关于until和when的选择题
是一道完形填空,里面有一段是
When all the seats were taken,the driver started the engine.The conductor began to collect fares.When she came to an old man in worn-out clothes,he explained that he had spent all his money when he had accidentally got on a wrong bus and now he was trying to go home.On hearing this,she ordered the old man to get off the bus.The old man was almost in thears as he begged her to let him take the bus home.The driver took the conductor's side and repeated the conductor's command.
The woman was watching the incident.(________)the driver and the conductor raised their voices at the old man,she interfered.
上面这个括号里应该选择 When 还是 Until呢?2个好像都可以,但是标准答案说是when.
关于until和when的选择题是一道完形填空,里面有一段是When all the seats were taken,the driver started the engine.The conductor began to collect fares.When she came to an old man in worn-out clothes,he explained that he had spent all
这里不能用until,只能用when.until的意思是直到...才（改变原有的状态）的意思.这个句子如果改成The woman had been watching the incident (________)the driver and the conductor raised their voices at the old man.则需要填上until.注意原题中The woman was watching the incident已经放在另一个句子中了.
until一般和not或no连用，例如是 People didn't find that kind of animals until 19th century.
在这里Until the driver and the conductor raised their voices at the old man, she did no notice him.
这里选when更为合理。
可以根据翻译意思来看
要用when不能用until。因为interfere是一个短暂性动词，不能延续。
