  问题难点：“to battle _____ the edge the surest strategy is to develop the unexpected”语法分析？
  
answer: 难度一般，差不多就是托福语法题的水平，词汇量还不多
  
  1.D 比喻的感染力在中是很常见的。
  
  2.D 主句为The engineer plunked down $50,000，主语：The engineer ,谓语动词plunked ，$50,000宾语。retired形容词作定语修饰engineer；in cash 介词短语作状语修饰plunked down；for a mid-size Mercedes 成分不明，似乎为目的状语；as present 介词短语作定语，修饰$50,000；for his wife paid for a purchase 介词短语作目的状语；with money 作方式状语;made in the stock market before作后置定语修饰money.
  
  3.A Danis Hayes提出了本质的悖论，并质问人们怎么能够如此努力的抵抗环境恶化，然而他们现在却发现他们要输掉这场战争了。
  
  4.应该是D吧，是不是battle against， 没见过。整句是个主从复合句，If there is the need to compete in a crowd是从句，“to battle _____ the edge the surest strategy is to develop the unexpected”是主句，to battle _____ the edge the surest strategy是主句主语，is 系动词，to develop the unexpected作表语。
