Passage Two

Questions 62 to 66 are based on the following passage.

Yoga induces a feeling of well-being in healthy people, and can reverse the clinical and biochemical changes associated with metabolic syndrome, according to results of studies from Sweden and India. Metabolic syndrome is a cluster of heart disease risk factors such as high blood pressure, obesity and high blood sugar.

Dr. R.P. Agrawal, of the SP Medical College, Bikaner, India, and colleagues evaluated the beneficial effects of yoga and meditation in 101 adults with features of metabolic syndrome. In the study, 55 adults received three months of regular yoga including standard postures and Raja Yoga,while the remaining received standard care.

Waist circumference, blood pressure, blood sugar, and triglyceri HDL cholesterol levels were higher in the yoga group as compared joumal Diabetes REsearch and Clinicat Practice.

In the second study, published online December 19 in BioMed Central Complementary and Alternative Medicine, Dr. Anette Kjellgren from the University of Karlstad, Sweden and colleagues evaluated the beneficial effects of yoga-like breathing exercises on healthy volunteers.

55 adults were advised to practice "Sudarshan Kriya," which involves cycles of slow, normal and rapid breathing exercises. The exercises were practiced for an hour daily, six days a week for six weeks, while 48 controls were advised to relax in an armchair for I 5 minutes daily.

At the end of the study period, feelings of anxiety, stress and depression were significantly lower and levels of optimism significantly higher in the yoga group compared to the control group, Kjellgren and colleagues report.

Yoga not only helps in prevention of lifestyle. diseases, but can also be "a powerful adjunct therapy when these diseases anse,” co-investigator Dr. Faahri Saatiglou, from the University of Oslo, told Reuters Health. "We do not emphasize this point enough in our Westem health care."

听力原文： Have you always wanted to invest, but didn't know where to get started? Here are three basic guidelines to smart investing, for your future.

Number one is to have clear goals. Decide how many years you will invest for, and what your needs will be in the future.

Number two is to understand the range of possibilities. You'll want a diversified portfolio: one with a mix of stocks, mutual funds, bonds, and cash. It's a jungle out there. Each of these products has different risks associated with them and also different potential rewards. Understand them before you buy, so there won't be any big surprises later.

Finally, number three is to have realistic expectations. As our friend Leonardo da Vinci said in the year 1500: "He who wishes to be rich in a day will be hanged in a year."

Over the past several years, New York stocks have averaged 30% annual returns, but don't count on this Continuing. While it's true that since the year 1900, stocks have averaged an 11% annual rem. It's a roller-coaster ride with many minus years as well, so you have to stay in for the long term-you have to weather the storm-and not be too greedy.

(30)

A．To develop a savings plan.

B．To set up a bank account.

C．To set clear investing goals.
