紫丁香

  五月的花园里,飘荡着紫丁香浓烈的香味。小蜜蜂深深地吸了一口气,香得浑身发颤,轻纱般的翅膀都跟着抖起来。“嘿,真香!香得叫人心醉!……丁香花真好呀!”

  “你可别太独断了!”小蝴蝶摆动着两根触须说,“你没瞧见,玫瑰花谱进了歌曲,多艳丽!还有秋菊,又清香,又俊逸!就别提牡丹多动人了!”

  “可是,谁都比不上紫丁香!”

  “紫丁香有什么!看看她的小模样吧!小脸蛋多晦气。”小蝴蝶一口咬定。

  小蜜蜂沉默了,仿佛有点伤心呢。

  “你怎么不讲话了?”小蝴蝶像打了胜仗似的,叉着腰问道。

  “像你这样不近情理,我讲什么呢?”小蜜蜂痛苦地摇摇脑袋,“你为什么只看外表?即使只看外表,丁香花也绝不像你讲的那样!”

  蝴蝶瞪起了眼睛:“那么,你喜欢丁香花又有什么根据呢?”

  小蜜蜂摘下一片丁香花的叶子,说:“为了酿出沁人肺腑的芳香,紫丁香花把苦味全留给自己了。你尝尝她的叶子,她的汁……多么苦啊!”

  “把苦味留给自己,把芬芳献给大家,这样美丽的花,这样美丽的心灵,难道不是最值得称赞的吗?”

C

A caring mother is the single most important factor in preventing teenagers from abusing(滥用)drugs and alcohol,researchers said on Friday. An international study showed that teenagers living with both parents are less likely to suffer from alcohol and drug problems,and a strong maternal bond is the most effective way to fight against them.

“These findings suggest that living with both parents may prevent drug use.”said Dr.McArdle of Newcastle University in northern England, who led the study.“They also suggest that attachment(感情眷念),particularly to mothers,is a more effective factor and that this is truly across cultures and substances.”   

The report, which is published in the journal Addiction, involved nearly 4,000 teenagers in England, Ireland, Italy, Germany and the Netherlands. They were questioned about their use of several kinds of drugs and alcohol. The teenagers also filled in questionnaires about their relationship with their parents and grandparents, how well they were supervised(监护)after school and whether they were allowed to meet friends at home.

“Both the quality of family relationships and the structure of families have significant influences on youth drug use,” McArdle said in a statement. But he added a strong maternal bond offered the greatest protection against developing drug habits.

The rate of drug abuse among teenagers living with both parents and who had a good relationship with their mother was 16.6 percent. If either factor was missing ,the drug abuse rate rose to 32 percent.More than 42 percent of teenagers living in one parent families who did not have a strong bond with their mother used drugs.

Drug prevention campaigns in British schools and on television warn teenagers about the danger of drugs and alcohol but McArdle said no one is dealing with the problem of their parents’ responsibility.

B.17-year-old Kate supervised by her single mother.

D.19-year-old Mark cared by his parents.
