Have you ever used your fingerprint to open a door? Have you ever taken a self-driving taxi on the road? Technologies have brought     1     changes to our life. Actually, changes can also be     2     in your school.

“Now, we don’t have to     3     to the canteen (食堂) as soon as the bell rings,” says Hu Liang, a student from Jiangxi. His school introduced a smart canteen system (系统) this year. Students choose meals online first. When it’s time for their orders, they pick up meals     4     using facial recognition (人脸识别) technology. The smart canteen     5     students enjoyable experiences. At the same time, it helps the school plan meals and reduce kitchen waste. Besides providing     6     food, the smart school also tries to help students develop good living habits.

Recently, a middle school in Chongqing has used four     7     on the playground to follow students and record how fast they run. They can     8     see the top ten students on the screen. That adds fun to running and makes students compete in an interesting     9    .

What other exciting technologies could be part of our life in the     10    ? Let’s look forward to even more changes!
