Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鯊魚).
Research by a British biology student suggests that sharks could be used to predict storms.
Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure.
If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.
Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal(潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic(模擬) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.
小題1:The passage is most probably taken from _____.
A.a short-story collectionB.a popular science magazine

Directions: Complete the following passage by using ONE word that best fits the context.
Thanksgiving Day was near. The first grade teacher gave her class   48  fun assignment --- to draw a picture of something for which they were thankful.
Most of the class would celebrate the holiday with turkey and other traditional goodies of the season. These, the teacher thought, would be the themes of most of her students’ art. And they were. Douglas made a different kind of picture,   49 . When asked to draw a picture of something for which he was thankful, he drew a hand. Nothing else. Just an  50  hand .
His abstract image captured the imagination of his peers. Whose hand could it be? One child guessed it was the hand of a farmer, because farmers raise turkeys.   51  suggested a police officer’s, because the police protect and care   52  people. Still others guessed it was the hand of God, for God feeds us. And so the discussion went --- until the teacher almost forgot the young artist himself.
When the children had gone on to other assignments, she stopped at Douglas’ desk, bent down, and asked him 53  hand it was. The little boy looked away and said, “It’s yours, teacher.”
She recalled the times she had taken his hand and walked with him here or there, as she had the other students. How  54  had she said, “Take my hand, Douglas, we’ll go outside.” Or, "Let me show you how to hold your pencil.” Or, “Let's do this together.” Douglas was most thankful for his teacher's hand. Brushing aside a tear, she went on with her work.
The story speaks of more than thankfulness. It says something about teachers teaching and parents parenting and friends showing friendship, and how much it means to the Douglases of the world. They might not always say thanks,  55  they'll remember the hand that reaches out.

I am so worried about global warming. We need stop cutting down all of the trees so that they can absorb the carbon dioxide. I think the Kyoto Protocol(京都議定書) to stop pollution is a great idea ,and I hope our country will decide to follow it, too.
— Eli S.,10,Texa
People should do all they can to help stop pollution, even if it is something as little as recycling your soda can. Every little thing helps. Maybe schools can put recycling bins in classrooms. Students can bring in all of their cans and bottles and see how many the school can collect.
— Lindsey A.,11, Massachusett
The United States should take action to help stop pollution. Since we are one of the richest countries, we should at least spend a little money to help.
— Aaron z,11,Massachusett
It is not good that the United States is not following the Kyoto Protocol. The U.S. is one of the most pollution emitting (污染物排放)countries in the world. Even if the rest of the world agrees to follow those rules, without the U. S. and its big businesses agreeing, global warming will still be a big problem.
—Augustine S.,11,Ohio
The world needs to learn more about global warming problems. If we do not do something soon then some of Earth’s coolest animals will become extinct. People should use solar power instead of things that pollute the atmosphere!
— Jillian J.,10,Pennsylvania
Global warming is very dangerous, and it must be prevented. Even if people think that it cannot be stopped ,we should  at least try. Stopping global warming is more important than keeping our businesses going. What about the penguins(企鵝)and the polar bears? We can’t just let them become extinct.
—Samantha R.,11,Illinois
小題1:Why does Lindsey suggest schools put recycling bins in classrooms?
A.To keep the classroom cleanB.To help protect wild animals.

In some remote Turkish village of Kuskoy, whistling is as important as talking.In fact, whistling is talking because the villagers speak and sing by whistling.Kuskoy parents begin to teach their boys and girls the language of whistling about the time the children learn to talk.It is considered so important that the village school includes it as one of the subjects taught along with the Turkish language.
This art of communication has taken centuries to develop.The village of Kuskoy spreads out across two hillsides that are separated by a deep valley.The villagers had to find an easy way to communicate where their voices couldn’t carry.They developed a high-pitched (高音的) whistle language that could be transmitted as far as five miles through air.As a result, Kuskoy, which means “bird village” in Turkish, has come to be known as a whistler’s paradise (樂園).
Whistling is so much part of everyday life in Kuskoy that men and women speak, argue, and court (求愛) in whistles.The story was recently told of a young couple who ran away secretly.The news was sent over the “mountain telephone” by whistling.The lover’s adventure was quickly known to all the villagers.
It is little wonder, then, that the children of Kuskoy study whistling in school.Wouldn’t it be fun to start the school day with a song—whistled of course!
小題1:The children of Kuskoy learn to whistle because __          _.
A.it is funB.it is an important way to communicate

Everyone has good days and bad days.
Sometimes, you feel as if you’re on top of the world. But occasionally you feel horrible, and you lose things and you cannot focus on your schoolwork.
For more than 20 years, scientists have suggested that high self-esteem (自尊) is the key to success. Now, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something.
“Forget about self-esteem,” says Jennifer Crocker, a psychologist (心理學家) at the University of Michigan, US. “It’s not the important thing.”
Feeling good
Crocker’s advice may sound a bit strange because it is good to feel good about yourself.
Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, or lonely than those with low self-esteem.
But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person.
He believes that violent and wicked people often have the highest self-esteem of all. He also said: “There’s no evidence that kids with high self-esteem do better in school.”
Problems
All types of people have problems. People with high self-esteem can have big egos (自我) that can make them less likeable to their peers(同齡人), said Kathleen Vohs, a psychology professor at Columbia University.
People with high self-esteem tend to think more of themselves, Vohs says. People with low self-esteem are more likely to rely on their friends when they need help.
What to do
Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something try to learn from the experience. “The best therapy (藥方) is to recognize your faults,” Vohs says. “It’s OK to say, ‘I’m not so good at that,’ and then move on.”
小題1:The new research comes to the conclusion that high self-esteem ________.
A.is not important at allB.has taken on a different meaning
C.may not be the key to successD.does not help you do better at school
小題2:One of the conclusions of the new research is that ________.
A.feeling good about oneself doesn’t mean you lead a happier life
B.people with high esteem usually do not seek other’s help
C.people with high esteem tend to be proud
D.people with low esteem are often more popular
小題3:The underlined part “a better person” in the passage probably means a person who is ________.
A.helpful and supportiveB.gentle and modest
C.likable and successfulD.friendly and kind
小題4:From the text, we can infer the best therapy mentioned in the last paragraph is mainly for people ________.
A.with high self-esteemB.with low self-esteem
C.of all kindsD.who are focusing on building self-esteem

We have all experienced days when everything goes wrong. A day may begin well enough, but suddenly everything seems to get out of control. It seems as if a single unimportant event may cause a number of things to happen. Let us suppose that you are preparing a meal and keeping an eye on the baby at the same time. The telephone rings and this means your troubles are beginning. While you are on the phone, the baby pulls the table-cloth off the table, destroying your prepared meal.

Things can go wrong on-a number of people on the road. During the rush hour one evening, two cars hit each other and both drivers began to argue. The woman driver behind the two cars happened to be a learner. She suddenly went into a panic and stopped her car. This made the driver following her stop suddenly. His wife was sitting beside him holding a large cake. As she was thrown forward, the cake went right through the window and landed on the road’. Seeing a cake-flying through the air, a truck driver had to stop his truck all of a sudden. The truck was carrying empty beer bottles and hundreds of them slid off the back of the truck and fell onto the road. This led to yet another angry argument. Meanwhile, the traffic piled up behind. It took the police nearly an hour to get the traffic to move again. In the meanwhile, the truck driver had to sweep up hundreds of broken bottles.

閱讀理解(時間:20分鐘)
A
Many years ago my student asked me the question, "Mrs. Kindred, why do you teach?" Without taking time to reflect, I answered, "Because someday I might say something that might make a difference in someone's life." Even though I was sincere, that wasn't a very good answer and my student didn't let it slide.
"Let me get this straight," he said, "You went to college for four years so you could come here every day because you have the hope that someday you might say something that will influence someone?" He shook his head as if I were crazy and walked away looking confused. I'm one of those people who look back and wish they had said something smart or witty, or swift.
Even though that particular student might no longer wonder why I teach, there are days when I wonder. On those days, I remind myself of the real reasons I teach:
It's in my blood. My mother was my most influential teacher, and she was a 6th grade reading teacher until her death in 1990. She instilled(逐漸灌輸) in me a love of reading and the knowledge that education opens doors.
Teaching is a way to make a difference. If you throw a stone in a pond the ripples go on and on until they reach the shore. You can't have ripples without a "stone." Good teachers throw stones that make a positive difference, and that's what I strive to do.
I genuinely love teenagers.
I want to share with others what I know and what I have learned through the years. Life is full of ups and downs, and if I can help students avoid some potholes on the road of life, I want to do so. If they'll allow me to celebrate their victories with them, I want to do too.
Teaching isn't for everyone, but I know I made the right career choice.
41. Why did the student continue to ask the question about the writer’s being a teacher?
A. Because he thought her answer was unbelievable.
B. Because the writer was insincere.
C. Because the student was naughty.
D. Because the answer was difficult to understand.
42. What do you think of the writer?
A. Stupid.                       B. Honest.                    C. Conservative.                   D. Polite.
43. According to the text, which of the following is NOT true?
A. The writer’s mother has the greatest influence on her.
B. The writer’s answer made the student confused.
C. In the writer’s opinion, some people in the world are unfit to teach.
D. The writer annoyed the student who asked the question.
44. We can infer from the text that _________.
A. the writer was also a good teacher in school
B. the writer often plays with her students beside a pond
C. the writer devotes herself to teaching and her students
D. the writer often accompanies the students on their way home
45. What’s the main idea of the text?
A. A student’s silly question.                                 B. A good teacher who likes students.
C. A confused student.                                          D. The reason why I teach.
