Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland（瑞士）and China, built by the government（政府）to help some of the people live during a great war. 
But will people change if they live under the ground for a long time？For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals（化學制劑）in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone？
小題1:People will live under the ground because _________． 
A．it’s neither hot nor cold there
B．they’ll be afraid of the war
C．there’ll be less space on the ground
D．they’ll make their life comfortable
小題2:Some countries try to build some places under the ground so that people will be able to live there _____．
A．when summer comes
B．when a war breaks out
C．because they think it’ll be safer for them
D．when they’re fed up with the life on the land
小題3:_________, so people who will live there won’t go blind． 
A．There’ll be enough light under the ground
B．It’ll be easy to go upstairs
C．Glasses will be sold under the ground
D．Medicine will be supplied for free
小題4:People will lose some senses under the ground because _______．
A．the world are polluted
B．it’s dark there
C．the air is dirty and there are a lot of chemicals in their food
D．they can’t grow their own food in the sun

小題1:C 
小題2:B
小題3:A

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．

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．angerD．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
B．Preparing to Say Goodbye to Your Child
C．Dealing with Your Child Leaving Home for University

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.

What will people die of 100 years from now？ If you think that is not a simple question， you have not been paying attention to the revolution that is taking place in bio­technology(生物技術). With the help of new medicine， the human body will last a very long time. Death will come mainly from accidents， murder and war. Today's leading killers， such as heart disease， cancer， and aging itself， will become distant memories.
In discussion of technological changes， the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live？ Human brains were known to decide the final death. Cells are the basic units of all living things， and until recently， scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells， such as those of brain cells， would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100， medicine will have advanced to the point at which every 10 years or so， people will be able to take medicine to repair their organs. The medicine， made up of the basic building materials of life， will build new brain cells， heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence， but many technical problems still must be cleared up on the way to this wonderful future. 
小題1:According to the passage， human death is now mainly caused by____ 　　
A．diseases and agingB．accidents and war
C．accidents and agingD．heart disease and war
小題2:Humans may live longer in the future because ____　　
A．heart disease will be far away from us
B．human brains can decide the final death
C．the basic materials of cells will last forever
D．human organs can be repaired by new medicine
小題3:We can learn from the passage that ____
A．human life will not last more than 120 years in the future
B．humans have to take medicine to build new skin cells now
C．much needs to be done before humans can have a longer life
D．we have already solved the technical problems in building new cells

Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people at your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles (粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2025, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.
So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?

Scientists know of more than 1,000 volcanoes on the surface of Venus, Earth’s “sister” planet. A big question has been: Are they still active? The scientists say yes.
Their evidence for recent volcanic activity on Venus comes from a lava(熔巖) flow in the planet’s northern hemisphere. The flow is hotter than the rocks around, which means the lava might still be cooling off. “The flow we studied seems to be very young---it is still warm inside,” Nataliya Bondarenko said.
Venus is a difficult planet to study from Earth because it is surrounded by thick clouds. Telescopes on Earth can’t see through these clouds, so the best information about Venus comes from spacecraft orbiting it.
Bondarenko and her colleagues studied the lava flow using data from NASA’s Magellan mission. That spacecraft spent four years in orbit around Venus and used radar to make a map of 98 percent of the planet’s surface. On October 11th, 1994, the mission ended, and the spacecraft plunged (跌落) through Venus’ heavy cloud cover and crashed onto the planet below.
While in orbit, the Magellan craft sent microwaves, which can go through Venus’ clouds, to the surface. Microwaves are invisible and can be as long as three feet. These waves are a kind of energy, like light. And like light, they bounce off surfaces. The way the waves bounced off the Venus’ surface and back to the craft supplied information that the scientists used to estimate the temperature of various parts of the planet’s surface. Bondarenko’s team found that the lava flow was hotter than its surroundings---which may mean the lava flow is in the process of cooling.
The scientists say the lava flow can’t be very old because if it were, it would have cooled off enough that Magellan wouldn’t have noticed the difference in microwaves. She adds that the flow appears in a 1978 view of the surface that a craft called the Pioneer Venus Orbiter captured.
小題1:What happened to Magellan in the end?
A．It was floating in space forever.
B．It flew into heavy clouds.
C．It returned to the Earth.
D．It fell onto Venus.
小題2:How could Bondarenko judge the temperature of the Venus?
A．By looking at it with a powerful telescope.
B．By measuring the thickness of clouds over Venus.
C．By calculating the microwave bouncing off Venus’s surface.
D．By orbiting Venus for 4 years in a spacecraft.
小題3:The best title for the passage may be “______ ”.
A．Warm lava on Venus
B．More volcanic eruptions on Venus
C．Venus is just like a big active volcano
D．Lava flows are first found on Venus

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). 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

Our environment isn’t as green and beautiful as it should be. There are steel monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the Earth.
You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what a little we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “ accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.
At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps（水龍頭）are not leaky（泄露的），which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It’s not only energy-saving, but also cuts down electricity costs.
Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.
Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.
With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.
小題1:The underlined word “scrimping” in the third paragraph can be replaced by _____.
A．savingB．cleaningC．cookingD．drinking
小題2:From the fifth paragraph, we can know that ________.
A．protecting the environment begins with small chores
B．protecting the environment should start from childhood.
C．wonderful life comes from environmental protection
D．protecting the environment benefits the country and the people
小題3:Which of the following isn’t true?
A．The more people do their part, the greener the environment will be.
B．Selling what you don’t want any more is a kind of recycling.
C．To protect the environment may help you save some money.
D．Your bad habits for the environment are a valuable contribution.
小題4:Which of the following can be the best title for this passage?
A．The Use of Garbage Dustbin
B．How to Save Water and Electricity
C．How to Save the Environment
D．Our Current Environmental Problems
