Question

The view ______ many scientists hold is ______ too much emission of carbon dioxide is destructive.

A．what; that	B．that; which
C．that; that	D．which; which

Answer 1

C

试题分析：句意：许多科学家持有的观点是太多的二氧化碳的排放是有破坏性的。第一空是同位语从句，先行词是view，that在从句中不作成分；第二空是that引导的同位语从句，that在从句中不作成分。故选C。
点评：本题难度适中。同位语从句及表语从句都是属于名词性从句，that在从句中不作成分，只起连接的作用，但是此题同时考查了考生的分析复杂的句子结构的能力。
即学即练：Please put the medicine on the top of the shelf. It’s______  our children can’t reach it.
A.what       B.that         C.where        D.how
解析：C。句意：where引导表语从句，并在从句中作地点状语。
