“Did you hear what happened to Adam Last Friday?”Lindsey whipers to Tori.

With her eyes shining,tori brags，“You bet I did,Sean told me two days ago.”

Who are Lindsey and Tori talking about?It just happened to be yours truly,Adam Freedmam,I can tell you that what that what they are saying is (a) not nice and (b) not even true.Still,Lindsey and Tori aren’t very different from most students here at Linton Higt School,including me.Many of our conversations are gossip(闲话)。I have noticed three effects of gossip:it can hurt people,it can give gossipers a strange kind of satisfaction,and it can cause social pressures in a group.

An important negative effect of gossip is that it can hurt the person being talked about.Usually,gossip spreads information about a topic-breakups,trouble at home,even dropping out-that a person would rather keep secret.The more embarrassing or shameful the secret is,the juicier the gossip it makes.Probably the worst type of gossip is the absolute lie.People ofen think of gossipers as harmless,but cruel lies can cause pain.

If we know that gossip can be harmful,then why do so many of us do it?Tht answer lies in another effect of gossip:the satisfaction it gives us.Sharing the latest rumor(传言)can make a person feel important because he or she knows something that others don’t.Similarly,hearing the latest rumor can make a person feel like part of the “in group.”In other words,gossip is satisfying because it gives people a sense of belonging or even superiority(优越感).

Gossip also can have a third effect:it strengthens unwritten,unspoken rules about how people should act.Professor David Wilson explains that gossip is important in policing behaviors in a group.Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said,then you can bet that wearing or saying something similar will get you the same kind of negative attention.The do’s and don’ts conveyed through gossip will never show up in any student handbook.

The effects of gossip vary depending on the situation.The next time you feel the urge to spread the latest news,thing about why you want to gossip and what effects your “juicy story”might have.

Professor David Wilson think that gossip can（）.

A.provide students with written rules

B.help people watch their own behaviors

C.force school to impove student handbooks

D.attract the police’s attention to group behaviors

2000年10月10日，某煤矿采煤区发生一起特别重大瓦斯煤尘爆炸事故，造成162人死亡，37人受伤(其中重伤14人)，直接经济损失达1498.87万元。
该矿的井田走向长8km，倾斜宽0.9～1.9km，面积约12.65km²。该矿的设计年生产能力90万t，矿井可采储量9946万t，服务年限为81年。井田采用平调开拓，单水平上、下山开采。水平标高为+1800m，沿走向划分为8个采区。
该矿通风方式为抽出式，备用2台TZK58N928型轴流式风机，一台运转工作，一台备用。该矿的总排风量为5078m³/min，负压1930Pa。该矿属于高瓦斯矿井，据矿务局有关文件规定，按瓦斯突出煤层管理。矿井绝对瓦斯涌出量29.93m³/min，相对涌出量16.63m³/min(根据1999年瓦斯鉴定结果)。煤尘爆炸指数为27%～36%，具有煤尘爆炸危险。煤层自然发火期8～12月。该矿采区走向长3km，倾斜宽1.4km。采区内沿11号煤层布置皮带、行人和轨道三条下山。皮带下山和行人下山进风，轨道下山回风。该采区开采的11号煤层厚2～3.2m，平均倾角9°，有41112综采和41114高档普采两个工作面生产，41114综采工作面正在安装；41116工作面回风巷、运输巷开切眼，41118工作面运输巷，采区进风行人下山和皮带运输下山6个掘进工作面在施工。
事故发生当年1～10月实际产量82.3万t。全矿有职工2000人，井下分为3个班生产。事故发生时，当班井下有234人作业。41116回风巷掘进工作面因更换局部通风机停电造成瓦斯超限，20点开始排放瓦斯。20点38分，该矿调度室接到电话汇报1740水平车场有股浓烟出来。矿调度立即通知井下作业人员立即撤出，同时向矿领导、矿务局调度汇报，通知救护队进行抢救。23点40分，矿务局有关领导到达该矿，成立了抢险指挥中心，矿务局局长和该矿矿长任总指挥。
事故调查领导小组认为这是一起因矿井生产布局不合理，通风、瓦斯、机电等管理混乱，违章排放瓦斯，现场人员违章拆开矿灯，产生火花引起瓦斯爆炸、煤尘参与爆炸的重大责任事故。
根据以上场景，回答下列问题：

如何处理该爆炸事件

职工与用人单位解除劳动关系取得的一次性补偿收入(包括用人单位发放的经济补偿金、生活补助费和其他补助费用)，在当地上年职工年平均工资3倍数额内的部分，可免征个人所得税。超过该标准的一次性补偿收入，应按照国家有关规定征收个人所得税。( )
