Perfect Tense and Technology Vocabulary
The perfect tense in Spanish works similarly to English - it's all about what you "have done". You use forms of "haber" (he, has, ha, hemos, habéis, han) plus a past participle. Most past participles are dead easy: just add -ado to -ar verbs (visitado) or -ido to -er/-ir verbs (decidido, comido).
Watch out for those irregular past participles though - they're proper important! Key ones include: abierto (opened), dicho (said), escrito (written), hecho (done), and visto (seen). These pop up constantly in exams, so get them memorised.
When discussing technology, para + infinitive means "in order to" - brilliant for explaining why you use devices. "Uso Instagram para contactar con mis amigos" shows purpose clearly. Se puede + infinitive means "you can" - perfect for describing what technology allows us to do.
Quick Tip: Look for opinion markers like "lo bueno" (the good thing), "las ventajas" (advantages), and "demasiado" (too much) - they're your clues for positive or negative viewpoints!
