One of Britain's bravest women told yesterday how she helped to catch suspected police killer David Bieber—and was thanked with flowers by the police. It was also said that she could be in line for a share of up to £ 30,000 reward money.
Vicki Brown, 30, played a very important role in ending the nationwide manhunt. Vicki, who has worked at the Royal Hotel for four years, told of her terrible experience when she had to steal into Bieber's bedroom and to watch him secretly. Then she waited alone for three hours while armed police prepared to storm the building.
She said： “I was very nervous. But when I opened the hotel door and saw 20 armed policemen lined up in the car park I was so glad they were there. ”
The alarm had been raised because Vicki became suspicious （怀疑的）of the guest who checked in at 3 pm the day before New Year's Eve with little luggage and wearing sunglasses and a hat pulled down over his face. She said： “He didn't seem to want to talk too much and make any eye contact. ” Vicki, the only employee on duty, called her bosses Margaret, 64, and husband Stan McKale, 65, who phoned the police at 11 pm.
Officers from Northumbria Police called Vicki at the hotel in Dunston, Gateshead, at about 11:30 pm to make sure that this was the wanted man. Then they kept in touch by phoning Vicki every 15 minutes.
“It was about ten past two in the morning when the phone went again and a policeman said 'Would you go and make yourself known to the armed officers outside?' My heart missed a beat. ”
Vicki quietly showed eight armed officers through passages and staircases to the top floor room and handed over the key.
“I realized that my bedroom window overlooks that part of the hotel, so I went to watch. I could not see into the man's room, but I could see the passage. The police kept shouting at the man to come out with his hands showing. Then suddenly he must have come out because they shouted for him to lie down while he was handcuffed （戴上手铐）
1.Vicki became suspicious of David Bieber because ______ .

Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years.
Scientists know that Earth formed about 4. 5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust (地壳), eventually formed moving plates. Exactly when this shift happened, however, is an open question.
Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3. 8 billion years ago. The new estimate is 1. 3 billion years earlier than previous ones.
Not long before 3. 8 billion years ago, lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface.
In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal (上地壳) belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air.
The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks (裂缝) in the rock that have been filled in with a type of volcanic rock.
To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today.
That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under the ocean, beginning around 3. 8 billion years ago.
“It's a fantastic case of solving a jigsaw puzzle (拼图),” says one of the researchers. He notes that the puzzle was “ a very difficult one because these rocks are all very old and have been badly ruined".
1.What can we infer from the text?
A.The shapes of continents and oceans changed slowly.
B.The Earth's crust started shifting 1. 3 billion years ago.

2.What do scientists know about the past of the Isua supracrustal belt?
A.It was once covered by the hot, liquid rock.
B.It remained under the deep sea.
C.It stayed hot and sinking.
D.It kept moving slowly.
3.The underlined phrase “oozed from” in Paragraph 7 is closest in meaning to

C.flew out of slowly D.broke through suddenly
4.The text is mainly about .
A.why the Earth cooled
B.how the Isua supracrustal belt formed

Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or eDNA for short. Scientists can use it to identify rare species or estimate fish populations with just a little air or water.
Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature.
Caren Goldberg is one of the first biologists to take the technology from the testing stage to actually using it. She sees eDNA as a way to get answers more efficiently and with less destruction compared to traditional survey techniques. Until recently, scientists depended on snorkeling ( 潜水), netting or using an electric current to temporarily catch fish.
This newer way to identify what lives in the environment is becoming popular around the world. Animal experts in Vietnam are using the eDNA to find the last, wild Yangtze giant softshell turtles. One researcher on the Caribbean island of Trinidad is using the sampling technology to find endangered golden treefrogs. In Madagascar, it is being used to identify amphibian(两栖动物)diseases.
Ms Goldberg has used eDNA testing to confirm the local extinction (灭绝) of a leopard frog in the American state of Idaho. She has also been asked to document the spread of the New Zealand mudsnail in the state of Washington. The creature has been found in lakes and other waterways across the state.
Scientists working with the technology say they do not expect robots to replace field biologists anytime soon. But the old-fashioned field work could soon be more targeted.
1.Compared to traditional survey techniques, eDNA is more______.
A.complex B.eco-friendly
C.dangerous D.convincing
2.By using eDNA, Caren Goldberg has______.
A.succeeded in catching many fishes
B.found the existence of golden treefrogs
C.documented the spread of softshell turtles
D.confirmed the disappearance of the leopard frog in Idaho
3.What can we infer from the last paragraph ?
A.Robots will replace scientists soon.
B.Some scientists are against using eDNA.
C.The old-fashioned field work may disappear.
D.Many biologists are unwilling to do the field work.
4.What is the best title for the text?
A.Science Fiction Becomes Reality for Species Surveys
B.Biologists Explore Space with the Help of eDNA
C.Scientists Found Methods to Test for Signs of Life
D.New Technologies Are Presented in Science Fictions

Over the past few decades, more and more countries have opened up the markets, increasingly transforming the world economy into one free-flowing global market. The question is: Is economic globalization _______ for all?
According to the World Bank, one of its chief supporters, economic globalization has helped reduce ___________ in a large number of developing countries. It quotes one study that shows increased wealth _________ to improved education and longer life in twenty-four developing countries as a result of integration (融合) of local economies into the world economy. Home to some three billion people, these twenty-four countries have seen incomes _______ at an average rate of five percent—compared to two percent in developed countries.
Those who _______ globalization claim that economies in developing countries will benefit from new opportunities for small and home-based businesses. _______, small farmers in Brazil who produce nuts that would originally have sold only in _______ open-air markets can now promote their goods worldwide by the Internet.
Critics take a different view, believing that economic globalization is actually _______ the gap between the rich and poor. A study carried out by the U.N.-sponsored World Commission on the Social Dimension of Globalization shows that only a few developing countries have actually _______ from integration into the world economy and that the poor, the uneducated, unskilled workers, and native peoples have been left behind. ____________, they maintain that globalization may eventually threaten emerging businesses. For example, Indian craftsmen who currently seem to benefit from globalization because they are able to ____________ their products may soon face fierce competition that could put them out of ____________. When large-scale manufacturers start to produce the same goods, or when superstores like Wal-Mart move in, these small businesses will not be able to ____________ and will be crowded out.
One thing is certain about globalization—there is no ____________. Advances in technology combined with more open policies have already created an interconnected world. The ____________ now is finding a way to create a kind of globalization that works for the benefit of all.

Finding Your Courage
Gold and brown leaves crunched（吱吱响）under Dora's boots as she made her way down the sidewalk. She could not wait to be home. The chill（寒冷）from the autumn winds was bad, but it was not nearly as hard to bear as the chill she felt in her heart.
She could not forget the way she had frozen in front of the class today. Mr. Roberts divided the class into groups to do presentations. Each person in the group would speak for five minutes in front of the class. Today was Dora's turn. Her legs trembled（颤抖）all the way to the front of the classroom. Her hands shook so badly that she could not read her notes. As Dora spoke, her voice became softer, almost to silence. Mr. Roberts kindly ended Dora's part of the presentation even though she had clearly not finished. He also asked Dora to stay after class for a moment.
“Dora, I know you're shy, but you worked hard on this project. I'd hate to see you give up on yourself. ” Mr. Roberts suggested, “If I give you another chance tomorrow, do you think you can find your courage?”
Dora nodded. She went as quickly as she could to her next class. She kept her head down and hoped the school day would end soon.
Arriving home, she found Mom baking in the kitchen. When Mom baked, Dora always watched and chatted with her. Mom always said it was Dora's company that made her baked goods taste so sweet.
Mom studied Dora's face as she came into the kitchen. “What's wrong, Dora?"
Tears shone in Dora's brown eyes. She told the whole story. Mom was silent for a moment, but her hands still busy with the cake.
“Why is it that you can talk to me about anything and everything, but you can't talk to your class?" Mom asked, sliding the round cake pans into the oven. She set the timer and then said, “Let me show you something. ”
Paragraph 1:
Dora followed Momma to her bedroom.

Paragraph 2:
The next day Dora again walked to the front of the classroom to give her presentation.
