    We often hear people say, "I have a good memory for things like that" or "I can remember
names". But do you know memory is the single most important thing and it has played a very
important part?
    For early men, there were dangerous all around them-bad weather, wild animals. The keys
to keep on living lay in man's ability to remember these dangers and the ways he had dealt with
them in the past. In order for memories to be stored, the human brain became more complex.
And as man learned how to deal with them, he became civilized (文明).Surprisingly, scientists
today understand little about memory and how it works. They havenot yet found a way to open
up the brain and observe its function without destroying it. Perhaps there are two types of
memory: short-term and long-term. Short-term refers to those facts that stay with us for a few
seconds to a few hours. For instance, when you stay at a hotel, you remember the room number
and forget as soon as you leave. Long-term memory, on the other hand, means you remember
things for a long period of time. If you spend your honeymoon in a particular hotel, it's likely that
you'll remember your stay quite clearly.
    Scientists also believe that a short-term memory can become a long-term memory through
consolidation (巩固). A lot of chemical and physical changes take place in the part of the brain.
Although the human brain weighs three pounds, it contains 30 billion nerve cells (神经细胞) acting
like a computer. When those changes strengthen the links (联系) in certain nerve cells, a though
becomes a part of the long-term memory.
1. According to the author, without the development of man's memory there would be _____.
[     ]
A. no modern world
B. no recorded history
C. no animals
D. no dangers
2. Scientists' knowledge about the function of brain is _____.
[     ]
A. interesting
B. not enough
C. great
D. encouraging
3. Short-term memory can change into long-term memory on condition that _____.
[     ]
A. memory is good
B. it acts like a computer
C. people do more exercise
D. the links in nerve cells are strengthened by certain changes
4. So far the great discovery scientists have made about the function of brain is _____.
[     ]
A. the weight of brain
B. two types of memory
C. 30 billion nerve cells
D. chemical and physical changes
1-4: ABDD

     We all know that money can't make us happy, but many times we act as if we'd be
happier with a bit more money. We are conditioned to want to be richer; we are trained
to want the latest style that television tells us; we want to earn more money because then
we'll have a good life.
     But none of that will make us happier. And the sad thing is that it can take us decades
of pursuing (追求) wealth and expensive things before we realize that. So what will bring
us happiness? Luckily, there are three things that don't cost anything. Here they are:
     Good relationships. We have a human need to be close with other human beings. Having
good, supportive friendships, a strong marriage or loving relationships with our family members
will make us much more likely to be happy. Therefore, take time, today, to stay with your
loved ones, to tell them what they mean to you, to listen to them, and to develop your r
elationships with them.
     Positive thinking. Optimism(乐观) is one of the best indicators of people who lead a
happy life. Happy people feel empowered, in control of their lives. So why not make
positive thinking a habit? In fact, this should be one of the first habits you develop.
     Flow. This is a popular concept on the Internet these days 一 the state we enter when
we are completely focused on the work or task. Having work and leisure(休闲)that gets
you in this state of flow will almost undoubtedly lead to happiness. People find the greatest
enjoyment not when they're passively mindless, but when they're absorbed in a mindful
challenge.
     If you are interested in some kind of work and keen on some kind of hobbies, it is not a
bad idea. Turn off the TV 一 this is the opposite of flow 一 and then go outside and do
something that truly makes you active.

     We experience different forms of the Sun's energy every day. We can see its light and feel its warmth.
The Sun is the major source of energy for our planet. It causes the evaporation (蒸发) of water from the
oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These
green plants then provide food for all organisms (生物) on the Earth.
     Much of the energy that comes from the Sun never reaches the Earth's surface. It is either reflected
or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30%
is reflected by clouds or the Earth's surface. The remaining 70% warms the surface of the planet, causes
water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately
0.023%, is actually used by green plants to produce food.
     Many gases found in the atmosphere actually reflect heat energy escaping from the Earth's surface back
to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter
but prevent energy from leaving. They are therefore called greenhouse gases.
     When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount
reflected depends on the surface. For example, you've probably noticed how bright snow is when sunlight
falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter.
Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
1. According to the passage, the root cause for weather changes on the Earth is _____.
A. the atmosphere surrounding the Earth
B. water from oceans and lakes
C. energy from the Sun
D. greenhouse gases in the sky
2. Only a small part of the Sun's energy reaches the Earth's surface because most of it is _____.
A. absorbed by the clouds in the lower atmosphere
B. reflected by the gases in the upper atmosphere
C. lost in the upper and lower atmosphere
D. used to evaporate water from the oceans and lakes
3. We learn from the passage that _____.
A. all living things on the Earth depend on the Sun for their food
B. a forest looks dark in winter because it absorbs solar energy
C. only 0.023% of the energy from the Sun is made use of on the Earth
D. greenhouse gases allow heat energy to escape from the Earth's surface

     We often hear people talking about a generation gap (代沟). The name is new, but the idea
is old. Young people and their parents don't understand each other. The world has always kept
changing. During the second century after Christ a wise man said, "Bury me on my face because
in a little while everything will be turned upside down."
    There has always been a gap between generations, but more people talk about it now. Old
Mr. Ellis thinks he understands what has happened.
    "When I was a boy, I thought the world was a beautiful place. My life was very pleasant. But
when I was older, I learned about people who were treated badly, people who didn't have enough
to eat. I wanted to help them, and I married a girl who wanted to help them, too. We went to
meetings and talked a lot, but it didn't seem to make much difference. "
    "Our children grew up in a world at war. They didn't know when the fighting would stop. They
wanted their children to have nice clothes and toys. They didn't want to think about the future.
They thought nothing could be done about it."
    "Now I have grandchildren, and they have their own ideas. They are trying to make the world
better. They are trying to help other people. They're making people listen to them. I am proud
of their generation."
1. The wise man mentioned in the text told people to bury him on his face so that when everything
is turned upside down he will _____.
A. lie on his stomach        
B. lie on his back
C. stand quietly        
D. sit in peace

D. None of the above.
3. Which generation is/was more efficient in making the world better one?
A. Mr. Ellis' generation.          
B. His children's generation.
C. His grandchildren's generation.
D. None of the above.
4. What is the writer's attitude towards the generation gap?
A. Unacceptable.

D. Common.

     We can achieve knowledge either actively or passively (被动地). We achieve it actively by direct
experience, by testing and proving an idea, or by reasoning.
     We achieve knowledge passively by being told by someone else. Most of the learning that takes place
in the classroom and the kind that happens when we watch TV or read newspapers or magazines is
passive. Conditioned as we are to passive learning, it's not surprising that we depend on it in our everyday
communication with friends and co-workers.
     Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told
even when it is little more than hearsay and rumor (谣言).
     Did you ever play the game Rumor? It begins when one person writes down a message but doesn't
show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn,
whispers it to still another, and so on, through all the people playing the game. The last person writes down
the message word for word as he or she hears it. Then the two written statements are compared. Typically,
the original message has changed.
     That's what happens in daily life. The simple fact that people repeat a story in their own words changes
the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a
story, trying to improve on it, stamping (打上标记) it with their own personal style. Yet those who hear it
think they know.
     This process is also found among scholars and authors: A statement of opinion by one writer may be
re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue,
unless it occurs to someone to question the facts on which the original writer based his opinion or to
challenge the interpretation he placed upon those facts.
1. According to the passage, passive learning may occur in ______.
A. doing a medical experiment
B. solving a math problem
C. visiting an exhibition
D. doing scientific reasoning
2. The underlined word "it" in Paragraph 2 refers to _____.
A. active learning
B. knowledge
C. communication
D. passive learning
3. The author mentions the game Rumor to show that _____.
A. a message may be changed when being passed on
B. a message should be delivered in different ways
C. people may have problems with their sense of hearing
D. people tend not to believe in what they know as rumor
4. What can we infer from the passage?
A. Active learning is less important.
B. Passive learning may not be reliable.
C. Active learning occurs more frequently.
D. Passive learning is not found among scholars.
