"have a class"是英语中高频日常短语,核心含义与“课程安排”相关,以下是详细解析:
最常见的意思是:上课;有课(既可以指学生参与课程,也可以指老师讲授课程,强调“有课要上”的客观状态)。
学生视角(“要去上课”):
I have a class in 5 minutes—I need to run!(我5分钟后有课,得赶紧走!)
老师视角(“要去讲课”):
Ms. Lee has a class with the 9th graders this afternoon.(李老师今天下午要给9年级学生上课。)
常与科目、时间、地点连用,让表达更具体:
搭配科目(what class):
We have a biology class every Wednesday.(我们每周三有生物课。)
搭配时间(when):
Do you have a class at 3 p.m. today?(你今天下午3点有课吗?)
搭配地点(where):
They have a class in the new lecture hall.(他们在新报告厅上课。)
have a class:侧重“一节具体的课”(单数表“某一次/某一节”);
have classes:侧重“多节课”(复数表“常规的、连续的课程”)。
例:
She has classes from 8 a.m. to 12 p.m.(她上午8点到12点有课。)(多节)
I have a class on Friday afternoon.(我周五下午有一节课。)(一节)
Hurry up! We have a class in 10 minutes.(快点!我们10分钟后有课。)
The teacher doesn’t have a class tomorrow.(老师明天没课。)
Do you have a class with Mr. Brown this semester?(你这学期有布朗先生的课吗?)
have a class:强调“客观有课”(课程是安排好的);
take a class:强调“主动修课”(自己选择参与的课程)。
例:
I’m taking a cooking class this year.(我今年在上烹饪课。)(主动选择)
I have a cooking class every Thursday.(我每周四有烹饪课。)(客观安排)
teach a class:仅用于老师,明确“教某节课”;
have a class:可用于老师或学生,强调“有课要上”的状态。
例:
The teacher teaches a class of 30 students.(老师教一个30人的班级。)(明确“教”)
The teacher has a class at 2 p.m.(老师下午2点有课。)(强调“要上课”的状态)
偶尔可表示“拥有/管理一个班级”(侧重班级的归属),但需结合语境判断:
The new teacher has a class of very active students.(这位新老师有一个很活跃的班级。)
"have a class"是日常场景(学校/培训机构)中最常用的“上课”表达,核心是“有课要上”,适用学生和老师,常搭配时间、地点、科目,需注意单复数和相似短语的细微区别。
