名词:单数、复数与所有格

大多数名词加-s构成复数,但有些是不规则的(child → children, person → people)。可数名词可以计数(one apple, two apples);不可数名词不能(water,而不是"a water")。给名词加's表示所有格。

Examples

• I have two children and one dog.
• There is a lot of water in the bottle.
• This is Sarah's book.
• London is a big city. It is in England.
• The women are talking to the teacher.
