第二式：非谓语动词做状语的使用
   
　　1．By contrast,when removed from the greenhouse,the protective umbrella,it struggles helplessly against the sudden attack of storms,only tO wither away.
   
　　2．Parents are too eager to mold their kids,disregarding their individuality with a callous attitude toward their personal development.
   
　　3．School—age children are often seen carring bulging bags on their backs,weighed down on their way to and form school every day.
   
　　非谓语动词有四种变现形式，即动词不定式、现在分词、过去分词和动名词。利用这几种非谓语动词形式(动名词不能做状语除外)做状语，能很好地突出信息，取得信息“末尾聚焦（end—weight）”的效果。例1用only加动词不定式表示出乎意料的结果，做结果状语。从而将备受溺爱的孩子们不更世事、不堪一击的惨状和盘托出。例2用现在分词做结果状语，表示一种必然的发展趋势，即结果在意料之中。例3用过去分词做伴随状语，将饱受应试教育摧残的学龄儿童那苦不堪言的情形栩栩如生地勾勒了出来，辛辣的嘲讽宛然可见。当然这几种非谓语动词形式也可放在逗号前面一分句或句子中间，如
   
　　4．Weighing boththese arguments.I can cometOthe conclusionthatthereis no need to take so drastic a step as doing away with this custom.（现在分词做时间状语）
   
　　5．An old peasant,bringing his own food,volunteered as a guide for US.（现在分词做伴随状语）
   
　　非谓语动词做状语到底放在前还是放在后似乎没有绝对的要求。但一般来说，做伴随状语时可前可后做原因状语时放在前面较多，间或放在后面；做时间状语时一般放在句子前，做结果状语时一般放在后半分句，做条件状语时一般放在前面分句，等等。
