    Tom can play basketball and volleyball, and he can swim, too. Mike can play the violin, the drums and the guitar, and he also likes soccer. Tom and Mike like computers very much. Can they join the Summer Camp?

    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.

    We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?

    We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. {#blank#}1{#/blank#}We take minerals (矿物) from the ocean. We can get salt by evaporating (蒸发) seawater. {#blank#}2{#/blank#}such as gold. {#blank#}3{#/blank#}Seaweed (海草) becomes food of many kinds—even candy and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can't drink ocean water. {#blank#}4{#/blank#}But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.

    The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. {#blank#}5{#/blank#}Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.

    We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.

    Do you know Singles Day (November 11) in China? Many people, even your parents, go to bed late that night. They were shopping online to get big savings (省钱). Well, the US has something like it called Black Friday.

Black Friday is the Friday after Thanksgiving. It is on November 27 this year. It is one of the biggest shopping days in the US. People want to start shopping for Christmas gifts, so they go shopping on this day to save money.

It's called Black Friday because shops used to record (记录) sales with black ink (墨水). So when there was a lot of black ink on a page, the shop sold a lot.

On Black Friday, people go shopping at actual stores (实体店). It is different from Singles Day. People stand in line (排队) for hours. Sometimes they fight over things because there are only a few left. TVs, computers and video game systems are some of people's favourite things to buy.
