The first breath-taking pictures of the Earth taken from space showed it as a solid ball covered by brown land masses and blue-green oceans. We had never seen the Earth from that distance before. To us, it appeared as though the Earth had always looked that way and always would. Scientists now know, however, that the surface of the Earth is not as permanent (永久的) as we had thought.

Scientists explain that the surface of our planet is always moving. Continents moves about the Earth like huge ships at sea. They float on pieces of the Earth's outer skin. New outer skin is created as melted rock pushed up from below the ocean floor. Old outer skin is destroyed as it rolls down into the hot area and melts again.

Only since the 1960s have scientists really began to understand that the planet Earth is a great living machine. Some experts have said this new understanding is one of the most important revolutions in scientific thought. The revolution is based on the work of scientists who study the movement of the continents－a science called plate tectonics.

The modern story of plate tectonics begins with the German scientist Alfred Wegener. Before World War One, Wegener argued that the continents had moved and were still moving. He said the idea first occurred to him when he observed that the coastlines of South America and Africa could fit together like two pieces of a puzzle. He proposed that the two continents might have been one and then split apart.

Wegener was not the first person to wonder about the shape of the continents. About 500 years ago, explorers thought about it when they made the first maps of Americas. The explorers noted the east coast of North America and South America would fit almost exactly into the west coast of Europe and south Africa. What the explorers did not do, but Wegener did, was to investigate the idea that the continents move.

1.Which of the following is TRUE according to the passage?

A.The coastline of India and Africa fit together.

B.Our ancient thought that the surface of the earth is still.

C.Alfred Wegener was not the first person to investigate the idea that the continents move.

D.We didn't see the Earth from far away until we saw the picture taken in the space.

2.The last word of the third paragraph "tectonics" means" "______".

A.study of building B.study of the earth structure

C.study of the earth surface D.study of designing

3.What did the explorers find?

A.The east coastlines of North America and the west coast of Europe could fit together.

B.The coastlines of North America and Africa could fit together.

C.The coastlines of South America and Africa could fit together.

D.The coastlines of North America and India could fit together.

Space vegetables are grown from seeds(种子)that have been taken to space and brought back to the earth. The seeds are affected by the radiation(辐射)and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy.

Here are some facts that you should know about space vegetables.

Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat.

Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.

After genetically modified(转基因)food appeared in the market, people worried that they were eating unknown things. For example, if nut genes(坚果基因)are put inside potatoes, people allergic to nuts might get sick from eating these potatoes because they do not know they are also eating nuts. Unlike genetically modified food, space vegetables have not been genetically changed. This means that no new genes are put into the vegetables. Therefore, there are no dangers of eating something unknown.

1.Genetically modified food is different from space vegetables because it 　　　　 .

A. is grown in space

B. has nothing unknown

C. has been genetically changed

D. has no new genes

2.According to the passage, normal tomatoes can stay fresh for about 　　　　 days.

Eating in space is different from eating on the earth. The food that astronauts carry with them does not look like the food you eat.

Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship, the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag.

Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cakes often come in bite-size pieces.

Astronauts cannot drink water from open cups. The water would float in drops in the spaceship. The water is put in the special gun. The astronaut shoots the water into his mouth.

1.Some food carried in the closed bags by astronauts is ________.

A. cooked and frozen      B. full of water            C. raw

2.Astronauts can’t drink from open cups because__________.

3.The main idea of the passage is that __________.

Sarah stood in front of the mirror(镜子). “It looks like a raincoat on me,” she said.

“Perhaps the blue,” said Mama, gently.

“Sure,” the shopkeeper said. But when she took the blue coat, there on the shelf behind all of the dark coats, hidden like a spring flower in winter darkness, there, as if by magic, was a pink coat.

“A pink coat!” Sarah cried. “I want the pink coat.”

“That coat is smaller than the other ones,” Papa said.

Sarah spoke up. “I’m small, too. Papa, please let me try it on, Mama? Please?”

“It wouldn’t hurt to let her try it on,” Mama said.

Without a word, the shopkeeper took the coat from the shelf and held it for Sarah.

“Ohhh!” Sarah said. The coat was smooth and shiny inside like her sister Sylvia’s blouses. “Ahhh!”

Sarah stood very straight and looked in the mirror. She looked for a very long time. In the pink coat she looked like a spring flower.

“Sarah!” Mama said.

Sarah looked up. Mama was standing behind her. She was holding the brown coat.

“I’m afraid the pink coat will only fit one year,” Mama said, taking a step closer.

“And there’s no one to pass it on to,” said Papa.

And the shopkeeper said, “It’s wise to save money.”

Sarah backed away. No one was going to put her into a raincoat again. She wanted to be a flower.

“Sarah!” It was Papa. He came over to her. “You’re old enough to know that you can’t always have your own way,” he said seriously.

“Wise and true,” said the shopkeeper.

Sarah took off the pink coat, slowly.

“It is her colour, though,” Mama said.

“Ahh,” said the shopkeeper. “Anyone can see how the pink of the coat brings out the roses in her face.”

Papa looked thoughtful for a moment.

“We are lucky.” continued Mama, “that it is only one little coat for Sarah and not also new coats for Sylvia and Susan and Sally.”

Papa looked from the brown coat to the pink coat. “The cows will give milk soon enough,” he said “And how can we let Sarah wear a brown coat when she looks like a flower in this one?”

“Papa!” Sarah cried, putting on the pink coat back, quickly. She threw her arms around Papa’s neck. “　　 33　　 ” she whispered.

“Like a rose in spring,” Papa said.

1.What did Sarah try on first?

A. A big pink coat.　　 B. A small pink coat.　　 C. A big brown coat.　　 D. A small brown coat.

2.Why did Mama want Sarah to try brown and blue?

A. Because Sarah looked better in them.　　 B. Because Sarah could wear them longer.

C. Because they were big enough for Sarah.　　 D. Because they cost less than the pink one.

3.What did Sarah most probably say to Papa in the end?

A. How do I look?　　 B. How does the coat look?

C. I do look like a flower, don’t I?　　 D. The coat looks nice, doesn’t it?
