ANSWER KEY & EXPLANATIONS
1 (a)
- The Key: am. Introducing a current job title (“the new Marketing Assistant”) requires the “to be” verb in the Present Simple with the subject “I”.
- Error Analysis: (b) was (Common Mistake: Using past tense for an ongoing situation). (c) be (Structural Error: Unconjugated verb). (d) is (Strong Distractor: Correct tense, but wrong subject agreement).
2 (c)
- The Key: was. “Before this job” indicates a finished past period, requiring the singular past tense “to be” verb.
- Error Analysis: (a) am (Common Mistake: Forgetting to backshift tense). (b) were (Strong Distractor: Incorrect subject agreement for past “to be”). (d) did (Structural Error: “did” cannot be used with a noun phrase like “a student”).
3 (b)
- The Key: talk. “In my current role” and “every day” imply a current habit/task. With the subject “I”, the base verb is used.
- Error Analysis: (d) talked (Common Mistake: Wrong tense). (a) talks (Strong Distractor: Adding ‘s’ for the wrong subject). (c) talking (Structural Error: Missing the “to be” verb).
4 (d)
- The Key: worked. “Last year” is a specific past time, requiring the Past Simple.
- Error Analysis: (a) work (Common Mistake: Keeping the verb in the present tense). (b) was work (Structural Error: Mixing “to be” with a main verb). (c) working (Structural Error).
5 (b)
- The Key: don’t have. A negative structure in the present talking about a current state (“I learn fast” later on is the clue).
- Error Analysis: (a) didn’t have (Common Mistake: Applying the wrong tense). (d) not have (Structural Error: Missing the auxiliary verb “do”). (c) am not have (Strong Distractor: Word-for-word translation mistake from other languages, grammatically incorrect).
6 (a)
- The Key: work. “Now” establishes a present context in the first clause, contrasting with “in 2021” in the second.
- Error Analysis: (b) worked (Common Mistake: Influenced by the past tense in the second clause). (d) am work (Structural Error). (c) works (Strong Distractor: Wrong subject agreement).
7 (c)
- The Key: Did. “At your last job” is in the past. The question auxiliary for Past Simple is “Did”.
- Error Analysis: (a) Do (Common Mistake: Using present tense to ask about the past). (d) Were (Strong Distractor: Using “to be” with the main verb “work”). (b) Are (Structural Error).
8 (d)
- The Key: didn’t like. The reason (“he was”) is in the past, so the feeling was also in the past. Negative past structure: didn’t + base verb.
- Error Analysis: (a) don’t like (Common Mistake: Wrong tense). (b) didn’t liked (Structural Error: Double past marking – using “didn’t” and adding “-ed” to the verb). (c) wasn’t like (Strong Distractor).
9 (a)
- The Key: do. Asking about a skill for a “current role” requires the Present Simple.
- Error Analysis: (b) did (Common Mistake: Using the wrong tense during an interview for a current position). (d) does (Strong Distractor: Wrong agreement for “you”). (c) are (Structural Error: “are” does not go with the base verb “speak”).
10 (b)
- The Key: led. “Two years ago” means the action is in the past. “Lead” is an irregular verb, and its past form is “led”.
- Error Analysis: (a) lead (Common Mistake: Forgetting to use the past tense). (c) leaded (Structural Error: Applying a regular “-ed” rule to an irregular verb). (d) did lead (Strong Distractor: Over-emphasizing unnecessarily in a standard narrative sentence).
11 (c)
- The Key: started. “My old company” implies a finished past job, so this clause needs the past tense.
- Error Analysis: (b) start (Common Mistake: Tricked by the present tense in the first clause). (a) starts (Strong Distractor: Correct singular agreement but wrong tense). (d) starting (Structural Error).
12 (a)
- The Key: went. “After university” is a past milestone. The past of “go” is “went”.
- Error Analysis: (b) go (Common Mistake: Not using the past tense). (c) goed (Structural Error: Applying a regular rule to an irregular verb). (d) was go (Strong Distractor).
13 (d)
- The Key: am. Describing one’s current personality requires the “to be” verb “am” with an adjective/noun phrase.
- Error Analysis: (a) have (Common Mistake: Often a literal translation like “I have an organized personality”). (c) was (Strong Distractor: Using the past tense changes the meaning to imply you are no longer organized). (b) do (Structural Error).
14 (b)
- The Key: don’t work. Describing a current work schedule (“Monday to Friday”). The negative for “I” is “don’t”.
- Error Analysis: (a) didn’t work (Common Mistake: Wrong tense). (c) not work (Structural Error: Missing auxiliary). (d) am not work (Strong Distractor).
15 (c)
- The Key: taught. “At my previous job” requires the past tense. The irregular past of “teach” is “taught”.
- Error Analysis: (a) teach (Common Mistake: Forgetting to backshift the tense). (b) teached (Structural Error: Adding “-ed” incorrectly). (d) was teach (Strong Distractor).
16 (a)
- The Key: did. Asking for the reason you left an old job (“leave your last job”) requires the past auxiliary “did”.
- Error Analysis: (b) do (Common Mistake: Using the present tense). (d) were (Strong Distractor: Using “to be” for the main verb “leave”). (c) had (Structural Error).
17 (b)
- The Key: was. The first clause contains “before” specifying an old title, requiring “to be” in the past.
- Error Analysis: (a) am (Common Mistake: Using the wrong tense because the second clause is present). (d) were (Strong Distractor: Wrong subject agreement). (c) did (Structural Error).
18 (c)
- The Key: does. “A typical day” is a singular subject describing a current routine, taking the auxiliary “does”.
- Error Analysis: (b) did (Common Mistake: Asking about the old office instead of the current one). (a) do (Strong Distractor: Wrong subject agreement). (d) is (Structural Error: “is” doesn’t go with the base verb “look”).
19 (a)
- The Key: was. Recounting the reason for resigning in the past. “The old office” is singular, so we use “was”.
- Error Analysis: (b) is (Meaning Trap: The office might still be far currently, but in a past narrative explaining why you quit, the tense should match the past action). (c) did / (d) had (Structural Errors).
20 (d)
- The Key: think. Stating a personal opinion in the present (“I think it is important”) to explain a past learning action (“took a course”).
- Error Analysis: (a) thought (Common Mistake: Matching the past tense of the second clause incorrectly). (b) thinking / (c) am think (Basic Structural Errors).
GRAMMAR POINTS TO REMEMBER
- Time Shifts in the Same Sentence: In interviews, you will often use structures like “I CURRENTLY am… but BEFORE I worked…”. Make a clear distinction:
- Present (Describing yourself/Current job): Use Present Simple (I am, I work, I don’t have).
- Past (Past experience/Reasons for leaving): Use Past Simple (I was, I worked, I didn’t like).
- Be Careful with Irregular Verbs: Past jobs require V2 (past tense). Remember keywords: lead -> led, teach -> taught, go -> went. Never add “-ed” to these verbs.
- Distinguish Auxiliary Verbs:
- Don’t say “I wasn’t have” (Incorrect), say “I didn’t have”.
- When asked about current skills: “Do you speak…”
- When asked about old jobs: “Did you work…” or “Why did you leave…”.
