掌握词根-van,-ven,-vent的含义
掌握前缀anc-,ant-的功能
词根“-van,-ven,-vent” =come、go,全部都表示“来，走来”的含义。
词根“-anc,-ant” =可以表示“前，前面”的含义。
释义：
advent = ad(=to) + vent(来临，出现)
convene=con(共同，一起) + ven(=come:来)
convenient=con(加强语气) + ven(走) +ent(adj.)
-ance=-ence=-ancy=-ency=N.
N.+ly = adj. ; adj. + ly = adv.
inconvenience=in(相反)+convenience
他们同属于语音同化现象：im- = in- = ir- = il- = i- = 1)相反/否定；2)in的本意；3)使动词‘en’
-able = -ible = ile = adj.(可以...的/能...的);容易;N.
inconvenient = in(no) + conven+ent(adj.)
字母：h/b混子字母，有时不发言，举例：tomb [tum]；climb [klaɪm]；numb [nʌm]
preventive = preventative = pre + vent + ative (ate + ive)
intervene = inter(between) + ven(走) +e
intervening = inter + ven +ing(n./adj.)
revenue = re(回) + ven(来) + ue(n.)
re- = 1)反复/又/在 2)返回 3)相反
event = e(出来) + vent来)
e- = ex- = es- = 1) 向外/出来 2) 超出 3) 前
advance = ad(=to) + vanc(vant/anc)
a- = ad- = 加强语气/去
a- = ab- = 相反
advancement = ad(去) + vence + ment(n./v.)
ancient = anci(=ago) + ent(=ant=的)
ancestor = anc(ago) + cest(=cess=走) + or(人)
antique = anti(ago) + que(名词或者形容词缀)
antiwar = anti(反) + war
anc- = anti- = ant = 以前/反
