Question

This washing machine is environmentally friendly because it uses ________ water and electricity than ________ models．

[　　]

A．

less; older

B．

less; elder

C．

fewer; older

D．

fewer; elder

Answer 1

答案：A
解析：

water和electricity为不可数名词，应由less修饰，故排除C和D项。older常常作定语修饰一个家庭里(有血统的)较年长的人。older可以作定语和表语，意思是“较旧的，较年长的”，修饰人或物。语意为：因为比旧机型节水、耗电量小，所以这台洗衣机是环保的。
