Erica David lives in Pinedale,Wyoming,USA,where winter can bring temperatures of below 35 degrees Fahrenheit,howling winds,and a lot of snow.So it was just natural that she chose to study snow for her school science fair in the sixth grade.
Now a junior in high school,Erica is in her sixth year of snow experiments,and is well on her way to becoming a snow expert.She started with a basic question:Could snow fences be built to work better?
Snow fences are used to keep snowdrifts(雪堆)from covering areas like roads of train tracks,or to help build up snow where it can help with water shortages in spring when it melts(融化).“Also,I wanted to protect my animals better from blowing snow,”says Erica,who raises goats,sheep,and pigs.
Before she could test fence designs,Erica had to figure out what would act like real snow in her experiments. “I tested flour, sugar, and salt before I settled on dishwasher powder , ”she explains.
Science fairs offer students the chance to test theories, present findings to judges, and meet other researchers. Erica’s many achievements include competing at the Discovery Channel Young Scientist Challenge for middle school students and the Intel International Science and Engineering Fair, where students from around the world present their science research.
But perhaps the best reward is that her research is already being put to good use. She has come up with an improved snow fence design, and this year she’s helping think out how to provide water supply to native plants, which have been killed off by drilling at nearby natural gasfields.
“Science fairs are an amazing experience,”says Erica. “Just pick your true feeling and go for it. ”
72. What does the passage suggest to us?
A. Science fairs are held for high school students in America.
B. Erica is the youngest show expert well known in America.
C. The environment brought much convenience for Erica to study snow.
D. The hope to contribute to her hometown made Erica experiment on snow.
73. In Erica’s hometown, snow fences may play a part in ________.
a. reducing the harm blowing snow does to animals
b. supplying water resource to the nearby gas fields
c. making up for the lack of water resource.
d. keeping the traffic smooth
A. a,b,c          B. a,b,d             C. b,c,d            D. a,c,d
74. Science fairs are attractive to students because they ________.
A. can have their research put into practical use
B. can have their scientific ideas tested out
C. are allowed to help protect the local wildlife

阅读理解。
     Scientists have created a way to control a robot with signals from a human brain.
     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.
1.What is special about the robot introduced in the passage?
A.It is controlled by human thoughts.
B.It can be made humanoid.
C.It can be used to help the disabled.
D.It has high intelligence itself.
2.Which of the following is TRUE about the robot?
A.It can move forward and backward and pick up two objects at the same time.
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.
3.What Rao says in the eighth paragraph suggests that the new robot________.
A.is still at its early stage of development
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
4.The sixth paragraph mainly describes________.
A.how the robot controls a person's action
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
