    Back in the twentieth century, robots seemed to have a big future, at least in the movies. Like the robots servants in the Star War movies. It looked as if one day robots would do all the boring or dangerous jobs while the humans sat around doing something more interesting. But people were also frightened that robots might become the bosses, not the servants.

    Has it happened? You're still unlikely to see a robot walking around your town but that doesn't mean they don't exist. Robots are used in car making, and in areas which are dangerous for humans, in bomb producing and deep-sea discovering, for example. We employ robots instead of doing the job ourselves. According to the report, there are 750,000 working robots in the world today.

    These working robots definitely look like machines but many scientists are now trying to make robots look more similar to humans. So what will robots be able to do by the year 2030? There are already plans to use robots in hospitals and old people's homes. Robot nurses will remind patients to take their medicine or tell a doctor if the patient needs attention. But many people are worried about the idea of robots looking after the old, the sick and the very young, separating them from important human contact. It may also create unemployment. It is really possible that robots will be used for many jobs in areas.

    But can we be sure that the next generation robots will always follow human orders? Or even destroy them? Or will we be able to create robots with emotions? Only the future will tell.

    When I was a little child, I dreamed to be a rich man who could fly around the world and take the first class (头等舱) on the plane. After I grew up, when I first took the first class, I felt like part of the rich group. I was filled with a sense of pride when sitting with those important people.

    Once I was on the plane, I noticed that the stewardess (空姐) was working all the time to make sure that first class passengers felt comfortable. I thought she must love her job very much, because she gave everyone a big smile. When the stewardess walked past my seat, I looked up at her and said, "Thank you and I hope you have a great night." She stopped with a look of surprise on her face, and said, "Excuse me?" I said my words again. It seemed that I asked a question that she did not know how to answer.

    A little later, when I was getting off the plane, the stewardess said to me, "Thank you very much, sir." Then she said, "You are the only passenger who has thanked me or said anything nice to me all night." The pride of being part of rich group disappeared as soon as I heard these words. Then I came to understand that taking the first class didn't mean you were a real "first class" person.

    Canada is the second-largest country in the world, with almost 10 million square kilometres of landmass. Due to (由于) its size, it is divided into four different regions(地区).

    The Atlantic Provinces

    Fishing is the old industry in this region. Agricultural crops, such as fruit and potatoes, and forests, which produce paper and lumber(木材), form part of the industry. Traditionally depending on fishing and farming, they are developing other natural resources, such as oil and copper.

    Central Canada

    Ontario and Quebec form the industrial and manufacturing (制造业的) heart of Canada. They produce three quarters of Canada's goods. More than half of Canada's population lives in the cities in the southern part of Ontario and Quebec. Most of the people living in Quebec speak French.

    The West Coast

    The British Columbia Coast is Canada's western continental coastline (海 岸 线 ). Europeans settled (定 居 ) in British Columbia in the early 1800s. The railroad built by the government in the late 1800s made moving much easier. Thousands of Chinese came to British Columbia during this period to work on the railroad. British Columbia has the most valuable forest industry in Canada.

Salmon (鲑鱼) fishing is not only a popular sport, but also an important part of the industry. Pacific salmon are exported (出口) all over the world.

    The North

    The Yukon and the Northwest Territories (领土) cover a third of Canada. This huge region has a very small population. Most of the people are natives. There are several native languages, which are equal (平等的) in status (地位) to English and French. During the Gold Rush at the end of the 1800s, thousands of miners (矿工) came to make their fortune (财富). Mining is still an important industry in this region.
