6.The high-protein,low-carbohydrate(碳水化合物) diets many people turn to for weight loss might have potentially harmful long-term effects on the colon,a small study indicates.In the study,UK researchers found that a protein-heavy,low-carb diet created certain changes in the colon that could contribute to colon cancer risk.The study itself does not show whether high-protein diets really raise the risk of any colon diseases,but the findings raise that possibility.
Diets relatively high in protein and lower in carbs have been shown to help heavy people lose weight."People should not be discouraged from losing weight,"Dr Flint said.However,he added,they should make sure that any weight loss plan includes adequate amounts of fiber and a high protein intake over months to years might have ill effects on the colon.
The findings are based on 17overweight men who followed three short-term diets:a one-week menu plan to keep their weight; a four-week high-protein diet with reasonable amounts of carbohydrates; and a four-week high-protein diet low in carbs.
On average,the study found when the men were on the high-protein diets,they had higher levels of substances known as N-nitroso compounds(亚硝基化合物) and other metabolites(代谢物) that have been linked to cancer.And when they were on the high-protein,low-carb diet,they had lowered amounts of fiber-originated compounds thought to be protective against cancer.
Exactly what those changes might mean for a person's health is not clear,But Flint said that the findings suggest that people should be cautious about consuming too much protein and too little fiber over a long period.In general,experts recommend that adults get about 28grams of fiber per day-though it's not known whether that's enough for someone on a high-protein weight-loss diet.

How does a doctor recognize the point in time when he is finally a"surgeon"?As my year as chief resident (进修医生) drew to a close,I asked myself this question on more than one occasion.
The answer,I concluded,was(50)D.When you can say to yourself,"There is no surgical patient I cannot treat competently (胜任地),treat just (51)B or better than any other surgeon"--then,and not until then,you are indeed a surgeon.I was (52)D that point.
Take,(53)A,the emergency situations that we met almost every night.The first few months of the year I had (54)C the ringing of the telephone.I knew it meant another critical resolution to be (55)A.Often,after I had told Walt or Larry what to do in a particular (56)D,I'd have trouble getting back to sleep.I'd (57)B all the facts of the case and,often,wonder if I had made a poor decision.More than once at two or three in the morning,after lying (58)A for an hour,I'd get out of bed,dress and drive to the hospital to see the patient myself.It was the only way I could find the (59)A of mind I needed to relax.
Now,in the last month of my residency,(60)C was no longer a problem.Sometimes I still couldn't be sure of my decision,but I had learned to accept this as a (61)B problem for a surgeon.I knew that with my knowledge and experience,any decision I'd made was certain to be a (62)C one.It was a nice feeling.
This all sounds conceited (自负的) and I guess it is--but a surgeon needs conceit.He needs it to encourage him in trying moments when he's bothered by the (63)D and uncertainties that are part of the practice of medicine.He has to feel that he's as good as and probably better than any other surgeon in the world.Call it conceit--call it self-confidence; whatever it was,I had it.And it is,I am sure,what a person has to make a(n) (64)B in life.

Too busy (51)D physical pain and obvious mobility limitation,I was not aware of this change at first.I was determined to (52)D,feeling good about the progress I had made,as I moved forward.
(53)C,as I made my first excursion outside the hospital,society had already assigned me a new status.Happy to be free of my restriction in the hospital,I rolled through the shopping mall-a (54)C survivor,feeling like a war hero.Unfortunately,I had a rude (55)A as I discovered that others did not view me in the way I had come to view myself.
All eyes were upon me,yet no one dared to make eye contact.Their efforts to(56)D my eyes forced me to realize they saw only my missing legs.Mothers (57)B held their children closer as I passed.Elderly women patted me on the head saying,"God Bless You!"with (58)A in their eyes.
While I sat thinking about what had happened,a small girl came up to me.She stared with unembarrassed (59)A at the empty pants.Finding nothing there,she looked up at me with a puzzled look,she innocently asked,"Lady,where did your legs go?"
I explained that my legs had been sick.Since my legs hadn't been strong and healthy like hers,the doctors had to (60)C them.Leaning her head upwards,she asked,"Did they go to‘Leg Heaven'?"
That incident made me think about how (61)A children and adults react to the unknown.To a child,an odd appearance is an interesting curiosity and a(62)B learning experience while adults often view the same thing with fear and horror.I began to realize that,I,too had been (63)B of the same inappropriate reactions before I knew what life was like for an amputee.
To fulfill the wholeness of my mind and spirit,I now smile warmly,make eye contact,and speak in a confident manner.By using a (64)C approach,I attempt to enlighten society about the fact that having a not-so-perfect body doesn't mean having a poor quality of life.

The next day,I convinced Justin it was time to set the moth free.He took it(42)D,opened the jar,and the little moth flew out.It(43)C the yard twice,came back,and landed on Justin's arm.He picked it up,tossed it in the air,and the moth repeated its (44)A pattern.He tried over and over,but each time it would (45)D to his arm.
