求翻译：比如说学生们在上课发短信，或者玩游戏，这是不利的，也是不对的。当然，如果说，上课期间一直关机，直到放学才开机，这是对的。是什么意思？

For example, students in the class texting or playing games, which is unfavorable, is also wrong. Of course, if during the school has been shut down, until the school before boot, which is right.

For example, a short letter from students in the classroom, or play the game, this is negative, it is also wrong. Of course, if it is said that during class, which has been shut down, it was not until after school, this is only for the machine.

For instance said the students are attending class send the short note, or plays the game, this is disadvantageous, also is not right.Certainly, if, attends class the period closes down continuously, until is on vacation from school only then starting, this is right.

Texting in class, the students, for example, or playing a game, this is undesirable, are wrong. Of course, if you say, has been shut down during the class, only school until the power on, this is on.
