问题     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 mobile 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.
选项
答案 一项初步的研究表明，手机可以帮助忙碌的经理们和重要的商务伙伴保持及时联系，但是使用手机也有可能增加他们患高血压的危险。对德国的10名手机使用者的研究发现，当他们打开手机时，他们的血压瞬时升高 5～10毫米血压计水银柱，研究人员在本周出版的国际医学杂志《柳叶刀》上如是说。手机如何导致血压升高的确切理由尚不清楚，但是研究人员推测，可能是手机发出的电磁场使得血压升高。德国弗兰堡垒大学神经病学研究所的S勃劳恩领导的研究人员解释说，尽管在这项新的研究中发现的手机导致的血压升高微不足道，但对那些已经患高血压的人来说，可能是有害的。
