  • A. [宋] 欧阳修
    B. 农者,天下之本也,而王政所由起也。古之为国者未尝敢忽,而今之为吏者不然,薄书听断而已矣,闻有道农之事,则相与笑之曰:鄙。夫知赋敛移用之为急,不知务农为先者,是未原为政之本末也。知务农而不知节用以爱农,是未尽务农之方也。
    C. 古之为政者,上下相移用以济。下之用力者甚勤,上之用物者有节,民无遗力,国不过费,上爱其下,下给其上,使不相困。一夫之力,督之必尽其所任;一日之用,节之必量其所入。一岁之耕,供公与民食,皆出其间而常有余。故三年而余一年之备。今乃不然,耕者,不复督其力;用者,不复计其出入。一岁之耕供公仅足,而民食不过数月。甚者,场功甫毕,簸糠麸而食秕稗,或采橡实、畜菜根以延冬春。不幸一水旱,则相枕为饿殍。此甚可叹也!
    D. 国家罢兵, 三十三岁矣,兵尝经用者老死今尽,而后来者未尝闻金鼓、识战阵也。生于无事而饱于衣食也,其势不得不骄惰。今卫兵入宿,不自持被而使人持之;禁兵给粮,不自荷而雇人荷之。其骄如此,况肯冒辛苦以战斗乎?就使兵耐辛苦而能斗战,虽耗农民,为之可也。奈何有为兵之虚名,而其实骄惰无用之人也。
    E. 古之凡民长大壮健者皆在南亩,农隙则教之以战,今乃大异,一遇凶岁,则州郡吏以尺度量民之长大而试其壮健者,招之去为禁兵;其次不及尺度而稍怯弱者,籍之以为厢兵。吏招人多者有赏,而民方穷时争投之。故一经凶荒,则所留在南亩者,惟老弱也。而吏方曰:不收为兵,则恐为盗。噫!苟知一时之不为盗,而不知终身骄惰而窃食也。古之长大壮健者任耕,而老弱者游惰;今之长大壮健者游惰,而老弱者留耕也。何相反之甚邪!然民尽力乎南亩者,或不免乎狗彘之食,而一去为僧、兵,则终身安佚而享丰腴,则南亩之民不得不日减也。故曰有诱民之弊者,谓此也。
    F. (选自《欧阳文忠公集》,有删改)

  • [单选题]CGUATEMALA CITY (Reuters) – A fish that lives in mangrove swamps(红树沼泽)across the Americas can live out of water for months at a time, similar to how animals adapted(适应)to land millions of years ago, a new study shows.
  • A. The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木),said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.
    B. The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
    C. The new scientific discovery came after a trip to Belize.
    D. “We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
    E. In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
    F. Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
    G. Further studies of the fish may tell how animals changed over time.
    H. “These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡)from water onto land,” Wright said.
    I. 49. The Mangrove Rivulus is a type of fish that _______.
    J. likes eating nuts
    K. prefers living in dry places
    L. is the longest living fish on earth
    M. can stay alive for two months out of water
