they will also be building new roads 在线等

问题1: they will also be building new roads also不是放实意动词前building 非实意动词be后的吗?
回答1： They will _A_ be _B_ building new roads _C_
下划线处均可放also，个人认为A/C更好
语法不佳，全凭语感

问题2: the Games will be held just outside the capital 这为什么有个just? 说明了什么? just不是出现在完成式中的吗? 这可是将来式啊?
回答2：如果你查字典，会惊讶地发现just有词条：used to emphasize what you are saying 表示强调。这种英文单词通常词义很多。

问题3:they will have finished work on the new stadium. 中 可不可以理解on the new stadium是介词短语修饰名词work的 定语?
回答3：按理这里work是名词，on the new stadium是修饰名词work的
因为finish此处用法：finish something/finish doing something

谢谢
不用谢

they will also be building new roads also
这里是用来修饰动词will 的

the Games will be held just outside the capital
just表示不偏不倚，正好在那儿的语气

they will have finished work on the new stadium.

on+名词表示工作的对象

also用于第一个助动词之后
just 强调
outside the capital
意为“就是”
应该是定语从句
they will have finished work "that&qu
