n.（名詞）
Anxious has a long history of use roughly as a synonym for eager, but many would prefer that the distinction between the two words be maintained and thatanxious be used only when its subject is worried or uneasy about the anticipated event. In the traditional view, one may sayWe are anxious to see the strike settled soon but notWe are anxious to see the new show of British sculpture at the museum. Fifty-two percent of the Usage Panel rejectsanxious in the latter sentence. But general adoption ofanxious to mean .eager. is understandable, at least in colloquial discourse,since it provides a means of adding emotional urgency to an assertion,in its implication that the subject`s desire for a certain outcome is so strong that frustration of that desire will lead to unhappiness.Note, in this connection, the analogous use of sentences such asI`m dying to see your new baby in informal style.
Anxious 在很長一段時間以來，一直大致作為 eager 的同義詞來用， 但很多人喜歡保留這兩個詞之間的區(qū)別，即只有當主體對預(yù)測事件憂慮不安時才用anxious 。 在傳統(tǒng)觀點看來，可以說我們渴望看到罷工問題很快解決 ， 但不能說我們渴望在博物館里見到新的英國雕塑展覽。 52%的用法使用小組成員反對anxious 在后一個句子中的用法。 但通常用anxious 來表示.eager.是可以理解的， 至少在口語中是這樣，既然它加強了某一主張在感情上的迫切性，它隱喻的一層意思就是，主體對某一特定結(jié)果的愿望是如此強烈，以至于這種欲望受挫就會導(dǎo)致不愉快。注意與此有關(guān)的類似句子如我很渴望見到你們新出生的孩子 也是非正式的
