孙思邈不仅认真学习，而且在碰到疑难病无法治疗时，也从不畏缩，而是勤于思考，深入研究，尽力找出治疗的办法。有一次，一个病人得了尿闭症（尿潴留）不能小便，急忙找来孙思邈治疗。孙思邈看他的小肚子涨得那么厉害，心想，吃药怕来不及了，便想找一根管子插进 * * 试验。想到葱管又空而且又软又细，不妨用它来试试，便要了一根细葱，在葱叶的一头切去少许，细心地慢慢地插进了病人的 * * ，再用劲一吹，不一会儿，尿果然沿着葱管流了出来，病人胀大的小肚子慢慢地瘪了下去，病人尿闭症的痛苦顿时消失。孙思邈是最早使用导尿术治疗尿潴留的人。这体现了孙思邈哪方面的医德品格（）。

Want to lose weight? Try eating. That’s one of the ways being developed by scientists experimenting with foods that trick the body into feeling full.

At he Institute of Food Research in Norwich, England, food expert Peter Wilde and his colleagues are developing foods that slow down the digestive system, which then sends a signal to the brain that stops appetite. “That fools you into thinking you’ve eaten far too much when you really haven’t,” said Wilde. From his studies on fat digestion, he said it should be possible to make foods, from bread to yoghurt, that make it easier to diet. While the research is still in its early stages, Wilde’s approach to controlling appetite is one that some doctors say could be a key to solving the problem of obesity.

“Being able to switch off appetite would be a big help for people having trouble losing weight,” said Steve Bloom, a professor of investigative medicine at London’s Imperial College, who is not connected to Wilde’s research. Bloom said that regulating appetite through foods is theoretically possible. But Bloom warned that controlling appetite may be very challenging. “The body has lots of things to prevent its regulatory systems from being tricked,” he said.

Wilde’s research makes use of the body’s ways of digesting fat. Fat normally gets broken down in the first part of the small intestines (肠道). When you eat a high-fat meal, however, the body can only digest the fat entirely further down in the intestines, which then causes the body to produce a kind of chemical to stop the appetite.

Wilde’s approach copies what happens with a high-fat meal. He coats fat droplets (滴) in foods with modified proteins from plants, so it takes longer for the chemical that breaks down fat to reach it. That means that the fat isn’t digested until it hits the far reaches of the intestines. At that point, intestinal cells send a signal telling the brain it’s full. Even though the body hasn’t had a high-fat meal, it stops the appetite as if it has. If the fat had been digested earlier in the intestines, no such signal would be sent.

51. According to Wilde’s research, what could people do if they want to lose weight?

B. It is sure to switch off the appetite of people with a weight problem.

C. It sounds terrible because regulating appetite through foods is not practical at all.

D. It’s no that easy to trick the body so more research should be done.

A. A kind of chemical is added to make a high-fat meal less fatty.

B. Fat is digested earlier and the body sends a signal telling the brain it’s full.
