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


  1. A.
    less; older
  2. B.
    less; elder
  3. C.
    fewer; older
  4. D.
    fewer; elder
A
句意:因為比舊機型節(jié)水、耗電量小,所以這臺洗衣機是環(huán)保的。water和electricity為不可數(shù)名詞,應由less修飾,故排除C和D。B項為干擾項,注意elder的用法:When comparing the ages of people, especially members of the same family, you can use both“older”and“elder”but never say“elder than”.如:my older/elder sister; the older/elder of their two children; My brother is older than me.
