Since the first person walked on the moon in 1969, technology has greatly helped space exploration, In recent years scientists have built a special robot to accompany astronauts on space missions (任务). Because this robot look sand moves like a person, scientist a call it a humanoid robot. The latest model of the humanoid robot is known as R2, short for Robonaut 2.
R2 wan first launched into space on February 24, 2011. It was built by the
National Aeronautic sand Space Administration (NASA) and the car producer General Motors (GM).
R2 weighs 330 pounds and costs $2.5 million to build. It has arms and a head—filled with vision—equipment but no legs. Its“ brain”, or computer, is in its stomach. R2's arms can hold 20pounds. Each bendable finger has 5 pounds of grasping force. R2's hands are also skilful. Since it’s hands are shaped like human hands, R2 can use human tools to complete tasks traditionally performed by astronauts,“Astronauts absolutely have their day packed from the minute they wake up until they go to bed. If Robonaut can provide just an hour's worth of relief to the astronauts doing something they don't want to do, that would make it worth it right there,”says Nic Radford,the deputy project manager of R2.
One advantage of working with R2 will be that it can't complain about its work! Astronauts will also appreciate the fact that the robot can perform its duties without constant supervision ( 监管). R2 can be assigned a talk and then checked on periodically. If R2 does not complete a task correctly, astronauts will- be able to make minor adjustments to adapt (适应) the robot's behavior so that the task gets done tight.
R2 is still in the design stage of development, which means that scientists are frequently testing it and looking for ways to improve it. Right now, humanoid robots do not have the protective equipment needed to work outside the space station. As technology advances, humanoid robots will be able to help astronauts with dangerous tasks as well as routine ones. In the future, humanoid robots will be astronauts’ eyes in space, going, to places considered to difficult or unsafe for astronauts to explore. Some of them will be mounted on wheels to explore the surface of planets or asteroids (小行星). The robots will be able to send back videos and help astronauts gather information about the atmospheres of these places. One outcome of using these humanoid robots will be a greater understanding of the interaction between humans and robots. NASA engineers believe that when humans and robots combine forces and work together, the results will be better than what either could achieve alone, John Olson, a director at NASA headquarters in Washington, D.C.， says that the project will allow us to go farther and achieve more than we can probably even imagine today. 52.

All Together Now!
Have you ever heard of homemade music? That's right homemade music. Music that is made at home can be lots of fun. And all of the family can take part in it. You don't have to have god voices. And you don't need to buy a musical instrument. What a family needs in the willingness to make music.
A singing game my family like is Crazy Voices. Each person sings a different song. But everybody sings at the same time! We do sound a little
crazy. But the tunes (曲调) all fit together. Sometimes we get all mixed up. Then we just hum the songs. Or we put our hands over our ears. Then we try it again. And crazy voices fill the air.
We really have homemade music when we play the Tap-a-Glass. Why? We make the instrument—that's the Tap-a-Class. This takes some time. First, we hunt for drinking glasses that have a good ring to them. We tap therm with a spoon to find out. We need eight glasses—one for each tone (音调) of the scale. How do we get different tones? By putting different amounts of water in the glasses. The more water,the lower the tone. After a while, we have all eight tones of the scale, Now the Tap-a-Glass is ready.One person takes the spoon and taps out a simple tune. We always give the player time to practice a little bit first. 'Then we try to guess the name of the song.
