[ˌʌndǝ′maɪn]　(undermines; undermined; undermining) 双解释义 1. vt.削弱…的基础　 wear away the earth beneath, removing support 2. vt.逐渐损坏　 weaken or destroy gradually 基本要点 1. undermine的基本意思是“削弱…的基础”，指逐渐地、常不被人察觉地破坏某一事物的根基，而使其遭到损坏，这种破坏可源于自然，也可源于人为破坏。 2. undermine是及物动词，接名词或代词作宾语，可用于被动结构。 3. undermine引申可作“损坏”解，这种损坏不是突然间的，而是有一个长期的过程，用作及物动词，接名词或代词作宾语。 词汇搭配 ～+名词 　～ authority　破坏威信 　～ bank　冲刷堤基 　～ confidence　丧失信心 　～ friendship　破坏友谊 　～ health　损害健康 　～ strength　削弱力气 句型例句 用作及物动词 ▲ S+～+n./pron. 　Rivers undermine their banks.　河水冲刷堤基。 　The soldiers undermined the wall.　士兵们在墙下挖洞。 　Badgers had undermined the foundations of the church.　獾在这座教堂的地基处打了洞。 　Illness undermined his strength.　疾病逐渐消耗了他的力气。 　Drugs undermined his health.　毒品损害了他的健康。 　Insults undermined her confidence.　一再受到侮辱之后，她渐渐丧失信心。 　She tried to undermine our friendship.　她试图破坏我们的友谊。 　These incidents could seriously undermine support for the police.　这些事件会严重影响对警方的支持。 　The President's enemies are spreading rumours to undermine his authority.　总统的敌人在散布谣言以逐渐破坏他的威信。 ◇ 用于be ～ed结构 　The house is unsafe since the foundations were undermined by floods.　这栋房子不安全，因为地基被洪水损坏了。 学习参考 　undermine　本身就含有“逐步”的概念，因此不能加gradually或suddenly来修饰。例如： 　 我的身体由于过去过分劳累而受到损伤。 误：My health was gradually undermined by overwork in the old days. 正： My health was undermined by overwork in the old days.
