树形笔石的胞管可分为()、()和()三种类型。
李李氏,女,生于1899年,居于山东省青岛市。 年过百岁的李李氏老人非常喜欢聊天,她将聊天当成生活的一部分。 与人聊天时,她将许多生活中的忧愁和烦恼之事痛痛快快地“一说了之”,不再为这些忧愁和烦恼浪费精力。 她将聊天当作家庭和睦的一剂良方,每当女儿与孙子闹意见时,她总是借聊天在女儿和孙子之间调解撮合。 老人说,聊天或许就是她的长寿秘诀。与家人聊天时,她感受亲情;和邻居唠嗑时,她感受温暖;和晚辈攀谈时,她感受童心。 除了聊天之外,老人的另一个长寿心得,恐怕莫过于动与静的完美结合了。 老人好动也好静,耄耋之年的时候,即便腿脚不便,她也总是拄着拐杖出门溜达,看路边的光景。出门之时,老人总是随身带个小马扎,走累了,便打开马扎,坐在上面晒太阳,休息好了再起来走动。及至百岁,外出下楼,她也不肯让家人搀扶,执意自己行走。 如今年事已高,不便行走,呆在家中无事,她便自创了一套坐功。她经常坐在床上或是椅子上,连续两三个小时不动,一天常常能坐上近10个小时。如此静坐后,老人的睡眠质量特别好,每晚一躺到床上,便能很快进入梦乡。 |

A.暴躁
B.温柔

D.沉稳
