A new eight-kilometer road is under construction that links the port area with motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometer road tunnels are being built below the central area of the city, one for traffic to the north and the other for the traffic to the south. The two tunnels are about 20 meters below the surface and are 12 meters wide, providing for two lanes of traffic in each direction.
In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electric signs at frequent intervals. They show traffic conditions ahead and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and, on the inside of the tunnel, a concrete lining（混凝土衬砌）.
Each tunnel is roughly round and the lower part of the tunnel is somewhat flat. The surface of the road lies on the base, which is made of concrete and steel. The drainage system, just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel and at the level of the road surface. Other systems in the tunnel will include emergency phones.
72. Each of the tunnels under construction is _____.
A. eight kilometers long and twenty meters wide B. eight kilometers long and six meters wide
C. four kilometers long and twenty meters wide D. four kilometers long and six meters wide
73. Which part of the tunnel in the diagram is used to pipe out extra water?
A. 1 B. 3 C. 5 D 6
74. Driving in the tunnel, one can know the traffic conditions ahead through______.
A. the lights B. the electric signs
C. the trucks and the cars D. the emergency phones
75. The passage is mainly about _____.
A. the construction of a road B. the design of a road
C. the construction of two tunnels D.the design of two tunnels
The Donkey Mobile Library
It is a bright morning in the Ethiopian countryside. Yohannes walks beside a pair of donkeys that are pulling a two-wheeled cart. They arrive at the agricultural town of Awassa where Yohannes opens the sides of the cart to display, not the usual vegetables or tools, but children’s books. This is the Donkey Mobile Library, the first of its kind in Ethiopia and one of only a few in the world.
Yohannes was born in Ethiopia, North Africa, but trained to be a librarian in the USA and returned to Ethiopia years ago. The cart is full of picture books donated by American libraries, teachers and school children.
Yohannes arranges small painted benches in the shade of the trees, and suddenly Ethiopian children come shouting and racing down every road and path. It’s mobile library day! They circle the bookshelves with great excitement. Until the Donkey Mobile Library began its regular two-monthly visits, many of these children had never seen a book.
“Without books, education is very dull, like food without salt. You can survive but you can’t really come alive,” says Yohannes. “The ability to read is the basis for greater productivity, better health and longer life. Even though the children lack material goods, with books they can imagine a world of possibilities.”
Yohannes first worked in the children’s section of the main library in America. Surrounded by books he had never seen before, he realized how joyful and imaginative children’s literature is. He says, “I always thought of Ethiopia. But how could I bring children’s books to my home country when it had almost no libraries to keep the books in?”
He contacted Jane Kurtz, a writer born in America but brought up in Ethiopia, and together they created the Donkey Mobile Library. The children say that the Library has given them ideas about what they might do in the future. A child called Dareje wants to be a scientist and find a cure for life-threatening diseases. An eleven year-old girl, Fikerte, wants to do research about the moon and discover new facts about outer space. Tamrat, aged 10, comes every time.
“What brings you back here time and time again?” the librarian asks him.
“The stories,” Tamrat replies instantly.How do the children feel when they see the Donkey Mobile Library?

Science, as we think, was born when the Greek philosopher (哲学家) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe?
No one had a ready answer, so Thales went on studying the earth around him, the sky and the stars. He saw so much water on earth and so much water falling from the sky as rain that he decided water must be the basic substance (物质) of the universe.
Other Greek thinkers became interested in this question. They suggested other answers. One said that because air lies around the earth, it must be air that makes up all things. Another said that fire, appearing in different forms, was the building block of the universe.
The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances. But the list is much more complicated than the Greeks realized. We now know of 103 basic substances which we call “ elements (元素)”.Thales, the famous Greek philosopher, died when he was about_________.

“Fire! Fire!” What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke.

The floor became hot under my bare feet. I found an open door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me.
I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street.

There are about fifteen hundred languages in the world. But 21 a few of them are very 22 . English is one of these. Many, many people use it, not only in England and the U.S.A., but in other parts of the world. About 200,000,000 speak it as their own language. It is difficult to say how many people are learning it as a 23 language. Many millions are 24 to do so.
Is it easy or difficult to learn English? Different people may have different 25 . Have you ever 26 ads of this kind in the newspapers or magazines? “Learn English in six weeks, or your 27 back.”.“Easy and funny! Our records and tapes 28 you master(掌握) your English in a month. 29 the first day your 30 will be excellent. Just send us ... ” Of course, it never 31 quite like this.
The only language that seems easy to learn is the mother tongue. We should 32 that we all learned our own language well when we were33 . If we could learn English in the sameway, it would not seem so difficult. 34 what a small childdoes. He listens to what people say. He tries what he hears. When he is using the language, talking in it, 35 in it allthe time. Just imagine how much 36 that gets!
