Man&39;s first real invention, and one of the most important inventions in history, was the wheel. All transportation and every machine in the world depend on it. The wheel is the simplest yet perhaps the most remarkable of all inventions, because there are no wheels in nature-no living thing was ever created with wheels. How, then, did man come to invent the wheel？ Perhaps some early hunters found that they could roll the carcass of a heavy animal through the forest on logs more easily than they could carry it. However, the logs themselves weighed a lot.
It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick. This would roll along just as the logs did, yet be much lighter and easier to handle. Thus the wheel and axle came into being and with them the first carts.
1、The wheel is important because__________.
A.it was man’s first real invention
B.all transportation depends on it
C.every machine depends on it
D.both B and C
It was remarkable of man to invent the wheel because__________.A.it led to .many other inventions
B.man had no use for it then
C.there were no wheels in nature
D.all of the above
The wheel was probably invented by__________.A.a group of early hunters
B.the first men on earth
C.a great prehistoric thinker
D.the man who made the first cart
The wheel is called__________.A.simple
B.complicated
C.strange
D.unusual

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.
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”.()
