Michael Fish may soon be replaced as a weather forecaster by 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 behavior of sharks to predict bad weather.
Miss Smith had previously studied the behavior 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.

試題分析：本文為科普類文章，介紹了一位英國(guó)生物系學(xué)生對(duì)于鯊魚來(lái)預(yù)測(cè)暴風(fēng)雨的研究。
小題1:推理判斷題。本題適宜用排除法。由文章內(nèi)容來(lái)看這是一篇科普文，A、D可刪除，由文章的語(yǔ)言來(lái)看，并未出現(xiàn)大量的專業(yè)術(shù)語(yǔ)，可刪除C “a research paper”(科研論文) 選B
小題2:推理判斷題。由第一段和第四段可知，前四段所要表達(dá)的含義為If her studies prove the theory,  scientists may be able to monitor the behavior of Sharks to predict bad weather。(科學(xué)家們可以通過(guò)監(jiān)視鯊魚的行為來(lái)預(yù)測(cè)不好的天氣”。故A 項(xiàng)正確。
小題3:事實(shí)細(xì)節(jié)題。由文章倒數(shù)第三段可知,Miss Smith 在鯊魚身上安裝高科技感應(yīng)器來(lái)記錄pressure(壓力)和temperature(溫度),故選D 項(xiàng),C 項(xiàng)不全面。
小題4:主旨大意題。文章的主旨句為第二段,全文圍繞著鯊魚可能被用來(lái)預(yù)測(cè)天氣的研究展開。因此,B 項(xiàng)正確。
點(diǎn)評(píng)：細(xì)節(jié)推斷題要求學(xué)生根據(jù)語(yǔ)篇關(guān)系，推斷具體細(xì)節(jié)，如時(shí)間、地點(diǎn)、人物關(guān)系、人物身份、事件等。一般可根據(jù)短文提供的信息，或者借助生活常識(shí)進(jìn)行推理判斷。解答此類題，不僅需要我們有一定的社會(huì)基礎(chǔ)知識(shí)，而且還需要對(duì)細(xì)節(jié)以及有關(guān)背景知識(shí)有一個(gè)充分的理解。

Scientists from South Korea are trying to convert（轉(zhuǎn)化）sound waves into electricity. The research could lead to charging a cell phone from a conversation or providing energy to the nation’s electricity system generated（產(chǎn)生）by the noise during rash-hour traffic.
“Just as speakers transform electrical signals into sound, the opposite process —turning sound into a source of electrical power — is possible,” said Young Jun Park and Sang-Woo Kim, the joint authors of a new article in the journal Advanced Materials.
Harvesting energy from phone calls and passing cars is based on materials known as piezoelectrics. When bent, piezoelectric materials turn that mechanical energy into electricity. Lots of materials are piezoelectric: cane sugar, quartz （石英）and even dried bone which could create an electrical charge when stressed. For decades, scientists have pumped electricity into piezoelectric materials for use in environmental sensors, speakers and other devices.
Over the past few years, however, scientists have made dramatic advances in getting electricity out of piezoelectric devices. In an experiment, by using sound waves, which at 100 decibels（分貝）were not quite as loud as a rock concert （a normal conversation is about 60-70 decibels）, the South Korean scientists produced a mild electrical current of about 50 millivolts（毫伏）. The average cell phone requires a few volts to function, several times the power this technology can currently produce.
“But the real question is whether there is enough surrounding noise to act as a power source as for a cell phone,” said McAlpine, a leading scientist. A consumer probably wouldn’t want to attend a rock concert or stand next to a passing train to charge his cell phone. The South Korean scientists agree but they expect to get a higher power output as they continue their work.
小題1:According to the two South Korean scientists, ________.
A．sound waves can travel faster than electricity
B．new materials can send cell phone signals better
C．using cell phones adds to heavy traffic in rush hour
D．electricity and sound can be transformed into each other
小題2:We know from the passage that piezoelectric materials ________.
A．can produce electricity when stressed
B．a(chǎn)re good at changing electricity into sound
C．can reduce the noise of passing cars
D．have been widely used in phones and cars
小題3:It can be inferred from the South Korean scientists’ experiment that ________.
A．it is hard to change sound into electricity under current conditions
B．it is impossible to make use of loud sound
C．the technology has a long way to go to have a practical use
D．the technology can power cell phones easily
小題4:What McAlpine doubts about the technology is ________.
A．the noise pollutionB．the sound resource
C．the cost of piezoelectricsD．the safety of devices

That morning, I stepped into the classroom, ready to share my knowledge and experience with seventy-five students who would be my English Literature class. Having taught in  1 for seventeen years, I had no  2  about my ability to hold their attention and to  3  on them my admiration for the literature of my mother tongue.
I was shocked when the monitor shouted, "  4  !" The entire class rose as I entered the room, and I was somewhat  5  about how to get them to sit down again, but once that awkwardness was over, I quickly  6  my calmness and began what I thought was a fact-packed lecture, sure to gain their respect—perhaps  7  their admiration. I went back to my office with the rosy glow which came from a sense of achievement.
My students  8  diaries. However, as I read them, the rosy glow was gradually  9  by a strong sense of sadness. The first diary said, "Our literature teacher didn’t teach us anything today.  10  her next lecture will be better." Greatly surprised, I read diary after diary, each expressing a  11  theme. "Didn’t I teach them anything? I described the entire philosophical framework of Western thought and laid the historical  12  for all the works we’ll study in class," I complained." How _13  they say I didn’t teach them anything?"
It was a long term, and it  14  became clear that my ideas about education were not the same as_15 of my students. I thought a teacher’s job was to raise   16  questions and provide enough background so that students could  17 their own conclusions. My students thought a teacher’s job was to provide _18_ information as directly and clearly as possible. What a difference!

Some people have very good memory（記憶力） and they can easily remember quite long texts. There are other people who can only remember things when they have said them again and again. The famous English writer Charles Dickens said that he could walk down any long street in London and then tell you the name of every shop he had passed. Many great men of the world have a wonderful memory.
A good memory is greatly helpful in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like the boys and girls who live abroad(國(guó)外) with their parents, seem to learn two languages almost as easily as one. In school it is not so easy to learn a second language because the students have so little time for it, and they are very busy with other subjects too.
A man’s mind is like a camera, but it takes photos not only of what we see but also of what we feel, hear, smell and taste. When we take a real photo with a camera, Some people have very good memory（記憶力） and they can easily remember quite long texts.In the same way, there is much work to be done before we can keep a picture forever(永遠(yuǎn)) in our minds.
Memory is a diary, and we all carry it about us. We keep things we have experienced (經(jīng)歷)in this diary.
小題1:Which of the following is true?
A．Charles Dickens had a good memory because he was a famous writer.
B．People without a good memory cannot be great men of the world.
C．People became great because they have a good memory.
D．Many people may never become great though they have a good memory.
小題2:To learn a language well, one must ________.
A．live abroadB．write it every day
C．often hear itD．go to school
小題3:The writer thinks a camera in one’s mind can take photos of ______.
A．what we see
B．what we feel and hear
C．what we smell and taste
D．what we see, feel, hear, smell and taste
小題4:If you have a good memory, ________.
A．you can learn a second language easily
B．you can remember things for ever easily
C．you can learn your own language easily
D．you can remember things better
小題5:Which of the following is true?
A．We all keep a diary in our mind.
B．One has to do a lot of work before he can keep a picture in his mind forever.
C．A person with a good memory can remember things forever.

Will life in the future be better, worse or the same as now? Futurologists（未來(lái)學(xué)家）predict that life will probably be very different in 2050.
First of all, it seems that TV channels will have disappeared by 2050. A computer will send the program directly to the television. On TV screen appear holograms（全息圖）, which are pictures with certain height, width and depth. We will be able to see, smell and touch the things that we see on television.
Water has become one of our most serious problems. Agriculture is changing and people are growing more fruit and vegetables to export. Demand for water will increase ten times in 2050. Some futurologists predict that water will be the cause of war if we don’t act now.
In transport, cars will run on new fuels and go very fast. A car will have computers to control its speed and there won’t be any accidents. On the other hand, space planes will take people around the earth in about three hours. People will fly from Los Angeles to Tokyo by space plane in just half an hour.
In the field of technology, robots will have replaced people in factories. By 2050, we will see robots everywhere. They do not ask for pay rises or go on strike, and they work 24 hours a day. 
Medicine technology will have conquered many diseases by 2050; we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals and will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. If you want all this to come true, you should study science and technology hard.
小題1:What is the main difference between today’s and 2050’s TV?
A．We can use a computer to turn off the TV set.
B．We can talk with the characters appearing on TV.
C．We can choose whatever we like to see on TV.
D．We can touch the things we see on TV.
小題2:What isn’t mentioned about the future in 2050 in the passage?
A．Technology.B．Medicine.C．Movies.D．Agriculture.
小題3:What will be more likely to cause the war in the future?
A．The lack of water. B．The less farmland.
C．The shortage of robots.D．The more space planes.
小題4:From the passage we can infer that by 2050 ____.
A．people will spend less time in studying
B．more and more people needn’t go to school
C．people will have more time to relax or rest
D．no patients will be found in the world

When we read books we seem to enter a new world. This new world can be similar to the one we are living in, or it can be very __50__. Some stories are told as if they were true. Real people who live in a __51__ world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not __52__. They are characters and creatures that are very different from us and do things that would be impossible for us.
But there is more to books and writing than this. If we think about it, even realistic writing is only __53__. How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter, we do seem to learn something about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than __54__. Reading, like writing, is an action. It is a way of thinking. When we read or write something, we do much more than simple look at words on a page. We use our __55__, which is real, and our imagination, which is real in a different way, to make the words come to life in our minds.
Both realism and fantasy (幻想) use the imagination and the “magic” of reading and writing to make us think. When we read something realistic, we have to __56__ that the people we are reading about are just like us, even though we __57__ that we are real and they are not. It sounds __58__, but it works. When we read, we fill in missing information and __59__ the causes and effects of what a character does. We help the writer by __60__ that what we read is like real life. __61__, we are writing the book, too.
Most of us probably don’t think about what is going on in our __62__ when we are reading. We pick up a book and lose ourselves in a good story, eager to find out what will __63__ next. Knowing how we feel when we read can help us become better __64__, and it will help us discover more about the real magic of books.

科目：高中英語(yǔ) 來(lái)源：不詳 題型：單選題

It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?
Ocean water is full of salt— and salt water can hold up more weigh than fresh water. See for yourself!
You Will Need:
● 3 cups of warm water
● Measuring cup (量杯)
● Wide-mouthed jar
● Salt
● Spoon
● Raw (生的)potato
You Will Do:
1. Pour 1.5 cups of warm water into the jar.
2. Add 1/3 cup of salt.
3. Stir(攪拌) until the salt is completely dissolved.
4. Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquid will not mix together.
5. Gently place the potato into the jar. Do not drop it.
What Will Happen:
The potato will sink— but only halfway!
Why?
Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.
The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down.
小題1:In the experiment, what should you do right after you pour the water over the spoon?
A．Add the salt to the water.B．Stir the salt into the water.
C．Place the potato in the jar.D．Pour warm water into thejar.
小題2:In Step 4 of the experiment, why do you pour the water over the spoon “slowly”?
A．It is easier to see what you are doing.
B．It pushes the fresh water to the bottom.
C．It will keep the water from coming out.
D．It will keep the liquids from mixing together.
小題3:In which step of the experiment do you add the salt?
A．Step 1B．Step 2C．Step 3D．Step 4
小題4:What does the underlined word “gently” mean?
A．CarefullyB．QuicklyC．SecretlyD．Silently
