English worksheets: exam for grade 12 - Free Printable

Let’s go through each question one by one. I’ll explain what’s being asked and how to pick the right answer — like we’re solving it together in class.

---

Question 1:
> Choose the word that best completes the sentence:
> “I think _______ I wouldn’t have done that at school.”
> Options: a) since, b) if, c) when, d) though

This is about choosing the right connecting word (conjunction). The sentence sounds like someone is saying, “If I were in your place, I wouldn’t have done that.” So we need a word that introduces a condition — that’s “if”.

✔ Correct answer: b) if

---

Question 2:
> “When _______ at 80 degrees Celsius, water boils.”
> Options: a) heats, b) heating, c) heated, d) to heat

We’re talking about water being heated — so it’s passive voice. Water doesn’t heat itself; something heats it. So we say “when heated” = “when it is heated”.

✔ Correct answer: c) heated

---

Question 3:
> “The boys _______ down to listen to the lesson.”
> Options: a) sat, b) set, c) sit, d) sets

“Sit” means to rest on your bottom. “Set” means to put something down. Here, the boys are sitting down to listen. Past tense? Yes — because the sentence is describing something that already happened (“to listen to the lesson” implies past action).

So: “sat” is past tense of “sit”.

✔ Correct answer: a) sat

---

Question 4:
> “_______ is very crowded in this month.”
> Options: a) Traffic, b) Traffics, c) Trffic, d) Trafic

First, spelling: “Traffic” is spelled T-R-A-F-F-I-C. No plural form needed here — traffic is uncountable. We don’t say “traffics”. And options c and d are misspelled.

✔ Correct answer: a) Traffic

---

Question 5:
> “Does _______ sugar do you need for making a cake?”
> Options: a) many, b) much, c) few, d) little

Sugar is uncountable — you can’t count individual grains easily. For uncountable things, we use “much”, not “many”. Also, “few” and “little” are used with negative or limiting meanings, but here it’s just asking quantity.

✔ Correct answer: b) much

---

Question 6:
> “The flight was delayed _______ the large number of passengers.”
> Options: a) due to, b) because, c) because of, d) as result of

“Because” must be followed by a full clause (subject + verb), like “because there were many passengers”. But here we have “the large number...” — that’s a noun phrase. So we need “because of” or “due to”. Both work, but let’s check options:

- “due to” → correct grammar here
- “because of” → also correct
Wait — both a and c seem okay? Let’s look again.

Actually, “due to” is often used after “be” verbs (like “was due to”), which fits here: “The flight was delayed due to...”

“Because of” also works: “delayed because of...”

But in standard tests, “due to” is preferred after “was/were” when explaining cause.

Also, option d says “as result of” — should be “as a result of”, so it’s wrong.

Between a and c — both grammatically acceptable, but “due to” is more formal and commonly tested in this structure.

Wait — actually, modern usage accepts both. But let’s see the exact wording: “delayed ___ the large number...”

In most textbooks, “due to” is taught for this case.

BUT — hold on! Actually, “because of” is more natural in spoken English. However, since this is a test, and “due to” is listed first, and matches the structure “was delayed due to”, I’ll go with a).

Wait — let me double-check.

Actually, many sources say “due to” modifies nouns, “because of” modifies verbs. Here, “delayed” is a verb (past participle), so “because of” might be better.

Hmm… tricky.

Let’s think: “The delay was due to…” → correct.
“The flight was delayed because of…” → also correct.

But in multiple choice, if both are present, sometimes they expect “because of” for actions.

Looking back at the options:
a) due to
c) because of

Both could be argued. But in many standardized tests, “because of” is preferred when modifying a verb phrase like “was delayed”.

Actually, let’s check real examples:

- “The game was canceled because of rain.” ✔
- “The cancellation was due to rain.” ✔

Here: “The flight was delayed [verb] ___ the large number...” → so “because of” is better.

I think I made a mistake earlier.

✔ Correct answer: c) because of

*(Note: Some style guides accept both, but for school-level tests, “because of” is safer here.)*

Question 7:
> “I thought a _______ would be useful for my project.”
> Options: a) computer, b) computor, c) compute, d) computes

Spelling: “computer” is correct. “Computor” is old/incorrect spelling. “Compute” is a verb. “Computes” is third person verb.

We need a noun — thing that is useful for a project → computer.

✔ Correct answer: a) computer

---

Question 8:
> “What I think high school _______ should be E-U University.”
> Options: a) graduate, b) graduates, c) graduating, d) graduated

Subject: “high school _______” — who should be E-U University? That doesn’t make sense. Wait — probably typo? Maybe “should attend E-U University”?

Assuming it’s “high school graduates” — meaning students who finished high school.

“Graduates” is plural noun — makes sense: “What I think high school graduates should do...”

Option a: “graduate” — singular, but “high school graduate” would be one person — possible, but less likely.

Option b: “graduates” — plural, matches “what I think [they] should...”

Also, “graduating” is adjective/verb form — doesn’t fit. “Graduated” is past tense verb — no.

So between a and b — “graduates” is better because it refers to the group.

✔ Correct answer: b) graduates

---

Question 9:
> “Almost cars that will be created will be electric. It _______ clearly.”
> Options: a) can see, b) sees, c) saw, d) should be seen

Cars won’t see anything — people see. So “it” refers to the fact that cars will be electric — that fact should be visible/clear.

So passive voice: “It should be seen clearly” — meaning, it ought to be obvious.

“Can see” — active, needs subject like “we can see”

“Sees” — active, third person — “it sees” doesn’t make sense

“Saw” — past tense — doesn’t fit future context

✔ Correct answer: d) should be seen

---

Question 10:
> “I _______ two packages from the post office today. Did you get yours?”
> Options: a) have picked up, b) had picked up, c) am picking up, d) was picking up

Time marker: “today” — present perfect is good for actions completed recently with present relevance.

“Have picked up” — present perfect → correct.

“Had picked up” — past perfect — needs another past event, e.g., “before you called”

“Am picking up” — present continuous — happening now, but sentence says “today” and asks “did you get yours?” — implies completion.

“Was picking up” — past continuous — ongoing in past, not completed.

✔ Correct answer: a) have picked up

---

Now Part B: Rewrite sentences according to instructions.

1. He has been studying all day. (Use Present Perfect Continuous)
→ Already in Present Perfect Continuous! So maybe they want us to keep it same? Or perhaps rephrase slightly?

Wait — instruction says “rewrite... according to the instructions between brackets”. Bracket says: “(Use Present Perfect Continuous)” — but it’s already in that tense.

Maybe it’s a trick? Or perhaps they want confirmation.

Actually, looking again: the original sentence IS in Present Perfect Continuous. So rewriting it the same way is fine.

But maybe they meant to change it? No — instruction is clear: use that tense — which it already does.

Perhaps it’s testing if student recognizes it’s already correct.

But to follow instruction literally: rewrite using that tense → same sentence.

✔ Answer: He has been studying all day.

*(No change needed — it’s already correct.)*

---

2. I never had time to important appointment. (Use “wish”)
Original has error: “to important appointment” → probably meant “to make an important appointment” or “for an important appointment”

Assume intended meaning: “I never had time for an important appointment.”

Now, use “wish” — to express regret about past.

Structure: “I wish I had had time for an important appointment.”

Yes — past perfect after “wish” for past regrets.

✔ Answer: I wish I had had time for an important appointment.

---

3. Women and men are equally capable. (Use as...as)
Compare equality: “as + adjective + as”

So: “Women are as capable as men.”

Or: “Men are as capable as women.” — either is fine, but usually we keep order similar.

Original: “Women and men are equally capable.” → so “Women are as capable as men.”

✔ Answer: Women are as capable as men.

---

4. You cannot win unless you try. (Use only...if)
“Unless” means “if not”. So: “You cannot win if you do not try.”

Now, use “only...if”: This means the condition is necessary.

“You can win only if you try.”

Yes — that’s the standard transformation.

✔ Answer: You can win only if you try.
