being taken seriously by many researchers.
This suggested future for the "red planet" will be the main topic for discussion at an international
conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction
writers will attend the event. It comes as NASA is preparing a multibilliondollar Mars research
programme. "Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael
Meyer, NASA"s senior scientist for astrobiology (太空生物学). "Now, with scientists exploring the
reality, we can ask what are the real possibilities of changing Mars."
Most scientists agree that Mars could be turned into a little earth, although much time and money
would be needed to achieve this goal.
But many experts are shocked by the idea.“We are destroying our own world at an unbelievable
speed and now we are talking about ruining another planet, ” said Paul Murdin, of the Institute of
Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they
will find Martian life forms.Europe and America"s robot explorers have found proof that water, mixed
with soil, exists in large amounts on the planet.
In addition, two different groups of scientistsannounced on March 28 that they had found signs of
methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and
could be produced by microbes (微生物) living in the red planet"s soil.
But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be
put in danger by the little earth project. "Before we have even discovered if there is life on Mars, we are
talking about carrying out projects that would destroy all these native life forms, all the strange microbes
that we hope to find buried in the soil," said Dr Pratt.This view is shared by Monica Grady, a planetary
scientist at the Natural History Museum, London. "We cannot risk starting a global experiment that would wipe out the precious information we are looking for." she said, "This is just wrong."
B. the necessity of changing Mars
C. Mars supporting life
D. finding water in the Mars
B. The project will cost too much money and work.
C. We would ruin Mars.
D. We are destroying our own world at an unbelievable speed.
B. the project will have little effect on the native life forms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
B. Scientists found signs of methane in the Martian atmosphere.
C. Scientists found a lot of good soil on the Mars.
D. Scientists found some creatures living on the Mars.

举一反三
accomplished is not IQ, a generally bad predictor of success. Instead, it"s purposeful
practice. Top performers spend more hours practising their craft. If you wanted to
picture how a typical genius might develop, you"d take a girl who possessed a slightly
above average language ability. It wouldn"t have to be a big talent, just enough so that
she might gain some sense of distinction. Then you would want her to meet, say, a
novelist, who coincidentally shared some similar qualities. Maybe the writer was from
the same town, had the same family background, or shared the same birthday.
This contact would give the girl a vision of her future self. It would give her some
idea of a fascinating circle she might someday join. It would also help if one of her parents
died when she was 12, giving her a strong sense of insecurity and fuelling a desperate need
for success. Armed with this ambition, she would read novels and life stories of writers
without end. This would give her a primary knowledge of her field. She"d be able to see
new writing in deeper ways and quickly understand its inner workings.
Then she would practise writing. Her practice would be slow, painstaking and errorfocused.
By practising in this way, she delays the automatizing process. Her mind wants to turn conscious,
newly learned skills into unconscious, automatically performed skills. By practising slowly, by
breaking skills down into tiny parts and repeating, she forces the brain to internalize a better
pattern of performance. Then she would find an adviser who would provide a constant stream
of feedback, viewing her performance from the outside, correcting the smallest errors, pushing
her to take on tougher challenges. By now she is redoing problems-how do I get characters into
a room-dozens and dozens of times. She is establishing habits of thought she can call upon in order
to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius. It"s the ability to
develop a purposeful, laborious and boring practice routine. The latest research takes some of the
magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is
affected by genetics and what we"re "hardwired" to do. And it"s true that genes play a role in our
capabilities. But the brain is also very plastic. We construct ourselves through behaviour.
B．the relationship between genius and success
C．the decisive factor in making a genius
D．the way of gaining some sense of distinction
B．join a fascinating circle of writers someday
C．share with a novelist her likes and dislikes
D．learn from the living examples to establish a sense of security

D．What really matters is what you do rather than who you are.
changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports.
Grimsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom
different is that it lies under a huge glacier(冰川) of ice up to 12 meters thick. The hot volcano
heats up the ice above it, which then forms a layer(层)of water between the glacier and the volcano.
This layer of water puts pressure on the volcano, keeping it stable. As the water flows out from under
the glacier, the pressure lifts. The lava(岩浆) from the volcano then comes up to the surface. This is
exactly what happened today.
Now, airlines have to make changes to their flights so as not to fly through the clouds of volcanic
ash. According to KLM,one of Europe"s biggest airlines, airplanes cannot go under the cloud or over
it. Going through the cloud can result in ash getting stuck in the airplane"s engines, causing damage to
the plane.
The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp
glasslike rocks all over the countryside. Farmers are keeping their animals inside to stop them from
eating ashcovered grass or the sharp object.
B．It lies under the sea.
C．It is the largest volcano.
D．Its lava affects the airlines.
B．The low water temperature.
C．The thick glacier.
D．The water pressure.
B．Airlines suffer from the loss of planes.
C．It becomes dangerous for animals to eat outside.
D．Farmers have lost many of their animals.
B．a newspaper report
C．a class presentation
D．a geography textbook
towers and street features that appear in the photo.The hyperlinks lead to information about the
history, services and context of all the features in the photo.You have just hyperlinked your reality.
That might be a little unbelievable, but the technology exists and is no fevered imagination.This
is not a cool small machine invented for the next James Bond movie; this is a working technology
just developed by European researchers.It could be coming to a phone near you, and soon.
This, as the marketing types say, is a game changer.It develops a completely new interface
(界面) that combines webtechnology with the real world.It is big and fresh, but it goes much further
and has much greater influence.
The development of the system is most outstanding because image recognition technology has
long been pregnant with promise, but seemed to suffer from an unending labour.
Now MOBVIS has not only developed image recognition; it has also developed more applications
for the technology; and it has adapted it to the world"s most popular technology: the mobile phone.
The MOBVIS system completely rewrites the rules for exploration and interaction with your physical
environment.The system begins with panoramas (一连串景象)．These panoramas form the basis of a
city database.It can match buildings, towers, banners and even logos that appear in the panoramas. A
user simply takes a picture of the street feature, MOBVIS compares the user"s photograph to the
panoramas and then identifies the buildings from the picture you take and the relevant links are returned.
Then you simply click on the links, using a touchscreen phone, and the MOBVIS system will provide
information on the history, art, architecture or even the menu, if it is a restaurant, of the building in question.
B．A popular mobile phone.
C．A cool small machine.
D．An image recognition system.
B．It is a little unbelievable and just a fevered imagination.
C．It has taken an unending labour to bring the technology into our lives.
D．It will encourage the users to take more pictures of the street features.
b．MOBVIS recognizes the picture and links are returned.
c．A user touches the links on the phone screen.
d．A user takes a picture of the street feature.
e．MOBVIS provides information in question.
A．a; e; c; d; b
B．a; d; b; c; e
C．d; c; e; a; b
D．c; a; e; b; d
B．the writer is trying to promote the sales of the MOBVIS system
C．this new technology will soon be very popular in our lives
D．the sales of mobile phones will decrease as MOBVIS comes on market
By generating the proper brainwaves-picked up by a cap with electrodes(电极)that
sense the signals and reflect a person"s instructions-scientists can instruct a humanoid
robot to move to specific locations and pick up certain objects.
The commands are limited to moving forward, picking up one of two objects and
bringing it to one of two locations.The researchers have achieved 94 percent accuracy
between the thought commands and the robot"s movements.
"This is really a proofofconcept demonstration,"said Rajesh Rao,a researcher from
the University of Washington who leads the project."It suggests that one day we might
be able to use semiautonomous robots for such jobs as helping disabled people or
performing routine tasks in a person"s home."
The person wearing the electrode cap watches the robot"s movement on a computer
screen through two cameras installed on and above the robot.
When the robot"s cameras see the objects that are to be picked up they pass on the
information to the user"s computer screen.Each object lights up randomly on the computer
screen.When a person wants something to be picked up and it happens to light up,the brain
registers surprise and sends this brain activity to the computer and then to the robot as the
choice object.The robot then proceeds to pick up the object.
A similar program is used to decide where the robot will go.
"One of the important things about this demonstration is that we"re using a "noisy" brain
signal to control the robot,"Rao said."That means we can only obtain brain signals indirectly
from sensors on the surface of the head,and not where they are generated deep in the brain.
As a result,the user can only generate highlevel commands such as indication which object to
pick up or which location to go to,and the robot needs to be autonomous enough to be able
to execute such commands."
In the future,the researchers hope to make the robot more adaptive to the environment by
having them carry out more complex commands.
B．It can be made humanoid.
C．It can be used to help the disabled.
D．It has high intelligence itself.
B．It can move forward, pick up both objects and bring them to either location.
C．It can only move forward,pick up one object and put it in one location.
D．It can read all human thoughts and do as instructed.
B．will be widely used in our daily routines soon
C．is autonomous enough to complete complex commands
D．is only limited to doing routine work at home
B．how the robot picks up the right object
C．how the person controls the robot
D．how the robot finds out where to go
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 shortterm 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 lifechanging 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.
