综合探究题

据资料显示，我国中小学生每年的非正常死亡人数都在1万人以上。学“灰太狼”烤羊，小学生被烧伤；中学生不堪压力跳楼自杀；还有接连发生的未成年人溺水事故，甚至两天内就有19名中小学生溺亡……未成年人安全问题频出，一桩桩悲剧让人痛心疾首。当前，中小学生安全问题越来越引起人们的高度重视。保护好每一个孩子，使发生在他们身上的意外事故减少到最低，让他们健康安全成长，是学校、社会的共同责任。

（1）上述材料中，未成年人的哪项权利受到侵犯？为什么社会各界要通力配合，共同保护未成年人的这项权利？

（2）面对种种侵害未成年人这一权利的现象，你认为学校、家庭、未成年人自己应如何做？

     Climate scientists hit back at disbelievers yesterday with a new study which brought about the evidence

for man-made global war ming was"stronger than ever".

     After analyzing more than 100 scientific papers published in the last few years, a team of British

researchers say there is an"in creasingly small possibility" that the world is warming up because of natural

variations (变动) in climate.

     Instead, man-made global warming-caused by the burning of fossil fuels-is making its mark on every

continent and ocean, they say.

     The studies used computer models to see whether changes in air temperature, sea ice, sea temperature,

wetness, rainfall and ocean saltiness recorded in the last 50 years could be explained by nature.

     Since 1980,the average global temperature has increased by around0.5℃,they found. The same warming

pattern was also found deep in the world's oceans.

     Natural forces such as volcanic eruptions and returning chan ges in the brightness of the sun could not

explain what was happen- ing to the world's climate, Dr Stott said.

     The sun's output had actually fallen over the last 50 years, he said.

     Even if the sun had got warmer over the last few decades-as some skeptics say-both the upper and lower

layers of the atmos phere should have got hotter.

     However, in the last 50 years the lower atmosphere has warmed while the upper atmosphere has actually

cooled, Dr Stott said.

     Drier parts of the world are getting drier, while wetter areas are getting more rain-a finding in agreement

with man-made climate change, the report found.

     And the amount of mid summer sea ice in the Arctic is also declining over time-even with the natural

yearly variations, the study found.

     The study comes along with growing public doubt about climate change.

甲向乙借款5000元，并把自己所有的价值8000元的摩托车一辆质押于乙，双方签订了书面合同，合同约定，若甲到期不能还款，则该摩托车即归乙所有。合同签订后，甲即将摩托车交付乙占有。因甲到期无力还款，乙即将摩托车推出自己使用。使用中，因不慎致使摩托车部分零件损坏，遂将车交付丙修理。丙修理后，因乙认为修理费不合理，拒绝交付修理费，摩托车被丙留置。在丙占有期间，因修理铺被盗，摩托车被偷走，案件至今未破。就此，当事人发生争议。下列表述中正确的是( )。

A．该车的损失应由甲承担，因甲为车的所有权人
B．该车的损失应由乙承担，因乙为车的所有权人
C．该车的损失应由丙承担，因在丙占有期间被盗
D．该车的损失应由乙承担，因乙为有过错的质权人
