同近义词辨析

critical, crucial, urgent, acute

这组词都有“严重的，重要的”的意思，其区别是：

criticala.意为"关键的"，表示处于极度缺乏的状态或事件的转折点，与crucial相似。

与crucial的区别在于它对缺乏的或危急的程度有更准确的衡量；还指"批判性的，分析性的"。

It is critical that you study hard for the exam or you will fail it.为了考好你必须用功学习，则你会不及格的。

cruciala.意为"决定性的，紧要关头的，至关重要的"，最为笼统，适用于上述两种情况。

Improved consumer confidence is crucial to an economic recovery.消费者信心的增强对经济的复苏是至关重要的。

urgenta.意为"紧迫的，急迫的，紧要的"，它不强调所指的问题是最重要的，仅强调"紧急的"状态。

We have an urgent need for help; we are running out of water.我们急需要帮助，我们的水就快要用光了。

acutea.剧烈的，严重的；急性的(病)。

An acute lack of food brought hunger to the Iraqi people.食品严重缺乏，伊拉克人民正在忍饥挨饿。
