English grammar worksheet focusing on simple past, simple present, and will-future tenses with fill-in-the-blank exercises.

Let's solve each sentence by identifying the correct verb tense based on signal words (like *last week*, *always*, *next year*, *yesterday*, etc.) and context. We'll use:

- Simple Past: for completed actions in the past (e.g., *last week*, *yesterday*, *two days ago*).
- Simple Present: for habits, general truths, or routines (e.g., *always*, *every day*, *often*).
- Will-Future: for future predictions or intentions (e.g., *next year*, *if...*, *please*).

m) My classmate always reads books.

n) What would you think, if your brother stole your money?
👉 Conditional: "if your brother stole" = hypothetical past → *would think*; "stole" is past subjunctive (used for unreal situations).
👉 This is a second conditional structure: *If + past simple, would + base verb*. So: *would think*, *stole*

o) Why are you here now?
👉 "Now" = present → Simple Present → *are*

p) I did not hear you because I was listening to music.
👉 "Was listening" = past → so *did not hear* (Simple Past)

q) We cleaned your apartment after you had had a party there.
👉 "After you had had..." implies the cleaning happened in the past → Simple Past → *cleaned*

r) Last night we could not stand the smoke.
👉 "Last night" = Simple Past → *could not stand* (modal verb past form)

s) Why do you always talk about me?
👉 "Always" = habit → Simple Present → *do* + *talk*

t) If you leave, I will miss you.

v) My sister waters the plants every day.
👉 "Every day" = routine → Simple Present → *waters*

w) Last Christmas I did not get any presents.
👉 "Last Christmas" = Simple Past → *did not get*

x) In the evenings my parents do not play cards.
👉 "In the evenings" = habitual → Simple Present → *do not play*

y) Don’t I know you? I haven’t met you before.
👉 This is a negative question expressing surprise. But grammatically:
→ It should be: "Don't I know you?" — but this is unusual.
Actually, the correct form is: "Don't I know you?" → But it's more natural as: "Don't I know you?" → Actually, this is a tag question mistake.

Wait: The intended meaning is: "I don't know you" — but the speaker says: "Don't I know you?" → That’s incorrect.

But the sentence says: "Don’t I know you? I haven’t met you before."
This is logically inconsistent — if you haven't met someone, you don't know them, so saying “Don’t I know you?” doesn't make sense.

But grammatically, it’s asking: "Is it true that I know you?" → Answer: No, I haven’t met you.

So the correct structure is:
👉 Don’t I know you? → This is not standard. The correct tag would be:
"I don’t know you, do I?"
But here, the sentence is likely meant to be:
👉 Don’t I know you? — which is incorrect grammar.

Alternatively, perhaps it's a typo. But assuming it's asking for the correct verb form:
Since the speaker hasn’t met the person, they don’t know them.
So: Don’t I know you? → But this is awkward.

Actually, the correct way to express this idea is:
"I don’t know you, do I?" — but here, it's written as:
"______ I ______ (know) you? I haven’t met you before."

So the correct answer is:
👉 Don’t I know you? — but this is not natural.

Wait: Let's analyze:
The speaker wants to say: “I don’t know you.” But they’re asking it as a question.
So the correct negative question is:
👉 Don’t I know you? → This is grammatically incorrect.

Standard English:
To ask "I don’t know you" as a question:
→ "I don’t know you, do I?"
Or: "Do I know you?" → then answer: "No, I haven’t met you before."

But here, the blank is: "______ I ______ (know) you?"

So the correct form is:
👉 Don’t I know you? → Incorrect
Better: Don’t I know you? is not used.

Actually, the correct form for this context is:
👉 Do I know you?
Then: "No, I haven’t met you before."

But the sentence says: "______ I ______ (know) you? I haven’t met you before."
So the only logical answer is:
👉 Do I know you?
Because if the speaker has never met you, they are asking: “Do I know you?”

So:
👉 Do I know you?
(Yes, that makes sense.)

But the word “don’t” is not in the verb, so it must be:
👉 Do I know you?

So:
y) Do I know you? I haven’t met you before.
✔ Correct.

z) Please, help me.
👉 Imperative command → Simple Present (imperative) → *help*
