помогите сделать тест,пожалуйста(английский)

Dear Ann

13 ARE You free to come to dinner here on Saturday next at 8.00? 14 My brother Paul IS COMING and BRINGING a friend of his called Tom Edwards. 15 You HAVEN'T MET Tom but I THINK you WILL LIKE him. 16 He is an assistant stage manager at the Gate Theatre and WILL BE ABLE to tell you about the actors. 17 Paul says Tom RECEIVES hardly any salary and DOES'NT often GET enough to eat, so he ASKED me to have roast beef and Yorkshire pudding for dinner, with apple dumpling to follow. 18 He WILL probably RING up between now and Saturday, to say that it IS a good idea to start with a substantial soup, such as ox-tail!

19 I KNOW you DON'T usually EAT heavy three-course meals of this type, but I HOPE the conversation WON'T BE so heavy. Anyway, come if you ARE ABLE

Love
Mary

Надежда Егорова - умничка!
Юленьке нужно подучиться (вместе с Сергеем Петровым, увы: -)

yulia ostrivna молодец, нашла ошибку.

у всех одна ошибка! вместо to be able to....he can(could) tell you about the actors. и в конце, соответственно, тоже anyway. come if you can
it sounds more natural.
