Past Tenses

A. went ✓

This is the correct past tense form of "go." When talking about something that already happened ("last night"), you need the past tense verb.

Why the others are wrong:
- B. goed — Not a real word; "go" is irregular and doesn't follow the normal "-ed" ending pattern
- C. go — This is present tense, but the sentence says "last night" (past), so you need past tense
- D. goat — This is a noun (an animal), not a verb form at all

A. worked ✓

• The sentence describes a completed action in the past ("yesterday"), so you need past tense.
• "Worked" is the correct past tense form of "work."

Why the others are wrong:
- B. work – Present tense; doesn't match "yesterday"
- C. working – Present participle; needs an auxiliary verb like "was working"
- D. workt – Not a real English word; past tense of "work" is "worked," not "workt"

A. bought ✓
This is the correct past tense form of "buy." When a regular verb ends in a consonant + "y," you change the "y" to "i" and add "-ed" (buy → bought is actually irregular, but the spelling is correct).

B. buied ✗
This incorrectly adds "-ed" without removing the "y" first—you'd never have "ie" together like this in English.

C. buyed ✗
This keeps the "y" and just adds "-ed," which breaks the spelling rule for verbs ending in consonant + "y."

D. buy ✗
This is the base form (present tense). The sentence says "last month," so you need past tense.

A. had ✓
"Had" is the simple past tense of "have," which is correct here because the vacation already happened.

B. haved ✗
"Haved" isn't a real word—"have" doesn't follow the regular past tense pattern (add "-ed"). It's an irregular verb.

C. has ✗
"Has" is present tense (he/she/it has), but we need past tense for something that already occurred.

D. having ✗
"Having" is a gerund/present participle, not a complete verb form for this sentence structure.

A. ate ✓
This is the simple past tense form. Since "at the party" shows this happened in the past, you need the past tense verb.

B. eat ✗
This is present tense, but the event already happened ("at the party").

C. eated ✗
Not a real word. The past tense of "eat" is irregular—it's "ate," not "eated."

D. eating ✗
This is the present participle (used for ongoing actions like "they are eating"). It doesn't work here without a helping verb, and the sentence is about a completed action anyway.

Why A is correct:
"Was" is the past tense form of "to be" used with the singular subject "I." The sentence describes something that happened yesterday (past time), so you need a past tense verb.

Why the others are wrong:
- B (am): Present tense—doesn't match "yesterday"
- C (is): Present tense AND used with "he/she/it," not "I"
- D (were): Past tense, but used with "you/we/they," not "I"

Correct answer: A. were

• "You" is always plural in English, so it takes the plural past tense verb were (not the singular "was")
• The sentence is in past tense (describing something that already happened), so were is correct
• B (are) is present tense, not past
• C (was) is singular, but "you" is always plural
• D (be) is the base form and doesn't work in a completed sentence

Correct answer: A. was

• "Was" is the past tense of "to be," and "last year" is a past time marker, so we need the past tense.
• "Was" is also the correct form for the singular subject "she."

Why the others are wrong:
- B. is – Present tense, but "last year" tells us this happened in the past, not now.
- C. were – Past tense, but "were" is only used with plural subjects (they, we) or "you," not with "she."
- D. are – Present tense plural form; doesn't match either the past time or the singular subject.

Why A is correct:
"Was" is the past tense of "to be." Since the journey already happened, you need past tense. "He was tired" describes his state after something that's already over.

Why the others are wrong:
- B (be): This is the base form of the verb—it needs a helping verb like "will be" or "would be"
- C (are): This is plural ("they are")—but "he" is singular
- D (is): This is present tense, but the journey is finished (past)

Why A is correct:
Yesterday is past tense, so you need "was" (past tense of "to be").

Why the others are wrong:
- B (is) – Present tense; yesterday is not now
- C (were) – Past tense, but used with plural subjects (we, they, you) or "I"; "a day" is singular, so "was" is correct
- D (will be) – Future tense; yesterday already happened

Correct answer: were
- "Were" is the past tense form of "to be" for plural subjects (we, you, they). Since "we" is plural, we need "were."

Why the others are wrong:
- are – present tense, but the sentence says "yesterday" (past)
- am – present tense AND only used with "I," not "we"
- is – present tense AND only used with singular subjects (he, she, it), not "we"

Correct answer: were

• The sentence refers to the past ("but not anymore" signals this), so you need a past-tense verb.
• "Were" is the past tense of "to be" that matches the subject "you."

Why the others are wrong:

• is/am – These are present tense, but the sentence clearly describes something that happened in the past.
• is – Also wrong because "is" is only used with "he/she/it," not "you."
• am – Only used with "I," not "you."

A. were ✓

This is correct because "they" is a plural pronoun that needs a plural past-tense form of "to be." "Were" matches both requirements.

Why the others are wrong:
- B. is – singular present tense (use with "he/she/it"), but we need plural and past tense
- C. are – plural but present tense; the sentence says "last weekend" (past)
- D. be – base/infinitive form; doesn't work for any specific tense or person

A. went ✓ Correct
- "Went" is the past tense of "go," and the sentence uses "last summer" (a past time marker), so you need a past tense verb.

B. visit ✗ Wrong
- This is present tense, but the sentence clearly refers to the past ("last summer").

C. goed ✗ Wrong
- This isn't a real word. "Go" is an irregular verb, so its past tense is "went," not "goed."

D. going ✗ Wrong
- This is a present participle (part of continuous tenses like "am going"), not a simple past tense form needed here.

A. sang ✓
This is the simple past tense of "sing." Since the sentence describes something that already happened ("at the concert"), you need the past tense form.

B. sing ✗
This is the base/present tense form. It doesn't show the action is finished.

C. sung ✗
This is the past participle form, used with helping verbs like "has" or "had" (e.g., "has sung"), not alone.

D. singed ✗
This isn't a form of "sing." While "singe" is a different verb meaning to burn lightly, "singed" doesn't fit here.

A. cooked ✓

This sentence needs a past tense verb to show the dinner already happened. "Cooked" is the correct past tense form of "cook."

Why the others are wrong:
- B. cook – Present tense; doesn't match the past action described
- C. cooking – This is a gerund/present participle; you'd need "were cooking" or "are cooking" with a helping verb
- D. cookt – Not a real word; the past tense of "cook" is "cooked," not "cookt"

A. completed ✓

The sentence needs a past tense verb because "last night" is a finished time in the past. "Completed" is the correct past tense form of "complete."

Why the others are wrong:
- B. complete — This is present tense, but the action already happened
- C. completing — This is a gerund/present participle, not a conjugated verb form for this sentence
- D. completid — This is misspelled; "completed" is the correct spelling

A. met ✓
"Met" is the simple past tense of "meet." Since the sentence says "yesterday," you need past tense, and "met" is the correct irregular past form.

B. meet ✗
This is present tense, but the sentence clearly refers to a past event ("yesterday").

C. meeting ✗
This is a gerund/present participle—it's a noun or part of a continuous tense, not a standalone verb for this sentence.

D. meeted ✗
This isn't a real word. "Meet" is an irregular verb, so it doesn't follow the regular "-ed" ending rule (it becomes "met," not "meeted").
