1．A.worried　　　　　　　 B．sad

C．surprised D．nervous

C　解析：通读全文可知，作者是一个中国大学生，中国人学英语，尤其是初学者习惯使用英汉词典。当作者看到英英词典的时候，他感到"吃惊"。

2．A.Because B．Although

C．Unless D．If

B　解析：前后两句在意义上是让步关系，所以用although引导让步状语从句。而because引导原因状语从句；unless和if引导条件状语从句。

3．A.but B．so

C．or D．and

A　解析：此空处是一个并列连词，连接前后两句。而前后两句之间存在的是转折关系，所以用but。

4．A.difficult B．interesting

C．ambiguous D．practical

A　解析：最初用英英词典，不习惯，所以作者感觉用起来很"难(difficult)"。interesting是"有趣味的"，根据下文not fully understand the meaning不可能是这个答案；ambiguous是"不明确的"；practical是"实用的"，这两个词也不符合语境。

5．A.thus B．even

C．still D．again

C　解析：句子中有否定词not，有副词fully，所以用still，表示"仍然不能够完全"的意思。

6．A.new B．familiar

C．earlier D．ordinary
