I think about a man who is riding a bike. I wander, where's he riding? Also I think about all these people on this wide street, they're going somewhere too. You can see these gorgeous buildings, different people have been living there for a long time. Of course, there are different shops with many good things on the ground floor of these buildings.
May be there is a double decker bus, actually, I can't see it very well. And of course
I can see a very high and beautiful clock tower.
This street is lovely with lots of people and shops, I'd like to be there.
Объяснение:
I usually have four meals a day. They are breakfast, lunch, dinner and supper.
Most of my classmates have a snack rather than a meal in the morning. But for me breakfast is the most important meal, because it gives me energy for the day. I usually have breakfast at 8 o'clock before going to school. I usually have porridge with fruits or eggs and bread with butter or bacon. For breakfast, I always drink black coffee with no sugar in it.I have lunch at about 1 p.m. At first, I drink a glass of orange juice, and then I eat vegetable salad with some meat in it. Sometimes I have pies with mushrooms, potatoes or jam instead of salad. Then I drink tea.
My dinner is at four or five o'clock. It consists of soup for starter, meat or fish with vegetables for the main course and dessert, which can be various: chocolate sweets, jelly, ice-cream or cookies.
The last meal of my day is supper, which is at eight or nine o'clock. My mother usually cooks fried fish and potatoes, chicken or omelette. We also have a salad every evening. After supper, I drink tea or cocoa with biscuits. Before going to bed, I drink a glass of warm milk with honey. It helps me sleep well and feel healthy next morning.
