译文：大约用了8天
an 8-day! 因为eight就是元音因素开头的!所以前面只能用an.18,80,...前面也用an 11 前面也用an ,eleven也是元音因素开头!
倒计时: Count downTen days to go ...Nine days to go ......One day to go ...比如说：Ten days to go before the open ceremony of the Olympic Games.Only one day left to the open ceremony of the Olympic Games.
The countdown, and ten days, nine days, eight days, seven days, six days, five days, four days, three days, two days, a day.
an 8-day trip因为 8 的发音是 /eit/，开头是元音 /e/。发音是元音开头的用 an，是辅音开头的用 a。
