1. 53кг 800г + 9кг 760г = 63кг 560г
    53800г + 9760г = 63560г
2. 2км 700м - 1км 800м = 0,9км
    2700м -1800м = 900м
3. 18т 5ц + 3т 6ц = 22т 1ц
    18500ц + 3600ц + 22100ц
4. 4м 23см -1м 80см = 2м 43см
    423см -180см =243см

Английский язык 7 класс 6. The British children asked us more questions. Read the answers and guess what the questions were. 1. The ecological situation in Russia is not very safe. Pollution in some industrial towns is high. Some parts of western Russia were badly influenced by radiation from Chernobyl in 1986. In many places wildlife is in danger. Anyhow, more and more people are beginning to realize that a clean environment is extremely important. Ecological education has found its way into schools. We all hope that the situ- ation will soon become better. 2. Perhaps the greatest love of Russians is for tea. It's drunk without milk and is often served with homemade varenye (jam), baranki (circles of dry pastry') and pirozhki (baked pastry with some filling). Russian-style tea is a special ceremony when people sit around a table with a samovar |' sæmava:] (tea-urn) placed in the middle and drink hot strong tea with a slice of lemon either from cups or from glasses in glassholders. 3. Usually tourists buy traditional Russian sou- venirs such as Matryoshka dolls, beautifully paint- ed mugs, plates and spoons from the village of Khokhloma and Palekh boxes. Richer people buy amber, furs, art books and caviar. Some tourists are more interested in badges, T-shirts and Russian fur hats (ushankas). 4. The main dishes of the traditional menu are blini (pancakes) with honey, caviar or sour cream, different soups (like shchi and borshch), pirozhki, pelmyeni (boiled pastry with a meat filling) served with mustard, but- ter, vinegar or sour cream. Russian people eat brown bread with near- ly every meal. 5. Many Russians are religious people. The main church is the Russian Orthodox Church. It has survived the hard times and now people speak about a rebirth of religion in the country. New church- es and cathedrals are built every year, old ones are restored. But not all people in Russia belong to the Orthodox Church. There are other religions too and there are a lot of people who are non-believers.
