7月23日出发8月12日回到家里旅游了几天?

20分+20分=40分，
18时10分-40分=17时30分，
17时30分-12时=5时30分，
答：他们最晚要在下午5时30分从家里出发才不会误火车．

解题思路：小明从家到火车站要20分钟，再加上火车提前20分钟检票，小明必须提前出发的时间是20+20=40分钟，又知道是7月23日18：10从广州至北京的火车票，要求他们最晚要在下午几时几分从家里出发才不会误火车，用火车出发时刻18时10分减去提前出发的时间40分，然后化成普通计时法，即可得解．

20分+20分=40分，
18时10分-40分=17时30分，
17时30分-12时=5时30分，
答：他们最晚要在下午5时30分从家里出发才不会误火车．

12÷4=3
都能除净,所以7月23日加上12=八月四号

　　中国共产党第一次全国代表大会正式开幕的时间是1921年7月23日,一大召开标志着中国共产党的正式成立.所以,中国共产党正式成立的时间应该是1921年7月23日.
　　把7月1日作为党的诞生纪念日,是毛泽东于1938年5月提出来的.当时,毛泽东在《论持久战》一文中提出：“今年七月一日,是中国共产党建立十七周年纪念日.”这是中央领导同志第一次明确提出“七一”是党的诞生纪念日.
　　当时在延安的曾经参加过一大的党的创始人只有毛泽东、董必武两人.他们回忆一大是7月份召开的,但记不清楚确切的开会日期.因为缺乏档案材料,一时无法查证,所以就把7月1日确定为党的诞生纪念日.
　　“七一”作为党的诞生纪念日,最早见于中央文件是1941年6月.当时,中共中央发出《关于中国共产党诞生二十周年、抗日四周年纪念指示》.《指示》说：“今年七一是中共产生的二十周年,七七是中国抗日战争的四周年,各抗日根据地应分别召集会议,采取各种办法,举行纪念,并在各种刊物出特刊或特辑.”这是以中共中央名义作出的把“七一”作为党的诞生纪念日进行纪念的第一个文件.
　　党的一大开幕日期到20世纪70年代末才由党史工作者考证清楚,根据新发现的史料和考证成果,确定一大的召开日期是1921年7月23日.
　　虽然党的诞生纪念日并不是党的一大召开的具体日期,“七一”这个光辉的节日已经深深地铭刻在全党和全国各族人民的心中.它成为人们每年进行纪念的一个重要节日.

If Everyone Cared 如果每个人都学会关心
From underneath the trees, we watch the sky 在树下仰望天空
Confusing stars for satellites 化成点点繁星

Singing Amen, I'm alive 一起祈祷,我仍然活着
Singing Amen, I'm alive 生命是如此美好
If everyone cared and nobody cried 如果每个人都学会关心,那就没有人哭泣
If everyone loved and nobody lied 如果每个人都学会爱,那就没有欺骗
If everyone shared and swallowed their pride 让我们分享荣耀
We'd see the day when nobody died 我们将看不到死亡
And I'm singing 让我们高歌
Amen I..., I'm alive 一起祈祷,生命如此美妙
And in the air the fireflies 夜空中的萤火虫
Our only light in paradise 是通往天堂的明灯
We'll show the world they were wrong 让世人抛却烦恼
And teach them all to sing along 随我们一起歌唱
Singing Amen I'm alive 生命是如此美好

If everyone loved and nobody lied 没有欺骗
If everyone shared and swallowed their pride 一起分享荣耀
We'd see the day when nobody died 没有死亡

And as we lie beneath the stars 我们躺在星空下
We realize how small we are 是如此的渺小
If they could love like you and me 如果世人能够像我们一样相爱
Imagine what the world could be 会把世界唤醒
If everyone cared and nobody cried 如果每个人都学会关爱
If everyone loved and nobody lied 那就没有哭泣与谎言
If everyone cared and nobody cried 没有悲伤
