"I would almost rather see you dead," Robert S. Cassatt, a leading banker(银行家)of Philadelphia, shouted when his twenty-year-old eldest daughter announced that she wanted to become an artist. In the 19th century,playing at drawing or painting on dishes was all right for a young lady, but serious work in art was not. And when the young lady's family ranked among(跻身于)the best of Philadelphia's social(社交界的)families, such an idea could not even be considered.

That was how Mary Cassatt, born 1844, began her struggle as an artist. She did not tremble before her father's anger. Instead, she opposed(抗拒)him with courage and at last made him change his mind. Mary Cassatt gave up her social position(社会地位)and all thought of a husband and a family, which in those times was unthinkable for a young lady. In the end, after long years of hard work and perseverance(坚持), she became America's most important woman artist and the internationally recognized leading woman painter of the time.

Annealing

Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly, for example by dipping (浸)it in water, it will be very hard but also very brittle(脆)-that is, It will break easily. Metal that has been annealed is soft but does not break as easily. It is possible to make metal as hard or as soft as is wished,　　 by annealing it. The metal is heated, and allowed to cool slowly, for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other materials, such as glass.
