MY FLAT

Read the text and describe your own flat.

I live in a new block of flats in Pushkin street. In front of the house there is a children’s playground. Our flat is on the third floor. It’s very comfortable. We have all modern conveniences, such as central heating, electricity, cold and hot running water and a telephone. There are three rooms in our flat: a living room and two bedrooms. We also have a kitchen, a bathroom, a small hall and a balcony.

Our living room is the largest in the flat. Against the wall you can see a nice sideboard. In the corner there is a TV set. In the opposite corner there is a sofa and two armchairs. The piano is on the right. There are two pictures above the piano. There is a nice carpet on the floor among the room.

Our bedrooms are very nice. The parents’ bedroom is larger than the children’s. There are two beds, a bedside table, some chairs and a wardrobe in it. There is a lovely carpet on the floor between the beds.

The children’s bedroom is just across the corridor on the right. Here you can see two sofa-beds where my sister and I sleep at night and have a rest in the day-time. There is also a desk, two chairs and some bookshelves here. We use our bedroom as a study where we do our homework. In the corner of the room there is a small table with a tape-recorder on it.

Our kitchen is rather large. There is a stove, four stools, a refrigerator and a cupboard in which we keeps cups, plates and all our dishes.

The entrance hall is small. There is a hall stand and a mirror on the wall. A telephone is on a special table under the mirror.

We are happy to have such a nice flat.

Полезное ископаемое - природное минеральное образование, пригодное для использования в промышленности в естественном виде или после предварительной обработки (переработки) путем дробления, сортировки, обогащения для извлечения ценных металлов или минералов.

Руда – минеральное сырье, содержащее ценные полезные компоненты (металлы, их соединения, минералы) в количестве, достаточном для промышленного извлечения при современном состоянии экономики, техники и технологии.

Качество минерального сырья - совокупность свойств, определяющих способность удовлетворять конкретные требования потребителя. Свойства, обуславливающие качество минерального сырья, характеризуются с трех позиций: свойства, обуславливающие соответствие назначению, технологичность (возможности и особенности обогащения и извлечения полезных компонентов или минералов) и сохраняемость.
