Present Simple vs. Past Simple – English Grammar Exercises for A1

1 (c) don’t drink

• Why it’s correct (The Key): “Anymore” and “now” indicate a present habit. The negative present simple for “I” is “don’t + base verb”.
• Error Analysis: (a) didn’t drink (Common Mistake: wrong tense for a current habit). (b) doesn’t drink (Strong Distractor: present tense, but wrong auxiliary for “I”). (d) not drink (Structural Error: missing the auxiliary “do”).

2 (b) drank

• Why it’s correct (The Key): “When we were at university” sets the time in the finished past. The past simple of the irregular verb “drink” is “drank”.
• Error Analysis: (d) drink (Common Mistake: forgetting to change the verb to past tense). (a) drinked (Structural Error: applying regular “-ed” to an irregular verb). (c) was drink (Strong Distractor: mixing “to be” with a base verb).

3 (d) put

• Why it’s correct (The Key): “In the past” signals the past simple. “Put” is an irregular verb that stays the same in the past tense.
• Error Analysis: (a) puts (Common Mistake: using present tense for a past action). (c) putted (Structural Error: adding “-ed” to an irregular verb). (b) are put (Strong Distractor: passive voice structure, wrong meaning here).

4 (a) don’t eat

• Why it’s correct (The Key): “Now” signals a current routine. The correct negative form is “don’t eat”.
• Error Analysis: (b) didn’t eat (Common Mistake: using past tense for a present situation). (d) not eat (Structural Error: missing “do”). (c) am not eat (Strong Distractor: mixing continuous auxiliary “am” with base verb).

5 (b) ordered

• Why it’s correct (The Key): “When we lived” indicates a past habit. “Order” is regular, so we add “-ed”.
• Error Analysis: (a) order (Common Mistake: failing to conjugate to the past). (c) ordering (Structural Error: using a gerund/participle without “to be”). (d) was order (Strong Distractor: incorrect attempt at past tense).

6 (c) do you drink

• Why it’s correct (The Key): “Now” requires a present simple question. For “you”, we use “do”.
• Error Analysis: (a) did you drink (Common Mistake: carrying the past tense from the first half of the sentence into the present half). (b) you drink (Structural Error: missing the auxiliary “do” for a question). (d) are you drink (Strong Distractor: incorrect grammar structure).

7 (a) don’t eat

• Why it’s correct (The Key): “These days” and “now” mean this is a current state.
• Error Analysis: (b) didn’t eat (Common Mistake: wrong tense). (d) doesn’t eat (Strong Distractor: correct tense, but wrong auxiliary for “I”). (c) haven’t eat (Structural Error: incorrect present perfect structure).

8 (d) came

• Why it’s correct (The Key): “Ten years ago” requires the past simple. “Come” is an irregular verb, becoming “came”.
• Error Analysis: (a) come (Common Mistake: leaving the verb in the present tense). (b) comed (Structural Error: applying “-ed” to an irregular verb). (c) did came (Strong Distractor: using “did” with the past form instead of the base form).

9 (b) don’t like

• Why it’s correct (The Key): “Anymore” (meaning ‘not now’) shows a present lack of preference.
• Error Analysis: (a) didn’t like (Common Mistake: wrong tense). (d) not like (Structural Error: missing “do”). (c) am not like (Strong Distractor: literal translation from other languages, grammatically incorrect).

10 (a) Did

• Why it’s correct (The Key): “When you were a teenager” is in the past. To ask a yes/no question about a past habit, we use “Did”.
• Error Analysis: (b) Do (Common Mistake: using present question word for a past context). (d) Were (Strong Distractor: “were” cannot be followed by the base verb “eat”). (c) Have (Structural Error: incorrect auxiliary for past simple).

11 (c) hated

• Why it’s correct (The Key): “As a kid” means this was a past state. We need the past affirmative “hated”.
• Error Analysis: (a) hate (Common Mistake: using present tense). (d) did hated (Structural Error: double past marking). (b) wasn’t like (Strong Distractor: students often confuse “wasn’t” and “didn’t” when trying to say “didn’t like”).

12 (b) had

• Why it’s correct (The Key): “Before” indicates a past habit. The past tense of “have” is “had”.
• Error Analysis: (a) have (Common Mistake: using present tense). (c) haved (Structural Error: regularizing an irregular verb). (d) did had (Strong Distractor: double past marking).

13 (d) don’t go

• Why it’s correct (The Key): “Not good now” shows a current change in behavior.
• Error Analysis: (a) didn’t go (Common Mistake: wrong time frame). (c) doesn’t go (Strong Distractor: wrong auxiliary for “I”). (b) not go (Structural Error: missing auxiliary).

14 (a) let

• Why it’s correct (The Key): “When we were kids” is past tense. “Let” is an irregular verb that does not change in the past tense.
• Error Analysis: (b) lets (Common Mistake: present tense for “my mother”). (d) letted (Structural Error: adding “-ed” to an irregular verb). (c) is let (Strong Distractor: passive voice, wrong meaning).

15 (b) don’t enjoy

• Why it’s correct (The Key): “Normally” indicates a general, present truth or habit.
• Error Analysis: (a) didn’t enjoy (Common Mistake: matching the past tense of the second clause incorrectly). (d) not enjoy (Structural Error: missing “do”). (c) am not enjoy (Strong Distractor: wrong verb structure).

16 (c) didn’t eat

• Why it’s correct (The Key): “Back in high school” is a past context. The negative past simple is “didn’t + base verb”.
• Error Analysis: (a) don’t eat (Common Mistake: using present tense for a past habit). (b) didn’t ate (Structural Error: double past marking). (d) wasn’t eat (Strong Distractor: confusing “was” with “did” as an auxiliary).

17 (d) don’t have

• Why it’s correct (The Key): “Look at the menu” (right now) means this is a present situation, even though they ordered it “last year”.
• Error Analysis: (a) didn’t have (Common Mistake: using past tense because of the words “last year”, ignoring the current context). (b) doesn’t have (Structural Error: “They” takes “don’t”, not “doesn’t”). (c) aren’t have (Strong Distractor: incorrect mixing of verbs).

18 (a) don’t drink

• Why it’s correct (The Key): The speaker is surprised by a current habit (“now?”).
• Error Analysis: (b) didn’t drink (Common Mistake: carrying past tense from “bought”). (d) doesn’t drink (Structural Error: wrong auxiliary for “You”). (c) aren’t drink (Strong Distractor: structurally invalid).

19 (b) didn’t know

• Why it’s correct (The Key): “When I lived alone” is in the past.
• Error Analysis: (a) don’t know (Common Mistake: wrong tense). (d) didn’t knew (Structural Error: double past marking – “didn’t” + past verb). (c) wasn’t know (Strong Distractor: confusing past auxiliaries).

20 (c) don’t want

• Why it’s correct (The Key): The speaker is refusing milk today (present).
• Error Analysis: (a) didn’t want (Common Mistake: using past tense because of the second sentence). (b) not want (Structural Error: missing “do”). (d) am not wanting (Strong Distractor: “want” is a state verb and is rarely used in continuous tenses at this level).

1. Finding the Timeline: Always look for time markers. Words like now, today, normally, these days signal the Present Simple (habits you have now). Words like in the past, when I was a kid, ten years ago, before signal the Past Simple (habits that are finished).
2. The “Didn’t” Rule (Negative Past): To say you didn’t do something in the past, use didn’t + base verb (e.g., I didn’t eat). Never put the main verb in the past tense if you already used “didn’t” (e.g., I didn’t ate is always wrong).
3. Irregular Verbs: Many common action verbs related to food and daily life are irregular and do not take “-ed” in the past. Remember: drink -> drank, eat -> ate, come -> came, have -> had. Some verbs don’t change at all: put -> put, let -> let.
4. Don’t Mix Auxiliaries: In the Present Simple, use don’t/doesn’t for negatives. In the Past Simple, use didn’t. Do not use “am not”, “isn’t”, “wasn’t”, or “weren’t” directly next to a base action verb (e.g., I wasn’t eat is incorrect; it must be I didn’t eat).
