［误］Sometimes my parents come to school to see me.
［正］Sometimes my parents come to the school to see me.
［析］有些名词被用作其本身原来所含目的时不加冠词，如：go to school上学，leave school(辍学)，after school(放学)，但如果当建筑物讲时应加冠词，如例句中其父母来校不是上学，而是看望孩子，则要加定冠词。又如，He was in hospital for two days.(他在医院住院两天了。)而：He went to the hospital to see his mother.他去医院看望他的母亲。

［误］The little boy wanted to go to cinema.
［正］The little boy wanted to go to the cinema.
［析］英语中虽有一些名词与go to连用时不加定冠词，以表示该名词的内涵，如：go to school (上学)，go to bed(睡觉)等，但去看电影则例外，要用go to the cinema.这也是语言的一个特点。
