Jean--Francois Millet (October 4,1814----January 20, 1875) was a French painter and one of the founder of the Barbizon School in rural France. Born of a peasant family, Millet was encouraged by his father to study art in Cherbourg, France. He can be categorized as part of the movement called "naturalism" . His understanding of the peasant' hard life was perfectly expressed in his choice of subject and natural preference for powerful but simple drawing and coloring. One of the most well--known of Millet's paintings, The Gleaners(<<>> ),first came in a vertical composition  painted in 1854,and then there came the horizontal version in 1856, which is now preserved in the Musee d'Orsay. It depicts women bending over in the fields to collect the leftover's from the harvest, and it is a monumental composition devoted to the working class. Previously, servants were depicted in paintings as obedient to a noble or a king, and picking up what was left of the harvest was regarded as one of the lowest jobs in Millet;s times. However, Millet offered these women as the heroic focus of the picture. Besides, in the painting, light lights up the women's shoulders as they carry out their work. Behind them, the field that stretches into the distance is bathed in golden light, under a wide , magnificent sky. The forms of the three figures, standing against the lighter field, show balance and harmony. In the painting, the viewer can appreciate Millet's  _  .. A) crazy interest in blue color B) strong focus on the city life C) absolute respect for the king D) particular choice of main characters

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  . 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 45 showerheads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium. But Pace said that they _ 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  , he had some advice. Let the water run for 30 seconds 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  , 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   attack. From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because  _  . A) it's easy to get a cold when taking a bath B) the showerhead carries many bacteria causing illness C) we don't get cleaned while showering D) we don't get a weak immune system
