题目：The science and technology slightly invents
Schoolmate will buy some biscuits to put frequently to the family, will treat as between-meal snack to eat, but the common lid will not be good, as soon as will bump gently, falls ground, the cover has gone immediately bad, the inside biscuit has leaked completely, will not be very good tidies up. As soon as also has the time which the biscuit puts to be long, biscuit easy bad, not able to eat all has to discard the biscuit I to puzzle over for this reason, has thought of perfect means finally. I knows nothing about to the biscuit, but I knows something about to the box. The biscuit lid not tight is because inside has the air, but the biscuit easy to deteriorate, is also because contacts the air, so long as let in the cracker box not have the air to be good. But how can find time the air, I open when the drawer seeks for the material, pulls open the drawer suddenly to have a Rafale, has been right, makes a pinhole under the cover, makes an elephant drawer same thing in the side, so long as does not stop pulls out pulls the drawer, the air is suitable slightly is pulling out spatially, inside box's air will be found time, such lid so will not be easy to fall, regardless of you will buy, in many biscuits will only put to this kind of box inside did not fear that was bad. Moreover you do not need to go to the summary to be able desirably to find time with how many times the air, so long as you have pulled have pulled, waited for you not to draw the inside air also not to have, you did not need the worry to be able not to be able to pull out, as soon as so long as pulled out gently is good. is what kind, is my technical daily life small invention both practical and simple!
科技小发明

同学们经常会买一些饼干放到家里,当作零食吃,可是一般的盒盖不好,轻轻一碰,摔到地上,盖子立刻就坏了,里边的饼干全部漏了出来,很不好收拾.还有饼干放的时间一长,饼干就容易坏,吃不了只好把饼干扔掉为此我伤透了脑筋,终于想到了一个十全十美的办法.

对饼干我一窍不通,不过对盒子我还是略知一二的.饼干盒盖不紧是因为里面有空气,而饼干容易变质,也是因为接触到空气,只要让饼干盒里没有空气就行了.可是怎么才能把空气抽空呢,我打开抽屉寻找资料时,拉开抽屉突然有一阵风,对了,在盖子下面弄一个小洞,在侧面弄一个像抽屉一样的东西,只要不停地抽拉抽屉,空气顺着小空抽出来,盒子里面的空气就会被抽空,这样盒盖就不会那么容易掉下来了,无论你买在多的饼干只放到这样一个盒子里面都不怕坏了.而且你不用刻意去记要用多少次才能把空气抽空,你只要一直拉一直拉,等你拉不动了里面的空气也就没有了,你也不用担心会拔不出来,只要轻轻一拔就行了.

怎么样,我的科技日常生活小发明是不是既实用又简单!
