     A terrible mudslide (泥石流) swept through Zhouqu County in northwest China's Gansu

Province on August 7, 2010. Lots of people were killed and injured in the disaster (灾难),

and some are still missing. Now the new school semester began. How about the students there?

     Up till now, most people including teachers and students are still living in the tents. The

students should have started their new semester on August 15. However, the terrible mudslide

disrupted the plan since two schools were damaged and three others were used as resettlement

areas (安置区). The new semester had to be put off for ten days. Also, since many teachers

were killed, parents were worrying that their children might not be able to go to school. Luckily,

54 teachers from neighboring areas were sent to Zhouqu County, and 12 volunteer teachers

arrived there, too. Moreover, all the students got their textbooks and school things for free.

     On the first day of school, a girl said, "The disaster is weighing heavily on my mind (沉重

地压在我的心上). But today school begins. I'm with my classmates again. I feel so happy."

     Zhouqu County has two primary schools, two junior high schools and one senior high school.

The students of the only senior high school had to start the new semester in a school in the

neighboring area. Although the new school is far from their homes, they are happy to return to school.
