COOL INVENTIONS
From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go．This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy．Solar panels on the Eclectic's roof absorb sun rays when you're driving．On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked．The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged．Zipping (迅速行进) around the neighborhood has never been better.
Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries．There are two sets of metal electrodes (电极) inside the water tank．Water contains ions (离子) that carry negative and positive charges．These ions complete a charge between the electrodes, creating enough energy to power the clock．Just refill the tank every few weeks, and this clock will keep on ticking.
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier．(The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine．Then a rocket fires up, pushing the SSC past 1,000 miles an hour．In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle.
You're having a blast at your friend's birthday party．But when it's time to bring out the cake, everyone crowds around, blocking your view．No worries．Throw the Triops into the air, and this clever camera captures the view from above．The Triops can take three pictures at once, each from different angles．You can also record sounds and command the Triops to start shooting whenever it hears that noise．That's one smart camera.

A．is popular with businessmen B．is suitable for a long trip

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（惯例） in our country where we may be generous 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（常规）. 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!
46. The writer of this passage must be ______.
A. an American B. a Chinese C. a professor D. a student
47. Which of the following statements is TRUE according to the passage?
A. Friendships between Americans usually extend deeply into their families.
B. Friendships between Americans usually last for all their lives.
C. Americans always show their warmth even if they are very busy.
D. Americans will continue their friendships again even after a long break.
48. From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.
A. warmly welcomed at the airport
B. offered a ride to his home
C. treated hospitably at his home
D. treated to dinner in a restaurant
49. The underlined words “generous with our time” in Paragraph 3 probably mean ______.
A. strict with time B. serious with time
C. careful with time D. willing to spend time
50. A suitable title for this passage would probably be “______”.
A. Friendships between Chinese
B. Friendships between Americans
C. Americans’ hospitality
D. Americans’ and Chinese’s views of friendships
