上周六，我去了一趟长城。我在那里见到一个奇怪的外国游客。这位游客是个盲人，但他随身带着一个。机器人能够用眼睛拍照，它还能告诉他看到了什么。机器人告诉他哪里停下或到哪里去。它也能够记住他说的话。多棒的机器人啊！我也想有一个这样的机器人。
Last Sarturday, I paid a visit to the Great Wall. There, I met a strange foriegn tourist who was a blinder.To my surprise, there was a robot with him.The robot could take photos with its eyes, and could even tell his owner what it saw just now. The robot told him where to stop and where to go. It could remember what he said as well. What a terffic robot! I hope I can have one like this.
