A study involving 8,500 teenagers from all social backgrounds found that most of them are ignorant when it comes to money. The findings, the first in a series of reports from NatWesl that has started a five-year research project into teenagers and money, are particularly worrying as this generation of young people is likely to be burdened with greater debts than any before.

University tuition fees (学费)are currently capped at £3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.

In the research, the teenagers were presented with die terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average £ 31.000 by the age of 25, although the average salary for those aged 22 to 29 is just £ 17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than £ 10.000. Average debts for graduates are £ 12,363.

Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they are to become responsible, forward-planning adults who manage their finances confidently and effectively."

Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweather aged 15 from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money.

实验题

一天,小明放学回家看见他妈妈炒菜时油着火了,妈妈迅速盖上锅盖,一会儿火灭了。小明很好奇,想对物质燃烧及灭火原理探个究竟。于是,他同到学校询问了化学老师,老师没有回答他的问题,只是给他作了以下四个实验:

①用坩埚钳分别夹取石子和一片纸在火上烧,只有纸燃烧;

②同时取等质量的两小块儿白磷,分别放在如下图A、B所示的铜片上,一段时间后,只有装置A 的白磷燃烧:

③将燃着的小木条分别插入盛有以上气体的集气瓶中(见图中C、D所示),C瓶空气,D瓶是氧气已耗尽的空气,发现小木条插入D瓶中马上熄灭,插入C瓶的过了一段时间才熄灭;

④将在空气中点燃的小木条,插入盛有氧气的集气瓶中,发现水条燃烧的更旺。

请回答下列问题:

(1)请你帮助小明分析物质燃烧的条件是______________。

(2)从实验④中你可以得出的实验结论是______________。猜想物质着火燃烧的剧烈程度,还可能与哪些因素有关?设计实验方案加以验证________。

(3)结合上述实验或物质燃烧的条件,总结灭火的原理(最少两条)。①______;②______。

回想生活中你见到的灭火场景,思考这些灭火的方法利用了灭火的哪条原理?(课后与你的同学进行交流)。举1例即可______________。

(4)在农村,有时堆放的秸秆会发生自燃现象,发生这种现象的原因是____________,请你为避免这种现象的发生提一些建议(至少2条)。①___________________;②_________________。
