阅读理解 Passage 1 　　Manners evolved differently in different cultures. In earlier times there was a tendency for manners to become increasingly formal, and this was often viewed as progress. In the 18th and 19th centuries having good manners was seen as an important part of one’s education and social class, and it was necessary to be taken as a lady or a gentleman to get ahead in the world. 　　In the 20th and 21st centuries, manners have gradually become more relaxed and informal. The hosting of dinners and other social gatherings are no longer the exclusive privilege of the wealthy elite (精英), and private clubs are being gradually replaced by more open meeting places. So the manners of the salon (沙龙) are gradually combining with the manners of the pub. Clothing is a good indication of the changes in manners, as can be seen in the following examples. 　　It is surprising that the wearing of hats indoors by males is once again becoming acceptable. Students in North America often wear baseball caps to class. In many countries the wearing of hats indoors by males was once acceptable even in very polite society, but over the years this became considered as a lower-class behavior and was thus discouraged in both the middle and upper classes. The young people who wear hats indoors do not realize they are actually restarting a very old cultural tradition. 　　A comparable development for females is the wearing of jeans. Many females now wear jeans on a daily basis, either at home or at work. Some see this as a symbolic declaration that they are now modern women, not girls or ladies. Some girls, like boys, wear baseball caps both indoors and outdoors. 　　Sneakers and shorts are now acceptable for either males or females in a variety of non-athletic situations. Some companies have rules requiring informal dress such as jeans or sneakers on Fridays (called “dress-down Friday” or “casual Friday”), and others permit it almost all the time. In these companies, and many others, it is acceptable to call the bosses by their first names. 1 What does the passage mainly talk about?

The Robot Man

According to Hans Moravec, universal robots will take over all the physical activities that we engage in, leaving us with little housework to do. Moravec sees four generations on the road to true universal robots. The first generation will be here by 2010 and will consist of free-ranging robots that can navigate by building an internal mental map of their surroundings. In new situations they&39;ll be able to adapt, unlike today&39;s mobile industrial robots. These robots will have the computing power, to cope with simple speech and text recognition, and will be used for tasks such as domestic cleaning.

The second generation will arrive around 2020 and will be distinguished by the ability to learn.

Second generation robots are programed with sets of primitive tasks and with feedback that provide"pleasure" and "pain" stimuli. For example, a collision provokes a negative response, a completed task would be positive.

Move forward another ten years to 2030 and you get to generation three. This robot can build internal simulations of the word around it. Before beginning a task, it can imagine what will happen in order to predict problems. If it has a free moment, it can replay past experiences and try variations in order to fred a better way of doing things next time. It could even observe a person or another robot performing a task and learn by imitation. For the fast time, we have here a robot that can think.

By the time we get to generation four in 2040, Moravec predicts that robots will be able. to match human reasoning and behaviour, generalise abstract ideas from specific experience, and conversely,compile detailed plans of action from general commands such as "earn a living" or "make more robots".

(宣告 ) runs something like this. As robots start to become useful in

The Moravec manifesto generation one, they&39;ll begin to take on many tasks in industry. Driven by the availability of this cheap and tireless labour force, the economy will boom and the demand for robots will grow so rapidly that they will soon become low-cost commodity items, that they&39;ll move into the home,where the domestic robot will relieve us of lots of housework.

With increasing automation in generations two and three, the length of the average working day will plummet, eventually to near zero. Most people will be unemployed as robots take over not just primary industry, but the service economy too. Moravec sees the fourth generation as an opportunity to surpass (超越) our human limitations.

These future machines will be our "mind children". Like biological children of previous generations, they will embody humanity&39;s best hope for a long-term future.
