Unless, As и As long as



Мы используем союз unless в значении "если только не".

За unless следует придаточное предложение. Вот некоторые примеры:

  • Unless it rains, we'll go for a picnic by the river tomorrow.
  • There are no buses to the beach. Unless you have a car, it's difficult to get there.
  • "Shall I tell Liz what happened?" "Not unless she asks you."
  • Sally hates complaining. She wouldn't complain about something unless it was really bad.
  • We can go by car to the center - unless you would prefer to walk.
  • Вместо unless часто можно сказать if ... not:
  • If we don't leave now, we'll be late.

  • Мы употребляем as в значении "во время того, как":

  • We all looked at the sky as the rocket were flew above us.
  • I watched her as she opened the letter.
  • As I walked along the street, I was thinking how to make workaround in the program.
  • Can you turn off the light as you go out, please?
  • Мы также используем as чтобы сказать, что что-то произошло во время того, как мы делали что-то другое. В этом случае мы используем Past Continuous:
  • Margo slipped as she was trying to climb the stairs.
  • We met Paul as we were leaving the hotel.
  • Иногда мы говорим just as что означает "именно в этот момент":
  • Just as I sat down, the phone rang.
  • I had to leave just as the conversation was getting interesting.
  • Мы также используем as когда две вещи длительное время происходят вместе:
  • As the time went on, the weather got worse.
  • I began to enjoy the job more as I got used to it.
  • Сравните as и when:
Мы употребляем as только если две вещи происходят одновременно.

Мы употребляем when если одна вещь происходит после другой.

  • As также может иметь значение "потому что":

  • As it was a public holiday last Thursday, most of the shops were shut.
  • As we have plenty of time before our flight, let's go and have a coffee.

  • Сравните as и when:

    As long as, so long as, providing (that), provided (that), все эти выражения означают "если" или "при условии, что". Выражения с providing (that) и provided (that) звучат более официально.

  • Travelling by car is convenient provided (providing) that you have somewhere to park.

  • Providing the weather is good, we're going to have a picnic.
