acquirement
1.说“学识”习惯用复数形式，如intellectual acquirements和literary acquirements。
2.acquirement和acquisition不同。两个单词都有“得到”和“所得到的东西”两个意思，但acquirement总是指精神上的，acquisition却指物质上和精神上的都可以。例如：
- the acquirement of knowledge, his literary acquirements,
- the acquisition of property, the acquisition of skill,
a great acquisition to the hospital, his mental acquisitions
