Understanding Past Simple Negative Forms

The question asks us to complete the sentence "I went to Paris last year but ______" using the correct grammatical form. The first part of the sentence, "I went to Paris last year," uses the past simple tense ("went"). The conjunction "but" indicates a contrast or an exception, implying that something else did not happen or is different from the first statement, also likely referring to the past.

We need to choose the option that correctly forms a negative statement in the past tense to fit the context.

Analyzing the Options for Past Simple

• Option 1: did not go
  This option uses the auxiliary verb "did" (past tense of "do") followed by "not" and the base form of the main verb "go". This is the standard structure for forming the negative in the past simple tense in English. The sentence would be "I went to Paris last year but did not go back again." This makes grammatical sense and fits the context.
• Option 2: did not went
  This option is grammatically incorrect. When using the auxiliary verb "did" (or "did not") in the past simple, the main verb must be in its base form (infinitive without "to"). "Went" is the past tense form, so using "did not went" is a common error called double past marking.
• Option 3: never go
  "Go" is in the base form/present tense. While "never" can be used with the past simple (e.g., "I never went there"), "never go" uses the present tense verb. The sentence is clearly about a past event ("went to Paris last year"), so a present tense form is inappropriate here.
• Option 4: never went
  This option uses "never" followed by the past tense verb "went". "Never went" is a valid phrase in the past simple. However, "did not go" is the more direct and common way to simply negate a specific action in the past ("...but I didn't go back"). While "never went" could potentially fit certain contexts (e.g., "I went to Paris last year but I never went to the Eiffel Tower"), in the general sense of not repeating the action of 'going' associated with the trip, "did not go" is the most fitting and standard completion. The phrasing "but did not go" naturally implies "but did not go back" or "but did not go again".

Forming the Past Simple Negative

The rule for forming negative sentences in the past simple tense for most verbs (except "be") is:

$\text{Subject} + \text{did} + \text{not} + \text{base form of the main verb} + \text{rest of the sentence.}$

Sometimes "did not" is contracted to "didn't".

For example:

• Positive: I played football yesterday.
• Negative: I did not play football yesterday. (or I didn't play football yesterday.)
• Positive: She saw the movie.
• Negative: She did not see the movie. (or She didn't see the movie.)

In our sentence, the subject is "I", the auxiliary is "did not", and the main verb is "go" (base form of "went"). This matches the structure of Option 1.

Conclusion on the Correct Option

Based on the rules of past simple negative formation and the context of the sentence, "did not go" is the only grammatically correct and natural option to complete the sentence.

Additional Information: Common Past Tense Errors

A common mistake when forming the past simple negative is to use the past tense form of the main verb after "did not". Remember that "did" already carries the past tense information, so the main verb reverts to its base form.

• Incorrect: They didn't saw him.
• Correct: They didn't see him.
• Incorrect: She did not ate the cake.
• Correct: She did not eat the cake.

Always use the base form of the verb after "did not" or "didn't" in the past simple negative.
