Представьте, что вы получили письмо от мэри, которая пишет: last week we had a very difficult test in maths. i am afraid my mark will be very bad because i couldn’t answer many questions… how often do you have tests at school? what marks do you usually get? can you use your mobile phone at tests? напишите мэри ответ, ответьте на все вопросы, которые ее интересуют. не забудьте о правилах оформления письма. в письме должно быть от 60 до 90 слов.
