【辨析】 since与for
①since意为“自……以来”,所表示的是一个时间点,既可作介词,后接时间名词或短语;也可作连词,引导时间状语从句,前面的谓语动词或主句的谓语动词必须是延续性的且句子用完成时态,从句用一般过去时态。如:
Mr. Brown has worked in that factory since 1998.
自1998年以来,布朗先生就在那家工厂工作了。
I have been collecting stamps since I was five years old.
我自五岁起就一。直在收集邮票
②for作介词,后面接时间段,多用于完成时态,句中的谓语动词用延续性动词。如:
They have waited for the moment for many years.
【拓展】对since短语或从句及for短语提问用how long。如:
Lucy has been swimming since she was 10.(对划线部分提问)
How long has Lucy been swimming?
