Is it good to be in a middle school? Most American children think so. In America, middle schools often have sixth, seventh, and eighth grades. It is different in different places.
For children, going to a middle school is a big change. Most middle schools in America have a special day for new middle school students. On that day, they are showed around the school by their new teachers. And they could know a lot about the history of the school. They also would make friends with the old schoolmates (校友).
They will grow up and learn some different and difficult things in a middle school. A new middle school student will learn foreign languages, computer, music and art, health, and other skills, such as cooking.

If they are good at singing, playing basketball or something else, or if they want to learn, they can join them. Most American children think it's good to be in a middle school.
Cambodia (柬埔寨) is going to open the Angkor Wat temples (吴哥窟) at night to interest more tourists to the poor country.
Tourism is an important foreign currency earner (外汇收入) for Cambodia. More than 1,000,000foreign people are going to visit it this year, and most of them are from South Korea, Japan and the United States. More than half of visitors will visit the Angkor Wat temples.
Now visitors must walk out of Angkor Wat temples at sunset, but Cambodia is going to extend (延长) the visiting hours to as late as 8:30p. m.
"We want visitors to see all views of the temples, even in the dark places where they may not see some of the sculptures and statues," Bun Narith said.
But as hotels are more and more, people need lots of underground water. People say the uncontrolled pumping (无节制地抽水) of underground water is bad for the Earth under the temples.
