Sample answer：
I strongly agree with the opinion that cell-phone usage should be banned in some places like concert halls, movie theaters or in some situations like when you are driving in cars or taking a subway, when you are in flight, in classes or meetings.
For one thing, it has become social etiquette(礼节). The cell phone user should know when and where to pick up the cell phone and talk. Though people have personal right to use their phone, the others are not supposed to be involved in(被卷入)
the unnecessary disturbance(不必要的打扰).
For another, cellphone usage can harm a person's health. Brain cancer rates in the US have risen since cellphones were introduced, leading some people to wonder if cellphone usage is the reason for the increase.
In recognition of those above, there should be some kind of regulations helping with this problem. This way people will be well aware.
