    却说曹操正在军中,与诸将议事,人报徐州有战书到。操拆而观之,乃刘备书也。书略曰:备自关外得拜君颜,嗣后(嗣,sì。以后)天各一方,不及趋侍。向者,尊父曹侯,实因张(kǎi)不仁,以致被害,非陶恭祖之罪也。目今黄巾遗(niè,灾祸),扰乱于外;董卓余党,盘踞于内。愿明公先朝廷之急,而后私仇;撤徐州之兵,以救国难;则徐州幸甚,天下幸甚!曹操看书,大骂:“刘备何人,敢以书来劝我!且中间有讥讽之意!”命斩来使,一面竭力攻城。郭嘉(进谏,劝说)曰:“刘备远来救援,先礼后兵,主公当用好言答之,以(怠懈)备心,然后进兵攻城,城可破也。”操从其言,款留来使,候发回书。正商议间,忽流星马飞报祸事。操问其故,报说吕布已袭破(yǎn)州,进据濮(pú)阳。原来吕布自遭李、郭之乱,逃出武关,去投袁术;术怪吕布反覆不定,拒而不纳。投袁绍,绍纳之,与布共破张燕于常山。布自以为得志,傲慢袁绍手下将士。绍欲杀之。布乃去投张杨,杨纳之。时庞舒在长安城中,私藏吕布妻小,送还吕布。李傕(jué)、郭汜(sì)知之,遂斩庞舒,写书与张杨,教杀吕布。布因弃张杨去投张邈(miǎo)。恰好张邈弟张超引陈宫来见张邈。宫说(shuì,劝说)邈曰:“今天下分崩,英雄并起君以千里之众,而反受制于人,不亦鄙(被人轻视)乎?今曹操征东,兖州空虚;而吕布乃当世勇士,若与之共取兖州,霸业可图也。”张邈大喜,便令吕布袭破兖州,随据濮阳。止有鄄(juàn)城、东阿、范县三处,被荀或(yù)、程昱(yù)设计死守得全,其余俱破。曹仁屡战,皆不能胜,特此告急。操闻报大惊曰:“兖州有失,使吾无家可归矣,不可不亟(jí急)图之!”郭嘉曰:“主公正好卖个人情与刘备,退军去复兖州。”操然(同意)之,即时答书与刘备,拔寨退兵。

根据短文内容的理解,选择正确的答案。   

    Outside her shabby cottage, old Mrs. Tailor was hanging out laundry on a wire line, unaware that some children lay hidden in the leaves of a nearby tree watching her every move. They were determined to find out if she really was a witch.

    They watched as she took a broomstick to clean the dirt from her stone steps. But, much to their disappointment, she did not mount the broomstick and take a flight. Suddenly, the old lady's work was interrupted by the cackling of her hen—a signal that an egg had been laid in the warm nest on top of the haystack.

    The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty to keep up with the old lady. The cat provided proof—the children were sure that only a witch could own a black cat with three legs.

    There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking the egg in one of her hands, she began to climb down when, without warning, the box broke and the old lady fell.

    "We have to get and help her," whispered Amy.

    "What if it is a trick?" replied Ben.

    "Don't be silly, Ben. If she were a witch, she would have turned us into frogs already," reasoned Meg. "Come on, Amy, let's go." The girls climbed down the tree and ran all the way to the haystack.

    Approaching carefully, they could see a wound on the old lady's face. She had knocked her head on a stone and her ankle was definitely broken. "Go and get Dad," Amy yelled to her brother. "Tell him about the accident."

    The boys did not need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Tailor would not wake and turn the girls into frogs.
