Directions: Translate the following text into Chinese.
Cell phones may help busy executives keep in constant touch with important business associates, but they may also increase their risk of high blood pressure, preliminary research suggests. A study of 10 German mobfie phone users found that when they switched on their phone, their blood pressure shot up by 5 to 10 millimeters of mercury, researchers reported in this week’s issue of the international medical journal, The Lancet. Exactly how cell-phone use can lead to increases in blood pressure is unclear, but researchers speculate that the electromagnetic fields emitted by phones may somehow boost pressure. While the blood pressure increases found in the new study are small, they may be detrimental to people who already suffer from hypertension, researchers led by S. Braune of the Neurologische Universitateklinik in Freiburg, Germany, explained.

Food and Cancer
Medical experts have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of developing cancer. A team of Chinese and American scientists did the study. They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study. They were from the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.
Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus. Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate. Researchers divided those into eight groups. Seven of the groups received different mixtures of vitamins and minerals daily. The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed. The eighth group received sugar pills that had no effect. Those who seemed to gain the most received a mixture of a form. of vitamin A called β-carotene, vitamin E and the mineral selenium. The vitamin and mineral are believed to prevent damage to cells caused by cancer-causing substances. Researchers reported a 13 percent drop in cancer rates in those who took β-carotene, vitamin E and selenium. They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels.
Scientists warn that it is too soon to know if the effect would be the same among people in other countries. They note that the people in Linxian eat foods that lack necessary vitamins and minerals. Chinese officials will continue to record the health records of the people in Linxian for many years. For now officials reportedly are considering using the .results of the study. They want to find a way to improve the health of people in Linxian and other small towns in China.
The results of the new study are unexpected.
A．Right
B．Wrong
C．Not mentioned
