 ♣ careful, attentive, cautious, precautious
　这组形容词都有“细心的”“谨慎的”意思。其区别在于：
1. careful修饰具有动作概念的名词时，可译为“细致的”“精心的”，含有靠认真实践来避免错误的意味。例如：
　One can never be too careful in his work.　工作越细心越好。
　She was careful enough to find this mistake of mine.　她相当仔细，发现了我的这一差错。
2. attentive指为了理解或改变事物而采取“注意的”或“聚精会神”的态度，有时含有谦恭有礼的意味。例如：
　Please be more attentive to your studies.　请多用点儿心读书。
　A speaker likes to have an attentive audience.　演讲者喜欢聚精会神的听众。
　She was very attentive to her sick sister.　她非常关心生病的妹妹。
3. cautious指对待某事物时，要仔细考虑各种可能性，所持的态度是“细心的”“谨慎的”，含有要避免危险、谨慎留意、以防出现差错的意味。例如：

　He is a cautious driver.　他开车很谨慎。
　Papa, intensely cautious, never made a decision lightly.　爸爸非常谨慎小心，从来不轻易作出决定。

4. precautious指对待某事物是“有防备的”“戒备的”“警惕的”，尤指社会场合的谨慎，除非对知己者，否则不愿对他人谈及自己的个人问题，也指担心出差错而事先做好各种防范准备。例如：
