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, 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 were given theobromine, 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 is stopping coughs.

The team found that, when the volunteers were given theobromine, the capsaicin needed 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 causes coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.

1.According to Professor Barnes, theobromine ______.

A. cannot be as effective as codeine

B. can be harmful to people’s health

C. cannot be separated from chocolate

D. can be a more effective cure for coughs

2.We learn from the text that volunteers in the experiment _______.

A. were patients with bad coughs

B. were divided into three groups

C. received standard treatments

D. suffered little side effects

3.Which of the following would be the best title for the text?

A. Codeine: A New Medicine

B. Chocolate May Cure Coughs

C. Cough Treatment: A Hard Case

D. Theobromine Can Cause Coughs

Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn’t only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.

The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren’t jealous of him.

In short, we don’t laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person’s emotions, he will certainly like it a lot.

1. What did the author find out after studying psychology?

A. Only good jokes make people laugh

B. Many factors lead to people laughing.

C. Funny things can make people laugh

D. Laughter can make people healthy.

2.Why did the audience laugh loud at the pedestrians?

A. They played a trick on the pedestrians.

B. The pedestrians behaved in a funny way.

C. They could feel the pedestrians’ happiness.

D. Their emotion was approved of by the show.

3.What does the underlined word “belittling” probably mean?

A. Annoy B. Blame C. Look down on D. Make up to

4. What is the author’s attitude towards those who take pleasure in making fun of others?

A defensive B indifferent C negative D casual
