We had been in the city not more than two days until we found that we needed a guide. This is a sentence and there is a mistake in it. I feel the word "until" is inappropriate in this sentence, but i can't find a word to replace it. Please give me the answer if you know. Thank you for your help. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 180.177.116.25
