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

Barton was born into a freethinking family in 1821. Her elder brothers and sisters happily educated her in math and reading, so when she entered school at three years old, she could read and spell three-syllable words. 【小题1】

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. 【小题2】 Barton lost her appetite（食欲）and cried constantly. After only one term, she had to be brought home. Then, Barton stayed out of school to nurse her 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 give away food , bandages, medicines, and other supplies to the Union Army.

 【小题3】 There, with little concern for her own safety, she cooked meals, assisted surgeons, and comforted wounded soldiers.

Eventually, because of working too hard , Barton broke down finally. 【小题4】 It was there that she learned of an organization based in Switzerland called the International Committee of the Red Cross , whose work mirrored her own.

Shortly after Barton arrived back home in 1873,her sister died. 【小题5】 When recuperating（康复）at a health facility in New York, she began planning for the establishment of an American wing of the International Committee of the Red Cross. Although at first the government opposed it, 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.

In 1882，at 19 months old，Helen Keller unfortunately 【小题1】（catch）a fierce fever. She survived but the fever left its mark--she could no longer see 【小题2】 hear. It was as if she had been thrown into a dark prison cell. 【小题3】（luck），Helen was not someone who gave up easily. She began to explore the world 【小题4】 using the other senses. By the age of seven，she had invented over 60 different signs by means of 【小题5】 she could talk to her family.

With days passing by，Helen came 【小题6】（realize）that she was different from others and that there were a lot of 【小题7】（restrict）on her communication. This made her so angry that her behaviour was often【小题8】（bear）. Eventually，it became clear that something had to be done.

Besides，she even learnt to speak，a major 【小题10】（achieve）for someone who could not speak at all.

Helen made continual efforts to go deeper into the kingdom of knowledge，and her perseverance（坚持不懈）paid off at last.
