Could you help me with these sentences?
1.The waitress will be back.
Why use "will be"? What's the differences between "will be back "and "wii back"?
2.…, as well as the mounting pressure as the deadline for that first assignment creeps up on you.
What' s the meaning of "as" in the middle of this sentence? Does it mean "like" or "accompany"? How to distinguis these two meanings?
3.Finally,we won all but just one of the twelve appeals that we launched on behalf of students.
I have no idea of what's this sentence meaning? Could you help me with this?
Thank you in advance.
