It should be very clear that we live in a most spectacular(壯觀的)time. It’s a time when information is of primary importance. It’s a time when new information technologies are fundamentally transforming the world in every aspect. Among the changes, which have come upon modern society, the ones in education are probably the most obvious and influential. New information technologies are accelerating changes in education, at the same time presenting revolutionary tools with the potential to make education more efficient and more effective than ever.
The application of new information technologies has remarkably promoted the process of education. Online learning is probably the best case in point. As is often the case with “technology”, online learning may appear to be horrible; it can sound like alphabet soup sometimes. Now let’s see whether you can understand all this. You can participate in CBT at a CLC via the convenience of IDL. What does it all mean? Let me translate: GBT—Computer-Based Training; CLC—Computer Learning Center; IDL—Interactive Distance Learning. Sound complicated? Not really. Online learning is much less complicated than it seems. Students can learn at any time, anywhere, at any speed. They can make their own learning schedules and follow their own paths to suit their lifestyles. In my university, every semester there’re several online courses available, which need no class meetings or paper materials. The only thing I have to do is just to get online regularly as I wish, and download necessary learning materials. Then everything I need to know about the course is only a click away.
But online learning is not perfect; it’s like the microwave oven: it does some things better, but it is not a complete replacement for the traditional model. The traditional classroom model for education and learning is hard to leave behind. Because humans are social creatures, there’re times when we need to see each other face-to-face for interactive learning. A social and personal connection often builds effective teams, solves problems, and inspires confidence. So one possible solution is to combine online learning with the old traditional classroom learning , which not only makes the learning process faster and cheaper, but also highlights the interactions between teachers and students.
The bottom line: the Internet is the most important educational tool in the information age and online learning will become a main part of every individual’s learning experience in the future. That’s exactly how we will move knowledge from the ones who have it to the ones who need it faster and cheaper, and that’s how we’re going to survive in the information age.

We are always told that TV is not good for us. If it is true, how come the TV-addicted kids of our young generation nowadays are much smarter than we are? In my family, the only persons who can work the TV remote control well are the children.
Probably TV really educates us. For example, we can learn a very useful medical fact: A man that has been shot always has time to speak a broken sentence when he is dying. “The killer was…” (dies)
But I suppose the biggest things that we learn from TV can be regarded as “Life Skills”. Bad things simply happen on either stormy or dark nights. Emotional breakdowns make people wander in the heavy rain without raincoats or umbrellas. And contrary to the scientists, the crack of lightning and the accompanying flash come on at exactly the same time, wherever the scenes are.
I’ve even got to know useful geographical facts from science-fiction shows: Aliens only speak the language of English no matter which planet they come from.
To make good use of something that we learn from TV can make our security better. Consider these truths. When you are really attacked by 20 bad guys, you needn’t worry about your being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
TV often teaches us a lot of important information as well about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
Be warned, however, if your name card says “henchman” (幫兇) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
小題1: When the writer says “A man that has been shot always has time to speak a broken sentence when he is dying” (Paragraph 2), he shows his________.
A.humorB.sympathyC.deep concernD.medical knowledge
小題2: We can learn from Paragraph 3 that in the real world________.
A.bad things cause people to break down in the rain
B.bad things never happen on dark and stormy nights
C.people with emotional problems like to walk in the rain without umbrellas
D.you can’t hear the crack of lightning and see the accompanying flash exactly at the same time
小題3: On TV what usually happens when a person turns it on?
A.The program shown is always about the importance of TV.
B.The person always turns off the TV when it’s time for news.
C.The news shown is always about someone the person knows.
D.TV always shows news about famous people.
小題4: What’s the main idea of this passage?
A.Life skills can be learned from TV.
B.What happens in TV is quite different from reality.
C.Watching TV makes people more creative.
D.TV plays an important role in society.
小題5: The writer of this passage takes a(n) ________ attitude towards TV plays.
A.positiveB.casualC.negativeD.indifferent

The Segway Human Transporter was invented by Dean Kamen.It is a two-wheeled vehicle designed for a single rider standing upright over its single axle(軸) and navigate using a set of handlebars resembling those on a bicycle.Electrically powered, it could travel over 15 miles on a single charge and reach speeds up to twelve miles per hour.Its speed and direction can be controlled by riders' changing their weights.
A college dropout and self-taught engineer, Kamen already held over 100 patents for his inventions when he developed the one he hoped would revolutionize short-distance travel.While still in college, Kamen started developing the medical devices (設(shè)備) that made his name.Later, he changed focus to the challenges faced by wheelchair users.His robotic wheelchair known as IBOT could climb stairs.This robot ended up paving the way for the Segway.
Before showing his most recent invention, Kamen had kept it a top secret for months.When it turned out to be little more than a motor scooter, many publicly expressed their disappointment.On closer examination, however, even his critics(批評家) had to admit that the vehicle was an engineering achievement.It answered the prayers of anyone who is worn out when walking downtown.Not everyone welcomed the Segway's arrival, though.Some complained it was too expensive, while others said it would further weaken the average American ' s fitness.A Japanese inventor even accused Kamen of stealing the idea for the Segway from him.
Despite the controversy, the U.S.postal service began using Kamen's invention a month after its appearance, and a factory was built with plans to produce about 40,000 Segways every month.The argument is still on whether the Segway will be remembered as the greatest invention since the light bulb, or just another forgettable electronic device.Anyway, trips to the local supermarket will never be the same again.
小題1:Which statement best describes the critics' reaction to the Segway?
A.Nothing but an electrical device.
B.A disappointing engineering mistake.
C.An expensive and disappointing invention.
D.Disappointing, but still a successful device.
小題2:Which is not a feature of the Segway?
A.One person at a time can ride on it.
B.It has two wheels with a single axle.
C.It is powered by electricity and can go up to 12mph.
D.Riders increase the speed by moving the handlebars
小題3:Some people expressed dissatisfaction with the Segway because of its______.
A.high costB.danger to traffic
C.being difficult to useD.contribution to laziness
小題4:Shortly after the Segway appeared, there were _________.

Astronomers have captured(捕獲) the first direct image of a planet being born.
Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.
The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.
Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.
Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.
Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.
Planets can change orbits(軌道) after forming, so it’s difficult to answer such questions by studying older planets.
“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.
Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮強過) them. Kraus and Ireland used two techniques to overcome this problem.
One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.
The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
小題1:The research on younger planets helps scientists _____________.
A.study why planets change orbits after forming
B.understand how planets move around their stars
C.a(chǎn)nswer questions about the age of stars and planets
D.know the relationship between planets and their stars
小題2:Why are young planets like LkCa 15b hard to discover?
A.Their stars are brighter than them..B.They are very far from the earth.
C.They are generally too small.D.They rarely form.
小題3:According to the text, Kraus and Ireland _____________.
A.have been working in the same university
B.observed the planet on a volcano in Hawaii
C.used two new methods in the observation
D.cut holes in the mirrors when observing
小題4:Which of the following would be the best title for the text?
A.Youngest planet seen as it’s forming.
B.Planet 450 light years away discovered.
C.World’s first direct image of a planet taken.
D.New technique helps discover young planets.

In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about a half a dozen generate (引起,導(dǎo)致) the strong, circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling disturbances hundreds--- even thousands--- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds. When conditions are just right, warm, moist air flows in at the bottom of such a disturbance, moves upward through it and comes out at the top. In the process, the moisture in this warm air produces rain, and with it the heat that is converted to energy in the form of strong winds. As the heat increases, the young hurricane begins to swirl in a counter-clockwise (逆時針方向) motion.
The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane’s rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months.
Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea, the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.
小題1:When is an ordinary tropical storm called a hurricane?
A.When it begins in the Atlantic and Caribbean seas.
B.When it hits he coastline.
C.When it is more than 75 mils wide.
D.When its winds reach 75 miles per hour.
小題2:What is the worst thing about hurricane?
A.The destructive effects of water.
B.The heat they release.
C.That they last about nine days on the average.
D.Their strong winds.
小題3:The counter-clockwise swirling of the hurricane is brought about by           .
A.the low-pressure area in the center of the storm
B.the force of waves of water.
C.the trade winds
D.the increasing heat
小題4:Apparently the word “downpour” in the fourth paragraph means           .
A.heavy rainfall
B.dangerous waves
C.the progress of water to the hurricane center
D.the increasing heat

It seems that many college graduates are unsure of what to do with their lives, so they jump back into the college scene by default(違約). But graduate school is costly, time consuming and requires a lot of in-depth study, and also parents will lay down more money and banks will supply more student loans.
However, there are some students who should be pursuing graduate degrees. Teachers, lawyers, doctors, professors and ministers are a few examples of those who will benefit from class work past a bachelor’s degree. Their professions call for additional courses and more specialization and therefore higher education is a must. Still, all students in general should not adopt the idea that graduate school is necessary for individuals who want to make more money. Working hard right after college can lead to promotions in the future. It seems that it does more good to network or internship(實習(xí))with professionals while pursing a bachelor’s degree than it does to complete a master’s and distant oneself from the world of work.
If a student graduates with a four-year degree and immediately enters the work force , he will most likely start an entry-level pay. In a couple of years this employee will gain seniority and experience, therefore increasing their chance for pay rise. He will learn the information at his job-site that he did not learn in school. His bachelor’s degree loan can be immediately chipped away ,and his maturity level can increase as real work related responsibilities set in. But, if the student pursues a master’s degree, he may be able to demand more pay initially when he finally goes job hunting, but years of serious money making as well as work experience will already be lost.
Students should not shy from the workforce just because uncertainty follows graduation. Those who pursue a graduate degree just because they do not want to leave school and because they view the “real world” as scary should think again. Using graduate studies as a hiding place from the full-time job is a waste of time.
小題1:College graduates who go to work can _____ than those who pursue graduate degrees.
A.make more money in the futureB.a(chǎn)cquire more experience
C.get a better jobD.become more responsible
小題2:The underlined words “chipped away” can most possibly be replaced by_______.
A.given outB.set downC.thrown awayD.paid off
小題3:What would be the best title for the passage?
A.College graduates shouldn’t pursue graduate degrees
B.College graduates should think twice
C.How can college graduates make more money?
D.Students use graduate school to avoid reality

It’s common for parents to feel emotional when the moment comes for their child to leave home and go to university. Even parents who don’t speak about the event are likely to feel a sense of sadness because it’s the end of an era where you and your family were at the centre of your child’s world. As a parent you’ll probably continue to support your child in different ways, but the main job of raising your child is over. It’s a huge change for everyone involved.
There are a few things that you can do to make the transition easier. Plan carefully for your child’s departure and think about how you can help. Many parents take their child to university for the first time. If you decide to do that, be ready to feel a real wrench when the time comes to say goodbye. Your child will probably be as nervous as you are about the moment when you finally say goodbye – but that might not show!
Be positive and cheerful about the choice your child has made to continue studying, and plan to leave once you’ve unpacked the car and looked around your child’s new living accommodations. If you can, save your tears for the car – you’ll make things easier on your child and yourself.
The more you’ve invested in being a parent, the more you’ll feel a sense of loss, so the sadness you feel now is a sign that you’ve been a good mom or dad. Remind yourself that parenting is all about raising an independent and confident child who functions well without you. If your child quickly settles and starts enjoying himself, you should congratulate yourself.
It’s also only fair to allow yourself some time to grieve. Don’t expect to pick yourself up and move on straight away. But you may decide to find a hobby or sport to fill your extra time. Perhaps you’ve always wanted to learn a new language, go to yoga classes or take up swimming. You may decide to spend more time with family and close friends, who are likely to be feeling the absence of your child as well.
Agree on the best approach to staying in touch before your child leaves, and stick to your agreement. Try not to panic if your child doesn’t respond immediately – remember, they’re starting a new and busy life.
小題1:The underlined word “wrench” in Paragraph 2 means a feeling of ________.
A.sorrowB.regret C.a(chǎn)ngerD.love
小題2:What does good parenting consist of?
A.Supporting your child in different ways all the time.
B.Congratulating yourself when your child goes to college.
C.Preparing your child to stand on their own feet in the future.
D.Investing as much as possible in the growth of your child.
小題3:What’s NOT advised as the way to recover from your child’s departure?
A.Developing a new hobby or sport
B.Learning a new language.
C.Spending more time with close friends
D.Staying in touch with your child.
小題4:What would be an appropriate title for the whole passage?
A.Staying in Touch with Your Child

What makes a person a scientist?Does he have ways or tools of learning that are different from those of others?The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter(木匠).You will probably agree,too,that knowing how to investigate(調(diào)查),how to discover information,is important to everyone. The scientist,however,goes one step further;he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.?
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different,any changes the scientist observes in a demonstration(實證)must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein,who developed the Theory of Relativity,arrived at this theory through mathematics. The accuracy(正確性)of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(計算)that may test his investigations.
小題1:What makes a scientist according to the passage?
A.The tools he uses.B.His ways of learning.
C.The way he uses his tools.D.The various tools he uses.
小題2:“...knowing how to investigate,how to discover information,is important to everyone.” The writer says this to show_______.
A.the importance of information
B.the difference between scientists and ordinary people
C.the importance of thinking
D.the difference between carpenters and ordinary people
小題3: A sound(合理的) scientific theory should be one that_______.
A.works under one set of conditions at one time and also works under the same conditions at other times
B.doesn’t allow any change even under different conditions
C.leave no room for improvement.
D.can be used for many purposes
小題4:What is the main idea of the passage?
A.Scientists are different from ordinary people.
B.The Theory of Relativity?.
C.Exactness is the core(核心)of science.
D.Exactness and way of using tools are the keys to making of a scientist.

Sigmund Freud was one of the first scientists to make serious research of the mind. The mind is the collection of activities based in the brain that involve how we act, think, feel and reason.
He used long talks with patients and the study of dreams to search for the causes of mental and emotional problems. He also tried hypnosis(催眠術(shù)). He wanted to see whether putting patients into a sleep-like condition would help ease troubled minds. In most cases he found the effects only temporary.
Freud worked hard, although what he did might sound easy. His method involved sitting with his patients and listening to them talk. He had them talk about whatever they were thinking. All ideas, thoughts and anything that entered their mind had to be expressed. There could be no holding back because of fear or guilt.
Freud believed that all the painful memories of childhood lay buried in the unconscious self. This part of the mind he said contains wishes, desires and experiences too frightening to recognize.
He thought that if these memories could somehow be brought into the conscious mind, the patient would again feel the pain. But this time, the person would experience them as an adult. The patient would feel them, be able to examine them and, if successful, finally understand them.
Using this way, Freud reasoned, the pain and emotional pressure of the past would be greatly weakened. They would lose their hold over the person's physical health. Soon the patient would get better.
Many of Freud's theories about how the mind works also had strong sexual connections. These included what he saw as the repressed feelings of sons toward their mothers and daughters toward their fathers.
If nothing else, Freud's ideas were revolutionary. Some people rejected them. Many others came to accept them. But no one disputes his great influence on the science of mental health.
小題1:How many methods did Sigmund Freud use to study the mind?
A.One.B.Two.C.Three.D.Four.
小題2:Sigmund Freud’s research was difficult because ______.
A.he had to work hard and have patients talk freely
B.he had to live with people who had troubled minds
C.he had to listen to unhappy stories of different people
D.he had to give his patients a sense of security
小題3:Sigmund Freud held the idea that the painful memories of childhood ______.
A.could be forgotten forever
B.could have a life-long influence
C.could become wises and desires
D.could be understood unconsciously
小題4:If an adult parent feels the memories of childhood painful, the patient would probably ______.
A.have physical and mental problems
B.be greatly influenced by them
C.have a better understanding of life
D.have a healthier and happier life
