1.can you give us more examples,要用复数,example是可数名词
2.grace likes chemistry best at school,Grace是第三人称单数,动词后面要加s
3.she was having a conversation with our teach,conversation不可数,have a conversation是固定搭配,谈话的意思
4.除了我、你、他们以外的个人都是第三人称单数
5.are the old people siting under the tree you parents.people单复同形,只能用are,而且后面说了是parents,是复数
1.不可数
