School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to learn some facts or a formula by heart. It is actually quiet easy to learn a certain fact in history or a formula(公式) in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientist, such as Einstein, Newton and Galileo, didn’t get everything from school. But they were all so successful and invented so many things for men. They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.
小題1:According to the passage, a good teacher should be one who is to_________.
A.help his students to gain a good memory.
B.train his students’ ability to learn
C.teach his students everything he knows
D.have his students studying long hours
小題2:If a student want to learn better, the most important thing for him to do is_______.
A.to learn all the useful facts and formula by heart
B.to do everything as his teacher have said in class
C.to absorb (吸收) as much knowledge from his teacher as possible
D.to think more while he is studying
小題3:The main reason for the success of the great scientists is that________.
A.the teachers who had taught them were all experienced.
B.they used to work and study without a moment’s rest.
C.they had received more schooling than other people
D.they know how to study and worked hard
小題4:What’s the good advice the writer gives us?
A.We can learn better without teachers
B.We should do more asking and thinking while studying
C.We should pay enough attention to classroom
D.Book knowledge is of little use

小題1:B
小題2:D
小題3:D
小題4:B

試題分析:學校教育非常重要,然而學校卻不能教給學生他們所需要的一切,所以老師不僅要教給學生一些事實和公式,更重要的是要教給學生正確的學習方法,也就是要教給他們如何去學習,如何去思考,如何去閱讀。而且作者在文中用愛迪生和牛頓的例子更好的證明了這一點。
小題1:B推理判斷題。根據文章第一段The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. 可知教師的職責就是要教會學生如何去學習,所以B選項正確。
小題2:D推理判斷題。作者在文中講到了愛迪生和牛頓的成功,他們沒有受過多少學校教育,然而他們卻成功了,再根據They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.可以推斷D為正確選項。
小題3:D推理判斷題。在文章第二段作者提到知道如何學習要比單純記憶事實和公式更重要,然后以愛迪生和牛頓為例,從文中They worked hard all their lives, 以及They would ask many questions as they read and they did thousands of experiments.可知他們的成功是因為他們的努力和好的學習方法。所以D選項正確。
小題4:B推理判斷題。根據文章內容可知作者認為懂得如何學習要比單純記憶背誦重要的多,而且通過愛迪生和牛頓的例子闡明了努力和掌握正確學習方法的重要性,由此推斷作者給我們的建議應該是學會思考,故B選項正確。

In all the world's cultures, people sing, play instruments, and celebrate with music. It plays such an important role in our lives that all fields focus on its study, including one looking at the biology of music. Experts are finding that because of the way our brains process music, learning to play an instrument or just listening to music can have a wide range of benefits.
Music education has received a lot of attention. Learning to play an instrument can help children improve math, science, and language skills. One study in Canada tracked children's IQ scores for nine months, discovering that children who studied music had the biggest test score improvements. The secret may lie in the way reading music and playing notes uses several areas of the brain, increasing our ability to learn school subjects. For example, reading notes improves spatial (空間的) reasoning skills, which are helpful in solving math problems like fractions(分數).
Music is also used for medical purposes, such as the treatment of diseases which affect memory. The secret lies in the way the brain processes music. One area near the forehead, the medial prefrontal cortex, connects music with memories stored in two other areas: the amygdale and hippocampus. That's why an old song can remind you of something that happened years ago. For patients suffering from diseases like Alzheimer's, listening to music can help unlock buried memories by strengthening musical pathways to memories.
With the evidence of music's benefits pouring in, it's no wonder some countries make  music study a part of their education systems. People are recognizing that more than just a  form of entertainment, music is also great for the brain.
小題1:Scientists are studying music because _______.
A.music can be used for medical treatments
B.music plays a very important role in our lives
C.our brains can possess music in different ways
D.music education has received a lot of attention
小題2:According to the Canadian study, which children had increased IQ scores?
A.Those who already had high IQs.
B.Those who had always played music.
C.Those who could not play any instrument.
D.Those who studied music for a period of time.
小題3: Which of the following is a kind of disease?
A.Spatial reasoning.B.Alzheimer's.
C.The amygdale and hippocampus.D.The medial prefrontal cortex.
小題4:What can be the best title for the text?
A.Music and healthB.Music and the mind
C.Music and educationD.Music and instruments

For thousands of years, mankind has produced plants and animals to create more desired and useful plants and animals. For example, modern com has been produced to such a large size that it is no longer able to reproduce without man’s assistance. Modern dairy cows produce too much milk and if they are not often emptied of milk, they could leak, burst, become infected, and possibly die. Besides, most dogs raised by people can not survive in the wild even with special training.
Since natural evolution is extremely slow and mankind’s selective production programs only take a few generations to produce a completely new species, natural evolution has already taken a back seat to mankind’s production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths (猛犸象) probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i»t cause most of the destruction during man’s rule of the world.
Currently, scientists are creating new species with desired characteristics in the lab significantly faster than natural evolution creates new species. In a single generation, new species can be created and destroyed by mankind, while natural evolution could take thousands of years to do the same but only accidentally. Scientists are even able to replace defective (有缺陷的) or damaged genes with different genes to attempt to cure genetic defects. This is something that natural evolution could possibly never correct.
Eventually scientists will even be able to improve the quality of people. For example, imagine not only correcting your eyesight with gene treatment, but also ensuring that all of your children do not receive your old genes of poor eyesight too. Scientists will one day be able to improve the memory and intelligence of your children, so that they will do better in school and achieve more in life. Doctors and scientists will be able to customize (訂制) babies before they are born just like picking options at a car store.
小題1:According to the first paragraph,______ .
A. man-made evolution has improved all species
B. man-made evolution has weakened some species
C man-made evolution can make up for all natural losses
D. natural evolution won’t happen without man’s assistance
小題2:What does the underlined part “taken a back seat to” in Paragraph 2 mean?
A. Become powerful assistance to.  
B. Become a huge barrier to.
C Speeded up the process of.   
D. Played a less important role than.
小題3:What does the third paragraph mainly talk about?
A.Why natural evolution happens so slowly.
B.The way scientists adopt to have genetic defects repaired.
C.The advantages of man-made evolution over natural evolution.
D.How scientists make use of man-made evolution to create new species.
小題4:What can we infer from the passage?
A.Near-sighted parents will be able to produce babies with good eyesight in the future.
B.Doctors and scientists will be responsible for mass production of babies in the future.
C.It is natural evolution that is to blame for the destruction of European wolves and mammoths.
D.Children can now have their memory and intelligence improved with the help of gene treatment.

We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans,  killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-­year ­old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute,
has discovered a way to make plastic bags degrade(分解) in as few as 3 months, a finding that won him first prize at the Canada-Wide Science Fair, a $10 000 prize, a $20 000 scholarship, and a chance to revolutionize a major environmental issue.
Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he ground plastic bags into a powder and concocted(調制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” said Daniel Burd.
小題1:Daniel Burd won first prize at the Canada-Wide Science Fair because________.
A.he found a new kind of microorganism
B.he contributed much to environmental protection
C.he found a way to degrade plastics in shorter time
D.he could encourage microbes growth in an easier way
小題2:Daniel Burd exposed one plastic sample to dead bacteria to ________.
A.make the live bacteria work better
B.test how effective his method was
C.know which bacteria worked faster
D.control the temperature in the process
小題3:Maintaining the required temperature takes little energy because ________.
A.plastics can get hot easily
B.microbes can produce heat themselves
C.much carbon dioxide is produced
D.the temperature can be controlled
小題4:Daniel Burd got his idea from ________.
A.his school textbookB.the failure of researchers
C.his everyday workD.the practice of other people

Recently a Beijing father sent in a question at an Internet forum(論壇) asking what “PK” meant. “My family has been watching the ‘Super Girl’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “Super Girl” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students’ compositions using Internet jargons(行話) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge(Chinese pinyin for brother). “PLMM” refers to Piao Liang Mei Mei(beautiful girl). “FB” means Fu Bai(corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female) or a Qing Wa(frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!
小題1:By writing the article, the writer tries to              .
A.explain some Internet language
B.suggest common Internet language
C.laugh at the Beijing father
D.draw our attention to Internet language
小題2:What does the writer think about the term “PK”?
A.Fathers can’t possibly know it.
B.The daughter should understand it.
C.Online game players may know it.
D.“Super Girl” shouldn’t have used it.
小題3:The examples of the Beijing father and the Tianjin teacher are used to show that Internet jargons              .
A.are used not only online
B.can be understood very well
C.are welcomed by all the people
D.cause trouble to our mother tongue
小題4: What would be the best title for the passage?
A.A puzzled fatherB.Do you speak Internet-ish?

You do not need every word to understand the meaning of what you read. In fact, too much emphasis (強調) on separate words both slows your speed and reduces your comprehension.
First, any habit which slows down your silent reading to the speed at which you speak or read aloud, is inefficient. If you point to each word as you read, or move your head, or form the words with your lips, you read poorly. Less obvious habits also hold back reading efficiency (效率). One is "saying" each word silently by moving your tongue or throat; another is "hearing" each word as you read.
These are habits which should have been outgrown long ago. The beginning reader is learning how letters can make words, how written words are pronounced, and how sentences are put together. Your reading purpose is quite different, which is to understand meaning.
It has been supposed that up to 75% of the words in English sentences are not really necessary for expressing the meaning. The secret of silent reading is to find out those key words and phrases which carry the thought, and to pay less attention to words which exist only for grammatical completeness.
An efficient reader can grasp the meaning from a page at least twice as fast as he can read the page aloud. He takes in a whole phrase or thought unit at a time. If he “says" or "hears" words to himself, they are selected ones, said for emphasis.
小題1:This passage is mainly about ______.
A.improving eye movement
B.reading more widely
C.changing poor reading habits
D.reading as fast as you can
小題2:Saying each word to yourself as you read _____.
A.improves comprehension
B.increases reading speed
C.gives too much emphasis
D.reduces reading efficiency
小題3:Your reading purpose should be _____.
A.to understand all the words
B.to make fewer eye movements
C.to understand meaning
D.to understand the grammatical structures
小題4:While reading, efficient readers usually _____.
A.move their eyes quickly
B.take in whole phrases or thought units
C.point at key words
D.read only important points for speed

Let us begin by saying what does not cause our dreams. Our dreams do not come from “another world ”. They are not messages from outside source. They are not a look into the future , either .
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind .If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has effect on you while you are sleeping (feeling of cold, a noise, a discomfort, etc.) and it may also use your past experiences and the wishes and the interests you have now.This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom.
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment.A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton.He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands!
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean.Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem.They believe that dreams are mostly expressions of wishes that do not come true.In other words, dreams are a way of having your wishes carried out.
小題1:From the passage we know that our dreams ___________.
A.are imagination of our daily life
B.are man’s curious look into the future
C.have nothing to do with our feelings
D.are to some degree connected with our feelings
小題2:Older children often dream of examinations probably because ___________.
A.they are interested in exams
B.they are often worried about their studies
C.they hope for a better life
D.they show much interest in their studies
小題3:According to the writer , the explanation of dreams that some scientists made ___________.
A.is considered interesting , but unreasonable
B.gives a good answer to the question why we dream
C.has some value , though not fully convincing
D.has been proved by the findings of their studies
小題4:What is the best title for this passage ?
A.Why People Dream ? B.New Findings about Dreams
C.Dream Makes Hopes D.What Dreams Mean ?

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.
