2. The dictionary is ______: many words have been added to the language since it was published.
A项 out of control 意为“失控”；
B项 out of date 意为“过时”，
C项 out of sight 意为“在视野之外”；
D项 out of reach 意为“达不到”；
A、C、D三项均不符合文意，故正确答案为B。
根据下文“many words have been added to the language since it was published”可知，自从字典出版以来，已经有很多的新单词加进来了，由此可见，这本字典已经有些“过时”了。
常见短语含义记忆不准致错。
