如图所示，在xoy平面内，MN与y轴平行，间距为d，其间有沿x轴负方向的匀强电场．y轴左侧有垂直纸面向外的匀强磁场，磁感应强度大小为B₁；MN右侧空间有垂直纸面的匀强磁场（磁场方向未标出）．质量为m、电荷量为q的粒子以v₀的速度从坐标原点o沿x轴负方向射入磁场，经过一段时间后再次回到坐标原点，此过程中粒子两次通过电场，在电场中运动的总时间t_总= $\frac{4d}{3v_0}$ ．粒子重力不计，求：

1939年2月5日，***在中央党校《关于反对投降主义》的演讲中说：共产党人要为共产主义奋斗，这是确定无疑的，但“现在一定要走三民主义”，这是“到共产主义的必经之路”。***提出“现在一定要走三民主义”道路的主要依据是（  ）

    In some science fiction movies，the robots are just like humans. They help with the housework and do the most 1 jobs.

    Some scientists believe that there will be such robots in the future.2, they agree it may 3hundreds of years. Scientists are now trying to make robots 4people and do the same things as us.

    But robot scientist James White 5. He thinks that it will be 6 for a robot to do the samethings as a person. 7 , it's easy for children to wake up and know where they are. Mr White thinks that robots won't be able to do this. But other scientists disagree. They think that robots will be able to talk to people 8 25 to 50 years.

    Robot scientists are not just trying to make robots look like people. For example, there are already robots 9 in factories. They do simple jobs over and over again. People would not like to do such jobs and would get bored. But robots will 10 get bored.

    In the future，there will be more robots everywhere，and humans will have 11 work to do. New robots will have many different 12. Some will look like humans, and 13 might look like snakes. After anearthquake（地震），a snake robot could help look for people under buildings. That may not seem possible now, but computers, space rockets and even electric tooth brushes 14 impossible a hundred years ago. We never know 15 will happen in the future!
