How time flies. In a twinkling of an eye， in 2042， I became a scientist and I was studying a kind of house.
时间过得真快，一转眼就到了2042年，我成了科学家，我正在研究一种房子。
This kind of house has many functions. If there are guests at home and you can't sit down， just press the yellow button， the house will automatically become larger. No matter how many guests there are， you won't feel crowded.
这种房子的功能很多。如果家里来了客人，坐不下了 ，你只要按一下黄色按钮，房子就会自动变大，客人再多，也不会感觉拥挤。
If the guest leaves， you just press the yellow button again， and the house will automatically change back to its original size.
如果客人走了，你只要再按一下黄色按钮 ，房子就会自动变回原来的大小 。
If there is no one at home or you don't feel at ease when you sleep at night， just press the red button， and some invisible police will appear to guard your home， and it won't affect your rest.
如果你家里没人或晚上睡觉不放心，你就按一下红色按钮，就会出现一些隐形的警察，来守护着你的家，并且还不会影响你休息。
If you feel safe， you press the red button again and the shadow police will disappear immediately.
如果你觉得安全了，你再按一下红色按钮影形警察就会立马消失。
With such a house， people don't have to be afraid anymore. I really hope the house I studied can be realized as soon as possible and people can live in such a house as soon as possible.
有了这样的房子，人们就不用再害怕了。我真希望我研究的房子能早点 实现，人们能早点住进这样的房子
