问答题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.

问答题那时河里热闹极了；船大半泊着，小半在水上穿梭似的来往。停泊着的都在近市的那一边，我们的船自然也夹在其中。因为这边略略的挤，便觉得那边十分的疏了。在每一只船从那边过去时，我们能画出它的轻轻的影和曲曲的波，在我们的心上；这显示着是空，且显着是静了。那时处处都是歌声和凄厉的胡琴声，圆润的歌喉，确乎是很少的。但那生涩的，尖脆的调子能使人有少年的，粗率不拘的感觉，也正可快我们的意。况且多少隔开些儿听着，因为想象与渴慕的作美，总觉得更有滋味：而竞发的喧嚣，抑扬的不齐，远近的杂沓，和乐器的嘈嘈切切，合成另一意味的谐音，也使我们无所适从，如随着大风而走。这实在因为我们的心枯涩已久了，变为脆弱；故偶然润泽一下，便疯狂似的不能自主了。
