  2. If we look only for the correct answer and reject ideas that do not provide a complete answer, we may get stuck. 如果我们只找正确答案,拒绝那些不能给我们完整答案的想法,那么我们就可能被框住。

  ①A+谓语+倍数+as+形容词/副词(原级)+as+B;
  ②A+谓语+倍数+the size/length, weight, height, width, age, price…+of B。例如:
  Asia is four times as large as Europe. 亚洲是欧洲的4倍大。
  Asia is four times the size of Europe.
  =Europe is one fourth the size of Asia. 欧洲面积是亚洲的1/4。
  ③……倍数+as many+可数名词复数+as或……倍数+as+(much+不可数名词+as)。例如:
  We planted five times as many trees as they did.

  (2)如要表示“A比B大/长/高等多少倍”,一般用“A+谓语+倍数+形容词/副词(比较级)+than B”。例如:
  Asia is three times larger than Europe. 亚洲比欧洲大3倍。
  注意:此句型中用比较级时,倍数要减去原来的底数,“是……的4倍”等于“比……大3倍”。
  (3)若表达“这条铁路是那条铁路的8倍长”。有以下几种:
  This railway is eight times as long as that one.
  =This railway is eight times the length of that one.
  =This railway is seven times longer than that one.
  =The length of this railway is eight times of that one.
  注意:两倍可用twice或double表示,一半则用half表示。例如:

  11. What are you accused of? 你因什么而受到起诉?

  The manager declared the meeting open. 经理宣布会议开始。
  They declared him to be the winner. 他们宣布他为获胜者。

  I declared for/against his opinion. 我赞成/反对他的观点。
  14. Therefore, go down on your knees and beg the Duke for mercy. 因此,快去跪下请求公爵宽恕你吧。
  (1)therefore作副词,意为“因此”,表示结果或理由,相当于as a result of that;它不能引导从句,不要把它当连词来用。therefore常常和and一起使用,这时therefore前可用逗号或者不用标点符号;如果不与and连用,therefore前用分号。例如:
  He doesn’t know much about China; therefore he can’t advise me about it. 他对中国不甚了解,因此向我提不出什么建议。
  (2)go down on one’s knees意为“跪下,屈膝”相当于get down on one’s knees; go down on one knee意为“单腿跪下”。例如:
