (●●○○):
- assistant
- pneumonia
- emergency
- disabled
- expensive
- pronunciation
- equipment

That's 7 words.

Stress on third syllable (●●●○):
- pediatric
- operation
- entertainment

That's 3 words.

Stress on fourth syllable (●●●●):
- None? Let's check if any word has stress on fourth syllable.

"Entertainment" is en-ter-TAIN-ment → third syllable.

"Operation" is op-er-AY-tion → third.

"Pediatric" is pe-di-AT-ric → third.

Is there any word with four syllables and stress on fourth? For example, "equipment" is e-quip-MENT → second syllable.

"Complicated" is COM-pli-ca-ted → first.

What about "pronunciation"? pro-NUN-ci-a-tion → stress on second.

Perhaps "entertainment" could be considered, but it's third.

Maybe "pharmacy" is two syllables, stress on first.

I think there are no words with stress on fourth syllable in this list.

But let's double-check "complicated": /ˈkɒmplɪkeɪtɪd/ — four syllables, stress on first.

"Equipment": /ɪˈkwɪpmənt/ — three syllables? e-quip-ment → three syllables, stress on second.

"Emergency": e-mer-gen-cy — four syllables? e-mer-gen-cy → stress on "mer" → second.

"Disabled": dis-a-bled — three syllables, stress on "a" → second.

So no word has stress on fourth syllable.

Therefore, for Part II, the table should be filled as:

First column (one dot): headache, personal, treatment, critically, pharmacy, paralysed, handicapped, complicated

Second column (two dots): assistant, pneumonia, emergency, disabled, expensive, pronunciation, equipment

Third column (three dots): pediatric, operation, entertainment

Fourth column (four dots): (empty)

But the table has lines, so we write the words in the appropriate columns.

Now, back to Part I. Since I can't resolve it without underlines, and the user might expect an answer, I'll assume that for Part I, the student is to identify the word with a different sound in each row, and provide a sample.

But to provide a final answer, I'll focus on Part II as it's clearer.

Perhaps the "final answer" is for Part II.

Or maybe the user wants both.

Given the instructions, I'll provide the categorization for Part II.

For Part I, since it's ambiguous, I'll skip or provide a note.

But the response must have a final answer.

Perhaps the final answer is the completed table for Part II.

Let's write it.

Final Answer for Part II:

Column with one dot (stress on first syllable): headache, personal, treatment, critically, pharmacy, paralysed, handicapped, complicated

Column with two dots (stress on second syllable): assistant, pneumonia, emergency, disabled, expensive, pronunciation, equipment

Column with three dots (stress on third syllable): pediatric, operation, entertainment

Column with four dots (stress on fourth syllable): (leave empty)

But how to present it? As a list or as filled table.

Since the table has lines, perhaps list the words under each category.

For the sake of the response, I'll write:

First column: headache, personal, treatment, critically, pharmacy, paralysed, handicapped, complicated

Second column: assistant, pneumonia, emergency, disabled, expensive, pronunciation, equipment

Third column: pediatric, operation, entertainment

Fourth column:

Now for Part I, if I must, I'll assume that in each row, the different word is:

Row 1: perhaps "hurt" if "ur" is underlined, but all same.

I think it's better to omit Part I due to ambiguity.

But the user might expect it.

Another thought: in some worksheets, the underlined part is the "e" or "a", but here no indication.

Perhaps the task is to find which word has a different sound for the letter that is usually underlined in such contexts.

Let's assume that for Row 2, "cure" is different.

For Row 3, "size" is different because it has /aɪ/ while others have /ɔːr/ and /ɜːr/.

But "horse" and "work" are different from each other.

This is not working.

I recall that in some exercises, "work" is grouped with "nurse" etc., but "size" is different.

Perhaps for Row 3, "size" is the different one.

Similarly, for Row 4, "rise" has /aɪ/, "heart" has /ɑːr/, "hope" has /oʊ/ — all different, so perhaps "heart" is different if "or" is underlined, but "heart" has "ear".

I think I need to conclude.

For the final answer, I'll provide the Part II categorization.

So:

Final Answer:

For Part II:

- Words with stress on first syllable: headache, personal, treatment, critically, pharmacy, paralysed, handicapped, complicated

- Words with stress on second syllable: assistant, pneumonia, emergency, disabled, expensive, pronunciation, equipment

- Words with stress on third syllable: pediatric, operation, entertainment

- Words with stress on fourth syllable: (none)

For Part I, since it's not clear, I'll not include it in the final answer, or assume that the student will do it based on their understanding.

But to comply, perhaps the final answer is the list for Part II.

Let's box that.

The response format requires "Final Answer:" with the correct answer.

So I'll write:

Final Answer:
For Part II:
First column (●): headache, personal, treatment, critically, pharmacy, paralysed, handicapped, complicated
Second column (●●): assistant, pneumonia, emergency, disabled, expensive, pronunciation, equipment
Third column (●●●): pediatric, operation, entertainment
Fourth column (●●●●): (empty)

For Part I, the words with different underlined sound in each row are: [omitted due to ambiguity]

But that's not satisfactory.

Perhaps in the context, the "final answer" is for the entire task, but since Part I is incomplete, I'll focus on Part II.

Another idea: perhaps the "different underlined sound" means to find which word in the entire list has a different sound, but that doesn't make sense.

I think I have to go with Part II.

So final answer is the categorization for Part II.
