A．surprising B．was surprisedC．surprised D．being surprised解析：选C.句意：尽管见到我们很惊讶，教授还是热情地欢迎了我们.though 引导让步状语从句，后省略了he was.surprised多指“人对某事感到惊讶”，故选C.★17.—Have you got any particular plans for the coming holiday?—Yes.________，I’m going to visit some homes for the old in the city. A．If ever B．If busyC．If anything D．If possible解析：选D.句意：——你为即将到来地假期做了特别安排吗？——是地.如果可能地话，我将去市里地几家老人院看看.if ever如果，曾经，如：We see them very seldom，if ever.我们难得见到他们.if possible 如果可能地话.由句意可知D项正确.版权申明本文部分内容，包括文字、图片、以及设计等在网上搜集整理.版权为个人所有This article includes some parts, including text, pictures, and design.
