?請看題：
The boy said that the fish his mother cooked tasted ______.
A. good B. well
C. to be good D. to be well
【分析】按英語語法,連系動詞后通常接形容詞作表語,而不接副詞,據(jù)此可以排除選項B和D.但到底是應選A還是C呢?許多同學憑感覺認為 taste to begood 似乎很通順,于是選了C.但是,錯了,正確答案應是A.原因是用作連系動詞的 taste 后習慣上不接to be.如：
這棵樹上的蘋果味道很好.
正：The apples from this tree taste delicious.
誤：The apples from this tree taste to be delicious.
類似地,feel, smell, sound 等連系動詞后習慣上也不接不定式 to be.如：
你的想法聽起來很好.
正：Your idea sounds a good one.
誤：Your idea sounds to be a good one.
玫瑰發(fā)出香氣.
正：Roses smell sweet.
誤：Roses smell to be sweet.
比較：seem, appear, prove, turn out, continue 等連系動詞后可以接不定式 to be,也可省略 tobe.如：
She seems (to be) a little tired. 她似乎有點累.
He appears (to be) quite young. 他顯得年輕.
The examination turned out (to be) quite easy. 結(jié)果考試相當容易.
The weather continued (to be ) fine. 天氣仍然很好(.
注：用作連系動詞的 look 后能否接 to be,各語法家意見不一：有的認為可接to be,有的認為不能接 to be.為此,建議同學們以不接 tobe 為宜.
