What could the school of 2050 look like? Undoubtedly, the biggest development we     1     (see) in recent years is the advancement of technology. On entering the classroom, biological recognition scanning will allow students to check in,     2     (simplify) the busy registration process. Teachers will be able to automatically sort out the attendance data, fill in perfect record, and manage     3     (track) the patterns for being late.

For the school of the future, there will be no need to wrestle with heavy     4     (curtain)or dust- covered blinds; we’ ll have smart glass. Windows can automatically adjust     5     (them) color to make up for external brightness, protecting both our eyes and screens.

As summer temperatures continue to rise, the general trend for 2050 is warmer, drier summers as well as warmer, wetter winters and air-conditioned classrooms,    6     will be-come the norm(常态). But they will be    7     (clean), more flexibly and sustainable(可持续的), with built-in air purifiers to remove toxins and dust from the air.

    8     2050,3D printers will have become a standard appliance, both in the home and at school. As    9     learning aid, they will have become essential, allowing teachers more flexi-bly to explain difficult concepts.

Students will be able to     10     (physical) operate objects for better information process-ing, visual perception, and cognitive(认知的) learning.
