Question

1.These boys need to have their hair cut.为何不能是hairs cut 这不是已经特指了这些男孩了么 hairs cut为何错
2.I don't like wearing long hair.为何不能是 a long hair.
3.He gained experience in dealing with such people.为何不能是experiences,对付这些人的经验,我始终认为是复数,谁快来帮我解答下来说服我~
4.I opened the letter and it contained an important piece of information.这句我有一点不明,既然information在这里用piece of修饰,就是说这词不可数,那为什么不可数前面还要有an important "an"我记得老师说过不可数名词不能用a(an)修饰.

Answer 1

hair 不可数名词

hair 不可数名词

experience 用作经历是可数名词 用作经验是不可数名词

an important piece of information中an修饰的是piece 本来是a piece 因为有important所以是an
