at school/ in school/ in a (the) school Ⅰ. at school表示在学校、在上学相对于在家里或在校外。如: ① My son is at school now. He is not at home or somewhere else. 我儿子现在在学校,他不在家,也不在别的地方。 ② When my brother was at school, he studied very hard. 在学校时,我兄弟学习很用功。 Ⅱ. in school 在求学、在上学相对于有工作。如: My daughter still in school She doesnt work. 我女儿还在上学,她不在工作。 [注]:①和②用at school 强调所在场所或时间。 ③中的in school 则强调主语的身份是学生。因此,in school. 和 at school的着重点不一样,通常不互换使用。 Ⅲ. In a / the school 在学校,不一定指上学。类似的还有: in hospital 生病住院 in a / the hospital表在医院(工作或探视病人等) at table 在吃饭 at a / the table 在桌边(有可能在聊天或看报) ① Is your friend in school? 你的朋友在上学吗? ① Your friend looked for you in the school just now. 刚才你的朋友在学校里找你。 ② Children are often in hospital when they are young. 孩子们小的时候经常生病住院。 |
