at the time 可以做连词用吗
he became a doctor （by） the time he is 31.by那个空可以填at吗

不是连词,是介词短语.
可以,不过is要写成was
再问：不可以做连词就应该不填at把因为at the time不能连接两个句子啊填at的话应该是at the time when he was 31，后为一个定从，是吗？

at the time 可以做连词用吗连词成句Englishi.is.at.the.difficult.time.exam.realy.连词成句最好可以说说做连词时到底用the next time 还是 next time we had a great time at the picnic的at可以写成in吗 suddenly可以做连词吗介词可以做连词吗? then可以做连词吗? at the time、at that time与at this time的语用含义 all ,the,why,time,me,the,looking,is,man,at 连词成句 what time is it?答语可以是at seven o clock in the morning.吗? meanwhile和at the same time 可以像when 一样放在句中用吗 look at the time
