     Are you happy? Do you remember a time when you were happy? Are you seeking happiness today?
     Many have sought a variety of sources for their feeling of happiness.Some have put their heart and
efforts into their work.Too many turned to drugs and alcohol.Meanwhile, untold numbers have looked for
it in the possession of expensive cars, exotic (異國(guó)的) vacation homes and other popular "toys". Most of
their efforts have a root in one common fact: people are looking for a lasting source of happiness.
     Unfortunately, I believe that happiness escapes from many people because they misunderstand the
journey of finding it.I have heard many people say that, "I'll be happy when I get my new promotion."
or "I'll be happy when I lose that extra 20 pounds." It is dangerous because it accepts that happiness is a
"response" to having, being or doing something.
     In life, we all experience stimulus (激勵(lì)) and response.Today, some people think that an expensive
car is a stimulus.Happiness is a response.A great paying job is a stimulus.Happiness is a response.This
belief leaves us thinking and feeling, "I'll be happy when..."
     It has been my finding that actually the opposite is true.I believe that happiness is a stimulus and
response is what life brings to those who are truly happy.When we are happy, we tend to have more
success in our work.When we are happy, we more naturally take better care of our bodies and enjoy
good health.Happiness is not a response but a stimulus.
     Happiness is a conscious choice we make in daily life.For unknown reasons to me, many choose to
be upset and angry most of the time.Happiness is not something that happens to us after we get something we want-we usually get things we want after we choose to be happy.

1. From the second paragraph, we know to many people ________.

A. they are not happy when they work hard  
B. they are not happy when they drink or take drugs
C. they are happy when they possess their own expensive cars
D. they all desire exotic vacation homes

2. Generally speaking, most people feel happy because ________.

A. they think happiness is rooted in their deep hearts    
B. they get what they want to have
C. they get a great paying job                      
D. they get an expensive car

3. In the author's opinion, which of the following is the most important if you want to be happy?

A. Losing weight.      
B. An expensive car.      
C. Success in work.    
D. Feeling happy.

4. Which of the following is TRUE according to the author?

A. If you want to get what you want, you first choose to be happy.
B. We should try to get more and then we'll be happy.
C. Most people today are happy.
D. Work is a necessary part in our daily life.

5. From the viewpoint of the author, happiness is ________.

A. based on our needs          
B. unconditional      
C. out of reach        
D. limited

     Are some people born clever, and others born stupid? Or is intelligence developed by our
environment and our experience? Strangely enough, the answer to these questions is yes. To
some extent our intelligence is given to us at birth, and no amount of education can make a genius
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 person's intelligence are fixed at birth, 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 show 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 intelligence. Thus if we take
two unrelated people at random from population, it is likely that their degree 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 now that 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 degree of intelligence.

1. The writer is in favor of the view that man's intelligence is given to him________.

A. at birth                            
B. through education
C. both at birth and through education      
D. neither at birth nor through education

2. If a child is born with low intelligence, he can_________.

A. become a genius
B. still become a genius if he should be given special education
C. not reach his intelligence in his life.
D. reach his intelligence limits in rich surroundings

3. The example of the twins going to a university and to a factory separately shows_________.

A. the importance of their intelligence    
B. the role of environment on intelligence
C. the importance of their positions      
D. the part that birth plays

4. The best title of the passage can be _________.

A. Surroundings    
B. Effect of education
C. Dependence on Environment    
D. Intelligence

     Are you ready to experience life as it may be in the future?Here are some interesting points to learn
about the future.
     Artificial intelligence:Many years down the road humans  might not even be recognizable because
artificial intelligence  (also known as AI) will have combined with our natural  states.Scientists are learning more about the human brain every day, and they are working toward making smart robots we can use to
help us.Some people say that nanobots-supertiny robots-may help us in invisible (看不見(jiàn)的) ways in the
future.They say they will be everywhere, outnumbering humans many times over!
      Nanotechnology:This is the ability to make tools and  helpful robots that are a billion times smaller
than we can see.Scientists have already made many nanosized tools that they can use.When this science
is improved and becomes more common and affordable, it will change everything.
      Braintocomputer communication:Nanocomputers will probably be linked to your thoughts, voice and
emotions, and be able to react to your needs.In the future people will rely on wireless technology and
everyone and everything  will be linked.Your brain will be able to receive information  from computers
to fill your head with knowledge or teach you new things.When you want to learn a new skateboarding
trick or dance move, nanocomputers will send the information to your brain and allow your body to use
the tips and apply them-no studying involved!
      Virtual reality:You already love virtualreality games-they make imaginary worlds in which you can
play. But what if it allows you to have a cool new school?Virtual worlds are being created so
computergenerated environments will allow you to learn school lessons with your teacher and your
friends seemingly present without actually being there.Technology will give you a 3D image and link it to
your brain in a way that makes you actually feel as if you were there.

1. The passage mainly introduces________.

A. the use of robots in the future    
B. the importance of science and technology
C. some technology in the future    
D. some ways to improve communication

2. What can we conclude from the second paragraph?

A. The number of robots is greater than the number of humans.
B. AI will bring about great changes to people's lives.
C. Nanobots will take the place of humans in some years.
D. Scientists won't stop learning about the human brain until AI is widely used.

3. The fourth paragraph introduces a new way of________.

A. delivering and getting information    
B. school education
C. exercising                       
D. entertaining

4. We can most probably read this passage in________.

A. a government report

閱讀理解
      Are you preparing for a big test? If so, you may want to play some basketball in between hitting the
books. Doctors are starting to find more and more information that suggests a connection between
exercise and brain development. Judy Cameron, a scientist at Oregon Health and Oregon Health and
Science University, studies brain development. According to her research, it seems that exercise can
make blood vessels(管), including those in the brain, stronger and more fully developed. Dr. Cameron
claims this allows people who exercise to concentrate better. As she says, "While we already know that
exercise is good for the heart, exercise can really cause physical changes in the brain."
     The effects of exercise on brain development can even be seen in babies. Babies who do activities
that require a lot of movement and physical activity show greater brain development than babies who
are less physically active. With babies, even a little movement can show big results. Margaret Barnes,
a pediatrician(兒科醫(yī)生), believes in the importance of exercise. She thinks that many learning
disabilities that children have in elementary school or high school can be traced back to a lack of
movement as babies. "Babies need movement that stimulates their five senses. They need to establish a
connection between motion and memory. In this way, as they get older, children will begin to associate
physical activity with higher learning," says Margaret.
     Older people can beef up their brains as well. Scientists from 11 universities studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase
of up to 40 percent after exercising just three hours a week. The exercise does not have to be very
difficult, but it does have to increase the heart rate. Also, just like the motion for infants (嬰兒), exercise
for older people should involve some complexity. Learning some new skills or motions, such as with
yoga or tai-chi, helps to open up memory paths in the brain that may not have been used for a long time.
     For most people, any type of physical activity that increases the heart rate is helpful. The main goal is
to increase the brain's flow of blood. And your brain can benefit from as little as three hours of exercise
a week.
1. What is the best title of this passage?
A. How to exercise                        
B. How exercise helps the brain
C. How to get good scores on a test            
D. How the brain can change
2. According to the reading, what is the connection between exercise and brain development?
A. Exercise makes us stupid.                
B. The brain needs special mental exercise.
C. The more exercise, the bigger the brain.      
D. Physical exercise helps us think better.
3. The mini amount of exercise required to gain any benefit is ________.

A. three hours per week                    
B. 40 hours per week
C. three hours per day                      
D. 40 hours per month

4. Why does the author think that yoga is fit for seniors?
A. It is easy to learn.                      
B. It can be done in groups.
C. It does not increase the heart rate.          
D. It includes learning new motions.
