距开始使用平板电脑已经好几个星期了，从一开始的不适应，到现在的渐渐得心应手，同学们真是进步良多！看到他们打字速度的进步，身为旁观者的笔者也甚为高兴。

It has been a few weeks since the students started to use tablets for their works. They had met with some technical glitches in the beginning, but now they have already gotten used to it. There is an obvious improvement in terms of the speed and efficiency with which they key in their answers.
