老师 您好 请问if和but可以出现在一个句子当中吗?
If we went by bus,it would be cheaper but the train is quicker.
If 从属连词引导we went by bus
But是并列连词,所以It would be cheaper but the train is quicker. 这句本应该就是完整的一个句子了,还可...
...ng.这是前面一个网友提问中的两个句子,请问 since
morning 可以不用冠词吗?比如说成:They have talked to him since the morning.They have been talking to him since the morning.https://www.cpsenglish.com/question/62793
