1 . How I wish to go to the bottom (底部) of the sea for an adventure (探险)! There are quite a lot of beautiful fishes swimming here around me and they are in different shapes and colors. A big whale or a shark might appear. Frightening, isn’t it? But most fishes are friendly and won’t hurt you if you do not attack them. It would be great fun just to watch the fishes quietly and even play with them. — from Qin Yixing.

Last night, I had a dream. I was flying to Africa. Once I reached the land, I found a jeep to the grasslands. I was about to get into the jeep when I saw a few snakes in front of me. Luckily, they went away without hurting me. Soon I happened to find some nice giraffes and a crowd of zebras. On my way back, there was something wrong with the jeep.

4 . Li Zixuan is a junior middle school student. He is now studying in Grade 9. He has had many dreams since he was little. But as time goes by, some new dreams have appeared and some old ones have disappeared. However, only one dream is still in his mind.

Li Zixuan says that when he was a child, he heard about rockets and spaceships. At first, he didn’t know what they were. From his father, he knew that scientists made rockets to carry things into space, and spaceships were used to carry people through space. From then on, he has had a real interest in space. Every time he sees beautiful stars and the moon in the sky at night, he gets very excited. He is always dreaming that he can fly to space to look at the earth one day. His mother knows about his dream and often encourages him.

In school, Li Zixuan learned that the first man flew into space in 1961 and later, more astronauts succeeded in traveling into space. Some astronauts even landed on the moon. His teacher always encourages him to learn more. He knows not everyone has a chance to travel into space. More importantly, before he can fly to space, he must be trained specially.

Li Zixuan knows it’s not easy to achieve his dream, but he decides to try his best. He says I’ve had this dream for many years. It has brought me a lot of joy and always gives me power. Even if it doesn’t come true in the end, I won’t be sorry.”

It was my dream     1     (become) a volunteer teacher. So three years ago, I left my hometown and taught English in a village in Hunan Province. It is     2     (excite) to work with kids. But it is not     3     (surprise) that being a teacher in the village can be     4     (challenge). The power and water supplies are unstable. Besides, it is inconvenient     5     (go) outside because the public transportation is not well connected. I haven’t seen my parents for more than one year. I miss them a lot.
