1. 小学六年级下册用英语描述一下自己喜欢的小发明，不少于60词
自行车在路上行驶的时候，由于没有后视镜，身后的情况不清楚，而且又很危险。我想发明一个自行车后视镜。先把一个镜片粘在一块木板上，再把木板粘在一个铁棒上，然后，把木板和铁棒固定在车板上，这样，自行车后视镜就做好了，只要一看镜片就可以知道后面的情况，再也不用回头看了。
When the bicycle on the road, because there is no behind the rearview mirror, the situation is not clear, but it is very dangerous. I want to invent a bicycle rearview mirror. To stick a lens on a piece of wood, and the wood stick in a bar, and then, the wood and iron bars fixed on the template, so that after the bicycle mirror is done, as long as a look at the lens can know behind, no longer have to look back.
