听力原文：M: Math department, Doctor Webster speaking.
W: Hello, Prof. Webster, this is Janet Hill calling. I lived two doors down from your teaching assistant, Don Williams. Don asked me to call you because he has lost his voice and can't talk to you himself.
M: Lost his voice？ Oh, what a shame! Is there anything I can do for him？
W: Well, he has a class this afternoon from 2: 30 to 4:00 and he won't be able to teach it. But he doesn't want to cancel it, either.
M: Does he want me to try to find somebody else to teach the class？
W: No, not exactly. What he wants to do is to get someone to go in for him, just to pass back the midterm exams. He's already marked them and they are on the desk in his office. The whole thing wouldn't take more than ten minutes.
M: His class is at 2: 30, you say？ Well, I'm free at that time and I was going to be on campus anyway; so I could do it for him. What room is his class in？
W: Cater Hall, Room two-fourteen. Will you need his office key to get the exams7 He's given it to me and I could bring it to you.
M: Actually, that won't be necessary. We have a master key in the math department. So I can get into his office if necessary.
W: Thank you very much, Prof. Webster. Don doesn't have another class to teach until Thursday, and hopefully, he will be able to talk by then. He'll call you as soon as he can. Oh, yes, I almost forget.
M: Yes？
W: Could you put the next assignment on the board, too？ It's all the problems on Page 45,and they are due at the next class.
M: No trouble at all. Thank you for passing on all the news about Don, and please tell him not to worry about anything.

听力原文： The period of engagement is the time between the marriage proposal and the wedding ceremony. Two people agree to marry, when they decided to spend their lives together. The man usually gives the woman a diamond engagement ring. That tradition is said to have started when an Austrian man gave a diamond ring to the woman he wanted to marry. The diamond represented beauty. He placed it on the third finger of her left hand. He chose that finger because it was thought that the blood vessel in that finger went directly to the heart. Today we know that this is not true, yet the tradition continues.
Americans generally are engaged for a period of about one year, if they are planning a wedding ceremony and a party. During this time, friends of the bride may hold a party at which women friends and family members give the bride gifts that she will need as a wife. These could include cooking equipment or new clothing. Friends of the man who is getting married may have a bachelor party for him. This usually takes place the night before the wedding. Only men are invited to the bachelor party.
During the marriage ceremony, the bride and her would-be husband usually exchange gold rings that represent the idea that their union will continue forever. The wife often wears both the wedding ring and the engagement ring on the same finger. The husband wears his ring on the third finger on his left hand. Many people say the purpose of the engagement period is to permit enough time to plan the wedding. But the main purpose is to let enough time pass so the two people are sure that they want to marry each other. Either person may decide to break the engagement, if this happens, the woman usually returns the ring to the man. They also return any wedding gifts they have received.

The following examples show the truth of this law.
(a) Put a table-cloth on a table and arrange a pile of books on it. Hold one edge of the table-cloth and pull it quickly. The table-cloth will come off, leaving the pile of books undisturbed.
(b) Place a small piece of cardboard on an open jar and place a coin on it directly over its mouth. Use one finger to flick the piece of cardboard away. You will notice that the coin drops into the jar.
(c) Sitting in a car which starts suddenly, you feel you are jerked backwards. In fact, you are not jerked backwards. Your lower half, which is in contact with the cushion, is forced to move forward with the car, and the upper part of your body, which remained at rest, is left behind.

Highways
Early in the 20th century, most of the streets and roads in the U.S. were made of dirt, brick, and cedar wood blocks. Built for horse, carriage, and foot traffic, they were usually poorly cared for and too narrow to accommodate(容纳)automobiles.
With the increase in auto production, private turnpike(收费公路)companies under local authorities began to spring up, and by 1921 there were 387,000 miles of paved roads. Many were built using specifications of 19th century Scottish engineers Thomas Telford and John MacAdam(for whom the macadam surface is named), whose specifications stressed the importance of adequate drainage. Beyond that, there were no national standards for size, weight restrictions, or commercial signs. During World War I, roads throughout the country were nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919, after serving in the U. S. Army's first transcontinental motor convoy(车队), he noted: "The old convoy had started me thinking about good, two-lane highways, but Germany's Autobahn or motorway had made me see the wisdom of broader ribbons across the land."
It would take another war before the federal government would act on a national highway system. During World War II, a tremendous increase in trucks and new roads were required. The war demonstrated how critical highways were to the defense effort. Thirteen per cent of defense plants received all their supplies by truck, and almost all other plants shipped more than half of their products by vehicle. The war also revealed that local control of highways had led to a confusing variety of design standards. Even federal and state highways did not follow basic standards. Some states allowed trucks up to 36,000 pounds, while others restricted anything over 7,000 pounds. A government study recommended a national highway system of 33,920 miles, and Congress soon passed the Federal-Aid Highway Act of 1944, which called for strict, centrally controlled design criteria.
The interstate highway system was finally launched in 1956 and has been hailed as one of the greatest public works projects of the century. To build its 44,000-mile web of highways, bridges, and tunnels, hundreds of unique engineering designs and solutions had to be worked out. Consider the many geographic features of the country: mountains, steep grades, wetlands, rivers, deserts and plains. Variables included the slope of the land, the ability of the pavement to support the load, the intensity of road use, and the nature of the underlying soil. Urban areas were another problem. Innovative designs of roadways, tunnels, bridges, overpasses, and interchanges that could run through or bypass urban areas soon began to weave their way across the country, forever altering the face of America.
Long-span, segmented-concrete, cable-stayed bridges such as Hale Boggs in Louisiana and the Sunshine Skyway in Florida, and remarkable tunnels like Fort McHenry in Maryland and Mt. Baker in Washington, met many of the nation's physical challenges. Traffic control systems and methods of construction developed under the interstate program soon influenced highway construction around the world, and were invaluable in improving the condition of urban streets and traffic patterns.
Today, the interstate system links every major city in the U. S. , and the U. S. with Canada and Mexico. Built with safety in mind, the highways have wide lanes and shoulders, dividing medians or barriers, long entry and exit lanes, curves engineered for safe turns, and limited access. The death rate on highways is half that of all other U. S. roads(0.86 deaths per 100 million passenger miles compared to 1.99 deaths per 100 million on all other roads).
By opening the North American continent, highways have enabled consumer goods and services to reach people in remote and rural areas of t
