Question

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

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。
