    陈希亮,字公弼。幼孤好学,年十六,将从师,其兄难之,使治钱息三十余万。希亮悉召取钱者,焚其券而去。业成,乃召兄子庸、谕使学,遂俱中天圣八年进士第。初,希亮以母老,为县侍亲。母终,服除,为开封府司录司事。期年,殿侍雷甲以兵百余人逐盗竹山,甲不能戢,所至为暴。或疑为盗,告希亮盗入境,且及门。希亮即勒兵阻水拒之,命持满无得发,士皆植立如偶人。甲射之,不动,乃下马拜请死,吏士皆欲斩甲以徇,希亮独治为暴者十余人,使甲以捕盗自赎。

    皇佑元年,移滑州。奏事殿上,仁宗劳之曰:“知卿疾恶,无惩沈氏子事。”未行,诏提举河北便籴。都转运使魏瓘劾希亮擅增损物价。会河溢鱼池埽,且决,希亮悉召河上使者,发禁兵捍之。庐于所当决,吏民涕泣更谏,希亮坚卧不动,水亦去,人比之王尊。数上章请老,不允,移知凤翔。仓粟支十二年,主者以腐败为忧,岁饥,希亮发十二万石贷民。有司惧为擅发,希亮身任之。是秋大熟,以新易旧,官民皆便。于阗使者入朝,过秦州,经略使以客礼享之。使者骄甚,留月余,坏传舍什器,纵其徒入市掠饮食,民户皆昼闭。希亮闻之曰吾尝主契丹使得其情使者初不敢暴横皆译者教之吾痛绳以法译者惧其使不敢动矣况此小国乎乃使教练使持符告译者曰:“入吾境,有秋毫不如法,吾且斩若。”使者至,罗拜庭下,无一人哗者。英宗即位,迁太常少卿。始,州郡以酒相饷,例皆私有之,而法不可。希亮以遗游士之贫者,既而曰:“此亦私也。”以家财偿之。遂借此上书自劾,求去不已,坐是分司西京。未几致仕,卒,年六十四。

       Oxford University has introduced confidence classes for female students to get them to compete for jobs in future and win chances to work in best companies.

       They may be young and gifted, but research at the excellent institution has found that female undergraduates(大学生)are shying away from applying for jobs in banking, finance, management consultancy(咨询), engineering and resource management. Partly as a result, starting salaries for women when they graduate are on average £2,000 to £3,000 lower than their male counterparts.

    “Women are earning less on leaving Oxford.It is ridiculous,”said Jonathan Black, the careers service director at the university.“We have high quality and high achieving students of both genders.But it appears that women are selecting lower paid jobs. They accept more prejudice in certain industries and are saying 'I won't struggle for that really high paid job'. We are not trying to push loads of women but we are trying to say, you should feel able to apply for these sorts of jobs.Boys seem to have more self­confidence and see the bigger picture generally, even though their self­belief is not necessarily based on any greater academic advantage.”

       The four­day programme at Oxford will help 45 female undergraduates improve their self­confidence and decision­making, think positively and build up their strengths. Confidence training will teach them how to deal with the opposition and challenging situations.

       Successful female employees from RBS and BP, which are supporting the course, will talk about their lives and careers. RBS's involvement follows a promise by the bank to increase its national percentage of female graduate applications from 35 percent to 50 percent by 2014.

       Sophie Kelley, 20, studying law at Oxford, is hoping the course will make her more confident in courses and interviews.“I am applying to London's law firms for vacation schemes and it is so competitive,”she said.“The rejection letters don't give any real feedback(反馈), so I'm expecting the programme might give me a hand and some advice.”
