John was waiting for the girl whose heart he knew,but whose face he didn’t,the girl with the rose.Thirteen months ago,in a Florida library he took a book off the shell and found himself interested in the notes in the margin(页边).The soft handwriting showed a thoughtful soul and insightful(有洞察力的)mind.

In front of the book,he discovered the name,Miss Hollis Maynell. With time and effort he got her address.He wrote her a letter introducing himself and inviting her to keep in touch.  

During the next year and one month the two grew to know each other through the mail. A romance started.John requested a photograph,but she refused.She felt that if he really cared, it wouldn’t matter what she looked like.Later they agreed on their first meeting—7:00 pm at Grand Central Station in New York.

“You’ll recognize me,” she wrote,“by the red rose I’ll be wearing my coat.” So at 7:00 he was in the station looking for the girl with the red rose.

A girl in a green suit was coming toward him,her figure long and slim and her eyes were blue as flowers.Almost uncontrollably he came to her,and just at this moment he saw Hollis Maynell—a woman well past 40.The girl was walking quickly away.

He did not hesitate(犹豫),saying,“I’m John,and you must be Miss Maynell.I am so glad you could meet me. May I take you to dinner?”

The woman smiled, “I don’t know what this is about,son,” she answered,“but the young lady in the green suit begged me to wear this rose on my coat.And she said if you were to ask me out to dinner,I should tell you that she is waiting for you in the restaurant across the street.She said it was some kind of test!”

狱中上母书(1)

夏完淳 

  不孝完淳,今日死矣!以身殉父(2),不得以身报母矣!痛自严君见背,两易春秋。冤酷日深,艰辛历尽。本图复见天日,以报大仇,恤死荣生,告成黄土。奈天不佑我,钟虐明朝,一旅才兴,便成齑粉。去年之举,淳已自分必死,谁知不死,死于今日也!斤斤延此二年之命,菽水之养,无一日焉。致慈君托迹于空门,生母寄生于别姓,一门漂泊,生不得相依,死不得相问。淳今日又溘然先从九京,不孝之罪,上通于天。

  呜呼!双慈在堂,下有妹女,门祚衰薄,终鲜兄弟。淳一死不足惜,哀哀八口,何以为生?虽然,已矣!淳之身,父之所遗;淳之身,君之所用。为父为君,死亦何负于双慈?但慈君推干就湿,教礼习诗,十五年如一日;嫡母慈惠,千古所难。大恩未酬,令人痛绝。

  慈君托之义融女兄,生母托之昭南女弟。淳死之后,新妇遗腹得雄,便以为家门之幸;如其不然,万勿置后。会稽大望,至今而零极矣。节义文章,如我父子者几人哉!立一不肖后如西铭先生(3),为人所诟笑,何如不立之为愈耶?呜呼!大造茫茫,总归无后,有一日中兴再造,则庙食千秋,岂止麦饭豚蹄,不为馁鬼而已哉!若有妄言立后者,淳且与先文忠在冥冥诛殛顽嚚(4),决不肯舍!兵戈天地,淳死后,乱且未有定期。双慈善保玉体,无以淳为念。二十年后,淳且与先文忠为北塞之举矣。勿悲,勿悲。相托之言,慎勿相负。武功甥将来大器,家事尽以委之。寒食盂兰,一杯清酒,一盏寒灯,不至作若敖之鬼,则吾愿毕矣。新妇结褵二年,贤孝素著,武功甥好为我善待之。亦武功渭阳情也。

  语无伦次,将死言善。痛哉,痛哉!人生孰无死,贵得死所耳。父得为忠臣,子得为孝子,含笑归太虚,了我分内事。大道本无生,视身若敝屣。但为气所激,缘悟天人理。恶梦十七年,报仇在来世。神游天地间,可以无愧矣!

  注释:(1)此文为作者在清顺治四年(1647)被捕后于南京狱中写给生母陆氏与嫡母盛氏的绝笔书。(2)夏完淳父夏允彝,崇祯十年(1637)进士,南都失守,与陈子龙等起兵松江,兵败沉水死。(3)西铭先生:即张溥。张溥无子,死后钱谦益等为他立嗣子,名永锡。此子未能继承张溥的遗风,为人诟笑。(4)诛殛(jí极)顽嚚(yín银):诛杀顽钝之人。诛殛,诛杀。顽嚣,顽钝愚蠢之人。

1.对下列句子中加粗词语的解释,不正确的一项是( )

A、虐明朝 钟:集中

B、门衰薄 祚:福分

C、会稽大 望:盼望

D、昭南女弟 女弟:妹妹

2、以下六句话,分别编为四组,分别表现夏完淳的忠与孝的一组是( )

①一旅才兴,便成齑粉

②淳死后,乱且未有定期

③为父为君,死亦何负于双慈

④新妇结褵二年,贤孝素著

⑤大恩未酬,令人痛绝

⑥双慈善保玉体,无以淳为念

A、①④

B、③⑥

C、②⑤

D、②⑥

3、下列对原文有关内容的分析和概括,不正确的一项是( )

A、作者的嫡母,夏允彝死后,削发为尼;生母(夏允彝妾),夏允彝死后,寄居在异姓之家,作者对此深感内疚。

B、“门祚衰薄,终鲜兄弟”二句,语出晋李密《陈情表》,作者借此表达自己本应像李密一样在家尽孝,但国难当头,应当为国捐躯的爱国精神。

C、作者在信中表示,如果没有遗腹子,就千万不要另立后嗣。像西铭先生那样地让人立一个不肖的后嗣,为旁人所诟骂讥笑,还不如不立为好。

D、作者表示他与父亲在阴间也要诛杀清兵,绝不放过敌人,二十年后转世为人,再出师北伐,驱逐满清。
