Os verbos modais em inglês são auxiliares que adicionam sentidos... Show more






Os verbos modais modificam o significado do verbo principal para expressar diferentes intenções na comunicação. Você vai perceber que eles são super úteis para tornar seu inglês mais natural!
'Can' é um dos modais mais usados no dia a dia. Você pode usá-lo para expressar habilidade (I can speak English), permissão (Can I go to the cinema?), fazer pedidos (Can you wait a moment?) ou ofertas (I can lend you my car).
'Could' é a forma passada de 'can', mas também serve para tornar seu inglês mais educado. Use-o para falar de habilidades no passado (I could speak English when I was five), fazer pedidos mais educados (Could you help me?) ou sugerir algo de forma mais gentil.
💡 Dica: Usar 'could' em vez de 'can' em pedidos torna sua fala mais educada e aumenta suas chances de receber uma resposta positiva!

'May' é um modal mais formal que 'can'. Você vai usá-lo principalmente para expressar possibilidade (It may rain today) ou permissão formal (May I go to the cinema?).
'Might' é semelhante ao 'may', mas indica uma possibilidade menor. Quando você diz "It might rain" está sugerindo que a chance é menor do que se dissesse "It may rain". Use-o quando algo é possível, mas não muito provável.
'Must' é o modal que expressa obrigação forte ou necessidade. Quando você diz "I must study" está indicando algo que é absolutamente necessário fazer. Também pode indicar alta probabilidade (You must be tired after that long trip).
'Must not' e 'May not' são usados para proibições, mas com intensidades diferentes. 'Must not' é mais enérgico e definitivo , enquanto 'May not' soa um pouco menos severo.
💡 Lembre-se: 'Must' para obrigações é como um comando interno (algo que você sabe que precisa fazer), enquanto 'have to' (que não é um modal puro) geralmente indica uma obrigação externa!

'Need not' (ou 'needn't') é perfeito para expressar quando algo não é necessário. Imagine economizar tempo dizendo "I needn't go to the supermarket" em vez de "I don't need to go to the supermarket"!
'Ought to' é muito parecido com 'should', mas soa mais rigoroso. Use-o para dar conselhos fortes ou falar de obrigações morais. Por exemplo: "You ought to drive carefully in bad weather" é um conselho mais enfático que usar 'should'.
'Shall' geralmente substitui 'will' na primeira pessoa (I, we), especialmente em inglês britânico. Também é muito usado para fazer sugestões em perguntas, como "Shall I carry your bag?". Fica super educado!
'Should' é o modal que expressa recomendação ou obrigação moral menos intensa que 'must'. É perfeito para dar conselhos ("You should eat more vegetables") ou falar de expectativas sobre como as coisas deveriam ser.
💡 Quando quiser fazer uma oferta educada para ajudar alguém, "Shall I...?" soa muito mais prestativo e formal que "Can I...?"

'Will' não serve apenas para formar o futuro! Como modal, você pode usá-lo para expressar desejos ou dar ordens ("Will you please shut the door?"), fazer promessas ("I will call you tomorrow") ou tomar decisões espontâneas ("I will help you with that").
'Would' é a forma passada de 'will', mas também torna seus pedidos muito mais educados. Em vez de dizer "Will you help me?", diga "Would you help me?" e note como soa melhor! Também serve para falar de hábitos no passado ("He would always bring me flowers on Fridays").
Os verbos modais podem ter funções semelhantes, mas com níveis diferentes de formalidade ou intensidade. Por exemplo, para pedir permissão, 'may' é mais formal que 'could', que por sua vez é mais formal que 'can'.
Para expressar possibilidade, você tem uma escala de probabilidade: 'might' (menos provável), 'may', 'could' e 'can' (mais provável). Já para obrigações, 'must' é mais forte que 'ought to', que é mais forte que 'should'.
💡 Nas entrevistas de emprego ou situações formais, substitua 'can' por 'could' ou 'may' para soar mais profissional e educado!

Agora é hora de testar o que você aprendeu sobre os verbos modais! Tente completar as frases abaixo com o modal mais adequado para cada situação:
Para expressar habilidade presente, você usaria: "I can speak three languages." Isso mostra sua capacidade atual de falar idiomas.
Para dar um conselho sobre o tempo: "You should take an umbrella, it might rain." O 'should' é perfeito para recomendações.
Em um pedido educado, experimente: "Could I borrow your pen, please?" Isso soa mais gentil que simplesmente usar 'can'.
Para indicar proibição clara: "You must not eat in the library." Isso deixa claro que a ação é proibida.
Para fazer uma previsão sobre o tempo: "I think it will be sunny tomorrow." O 'will' é ideal para previsões futuras.
💡 Pratique usando diferentes modais para a mesma situação e note como o tom e a intensidade da mensagem mudam! Isso vai ajudar você a escolher o modal perfeito em cada contexto.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
