Directions: Read the following passages
carefully and choose
the best answer from the
four choices marked A, B, C and D.
Questions 1
to 5 are based on the same passage.
The crop
circles you will see as part of the Crop Circle
Connector
web site are actual events that have
taken place in crop fields
worldwide. This web
site is literally the largest crop circle site on
the
Internet. On this site you will find
information to cater for all your
needs
including an international crop circle database.
In the UK farmers recall simple circles
appearing on their land for
generations. The
British media first reported on the circles in the
early 1980s. By 1990 crop circles had exploded
into the public mind
as the new phenomenon
changed from simple circular patterns into
huge and complex, geometric formations. The
crop circles are a
worldwide phenomenon and
each year new reports come from an
ever
increasing number of countries. However, the main
concentration of events are to be found in
Southern England, many
around ancient sites
such as Stonehenge, Avebury and Silbury Hill.
Although there are many theories as to their
creation, none have
been able to explain
satisfactorily exactly how the circles are made.
But, perhaps some of the most persuasive
evidence comes in the
form of videotaped
footage showing small bright balls of white light
in and around the crop circles. Many of these
lights have been
filmed in broad daylight and
the objects seem to move with purpose
and
intelligence. Could this hint at a possible link
between them
and the formation of crop
circles?
Scientific analysis has been carried
out on plant samples taken
from the crop
circles. The work done suggests that some sort of
microwave energy effect is involved in the
circle making process.
Crop circle researchers
are increasingly being asked to use
creative
and innovative thought as part of their
investigative
process. Some current field
research uses meditation, lights and
musical
sounds in an effort to communicate new patterns
into the
fields as the circles phenomenon has
been seen to interact with the
human mind.
Whatever the crop circles are, they have
perplexed and inspired
people worldwide. For
those involved it has changed their lives
forever, with the growing realization that we
live in a world that is
infinitely more
complex and mysterious than we could have
imagined.
This web site is
dedicated to bringing you the very latest and most
comprehensive crop circle news and
information. We incorporate
reports on all the
new formations with top quality photographs from
some of the foremost researchers and
photographers.

Questions 6 to 10 are
based on the same passage.
Japan's famed
cherry trees have carried the hearts of a nation
for
centuries but they will soon enjoy another
honor—their seeds being
launched into outer
space.
The Japan Aerospace Exploration Agency
(JAXA) has approved a
project to send the
seeds of cherry trees to the Japanese laboratory
at the International Space Station, officials
said Tuesday.
Japan Manned Space Systems
Corp., a Tokyo-based
private-sector consortium
of 55 companies, organized the cherry
seeds'
half-a-year stay in space in part to see whether
or how
microgravity would affect them.

ordinary people can go now,
Manned Space
Systems spokeswoman Yuko Otake said.
Cherry
trees' annual springtime blooming is a time for
nationwide
enjoyment in Japan, where friends
and colleagues hold picnics to
enjoy the
short-lived beauty of the blossoms.
The space
project will send lily and violet seeds along with
the
seeds from 10 cherry trees, including
three designated by the
government as natural
treasures and praised as producing Japan's
most beautiful blossoms.
One of the three
ancient trees, named Takizakura, or
cherry
blossoms,
in bloom in the small northern
town of Miharu.
Elementary school pupils in
Miharu will pick some 200 fallen seeds
in June
or July for the space project. The town will share
the
returned seeds with research institutions.

promote tourism here while
drawing children's
interest in science,
said.
The town will
also plant some seeds, he said.

The seeds will be lifted
off into space around October and are

Questions 11 to 15 are based on
the same passage.
South Korean scientists say
they have engineered four beagles (比
格犬) that
glow red using cloning techniques that could help
develop cures for human diseases.
The four
dogs, all named —a combination of the words
—look like typical beagles by daylight. But
they
glow red under ultraviolet light.
Seoul National University professor Lee
Byeong-chun, head of the
research team, called
them the world's first transgenic dogs
carrying fluorescent genes, an achievement
that goes beyond just
the glowing creation.
Who will pick fallen cherry seeds in Miharu?
A. The elementary school students.
but that we planted genes into
them,
Tuesday.
His team identified the dogs
as clones of a cell donor through DNA
tests
and earlier this month introduced the achievement
in a paper
on the website of a journal.
Scientists in the US, Japan and in Europe
previously have cloned
fluorescent mice and
pigs, but this would be the first time dogs with
modified genes have been cloned successfully,
Lee said.
He said his team took skin cells
from a beagle, inserted fluorescent
genes into
them and put them into eggs before implanting them
into
the body of a local mixed breed.
Six
female beagles were born in December 2007 through
a cloning
with a gene that produces a red
fluorescent protein that made them
glow, he
said. Two died, but the four others survived.
The glowing dogs show that it is possible to
successfully insert
genes with a specific
trait, which could lead to implanting other,
non-fluorescent genes that could help treat
specific diseases, Lee
said.
The scientist
said his team has started to implant human
disease-related genes in dog cloning, saying
that will help them find
new treatments for
genetic diseases such as Parkinson's.
A South
Korean scientist who created glowing cats in 2007
based
on a similar cloning technique said that
Lee's puppies are genuine
clones, saying he
had seen them and had read about them.

specific diseases Lee's team
will focus on.

Questions 16 to
20 are based on the same passage.
Robots could
fill the jobs of 3.5 million people in Japan by
2025, a
think-tank says, helping to alleviate
worker shortages as the
country's population
shrinks.
Japan faces a 16 per cent drop in the
size of its workforce by 2030
while the number
of elderly will mushroom, the government
estimates, raising worries about who will do
the work in a country
unused to, and unwilling
to think seriously about large-scale
immigration.
The think-tank, the Machine
Industry Memorial Foundation, says
robots
could help fill the gaps, ranging from micronized
capsules
that detect problems to high-tech
vacuum cleaners. Rather than
each robot
replacing one person, the foundation said in a
report
that robots could make time for people
to focus on more important
things.
Japan
could save 2.1 trillion yen (10.4 billion pounds)
of elderly
insurance payments in 2025 by using
robots that monitor the health
of older
people, so they do not have to rely on human
nursing care,
the foundation said in its
report. Caregivers would save more than
an
hour a day if robots helped look after children,
older people and
did some housework. Robotic
duties could include reading books
out loud or
helping bathe the elderly.
old, day care
centers are being built so that more women can
work
during the day, and there is a move to
increase the quota of foreign
laborers. But
none of these can beat the shrinking
workforce,
Takao Kobayashi, who worked on the
study.
because they could help in some ways to
relieve such shortage of
the labor
force.
The current fertility rate is 1.3 babies
per woman, far below the level
needed to
maintain the population, while the government
estimates
that 40 percent of the population
will be over 65 by 2055, raising
concerns
about who will look after the graying population.
Kobayashi said changes were still needed for
robots to make a big
impact on the workforce.
functions of the robots still need to improve,
and then there are the
mindsets of
people,
the robots.
16.
What is the main
idea of this passage?
A. Robots will play a
very important role in society.
B. Robots
can relieve shortage of the labor force.
C. Robots will change people's life style.
D. Robots can save time for people.

Which of the following best describes
what robots could do in
the future?

people.
C. They could monitor the health
of older people.
D. They could do various
things to make time for people.
