　Each child has his individual(个人的)pattern of social, as well as physical, development. Some of it depends on his home life and his relationships with the people who love him. Children in large families learn how to get along with others through normal brother- sister play and tussles (打斗). An only child, on the other hand , may have to learn his lessons in social living through hard experiences on the playground or in the classroom. Twins who always have one another to lean on may be slow in responding to others because they do not need anyone else.

　A child who is constantly scolded and made to feel he does everything wrong may have a difficult time developing socially. He may be so afraid of displeasing the adults around him that he keeps to himself (where he can’t get into trouble)or he may take the opposite route and go out of his way to create trouble. Like the deserted child, he too may return to infantile (幼稚的)pleasures, developing habits that will satisfy him, but create barriers(障碍)toward social contact.

　Robert Spring, a 19th century forger(造者), was so good at his profession that he was able to make his living for 15 years by selling false signatures of Americans. Spring was born in English in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he became rich by selling his small but real collection of early U.S. autographs (手稿). Discovering his ability at copying handwriting, he began imitating signatures of George Washington and Ben Franklin and writing them on the title pages of old bocks. To lessen the chance of detection(察觉), he sent his forgeries to England and Canada for sale.

　Forgers have a hard time selling their products. A forger can’t deal with a respectable buyer but people who don’t have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemicals.

　In Spring’s time. right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General“Stonewall ”Jackson. For several years Miss Fanny’s financial problems forced her to sell a great number of letters and manuscripts. Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp - eyed experts the difficult task of separating his forgeries from the originals.
