London is very beautiful city and the capital of the United Kingdom. And I would like to discuss the most beautiful places in London, which I like most. The first one is the London eye. You can see up to 25 miles in each direction with views over some of the world's most famous sights, including St Paul's, the Palace of Westminster and Windsor Castle. Anothe sightseeing is Big Ben. The name "Big Ben" is generally known to describe the clock tower as a whole. However, "Big Ben" is actually the principal bell within the tower. And one more sightseeing is Tower of London. At the Tower Bridge Exhibition you can enjoy views from the high-level Walkways and learn about the history of the Bridge and how it was built.
Twenty years ago families used to have 2-3 generations. Frequently fellows didn't know their grandparents. But according to the latest researches families will consist of 3 or even 4 generations. Here are some predictions: 1) People will live longer and, as a consequence, (will) know even their grand grandparents 2) Families won't have a lot of children. As a result, children won't have cousins 3) Children will grow isolated from other ones, and that will make them selfish 4) Couples will divorce and marry, so many children will get stepmother or stepfather 5) There will be a lot of children, which marry and return to theirs families 6) There will be more single-parent families
