　　He was struggling(费劲)to tie his shoes．I was struggling with whether I should help him．

　　I did, and he was grateful．

　　“Thank you,”he said．

　　“I'm glad I could help．I just thought it would be easier for me to reach,”I said．

　　He was a disabled man, and forced to look down most of the time．His arms and legs were twisted(扭曲的)terribly, and he couldn't do what the rest of us would consider easy tasks．He always managed to look up to see how you reacted(反应)to his words, however．He had a big smile, making me feel comfortable．

　　I was still on my knees by his wheelchair．

　　“Nice shoes,”he said．

　　“Thanks．No one ever complimented me on them before,”I said．

　　“No one has the same view of the world as I do,”he replied．

　　“Tell me about the world as you see it,”I said smiling．

　　“Most people can see if someone is comfortable with them or not in their eyes．I see it in their feet．”he said．“If people keep moving their feet, I just let them go, because I know they're impatient with me．I don't want to make people uncomfortable．

　　“What about me?I asked．

　　“I could see your compassion．And then you came down to my level．I was the one who was nervous．”he said．“I don't normally have someone look me in the eye．”

　　“They don't know what they're missing,”I told him．

　　“My old face is nothing to brag(自夸)about．”he said．

　　“But that smile is so big．”

　　Yes, and it's not only a big smile but an attitude．

　　Not all memories are sweet．Some people spend all their lives trying to forget bad experiences．Wars and traffic accidents can leave people with terrible physical and emotional(精神上的)scars．Often they appear again in dreams．

　　Now American researchers think they are close to developing a pill, which will help people forget bad memories．The pill is designed to be taken immediately after a frightening experience．They hope it might reduce, or possibly erase(抹去)the effect of sad memories．

　　In November, some scientists tested a drug(药)on people in the US and France．The drug stops the body producing chemicals(化学品)that fix memories in the brain．So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased．

　　The research has caused plenty of argument．Some think it is a bad idea, while others support it．

　　Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war．They say that there are many people who suffer from terrible memories．

　　“Some memories can destroy people’s lives．They come back to you when you don’t want to have them in a dream．They usually come with very sad emotions．” said Roger Pitman, a scientist of psychiatry at Harvard Medical School．“This could relieve(减轻)a lot of that suffering．”

　　But those who are against the research say that it is very dangerous to change memories because memories give us our identity(特质)．They also help us all get away from the mistakes of the past．

　　“All of us can think of bad events in our lives that were terrible at the time but make us who we are．I’m not sure we want to erase those memories,” said Rebecca Dresser．

　　Dogs are known for their sense of smell．They can find missing people and things like bombs and illegal drugs．Now a study suggests that the animal known as man's best friend can even find bladder(膀胱)cancer．

　　Cancer cells(细胞)are thought to produce chemicals with unusual smells．Researchers think dogs have the ability to smell these smells, even in very small amounts, in urine(尿)．The sense of smell in dogs is thousands of times better than in humans．

　　The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner．The man was later found to be skin cancer．

　　Carolyn Willis led a team of researchers at Amersham Hospital in England．They trained different kinds of dogs for the experiment．The study involved urine collected from bladder cancer patients, from people with other diseases and from healthy people．

　　Each dog was tested 8 times．In each test there were 7 samples for the dogs to smell．The dog should signal the one from a bladder cancer patient by lying down next to it．Two cocker dogs were correct 56 percent of the time．But the scientists reported an average success rate of 41 percent．

　　The British Medical Journal published the research．In all, 36 bladder cancer patients and 108 other people took part．During training, all the dogs reportedly even identified(认出)a cancer in a person who had tested healthy before the study．Doctors found a growth on the person's right kidney(肾)．

　　Carolyn Willis says dogs could help scientists identify the combined(合成)chemicals produced by bladder cancer．That information could then be used to develop machines to test for the chemicals．The team also plans to use dogs to help identify markers for other kinds of cancer．
