    Bike shares are a growing convenience in many cities around the world. {#blank#}2{#/blank#} Riders usually have to pick up a bike at a self-serve station and return it at another station later. However, a Chinese bike-sharing company called Ofo, is bringing this idea to a new level.

    Like any other bike-sharing service, Ofo users can get a bike at any time. {#blank#}3{#/blank#} Instead, they can pick one up wherever and whenever they please. To get a bicycle, riders with the app are able to find the nearest one. {#blank#}4{#/blank#} After parking the bike, all they have to do is to lock it.

A.Thousands of bike sharing programs have been set up by the governments.

B.When a rider is done with the bike, returning is just as easy.

C.This month, 500 Ofo bicycles will be set up in Cambridge, England.

      One day, a mother crocodile (鳄鱼) and a baby crocodile swam slowly in a riven Suddenly, the mother crocodile saw a monkey, "Oh, a monkey! How nice if I have it for dinner!"

    "My son, can you go and get the monkey for me? I want to eat his heart," the mother crocodile said.

    "All right," the baby crocodile answered.

    The baby crocodile swam near the river bank (河岸). He shouted at the monkey, "Hey, monkey! Would you like some bananas? There are many banana trees over there on the other bank of the river."

    "I like them very much. But I can't swim. How can I get there?" the monkey asked.

    "Oh, I can take you there," the baby crocodile said.

    "Really? Thank you very much!" the monkey jumped onto the baby crocodile's back. In the middle of the river, the baby crocodile went into the water. When he came up again, the monkey was wet all over. "Don't do that again, or you'll kill me!" the monkey shouted.

    "I know, but I must do that! My mother wants to eat your heart."

    "My heart? Why didn't you tell me earlier7 I left it in a tree. We should go back for it!" So they went back.

    As soon as they got to the bank, the monkey picked up a big stone (石头) and climbed up onto the street quickly. He shouted at the baby crocodile, "Don't you want my heart? Well, catch!" The monkey threw(扔) the big stone at the crocodile.

    An 11-year-old blind girl is proud of walking alone every day to and from school. Why? She has to walk past so many barriers (障碍物) in her way. The girl's home is near the school, yet her mother follows her without letting her know.

    The case of the girl shows the barrier-free facilities (设施) are not enough in her city. Many other cities are short of barrier-free facilities as well. There's no well-designed path for the blind. In fact, in the early 2000s, some cities started to build barrier-free facilities for disabled people. However, almost 20 years later, only a few large cities have had facilities of high quality.

    It's common that sidewalks are taken up with barriers. Few workers are sent to move them away, so it's dangerous for the blind to walk on them. Also, some other barrier-free facilities are badly destroyed（毁坏）. Only a few workers are assigned (分配) to do the task of repairing the broken ones.

    Some ideas can make a difference-build more barrier-free facilities and employ more of them require money. In a word, more money is needed to carry on with the work. It's our duty to make life easy for disabled people, so that they can live without barriers some day.
