     Well, somebody had to be the richest man on earth, but why did it have to be him? William Henry Gates
Bill, now just called "Bill Gates" or "Bill G". William Henry Gates was born in Seattle. In 1973, Gates entered
Harvard University as a freshman (新生). But his heart was not in his studies. After locating (定位) the
school's computer centre, he lost himself in the world of computers once again. Gates would spend many
long nights in front of the school's computer and the next days sleeping in class. So in his junior year, Gates
left Harvard to devote his energies to designing programs for personal computers, which had just entered the
marketplace. In his junior year, Gates left Harvard to devote his energies to Microsoft, a company he had
begun in 1975 with his childhood friend Paul Allen.
     In 1980, the International Business Machines Corporation (IBM) chose Microsoft to develop the operating
system for its first personal computer, the PC. An operating system is a special type of program that contains
instructions for the operation of the computer. Gates devised the Microsoft Disk Operating System (MS-DOS)
for the IBM. Millions of copies of MS-DOS were sold for use in the IBM and IBM-compatible (兼容的) PC's.
     Microsoft continued to grow under Gates' guidance. In 1985, the company introduced the first of a series
of PC programs called windows. These programs enable users to perform multiple (多樣的) tasks through
"windows" on the computer screen and to issue (發(fā)布) commands by pointing at on screen symbols rather
than by typing instructions. Microsoft has sold milljons of copies of windows. In 1998, the United States
Justice Department, along with 20 state attorneys (律師; 代理人) general, filed an antitrust (反壟斷的) lawsuit
against Microsoft. The lawsuit (案件) charged that Microsoft used unfair practices to destroy its competitors.

     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(樂觀) 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(休閑)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 (蒸發(fā)) 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 (代溝). 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."

     We can achieve knowledge either actively or passively (被動地). 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 (謠言).
     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 (打上標記) 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.
