In Japan, the latest time—saving invention is a dog-washing machine. Dog owners can buy one for their dogs. They can save time by putting their dogs in the machine and then 33 minutes later, a clean, fresh-smelling dog comes out.

    The machine becomes more and more popular. The sales of the dog-washer are increasing. The machines save a lot of money for pet owners. However, it's bad news for pet hospitals because they are losing many customers.

    The washing machine has many advantages. First, the whole cleaning process includes a shampoo（洗发）, rinse（冲洗） and blow-dry. Second, tests showed that dogs enjoyed the wash and were very happy when the blow-dryer started working. Third, the most important is that the makers of the machine say it's very safe and does not harm dogs in any way.

    One dog-owner, Michiko Kobayashi, loves her new machine. She said her dog was happy, too. Michiko explained to the reporters, "Before I bought my washer, I only took my dog to the pet hospital a few times a year. Now, I wash her every week and she looks great. I also save a lot of money. "

    It is welcomed by most people who raise dogs. And it takes over the market quickly. What a beautiful invention!

Paper cutting is one of the oldest Chinese traditional skills. People first started paper cutting in the 6th century. Scissors and paper are usually u{#blank#}1{#/blank#} in paper cutting. People cut different patterns like animals, plants and Chinese characters for health or good l{#blank#}2{#/blank#}. Zhang Xiufang is an inheritor (传承人) of Yangzhou Paper Cutting. Her works always make a deep i{#blank#}3{#/blank#} on others because she can cut fine patterns without cutting the paper into pieces. A{#blank#}4{#/blank#} she is 81 years old now, she keeps on p{#blank#}5{#/blank#} the skill every day. She hopes this valuable traditional skill can be passed down from generation to generation.

Every living thing needs to reproduce（繁殖）. Reproducing means creating more members of your group. In order for plants to reproduce, they have to spread their seeds（种子）to other areas. Plants have developed all kinds of ways to do this.

The simplest way is gravity（重力）. Many seeds are inside of fruit. When fruit gets too heavy, it falls from a tree to the ground. Sometimes animals will pick up the fruit and drop it in another area. That helps move the seed even farther away. Apples spread this way.

Other plants use wind to spread their seeds. Dandelions（蒲公英）are a good example of this. Dandelion seeds are so light that when wind blows, it carries dandelion seeds to new places. Maple（枫树）seeds also use wind. Their seeds are connected with long, thin leaves that look like wings. When the seed falls from the tree, its "wings" help it fly farther from the tree.

Some animals help plants spread their seeds. The animals eat the seeds. While the seed is in the animal's body, it stays whole. When the seed leaves the animal, it's in a new place.

Ants also help spread seeds. Some seeds have a special smell that appeals to ants. The ants bring the seeds back to their home, which of course is underground. They only eat part of the seed. They leave the rest of the seed underground. After that, the seed can start growing.
