    卓茂字子康，南阳宛人也。性宽仁恭爱。初辟丞相府史，时尝出行，有人认其马。茂问曰：“子亡马几何时？”对曰：“月余日矣。”茂有马数年，心知其谬，默解与之，挽车而去，顾曰：“若非公马，幸至丞相府归我。”他日，马主别得亡者，乃诣府送马，叩头谢之。

    后以儒术举为侍郎，迁密令。劳心谆谆，视人如子，举善而教。人尝有言部亭长受其米肉遗者，茂辟左右问之曰：“亭长为从汝求乎？为汝有事嘱之而受乎？”人曰：“往遗之耳。”茂曰：“遗之而受，何故言邪？”人曰：“窃闻贤明之君，使人不畏吏，吏不取人。今我畏吏，是以遗之，吏既卒受，故来言耳。”茂曰：“汝为敝人矣。凡人所以贵于禽兽者，以有仁爱，知相敬事也。今邻里长老尚致馈遗，此乃人道所以相亲，况吏与民乎？吏顾不当乘威力强请求耳。汝独不欲修之，宁能高飞远走，不在人间邪？亭长素善吏，岁时遗之，礼也。”人曰：“苟如此，律何故禁之？”茂笑曰：“律设大法，礼顺人情。今我以礼教汝，汝必无怨恶；以律治汝，何所措其手足乎？”于是人纳其训，吏怀其恩。数年，教乃大行，道不拾遗。时光武初即位，乃下诏曰：“前密令卓茂，束身自修，执节淳固，诚能为人所不能为。今以茂为太傅，封曪德侯。”

    论曰：卓茂断断小宰无它庸能而首加聘命优辞重礼，其与周燕之君表闾立馆何异哉？夫厚性宽中近于仁，犯而不校邻于恕，率斯道也，怨悔曷其至乎!

    Outside her cottage, old Mrs. Taylor was hanging out laundry on a wire line, unaware that some children were hiding in a nearby tree watching her every move. They were determined to find out if she really was a witch.（女巫）

    They watched nervously as she took a broomstick(长柄扫帚）to sweep the dirt from her stone steps. But much to their disappointment, she didn't get on the broomstick and fly off. The old lady only looked up when her hen began to make sounds loudly —signaling that she had laid an egg in the nest on the top of the haystack.(干草堆).

    The old lady put aside her broomstick and walked to the haystack, followed by Michael, a black cat she had rescued from a fox trap. With only three legs, it was hard for Michael to keep up with his mistress. The cat was proof for the children that only a witch would own a black cat with three legs! Crawling further along the branches, they could clearly see the haystack.

Mrs. Taylor was standing on a wooden box with the new-laid egg in one hand. Placing the egg in her pocket, she readied herself to climb down. Then, without warning, the box broke under her and she crashed to the ground. The children were in horror.

“Should we go and help her?” asked Mia.

    “What if it's a trick?” replied Patrick. “She probably knows we're here. Witches know things like that!”

After thinking for a while, Julia said “Anyway, we should go and check whether she is all right.”

Approaching prudently, they could see a wound on the old lady's forehead. She had knocked her head on a stone and was unconscious.

“Go and get Dad,” Mia yelled to her brothers. “Tell him about the accident.”

The boys didn't need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Taylor would not regain consciousness and turn the girls into frogs.

    Later, in the hospital, the old lady smiled her thanks. “I was so lucky that you lovely children happened to be passing when 1 fell. I must have yelled quite loudly.”

    The children exchanged guilty glances, but were very pleased that she was not a witch after all!
