【甲】

    臣本布衣,躬耕于南阳,苟全性命于乱世,不求闻达于诸侯。先帝不以臣卑鄙,猥自枉屈,三顾臣于草庐之中,咨臣以当世之事,由是感激,遂许先帝以驱驰。后值倾覆,受任于败军之际,奉命于危难之间,尔来二十有一年矣。

    先帝知臣谨慎,故临崩寄臣以大事也。受命以来,夙夜忧叹,恐托付不效,以伤先帝之明,故五月渡泸,深入不毛。今南方已定,兵甲已足,当奖率三军,北定中原,庶竭驽钝,攘除奸凶,兴复汉室,还于旧都。此臣所以报先帝,而忠陛下之职份也。至于斟酌损益,进尽忠言,则攸之、祎、允之任也。

(节选自诸葛亮《出师表》)

【乙】

    诸葛亮围祁山,南安、天水、安定三郡反应亮。帝遣真督诸军军郿,遣张郃击亮将马谡,大破之。安定民杨条等略吏民保月支城,真进军围之。条谓其众曰:“大将军自来,吾原早降耳。”遂自缚出。三郡皆平。真以亮惩于祁山,后出必从陈仓,乃使将军郝昭、王生守陈仓,治其城。明年春,亮果围陈仓,已有备而不能克。增邑,并前二千九百户。四年,朝洛阳迁大司马赐剑履上殿入朝不趋。真以“蜀连出侵边境,宜遂伐之,数道并入,可大克也。”帝从其计。真当发西讨,帝亲临送。真以八月发长安,从子午道南入。司马宣王溯汉水,当会南郑。诸军或从斜谷道,或从武威入。会大霖雨三十余日,或栈道断绝,诏真还军。真每征行,与将士同劳苦,军赏不足,辄以家财班赐,士卒皆愿为用。真病还洛阳,帝自幸其第省疾。真薨,谥曰元侯。

【注】:①真,指曹真,三国时魏国名将。

    It is not easy getting the attention of tourists away from the well-known white sandy beaches of Byron Bay. But in this relying Australian surf town, a solar (太阳能的)-powered train might just do a good job.

    Opening to the public in December 2017 along a 1.9-mile-long stretch (一段) of track that sat abandoned for more than a decade, the Byron Bay Rail Company has breathed new life into a pair of disused railcars dating back to the 1940s. They're now used to transport passengers between Byron Bay's central business district and the North Beach area. After remaining in service as part of a regional passenger rail network until the early 1990s, the aging railcars were out of service and sat uncared for — almost destroyed by time and unpleasant Aussie climate — in a railyard for more than 20 years. You'd never know it by looking at these nearly 70-year-old workhorses today, though: they've been decorated, equipped, topped with custom-made photovoltaic panels (定制的光电池板) and rearranged to accommodate up to 100 seated beach goers.

    It's those train-top PV panels that truly set the Byron Bay Rail Company's flagship train apart from other heritage rail restoration projects.

    Drawing additional power from a 30-kilowatt solar array (阵列) located atop the train's storage building, the tain is said to be the first in the world to be completely powered by the sun. Solar energy caught by the 6.5-kilowatt train-top solar panels is stored directly in an onboard battery system that powers motors, lighting and the like. When stopped at its home platform, the train pushes into chargers for quick battery top-offs with electricity produced by the storage building's rooftop solar array. The 77 kilowatt-hour battery can hold enough juice for 12 to 15 runs on a single charge. During long periods of cloudiness when the solar arrays don't get enough sun, the train uses the main electric network, supply using renewable energy sold by community-based service Enova Energy.

    The Byron Bay Rail Company's first-in-the-world folly solar-powered train is a good example of historic rail preservation with a 21st century development. Operating as a not-for-profit company, the Byron Bay Rail Company also expected the AU$4 million line to be a way to relieve traffic jam between downtown Byron Bay and the rapidly growing North Beach area. Really, there's no bigger unpleasant thing than sitting in bad traffic for 40 minutes trying to get to the beach.
