Notes注释
1When you ask about something that started in the past but continues to the present time， you use the Present Perfect tense，e.g.： How long have you lived in Beijing？
/ How long have you lived in Beijing？； I have been here for seven years / I have been here for seven years.当你批评辩论从过往开始不断继续到现在的某件事时，用现在完成法时态。例如：How long have you lived in Beijing？ /你在北京住了多久了？；I have been here for seven years /我在这里已经七年了。
2If you are talking about something that is completely in the past，you use the Past Tense（sometimes called the Imperfect），e.g.： Before I came to Beijing， I worked in Shanghai / Before I came to Beijing I worked in Shanghai.如果批评辩论的事变完全发作在过往，则用过往时态（偶尔也叫做未完成时态），例如：Before I came to Beijing， I worked in Shanghai /在来北京之前，我在上海义务。
3Usually when you talk about your birthplace or year of birth，you use the Past Tense， e.g.： I was born in Shanghai / I was born in Shanghai； I was born in 1977 / I was born in 1977.在批评辩论出生地大概出生年份时，每每用过往时态，例如：I was born in Shanghai /我出生在上海； I was born in 1977 /我出生在1977年。
