Peer Review of OP

Overall, Monday's groups performed good.

I want to give some comments to Tong. When he spoke, he noticed his gesture, body language, and this is good. Moreover he could care about whether the audience was listening him, which means he tried to interact with audience when he demonstrated.

However, His position, and some gestures looked unnatural. Haha, Maybe at that time he was a little bit nervous.

And One more comment I want to give Zongyang.

His presentation is fluent. As a Chinese fellow who also used English as second language, I think he must push a lot of efforts on preparing it.

However, when he spoke, he always shook his head with a frequency. This looks not so polite. And I found he also didn't get the response from class when he spoke, maybe he rehearsed too many times which leaded his speech like pulling out his memory.

His question answering part is fantastic, by the way.

By this weekends I will update this essay, and go through more details. Good night.
