absent的用法
1. 用作形容詞，表示“做某事缺席”，其后常接介詞 from：He was absent from school. 他沒有到校。有時根據(jù)不同的語境，也可能使用不同的介詞：John is absent because of his illness. 約翰因病缺席。He’s absent in Europe. 他外出了，現(xiàn)在歐洲。She was absent due to illness. 她因病缺席。不接介詞的用法：He was absent, as is often the case. 他缺席了，這是常有的事。The reason for his being absent remains a puzzle. 他為什么缺席是一個謎。An average of 10 students are absent each day. 平均每天有10個學生缺席。Each morning the teacher marks the pupils present, absent or late. 每天早晨老師給學生記出勤情況。
2. 用作動詞，是及物動詞，常接反身代詞作賓語。表示“做某事缺席”，其后也接介詞from：He absented himself from the meeting. 他開會缺席。
3. 點名時，若自己在場用 Here 或 Present (到，有)回答；若自己不在場，旁人可用 Absent (不在)回答。
4. 注意派生詞：absence n. 缺席，不在。表示“做某事缺席”，其后也接介詞 from：The teacher was angry at his absence from the meeting. 老師對他開會缺席很生氣。
