Death valley (死亡谷) is famous for its moving rocks. Since the early 1900s, visitors to Racetrack Playa, a dry lake bed in California have wondered how the rocks can move on their own.

These rocks leave long tracks (轨迹) behind them. The long tracks show that the rocks have moved along the ground. Those rocks only move at night and only move once every year or two. And they don’t move at the same time or in the same direction. But how do they move? How can a 350-kilogram rock move? Now scientists have known the key to the question!

Here’s how it happens.

Death Valley is one of the hottest places in the world, but it is cold at night. When it rains, the hard ground becomes soft and wet. When it gets cold enough, the water on the ground will change into very thin ice. Then the strong wind can move flat (平的) rocks along the flat ground In the morning, the sun comes up and dries the ground.

Moving rocks can be found at other places in the world as well, but Death Valley is the most famous.

Black Friday

Thanksgiving is always on a Thursday. The day after it has been known as Black Friday. It is the start of the holiday shopping season, and it has been the busiest shopping day of the year in the US since 2005.

Most stores offer big sales on Black Friday. They open their doors quite early in the morning. They try to attract(吸引) shoppers with big discounts (打折). Some items (商品)like TVs and cloths are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

Black Friday is a great time to go shopping. However, there are problem. The biggest one is that there are not enough low-priced items. Each store may only have a few. These items are in great need, so people stand in long lines to get them. They may wait three to four hours before a store opens. They may be hoping to get a low price on a TV or computer, but not everybody can get one. Some people leave, disappointed(失望).

The situation makes people worried. Some Black Friday events have been crazy. There have been fights over toys among shoppers. Some workers have even been hurt by large crowds. But most Black Friday events are safe and fun. Still, if you plan to go, you will expect large crowds and a bit of pushing.

So where does the name “Black Friday” come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it caused. In the 1960s, stores tried to rename the day “Big Friday”. It did not stick. The name “Black Friday” continued to spread across the country. It seems that it is here to stay.

Now people all over the country take part in Black Friday events. It is even spreading to other parts of the world. Stores have held Black Friday events in the UK, Australia, and Brazil since 2012. In Mexico, stores offer a weekend of discounts every year. They call it “El Buen Fin”, which means “the good weekend” in Spanish. I guess people everywhere like to buy things on sale.

1.Is Black Friday the start of the holiday shopping season?

2.What is the biggest problem with Black Friday?

3.How long may people have to wait before a store opens?

4.Do you like to buy things on sale? Why or why not?
