lesson课
lesson与class都有“课”的意思，两者在表示45分钟的“一节课”时是同义词，一般可以相互换用。
例句：今天我们有四节英语课。
We
have
four
English
lessons
(classes)
today.
Language
points
在以下情况下也有区别，两者不可换用：
1)当表示“第几课”时，习惯上用lesson而不用class。
例句：咱们读第一课吧。
Let's
read
the
first
lesson.
2)如果说“开始上课”，通常用class而不用lesson。
例句：上午8点开始上课。
Classes
begin
at
8:00
in
the
morning.
3)class还可以作“班级”，“同学们”，“阶级”讲，
而lesson无此意。
例句：我们学校有50个班级。
Our
school
has
fifty
classes.
Good
morning,
class!
同学们，早上好!
4)lesson可以作“功课”，“教训”讲，而class则不能。
例句：我能帮你学习功课。
I
can
help
you
with
your
lesson.
拓展：注意下列lesson和class的固定搭配：
do
one's
lessons做功课
give
lessons
to
给……上课
after(before)class课后(前)
in
class在课堂上
