六、［淮北模拟改编］任务型阅读。
Have you ever noticed the sidewalks for the blind in everyday life? They are very important for the people who can't see. Yu Guanbin, a blind man from Shenzhen, showed us the new changes to the sidewalks for the blind in his city.
Yu unluckily became blind over 10 years ago. At that time, it was not easy for him to go outside, as there were no sidewalks for the blind in many places across the city. So Yu easily got lost. He had to stay at home as much as possible. "However, things have changed a lot recently. Most roads in the city now have sidewalks for the blind. I go to work on foot every day," said Yu.
What's more, the new sidewalks are more user-friendly. For example, the sidewalks are 30 centimeters to 50 centimeters away from the green plants along the roads. "On my way to the office, a new manhole cover (井盖) has also been put into use. The sidewalk lies over the manhole cover so we don't need to make a turn like before," Yu said.
Now, most roads have sidewalks for the blind. However, there are still some problems. Some people misuse (滥用) the sidewalks by leaving their cars there. Also, blind people need something that can make sound at traffic lights when they cross the roads. Yu hopes to see more great changes in the future.
