"lack of" 是名词短语,核心是名词 lack(缺乏;不足),整体表示“缺乏;没有;不足”,用来指代“某事物的缺失或数量不够”。
"lack of" 后接名词/动名词(即被“缺乏”的对象),主要作主语、宾语或介词宾语,常见搭配如下:
结构:Lack of + 名词 + 谓语
例:
Lack of sleep can cause irritability and poor concentration.(缺乏睡眠会导致易怒和注意力不集中。)
Lack of communication is often the root of relationship problems.(缺乏沟通往往是关系问题的根源。)
常见动词:have, suffer from, experience, face, feel, complain about 等
结构:动词 + (a) lack of + 名词
若强调“具体某种程度的缺乏”,可加不定冠词 a(此时 lack 可数);
若泛指“整体缺乏”,不加 a(lack 不可数)。
例:
Many children in poor areas suffer from a lack of nutritious food.(贫困地区的许多孩子缺乏营养食品。)
She has no lack of confidence—she just needs more practice.(她不缺乏自信——只是需要更多练习。)

lack 既可以作名词(搭配 of),也可以作及物动词(直接接宾语,无需 of),注意区分:
动词用法:sb/sth lacks sth(某人/某物缺乏某物)
例:He lacks experience.(他缺乏经验。)= He has a lack of experience.
名词用法:lack of sth(缺乏某物)
例:Lack of experience makes it hard for him to find a job.(缺乏经验让他难找工作。)
lack of time 没时间
lack of money 缺钱
lack of motivation 缺乏动力
lack of support 缺乏支持
lack of education 缺乏教育
总结:"lack of" 是名词性短语,核心是“缺失某事物”,需后接名词;若作动词用,则直接接宾语(无 of)。掌握其与动词的区别,就能准确使用啦!
