It seems like... 那好像是……
"It seems like..."的意思是“好像，仿佛感到”。"it"是形式主语，具体的内容在"like"后面。也可以说"it seems that..."。
1. It seems like there are hundreds of people in the room, it's too crowded and noisy.
2. It seems that nobody knew what had happened.
3. It seems that something is wrong.
A: Mary, do you remember when we met?
B: I won't ever forget it! I was sitting in the cafeteria all by myself...
A: And I came up and asked to sit by you...
B: Oh, it seems like it was just yesterday.
as if 暗含的意思是“仿佛是，但实际上并不是”。例如：He talks about Rome as if he had been there before（他说起罗马来好像他以前去过罗马似的）。
