“感官”动词用法：）~~

感官动词(及物)有：

see/notice/look_at/watch/notice/observe/listen_to/hear/feel(Vt)/taste(V t)/smell(Vt)

B)连缀动词(含感官不及物)

be/get/become/feel/look/sound/smell/taste/keep/stay/seem/

appear/grow/turn/prove/remain/go/run

一、see, hear, feel, watch, look,这五个动词均可作连系动词，后面接形容词作表语，说明主语所处的状态。其意思分别为"看/听/闻/尝/摸起来……"。除look 之外，其它几个动词的主语往往是物，而不是人。例如：

These flowers smell very sweet.这些花闻起来很香。

二、这些动词后面也可接介词like短语，like后面常用名词。例如：

Her idea sounds like fun.她的主意听起来很有趣。

三、这五个感官动词也可作实义动词,除look(当"看起来……"讲时)只能作不及物动词外,其余四个既可作及物动词也可作不及物动词,其主语通常是人。例如: She smelt the meat.她闻了闻那块肉。

I felt in my pocket for cigarettes.我用手在口袋里摸香烟。

四、taste, smell作不及物动词时,可用于"taste / smell + of +名词"结构,意为"有……味道/气味"。例如:

The air in the room smells of earth.房间里的空气有股泥土味。

另外，系动词又称连系动词，不单独作谓语，必须与表语连用构成系表结构。系表结构可表述主语的状况，而我们对主语情况的了解和描述角度各不相同，因此对主语的表述就因说话人的角度不同，而
