父亲的船 高巧林

①父亲拥有一条船。坚厚的舱壁、宽阔的舷板、稳健的橹桨……总之,无一不是我幼小心目中神圣而尊严的精神依托。

②奶奶曾经告诉我,一个旭日东升的早晨,父亲摇船去了村东的大湖,把我的胎盘扔进汹涌的浪涛里。我听了一震!奶奶却笑了——“湖神会赏你一副好胆气,长大后才可做像你父寺一样的男子汉!”

③父亲的船,驶进我的童年,在冗长蜿蜒的水道上荡漾,颠簸。悠悠的橹桨边泛起一泓泓欢乐的笑靥和委屈的泪。

④那天,是我永远难忘的日子。

⑤一丝纤细的牛草,悄悄地把我的睡梦牵醒。我揉开惺忪的眼帘,携上心爱的木刻小舟,还有一只赭纹密布的海碗,跃上了父亲的船。

⑥晨风中传来咿咿呀呀的橹桨曲。父亲脱下热烘烘的衣衫,披在我寒颤颤的肩背;又从海碗中取来黄乎乎的面枣,塞进我稚嫩的手窝。蓦然回首,村里的那棵银杏树,已在遥远中忽隐忽现,唯独我心爱的木刻小舟寸步不离地尾随着父亲的船绳。我仿佛第一次看见了生活中的父亲和我,继而,懵懂的心田里流过一股淡淡的酸涩。

⑦江风紧了,父亲上岸拉纤。我立在船头上看见,父亲微驼的背上拽着一根粗大的绳索,艰难的步履在尘沙飞扬的岸滩上,写下一串深沉的脚印。我再也站不住了,满腔的疚意燃成一团小男子汉的火焰——我收起舷边拖牵着的木刻小舟,蹬的一下跳上岸去,自个儿奔跑起来!

⑧父亲那血红的牛一般的双目中,顿时现出莫名的恼怒和痛苦,骂道:“才十三岁的人蛋,就不听话啦!”

⑨我流泪了,泪水流成个白亮亮的小河……

⑩傍晚,我从门槛缝里偷出一把钥匙,蹑手蹑脚地开启了父亲的船锁,第一次在村前的小河里摇开属于我的橹声。调皮的船头,顶了小河埠,又撞了竹架桥。歇橹看时,手窝里磨起了透亮的泡泡。

⑪父亲站在河岸边,投来一束慈祥而欣慰的目光,手里还捧着我那只心爱的小木舟。父亲正重温他早已逝去的童年。

⑫夜里,我在梦境中真的成了男子汉——独自摇着父亲的船,去了村东的大湖里,尽情又浪漫地摇呀摇……(选自《优秀千字散文选》)

Anne Whitney, a sophomore (大学二年级学生) at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go in to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer. My low grades on the tests did not show what I knew to the teacher. “Another student in biology had similar experiences. He said, "My first chemistry test was very difficult. Then, on the second test, I sat down to take it, and I was so nervous that I was shaking. My hands were moving up and down so quickly that it was hard to hold my pencil. I knew the material and I knew the answers. Yet I couldn't even write them down!"

  These two young students were experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the extreme tension and nervousness. Contrary to people’s common belief that poor grades are often a result of poor study habits, sometimes test anxiety plays a role in students’ achieving low grades. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.

  Special university advising courses try to help students. In these courses, advisors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the tests show their anxiety is high, the students can take short courses to help them deal with their tensions. These courses teach students how to relax their bodies. Students are trained to become calm in very tense situations. By controlling their nervousness, they can let their minds work at ease. Learned information then comes out without difficulty on a test.

  An expert at the University of California explains, " With almost all students, relaxation and less stress are felt after taking our program. Most of them experience better control during their tests. Almost all have some improvement. With some, the improvement is very great. "
