南海旅次

曹松^①

忆归休上越王台，归思临高不易裁。

为客正当无雁处^②，故园谁遣有书来。

城头早角吹霜尽，郭里残潮荡月回。

心似百花开未得，年年争发被春催。

【注】①曹松，晚唐诗人，舒州（治所在今安徽潜山）人，因屡试不第，长期流落在今福建、广东一带。这首诗就是他连年滞留南海（郡治在今广州市）时的思归之作。②无雁处：大雁在秋天由北方飞向南方过冬，据说飞至湖南衡山则不再南飞了。南海在衡山以南，故曰“无雁处”。

花生花

    ①人们常常咏赞烂漫的樱花，雍容的牡丹、圣洁的白莲，我却要咏赞貌不惊人的花生花。我觉得花生花虽平凡，却蕴藏着另一种美。

    ②花生的花，一般在七月开，青青的花生株上，露出一点一点鲜黄的嫩苞。清晨浴着露水，湿漉漉的；中午，反射着阳光，亮晶晶的。就在这时，小苞绽开了！一朵两朵，娇小而醒目地点缀在万绿丛中。几天后，到了盛花期，那时，你若从花生地边走过，一眼便可见到那些小小的黄花疏密有致地洒在椭圆形的绿叶丛中。绿里透黄，犹如翠绿的大毯子镶着粒粒的金灿灿的宝石。微风吹过，送来缕缕清香，沁人心脾。

    ③花生花没有婀娜的姿态，看上去的确比不上樱花、牡丹、白莲。不过记得一位名人说过：不是因为美丽才显得可爱，而是因为可爱才显得美丽。我也并非初次看到花生花就觉得它美的，我对它产生特殊的感情，是有一段经历的——

    ④三年前，我和妈妈路过一块花生地，看见那星星点点的小黄花，刚想伸手去采一朵玩玩。

    ⑤“不要采！”妈妈制止我，“花生的花，不像桃花、梨花、花生的花，没有一朵是空花。开一朵花，地下就长一颗花生；你采掉一朵，就要少长一颗花生。”

    ⑥“是真的？”

    ⑦“妈妈还骗你？弦子，桃花、梨花容易谢，即便结出果子，也挂在枝头，可是花生花却很谦虚，它把果实埋在地下，不让人知道花生结果子是自己的功劳。”

    ⑧妈妈的话使我感到惊奇，同时也引起了我的深思：多可爱的小黄花！千千万万的小黄花默默地悄悄地谢，最后钻入土里长出千千万万颗花生。

    ⑨从此，我对花生花产生了特殊的感情。每看到它，我就联想到那些朴实无华，不慕名利，默默无闻地为人类贡献自己的千千万万个普通劳动者。

   Many years before the United States was founded(建立), Americans had already invented barbecues. But the first barbecues, in fact ,were the invention of the Taino Indians of Haiti, who dried their meat on raised frames(架子)of sticks over fires. Spanish explorers spelled the Taino word as barbacoa, and as time passed, English settlers along the Atlantic coat had their own barbecues.
   One summer day in 1773, Benjamin Lynde, a citizen of Massachusetts, wrote in his diary, "Fair and hot ; Browne;hack overset."That is , on a bright and hot day he went to the Brownes to attedn a barbecue, and his carriage(马车)fell over. It shows that the barbecue had its social occasion by that time. Large animals would be roasted whole on frames over hot fires, and neighbours would be invited to dinner.
   In later centuries, as settlers moved to the west, the barbecue went along with it, reaching an especially large size in Texas, where a pit(坑)for fuels(燃料) such as tree branches might be over ten feet deep. Today , the barbecue grills(烧烤架)which are fueled by charcoal(木炭) or electricity are likely to be small and easy to move , and can cook only parts of an animal at a time, but people still have barbecues out of doors and always invite their neighbours or friends over.
