About Environment The passage mainly discusses that people decide to adopt several methods to prevent birds from flying through the glass and get hurt. However, the lecture takes a opposite viewpoint which is different from the writer’s opinion. First, in the reading passage, one measure is presented the regular glass can be replaced by one- way glass to prevent birds from flying through the windows. Nevertheless, the professor argues about this point in the listening. As a matter of fact, the one-way glass has the same effect as regular glass. Birds will regard the one-way glass as mirrors because they do not understand it. When they see the reflection of trees and sky reflected in the glass, they may think the reflections are the real things and they will still fly through the glass. So this way is not an effective solution. Moreover, the writer in the reading passage points out that the regular glass with colorful lines or other designs which people can see the scene through the blank place can make birds avoid flying across when they see the lines. In contrast, the speaker in the listening mentions that the result can be different. The birds may regard the blank parts of the glass as open holes and fly into the rooms. Additionally, if people make the no painting place so small that the birds’ sizes are not tiny enough to fly though. The problem is that there will be not enough sunshine and the room may be too dark. Therefore, this measure does not work. Finally, the reading passage states that birds can be guided away from buildings by artificial magnetic equipment because birds need magnet to navigate. On the contrary, ,the professor in the listening material contends that his point is unconvincing neither. Actually, birds will use their magnetic ability to navigate just in the long distance such as they travel from a cold country to a warm country in winter. In the short distance like from one side of a city to another side, they only use their eyes and brightness of light to distinguish the direction. As a result, the magnetic structures are useless in cities.
