at class在班上
例句:Steve learned a lot at class.
史蒂夫在课上学会了很多。
in class
在课堂上;上课中
例句:In class, he practices English with his teacher and classmates.
在课堂上,他跟他的老师和同班同学们练习英语。
扩展资料:

n. 阶级;班级;种类;班;等级
vt. 分类;把…分等级;把…归入某等级,把…看作(或分类、归类);把…编入某一班级
adj. 极好的;很好的,优秀的,出色的
vi. 属于…类(或等级),被列为某类(或某级)
过去式: classed 过去分词: classed 现在分词: classing 第三人称单数: classes
class用作动词的意思是“把…归入某等级”,是及物动词,接名词或代词作宾语;class也可表示一节具体的“课”,是可数名词。也可抽象化,表示“上课”这一概念,这时class是不可数的,其前不用定冠词。

六、in class 和of class的区别?
1、含义不同
in 如果说是方位介词,指在内部,里面。of 当介词“的”讲,a map of China
2、范围不同
in是指一个广泛的范围,像in the world,in the class
of是对应的范围,像of the three people
例子
He is the tallest boy in my class.(he属于class)
He is the tallest of these boys.(boys和he是对应的,he就是boy)
in the front of和in front of的区别:
区别是什么
1、in front of 与 in the front of 用法不同,前者表示“在……前面”,指范围之外的前面,后者表示“在……的前部”,指范围之内的前部。比较:
There’s a bus stop in front of the school.学校前面有个公共汽车站。(范围之外)
I prefer to travel in the front of the car.我喜欢坐在汽车的前面。(范围之内)
2、而at the front of的用法比较广,它不仅兼有以上两个短语的意思和用法,而且还有其他一些用法。如:
We’ll try to get seats at the front of the hall.我们要设法弄到大厅前面的座位。(范围之内)
At the front of the book is a table of contents, giving details of what is in the book.书的前部有目录,详列了书中的内容。(范围之内)
He planted some trees at the front of the house.他在房子前面种了些树。(范围之外)

九、the class 和class的区别?
一、指代不同
1、class:在上课。
2、the class:在课堂上。
二、语法不同
1、class:class也可作“班级”解,是可数的集合名词。可作单数使用,也可作复数使用,在美式英语中作单数用得更多些。作单数使用时,表示一个中性的无生命的整体,要用it或which来指代,谓语动词要用单数形式。
2、the class:class也可表示一节具体的“课”,是可数名词。也可抽象化,表示“上课”这一概念,这时class是不可数的,其前不用定冠词。
三、侧重点不同
1、class:表示一种状态。
2、the class:表示一个位置。
十、on class和in class的区别?
"On class" 意为“其他类中调用本类(或本类的静态成员)”,而 "in class" 则指在类定义内部使用成员。
具体来说,当在一个类的外部想要调用该类的非静态成员时,需要使用该类的对象来访问这些成员,这个过程称为 "on class",例如:
```
class MyClass {
public:
int member;
};
MyClass obj; // 创建 MyClass 对象
obj.member = 42; // 访问 MyClass 对象的 non-static 成员变量
```
而当在类定义内部声明和定义成员时,可以直接使用成员名字来访问成员。这个过程称为 "in class",例如:
```
class MyClass {
public:
int member;
void doSomething() {
member = 42; // 直接访问 MyClass 的成员变量
}
};
```
总之,在类定义的范围内,可以直接使用成员名称访问成员变量和函数,这被称为 "in class"。当在相同类之外调用类成员时,必须按照该类的规则进行访问,这被称为 "on class"。
