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：

句中water和electricity為不可數名詞，可排除含有fewer的C、D項；elder意為“年長的”，older意為“年老的；舊的；從前的”，所以第二個空應選older，表示“老式的”。
