Did you know that the position you choose to sleep in says something about what kind of person you are?
A study of 1,000British people has been done by Chris,a British professor and director of the Sleep Assessment and Advisory Service in the UK.It looked at the six most common sleeping positions and which personalities tend to match them.Have a look.
1. Fetus (胎兒) position – This is the most common sleeping position. About 41 percent of the participants said they sleep in this position. These sleepers may appear to be strong but they are usually sensitive (敏感的) and shy. The more they curl (蜷縮) up, the more worried they are.
2. Log position (樹干睡姿) – This is the second most common position. People who sleep like a log are usually stubborn.
3. Yearner position (向往型睡姿) – This position says that you are open-minded and eager (急切的) to face challenges.
4. Soldier position – These sleepers lie on their backs with their arms down and close to the body. They are usually reserved and quiet.
5. Freefall position – People who sleep in this position are outgoing (外向的) but feel a lack of control in their lives. This is the least comfortable position.
6. Starfish position – People who sleep like this are good listeners, helpful, and uncomfortable being the center of attention.
【小題1】What is the main idea of this passage?

A.Sleeping position decides personality.
B.Sleeping position reflects personality.
C.What the six different sleeping positions are like.

Electrical devices(儀器)could soon use power made by human energy. Scientists say
they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine
that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.
The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.
【小題1】The second paragraph mainly talks about     .

A.who developed the device
B.how the device works
C.several possible uses for the devices
D.how much electricity the device can produce
【小題2】What is the disadvantage of the experimental version of the device?
A.It is too heavy for the walker to bear.
B.It is too complex for people to use.
C.It is too expensive for most people to afford.
D.It will slow down one’s walking speed.
【小題3】Compared with the device designed by Larry Rome, this new device     .
A.produces power without adding more loads to the walker
B.can produce more power in a much shorter time
C.needs to be equipped with a battery
D.can help the walker wa1k faster
【小題4】From the passage, we can learn that the electrical device can     .
A.help housewives operate the washing machine
B.make it much easier for us to go online
C.produce more electricity than that invented by Larry Rome
D.be applied in medicine to operate heart pacemakers
【小題5】What would be the best title for the passage?
A.First device powered by walking wi1l soon be on the market
B.Advanced technology brings in a new way to operate heart pacemakers
C.Device gives new meaning to the idea of power walking
D.Human energy will become a main source of electricity

A successful scientist is generally a good observer.  He makes full 36  of the facts he observes.  He doesn’t accept ideas which are not  37   on obvious facts,  and therefore refuses to accept authority as the only   38   for truth.  He always  39    ideas carefully and makes experiments to prove them.
The rise of    40    science may perhaps be considered to    41   as far back as the    42    of Roger Bacon,  the wonderful philosopher of Oxford,  who live    43    the years 1214 and 1292.  He was probably the first in the Middle    44    to suggest that we must learn science    45    observing and experimenting on the things around us,  and he himself    46   many important discoveries.
Galileo,  however,  who lived more than 300 years later (1564-1642),  was the greatest of several great men,     47    in Italy,  France,  Germany,  or England,  began by    48    to show how many important    49    could be discovered by observation.  Before Galileo,  learned men believed that large bodies fell more    50    towards the earth than small ones,     51    Aristotle said so.  But Galileo,  going to the    52     of the leaning Tower of Pisa,  let fall two  53    stones and proved Aristotle was wrong.  It was Galileo’s    54    of going direct to Nature,  and proving our    55    and theories by experiment,  that has led to all the discoveries of modern science.

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 _____.

Millions of years ago dinosaurs (恐龍) lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to cat. This must be one reason why dinosaurs died out.
We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don’t know about yet. Scientists are trying to make more discoveries about dinosaurs.
Dinosaurs were of many sizes and shapes (形狀).  Some were as small as chickens, while some were about 90 feet long.
There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal’s footprints (足跡) that fight did take place.
【小題1】According to the passage, dinosaurs did exist only ______on the earth.

A.for millions of years
B.millions of years ago
C.more than 100 millions years ago
D.when it was warm and wet somewhere
【小題2】 One reason why dinosaurs died out is that______.
A.there were too many dinosaurs
B.parts of the earth became cold and dry
C.the dead forests there could not supply them with enough food
D.they couldn’t find enough to eat
【小題3】. One more reason may be that ______.
A.new kinds of animals came on the earth
B.some fast and strong animals with big brains could kill them
C.some dinosaurs were as small as chickens
D.some big dinosaurs died in the fights

Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步機). Sometimes they wore running shoes. Other times they ran barefoot (赤腳).
Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of The American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.
【小題1】What’s the main idea of the passage?

A.Walking in high heels could cause less serious effects than running barefoot.
B.Two new discoveries encourage people to run in high heels.
C.Running in shoes is partly good to runners.
D.Two new studies prove running without shoes is beneficial to runners in most cases.
【小題2】Which part of our body could be injured if we run in running shoes?
A.Toes. B.Hips. C.Feet. D.Legs.
【小題3】What can we learn from the passage?
A.The way that we run by landing on the front or middle of our foot could avoid damaging our heel.
B.We should start running barefoot in no time.
C.Running in modern running shoes could cause more serious effects than running in high heels.
D.We won’t be injured if we run barefoot.
【小題4】What is the writer’s attitude towards the use of the modern running shoes?
A.Persuasive. B.Negative. C.Objective. D.Supportive
【小題5】In which section of the newspaper can you most probably read the article?

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving (鋪砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages (短缺). Drier climates are of course more likely to have droughts (干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗機) only when it is full. Help your parents fix any leaks (裂縫) in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?

A.Using river water. B.Throwing batteries away.
C.Paving parking lots. D.Throwing rubbish into lakes.
【小題2】What can be inferred from the text?
A.All water shortages are due to human behavior.
B.It takes a lot of effort to meet our water needs.
C.There is much we can do to reduce family size.
D.The average family in America makes proper use of water.
【小題3】The last paragraph is intended to ______.
A.show us how to fix leaks at home
B.tell us how to run a dishwasher
C.prove what drinking glass is best for us
D.suggest what we do to save water at home
【小題4】The text is mainly about ______.
A.why paving roads reduces our water
B.how much we depend on water to live
C.why droughts occur more in dry climates
D.how human activity affects our water supply

While learning the science lessons, I used to get a doubt--why ear, nose, tongue and eyes should be called as special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connectivity. Interestingly, our hearing is less sharp after we eat a heavy food. Isn’t it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a meal, but the hearing pitch(強度)does change after a heavy meal.
We usually give credit of the taste to our tongue, but do you know that unless saliva(唾液)dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds(味蕾)present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something.
Women are much better smellers than men. They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample. We all can store almost 50,000 different smells, which are strongly tied to the memories.
Pupils(瞳孔)do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make their vision less clear.
Each and every one of us has a particular or individualistic or characteristic smell, which is unique to us, except the twins. This smell is very subtle yet can be sensed even by a newborn. It may be due to this smell that the newborn recognizes the presence of his parents around.
【小題1】What may happen after you have had a rich lunch?

A.Your eyes become weak and can not see well.
B.You may feel energetic and fresh.
C.Your hearing pitch may be decreased.
D.Your tongue may lose the function of taste.
【小題2】. What does the author mean by the underlined sentence in paragraph 2?
A.Our tongues can’t be dried while eating something.
B.If your tongue is dried without any saliva on it, it will not work.
C.A tissue paper is the only thing that can be used to dry our tongues.
D.If your tongue is dried with a tissue paper, it may work as well as before.
【小題3】What makes each person different from anyone else except twins according to the passage?
A.The number of sensory organs.
B.The functions of sensory organs.
C.The particular smell of a person.
D.The style of one’s behavior.
【小題4】Which of the following may be the best title of this passage?
A.The Sensitivity of Sensory Organs
B.The Functions and Connections of Sensory Organs
C.A Newborn’s Sensory Organs
D.Different Senses Between Men and Woman

Bad behavior is something that most people don’t want to tolerate. However, we have had to tolerate it more and more with each passing year. There seems to be no concern for other people’s feelings; nor do we seem to care about other people’s property. We live in an age where saying what is on our minds has priority over any harm that it might do.
There are ways to deal with bad behavior in modern times, though. Too many of us let bad behavior go because we don’t want to rock the boat. This is the time that you should rock the boat and rock it hard. Let people know that you expect it to change. That is the key to dealing with bad behavior. If it continues, take the proper action for the situation you are in. If you have developed the habit of bad behavior, take a hard look at it and then change it. You can’t expect others to behave well if you aren’t willing to look at your own bad behavior and change it.
If you don’t have control over anything in a situation, just walk away from it and move on to something that you do have control over. You needn’t feel ashamed of that. Besides, you must stand firm in what you believe. You can’t control what other people do, but you can control what you do about it. You can’t go wrong if you stand firm in what you believe. Understanding your responsibility is also important. Don’t try to take on the responsibility for other people’s behavior. Take care of what you have to and do it in the way you know it should be done. The rest will take care of itself.
Bad behavior is on the rise with more and more people behaving badly without having to pay any consequences. Worry about how you behave rather than how others behave. Pretty soon, it just may catch on.
【小題1】It can be inferred from Paragraph 1 that _____________.

A.bad behavior is common today
B.bad behavior is sure to hurt people deeply
C.people behave badly because of carelessness
D.people are more understanding than before
【小題2】When dealing with people’s bad behavior, you are advised to ____________.
A.fight it bravely whenever it happens
B.ignore it if it is beyond your control
C.let it go to avoid trouble
D.make people feel ashamed of their bad behavior
【小題3】Why do many people behave badly according to the passage?
A.Because bad behavior is often ignored.
B.Because people are often influenced by others.
C.Because people aren’t punished for their bad behavior.
D.Because people haven’t realized its consequences.

I began to grow up that winter night when my parents and I were returning from my aunt's house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see-—the strange and magical places I had known only from books and pictures. The country I was leaving never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to "the hard times."
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: almost all common troubles eventually go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.
【小題1】How did the author get to know America?

A.From her relatives. B.From her mother.
C.From books and pictures. D.From radio programs.
【小題2】Upon leaving for America the author felt_______.
A.confused B.excited
C.worried D.amazed
【小題3】For the first two years in New York, the author _________.
A.often lost her way
B.did not think about her future
C.studied in three different schools
D.got on well with her stepfather
【小題4】What can we learn about the author from Paragraph 4?
A. She worked as a translator.
B. She attended a lot of job interviews
C. She paid telephone bills for her family
D She helped her family with her English.
