Light travels at a speed which is about a million times faster than the speed of  sound. You can get some idea of this difference by watching the start of a race. If    you stand some distance away from the starter, you can see smoke from his gun      before the sound reaches your ears.
This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light   rays left the moon 1.3 seconds before they reached you. The nearest star is so far  away that the light that you can see from it tonight started to travel towards you    four years ago at a speed of nearly 2 million km. per minute. In some cases, the    light from one of tonight’s stars had started on its journey to you before you were born.
Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We   have to say instead, “The stars look pretty. They were shining four years ago, but    their light has only just reached the earth.”
小題1: Light speed is ______ sound speed
A.a(chǎn)s fast asB.a(chǎn) million times slower than
C.a(chǎn)bout millions of times faster thanD.a(chǎn)bout a million times faster than
小題2:If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that ______.
A.you can hear the sound before you see the smoke
B.the sound does not travel as fast as light
C.the sound will reach you before the man fires
D.sound travels about a million times faster than light
小題3:Sunlight obviously (明顯地) ______ than the light of the moon
A.has to travel a greater distanceB.moves less quickly
C.travels much more quicklyD.is less powerful(有力的)
小題4:The scientific way of saying "The stars are shining tonight" should be ______.
A.the stars have been shining all the time
B.the stars seen tonight will shine four years later
C.the stars were shining long ago but seen tonight
D.the starlight seen today could be seen four years ago

Don’t you think your schoolbag is too heavy to bear? The e-schoolbag will free you from the weight.
It is said that e-schoolbags are going to be brought into use in Chinese middle schools soon. An experiment with several hundred e-schoolbags will begin in seven cities: Beijing, Shanghai, Dalian, Shenzhen, Chongqing, Taiyuan and Shijiazhuang. And the e-schoolbags are going to cover all over China if the experiment proves to be successful. In fact, the e-schoolbag should perhaps be called an e-notebook. It is a small hand-held computer for school students.
Heavy schoolbags have long been a serious problem for school students. The average schoolbag of middle school students weighs up to 5 kilos. But the e-schoolbag will change everything. It is much lighter than a usual schoolbag, weighing under 1 kilo.
Also, it is no bigger than a usual book, but it can still hold all the things for study, such as a textbook, a notebook and exercise book. They could be made into chips that are as small as a stamp. The students can read the text page by page on the screen. They can still take notes using a special electronic pen. If they want to know the meaning or the pronunciation of a new word, or even e-mail their teachers, it’s just a press of a button.
In some foreign countries, it is becoming common. But it is hard to tell when people will receive this new form of study. Some say that e-textbooks can be easily broken, some say that it is not good to students’ eyesight to look at the screen for long.  But only time will tell.
小題1:The e-schoolbag has many functions EXCEPT ________.
A.It can pronounce the words.
B.It can send e-mail.
C.It can be used as a dictionary.
D.It can phone somebody.
小題2:According to the passage, the e-schoolbag ­­­________.
A.is not heavy as before but still large
B.is used as an experiment in Tianjin
C.is made of metal
D.is going to cover China if it proves to be successful
小題3:Which of the following statement is TRUE?
A.All the students in China will be required to use this new schoolbag soon.
B.All the people think highly of e-textbooks.
C.E-notebooks are very convenient to students.
D.We will not make notes because the e-notebook can make all by itself.
小題4:The best title for the passage should be ________.
A.An Experiment In China
B.Please Change Your Schoolbag
C.A New Invention, A New Schoolbag
D.Chips

Joker found one of the biggest diamonds in the world right in his own back yard. He sold the stone to a diamond dealer for over three hundred thousand dollars. In New York, the diamond was resold---this time for almost eight hundred thousand dollars. The true value of a diamond is never known until it has been cut. Once cut successfully, its value can increase a thousand times. It's easy to understand why the owner of Joker's diamond went to the best diamond cutter he knew, Kaplan. The cutter studied the diamond for twelve whole months.
When he felt he was ready to start work, he discovered a flaw (瑕疵) . He had to begin his calculations all over again, or he might have made the stone useless. Six months passed, and Kaplan finally said to the owner, “I am ready to start my work. There will be one excellent diamond that will be comparable one excellent diamond of first-class quality (質(zhì)量)  " Kaplan waited a few more days until he felt he was in the best physical and mental (精神的) condition(條件) possible. He picked up his tools (工具) and held his breath as he made the diamond exactly as he promised.

Mobile phones are an important business tool for farmers in rural areas.But they also put a valuable educational tool in their hands.
The University of Illinois in the United States has a project called SAWBO—Scientific Animations Without Borders.It produces educational videos that can be downloaded to cell phones.The goal is to help people in developing countries improve their lives.
One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops.The process starts with sorting and drying the neem fruits.Then let the fruit dry in the sun for about three or four days, until they become brown.Using a mortar(碾槌) and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside.
The videos use computer animation(動畫).Some of the animated characters are a little funny looking-like a farmer with a long nose.But the subjects are serious, including a health video on preventing cholera(霍亂).Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood.He says, “The information is digested in such a way that in two minutes, we can transmit a complex idea.”
The researchers tested the seven-minute video on seven mobile phones.They wanted to see if people would share the video using Bluetooth wireless technology.With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the internet.As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages." This is just incredible impact," said Francisco Seufferheld.
The team has made a few videos so far.These are available in a total of eighty languages, dialects and accents.Professor Barry Pittendrigh says there are plans for more videos later this year.
小題1:What is the text mainly about?
A.A best-selling mobile phone
B.A valuable educational project for farmers
C.United States support for developing countries
D.A new type of scientist –farmer relationship
小題2:The SAWBO program is introduced in order to ____.
A.raise farmers’ standard of living
B.do some research on mobile phones
C.develop farmers’ practical skills
D.help farmers prevent insect damage to crops
小題3:The biggest advantage of the program is that it______.
A.includes health video on preventing cholera
B.can be passed to farmers using Bluetooth technology
C.can be used to sort and dry the neem fruits
D.is easy for farmers to understand

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict(沖突)between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part,this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ (青少年)complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.
In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrel on unimportant things. Examples include the color of the teen’s hair, the cleanness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong,for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.
小題1:Why does the author compare the parent teen war to a border conflict?
A.Both can continue for generations.
B.Both are about where to draw the line.
C.Neither has any clear winner.
D.Neither can be put to an end.
小題2:What does the underlined part in Paragraph 2 mean?
A.The teens blame their parents for starting the conflict.
B.The teens agree with their parents on the cause of the conflict.
C.The teens accuse their parents of misleading them.
D.The teens tend to have a full understanding of their parents.
小題3:Parents and teens want to be right because they want to__________.  
A.give orders to the otherB.know more than the other
C.gain respect from the otherD.get the other to behave properly
小題4:What will the author most probably discuss in the paragraph that follows?
A.Causes for the parent-teen conflicts
B.Examples of the parent-teen war
C.Solutions for the parent-teen problems
D.Future of the parent-teen relationship

Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education—to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all.
However, many students won’t do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either.
Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules.
In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.
小題1:Open education allows the students to_________________.
A.grow as the educated
B.be responsible for their life
C.discover subjects outside class
D.develop their own interests
小題2:Open education may be a good idea for the students who __________.
A.worry about grades and rules
B.a(chǎn)ren’t used to making choices
C.do well in a traditional classroom
D.enjoy having some rules in class
小題3:Some students will do little in an open classroom because___________.
A.there are too many rules
B.they don’t like activities
C.there are too few rules
D.they worry about the rules
小題4:Which of the following best summarizes the passage?
A.Open education is a really complex idea.
B.Open education is better than traditional education.
C.Traditional teachers don’t believe in open education.
D.The writer thinks open education is practical.

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough,the answer to both these questions is yes. To some extent(程度)our intelligence is given to us at birth,and special education can never make a genius(天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts can be supported in a number of ways.
It is easy to say that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins, they  will very likely be as intelligent as each other. Relations like brothers and sisters,parents and children,usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine that now we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
小題1:By using the example that two people closer in blood relationship are closer in intelligence that writer wants to prove    _    .
A.intelligence can be developed by environment
B.intelligence is given at birth
C.intelligence can be developed by experience
D.education plays an important part in the development of education
小題2:A child who lives in rich and varied surroundings turns out higher in intelligence because ________.
A.his family is rich and therefore can afford to develop his intelligence
B.he can break the limits of intelligence fixed at birth
C.his family is rich and provides him with various healthy food
D.these surroundings are likely to help him reach the limits of their intelligence
小題3:In the second paragraph “if we take two unrelated people at random from the population...” means “if we ____.”
A.choose two persons who are relative
B.take out two different persons
C.choose two persons with different intelligence
D.pick any two persons
小題4:The best title for this passage might be __________.        
A.Birth and EnvironmentB.Intelligence
C.The Answer to a QuestionD.Intelligence and Education
