  三、重点句型
  
  1. should引导的虚拟倒装句

  A. Would you beB. Should you be

  【考点解析】 答案为B。当if条件状语从句中含有助动词were, had或should时,可以省去if,将were, had或should提到主语前面,构成倒装句。本题正常句序是If you should be fired, your health care and other benefits will not be immediately cut off.
  2. 过去分词短语做状语
  【课文原句】 Located in southern Austria, Kitzbuhel is a paradise for skiers. 基茨布厄尔位于奥地利南部,是滑雪运动爱好者的天堂。
  【经典考例】 ________ by a greater demand of vegetables, farmers have built more green houses.(2007浙江)
  A. Driven B. Being driven
  C. To drive D. Having driven
  【考点解析】 过去分词作状语,其逻辑主语是句子中的主语,表示被动或完成意义。答案为A。根据语境:农民被蔬菜的大量需求所驱动,建起了更多的温室大棚。分词与其逻辑主语farmers在逻辑上是被动关系,应使用过去分词作状语。
  3. 句型There is no need to do
  【课文原句】 There is no need to worry if you have never skied before. 如果你以前没有滑过冰,也没必要担心。
  【经典考例】 He will be better soon. There is no need ________.
  A. to worry about B. worried
  C. to be worried D. to be worried about 【考点解析】答案为C。考查搭配There is no need to do sth. “没有必要……”。A项中的 worry about相当于一个及物动词,与句意不符。
  4. 拟人写作手法
  【课文原句】 The city saw a series of fierce fights between blacks and whites in the 1960s and Dr. King was shot and killed in 1968. 在20世纪60年代这座城市目睹了黑人和白人之间一连串的冲突以及金博士在1968被枪杀。
  【经典考例】 The year 2008 ________ remarkable changes in Beijing’s landscape.
  A. metB. saw C. readD. looked
  【考点解析】答案为B。The year see…是一种拟人化的写作手法,以增强句子的表现力。See意为“(在某段时间或某地)发生;经历”。这种句子的谓语动词通常是see, witness, tell, show, make, bring, enable, remind, prevent, keep等。
  5. that引导的同位语从句
  【课文原句】 There are signs that a new, different South is coming out of its dark past. 种种迹象表明一个崭新的截然不同的南部正在走出过去的黑暗。
  【经典考例】 A warm thought suddenly
  came to me ________ I might use the pocket money to buy some flowers for my mother’s birthday. (2007 安徽卷)
  A. if B. when C. that D. which
  【考点解析】 答案为C。由同位语从句对名词thought加以补充说明,由于主句的谓语比较短,而同位语从句I might use the pocket money to buy some flowers for my mother’s birthday比较长,所以这个从句就没有紧接在它所说明的名词后面。
  6. 过去分词作定语
  【课文原句】 Atlanta quickly recovered from the destruction caused by the Civil War. 亚特兰大很快从内战的毁坏中恢复过来。
  【经典考例】 The Town Hall ________ in the 1800s was the most distinguished building at that time.
  A. to be completed
  B. having been completed
  C. completed
  D. being completed
  【考点解析】答案为C。过去分词短语作定语,通常放在被修饰的名词之后,相当于一个被动意义的定语从句。☆
