Question

I have been meaning to talk to you.

 I have been meaning to talk to you是什么意思？是一句常用的口语吗？ We are supposed to be able to do our preparation and mark in that office.Jack constantly has students coming in to get help with his couse. 这两句什么意思？

Answer 1

I have been meaning to talk to you.
mean to 是“打算做”、“有意做”的意思，意思是：我已经在打算和你说话了也一直这么做着啊。
但我认为在口语中不太常用（可能吵架后会用，毕竟现在完成进行时这种复杂的时态实际口语中用得少）

We are supposed to be able to do our preparation and mark in that office.
be supposed to表示：应该 = should
我们应该可以在那间办公室做准备工作并作些标记。

Jack constantly has students coming in to get help with his couse.
have sb. do/doing 意思是：让某人做某事
杰克不断地让学生们进来帮助他课程的学习。

Answer 2

1.have been meaning 这是现在完成进行时，表示一个动作到现在为止已经持续了一段时间，还有可能继续持续下去。
I have been meaning to talk to you。我一直想和你谈谈。（现在见到你了，正好谈谈，要不我就要一直想下去了，O(∩_∩)O~）
再如：It has been raining for a whole week.已经落了整整一个星期的雨了。（还没停，好像还要继续落下去的样子。）
2.We are supposed to be able to do our preparation and mark in that office，我们应该可以在那间办公室做准备和打分。
3.Jack constantly has students coming in to get help with his course.杰克时常让学生进来，好帮他们学习他的那门课程。
have sth\sb doing 让.......一直.......
例：He has the horse running all the way.他让马一路跑过来。
help..sb..with..sth. 在某方面帮助某人

Answer 3
