that time, large computers were only used by large, rich companies that could afford the investment. With
the advancement of technology, small computers have come onto the market, which are capable of doing the
work that used to be done by much larger and expensive computers, so now most smaller companies can use
them.
The main development in small computers has been in the field of word processors (处理器), or WPS as
they are often called. 40% of British offices are now estimated to have a word processor and this percentage
is growing fast.
There are many advantages in using a word processor for both the secretary and the manager. The
secretary is freed from a lot of daily work, such as retyping letters and storing papers. He or she can use this
time to do other more interesting work for the boss. From a manager"s point of view, secretarial time is being
made better use of and money can be saved by doing daily jobs automatically outside office hours.
But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that
fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual
display units (显示器). The case of a slow loss of sight among people using word processors seems to have
risen greatly. It is also feared that if a woman works at a VDU for long hours, the unborn child in her body
might be killed. Safe screens to put over a VDU have been invented but few companies in England bother to
buy them.
Whatever the arguments for and against word processors, they are a key feature (特征) of this revolution
in office practice.

homework as a way to avoid following your directions. Before you know it, you"ve started to sound like
a broken record as you repeatedly ask them to do their assignments, clean their rooms, or take out the
trash. Rather than saying "Do your chores now." you"ll be more effective if you set a target time for when
the chores have to be completed. So instead of arguing about starting chores, just say, "If chores aren"t
done by 4 pm, here are the consequences." Then it"s up to your child to complete the chores. Put the ball
back in their court. Don"t argue or fight with them, just say, "That"s the way it"s going to be." It shouldn"t
be punitive (惩罚性的) as much as it should be persuasive. "If your chores aren"t done by 4 pm, then no
video game time until chores are done. And if finishing those chores runs into homework time, that"s going
to be your loss." On the other hand, when dealing with homework, keep it very simple. Have a time when
homework starts, and at that time, all electronics go off and do not go back on until you see that their
homework is done. If your kids say they have no homework, then they should use that time to study or
read. Either way, there should be a time set aside when the electronics are off.
When a kid wears his iPod or headphones when you"re trying to talk to him, make no bones about it;
he is not ignoring you, he is disrespecting you. At that point, everything else should stop until he takes the
earplugs out of his ears. Don"t try to communicate with him when he"s wearing headphones-even if he tells
you he can hear you. Wearing them while you"re talking to him is a sign of disrespect. Parents should be
very tough about this kind of thing. Remember, mutual respect becomes more important as children become
mature.
B. parents" directions sound like a broken record
C. children are ready to follow their parents" directions
D. parents are unaware of what they are repeating to their kids
B. make them do things at their request
C. argue and fight with their children
D. allow their children to behave in their own way
B. can do whatever they like
C. can stay aside watching TV
D. must switch off the power
B. it will make no difference that a kid is wearing his earplugs while talking to his parents
C. parents shouldn"t give in to their kid when he shows no sign of respect
D. kids" purposely talking to their parents with iPod gives them a sense of power and control
B. how kids behave to ignore and disrespect their parents
C. that children should make choices and decisions on their own
D. how parents can deal with their kids" behavior effectively
something with so few apparent benefits? Why should resources be spent on space rather than on conditions
and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup (基因构成) as human beings. What drove our ancestors
to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of
a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency
to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas
can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With
knowledge, we can lessen its effects.
Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no
immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions.
Knowledge or techniques have been acquired through exploration. The techniques may have medical applications
which can improve the length or quality of our lives. We have already benefited from other spin-offs including
improvements in earthquake prediction, in satellites for weather forecasting and in communications systems.
Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in the
space, the chance to save ourselves might not exist.
While many resources are spent on what seems a small return, the exploration of space allows creative,
brave and intelligent members of our species to focus on what may serve to save us. While space may hold
many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The
danger exists, but knowledge can help human being to survive. Without the ability to reach out across space,
the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us
to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted
in the past and surely could in the future.
B. To compare different ideas.
C. To introduce points for discussion.
D. To describe the conditions on Earth.
B. Humans have the tendency to fight.
C. Humans may find new sources of food.
D. Humans don"t like to stay in the same place.
B. potential resources
C. unexpected benefits
D. physical possessions
B. Resources on the earth.
C. The adaptive ability of humans.
D. By-products in space exploration.
B. Space exploration provides the best value for money.
C. Space exploration can benefit science and technology.
D. Space exploration may help us avoid potential problems on Earth.
they receive their elementary and high school education by working at home on computers. The center
for Education Reform says the United States has 67 public "cyberschools" and that is about twice as many
as two years ago.
The money for students to attend a cybersehool cotes from the governments of the states where they
live. Some educators say cyberschools receive money that should support traditional public schools. They
also say it is difficult to know if students are learning well.
Other educators praise this new form of education for letting students work at their own speed. These
people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say
learning at home by computer ends long bus rides for children who live far from school.
Whatever the judgment of cyberschools, they are getting more and more popular. For example, a new
cyberschool called Commonwealth Connections Academy will take in students this fall. It will serve children
in the state of Pennsylvania from ages five through thirteen.
Children get free equipment for their online education. This includes a computer, a printer, books and
technical services. Parents and students talk with teachers by telephone or by sending emails through their
computers when.necesary.
Students at cyberschools usually do not know one another. But 56 such students finished studies at
Western Pennsvlváni? Cyber Charter School recently met for the first time. They were guests of honour at
their graduation.
B. They study at home rather than in classrooms.
C. They receive money from traditional public schools.
D. They do well in traditional school programs.
B. They get little support from the state government.

D. The students find it hard to make friends.
B. their students can work at their own speed
C. their graduates are more successful in society
D. they serve students in a wider age range
B. excited about the future of cyberschools
C. doubtful about the quality of cyberschoois
D. disappointed at the development of cyberschools
Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit-and that can
be a very annoying thing. 1_____ Read on for some techniques worth trying.
1. 2_____
People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance
of Alzheimer"s disease (早老性痴呆症), according to a recent study.
3_____
Something as simple as setting a goal to have a weekly coffee date with a friend will do. There"s evidence
that people who have a purpose in life or who are working on long or short-term goals appear to do better. In
other words, keep your brain looking forward.
2. Go for a walk.
Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and
physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that
are good for your brain. 4_____
3. Learn something new.
Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation
(刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when
you learn something new and are physically active at the same time. 5_____ Or go dancing with your friends.
B. This can be especially harmful to the aged.
C. It should be something like learning gardening.
D. So take a few minutes each day to do some reading.
E. But don"t worry if your schedule isn"t filled with life-changing events.
F. Luckily, research shows there is a lot you can do to avoid those moments.
G. In other words, when you take care of your body, you take care of your brain.
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.
B. water from oceans and lakes
C. energy from the Sun
D. greenhouse gases in the sky
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
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
