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.

We all study in the classroom in the school, but what are classrooms like in different countries?

In China, children have a fixed (固定的) classroom. In a classroom, you can see desks and chairs in lines. There are usually about 40 or more students in every class. They always face the blackboard.

In the UK, most classrooms are similar. There are usually about 30 students in every class. Usually, two children have a long desk.

In the US, classrooms usually have single (单人的) desks for every student. There are about 15-25 students in a class. The US children don't have a fixed classroom. They always go to different classrooms when the classes are different.

Students in Japan have a fixed classroom and they have single desks, too. At the back of the classroom, there are places for students' clothes. At the gate of the school building, there are places for their shoes.

①Some people think that we aren't really able to form memories before our fourth or fifth birthdays. But scientists say this is untrue. They think we form memories at a very young age. However, the memories seem to change as we get older.

②Researchers in Newfoundland, Canada, interviewed 140 children aged between 4 and 13. First, they asked the children to describe their earliest memory and tell their ages. Next, they asked their parents to make sure the event actually happened. All the answers were recorded. The researchers waited for two years before they went back to the children and asked them again," What's your earliest memory?"

③Nearly all the children were aged between 4 and 7 in the first interview. They said something very different in the second interview. However, many of the children who were between 10 and 13 at the first interview described exactly the same memory in the second interview. This seems to suggest that our memories change in the early years, but at around the age of ten, they make the things that we remember fixed.

④The researchers are now looking into why children remember certain events and not others. We sometimes think that most first or early memories are about very stressful things that happened to us as children, because bad things stand out in our minds. But in this study, stressful things were only a small part of what the children said they remembered. More often, children's early memories were happy ones. The researchers are trying to work out the reasons. We can surely look forward to more fascinating discoveries about memories in the near future.

My parents and I take a trip to the mountain on the Double Ninth Festival（重阳节）each year. We always g{#blank#}1{#/blank#} up very early in the morning. The weather is usually cool at this time of year, so we always spend our whole day there. As we walk t{#blank#}2{#/blank#} the forest, the wind b{#blank#}3{#/blank#} gently on our faces. The mountain roads are c{#blank#}4{#/blank#} by dry yellow leaves. Everything is so beautiful! We always have p{#blank#}5{#/blank#} at the top of the mountain.

I am John. My family and I move to a new house. In my room, the books are always in the bookcase. My computer games are always there, too. My balls are always in the box under the bed. My schoolbag is always on the sofa. I clean my room three times a week. 

I have a brother. His name is Alan. His room is always in a mess. His books are everywhere. They are on the bed, on the sofa and under the desk. His computer games are on the bed. His jacket is on the sofa. Where is his schoolbag? Oh, it's under the bed. Our parents say, "Alan, come in. Look at your room. You must learn to be a tidy boy. "
