8A Chapter 4 Writing---WorksheetTask One: Read the letter below and fill in the blanks.Dear Gracie,I have just moved to Beijing from Boston for two months, and I really want to tell you how different between the two cities.Although the names of both cities begin with the letter B, Boston and Beijing are very different places. First, Beijing is special because it is the capital of China. Boston is just an ordinary（普通的）city in America. The climate（气候）of Beijing is much dryer than that of Boston. It seldom rains or snows there. Boston sometimes rains heavily, especially in the spring, and has lots of snowstorms（暴风雪）every year. Beijing is a city with several thousand years of history, while Boston is only a few hundred years old, so it is much younger than Beijing. Everywhere you go in Beijing feels very crowded, but there are far fewer people on the streets in Boston. Therefore，the traffic in Beijing is a lot worse and the air is far more polluted than that in Bo ston. It is easier to get sick there. Boston’s air is clean and clear most of the time, which makes it a very healthy place to live. However, people in Beijing are trying their best to make the environment better.I love to live in Beijing, because food here is more delicious and people are more friendly. I also miss Boston, because the air there is much cleaner.Can you tell me something about your city—it is Shenzhen, right? I’m looking forward to seeing you soon.Best regardsSimonFill in the blanks:1.Beijing is the _____________ of China.2.Beijing __________ rains or snows, but Boston sometimes rains _____________.
