连系动词后可以接to be吗

连系动词后可以接to be吗
 
有这样一道题：
The story sounds __________. http://yingyu.chazidian.com
A. to be true                         B. as true                        C. being true                        D. true
此题应选D。该题很容易误选A。这里涉及连系动词后是否接to be的题：
1. 在seem，appear，prove，continue等连系动词以及用作连系动词的短语turn out等之后，可以接to be，但可省略：
He seems (to be) sad. 他似乎很伤心。
He appears (to be) angry. 他似乎生气了。
The news turned out [proved] (to be) false. 那消息结果是假的。
2. 在feel，smell，sound，taste等连系动词后不接to be：
这汤味道不错。
正：The soup tastes nice.
误：The soup tastes to be nice.
在look(看起来)之后是否接to be，语法专家意见不一，但总的说来，以不用为佳。
3. 在表语形容词前的to be通常不省略：
He seems [appears] to be asleep. 他似乎睡着了。
He seemed to be awake when I went into his room. 我进屋时，他似乎醒了。
He doesn’t seem to be afraid of it. 他似乎不怕它。
He seems quite sure of it. 他似乎对此很有把握。
She appeared to be very fond of the book. 她似乎很喜欢这本书。
