通过介词英语

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
