Chokwe Selassie is on a mission to help drivers avoid potholes (路面坑洞) .The eighth-grader got his inspiration on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. “I decided I was going to do something about the pothole problem in my city,”said Chokwe. His solution: an app that warns drivers when there is a pothole ahead.

Chokwe developed the app with his friends,“When the app detects a pothole, it is highlightedin red,” Chokwe says. “And if you get close to the pothole, your phone will warn you with a beep.” Drivers can also use the app to report any potholes they encounter, and to look for other routes they can take to avoid roads that have them.

The app relies on current available information about the streets of Jackson. “It works by using the city’s 311 call system, soit uses information already stored in a database,” Chokwe says. Throughthe call system, citizens dial 311 to report non-emergency problems—which include potholes. As Chokwe and his friends worked on the app, they also went street by street throughout the city. They determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test it.

Although the app isn’t yet available for sale,Chokwe is already looking for ways to improve it. The app remains limited to 10 streets in Jackson, but he hopes to add more, so that it includes every street in the city. And then he wants to go even farther. “I want to keep working on the app until it’s nationwide, ” Chokwe says.

Chokwe Selassie got the idea to develop the app from ________.

A.his own experience

B.a recent news report

C.his friends

D.his mother

When you are close to a pothole, your phone will warn you with ________.A.a voice report

Drivers can also use Chokwe’s app to ________.A.report emergency traffic problems

B.look for information other than potholes

C.choose safer routes without potholes

D.avoid traffic jam caused bypotholes

To develop the app, Chokwe and his friends ________.A.reported potholes to 311 call system

B.conducted field trips onthe streets

C.built their own information database

D.collected samples in their neighborhood

We can learn from the last paragraph that Chokwe ________.A.is quite successful

B.is facing difficulties

C.has regained hope
