以前在chinaunix回答过这样一个问题,用到了正则表达式(而且我认为正则式解决此类问题是最合适的。)
学英语的一些例句,每句都有若干词根相同的词,例如 She swears to wear the pearls that appear to be pears. 但是每句的词根都未必相同;我希望把这些包含词根的词都标记出来,请问如何写?
这里说的词根不是原本词根的定义,只是一组字母序列,比如
9. The dust in the industrial zone frustrated the industrious man.
词根是dust或ust
10. The just budget judge just justifies the adjustment of justice.
词根是dust
11. I used to abuse the unusual usage, but now I’m not used to doing so.
词根是use,有变形
12. The lace placed in the palace is replaced first, and displaced later.
词根是lace
13. I paced in the peaceful spacecraft.
词根是pace
14. Sir, your bird stirred my girlfriend’s birthday party.
词根是ir
