听力原文： A twenty-one-year-old American named Philo Farnsworth built the first working television receiver in nineteen twenty-seven. Many scientists around the world had made important discoveries that led to the development of television. But Philo Farnsworth had recognized as a boy that electrons could capture a picture sent as light and sound waves through the air.
Over the years, the technology has changed and improved. But the idea behind the television broadcast is still the same. TV stations send a powerful signal from a transmitting antenna. An antenna connected to a television set receives the signal.
The problem with this system is that the receiver antenna has to be in line with the transmitting antenna. Mountains or tall buildings can interfere. One solution is cable television.
This system began in the nineteen forties in Pennsylvania. Only a few television stations existed then, and they were in large cities. People in small towns could not receive the signals. So a store owner put an antenna on top of a pole and placed it on a nearby mountain. This antenna received the television signal. Wires led from the antenna to the store. The cable brought clear pictures to the television sets inside. Later, the idea of cable television spread to cities, to provide people with more stations to watch.
Today, people can watch hundreds of stations. And another way to receive them is with a satellite dish antenna. A small round device of the size of a pizza can receive signals from satellites .high above the Earth. The antenna is connected to a special receiver which connects to the television set. Some broadcasts over satellite can be watched free of charge. But the others cost money, just like cable service.
The passage mainly focuses on ______.
A．the importance of TV
B．the function of TV
C．the production of TV
D．the evolution of TV

听力原文： Listen as a guide describes the ancient art of thatching a roof.
Welcome to the Four Winds Historical Farm, where traditions of the past are preserved for visitors like you. Today, our master thatchers will begin giving this barn behind me a sturdy thatched roof able to withstand heavy winds and last up to a hundred years. How do they do it？ Well, in a nutshell, thatching involves covering the beams or rafters--the wooden skeleton of a roof--with reeds or straw. Our thatchers here have harvested their own natural materials for the job--the bundles of water reeds you see lying over there beside the barn.
Thatching is certainly uncommon in the United States today. I guess that's why so many of you have come to see this demonstration. But it wasn't always that way. In the seventeenth century, the colonists here thatched their roofs with reeds and straw, just as they had done in England. After a while, though, they began to replace the thatch with wooden shingles because wood was so plentiful. And eventually, other roofing materials like stone, slate, and clay tiles came into use.
It's a real shame that most people today don't realize how strong and long-lasting a thatched roof is. In Ireland, where thatching is still practiced, the roofs can survive winds of up to one hundred ten miles per hour. That's because straw and reeds are so flexible. They bend but don't break in the wind like other materials can. Another advantage is that the roofs keep the house cool in the summer and warm in the winter. And then, of course, there's the roofs' longevity—the average is sixty years, but they can last up to a hundred. With all these reasons to start thatching roofs again, wouldn't it be wonderful to see this disappearing craft return to popularity？
26. What is about to be demonstrated？
27.What are thatched roofs made of？
28.According to the speaker, why did thatching die out in the United States？
29.According to the speaker, why does thatch survive strong winds？
30.According to the speaker, how might thatching become popular again？
(26)
A．Putting a roof on a barn.
B．Harvesting water reeds.
C．Using stone as a building material.
D．Daily farm operations.

What could I do？ Ten minutes later I was ￡20 poorer; and the cupboard was tied on the roof rack. It was six feet long and eighteen inches square, quite heavy too.
In the gathering darkness I drove slowly. Other drivers seemed unusually polite that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea.
After a time my wife said，"There's a long line of cars behind. Why don't they overtake, I wonder？" In fact a police car did overtake. The two officers inside looked at us seriously as they passed. But then, with great kindness, they led us through the rush-hour traffic. The police car stopped at our village church. One of the officers came to me.
"Right, sir, "he said. "Do you need any more help？"
I was a bit puzzled. "Thanks, officer, "I said. "You have been very kind. I live just on the road."
He was staring at our car, first at the flowers, then at the cupboard. "Well, well, "he said, laughing. "It's a cupboard you've got there! We thought it was something else."
My wife began to laugh. The truth hit me like a stone between the eyes. I smiled at the officer. "Yes, it's a cupboard, but thanks again．"I drove home as fast as I could.
In fact the husband _______ the cupboard.
A．would like very much to buy
B．badly wanted
C．was glad to have bought
