请各位杀鸡好友多多指教。

主要是看过解释以后，仍不能理解的细节问题。OG13 sc。

68. Outlining his strategy for nursing the troubledconglomerate back to health, the chief executive’s plans were announced onWednesday for cutting the company’s huge debt by selling nearly $12 billion inassets over the next 18 months.

答案(D) executive announced plans Wednesday to cut thecompany’s huge debt by selling nearly $12 billion in assets over the next 18months

请问，在wednesday前不需要介词on么？

69. Affording strategic proximity to the Strait ofGibraltar, Morocco was also of interest to the French throughout the first halfof the twentieth century because they assumed that if they did not hold it, their grip on Algeriawas always insecure.

答案(B) without it their grip on Algeria would never besecure

  做题的时候，很不解答案中it指代的是什么？
  请问，如何才能快速准确定位题目和答案中代词的指代对象呢？

  70. The first trenches that were cut into a 500-acre site at TellHamoukar, Syria, have yielded strong evidence for centrally administeredcomplex societies in northern regions of the Middle East that were arisingsimultaneously with but independentlyof the more celebrated city-states of southern Mesopotamia, in what is nowsouthern Iraq.

  答案(E) cut into a 500-acre site at Tell Hamoukar, Syria,have yielded strong evidence that centrally administered complex societies innorthern regions of the Middle East arose simultaneously with but

答案中的CUT是不是已经是被动语态了，表示trenches是被cut出来的，此时直接用cut来修饰trenches？？

73. Unlike the original National Museum of Science andTechnology in Italy, where the models are encased in glass or operated only bystaff members, the Virtual Leonardo Project, an online version of the museum,encourages visitors to “touch” each exhibit, which thereby activates the animated functions of the piece.

答案(D) exhibit and thereby activate

og的解释是D Correct. The agent of the action is clearlyindicated by the grammatical structure of the sentence; visitors are encouraged to “touch” … andthereby (to) activate.

  这里面，to被省略掉了。请问，如何判断to是被正确的省略了，还是被错误的丢掉了？？我做题的时候，想到了要找这个to do的平行，可是没想到，答案在这里省略掉了这个to。真头疼。


  77. A 1972 agreement between Canada and the United States reduced the amount of phosphates thatmunicipalities had been allowed to dump into the Great Lakes.

  答案(D) reduced the amount of phosphates that municipalitiesare allowed to dump

  请问，agreement 的reduce 效果不是持续到现在么？为什么停止在1972年的那一刻？为什么不用reduces说明agreement的作用一直保持着？

  排版不好，请各位好友见谅。还请各位不吝指教。

68, on 没什么问题，它的最主要的错误在于状语和主句主语不一致。

69，it 指代Morocco ，多看两遍句子自然就明白了。

70, cut 这里是过去分词做定语修饰The first trenches。

73，省略 to，因为主语和谓语一致，连词and 后可以省略。

77，注意1972 年，并非现在发生，而且是否现在还起作用未知，所以正常逻辑思维下应为一般过去式。

68. 摘自：TerraceHo
Wednesday有一種用法，就是作為adverb，表示on Wednesday。不過這種用法主要在北美用的，例如See you Wednesday.在這裡wednesday作為adverb修飾announce，表示announce的時間。

69. 虚拟语气，it的指代个人觉得是Morocco。推荐你这个关于代词的指代帖子http://forum.chasedream.com/GMAT_SC/thread-15734-1-1.html

70. 个人觉得were cut与cut都是正确的，但是从简洁而又不歧义的角度看的话，选cut比较好。

73. to的省略我答不上，不过推荐个知识点，一般看见thereby, then, as a result, in turn这些词，都是辅助平行项的插入词。

77. 个人觉得题目设定的时间为1972这个时间点，属于发生在过去的事情，只是对过去的这件事一个陈述。也就是说，1972年这个法案设立后，在当时减少了垃圾量。而如果使用reduces的话，则会造成是时态上的不符合。而且一般现在时表示一般状态、习惯动作、客观规律和永恒真理，reduce在法案中的这个动作属于这个范畴。

如果需要一个持续性的表达的话，句中应该出现相应的时间词。
如：A 1972 agreement between Canada and the United States has reduced the amount of phosphates that municipalities allow to dump into the Great Lakes for 30 years.

个人观点，还请大家斧正

继续提问。

OG13 SC 正确句子

63.When Congress reconvenes, somenewly elected members from rural states will try to establish tighterrestrictions on the amount of grain farmers will be allowed to grow and toencourage more aggressive sales of United States farm products overseas.
   后面黄色部分怎么理解，是on的宾语么？on后面的部分主语是the amount of farmers么？

81.  Fossils of the arm of a sloth,found in Puerto Rico in 1991, have been dated at 34 million years old, makingthe sloth the earliest known mammal on the Greater Antilles Islands.
   我的理解：主句是Fossils have been dated...       可是我想不明白，making the sloth 在后面做什么成分？是doing形式的定语来修饰fossils么？距离是不是有点远了？

90.The results of the company’scost-cutting measures are evident in its profits, which have increased 5percent during the first 3 months of this year after falling over the lasttwo years.
   请问，为什么要用have increased这个时态？从哪里判断出来的？？？

谢谢各位好心人！

1.看不出LZ指的黄色部分是哪里，这里只能告诉你ON 后面不是主语。

2.making the sloth 这里是结果状语，不是修饰fossils。而是表示 Fossils have been dated at 34 million years old 的结果。

3.现在完成时是根据前面的are 和从句中的during the first 3 months of this year结合句意判断的。
