英语介词有:in、on、for、at、about、under,用法如下:
一、in的用法:
in用在一些动词、名词、形容词后面,以引出附加信息。in 还与表示动作的动词连用,如 walk,push等,还用在诸如 give in,dig in 等短语动词中。
in作介词在句中弱读,作副词在句中重读。指能用in的表达方式有in the morning,in the afternoon,in the evening和in the night。
二、on的用法:
日期前的on常被省略。表示“手脚上的斑点”时,应用介词on;on the river在不同意境下,意思不同。
三、for的用法:
for是并列连词,引导的是并列从句,表示原因的语气很弱,一般是对结果作出推断性的补充说明或解释,不表示直接原因, for前多加逗号。
四、at的用法:
用于地方时,at指较小的地方,如指城镇时。
说到商店、机关、学校等,假使看作一个地点(point)用at。假使看作一个场所(place)用in,the barber's (理发店),Green's (Green所开的店)等前面只用at。
说到门牌用at,如live at 1184 Zhongshan Road,路名前面该用in,而说“在……路口”用at。
用于时间时,可表示时刻,如at night,at three o'clock,at any time等。也可表示较短的时期。
五、about的用法:
在指“不久就要……”时,后通常接不定式,如about to start。也有接动名词,如about starting。但是不可再加表示时间的词,如不可说about starting at once。
六、under的用法:
under表示静止的空间位置时,意思是“在…的正下方”“在…的下面”; 也可指在某物的脚边或底下,即“在…底下”“在…脚下”; 还可指在人身体某部位之下; 有时还可引申表示“在…遮蔽〔保护〕之下”。
介词又称作前置词,表示它后面的名词或代词(或相当于名词的其他词类、短语或从句)与其他句子成分的关系。介词通常位于名词或代词之前。
介词是一种虚词,不能单独作句子成分,只能用在一个名词、代词或相当于名词的结构之前,可以与后面的词一起构成介词短语。
介词与不及物动词搭配,不及物动词不能够直接跟宾语,且没有被动语态。但是和介词搭配后,不及物动词不但可以跟宾语,也有了被动语态。
常用介词短语:
after all 毕竟,到底
day after day 日复一日
one after another 接二连三
page after page一页又一页地
