The first blazes started in August. It is common for fires to happen in     3     and rural areas at this time of year in the US. It is known as "fire season" and happens between June and September. However, this year's wildfires are some of the worst on     4    . Three of the blazes in California are now among the biggest in the state's history. Once they started, strong winds caused the flames to spread quickly.

There are several causes for the fires. Some were started     5     by people, and others were caused by lightning strikes or electrical equipment. Yet experts say the fires are particularly bad this year because of climate change. Climate change is the long-term changes in world weather patterns,     6     rising temperatures. In recent years, California has experienced drought (a long period of time without rain) and very hot temperatures. This month, heatwave in California saw temperatures     7     49℃ in Los Angeles county. This hot, dry weather creates ideal conditions for wildfires to spread. Another cause is the lack of forest management. This involves burning dead trees in a controlled way so that when a fire does start, there is less     8     for it to burn, and it can be more easily controlled.

Music has been an important part in people's life for a long time. Everyone likes some or the other type of     1     because it has a psychological(心理上的）effect（影响）on their minds. It is seen to give an enjoyable     2     to the listener.

On Dec 9, Zhai Zhigang, Wang Yaping and Ye Guangfu gave a science lesson by     3     on China’s Tiangong space station.

At the beginning of the class, Wang showed us how they live and work     4     the space station. Different from the living environment on earth, to be in good physical health, astronauts must do even     5     exercise every day.

In the end, the astronauts     7     students to do some of the same experiments on earth to enjoy the fun of science.

After having the space lesson, students are more     8     in science. One student from Beijing said, “Watching the space lesson is an eye-opening experience. When I grow up, I am going to be a scientist     9     my country.” “The astronauts made a lot of preparations before the space lesson,” another student said, “I hope there     10     more space lessons from the Chinese space station in the future.”

High school students have to decide something important about their future. Should they go to college after they finish high school? Or should they take a gap year (休学一年) before they     1     to college?
