今天学校又停电了。没有电,我们就没有办法上晚自习,真烦!我望着教室里的窗帘出神,要是有一种多功能窗帘该多好。这种窗帘由一种奇特的纤维制成,纤维中含有微型芯片。窗帘上有三个按钮一白天按下红色的按钮,窗帘就能吸收太阳能;晚上按绿色的按钮,在电灯的照射下,窗帘能散发出恬 Today, the school was cut off again. Without electricity, we would not be able to study in the evening. I was really annoying! I looked at the curtains in the classroom, and if there was a kind of multi-functional curtains, it would be nice. This kind of curtain is made of a peculiar fiber that contains microchips. There are three buttons on the curtain: one day, the red button is pressed, the curtain can absorb the solar energy; at night, the green button presses, and under the illumination of the lamp, the curtain can emit the energy.
