But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least'a few decisions for themselves-goals that pose a real challenge.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily. Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may begenerous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably. For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home! 1.The writer of this passage must be a Chinese.() 2. Americans will continue their friendships again even after a long break.() 3.From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be warmly welcomed at the airport.() 4.The underlined words “generous with our time” in Paragraph 3 probably mean willing to spend time. 5.A suitable title for this passage would probably be “Americans’ and Chinese’s views of friendships”.()

A. Router A must have a Level 2 adjacency with the Level 1/Level 2 router in area 49.0001. B. The Level 1/Level 2 router in area 49.0001 sets the &quot;attached&quot; bit in the Level 2 LSP it floods into area 49.0001. C. The Level 1/Level 2 router in area 49.0001 sets the &quot;attached&quot; bit in the Level 1 link-state PDU (LSP) it floods into area 49.0001. D. The Level 1/Level 2 router in area 49.0001 advertises these prefixes into area 49.0001 using a Level 2 LSP it floods into the area.
