One afternoon, in Paris, Kate visited an art museum. She enjoyed seeing some great paintings in a quiet place like that. But a young man and his wife talked all the time. Kate watched them because of the noise and decided to go away.

    Kate met them many times when she walked through the museum. Every time Kate heard their noise, she left quickly.

    Kate was buying cards at the gate of the museum when those two people got there, too.

    “He's a brave man,” said the shopkeeper. “Most of us would give up if we were blind (失明), but he and his wife come when there's a new art show anytime.” “But how does the man enjoy the paintings?” Kate felt very sorry and asked.

    “His wife tells him about every painting.”

    At that moment Kate knew what patience (耐心) and bravery are. Kate saw patience from the wife and bravery from the man. He would not let blindness change his love on art.

    We can see many people riding shared bikes in China now.

    Bike-sharing helps people to borrow a bike from one place and return it at another place easily.

    This kind of bike has GPS or Bluetooth on it. You must have a smart phone if you want to use it. First, you have to download (下载) an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan (扫描) the QR code on the bike and you will get the bike.

    Then you can enjoy your trip. What's more, you can easily find one and don't have to worry about where to park it. Every hour you ride, you need to pay only one yuan. It doesn't cost so much, does it?

    Science changes our lifestyles. Bike sharing makes our life easier. And we also hope that people can not only enjoy it but also put it to good use.

    In the UK, bus journeys are very common. Buses are often convenient(便利的）for the people who live or work in the city center. Passengers can avoid heavy traffic and do not have to pay for the parking. However, taking the bus is just a necessary but boring part of life: they get on the bus, pay for it and sit down or find a place to stand when it is crowded. Everyone seems sad and bored. 

    In Latin America, however, bus trips can be wonderful. For a start, films are showed on the buses between cities for passengers to have fun along the journeys. Local buses do not show films. but drivers usually turn on the radio and it can be great for passengers to listen to songs and get relaxed. 

    Even better than films and music are the sights and sounds on the buses. Local buses always go to parts of the town that passengers would not visit by themselves. There passengers can see shops that they have never heard about. And they can also see other cultures of the town from the windows of the buses.

    Besides passengers' luggage(行李)is also interesting. It is common to see a happy dog's head getting out of somebody's bag or a lovely chicken "speaking cheerfully "under somebody's arm. Once on a bus in Peru a farmer even tied a sheep to the top of the bus. It was quite surprising.

    In all, taking the bus in Latin America is really fun and unforgettable.
