A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.

  Researchers from the University of lows based their firdings on a review of 18 earlier studies that looked at the associstion between sunscreen use and melanoms(黑素瘤).They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.

  Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helpsprevent skin cancer, which is increasing in incidence(发生率)faster than any other cancer in the United States.

  But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.

  The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin concer-people with fair skin and freckles(雀斑),for example-are more likely to use sunscreen.As a result, it may appear that sunscreen users get cancer more often.

  The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

Wendy Gallegos writes “concer” on the board. One of her students raises her hand.
“Ms. Gallegos, you should have written ‘conocer’ instead,” she said, referring to the Spanish verb for “to know.”
Gallegos looks at the board, smiles and quickly erases her mistake.
“You see, I have taught you so well, you pick up on my mistakes,” she said with a laugh.
To Gallegos, the scene in her classroom is typical(特有的)of the children she teaches. Gallegos teaches high school Spanish. She became part of their lives and families for three years. She is willing to help her children succeed. After a couple of years, Gallegos’ class becomes like home. Gallegos’ Spanish class is taught mostly in English in sixth grade. By the time the students are eighth-graders, they are speaking fewer words of English and more of Spanish during the 50-minute classes.
“My goal is to get my kids to say something in Spanish every day,” she said, “I want them to be able to talk to me. That’s why I help them, I praise them, I recognize them when they do good work. And we have fun. The day I stop having fun is the day I am going to consider a different job.’’
If a student needs help, Gallegos offers the student a “lifesaver,” which is help from a classmate. The lifesaver gets a piece of candy as a reward. As the students said: “Gallegos’ class is anything but boring.” It is because of Gallegos’ efforts and determination that she is the teacher who they think is most deserving of one of Collier County’s Golden Apple Awards.
“I don’t teach a subject, I teach kids. This is what I was born to do,” Gallegos said.
