Thomas Alva Edison was awarded more patents on inventions than any other American.When he died in 1931,Americans wondered how they could best show their respect for him.One suggestion was that the nation observe a minute or two of total blackout.All electric power would be shut off in homes,streets,and factories.Perhaps this suggested plan made Americans realize fully what Edison and his inventions mean to them.Electric power was too important to the country.Shutting it off for even a short time would have led to complete confusion.A blackout was out of the question.

A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that researched how pre-recorded videos of hypertension (高血压) patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months.

   Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies(疗法) have been relatively ineffective because people find it hard to follow those medical requirements.

   In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure.

  While the study did not address how the story-telling influenced the patients' behavior, Houston doubts that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.

We can learn from the text that the pre-recorded videos _________.

   A. tell medical histories of hypertension patients

   B. introduce some medical treatments of hypertension

   C. introduce a good lifestyle for hypertensive patients

   D. tell scientific discoveries of the scientist group

Houston was surprised to find that _______.

   A. hypertension is really difficult to control      

B. communication has some medical effects

   C. medical treatments have no effect at all    

D. people don't follow the medical requirements

The underlined word "address" in the last paragraph most probably means _______.

   A. persuade   B. observe     C. attend    D. announce

Which of the following could be the best title of the text?

   A. The stories of some hypertension patients. 

 B. Medical treatments of blood pressure.

   C. Storytelling may help lower blood pressure.

  D. Suggestions about how to lower blood pressure.
