    There is a kind of wonderful road in Japan- melody road. {#blank#}2{#/blank#} When you drive on it, you can hear nice songs. There are three melody roads in Japan. {#blank#}3{#/blank#} When you drive on it, you can hear the song Memories of Summer. Lots of drivers like this road very much. {#blank#}4{#/blank#} Many people drive their cars to the road only because they want to listen to the nice song.

    Today,roller skating (滑旱冰)is easy and fun. But many years ago, it wasn't easy at all. Before 1743, peoplenever tried skating on wheels. That changed because of a man named John JosephMerlin. Merlin's work was making instruments. In his free time he liked to playthe violin. Merlin was a man with many ideas and many dreams. People called hima dreamer.

    One dayMerlin received an invitation to go to an important party. He was very pleasedand a little excited. As the day of the party came near, Merlin began to think.He wanted to find a way to make a wonderful entrance at the party. Merlin hadan idea. He thought that he would attract a lot of attention if he could skateinto the room.

    Merlintried different ways to make himself roll. Finally, he decided to put twowheels under each shoe. These were the first roller skate shoes. Merlin wasvery proud of them. He dreamed of arriving at the party and skating into theroom while playing the violin. He was sure that everyone would be verysurprised.

    On thenight of the party Merlin rolled into the room, playing his violin. Everyonewas really surprised to see him. There was just one problem. Merlin had no wayto stop his roller skating. He rolled on, playing the violin. Then, with alleyes on him, Merlin hit into a huge mirror on the wall. The mirror broke intomany pieces with a very loud noise. But nobody forgot Merlin's wonderfulentrance after that.

The Netherlands needs thousands of new houses because the country {#blank#}1{#/blank#}(have) a growing population. Anyway, it may not have to build all those houses. Some of {#blank#}2{#/blank#}(they) can be printed.

 {#blank#}3{#/blank#}(recent), the government has been working together with a university and some building companies to build houses that are fully 3D-printed. As volunteers, an old couple has become the first people in Europe to move into such {#blank#}4{#/blank#} house.

With two {#blank#}5{#/blank#}(bedroom) and a big living room, the house was built layer(层) by layer, using a huge 3-D printer and special cement(水泥). After being printed out, the house {#blank#}6{#/blank#} (carry) by a truck to the building site, and a roof(屋顶) and windows were later added. It took around 120 hours {#blank#}7{#/blank#} (finish) this 3D-printed house. Usually, it takes about one or two years to build a house in the {#blank#}8{#/blank#} (tradition) way.

The couple will live {#blank#}9{#/blank#} this house for six months, with a monthly pay of 800 euros (欧元). The cost seems a little bit high, {#blank#}10{#/blank#} they think it is much cheaper than living in a hotel.

Clever people always bring us new things. They make our life easy. Let's have a look!

Have you ever unlocked a Hello Bike? Have you ever used Meituan to order a meal? Have you ever enjoyed watching the short-form videos on Douyin? Well, if no one had invented the cell phone, none of these would have been possible.

Luckily, someone did invent the cell phone. That person is Martin Cooper, and he did that 51 years ago, in 1973.

Cooper used to work for Motorola. In the 1970s, the company was competing with AT&T, a larger company, to make a cell phone system. Cooper didn't think Motorola's product was good enough. He didn't like AT&T's idea of a car phone, either. The man wanted to give the world something new. He wanted to make it possible for people to talk on their phones anywhere.

It took Cooper and his team 90 days to design (设计) the world's first cell phone. The product was called DynaTAC. People could talk on it for 25 minutes before its battery (电池) died. The phone's short battery life wasn't a big problem, Cooper once joked. Why? Well, the phone was too heavy (1, 100 grams) to hold in hand for too long!

On April 3, 1973, Cooper made the world's first public cell phone call. He called Joel Engel, an AT&T manager. Cooper told Engel, "I'm calling you on a cell phone. It's a real, handheld cell phone." On the other end of the line, there was only silence.

Cell phones have changed a lot since that first call. They're much smaller and can do many more things. Cooper, now 96, is surprised at the progress. But the man has also kept thinking about life in the future. "I must keep learning all my life," he says. "Or I'll lose the ability to learn-that would be terrible!"
