連系動詞后可以接to be嗎

有這樣一道題：

The story sounds __________.

A. to be true                         B. as true                        C. being true                        D. true

此題應選D。該題很容易誤選A。這里涉及連系動詞后是否接to be的題：

1. 在seem，appear，prove，continue等連系動詞以及用作連系動詞的短語turn out等之后，可以接to be，但可省略：

He seems (to be) sad. 他似乎很傷心。

He appears (to be) angry. 他似乎生氣了。

The news turned out [proved] (to be) false. 那消息結果是假的。

2. 在feel，smell，sound，taste等連系動詞后不接to be：

這湯味道不錯。

正：The soup tastes nice.

誤：The soup tastes to be nice.

在look(看起來)之后是否接to be，語法專家意見不一，但總的說來，以不用為佳。

3. 在表語形容詞前的to be通常不省略：

He seems [appears] to be asleep. 他似乎睡著了。

He seemed to be awake when I went into his room. 我進屋時，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. 他似乎對此很有把握。

She appeared to be very fond of the book. 她似乎很喜歡這本書。
