30. (1) 第一题是学者发现（谓语动词是过去时）……，基于1990年一个规定还不是什么的，然后一个长划线if…谓语一般现在时…，…将来时…下面选项主要是在时态上有出入，还有词序和代词it、 those什么的 (2) 其他题只记得考点了：考到了 so that， (3)考到了对比，划线部分是最后，记得选项里面有the number of those …… 回忆此预发点：so that以及经常用来比较的so as to 以og12－039为例 In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled so as to marry Anne Boleyn. (A) so as to marry
用法不当
详细看右面 (B) and so could be married to
so在此有非常强烈的因果关系，表明结束了去QC的婚姻必然产生和Anne结婚的结果。这个是不正确的。对比D选项看，could一词表达了可能或许的意思，更合适。 (C) to be married to
主动大于被动 (D) so that he could marry
正确 (E) in order that he would marry
＊针对A选项：so as to 一定要是能明确表示主语的时候简洁使用，而主语不确定就不能用 so as to 。在此题中，marry是可能有指代不明的嫌疑，可能是King Henry也可能是Queen Catherine。 其次， so as to 是用于简单的主系表结构！！！其次要求逻辑主语始终一致。所谓简单主系表结构，拿一道题目举例：Climatic shifts are so gradual as to be indistinguishable at first from ordinary fluctuations in the weather. 这题不用so as to首先它不是简单的主系表结构，逻辑的表达显然不如so that清晰。并且前面有2个人名，不是说逻辑主语不一致，而是会显得confusing 以og12－065 In a plan to stop the erosion of East Coast beaches, the Army Corps of Engineers proposed building parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer, so that it absorbs the energy of crashing waves and protecting the beaches. (A) act as a buffer, so that it absorbs
平行 (B) act like a buffer so as to absorb
act as是固定搭配＋平行＋so as to～也有表示目的结果的意思，但是表示太笨拙而且与后面不平行 (C) act as a buffer, absorbing (D) acting as a buffer, absorbing
不平行 (E)
acting like
a buffer, absorb
同上 以prep174为例 Often major economic shifts are so gradual as to be indistinguishable at first from ordinary fluctuations in the financial markets. A. so gradual as to be indistinguishable B. so gradual so that they can be indistinguishable C. so gradual that they are unable to be distinguished D. gradual enough not to be distinguishable E.
gradual enough so that one cannot distinguish them 正确答案A so 之后的gradual的逻辑主语为major economic shifts as to之后的 be indistinguishable的逻辑主语为major economic shifts 二者一致。所以so as to不仅仅是idiom还是最优的结构，优于so that 句式（c选项) 而且，be able to do 是不能用被动的，can才可以用被动。（白勇语法） 最后来个NN们的总结 ＊总结区别so as to和so that的用法 NN1：so as to,和so that的差别, 基本上,so as to动作执行者就是主句中的主词. NN2：so as to 和so that 的另一重要区别是:so that 中包含了时态,在这种情况下,不能用so as to 代替,在别处也见过这种情况,具体哪里记不清了.反过来,对于so as to ,如果没能表达从句部分正确的动作主体,需要用so that 来代替,表示与主句不同的动作主体进行so that 后面的行为. 找到一些例题来区别： 88.The Emperor Augustus, it appears, commissioned an idealised sculpture portrait, the features of which are （so unrealistic as to constitute ）what one scholar calls an “artificial face.” (A) so unrealistic as to constitute (C) so unrealistic that they have constituted 136.Although schistosomiasis is not often fatal, （it is so debilitating that it has become an economic） drain on many developing countries. (A) it is so debilitating that it has become an economic (C)
so debilitating is it as to become an economic NN： so...as to是固定搭配，通常中间不加入主语成分eg. it is or is it, 这儿我觉得如果１３６变成so debilitating as to become an economic肯定是优选选项（在不考虑整个句子的情况下）。 另外：become是瞬间动词，可以用has become可以表示已经完成不再继续, 而constitute是延续动词，用has constitute 也表示完成了的动作不再继续是不是不太好？ NN总结 1. so as to ... = in order to ..., 它后面跟的不是句子, 在它后面部分的逻辑主语本来就在前面. 当然前后一至了. 2. so that ... = so + that 引导的从句, 没有要求过从句和主句的主语一致. 正如你指出, so that 有两重用法: 1) 相当于in order that, 即你所说的表目的. 如: I stopped so that you could catch up. 2) 相当于with the result or consequence that, 即你所说的表结果. 至于是表目的还是表结果,没有助动词,几乎一定表结果. 但有助动词时, 要根据句子意思来决定.助动词或情态动词不是判断的依据.例如: I was just careless so that you could win this time. (我不过是大意了, 所以这次你才能赢的.) |
