Инфинитив для выражения цели

Мы используем infinitive для выражения некоторой цели.

Это может быть цель действия:
"Why are you going out?" "To post a letter."
A friend of mine phoned to suggest an interesting job in a club.
We shouted to warn everybody of the danger.
Или, мы говорим, почему что-то существует:
This wall is to keep people out of the garden.
There are many computers in the office to register clients.
Мы также употребляем инфинитив, чтобы сказать, что может быть сделано или должно быть сделано:
You always can find a camping to stay for a few days.
Would you like something to eat?
Have you got much work to do?
I get lonely if there's nobody to talk to.
I need something to open this bottle with.
Мы часто употребляем слова money, time, chance, opportunity, energy, courage перед инфинитивом цели:
They gave us some money to buy some food.
Do you have any opportunity to speak Spanish?
I need a few days to complete the article.
Мы используем in order и so as перед инфинитивом для пояснения:

We immediately started to discuss the problem so as to solve it as soon as possible.
In order to start your own business, you need to have a good start-up project.

Иногда мы должны использовать so that вместо инфинитива.
В этом случае мы употребляем present simple или модальные глаголы. В частности, мы употребляем so that если исполнитель цели отличается от подлежащего в главном предложении:

He works hard so that his family has everything they need.

С come и go, мы можем использовать инфинтив с глаголом в любом настоящем или прошедшем времени или с герундием:
I'm just coming to help.
We went to talk to a lawyer.
Are you going to see our mother soon?
