One
of
the
greatest
mysteries
in
biology-how
the
monarch
butterfly
(
帝王蝶
)
travels
thousands of kilometers on its yearly migration (
迁移
)-has just been solved.
Monarch
butterflies
use
the
sun
to
set
their
body
clocks
and
make
their
journeys,
according to US scientists. No other butterfly in
the world migrates like the orange and
black monarchs of North America. They cannot live for long periods in cold weather. Each
autumn, thousands travel up to 3,000 km to spend the winter in the mountains of Mexico.
There are so many, they almost block out the sky, and you can hear their wings beating.
It usually takes the butterflies two months to reach Mexico. After staying five months,
they head back up north in the spring. But not one butterfly finishes the whole round-trip.
They lay eggs along the way and die.
Three generations of butterflies will live and die during the spring journey alone. The
fourth and final generation of the year is born in early autumn and will reach the north.
But it hardly gets to rest before starting the long journey south to Mexico.
The most amazing thing about these butterflies is that they return to the very same tree
in
Mexico
that
their
great-great- grandparents
used
the
winter
before.
Past
studies
have
shown
that
the
insects
use
the
sun
as
a
compass
(
指南针
)
to
show
them
the
way.
But
experts are unsure how the butterflies change their direction as the sun moves in the sky.
This new study now shows that the insects use a
“
circadian (
生理节奏的
)
”
clock in
their
bodies
as
part
of
their
sun
compass.
In
laboratory
tests,
monarch
butterflies
were
found to fly in the right direction under normal daylight hours. But those flying in 24-hour
light headed straight towards the sun. That is, they no longer had any sense of time.
Scientist Steven Reppert, who led the research, said:
“
We have shown the need for the
circadian clock for monarch butterfly migration. When the clock is interrupted, monarchs
are unable to fly towards Mexico.

At present, there are many ways to travel, that is, we can choose different ways to go
to some place.
In China, more and more people have their own cars. Therefore, the roads are getting
busier and busier and sometimes there are many traffic jams, especially in the big cities.
How can we solve this problem? On the earth the population is growing larger and larger
and there will be less and less space. So some scientists are trying to make a new kind of
car-a flying car. A flying car is a car that not only runs on the road, but also flies in the sky
whenever there is heavy traffic. It is just like a bat (
蝙蝠
), as it has wings. When the car
runs on the ground, the wings are folded. However, when it flies, the wings are unfolded.
It can fly at the height of 1,500-3,000 meters, and it can fly at the speed of 600 kilometers
per hour.
There will be another kind of train in the future. Maybe it will be called the
“
flying
train
”
- it looks like a plane, but it has no wings. It can run near the ground but it doesn
’
t
touch
the
ground.
It
will
be
much
faster
than
any
train
currently
available.
A
Japanese
scientist says this kind of flying train can be made by the year 2020.
So, perhaps it is possible that cars and trains can fly in the sky in the future. Actually,
the future plane may fly not only in the sky, but also under-ground. Yes, it will be called
the
“
underground plane.
”
At present, it is still just an idea in scientist
’
s mind. According to
the idea, an underground plane has two storeys, It can hold 400 people. The plane will be
50 meters long, four meters tall and over two meters wide. It will be a rectangle (
长方形
).
Its wings are in the middle of the plane. At the bottom, there are two pairs of wheels. They
are used when the plane lands. When this plane is flying, it is one meter above the ground.
Some scientists think that this kind of plane is better than the airplanes we have now.
(Words: 368)
1.
Why do scientists want to make
“
flying car
”
and
“
flying train
?”
A) Because the roads are getting more and more crowded.
B) Because the population on earth is increasing.
C) Because we will have less and less space.
D) Because people need new modes of transportation.
2.
A flyin care_________.
A) folds its wings when it runs on he ground
B) flies in the sky as its name indicates
C) keeps its wings unfolded.
D) is even faster than future planes
3.
Which of the following statements is true about the
“
flying train?
”
A) It looks just like a plane with no wings.
B) It can fly or run directly on the ground.
C) A Japanese is hopeful of making one such train.
D) It may be available by 2020.
4.
What will the future plane be like?
A) It flies underground as well as in the sky.
B) It has two stories in the shape of a square.
C) It has two pairs of wheels in the middle.
D) It flies one meter under the ground.
5.
It can be seen from the passage that_________.
A) the modes of future transportation are unknown
B) the Japanese are ahead in terms of technological know- how
C) the potential of creativity is unlimited
D) people can do whatever they think of

Teaching
developmental
writing
in
a
community
college
is
a
job
I
never
dreamed
of
doing.
I
had
planned
to
be
a
journalist.
That
changed
after
my
second
failed
attempt
at
newspaper reporting. I moved back to Indianapolis and, four months later, began teaching.
Then I met Steve, a student who was just like I was many years ago. At the beginning of
the semester I gave my class a copy of Hubbard
’
s Message to Garcia. After I explained the
essay
’
s contents, I drew their attention to one passage:
“
It is not book-learning young men
need,
nor
instruction
about
this
or
that,
but
a
stiffening
(
变硬
)
of
the
vertebrae
(
脊椎
)
which will cause them to be loyal to a trust, to act promptly (
迅速地
), concentrate their
energies; do the thing-carry a message to Garcia !
”
Then I told them my
story. I explained to them that my high school advisor told me,
“
You have a great deal of potential.
”
He was referring to my careless habits that affected
my school work. Later, in college, I understood he was right. I carried my bad habits with
me,
and
by
the
end
of
my
sophomore
(
大二
)
year,
I
had
been
kicked
out
due
to
my
below-average grades.
The following year, I worked in a café
, rented a room, and steadily rebuilt my academic
ability by taking independent study courses. Once I had reestablished my self-confidence,
I enrolled in regular classes. During that lonely year, I read. That was when I discovered
Hubbard
’
s writing.
Two
years
later,
I
graduated
from
college
and
became
a
reporter.
At
two
different
newspapers, I bungled (
搞砸
) my job.
During
a
brief
time
of
unemployment,
I
re-read
Hubbard
’
s
“
Message.
”
Four
months
later I was offered a job as a teacher and as a tutor.
Every year my students hear this story, and I tell them how they should make good use
of their potential. When I first met Steve I told him along with the rest of the class, that
succeeding
in
my
course
would
only
come
from
their
“
acting
promptly
”
and
“
concentrating their energies
”
.
He then said
he didn
’
t
need my
class, and didn
’
t
see the
point in writing well.
At semester
’
s end, I returned their final assignment and wondered if they
’
d gotten my
message.
Steve
didn
’
t
pass
the
class.
In
his
essays,
I
wrote,
“
You
have
a
great
deal
of
potential
”
and left another copy of Hubbard
’
s essay. I hope he gets the rest of the message
quicker than I did.
(Words: 409)
(
) 1. The writer was forced to leave college at the first semester due to poor academic
work.
(
) 2. The writer came across Hubbard
’
s writing when he felt lonely and helpless.
(
) 3. After leaving college, the writer realized that his high school advisor was right.
(
) 4.
Message to Garcia
tells us about the importance of book- learning.
(
) 5. The passage is about how the author regained his self-confidence after overcoming
his shortcomings, and how he shared it with his students.
