 ♣ in class A, of class A
　这两个短语的区别在于：in class A强调场所；of class A强调所属。例如：

 ♣ in class, in the class
　in class　表示“课内，上课时”，而in the class表示“在这个班级里”。例如：
　Try to speak as much English as possible in class.　课堂上尽可能多说英语。
　There are thirty students in the class.　这个班级有30个学生。
 ♣ class, order, rank
　这组词都可表示“集团”或“派别”的划分，“身份地位”或“等级”的“差别”。其区别在于：
1. rank一般指一个可以确定的“等级”，尤指“头衔”等；order指在社会中的某个阶层或某个结合紧密的社会性或职业性团体，尤指基督教某个等级的教士或团体；class主要指社会中持有同一个目的的一个社会阶层。例如：
　Even middle-class consumers in the U.S. are beginning to kick at the runaway prices.　连美国中产阶级的消费者也开始对飞涨的物价表示不满。
　He gained the rank of Colonel.　他获得了上校军衔。
　He is a member of the Order of the Garter.　他是获得嘉德勋位的爵士社团中的一员。
2. class还可指按经济地位、职能或按人们所具有的某些共同特征所做的划分。例如：
　This ticket doesn't entitle you to travel first class.　凭这张车票，你不能坐头等车旅行。
 ♣ class, course, lesson
　这三个词都有“课”的意思。其区别在于：class原指同一班级学习同一学科的人，由此可引申为同学聚集在一起“上课”; course指教学中一段时期内要教完或学完的功课，即“课程”; lesson指课程所分成的“段落”，课本中的“一课”或“每次授课的单位时间”。例如：
　There won't be any class today.　今天不上课。
　I took up a three-year course in English in middle school.　在中学，我学习了三年的英语课程。
　The new lesson is very difficult.　新课很难。
 ♣ 下面这句话有两个意思：

1. 全班在观点上有分歧。
　［误］ The class was divided in its opinion.
　［正］ The class were divided in its opinion.
　［析］ class是集体名词，当侧重整体时，谓语动词用单数形式；侧重个体时用复数形式。
2. 请在课后读几遍课文。
　［误］ Please read the text several times after the class.
　［正］ Please read the text several times after class.
　［析］ 表示“下课后”，应该说after class，在class前没有定冠词。
