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 speculation：I have a speculation that it will rain tomorrow. → I have a feeling that it will rain tomorrow. (speculation通常不用于个人主观感觉，而指基于不完整信息的猜测；日常场景中可用feeling或guess代替。)
