该怎么记住faculty,prevalent这两个单词的中文意思?
"prevalent", adj 普遍的,流行的 【记】源于:prevail(v 流行;获胜)
faculty /’fækəlti/【记】fac(可看成fact)+ulty(可看成ugly,丑陋的)→现在社会重文凭不重才能的事实很丑陋。所以faculty是才能,能力的意思。

什么是英语词根
词根(root)是基本构词的基本词素,与词缀相对并携带主要词汇信息。
英语单词构成有其规律,很好的掌握了构词规律,才可以很好、很快的、准确的记忆单词。英语单词构词法的核心部分,在于词根,词的意义主要是由组成单词的词根体现出来的。
词根可以单独构成词,也可以彼此组合成词,通过前缀后缀来改变单词的词性和意义。(词根和词缀叫构词语素)也就是说,单词一般由三部分组成:词根、前缀和后缀。词根决定单词意思,前缀改变单词词义,后缀决定单词词性。
扩展资料:
一个英语单词可以分为三个部分:前缀(prefix),词根(stem)及后缀(suffix)。单词中位于词根前面的部分就是前缀。前缀,可以改变单词的意思。
常见的前缀有如下几类:
第一类:表示正负(或增减)的,如:un-in-im-il-ir-non-mis-mal-dis-anti-de-under-re-over-等;
第二类表示尺寸的,如:semi-equi-mini-micro-macro-mega-等;
第三类表示位置关系,如:inter-super-trans-ex-extra-sub-infra-peri-等;
第四类表示时间和次序,如:ante-pre-prime-post-retro-等;
第五类表示数字,如:semi-mono-bi-tri-quad-penta-hex-sept(em)-oct-dec-multi-等;
其它类别,如:pro-auto-co-con-等。
