Only after the site at Gonur-depe was excavated were archaeologists able to identify it as coming from Gonur-depe.

【答】as 用作介词，意思是：“作为，是”。

▲identify + 宾语 + as ...，意思是：“表明...是；确认...是”。as 后可以接名词、代词、形容词或动名词等。例如：

1. His boots and purple beret identify him as commanding the Scottish Paratroops. 他的长靴和紫色贝雷帽表明他统领着苏格兰伞兵部队。《柯林斯词典》

2. His accent identified him as a Frenchman. 他的口音让人一下就知道他是法国人。

3. She identified him as her attacker. 她认出他就是袭击她的人。

4. The policeman identified him as the thief. 警察认出他是小偷。

5. Reports have identified him as Tom Stephens. 报道确认他名叫汤米斯蒂芬申。

6. When the woman identified him as the criminal, he had been grilled for two hours. 这妇人认出他是罪犯时，他被拷问了两小时。

▲这类结构叫作“认为...是...”类型。该类动词表示“认为，认可，承认，确认，当作，看作，视作”等含义。例如：

regard him as

consider him as

identify him as

view him as

recognize him as
