brain
1.说“脑”用brain,说“脑髓”用brains,说“智力”用brain或brains都可以。注意下面几个习语:
suck(或pick)his(或your等)brain(s)(剽窃他[或你等]的脑力劳动成果,用brain或brains都可以),
have no brain(s)(没有智力,用brains普通些),
cudgel my(或your等)brains(绞脑汁,该用brains),
rack my(或your等)brain(s)(绞脑汁,用brain或brains都可以),
have on the brain(痴想,该用brain),
turn his(或your等)brain(使他[或你等]失态,该用brain)
2.much brains(许多智力)和little brains不可改作many brains和few brains。
3.注意He has a marvellous brain等句子里有a。可以说Two brains(两个人的智力)are better than one。
