Hello, everyone! My name is Sue. I live in Canada. Canada is a large country with a population of about 36 million. I live in a small mountain town called Fairmont. I have lived here since I was three. Fewer than 600 people live here. The small town is surrounded by trees. The air is clean and fresh. People live close to nature and try to protect it. They are careful with garbage and discourage cutting trees. The town is really like one big family. The local people often help each other and have fun together. But sometimes it is hard to see friends because they live so far away.
Hi, I'm Li Ming. I live in Beijing, the capital of China. My city has a long history and many places of interest. We have big shopping centers and huge markets. Our public transportation is excellent, too. Buses, taxis, and subways can take my friends and me to any part of the city. We can play sports, see Beijing operas, go to movie theaters, and eat delicious food. There are many fine places such as Beihai Park and Tian'anmen Square where we can meet with friends to dance or listen to music. I love my city of Beijing because I have so many friends here and we have so many interesting places to visit together.But now the large population in Beijing has caused some problems.

Language points
1. I live in a small mountain town called Fairmont.
我居住在一个叫Fairmont 的小山城。
called Fairmont过去分词短语放在名词后作后置定语，这里called可改为named/with the name of ...。
e.g. The boy called/named/with the name of Li Lei is my brother.
名叫李雷的那个男孩是我的弟弟。
2. interest意为“吸引力，趣味”，不可数名词。
a place of interest一处名胜 places of interest 许多名胜。
e.g. There are many places of interest in our city. 我们城市有许多名胜。
①“So + be/情态动词/助动词+主语”该结构主要用来说明前面所说的情况也同样适用于后面的人或物，[意为“……也一样”]。该结构中的助动词 do 根据前文的情况也可换成 is, am, are, was, were, does, did, can, could 等。
如: He passed the exam, and so did I.
=He passed the exam, and I passed the exam, too.
但是如果前面所述情况为否定式，则用neither, nor引出倒装句(此时不能用so)。
如: He couldn’t do it, and neither could she. 他做不了这事，她也做不了。
He never comes late. Nor do I. 他从不迟到，我也从不迟到。
※ So do I 与 So I do
②“So +主语+ be/情态动词/助动词”该结构主要用于加强语气，其意为“的确如此、确实如此” ，表示后者赞同前者的话或意见，只是进一步强调并重复前句所述的内容。前后句的主语指的是同一个人或物。该结构中的助动词 do 根据前文的情况也可换成 is, am, are, was, were, does, did, can, could 等。
