Inventins make ur life easier and better. A big inventin makes us feel it all the time. There are als small inventins arund us which are 1 and interesting.
D yu ever find it annying t lk fr the TV remte? Are yu tired f 2 shes when playing different sprts? Dn't wrry. Students at Claytn Middle Schl in the US might be able t 3 yu.
Dylan Glick, an 8-grade student, thught 4 the idea f a "retractable remte(可伸缩遥控器)". The remte has a rpe t cnnect with its resting place. 5 peple push a buttn n the remte, the rpe will give the remte back t its resting place.
"It is smething that I wuld use, and I'm sure 6 parents wuld use, t." said Glick. He said that smetimes at night when he wants t g t bed, he needs at least ten minutes 7 the remte. S he came up with the 8 .
Allisn Bicking, als a student in Grade Eight, had 9 similar idea. Bicking is a sccer player. She 10 spiked shes when she practices running. If she plays sccer after she runs, she has t change her shes.
T slve the 11 , she designed many kinds f shes. Finally, she invented "speedy spikes(钉鞋)" after three mnths' hard 12 . The spikes are retractable with a small buttn n each she. If yu push the buttn, the spikes will cme ut r g back int the she 13 , making the shes suit different kinds f sprts. It seems that inventing smething is nt 14 . Inspiratins(灵感) always cme frm yur daily life, s keep yur eyes pen. Maybe the next great 15 wh will make a difference t ur life is yu!
