Question

в чем отличие в использовании глаголов must и should

Answer 1

must - должен, обязан

You must stay in bed - ты должен оставаться в постели -настоятельный совет 

You must do it - ты должен это сделать - настоятельный совет другого человека

I must do it today - я должен сделать это сегодня - когда человек сам нонимает, что он должен сделать

You mustn't cross the road ты не должен переходить дорогу -категорически запрещается

should - "должен", "следует", "следовало бы" - более мягкое значение

You should stay in bed  - тебе следует оставать в постели - совет

 

для сравнения:

ты не должен есть мороженое - если mustn't - то это категорическое запрещение

                                                                 если shouldn't - это просто совет, рекомендация

Answer 2

Difference Between "Must" and "Should"

When it comes to the usage of the verbs "must" and "should," there are distinct differences in their implications and contexts.

Must: - The use of "must" implies a strong necessity or obligation. It indicates that something is required or essential. - For example, "You must write your answers with a pen" conveys a sense of obligation or necessity [[1]](https://englishprime.ua/v-chem-raznitsa-mezhdu-glagolami-must-i-have-to/).

Should: - On the other hand, "should" suggests a recommendation or advice. It indicates that something is desirable or advisable, but not mandatory. - For instance, "This is a fantastic film! You should watch it!" conveys a suggestion or recommendation rather than a strict obligation [[1]](https://englishprime.ua/v-chem-raznitsa-mezhdu-glagolami-must-i-have-to/).

In summary, while "must" conveys a sense of strong necessity or obligation, "should" is more about recommendation or advice, indicating something that is desirable but not mandatory.
