Essa é uma dúvida que assola muita gente. Quando devo usar IN? Quando devo usar ON? E quando devo usar AT? Qual está certo? IN Monday, ON Monday ou AT Monday?
Nesse artigo vamos cobrir as diferenças do IN, ON e AT para falar de TEMPO:
A regra geral para te orientar é: Use IN é para situações mais gerais, ON para um pouco mais específicas, e AT para super específicas! Veja:
IN:
Use IN com:
– meses do ano: This product will be launched in October.
– anos: Our company was founded in 1999.
– periodos do ano: We’ll revise this in the second semester.
– estações: The project will start in summer.
– partes do dia (exceto noite): We had a meeting in the morning.
– para falar de um periodo de tempo, com sentido de “daqui a”, “dentro de”: We believe this software will be developed in 4 months.
Mais exemplos:
– The contract ends in August.
– She created this product in 2011.
– They’ve decided to raise the prices in the third quarter.
– They only make this product in winter.
– Shall we talk about this in the afternoon?
– He completed the task in 4 hours.
ON:
Use ON com:
– dias da semana: We always meet on Fridays.
– datas (dias / dia e mês / dia, mês e ano): They are coming on the 22nd.
Mais exemplos:
– She has English classes on Wednesdays.
– He will visit us on Tuesday.
– I’ll be flying on Nov 3rd.
– The contract was signed on Jun 7th, 2017.
AT:
Use AT com:
– horas: The call starts at 4 pm.
– night: I don’t eat much at night.
– datas comemorativas: We always have a big celebration at Christmas.
Mais exemplos:
– I usually wake up at 6.30 am.
– They always travel at Easter.
OBS 1: Weekend:
Inglês americano, usa-se ON / inglês britânico, usa-se AT:
Our office is closed on weekends. (US)
Our office is closet at weekends. (UK)
OBS 2: Quando houver: THIS, THAT, SOME, EACH, LAST, NEXT, PREVIOUS, EVERY, ANY, ALL, não precisa de preposição:
– We’ll discuss this topic next Friday. (errado: “on next Friday”)
– I talked to her last Monday. (errado: “on last Monday”)
