    When I was eighteen, I couldn't wait to get my first job, which meant I made the first step toward adulthood.

    But it was difficult to get a work permit. One day I was dropped off by my parents at the1, where applicants took their physical tests for work permits. Although I had night blindness, my vision was clearer during the day, which helped me walk 2 by myself. Then the doctor began the 3. He looked into my eyes with a bright light. “I suggest your parents take you to an eye specialist,” he said, “I  4 you have a retinal(视网膜)disease. If you do, you will never 5a day in your life… ”

But still, during daylight, I could walk without 8. I could read, but not for hours. My eyes began to 9 and words slipped off the page when I read more than a few pages.

阅读下面的文字,完成小题。

       吴育,字春卿,建安人也。父待问。累官光禄卿,以礼部侍郎致仕。育少奇颖博学,举进士,试礼部第一,中甲科。除大理评事,迁寺丞。历知临安、诸暨、襄城三县。

       庆历五年,拜右谏议大夫、枢密副使。居数月,改参知政事。山东盗起,帝遣中使按视,还奏:“盗不足虑。兖州杜衍、郓州富弼,山东人尊爱之,此可忧也。”帝欲徙二人于淮南。育曰:“盗无足虑者,小人乘时以倾大臣,祸几不可御矣。”事遂寝。向绶知永静军,为不法,疑通判江中立发其阴事,因构以危法中之,中立自经死。绶宰相子,大臣有营助,欲傅轻法。育曰:“不杀绶,无以示天下。”卒减死一等,流南方。

       育在政府,遇事敢言,与宰相贾昌朝数争议上前,左右皆失色。育论辨不,乃请曰:“臣所辨者,职也;顾力不胜,愿罢臣职。”乃复以为枢密副使。帝语大臣曰:“吴育刚正可用,第嫉恶太过耳。”一日,侍读禁中,帝因语及“臣下毁誉,多出爱憎,卿所当慎也” 。育曰:“知而形之言,不若察而行之事。圣主之行,如日月之明。进一人,使人皆知其善,出一人,使人皆晓其恶,则阴邪不能构害,公正可以自立,百王之要道也。”

       育性明果,所至作条教,简疏易行而不可犯。遇事不妄发,发即人不能挠。辨论明白,使人听之不疑。初尹开封,范仲淹在政府,因事与仲淹忤。既而仲淹安抚河东,有奏请,多为任事者所沮,育取可行者行之。
