Given the
relatively few restrictions governing access and usage, it is the
communications modal equivalent of international waters.请问老师modal
equivalent...是后置定语,中心词不是equivent吗?这是个名词不是形容词呀?
老师好,这里的句子是不是一种特殊用法they will have gotten through the psychological adjustments necessary to make it practical and sustainable, should they wish to continue.
Radiation from the sun,
space, and from communication devices on Earth are constantly bouncing around on the surface of the planet.
老师,这里主语明明是radiation,为什么使用复数谓语are?这是对的吗?
