depress = de + press(压)→ 向下压 → v. 压抑
descent =de + scent(爬)→ 向下爬 → v. 下降
de-表示“使...加强”
declare = de + clar(clear清晰)+ e → 大声澄清事实 →v. 宣布
define = de + fin 1(范围,结束;final = fin + al → 有范围的,会结束的 → adj. 最后的)+ e → 划定范围 → vt. 下定义,限定
demonstrate = de + monstr(显示,表示;monster = monst + er → 太显眼的 → n. 怪物)+ ate → 加强表示 → vt. 论证,证实
