anxious

1.这三个短语中, be anxious about和be anxious for两个短语较易混淆,其实他们的含义和用法都是不同的:be anxious about 表示的是“担心”的“内容”,而be anxious for表示的却是“渴望(得到)”的“目标”,试比较下面两个句子:

I am anxious about him.

我为他担心。

I am anxious for him.

我等着他。

有时宾语既是“担心”的“内容”,又是“渴望”(得到)的“目标”,则此时about和for可以通用。例如:

We were anxious about 〔for〕 her safety.我们盼望她平安无事。

从用法上说, anxious about后可接sth 也可接sb,而anxious for后一般只接sth,很少接sb。

2.be anxious at的意思是“因…而忧虑”, at的宾语是引起忧虑的“刺激源”,例如:

He was anxious at her absence.她的缺席使他忧虑不安。

这两个词都可表示“担心”“焦急”,它们的区别是：

anxious着重消极的“担心”或“焦急”, eager着重积极的“对成功的期望”“急于”或“进取的热情”,带有更多的焦虑情绪。例如:

The doctors are anxious about his health.医生们都担心他的健康状况。

He is eager about his studies.他对学习很热心。

He was very anxious that help should be sent promptly.

He was very anxious for help to be sent.

他渴望立即派人去救助。
