"在接下来的几节课中" 英语怎么说啊?

这里的课应该是课堂吧，如果是指课堂，应该用class，而不是lesson，lesson指的是课本中的几课，或者几章，几个单元

in the several classes that followed

in the several following classes

另外，在美国，一般不用classes，而用 hours，因为一节课一般为一小时，所以说

in the following few hours

In the next lessons

In the following lessons

during the following lessons/classes

in the following lessons.
during the following lessons.
in the next lessons
