很多小孩都希望通过电子设备来读书。而如果他们拥有电子书的话，他们乐于阅读的频率会高些。
Many children want to read books on digital devices and would read for fun more frequently if they could obtain e-books.
因为该装置使用的电磁频率较低，体外阅读器可距其较远。
Because the electromagnetic frequencies it uses are low, the reader can be farther away.
电子阅读给我的感觉就像是一个频率的列表，我只要瞥一眼这个列表，就能知道这本书对我的研究可能会有怎样的帮助。
An electronic reading supplies me with a list of the frequencies, which I have only to glance at to form an idea of the problems the book suggests to my critical study.
