1. 小學六年級下冊用英語描述一下自己喜歡的小發明，不少於60詞
自行車在路上行駛的時候，由於沒有後視鏡，身後的情況不清楚，而且又很危險。我想發明一個自行車後視鏡。先把一個鏡片粘在一塊木板上，再把木板粘在一個鐵棒上，然後，把木板和鐵棒固定在車板上，這樣，自行車後視鏡就做好了，只要一看鏡片就可以知道後面的情況，再也不用回頭看了。
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.
