请问1.she (had lost )her job and (was working) as a waitress
2.“what were you doing when Anna phone you ” “i（had finishe )my work and (was started )to take a bath" 这俩天括号里为什么它们用的时态不是一致的 3.Even though Tom （had been studying） Chinese for three years before he came to China,it is still difficult for him to express himself 4.my friend has returned from the UK.She （studied） at Oxford for four years ,during which time we communicated with each other on the Internet 第三题用的是过去完成进行时,第四题用的是过去进行时!它们加后面不是都是加了时间点嘛!也就是for后面的时间!可它们用是时态却不一样
