If you live in Shanghai or Beijing, you may see some orange bicycles on streets these days. These orange bikes are from a ccalled Mobike, You can order a bike through its app on your phone. When you find the bike, you just scan the QR code(扫描二维码) so you can use it. You don't need to r the bike to a station, just park it somewhere.

    China was known as "the kingdom of bicycles" around 30 years ago. But lately more people don't ride bicycles. They c to drive cars and catch the underground, Now, bike rental(租赁的) services like Mobike are bringing biking b to people's lives.

    Now, online rental services make biking much more fashionable, but it's still not e to ride bikes in Chinese cities. Cars usually take up bicycle lanes. Bikers have to ride next to cars in car lanes, which can be very d.

    This is why Beijing will build over 3,200 km of new bike lanes, according to Beijing Municipal Commission of Development and Reform (北京市发改委). Drivers who p on bike lanes will be punished. Traffic signs will be put on roads to better protect bikers.

My new bedroom is the old one.

    It was very windy when I woke up last Tuesday morning. As soon as I set off for the airport, it began to rain heavily. What a great way to 1 a holiday!

    While I was 2 to the airport, the weather got worse. Suddenly, a huge flash of lightning struck a tree. It came straight down just metres in front of my car. The fallen tree completely blocked(堵塞) the road, so I was stuck. I tried to 3 for help on my mobile, but I failed(失败).

    I was sure that I would miss my plane, so I turned on the radio and tried to get used to the idea. Soon there was a loud knock at the window. I was surprised to see a young man in leather clothes, "Need a ride?" he asked. I took my bags, 4 carefully onto the motorcycle and said in a loud voice, "To the airport please!"

    The young man drove so 5 that I kept my eyes shut all the way. This was my first time on a motorcycle. Suddenly, the motorcycle came to a stop. "Here we are, Sir!" he said. I was just in time for my flight. The young man wished me a nice trip and drove away quickly.

    During the day we work and play, and at night we sleep. Our body has a rest while we are sleeping. Then we can work and play a during the whole day.

    Our body is the best while we are sleeping. Children who are tired usually need more sleep. Boys and girls who are eight or nine years old need ten h of sleep every night.

    What's more(而且),our body needs lots of air w we sleep. If we don't get enough air, we will feel tired after waking up in the morning. While in bed we mustn't cover(盖住) our heads. Our lungs(肺) need to get enough fresh air. If we o our windows at night, we can have enough fresh air, Cool air is b than warm air. If boys and girls want to be strong, they should get lots of sleep with fresh air.

There is  the door.
