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.

    Scientists are trying to make the deserts into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming deserts all the time. Scientists may not be able to change the deserts. People are doing bad things to the earth.

    Some places on the earth don't get much rain. But they still don't become deserts. This is because some green plants are growing there. Small green plants and grass are very helpful to dry places. Plants don't let the hot sun make the earth even drier. Plants don't let the wind blow the earth away. When a little bit of rain falls, the plants hold the water. Without the plants, the land can become a desert much more easily.
