Os verbos must e need são sinônimos e exprimem que algo é necessário ou exigido.
É preciso que se entenda um pouco mais sobre esses verbos para escolher a opção correta.
Must ou need?
- O verbo must é o que se chama de verbo modal, modifica o verbo que vier depois dele, que virá no infinitivo sem "to".
- Must exprime uma obrigação ou uma enfática sugestão.
- Diferente do que ocorre em português, em que "precisar" pode exprimir uma obrigação ou uma necessidade, o verbo "need", cuja tradução é precisar, expressa apenas uma necessidade.
- Uma diferença fundamental entre must e need é que "need" deve ser conjugado de acordo com a pessoa ( I, you, he/she/it, we, you, they) da frase. Além disso, quando aparece outro verbo depois do "need" ele vem no infinitivo, ou seja, com o "to".
