According to the recent regulation, it is required that any chemical plant that_______ along the river _______ to build a recycling center for the waste.
A．locate; has
B．locates; have
C．is located; have
D．is located; has
答案
答案：C
句意“根据最近的规定，任何沿河修建的化工厂都不得不建一个垃圾循环中心。”that引导的是定语从句，从句缺少谓语部分，be located in...是固定搭配，意为“坐落于......”。这里的along是介词，意为“沿着”。require“要求”，后面的同位语从句应该用should+动词原形，should可省略。故选C。
