When a computer runs a group of programs, it can get very Cooling the computer can cost a lot. So some scientist's wonder what will happen if the heat from the computer can be used.

    Large Internet companies (公司) such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems(系统). These systems send the heat into the air.

    A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-radiator.

    Boaz Loupe, the head of the company, says the e-radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer. So the users don't have to pay to cool their computers.

    Five homeowners in Holland are testing the heating system in their homes.

    "We pay for the computer using, so, in that way, homeowners get heating for free," Boaz says.

    Jan Visor is one of the homeowners. "If you use the computer more the e-radiator produces more heat," he says. "It cannot provide enough heat if you don't use your computer often. "But he is ready to try it. It's a great help for his family.

    The company says e-radiators can produce heat at a temperature of 55℃. It says the system can save its users about S 440 a year.

    Children today have many things to play with. They can watch television, surf  Internet, or play video games. But what do you think children  (do)for fun long ago? They read books.

    Some of you might ask, "Are books  (real) fun?”

    Believe it or not, books can provide many things that televisions or computers cannot. Since books use only words  (tell) a story, they can improve your imagination. You can picture the characters and background in your head and you can also imagine  the characters feel.

    The words and sentences that are used in stories are also very interesting and usually cannot  (find) often on television or on websites. They are sometimes so beautiful and touching  they can bring tears to your eyes Books also help us to think harder and  (deep). As we continue to read, we ask questions to  (our) and try to find answers.

    These are some of the  (reason) why books are so fun to read. Remember that the more you read, the more you grow.

    Years ago a heavy rain hit Chongqing and made the Yangtze River rise.

    When the rain stopped, people found that a dog, later named Huahua, swam across the river to an island(小岛)twice a day for two weeks. Why? Because Huahua's four children were there. The mother dog swam there every day to feed her babies. This story touched many people

    Not only humans but animals are responsible. Animals know love as we humans do, and Huahua is only one of them. British scientist Jane Goodall spent 14 years living with chimpanzees(黑猩猩) in Africa. She found that chimpanzees cared for each other when others got hurt or lost parents.

    Two birds in Chengdu showed their parental love. Their baby was hurt and fell on the street in the centre of the city. Cars were driving past but the brave parents flew down to the road and took the little bird away with their claws(爪子).

    Animals not only love their own children, but also care for other animal babies. A chimpanzee named Anjana in an American animal research centre takes care of a baby lion. She feeds the lion carefully every day. "They are just like mother and son, "said a worker at the centre.
