1. 连系动词有被动语态吗
Her forehead ______ hot. I’m afraid she is ill.
A. is feeling B. feelsC. is feltD. has been felt
此题应选B。容易误选C, 因为从意义上看, “前额”应该是“被摸”, 所以不少考生误入C的陷阱。
英语中look(看起来), sound(听起来), smell(闻起来), taste(尝起来), feel(摸起来)等表示感官的连系动词, 它们在意义上是被动的, 但在形式上却不能是被动的(因为连系动词是不及物动词, 不可能有被动形式)。同时, 以上连系动词在表示以上意义时, 通常也不用于进行进态(除look外)。
1. The picture ______ beautiful.
A. is looked B. has looked
C. will be lookedD. looks
2. The soup _____ very nice.
A. smells B. is smelt
C. is smelling D. smells to be
3. As is known to us all, glass _____ smooth.
A. feels B. is felt
C. is feeling D. will feel
若以上动词不是用作连系动词, 而是用作实义动词;或者即使是用作连系动词, 而不表示以上意思, 则可用进行时态：
Are you feeling any better? 你感到好些了吗?
He was tasting the pudding. 他在尝布丁。
答案：1. D 2. A 3. A
2. 连系动词后可以接to be吗
The story sounds ______.
A. to be trueB. 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tobe, 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。
3. 要分清是连系动词还是实义动词
a. He looks ______.
b. He looked ______ at his broken car.
A. sad, sad B. sadly, sadlyC. sad, sadlyD. sadly, sad
此题应选 C。这里要分清look用作实义动词和连系动词的两种不同用法。从句意和结构上看：a句中的look 是连系动词(句意为：他看起来很伤心), 所以此句用形容词sad作表语。b句中的look是实义动词(句意为：他伤心地看着他的破汽车;另外句子中的介词at也给我们一定的提示), 所以此句用副词sadly作状语。
以下各例也涉及实义动词和连系动词的两种用法：
1. a. Hearing this, she felt _____.
b. I felt _____ we should take some action.
A. happy, strongB. happily, strongly
C. happy, strongly D. happily, strong
2. a. The dog is too dirty and smells _____.
b. The dog can’t be used for hunting, for he smells _____.
A. bad, bad B. badly, badly
C. bad, badly D. badly, bad
3. a. He worked very hard, and his dream came _____ at last.
b. The boy came ____ to the shop with the money his mother gave him.
A. true, happy B. truly, happily
C. truly, happyD. true, happily
答案：1. C 2. C 3. D
4. 连系动词come, go有何差别
It was a pity that he ______ blind, but to the joy of his family, his dream of becoming a musician ______ true at last.
A. came, came B. went, went C. came, wentD. went, came
此题应选D。句中的go, come都是连系动词, 两者在用法上应注意：
1. 两者用作连系动词, 都可表示事物的变化。一般说来, go主要用于“坏”的变化, 而come主要用于“好”的变化：
These apples have gone bad. 这些苹果变坏了。
Something has gone wrong with the radio. 这部收音机什么地方出毛病了。
Her mother has gone mad. 她母亲疯了。
Things will come right. 一切都会顺利的。
My dream has come true. 我的梦想实现了。
2. 表示像人的生理变化, 通常用go：
go blind 变瞎
go deaf 变聋
go grey 两鬓渐白
go bald变秃 等
但是注意：go 一般不与old, tired, ill等连用。
2. 在表示颜色方面的变化时, 通常用go(有时也用turn，但语气更正式)：
Leaves go [turn] brown in autumn. 秋季树叶变黄。
She went [turned] pale at the news. 她听到这个消息脸色变得苍白。
His hair was going [turning] grey. 他的头发慢慢地变白了。
