【题目】Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.

Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.

The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful (有害的),it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem said Professor Peter Barnes.

Ten healthy volunteers (志愿者) were given the-obromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.

The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levels of capsaicin to cause a cough compared with the placebo.

The researchers said that theobromine worked by keeping down a nerve activity (神经活动),which caused coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.

【题目】A classical guitarist was excited to hear from New York City police that his valuable guitar had been found. It disappeared almost a year ago when he got out of a cab and forgot to take the guitar with him. Laurence Lennon, 44, said he was running late that day. He was talking to his manager on his cellphone when he dashed out of the taxi. He said that he gave the driver $ 60 and told him to keep the change. He walked through the front doors of the concert hall still talking on the phone to his manager.

Upon discovering his loss, Lennon used his cellphone to call the police. The policewoman asked him for the name of the cab company, the number of the cab, and the name of the driver. He said that she had to be kidding.

She told Lennon that he could file a missing items report at the police station or online. Lennon asked for the online address. She told him that finding the guitar might take a couple of years—finding guitars was not as important as finding murderers and marijuana smokers. Then she told him to have a nice day.

“This year has been depressing,” said Lennon. “I had to postpone the recording of two new CDs. I've been using borrowed guitars. And I was losing hope of ever recovering my guitar.”

Lennon was reunited with his $ 100,000 musical instrument yesterday. The case and the guitar had been discovered in the corner of a coffee house only two blocks from where Lennon had lost it in the first place. Lennon had offered a $ 10,000 reward for its return.
