"Growing up， Einstein saw his father struggle to support the family and move the family for different jobs， Einstein had to move between schools and it was challenging for him to catch up with his new class．"

    This story about the struggles（奋斗）of famous scientists can't be found in your regular science textbook， but a new study suggested maybe it should be．

    In the study， 402 9th﹣ and 10th﹣grade students from four New York City high schools in low﹣income areas were divided into three groups． The students read some 800﹣word stories about Albert Einstein and Marie Curie． The control group read a regular science textbook description about their great achievements． Another group read about the scientists' personal struggles， like Einstein's running away from Nazi Germany． The third group read about the scientists' intellectual struggles， as they tried different experiments﹣﹣﹣ and failed．

    As it turned out，the students who had read about scientists' struggles， whether personal or intellectual， had higher grades than students who had read about achievements． Those who weren't getting good grades to begin with gained the most． Those in the control group not only didn't see a grade increase， they had lower grades than the grading before the study began．

    "We think that struggle stories showed scientists' weaknesses．" the researchers write， "which creates a sense of connection between the students and scientists． And that may make it easier for students to see them as role models．"

    "When kids think Einstein is a talent who is untouchable， then they believe they will never get there， "said lead researcher Xiaodong Lin﹣Siegler， PhD．

    If we want to educate a future generation of great scientists， we can start by changing the way we talk about the great scientists of the past． An 800﹣word story about scientists' failures， not just their achievements， in science textbooks will make it happen．

（1）What does the article mainly talk about？
