Relaxation therapy ( = treatment). If you read the sentence out loud, your blood pressure will go up. If you talk to another person, it will go still higher. If the talk is with your boss, your pressure will go even higher. If you speak to someone of the opposite sex, your pressure may show less change if you ’ re married than if you ’ re single. Dozens of times each day, your blood pressure changes with what you ’ re feeling and doing. These “ ups and downs” take place in everyone, but they are more severe in people with high blood pressure. That discovery is the basis for the newest therapy: controlling blood pressure by learning skills to control everyday stress. Many patients control their blood pressure with the relaxation response. This takes four simple things: a quiet environment, a comfortable position (sitting or lying down), the repeating of a word, prayer or phrase each time you breathe and having none of other thoughts. Something remarkable happens when you do this, according to research in Boston. Relaxation of the mind and body has the effect that some blood-p ressure pills would have. What ’ s more, the blood pressure stays lower, just as it would with a pill, after you have stopped the relaxation and have returned to the stress of daily life.  31. The first paragraph tells us the reason why your blood pressure goes up is that__________.  A. you read aloud a sentence B. the man you talk to is your boss C. you ’ re not married D. you ’ re nervous 32.

A. needs a new kind of medicine B. has the same effect as blood-pressure pills C. is more than blood-pressure pills D. is working and can be improved
