英语的常用介词都有哪些(包括常用介词短语)

你的这个问题太大了。常用介词随便也有二三十个,如：at,in,on ,beside,by,near,behind,but,except ,besides,among,between,from,to,with,without,about,like,into,onto,through,before,against,along,during,for,of,off,past,since,towards,until,within,up,down,per,over,upon,till 等等。而常用介词短语,同样多不胜数。自己平时要善于积累。以in为例,可有：in the morning(afternoon,evening。)in the sun(rain,snow,wet,dusk。)in danger(peace,poverty,fashion,comfort,blossom。)in fear of(excitement,doubt,hope。)in October(summer,2005。)in rags(ruins,knots,fun,joke。)in a hurry(circle,line,a queue。)in English(price,length,ink。)in red(white。。。; short,brief。。。)简直不胜枚举,就不一一举例了。
