    Clara Barton,founder of the American Red Cross,gained worldwide honor for her dedication to easing human suffering and earned the nickname  “Angel of the Battlefield.”

    Barton was born into a liberal (开明的) freethinking family in 1821. Her elder brothers and sisters happily tutored her in math and reading, so when she entered school at three years old, she could read and spell three-syllable words.

    Concerned about Barton's difficulty in making friends, her parents sent her to a boarding school, hoping it would make her more comfortable with her peers. Barton lost her appetite and cried constantly. After only one term, she had to be brought home. Then, Barton stayed out of school to nurse her older brother through a serious injury and also volunteered to care for poor families during a smallpox (天花)outbreak.

    In 1861,the Civil War broke out. The sight of wounded soldiers touched Barton deeply. She began to collect and distribute food, bandages, medicines, and other supplies for the Union army.

    There, with little concern for her own safety, she cooked meals, assisted surgeons, and comforted wounded soldiers.

    Eventually,because of working too hard,Barton collapsed,ill with typhoid fever (伤寒症). It was there that she learned of an organization based in Switzerland — called the International Red Cross, whose work mirrored her own.

    Shortly after Barton arrived back home in 1873,her sister died. When recuperating (休养)at a health facility in New York,she began planning for the establishment of an American wing of the International Red Cross. Although at first the government resisted,her efforts finally paid off. The American Red Cross was officially organized on May 21, 1881. Her influence lives on today in the work of the organization she founded.

A. Barton fell into a deep depression.

B. Unfortunately, it had the opposite effect.

C. Many people felt sorry for the loss of her sister and her own health.

D. Barton risked her life to transport wagonloads of supplies to the front lines.

E. When she recovered, her doctors prescribed (指示) a long, restful trip to Europe.

F. Barton spent the following several months learning basics about Swiss Cross.

G. She easily kept up with the older children academically but did not fit in socially.

阅读下面短文,从短文后各题所给的四个选项(A、B、C和D)中,选出可填入空白处的最佳选项。

    The town I live in is about to put cameras at all traffic lights to catch people who run red lights. It 1 me of how many people I've seen who take the yellow light as a signal to go faster. I also can't 2 why people don't move when the traffic light has turned green. Above all, there are those 3 situations in which someone doesn't even 4 that the light is red, and just keeps going. That is why so many accidents happen! All these situations make me 5 about the purpose of traffic lights.

    However, it's even more 6 to imagine letting people make their own 7 at crowded crossroads. Do the biggest cars get to go first? Who decides who goes next? 8 I guess I do like the idea of a system to 9 traffic. And I'll do my best to 10 the traffic rules: to go, to be 11, and to stop when I'm supposed to.

    It occurs to me that my 12 have done much the same for me in 13 of teaching me how to live. They have given me many 14 lights: to get along well with others, to listen and talk to them, to help others, and to live with 15 and purpose. They have also given me some red lights so that my 16 doesn't go astray (误入歧途): not to be greedy, to keep my temper, and to control my desires. And there also have been some yellow caution lights: to watch how much I drink, to keep control of my behavior, and to 17school regularly and work hard.

    If I obey these rules, my life will be as 18 as it can be. Just as I'm wise to pay attention to the traffic lights when I'm walking 19 the street, I'm wise to pay attention to the "life 20" given to me by my parents.

    项羽引兵西屠咸阳,杀秦降王子婴,烧秦宫室,火三月不灭;收其货宝妇女而东。人或项王曰:“关中阻山河四塞,地肥饶,可都以霸。”项王见秦宫室皆以烧残破,又心怀思欲东归,曰:“富贵不归故乡,如衣绣夜行,谁知之者!”说者曰:“人言楚人沐猴而冠耳,果然。”项王闻之,烹说者。

项王使人致命怀王,怀王曰:“如约。”乃尊怀王为义帝。项王欲自王,先诸将相。谓曰:“天下初发难时,假立诸侯后以伐秦。然身被坚执锐首事,暴露于野三年,灭秦定天下者,皆将相诸君与籍之力也。义帝虽无功,故当分其地而王之。”诸将皆曰:“善。”乃分天下,立诸将为侯王。立沛公为汉王,王巴、蜀、汉中,都南郑。项王自立为西楚霸王,王九郡,都彭城。

春,汉王部五诸侯兵,五十六万人,东伐楚。项王闻之,即令诸将击齐,而自以精兵三万人南从鲁出胡陵。四月,汉皆已入彭城,收其货宝美人,日置酒高会。项王乃西从萧 , 晨击汉军而东,至彭城。日中,大破汉军。汉军皆走,相随入榖、泗水,杀汉卒十余万人。汉卒皆南走山,楚又追击至灵壁东睢水上。汉军却,为楚所挤,多杀,汉卒十余万人皆入睢水,睢水为之不流,楚围汉王三匝。于是大风从西北而起,折木发屋,扬沙石,窈冥昼晦,逢迎楚军。楚军大乱,坏散,而汉王得与数十骑遁去,欲过沛,收家室而西;楚亦使人追之沛,取汉王家,家室皆亡,不与汉王相见。汉王道逢孝惠、鲁元 , 乃载行。楚骑追汉王,汉王急,推堕孝惠、鲁元车下 , 滕公常下收载之。如是者三。曰:“虽急不可以驱,奈何弃之?”于是遂得脱。

(选自《史记·项羽本纪》,有删节)

注①萧:萧县。②榖:榖水。③孝惠、鲁元:指孝惠帝、鲁元公主。

    A . “关中”指函谷关以西,今陕西渭河流域一带,这里山河险要,土地肥沃。古代的“关”专指函谷关。 B . “致命”指传达言辞、使命。文中“使人致命怀王”的意思是派人去怀王那里传达项王的有关指示。 C . “诸侯”诸侯是古代中央政权所分封的各国国君的统称。周代诸侯分为公、侯、伯、子、男五个等级。 D . “家室”指家眷的金银财宝。“收家室而西”的意思是接取到家眷从西边带来的金银财宝。
  3. (3) 下列对原文有关内容的概括和分析,不正确的一项是(   )
    A . 项羽手段残忍。为夺天下,他向西进军,屠戮咸阳,杀死降王子婴,焚烧秦宫,大火三月不熄。 B . 项羽怀有私心,他为实现称王的目的,攻下咸阳后,就派人向怀王禀报战况,封诸将为侯王,封沛公为汉王,封自己为西楚霸王。 C . 项羽善于用兵,在彭城之战中,项羽的军队把汉王的军队打得四处逃散,杀死汉兵十多万人,把汉军追赶到灵壁东面的睢水边上。 D . 项羽做事迟疑,在睢水之战中,项羽的军队把全体汉军层层包围,但没有抓住有利战机,致使汉王借飓风从西北吹来之际得以逃脱。
