        ①记不清是从哪天起,我回家,都要从一架扁豆花下过。
        ②扁豆栽在一户人家的院墙边。它们的藤蔓缠缠绕绕地长,你中有我,我中有你,顺了院墙,爬。顺了院墙边的树,爬。顺了树枝,爬。又爬到半空中的电线上去了。电线连着路南和路北的人家,一条人行甬道的上空,就这样被扁豆们诗意地搭了一个绿篷子,上有花朵,一小撮一小撮地开着。
        ③秋渐深,别的花且开且落,扁豆花却且落且开。紫色的小花瓣,像蝶翅。无数的蝶翅,在秋风里翩然舞蹈,欢天喜地。
        ④花落,结荚,扁豆成形。四岁的侄儿,说出的话最是生动,他说那是绿月亮。看着,还真像,是一弯一弯镶了紫色边的绿月亮。我走过时,稍稍抬一抬手,就会够着路旁的那些绿月亮。想着若把它切碎了,清炒一下,和着大米饭蒸,清香会浸到每粒大米的骨头里——这是我小时候的记忆。乡村人家不把它当稀奇,煮饭时,想起扁豆来,跑出屋子,在屋前的草垛旁,或是院墙边,随便捋上一把,洗净,搁饭锅里蒸着。饭熟,扁豆也熟了。用大碗装了,放点盐,放点味精,再拌点蒜泥,滴两滴香油,那味道,只一个字,香。打嘴也不丢。
        ⑤这里的扁豆,却无人采摘,一任它挂着。扁豆的主人大概是把它当风景看的。于扁豆,是福了,它可以不受打扰地自然生长,自然凋落。
        ⑥也终于见到扁豆的主人,一位整洁、干练的老妇人。下午四点钟左右的光景,太阳跑到楼那边去了,她家小院前,留一片阴。扁豆花却明媚着,天空也明媚着。她坐在院前的扁豆花旁,膝上摊一本书,她用手指点着书,一行一行地读,朗朗有声。我看一眼扁豆花,看一眼她,觉得他们是浑然一体的。
         ⑦此后常见到老妇人,都是那个姿势,在扁豆花旁认真地读书。视力不好了,她读得极慢。人生至此,终于可以停泊在一架扁豆花旁,与时光握手言欢,从容地过了。暗暗想,真人总是不露相的,这老妇人,说不定也是一个高人呢。像郑板桥,曾流落到苏北小镇安丰,居住在大悲庵里,春吃瓢儿菜,秋吃扁豆。人见着,不过一乡间普通农人,谁知他满腹诗才?秋风渐凉,他在他居住的厢房门板上,刻了一副对联“一帘春雨瓢儿菜,满架秋风扁豆花”。几百年过去了,当年的大悲庵,早已化作尘土。但他那句“满架秋风扁豆花”,却与扁豆同在,一代又一代,不知被多少人在秋风中念起。
        ⑧清代学者查学礼也写过扁豆花:“碧水迢迢漾浅沙,几丛修竹野人家。最怜秋满疏篱外,带雨斜开扁豆花。”有人读出凄凉,有人读出寥落,我却读出欢喜。人生秋至,不关紧的,疏篱外,还有扁豆花,在斜风细雨中,满满地开着,生命不息。

Title: Inner voice helps a lot throughout our lives.

    When you couldn't open your mouth till the first two years on the earth, inner voice helps you understand things. Inner voice always shows thoughts and ideas in the body.

    It justifies(判断) what is right and what is wrong. When we go against inner voice, we usually feel uncomfortable throughout our lives.

Sometimes when we are feeling sad, we seem to need some kind of support in spirit. We usually speak to our closest friend or our dearest family member during times of unhappiness to feel better. After talking to them, we suddenly feel active again, because our inner voice reminds us to get on with things and leave the things of the past in the memory.

    Inner voice is always right most of the time, because it knows us better than others and even ourselves. It's good to go by inner voice most of the time. Whenever you are trying to smoke, or whenever you are asked to choose one side in an argument, you are always worried about the result. During these times, your inner voice tells you what to do. If you don't follow your inner voice, you might be unhappy in the future. It's our own choice to either pay no attention to our inner voice or follow it and search for real happiness.
