We u the prent conditional ten in English to speculate about prent or future situations that could theoretically happen. This ten is ud when the action is either impossible (unreal) or when we do not think that the action will happen.
He would sign it. (But he can't. It is not possible.)
I would travel by plane. (If I wanted to go on holiday. But I do not want to go.)
In the first person singular and plural should instead of would is also possible. But it is not very common in modern English.
I should/would be really glad. (If you could help me). We should/would nd the fax. (But we do not know how to do it).
Should, however, can also express a recommendation or advice. In this respect, it is similar to ought to.

He should drive carefully. He ought to drive carefully. (Or he will crash one day.)
You should speak loudly. You ought to speak loudly. (I can't hear you.)hape

She might come with us tomorrow. (We hope that it is possible, but we are not sure.)
Could is also the past form of can and express possibility, ability or permission in the past. Possibility: She could travel in our car. (It was possible becau we had a free at for her.) Ability: She could play again in the last match. (She was able to play becau she was not ill anymore.)
