Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer.

This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended (混合) with flexible electronic materials to create intelligent clothing. The results are electronic garments.

If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-­free, soft to touch and washable! Like any electronic device, these high-­tech clothes have to be powered. Currently, a tiny nine-­volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100% shock ­proof, they say.

The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These “lap-­tap” gadgets (器具)are all set to take over laptop computers!

Another useful garment is the shirt­-cum-­mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(风帽) and the electronic ski jacket with a built-­in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?

2010年10月26日，某铁矿发生火灾事故，由于该矿和临矿互通，火灾共涉及5个铁矿，造成百人被困井下。经多方抢救，遇难矿工人数仍达70人。随即成立了国务院事故调查组，调查组由国家安全生产监督管理总局、监察部、全国总工会、国土资源部、省人民政府联合组成，分为综合、技术、管理三个组。国务院事故调查组经初步调查，认定事故发生的直接原因是：维修工在井筒内使用电焊，焊割下的高温金属残块及焊渣掉落在井壁用于充填护帮的荆笆上，造成长时间阴燃，最后引燃井筒周围的荆笆及木支护等可燃物，引发井下火灾。5家矿山越界开采，造成各矿井下巷道贯通，风流紊乱，火灾烟气蔓延，各矿均未按要求设置井下作业人员逃生的安全通道，直接导致了事故的升级和扩大。

根据以上场景，回答下列问题

按照《关于做好生产安全事故调查处理及有关工作的通知》的有关规定，一次死亡30人以上(含30人)的特别重大事故和党中央、国务院领导同志有明确指示的特大事故以及社会影响大的未遂事故的有关信息和情况，由( )在中央新闻媒体上予以披露、报道与曝光。

A．安全监管总局的有关部门

B．省安全生产监督管理局

C．国家劳动保障部门

D．国务院新闻办公厅

E．省、自治区和直辖市人民政府
