14.It is generally believed that we are getting cleaned when we step under a shower.We are,but we're also giving a home to lots of tiny little creatures we didn't even know about.A showerhead carries thousands of bacteria called Mycobacterium.These can cause problems like coughs and tiredness,and a general feeling of poorliness (身体不舒服).When you turn on the water,the bacteria go from the showerhead onto and into your body.This is a finding of Norman R.Pace and his team at the University of Colorado,in the US.The scientists investigated bacteria in all kinds of human environment,including showers.Pace's team looked at 45showerheads in nine American cities.They discovered that 30percent of them had large amounts of flying Mycobacterium.
But Pace said that they pose few threats to the health.Only those with a weak immune system might need to worry.He told the New York Times that the bacteria are not as unpleasant as might be thought.He said that having a shower is no more dangerous than anything else we do in the morning.
But for those who feel sick about the idea of all those microorganisms (微生物),he had some advice.Let the water run for 30seconds before getting into the shower.Why?The number of bacteria is smaller than that when the water is just turned on.If that seems like a waste of water,he added that you could also change your showerhead every few months.
However,Pace had good news too.He has also been testing the air in US subways.Apart from iron particles (粒子),which are ground off the track by the wheels of trains,subway air is fresh.The reason is that a train's movement pumps fresh outdoor air into the tunnels.
Pace explained that he wanted to understand the natural microbial environments of public places.This kind of knowledge might help discover the microbes to be used in a bioterrorist (生物恐怖分子) attack.

分析 本文主要介绍了Norman R.Pace和他的团队发现的结果,大多数淋浴头含有致病的细菌,但是这不会对人的健康有危害,但是免疫力差的人要注意,他还研究了美国的地铁,结果发现,地铁里面的空气是新鲜的.
解答 56.B 细节理解题.根据第一段A showerhead carries thousands of bacteria called Mycobacterium.These can cause problems like coughs and tiredness,and a general feeling of poorliness (身体不舒服).可知根据Norman R.Pace 的发现,我们在洗过澡后会感冒会咳嗽,因为淋浴头会携带很多致病的细菌.故选B.
57.D 细节理解题.根据第四段But for those who feel sick about the idea of all those microorganisms (微生物),he had some advice.Let the water run for 30seconds before getting into the shower.Why?The number of bacteria is smaller than that when the water is just turned on.可知淋浴水在流了30秒后,细菌就少多了.故选D.
58.C 推理判断题.根据第三段Only those with a weak immune system might need to worry.可知对免疫力强的人没有必要害怕微生物.故选C.
59.A 词义辨析题.根据第三段But Pace said that they pose few threats to the health.可知这些微生物对健康几乎不能造成威胁.所以pose相当于cause.故选A.
60.A 细节理解题.根据第五段Apart from iron particles (粒子),which are ground off the track by the wheels of trains,subway air is fresh.The reason is that a train's movement pumps fresh outdoor air into the tunnels.可知美国的地铁里面,火车的运动对新鲜空气是有帮助的.故选A.
