She ran, she worked in her garden. She would swim and sit

4、 by the pool for hours soaking up the sunshine. And she never got tired of hearing people tell her how great her tan looked.As Ellen got older, she continued to spend lots of time outdoors in the sun. By the time she was in her forties, Ellens skin had developed a weathered look, with small creases(

5、褶皱) and wrinkles. That was okay, but she also began to notice brown patches developing on her face and hands. Ellen saw a doctor and found out she had a relatively mild case of skin cancer. Ellen was lucky. Her cancer was detected early. With early treatment, she was completely cured. But Ellen bega

6、nlate in life to pay for all those years she had spent in the sun. Ellen isnt unusual. The athletic, bronzed bodies we see in magazine ads and TV commercials constantly tell the idea that a good tan means health, attractiveness, and fun. The result is that many people believe those ads. And they spe

7、nd a lot of time in the sunoften just trying to get tan. That golden or bronze color may look nice, hot skin doctors know that sitting in the sun until you are baked several shades darker is not such a hot idea.According to the National Cancer Institute, over 400,000 Americans can expect to get some

8、 form of skin cancer this year. Most of these people will be 40 or older. However, skin cancerespecially skin cancer caused by exposure to the suncan often take many years to develop. So its never too early to protect yourself in the sun.Whats a tan?As soon as warm weather arrives, lots of people wh

9、o dont already have dark skin want to start working on their tans. But a tan isnt really natures way of making you look gorgeous. A tan is your skins defense against the suns ultraviolet(UV) radiation. UV rays damage skin cells. So when you decide to have a marathon roasting session in the sun, cell

10、s in your skin called melanocytes(黑色细胞) go to work overtime. They produce an extra supply of melanin(黑色素), the brown/black pigment(色素) that gives your skin its color. That extra melanin makes your skin darker, and thats why you “tan“.Think of your tan as a shield of melanin your body produces to blo

11、ck out the UV radiation. The problem is, it is a weak shield at best. Theres no way for your body to protect itself fully against the suns harmful raysespecially if you expose yourself to the sun hour after hour, clay after day, year after year. As you get older, the buildup of many hours in the sun

12、 means more of a chance for skin damage and possibly skin cancer.This skin damage takes two general forms. Some UV attacks supporting cells in the lower layer of the skin, called the dermis(真皮). That causes skin to get dry, tough, and wrinkled. Even more serious is the damage the suns UV rays can do

13、 to the DNA of skin cells. DNA is the genetic blueprint that cells use to reproduce. With Damaged DNA, the skin may produce mutated(使变异，突变)cells that start to grow in an uncontrolled way: skin cancer.Nature gives you a clue about how much sun is enough by the color of your skin. If your skin is ligh

14、t, you dont have much built-in protection against the sun. You probably tan very little, if at all. So be very careful in the sun.If you have dark skin and dark hair, you can probably stand a bit more sun exposure. Just dont be fooled into thinking you can stay out in the sun indefinitely. You cant.

15、 People with dark skin also get sunburned and can suffer skin damage. It just takes a bit longer for the damage to show up.Types of skin cancerThe three most common types of skin cancer are all connected with exposure to the sun. The most common of these is basal cell carcinoma. Basal cancers often

16、look like waxy, pearly growths or red, scaly patches. They appear most often on the face, neck, or hands.Squamous cell cancer is the second most common type. This cancer spreads more quickly.Squamous cell cancers often appear on the head, hands, or other sun-expend parts of the body. They show up as

17、 sharply outlined rod, scaly patches.The third type of skin cancer is called melanoma. Melanoma is often caused by too much exposure to the sun, but it can be brought on by other things as well. Melanomas show up as brown or black mole-like growths on the back, legs, or torso(人体的躯干). They can also a

18、ppear on the palms, soles of the feet, fingers, toes.Melanoma is the rarest of these three kinds of skin cancer, but it is the most serious form. While the overwhelming majority of basal and squamous cell cancer cases can be cured, many melanoma cases are fatal.Since all of these forms of cancer can

19、 resemble harmless skin marks of irritations, be aware of marks of growths on your skin. And consult a doctor if you notice any changes.“In general, look for anything new in your skin,“ advises dermatologist, Dr. Louis Vogel.“Pay attention to anything on your skin that grows rapidly, that bleeds or

20、has irregular color. Also, suspect any mole that itches or has some areas that are darker or higher than others.“Although skin cancer is the most common form of cancer, it is also the most treatableif caught early.There are several methods of treatment. They include surgical removal, treatment with

21、heat, extreme cold and freezing, as well as chemical treatment and use of X-rays. However, as with many other diseases, the most important “cure“ is prevention. “Cover as much skin as possible when youre out in the sun,“ warns Dr. Vogel. “When youre at the beach, wear sun blocks. There are many thin

22、gs in life you cant prevent. But skin cancer is something you can often prevent if you take the proper precautions.“2 Ellen was pleased to hear people praise her great tan skin.（A）Y（B） N（C） NG3 Many people believe in the ads in magazines and TV commercials that a good tan means health, attractivenes
