Robots have intrigued humans and captured our imaginations for centuries. As early as the 8th century B.C., Homer, in his epic poem Illiad, described "handmaids of god resembling living young damsels." Science fiction literature and motion pictures also have pictured mobile devices, human- in form, encased in metal, and able to do those everyday tasks from which many of us would to be freed.
Despite our long fascination with robots, the first U.S. patent for an industrial robot was issued less than 40 years ago to George C. Devol.. In 1958, Joseph F. Engelberger, a science-fiction enthusiast, developed the first programmable manipulator, or robot. Since then, robots have become indispensable to the industry, to medicine, and to the United States space program. And while today's robots may not look or perform as fantasally as those featured in literature or movies, they are the fulfillment of dozens of science fiction visions.

Nowadays, more and more people want to live in the city because of its advantages. However, living in a city has several drawbacks. Firstly, there are traffic jams. On the roads, especially rush hours, many vehicles are moving on the same road and it caused traffic jams. The increase in population and numbers of owner vehicles have caused traffic accidents every day. Public transport is uncomfortable and inefficient for most people. Secondly, air pollution has negative effects on people's health, animals, vegetation and buildings.

Life in modern cities truly causes a lot of nuisances. In the first place, citizens have to deal with traffic congestion every day. This problem is even worse in the rush hour when so many people run out to work and are stuck on the streets for hours. Next, the high cost of living is also a serious issue in the city, especially in metropolitan cities. More and more people find it difficult to live on their modest salaries when prices are going up all the time. Financial pressure makes city dwellers become constantly stressed and tired. Finally, the polluted air caused by exhaust emissions from millions of vehicles, construction dust and the lack of green trees negatively affects residents’ health. Many people suffer from respiratory problems such as cough, sore throat or asthma. Indeed, city life brings a number of difficulties as well as challenges to its citizens.
Dear Dad and Mom,
I arrived in Thai Land late in the morning, about at twelve o'clock. When I came, the weather was fine and the day was beautiful. I enjoyed the cool and fresh mild air although it was nearly midday.
Uncle Nam met me at the bus station and took me home on his motorcycle. I visited many beautiful places in Thai Land such as the Patong Beach, the Wat Phrathat Doi Suthep Pagoda and the Phi Phi Island.
Yesterday Uncle Nam took me to the Thi Lo Su and Erawan Waterfalls. The waterfalls are very beautiful and impressive. I've never seen such beautiful and fascinating sights.This morning, we went to visit some village . They live in small cottages. They were very friendly and they always invited us to stay with their for meals
For meals, we eat a lot of special food and tasty fruit such as Nuea daet diao kaphrao thot , Khao man kai , ...
The atmosphere here is very lovely and peaceful. I feel relaxed myself with the nature. I'm enjoying myself very much. I bought some fruits and some souvenirs. I also had some photos of places I visited to show you about my trip. I'm planning to go home next Thursday. Uncle and Aunt Nam asked me to give you their regards.
Stop for now. See you on Thursday.
Your daughter,
