Yoga May Help Ease High Blood Pressure

People who follow the ancient practice of yoga may be getting an added health boost,with a new study suggesting it can fight high blood pressure一also known as hypertension.
"This study confirms many people's feelings that exercise may be useful in the control of hypertension,"said Dr. Howard."Yoga would be a useful adjunct in the lowering of blood pressure in certain populations."
_________(46)Although the study couldn't prove a cause-and-effect relationship,doing yoga two to three times a week was associated with an average drop in blood pressure readings from 133/ 80 to 130/77,the researchers said.
In comparison,the average decrease in blood pressure was smaller(134/83 to 132/82)among people who ate a special diet but did not do yoga.
In a bit of a surprise,doing yoga in tandem with a special diet did not outperform doing yoga alone.___________(47)
Dr. Howard said the study shows that"yoga can have a favorable effect" on hypertension. ________(48)"But some large population studies have suggested that changes of this magnitude could have very significant long-term benefits."
___________(49)including its relatively short length and the fact that most participants were young and had milder forms of high blood pressure,Dr. Howard said.
__________(50)"Yoga,along with deep breathing exercises,meditation and inner reflection,is a good adjunctive and integrative cardiovascular approach to better health,including lowering blood pressure,as this data suggests,"said Dr. David Friedman.
选项 __________(48)
A:The amount of change was small,he said.
B:Another expert agreed that the ancient Indian practice of yoga might ease hypertension.
C:In the study,researchers tracked 58 women and men,aged 38 to 62,for six months.
D:Yoga is proved to be effective in lowering high blood pressure.
E:The study did have some limitations.
F: This may be because doing both required a greater amount of time,making it more difficult for participants to stick with their regimens.

解析本题考查的是对所读材料的大意和主旨的掌握。前一句讲喻伽的功效，后一句讲这项研究的血压降低值。因此C选项放在这里最符合，指明了该项研究的时间、人群和年龄，与后文数值的出现连接得最合理。
本题考查的是对所读材料的大意和主旨的掌握。前一句提到了做瑜伽并且进行特殊饮食的人群并没有比只做瑜伽的人群血压降低得多。F选项最合适，说明了出现这种现象的可能原因。
本题考查的是对所读材料的大意和主旨的掌握。后一句说：但是，一些大型人群研究显示这一量级的变化会产生重大的长远效果。A选择最合适，并与后一句的“但是”“重大的长远效果”相呼应。
本题考查的是对所读材料的大意和主旨的掌握。后面说的都是研究的缺陷或局限性。E选择是唯一符合题意的。
