短文填空 从下面方框中选出10个单词并使用其正确形式填入短文空格内,使短文意思正确、通顺(每词限用一次。共10小题,每小题1分;计10分)
he, build, run, easy, get, stand, visit, invent, say, science, France, which
The Eiffel Tower is one of European most famous buildings. It 小题1: in a park near the River Seine in Paris. It is 300 meters tall. It was designed and 小题2: by Alexandre Gustave Eiffel many years ago for Paris Universal Exposition.
“Universal” here means “ of the whole world”, and “exposition” is a place where new 小题3: , new kinds of art and new kinds of the food are displayed.
Eiffel hoped that people could go to the top of the tower 小题4: , so he asked Elisha Otis to design an elevator. Unfortunately, the 小题5: government did not like the first design 小题6: Otis showed them, and they would not let him put the elevator in. In early 1889, the first visitor had to climb hundreds of stairs小题7: to the top.
It’s interesting that Eiffel 小题8: lived in the tower where he had his own apartment. Although Eiffel designed the tower for people to visit, it was also for 小题9: use. Now, the tower gets much more 小题10: than another famous building-the Louvre(卢浮宫).
在回归分析的问题中,我们可以通过对数变换把非线性回归方程y=c1ec2x(c1>0)转化为线性回归方程,即两边取对数,令z=lny,得到z=c2x+lnc1.受其启发,可求得函数y=xlog2(4x)(x>0)的值域是______.

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.
