It's very important that we all recycle.In nature,everything1 again.For example,when an animal dies,it becomes2 animal's food.Nothing is wasted.But humans have created things like plastic bags which can't be3 down by nature.Our4 kills animals and pollutes water and soil.5 we continue making too much rubbish,the problem will only get worse.If nature can't reuse the rubbish,we must recycle6 .We should clean up the rubbish we've made because nature can't.

    Recycling is also the right thing to do for another reason.The earth is rich in natural materials like water and trees,7 these materials are not endless (无尽的).We use up our natural materials8 faster than the earth is able to reproduce (再生) them.For example,each year we cut9 more than 6,000 square miles of forest.But it takes an average of 25 years for a new tree10 .

    Recycling can help us save the earth,so let's take action right now.

    In real life, robots are mainly used in factories. They do many different jobs. Usually these jobs are too 1, difficult or boring for humans.

Robots also help disabled people and people who cannot look after 2. For example, scientists are making a robot to help 3 people. Now many of them have a dog to help them. The dog is called a guide dog. In the future, guide dogs might be robot dogs.

    XBOX 360 Kinetic, RoboSapien, WiiParty, theseare just a few of the modern toys sold in recent years. But some of the most populartoys are actually quite old.

Gameshave been around for thousands of years. In 4000 B. C, Babylonians played a boardgame that was similar to chess. Yo-yos made of stone were first used in ancientGreece around 1000 B C. And kites appeared in China around the same time.

    Another famous game is Scrabble. It was inventedby an architect in the 1930s, but it didn't get popular until 1953 And since then,more than 100 million sets have been sold worldwide.

    Some toys go out of fashion, but then becomepopular again, such as Rubik's Cube. Research says parents are increasingly choosingto buy toys they remember from their own childhood.

    These days, toys are not just for fun. RoboSapienis a remote-controlled robot that was launched in 2004. He can walk, turn aroundand do other poses. RoboSapien was designed by Mark Tilden, who once created robotsfor NASA space missions. He expected the toy to be used mostly by and scientists,but almost 2 million RoboSapiens have been sold worldwide since its launch as atoy?
