a / an / the / no article
冠词训练器：先判断，再练习，再迁移
1. Quick Start
Which article do we need?
先判断：这里需要哪个冠词？
什么时候用？
表示一个单数可数的人或物，通常是第一次提到，或者还不具体是哪一个。
Examples: a school, an idea
什么时候用？
双方知道具体是哪一个，或者前面已经提到过。
Examples: a dog → the dog, a school → the school
什么时候不用冠词？
泛指复数名词或不可数名词时，通常不加冠词。
Examples: students, water, homework
有些表达加不加 the，意思会改变。
go to school = 去上学
go to the school = 去那所学校
后面会专门练习这类区别。
