Demonstrative pronouns are easy to remember because they are often accompanied by a demonstration: when we speak, we use our hands to show them. For the demonstrative pronouns this, that, these, and those, we point with our finger or gesture with our hands in the general direction of the thing we’re talking about. For the demonstrative pronounsnone and neither, we often make a gesture implying rejection or emptiness.This: singular and close to the speakerI’ll have this little chocolate cake.That: singular and relatively far away from the speakerI’ll also have that strawberry cake, the one on the bottom shelf.These: plural and close to the speakerI’ll have three of these walnut biscuits.Those: plural and relatively far away from the speakerAre those butter tarts?

January 1 is one of the most light and joyful holidays in the world, it’s New Year's Day. This year, I spent it in the village with my parents and my grandmother , who lives near Volgograd. I have many friends in this village, because I often go there for my holidays. 
Our parents allowed us to celebrate New Year in one of our neighbors’ house. We set a great holiday table with traditional Russian dishes which were prepared by my grandmother and our girls, they prepared a lot of different things: goose with apples, salads and my grandmother's favorite hot pies.
 I was Santa Claus during this holiday and I gave everybody the gifts that we had prepared for each other.

1 января-это один из самых светлых и радостный праздников в мире, это Новый год. В этом году я провел его в деревне с моими родителями и моей бабушкой , которая живет недалеко от Волгограда. У меня много друзей в этой деревне, потому что я часто езжу туда на каникулы. 
Наши родители позволили нам встретить Новый год в доме одного из наших соседей. Мы накрыли большой праздничный стол с традиционными русскими блюдами, которые готовили мои бабушка и наши девушки, они приготовили много разных вещей: гусь с яблоками, салаты и любимые горячие пирожки моей бабушки.
Я был Дедом Морозом в этот праздник, и я дарил всем подарки, которые мы приготовили друг для друга.
