语法专题--介词
介词是一种虚词,它不能单独担任句子成分,必须与名词或代词或相当于名词的其他词类、短语或从句构成介词短语,才能担任句子成分。
· 知识点一:时间介词
1. 表示年、月、日、时刻等用at, in, on
· at 后常接几点几分,天明,中午,日出,日落,开始等。
· at breakfast / lunch / supper(在早餐时/午餐时/晚餐时)
· at noon/night/midnight(半夜) at sunrise(日出时) at dusk(黄昏) at dawn/daybreak (黎明)
· at Christmas at the beginning/end of last month at five o’clock(五点)
E. g: We will leave at daybreak.我们将在黎明时动身。
He drinks tea at breakfast.他在早餐时饮茶。
· on后常接某日,星期几,某周末的朝夕,节日等
· on Sundays / weekdays on Monday morning / afternoon / evening [用于星期、日期(包括该天的各部分)前]
【温馨提示】“在周末”既可以说at weekends,也可以说on weekends
· on a cold afternoon on the night of October 1, 1997 on the first day
· on Teachers’ Day on Christmas Day/Eve on National Day(用于公共节假日前)
【温馨提示】at,on都可用来表示“节假日”,但at侧重指“休假的时节”,而不是指具体的哪一天;on侧重指具体的时日,与它连用的短语中多含“Day”
at New Year(在新年期间) at Christmas (在圣诞节期间) on New Year’s Day(在元旦那天)
on Christmas Day (在圣诞节)
E. g: I often go fishing on/ at weekends.我经常在周末去钓鱼。
