翻译并分析
答
原句可以扩充为although the professor was suprised to see u, he gave us a warm welcome.为了避免重复，所以简写。但也可以写成suprised to see us ,the professor gave us a .....
注意前后主语一致就可以了。
答
省去he was, 前面一句是从句，与后面的主语是一个人，表伴随状态，省掉主语和be动词，要注意，是一起省
答
完整的句子是,though the professor was suprised to see us,the professor gave us a warm welcome.当主从句主语一致时,可以省略从句中的主语和be 动词,所以就是though suprised to see us,选c.
