1.We have been looking for the boy all the afternoon but he is nowhere _.(D)
A.to see B.seeing C.seen D.to be seen
C为什么错
一、选择 Seen 是个完整的并列句：
第一分句：We have been looking for the boy all the afternoon
该分句用的是现在完成进行时态,表示从过去的某个时刻一直都在找,而且说话时依然在找着.
第二分句：but he is nowhere seen
其中副词 nowhere = not anywhere,因此可以第二个分句可以改写如下：
but he is not seen anywhwere.
改写后可以发现 is seen（助动词be + 过去分词 ）是被动语态,直译出来就是“他没有地方被看到”.
二、若选择 to be seen,句子就成为 he is nowhere to be seen,那么, he is nowhere 则成了系表结构,即 nowhere 是表语,说明主语所在的处所
意思是“他那里也不在”.如果是这样,动词不定式 to be seen 应该做什么成分呢?
1）如果是定语,则修饰 nowhere,意思成了“他在看不到的地方”；
2）如果作状语（不定式只能作目的或结果状语）,意思讲不通.
