The scientists, le

Dr Sparrow and her team 3 four different memory experiments. In one, participants typed 40 bits o
18、f information into a computer. Half of the subjects insisted the information would be saved in the computer; the other half believed the contents they typed would be 4 . Those were more likely to remember information if they thought they would not be able to find it later. “Participants did not 5 to

The experiment explores an aspect of what is known as transactive memory (交换记忆) the 7 that we rely on our family, friends as well as co-workers to store information for us. “I love watching baseball,“ D

22、 potentially offering new 1 on how the brain recognizes speech, Japanese researchers say. It has already been 2 that monkeys, mice and other mammals can recognize different languages but this is the first time that birds have been found to 3 the ability, The Mainichi Daily News reported. A research
23、team 4 Java Sparrows to English and Chinese translations recorded by exchange students of two well-known Japanese novels, The Tale of Genji and Natsume Soseki“s I Am a Cat . A bird sitting on a perch first listened to the English 5 and was only allowed to eat afterwards. Then the researchers played
24、English and Chinese recordings at random and only allowed the bird to eat after hopping onto the perch with the English. The birds correctly identified the English recording 75 percent of the time. The same results were achieved with another two birds that were 6 to eat only when Chinese was played.
25、 “Humans are able to distinguish between languages, even ones they don“t know, from the intonation and pronunciation, and it seems that paddy birds have the 7 ability,“ said Keio University experimental psychology professor Shigeru Watanabe, who led the research. Watanabe said paddy birds like the J

When Ellen was a teenager, she loved to be out in the summer sun. She ran, she worked in h
28、er garden. She would swim and sit by the pool for hours soaking up the sunshine. And she never got tired of hearing people tell her how great her tan (古铜色) looked. B. As Ellen got older, she continued to spend lots of time outdoors in the sun. By the time she was in her forties, Ellen“s skin had dev
29、eloped a weathered look, with small 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 comp
30、letely cured. But Ellen had begun late in life to pay for all those years she had spent in the sun. Ellen isn“t unusual. The athletic, bronzed bodies we see in magazine ads and TV commercials constantly sell the idea that a good tan means health, attractiveness, and fun. The result is that many peop
31、le believe those ads. And they spend a lot of time in the sun often just trying to get tan. That golden or bronze color may look nice, but skin doctors know that sitting in the sun until you are baked several shades darker is not such a hot idea. C. According to the National Cancer Institute, over 4
32、00,000 Americans can expect to get some form of skin cancer this year. Most of these people will be 40 or older. However, skin cancer especially skin cancer caused by exposure to the sun can often take many years to develop. So it“s never too early to protect yourself in the sun. D. As soon as warm
33、weather arrives, lots of people who don“t already have dark skin want to start working on their tans. But a tan isn“t really nature“s way of making you look beautiful. A tan is your skin“s defense against the sun“s ultraviolet (紫外线的) radiation. UV rays damage skin cells. So when you decide to have a
34、 marathon roasting session in the sun, cells in your skin called melanocytes 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 that“s why you “tan“. E. Think of your tan as a
35、 shield of melanin your body produces to block out the UV radiation. The problem is, it“s a weak shield at best. There“s no way for your body to protect itself fully against the sun“s harmful rays especially if you expose yourself to the sun hour after hour, day after day, year after year. As you ge
36、t older, the buildup of many hours in the sun means more of a chance for skin damage and possibly skin cancer. F. 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 m
37、ore serious is the damage the sun“s UV rays can do to the DNA of skin cells. DNA is the genetic blueprint that cells use to reproduce. With damaged DNA, the skin may produce mutated (变异的) cells that start to grow in an uncontrolled way: skin cancer. G. Nature gives you a clue about how much sun is e
38、nough by the color of your skin. If your skin is light, you don“t 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 don“t be fooled into thin
39、king you can stay out in the sun indefinitely. You can“t. People with dark skin also get sunburned and can suffer skin damage. It just takes a bit longer for the damage to show up. H. The three most common types of skin cancer are all connected with exposure to the sun. The most common of these is b
40、asal cell carcinoma. Basal cancers often look like wax- like growths or red, scaly (有鳞的) patches. They appear most often on the face, neck, or hands. Squamous (有鳞片的) cell cancer is the second common type. This cancer spreads more quickly. Squamous cell cancers often appear on the head, hands, or oth
41、er sun-exposed parts of the body. They show up as sharply outlined red, scaly patches. The third type of skin cancer is called melanoma (黑素瘤). Melanoma is often caused by too much exposure to the sun, but it can be brought on by other things as well. Melanoma show up as brown or black mole-like (像痣的
42、) growths on the back and legs. They can also appear on the palms, fingers, and toes. Melanoma is the rarest of these three kinds of skin caner, 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. I. Si
43、nce all of these forms of cancer can 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 skin doctor, Dr. Louis Vogel. “Pay attention to anything on your skin
44、 that grows rapidly, that bleeds or has irregular color. Also, suspect any mole that itches or has some areas that are darker or higher than others.“ J. Although skin cancer is the most common form of cancer, it is also the most treatable if caught early. There are several methods of treatment. They
45、 include surgical removal, treatment with 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 you are out in the sun,“ warns Dr. Vogel. “When you are at t
46、he beach, wear sun blocks. There are many things in life you can“t prevent. But skin cancer is something you can often prevent if you take the proper precautions.“（分数：71.00）(1).Skin cancer may occur when the DNA of the skin cells is damaged.（分数：7.10）(2).Marks of growths on your skin should be paid a
