第284句 职业培训
But, for a small group of students, professional training might be the way to go since well-developed skills, all other factors being equal, can be the difference between having a job and not.
译文：但是对少数学生来说，职业培训也许是条可取之路，因为在其他因素相同的情况下，技能的娴熟程度是能否得到工作的关键。
点睛：本句是个复合句，主句的主干为…training might be the way…。介词短语for a small group of students表明所指的对象。主句之后是由since引导的原因状语从句，该从句的主干为…skills... can be the difference... Between...and...。all other factors being equal是一个独立主格结构，在句中作条件状语。句尾的not是not having a job的省略形式。
考点归纳：独立主格结构是由名词／代词+分词／分词短语构成的一种独立结构，用于修饰整个句子，而不是一个词或短语。独立主格结构中的名词或代饲与其后的分词（短语）构成逻辑上的主谓关系。这种结构与主句不发生句法上的联系，且位置相当灵活，可簧于主句前、主句末或主句中，常由逗号将其与主句分开。
*需特别注意的是，独立主格结构与主句之间不能使用任何连接词。
1)Night enshrouding the earth, nobody could make out what the dark mass was from a distance.
黑夜笼罩大地，谁也看不清远处黑压压的一片是什么东西。（逗号前为独立主格）
2)He lay at full length upon his stomach, his head resting upon his left forearm.
他的脊背朝天，四肢伸展，头枕着左臂，直挺挺地趴伏着。
3)The coward was backing, his face being deathly pale, toward another room.
那个胆小鬼向另一个房间退去，脸色煞白。
*独立主格结构多用于书面语，尤其是描述性语言中，在口语和非正式文体中，一般用从句或两个句子来代替。例如，上述例句可变为：
1) Because night enshrouded the earth,nobody could make out what the dark mass was from a distance.
2) He lay at full length upon his stomach. His head rested upon his left forearm.
3) The coward was backing toward another room. His face was deathly pale.
*独立主格结构在句中一般作状语，表示时间、条件、原因、伴随状况等。
1)作时间状语
The governor pondering the matter, more strikers gathered across his path.=While the governor was pondering the matter, more strikers gathered across his path.
总督思考这个问题时，更多的罢工者聚集在他要通过的路上。
2)作条件状语
Weather permitting, they will go on an outing to the beach tomorrow.=If weather permits,they will go on an outing to the beach tomorrow.
如果天气允许的话，明天他们将组织一次海滨小游。
3)作原因状语
The storm drawing near, the navvy decided to call it a day.=Since the storm was drawing near, the navvy decided to call it a day.
由于暴风雨即将来临，那个挖土工人决定收工。
4)作伴随状语
