School is out! Adverb placement and translation of the perfect tense

The SSCs [qu], [ch] and [th] are consonant clusters pronounced as in 'question', 'chercher' and 'th'. Adverbs of time (saying exactly when), and of place, normally come at the beginning of a sentence: hier, j'ai travaillé. Other adverbs, including adverbs of time saying generally when, come after the conjugated verb form: j'ai enfin mangé. The perfect tense can be translated into both the simple past and the present perfect in English. Sentences with adverbs of a specific time use the simple past in English.
