Question

(2009宁夏银川模拟) In an experiment, pet owners are being encouraged to take their pets to work, a move _______ can be good for both the people and the pets.

   A. that some scientists say                            B. in which some scientists say

   C. some scientists say that                           D. some scientists say

Answer 1

A

解析:

根据对a move 到句子最后的这一部分分析，可以确定a move是先行词，同时是前面句子的同位语；而定语从句中缺少主语，因此排除B、D两项。关系代词要紧跟先行词，所以排除C，且此项的这种表达方式变成了宾语从句形式。
