To determine the best alternative to complete the sentence "He told the teacher that ___________________.", we should understand the context of reported speech. In English, when transforming direct speech into reported speech, certain grammatical rules must be followed:
- Tense Backshifting: The tense in the reported clause is usually shifted back one step in the past. For example, present simple becomes past simple.
- Pronoun Changes: Pronouns should be adjusted according to the perspective of the speaker.
Considering these rules, let's analyze the options:
- he was liked by the whole class: This uses past simple tense ("was liked"), which is correct for reported speech when the reporting verb "told" is in the past tense.
- you are liked by the whole class: Here, "you" assumes the listener's perspective, which doesn't reflect the third-person perspective of "he" from the original sentence context.
- he is liked by the whole class: The present tense "is liked" isn't shifted back to past tense, making this option incorrect.
- you were liked by the whole class: Similar to option 2, "you" doesn't fit the pronoun perspective required in this context.
From this analysis, the best sentence completion is: he was liked by the whole class as it correctly applies tense backshifting and maintains consistent pronoun use.
