为什么要这样用? （英语的）这是一篇完型填空里面的. It had never occorred ,to him before any one of his present students could be the person _____in his dream.有described 和 appeared可以选,但是答案说如果用appeared
为什么要这样用? （英语的）
这是一篇完型填空里面的.
It had never occorred ,to him before any one of his present students could be the person _____in his dream.
有described 和 appeared可以选,但是答案说如果用appeared的话,则使用appearing . 为什么啊?
我再补充一下.
答案解释说,从句子结构分析,described in his dream 为过去分词短语作定语,
如果用不及物动词appear就使用appearing . 我是不明白为什么要用ing 形式。

主要是appearing in his dream可以是现在分词作定语,修饰前面的person；described in his dream可以是过去分词作定语,也可以修饰前面的person.由于appear没有被动形式,所以不能采用过去分词作定语
可以这样理解:appear 指出现，出现是一个过程，如果用ed, 变成 "被出现"，说不通。而describe是指描述，用ed变成被描述，还说得过去。
appeare在这里是不及物动词，没有被动语态，所以不能用过去分词，应用现在分词。
