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。
The tomatoes feel very soft.这些西红柿摸起来很软。
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。

2.超级深入的介绍（由于太多，挑了个经典的来介绍一下）Feel 和Feeling 感觉的正确用法①.基本说明feel 是感官动词，后面通常接形容词来形容感觉，如果需要后接一个句子，则用feel like 或feel as if/though 带出。
feeling 是它的名词，当在描述你的感觉时多用复数形式加上–s。
②错误发生及修正A. feel 后面接了不正确的词性例：I feel terribly about this accident. (X)I feel terrible about this accident. (O)记得feel 后面要接形容词，其它类似的感官动词包括smell (闻起来), sound (听起来), taste (尝起来) 等，另外等于be 动词作用的连缀动词look (看起来), seem (好像是) 后面也是接形容词。
B. 用到feel like 但是后面没有接子句例：You feel like in a jungle when you live in the city. (X)You feel like you are in a jungle when you live in the city. (O)feel like 还有feel as if/though 后面都是接有主词有动词的子句。
C. feeling 用了单数表达感觉例：It is necessary to express your feeling from time to time. (X)It is necessary to express your feelings from time to time. (O)不时表达你的感觉是必要的。
feelings 用复数形是指你对某事的看法观感。
例：My own feelings are that you shouldn’t be so mean to your sister.例：He used to hide his feelings in front of people.3.其它记法一感feel,二听hear, listen to, 三让have, let, make,四看see, look at, observe, watch“注意”“观察”“听到”see，还有feel和watch，使用它们要仔细，后接动词不定式做宾语补足语省略不定式符号“to”，此点千万要牢记。
4.类似的介绍表示状态、感觉、情绪、精神活动的动词不可用于进行时。
believe, doubt, see, hear, know, understand, belong, think, consider, feel, look, seem, show, mind, have sound, taste, require, possess, care, like ,hate, love, detest, desire.简单记忆：永远不要说I’m believing … or He is seeing a house. 简单说这些词后面不要随意加---ing.注意：have a party/think about 可以用进行时，因为这里的”have” 意为“举行”; “think “ 意为“考虑”牛津实用英语语法273 位于表示感觉的动词之后A 这类表示感觉的动词主要有see，hear，feel，smell以及listen（to），notice和watch。
