   13.But as diet and health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular 1 trend in height.


  【分析】复合句。as引导时间状语从句,主句主干为children and adolescents have increased in heigh to on average 为插入语;a pattern known as...补充说明主句,其中过去分词结构known as...作a pattern的后置定语。
  【译文】但是随着饮食和健康水平的提高,儿童和靑少年的平均身高每20年增加大约1.5英寸,这种模式被称作“身高长期增长趋势”。
  【点拨】on average意为“平均起来,一般来说”,也可说成on an average。该短语在句中的位置比较灵活,可以放在句首、句中和句尾。
  【临摹】在全世界,美国人的平均身高是最高的。
  语法拓展
  现在分词和过去分词作定语的异同
  1)单个分词作定语,不管是现在分词还是过去分词,通常放在被修饰词之前;而分词短语作定语,通常放在被修饰词之后;对something等不定代词进行修饰时分词也要放在所修饰的词的后面。
  2)一般来讲,及物动词的现在分词形式修饰事物,过去分词形式修饰人,如:a surprising result一个惊人的结果;surprised girls吃惊的姑娘们。
  3)过去分词表示被动和完成的含义,而现在分词表示主动和进行。
  14.Moreover, even though human have been upright for million of years, our feet and back continue to struggle with bipedal posture 2 and cannot easily withstand repeated strain imposed by oversize limbs.
  【分析】复合句。 even though引导让步状语从句,其中for millions of years作从句的时间状语,主句的主语是our feet and back,由and连接的两个动词结构continue to struggle和cannot easily with and并列作谓语。
  【译文】此外,虽然人类直立行走数百万年了,但我们的双足和背仍然在与两足行走的姿势作斗争,很难承受过长肢体带来的持续压力。
  【临摹】强者能在命运之风暴中奋力拼搏。
