常见误用提醒
使用 overinvestment：He made an overinvestment in the company. → He made overinvestment in the company. (overinvestment 是不可数名词，通常不加冠词 'an'，直接使用即可。)
使用 overinvestment：The overinvestment caused the economy to grow slowly. → The overinvestment caused economic problems. (overinvestment 通常与负面结果如问题、风险或危机相关，而不是缓慢增长；应使用更准确的搭配如 'economic problems'。)
使用 underinvestment：The underinvestment of the project caused delays. → Underinvestment in the project caused delays. (错误在于使用了'of'，而'underinvestment'通常与'in'连用表示在某个方面的投资不足；应改为'in'以符合习惯搭配。)
