Pigeons may only have a brain the size of a thimble (顶针), but it appears that pigeons can categorize and name objects in the same way human children learn new words.

A new study from the University of Iowa has shown that the birds are capable of learning to categorize 128 different photographs into 16 basic categories.

Scientists taught three pigeons to sort out different kinds of dogs or types of shoes, for example by using a particular symbol in exchange for a reward. When they were shown black and white pictures of previously unseen dogs or shoes, the birds were able to correctly match these with the corresponding symbols.

The scientists behind the project say this is a similar approach taken by young children when they are first learning words for objects. However, the researchers said it look their birds around 40 days to perfect the task of learning just 16 categories.

Professor Edward Wasserman, who led the work, said: “Our birds’ rate of learning appears to have been quite slow. Would children learn faster than pigeons? Almost certainly. However, our pigeons came to the experiment with no background knowledge at all. Thus, the more relevant comparison group may be newborn babies, who indeed take 6-9 months to learn their first words.”

Writing in the journal Cognition, the researchers said their experiment was a very simple mirror of the way children are taught words — by their parents pointing to pictures and asking them to name the object.

Pigeons are known to be smarter than many birds. Professor Bob McMurray, who also took part in the study, said the results showed that human learning is not as unique as was previously believed.

He said: “Children are facing a huge task of learning thousands of words without a lot of background knowledge to go on. For a long time, people thought that such learning is special to humans. What this research shows is that the ways in which children solve this huge problem may be shared with many species.

B. Pigeons are known to be smarter than newborn babies.

How to Deal With Gossip (流言蜚语)

Gossip is a double-edged sword. Not only can it be incredibly harmful for you, but also others may be affected. Do a serious favor for your friends and yourself --- quit your gossip habit and become a better and more positive person. It’s good to find ways to get started dealing with gossip.

●Face the source of the rumor directly. If you know for sure who’s responsible for spreading a rumor about you, don’t take it lying down. When you have a chance, walk right up to him or her and say that you don’t appreciate the mean things she/he has said. Stay calm when you do this. You don’t want to adopt the cruel words this person has.1.

●Alert your friends. If you learn that someone’s been spreading nasty rumors about you, your first action should be to consult with your close friends. 2. Tell them the facts of the situation. If the rumor’s not true, they’ll be sure to fight the spread of the rumor. If the rumor is true, they can still help stop its spread by sticking up for you.

●Ignore it. 3. When you hear gossip about yourself, laugh it off. Act as if it’s ridiculous! Share a chuckle(窃笑) about it! Turn the tables by making the person who started the rumor the butt (笑柄) of the joke.

●4. If nasty rumors and gossip are a frequent problem, or if someone’s told a rumor that might get you in trouble for something you didn’t do, talk to a teacher, counselor, or administrator. These people can help you work through the problem. They can give you advice on how to proceed, make you feel better, and even discipline people who’ve started the rumor.

●Stay away from people who gossip. The single best way to avoid having gossip told about you is to stay away from the kinds of people who tell mean gossip! As popular or cool as they may seem, these people are sad and desperate. They can’t have a good time without spreading hurtful rumors about someone else. Don’t bother with them. 5. Remember a friend who stabs you in the back by telling a nasty rumor isn’t much of a friend at all.

A. When you’re worried about a piece of gossip, change the way you live.

B. Tell an authority about it.

C. Gossip is often best dealt with by paying no attention to it at all.

D. They should be people you know and trust.

E. Work out a plan to avoid being laughed at.

F. Find friends who don’t get enjoyment from hurting people.

G. You also don’t expect to give bystanders the impression that the rumor’s true.

CHICAGO (Reuters) - Smoking not only can wrinkle(起皱纹) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.

The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.

"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.

"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.

The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers Independent judges decided how wrinkled each person's skin was.

When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.

Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.

The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（紧缩）, reducing blood supply to the skin.

Smoking can also damage the connective tissue that supports both the skin and the internal organs.

66. The best title for this passage would be_______.

A. The danger of smoking        B. A survey of smokers

C. Quit smoking for health       D. Smoking causes skin aging

67.  how wrinkled each person's skin doesn’t relate to_______.

A. the number of cigarettes a person smokes

B. the kind and characteristics of skin

C. how long a person smokes

D. how long skin is under sunlight

68. It can be inferred from the study _______.

A. smoking won’t make skin protected from the sun age

B. smoking will do damage to skin rather than other organs

C. smokers over 65 usually won’t worry about their skin

D. the age of smokers is not connected with the result of the test

69. From the passage smoking results in skin aging mainly because_____.

A. it will lower blood supply to skin.

B. it can make you feel tired

C. it can make skin come off

D. it can make blood run faster

70. The main purpose of the passage is to ______.

A. inform people about the result of the study

B. advise people to how to protect skin

C. warn people not to smoke again.

D. introduce a new way of avoid skin aging
