СРОЧНО!!!!ОЧЕНЬ НУЖНО !!!
Нужно написать лист про любой праздник ( день рождения , новой год и т.д) или же про семейный праздник как его отметили
Это пример как нужно что бы выглядело:

Dear Livia,
I'm so happy to hear from you. We definitely have a lot of holidays and celebrations in the US, but I think the most important one is the 4th of July. It's the anniversary of when the Declaration of Independence was signed in 1776.
Some of the things that you can do on The Fourth include going to a parade, having a cookout or picnic and watching a fireworks display. Where I live, a day before the holiday itself, there is a fireworks display which is the largest in the country and is called Red, White and Boom. You wouldn't believe the kinds of fireworks you can see there! On The Fourth, we have a cookout that lasts the whole day. Friends and family come over and we play games and eat a lot of food, especially corn on the cob and watermelon.
I like this holiday better than others because it's a great chance to relax and get together with people you don't see very often. It's a very casual holiday, and you don't have to dress up; you just dress comfortably and have fun.
I hope this will be of help to you in your project. Would you like me to send you some pictures, too? It would be no problem.
Take care,
Heather
