The early lack of exposure to science ，technology，engineering and mathematics (STEM) can be harmful to achieving gender (性别）balance in these fields. It begins when we are young and continues throughout our time in high school.

While at home，girls generally don’t get to experience the level of exposure or encouragement in STEM fields that their male counterparts do. It is often subtle ，but it’s the first hurdle that faces and confuses so many women. Boys ，on the other hand, get on their path ，and are encouraged to do so， generally earlier than girls. For example ，boys are more often given science sets as toys ，which spark an interest in these subjects.

In school ₃ boys are often pushed to take the more challenging math and science classes. So if we want to attract the best and brightest minds into the fields that will advance us as a people _? a country，and a planet，we can no longer look to only half of the population. Young girls cannot possibly consider opportunities they do not know exist. If girls are not exposed to certain subject and career paths，they are highly unlikely to choose to follow them in college.

Our bias(偏见)toward girls₉ either from families or from schools ，is so rooted in our culture that we often don’t even recognize it. Although the situation Has changed greatly in the past 20 or 30 years，there is still a sense that girls aren't as good at math ₉ for instance ₉ even though there is almost no evidence to support such a belief.

It is important that as a society we deal with gender stereotypes long before young people are faced with a decision to declare or choose a major in college. Without making efforts to break them， we are limiting the potentials of our youth，both male and female. Providing the necessary resources， exposure _, and encouragement would help young women understand that their gender shouldn^’t determine the career path they choose, and that pursuing a STEM career does not make them less feminine.

     Since 1984, Philadelphia has been cleaning up its act. One by one, graffiti-covered walls are being changed

into outdoor art. So far, more than 1,800 murals (壁画) have been painted. Philadelphia now has more murals

than any other American city.

     The walls that were once ugly with graffiti (涂鸦) are now covered with beautiful pictures of historical

heroes and modern art, thanks to the Mural Arts Program (MAP). Its work makes schools and public places

attractive, and its citizens very proud. The program began as part of Philadelphia's Anti-Graffiti Network. Jane

Golden is the MAP's artistic director. "When people ask me what our program is about," she says, "I answer

them with one word: hope." Each year, the MAP offers youth art programs and workshops. Some one-time

graffiti writers even help paint MAP murals.

     The MAP's work, says Golden, is all about developing a sense of community (社区). When a neighborhood

requests a mural, the MAP works with the people there to develop a message. Some messages have been "Safe

Streets," "Love and Care," and "Peace Walk."

     The MAP receives up to 50 requests for murals each week. Last year, the workers painted 140 murals.

     "The making of a mural enters people's collective memory as an extraordinary, pleasant moment in

neighborhood history" says Golden, who began as a muralist in Los Angeles.
